#1: (Environment) Green Chemistry: Toys—Time to Get Serious Author: adediosLocation: Angel C. de Dios PostPosted: Wed Apr 19, 2006 10:12 am

Toys, Yes, these play a role in educating children. Toys can stimulate one's imagination and thinking. The news article describes a recent winner in a chemistry contest and it is a new toy design. This toy not only brings chemical reactions to a young mind, but also introduces the principles of "green chemistry". With our ever increasing utilization of earth's resources, it is now important to become aware of how much we use, how much we waste, and how much we affect the environment around us. In this lesson, learn more about toys and "green chemistry". It is never too early learn how we could best protect our environment.

Toys — it's time to get serious

What do baker’s yeast, vinegar, salt, soap, hydrogen peroxide and cabbage have in common? They are all ingredients of The Green Machine, a new toy design that won the national "Chemvention" contest based on the theme of the 2005 National Chemistry Week, "The Joy of Toys." The announcement was made at this year’s spring national meeting of the American Chemical Society.
The Green Machine is a home chemistry kit unlike any other. The design team — students from Bridgewater State College in Bridgewater, Mass. — wanted the toy to be just as interesting for young scientists as movies or video games. Their winning design is a chain of five different chemical reactions, with one reaction starting the next.

With Earth Day 2006 just around the corner, the design is even more exciting because it demonstrates principles of green chemistry. Green chemistry aims to reduce waste and pollution by preventing it, rather than by cleaning it up, which is exactly what The Green Machine does by using only safe ingredients and producing only safe products.

The Bridgewater team also made a point to carefully balance the ingredients —just like a perfect cake mix — so that all of the initial ingredients were used up and turned into end-products. Students who saw the design in action at the Green Chemistry Event at the Museum of Science in Boston, Mass., however, may just have been interested in the bubbles, changing colors, moving parts and lights.

The designers think that their design could be improved if it were built using a biodegradable plastic. The team spent $113.80 developing their design and received a prize of $2,000 that will be used to buy computer equipment for the chemistry department.

The American Chemical Society — the world’s largest scientific society — is a nonprofit organization chartered by the U.S. Congress. Its main offices are in Washington, D.C., and Columbus, Ohio. The Society sponsors National Chemistry Week each October, which includes nationwide contests for grades K-12.

Mad about science
Sun Apr 23, 2006
Manila Bulletin

Kids get to outsmart their parents this summer as they learn scientific facts and experiments at the Mad Science® Fire and Ice at Robinsons malls starting this Saturday, April 22.

Following the enlightening National Geographic Caravan event held recently at Robinsons malls, which featured animals and environmental issues, Robinsons brings in another educational event, this time focusing on "science," the branch of knowledge that requires systematic study and method.

"For this year, we have opted to offer something more meaningful for the children to spend their summer by hosting a series of educational tours such as the Mad Science® Fire and Ice Special Event," said Robinsons Malls GM Cornelio Mapa, Jr. at a press conference at Holiday Inn Galleria Manila.

Mad Science is the world’s leading fun science provider founded in Canada in 1993 by Ariel and Ron Shlien, a couple who loved to conduct crazy science experiments.

In 2002, local franchise Funworks Inc., headed by CEO Francis Kong, brought Mad Science into the country to spark Filipino kids’ interest in science.

"Mad Science aims to help our students ages 4–12, to rediscover the fun in learning science through creative experiments and activities," explained Kong. He had left his garment business in order to "educate" children.

Science, perceived by many as a complicated and boring subject, becomes fun and easy with Mad Science’s "edu-taning" classes, which are taught in schools, birthday parties, special events and summer camps.

"Parents will find Mad Science an interesting way to make their kids enjoy learning science because kids love to imagine, explore and experiment and that’s what Mad Science delivers," stressed Kong.

Mad scientists led by Mr. & Mrs. Magnanimous Mark (Mad Science’s most popular scientists according to Kong), will visit Robinsons malls to beguile the audience with mind boggling experiments.

For free, kids will learn how to burn money without actually burning it, suck a boiled egg into a bottle without cutting the egg in half, create movie effects using dry ice or build a rocket, make bubbles or taste a burp, etc.

One favorite experiments is "slimemaking," which Mr. & Mrs. Magnanimous Mark demonstrated for us during the press conference.

For this experiment, you’ll need: glue, glass bowls, water, food coloring, spoon, measuring cup, and sodium borate (borax).

The procedure is quite easy…

First, you have to empty the glue bottle into the first bowl. Then fill the empty glue bottle with water and then pour it into the bowl of glue. Add a few drops of food coloring and stir well.

Next, pour the colored glue into the bowl containing the borax solution, and stir it…And you’ll get a soft, pliable, rubbery glob called "slime."

Amazing! It’s not a trick, because there is an explanation to that, Magnanimous Mark assured us.

Such experiment works because the polyvinylacetate molecules in the glue act like invisible bicycle chains drifting around the water. The borax molecules (sodium tetraborate) on the other hand, act like little padlocks, locking the chain links together wherever they touch the chain.

The locks and chains a inter-connected "fishnet," and the water molecules act like fish trapped in the net.

With this simple experiment, kids can now produce their slimy goo and pretend to be Slimer, the ghost in the Ghostbusters that spewed slime.

To learn more experiments and know more about science, catch Mad Science® Fire and Ice at Robinsons malls on:

April 22 – Pioneer, April 23 – Galleria & Novaliches, May 1 – Manila & Angeles, May 6 – Pampanga & Santa Rosa, May 7 – Dasmariñas, May 13 – Metro East, May 27 – Imus & Lipa.

All shows start at 4 p.m. at the activity center. Admission is free.

#3: Carbon-based quantum dots could mean 'greener,' safer tech Author: adediosLocation: Angel C. de Dios PostPosted: Wed May 24, 2006 7:54 am

Carbon-based quantum dots could mean 'greener,' safer technology in medicine and biology

WASHINGTON, May 23 -- Chemists at Clemson University say they have developed a new type of quantum dot that is the first to be made from carbon. Like their metal-based counterparts, these nano-sized "carbon dots" glow brightly when exposed to light and show promise for a broad range of applications, including improved biological sensors, medical imaging devices and tiny light-emitting diodes (LEDs), the researchers say.
The development, which could help broaden the use of quantum dot technologies, is described in a research communications published online today by the Journal of the American Chemical Society. The paper will appear in the journal's June 7 print edition.

The carbon-based quantum dots show less potential for toxicity and environmental harm and have the potential to be less expensive than metal-based quantum dots, the scientists say. Cheap disposable sensors that can detect hidden explosives and biological warfare agents such as anthrax also are among the possibilities envisioned by the researchers.

"Carbon is hardly considered to be a semiconductor, so luminescent carbon nanoparticles are very interesting both fundamentally and practically," says study leader Ya-Ping Sun, Ph.D., a chemist at the university, located in Clemson, S.C. "It represents a new platform for the development of luminescent nanomaterials for a wide range of applications."

Quantum dots have generated much interest in recent years, especially for potential applications in biology and medicine. These tiny particles -- thousands of times smaller than the width of a human hair -- have been developed from compounds composed of lead, cadmium and, more recently, silicon. But these materials have raised concerns over potential toxicity and environmental harm. As a result, scientists have begun to look for more benign compounds for making quantum dots.

Researchers have known for some time that carbon nanoparticles, due partly to their enormous surface area, have unusual chemical and physical properties quite different from their bulk form. Using nanoparticles produced from graphite, Sun and his associates demonstrated that when these carbon nanoparticles are covered with special polymers, they glow brightly when exposed to light, behaving as tiny light bulbs. The dots glow continuously as long as a light source is present, they say.

The scientists believe that this photoluminescence may be due to the presence of "pockets" or holes on the surface of the carbon dots that trap energy. The polymer coating acts as a "molecular band-aid," enabling light emission from the inside of the polymer casing, they say. Scientists believe that metal-based quantum dots emit light by a somewhat different mechanism.

The two-sided polymer coating allows researchers to attach antibodies or other labeling materials to the carbon dot, says Sun. This could lead to improved dyes for medical imaging and also the development of sensors that light up in the presence of a target, such as anthrax or even food-borne pathogens. In lab studies, the researchers successfully labeled anthrax-like spores with luminescent carbon dots, resulting in glowing spores that were easily viewed under a microscope.

Funding for the current study is primarily provided by Clemson University. The project is also supported with some funding from the federal government.

Boosting intelligence among poor is child's play
Fri Jan 5, 2007 4:05 AM ET
By Jeremy Lovell

LONDON, Jan 5 (Reuters) - Giving pre-school children toys to play with boosts their mental development even if they suffer from malnutrition, a report said on Friday.

The report, published in the Lancet medical journal, said several studies had found a clear link between intelligence and child's play.

"We have done play programmes in Bangladesh where the children are severely malnourished and we have produced up to a nine-point improvement in the IQ of these kids -- just with play," said author Sally McGregor of the Institute of Child Health at University College London.

"Malnutrition on its own is a problem. Malnutrition without mental stimulation is an even bigger problem," she said in an interview.

Green chemistry can help nanotechnology mature, Oregon professor says

Planning now can reduce risks of environmental and health-related side effects
The safest possible future for advancing nanotechnology in a sustainable world can be reached by using green chemistry, says James E. Hutchison, a professor of chemistry at the University of Oregon.

“Around the world, there is a growing urgency about nanotechnology and its possible health and environmental impacts,” Hutchison said in his talk Sunday during a workshop at the annual meeting of the American Association for the Advancement of Science. “There is a concern that these issues will hinder commercialization of this industry.”

Scientists need to take a proactive approach to advancing from the current discovery phase in the creation of nanomaterials into a production phase that is efficient and reduces waste, he said. In his talk, Hutchison suggested a green framework for moving the industry forward.

Nanotechnology refers to research on materials that are nanometer in size – or about 1 billionth of a meter and applicable to virtually every technology and medicine. The field of nanoscience, Hutchison said, is still in the discovery phase, in which new materials are being synthesized for testing for very specific physical properties. During such work, there often are unintended properties of material that potentially can be hazardous to the environment or human health but are, for now, an acceptable risk in secured research environments, he said.

Now is the time, Hutchison said, for scientists to “seriously consider the design of materials, processes and applications that minimize hazard and waste, and this will be essential as nanoscience discoveries transition to the products of nanotechnology.”

Hutchison is a leading U.S. innovator in nanofabrication and assembly processes and is a pioneer in the use of green chemistry, which he also teaches to other scientists around the country at workshops. He also is the leader of the Safer Nanomaterials and Nanomanufacturing Initiative, which is funded by an Air Force Research Laboratory grant to the Oregon Nanoscience and Microtechnologies Institute.

Green chemistry, he argues, can sharply reduce the use of toxic solvents and produce safer products with reduced chances for unintended consequences. It also can provide opportunity for new innovations.

“Green chemistry allows us to think about new space and new parameters,” Hutchison said. “We have the opportunity to develop the technology correctly from the beginning, rather than trying to rework and entrenched technology.”

Hutchison, who is director of the UO’s Material Sciences Institute, is developing diverse libraries of nanoparticles, “in which we systematically bury the structural parameters and use in vivo and in vitro assays to determine the relationship between biological response and structural parameters.”

One such library covers gold nanoparticles for use in basic research. By studying these nanoparticles, he said, researchers can get an idea of what kinds of new electronic, optical and pharmaceutical products eventually may come to market. Hutchison received a patent in 2005 for his synthesis of gold nanoparticles using green chemistry.

Hutchison told the AAAS gathering that he recently published a technique for purifying nanoparticles that uses membranes with nanopores so small that only impurities pass through – a green approach that allows the purification of particles rapidly without using organic solvents. “Before this accomplishment, purifying the material used up 15 or so liters of solvent per gram of particles,” he said. “If solvent is the density of water, that’s 15,000 times more mass used to purify it than we get out of it.”

The nanotechnology industry, Hutchison said, has reached an important moment in time. “There is an opportunity to stay ahead of the curve,” he said. “We should commit ourselves to design these materials and processes to be green from the beginning, and this will provide a lot of freedom from layers of regulation to researchers and companies, allowing for more innovation.”

#10: Helping to establish Green Chemistry -- in Ethiopia Author: adediosLocation: Angel C. de Dios PostPosted: Fri Jun 22, 2007 9:16 am

Helping to establish Green Chemistry -- in Ethiopia

University of Nottingham scientists have been instrumental in helping to establish a pioneering branch of chemistry in Ethiopia.

They have helped to introduce Green Chemistry, an emerging field of sustainable science that will help African nations to meet the challenges of the 21st century.

Green Chemistry — a field in which The University of Nottingham is a world leader — focuses on greener ways of creating chemicals, and is now regarded as one of the major routes to more environmentally-friendly production of the chemicals that underpin modern society.

The work of Nottingham academics with their colleagues in Ethiopia, detailed in the online version of the journal Science, began with a chance meeting four years ago. Today it is sufficiently developed to enable African scientists to participate more fully in the search for new chemicals, processes and techniques that could impact on millions of people.

Much current research is focused on the search for renewable feedstocks and more environmentally acceptable solvents as replacements for petroleum-based products. This makes Green Chemistry particularly relevant to the needs of African countries such as Ethiopia, faced with an increasing demand for chemicals, little or no indigenous oil, and rapidly expanding populations.

The collaboration started with a chance meeting between Dr Nigist Asfaw and Professor Martyn Poliakoff, who heads research into Green Chemistry at The University of Nottingham, while the latter was on holiday in Ethiopia.

Over the next four years, links were gradually developed and strengthened through staff visits, conferences, workshops and collaborative research. Today, the Ethiopian scientists have established an international presence and are on the brink of their first conference for chemists from across the whole of Africa.

Ethiopian PhD student Haregewine Tadesse is currently in the second year of her PhD in Dr Peter Licence’s research group at The University of Nottingham. Haregewine has made a very strong start, having already authored a high-profile scientific paper for publication and addressed a meeting of the RSC Archives for Africa at the Houses of Parliament. A second Ethiopian postgraduate, Mr Bitu Biru, is due to join in September to start a PhD in the subject.

Professor Poliakoff and Dr Licence have co-authored a paper in Science Express with Dr Asfaw and Dr Temechegn Engida, of Addis Ababa University.

They write in Science Express: “Green Chemistry provides a unique opportunity for African chemists because it combines the search for new science with the development of sustainable chemical technologies appropriate to the needs of the community.

“Therefore, the resources of Africa — intense sunlight, unique plant species and enthusiastic young people — present its chemists with scientific opportunities, less readily available in many other countries.

“With modest funding and overseas support, a determined group of Ethiopian scientists has established an international presence within only four years. It is a model which perhaps can be replicated elsewhere.”

Green chemistry is now well established at Addis Ababa University and the collaboration has led to a number of other key developments, notably:

The establishment of Addis Ababa University as an Overseas Chapter of the American Chemical Society, Green Chemistry Institute.
The formation of the Federation of African Societies of Chemistry, bringing together scientists from across Africa.
1st Annual FASC conference to be held in Addis Ababa in September 2007 — with Green Chemistry as its theme.
Nottingham PhD student Haregewine Tadesse and Nottingham academic Dr Robert Mokaya, a Kenyan, spoke at the launch of the Royal Society of Chemistry’s Archive for Africa. The launch of the Archive means that African scientists will have free access to the latest research published in key scientific journals.
Research and staff links between Nottingham and Addis Ababa University, including appointment of Dr Peter Licence as visiting professor, making extended visits to Addis Ababa to participate in teaching at both undergraduate and postgraduate level.

Professor Poliakoff and his colleagues wrote in Science Express: “Our collaboration has been intellectually rewarding for all of those involved and it has been particularly helpful in developing the careers of the younger participants. However, this was only possible because our Ethiopian colleagues had already built a strong chemistry department at their university.

“Having overseas scientists to champion their work on the international scene has clearly been valuable to the chemists in Ethiopia.

“We strongly urge other scientists to consider championing an African country so that their needs can be more loudly articulated in the international arena and their scientists empowered to meet the tremendous challenges of the future.”

Notes to editors: The University of Nottingham is Britain's University of the Year (The Times Higher Awards 2006). It undertakes world-changing research, provides innovative teaching and a student experience of the highest quality. Ranked by Newsweek in the world's Top 75 universities, its academics have won two Nobel Prizes since 2003.

Green Chemistry: New Recipes Really Work
By Michael Schirber, Special to LiveScience

posted: 28 June 2007 10:32 am ET

Chemistry is about mixing ingredients to make a desired product, but there is almost always some bit leftover that has to be carefully disposed of. In the pharmaceutical industry, for instance, each pound of drugs comes with 25 to 100 pounds of waste—some of which poses health hazardous.

Other chemical industries are less wasteful than this. But at least 40 million tons of hazardous waste is generated in the United States each year, according to tallies by the Environmental Protection Agency (EPA) on regulated substances.

A growing movement called green chemistry aims to reduce this ecological toll by redesigning how chemical products are made. Some of these greener alternatives, like less harmful plywood and more energy-efficient cushions, are already on store shelves.

Power switch

Study says the best energy strategies to meet the world’s growing demand for electricity are green, small and local

The wisest energy strategy for the United States, and indeed other countries facing similar challenges, is to move away from their reliance on large-scale centralized coal and nuclear plants, and instead, invest in renewable energy systems and small scale decentralized generation technologies. According to Benjamin Sovacool from the Virginia Polytechnic Institute and State University, these alternative technologies are simultaneously feasible, affordable, environmentally friendly, reliable and secure. His analysis (1) and recommendations are published in Springer’s journal Policy Sciences.

The electricity sector as it currently operates is at the mercy of natural disasters, price fluctuations, terrorist attacks and blackouts. Coupled with other, more long-standing problems such as increasing levels of pollution, growing vulnerability and inefficiency of transmission and distribution networks, and rising electricity prices related to disruptions and interruptions in fuel supply, these challenges add to the need for an evaluation of alternative energy technologies.

Sovacool studies in detail the current technological composition of, and challenges faced by, the American electric utility industry. He then evaluates the broad portfolio of energy technologies available to American electricity policy makers, against five criteria: technical feasibility, cost, negative externalities (or impact on human health and the environment), reliability and security.

Sovacool’s detailed analysis shows that three other sets of technologies – energy efficiency practices (like more efficient appliances), renewable energy systems (such as generators that create electricity from sunlight, wind, and falling water), and small-scale distributed generation technologies (such as generators that produce decentralized and modular power close to its point of consumption) – appear to offer many advantages over large and centralized nuclear and fossil fueled generators.

Sovacool’s paper shows how these alternative approaches can offer policy makers solutions to curb electricity demand, minimize the risk of fuel interruptions and shortages, help improve the fragile transmission network, and reduce environmental harm. He concludes that “it is these miniature generators – not mammoth and capital-intensive nuclear and fossil fuel plants – that offer the best strategy for diversifying electrical generation in a competitive energy environment.”

Toward a new generation of “greener” consumer products
19 November 2007
Chemical & Engineering News

Consumers will have access to medicines, cosmetics, and other products that are “greener,” less expensive, and more environmentally friendly than ever before, thanks to new manufacturing processes now under development, according to an article scheduled for the Nov. 19 issue of Chemical & Engineering News, ACS’ weekly newsmagazine.

The article, by C&EN Senior Editor Stephen K. Ritter, explains that the processes use so-called supercritical carbon dioxide, a phase of carbon dioxide with both liquid and gaseous traits and that is heralded as a nontoxic replacement for conventional manufacturing solvents. Ritter notes that while supercritical carbon dioxide shows promise for carrying out greener industrial catalytic processes, it also can provide a means for replacing inefficient chemical separations.

The new processes help reduce the use of conventional organic solvents, reduce energy consumption, and reduce the loss of costly and sometimes toxic metal catalysts. These “advances may allow for greener product separations, which typically make up the bulk of the cost of industrial processes,” Ritter states.

In New York City, the incandescent lights that have adorned the Rockefeller Center Christmas tree were replaced this year with 30,000 energy-efficient bulbs; in Paris, the trees lining the Champs-Elysees are shining brighter while using less energy; and in Washington, D.C., the White House will spend less on electricity to light its tree on the lawn this season.

All these trees are now beaming with light-emitting diodes (LEDs) instead of the traditional incandescent bulbs.

'Electronic chemicals' pave the way for brighter, more energy-efficient future

Chemical & Engineering News

From solar power to computer chips to advanced lighting, new materials developed by chemists are helping consumers reap the benefits of advanced electronics, according to an article scheduled for the July 15 issue of Chemical & Engineering News. Some of these electronics will soon appear on store shelves and offices near you.

In the C&EN cover story, writers Michael McCoy, Alexander Tullo, and Jean-Francois Tremblay point out that so-called 'electronic chemicals' play key roles in today's advanced electronics but go largely unnoticed by consumers. These unsung materials, part of a multibillion dollar electronic materials market, provide improved solar panels that crank out more fossil fuel-free electricity and new computer chips that are smaller and more energy efficient than ever. These materials also fuel the development of organic light emitting diodes (OLEDs) that promise energy savings and could render today's incandescent light bulbs and fluorescent bulbs obsolete, according to the article.

But making advanced electronics comes with a steep price. Chemical companies now invest billions of dollars to build new manufacturing plants to produce raw materials for advanced electronics. Manufacturers are also spending heavily on research and development, as new electronic advances demand innovative new chemicals, the article states.

Green skies ahead: Chemists target sustainability
Chemical & Engineering News

Amid rising concerns about oil supplies, the effects of global warming, and other environmental issues, ACS' weekly newsmagazine Chemical & Engineering News is devoting nearly 40 pages of its Aug. 18 issue to the topic of sustainability — the ability to meet the needs of people today without compromising the ability of future generations to meet their own needs, all without trashing the planet — and what it means for the chemical enterprise. C&EN's package includes four essays and an editorial that describe the sweeping panorama of sustainability issues, concluding that chemists and chemistry will play key roles in finding solutions.

In C&EN's lead essay, editor-in-chief Rudy M. Baum chronicles what he argues to be a recent tipping point by which the world has shifted from talking about sustainability to gearing up to achieve it. Three other major essays examine sustainability's impact on the chemical industry, governmental activities that encourage sustainable development, and how the science of chemistry must contribute to the field in thousands of specific ways.

Baum emphasizes in the lead article that the power of chemistry, including environmentally friendly chemicals and processes, has the ability to help society exist on Earth in a sustainable way. But he cautions that this transformation won't be smooth and easy. "This is where the government enters the picture," Baum says. "People, industries, and society itself must be given incentives to change their behavior and patterns of consumption. Some of the most successful incentives are and will be economic. Others will have to take the form of regulations."
