Texas Advanced Computing Center, The University of Texas at Austin In a well-known fairy tale, Rumpelstiltskin used magic to weave straw into gold. Today, scientists are reversing that formula – using gold to turn straw (and other forms of biomass) into today's global currency: energy. The magic involves a special nanocatalyst, in which minute particles of gold dot the surface of titanium-oxide. The forces that emerge from the combination of these two materials are strong enough...

X-rays Help Understand How Mechanical Action May Lead To Greener Chemistry

European Synchrotron Radiation Facility Solvents are omnipresent in the chemical industry, and are a major environmental and safety concern. Therefore the large interest in mechanochemistry: an energy-efficient alternative that avoids using bulk solvents and uses high-frequency milling to drive reactions. Milling is achieved by the intense impact of steel balls in a rapidly moving jar, which hinders the direct observation of underlying chemistry. Scientists have now for the first time...

Pharmaceuticals Go Green

Alan McStravick for redOrbit.com — Your Universe Online It seems even the pharmaceutical industry is getting on the ℠go green´ bandwagon. Researchers from the University of Gothenburg in Sweden are finding that there is a more ecologically prudent manner for the production of pharmaceuticals. When labs are producing pharmaceuticals, they do so through a series of chemical reactions. These reactions require a catalyst to occur. Chemically speaking, a catalyst is a...

Electrons Frozen In Flight

Using the world´s fastest laser pulses, which can freeze the ultrafast motion of electrons and atoms, UA physicists have caught the action of molecules breaking apart and electrons getting knocked out of atoms. Their research helps us better understand molecular processes and ultimately be able to control them in many possible applications. In 1878, a now iconic series of photographs instantly solved a long-standing mystery: Does a galloping horse touch the ground at all times? (It...

Best Of Both Catalytic Worlds

Berkeley Lab Researchers Develop New Technique for Heterogenizing Homogenous Nano Catalysts Catalysts are substances that speed up the rates of chemical reactions without themselves being chemically changed. Industrial catalysts come in two main types — heterogeneous, in which the catalyst is in a different phase from the reactants; and homogeneous, in which catalyst and the reactants are in the same phase. Heterogeneous catalysts are valued for their sustainability because they can...

Giant network links all known compounds and reactions to create chemical Google on steroids Northwestern University scientists have connected 250 years of organic chemical knowledge into one giant computer network -- a chemical Google on steroids. This "immortal chemist" will never retire and take away its knowledge but instead will continue to learn, grow and share. A decade in the making, the software optimizes syntheses of drug molecules and other important compounds, combines long...

Material wastes energy, Case Western Reserve University researcher suggests Fuel cells are inefficient because the catalyst most commonly used to convert chemical energy to electricity is made of the wrong material, a researcher at Case Western Reserve University argues. Rather than continue the futile effort to tweak that material - platinum - to make it work better, Chemistry Professor Alfred Anderson urges his colleagues to start anew. "Using platinum is like putting a resistor in...

Diels and Alder won the Nobel; now UCLA's Kendall Houk makes the movie In 1928, chemists Otto Diels and Kurt Alder first documented diene synthesis, a chemical reaction important for synthesizing many polymers, alkaloids and steroids. Their work on this mechanism, which came to be known as the Diels—Alder reaction, won them the 1950 Nobel Prize in chemistry. Since then, the iconic reaction has become the most commonly used and studied mechanism in organic chemistry. But what...

A team of researchers at the California Institute of Technology (Caltech) has devised a new method for making complex molecules. The reaction they have come up with should enable chemists to synthesize new varieties of a whole subclass of organic compounds called nitrogen-containing heterocycles, thus opening up new avenues for the development of novel pharmaceuticals and natural products ranging from chemotherapeutic compounds to bioactive plant materials such as morphine. The...

Chemistry is a physical science concerned with the composition, structure, and properties of matter. It also deals with the changes that matter undergoes during chemical reactions. It incorporates the studies of various atoms, molecules, crystals and other aggregates which can be combined or isolated and concepts of energy and entropy through which chemical processes occur. Modern chemistry (from the Egyptian kēme, meaning "earth") evolved from alchemy following the chemical revolution...
