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...

University of Utah chemists find new way to design important molecules University of Utah chemists developed a method to design and test new catalysts, which are substances that speed chemical reactions and are crucial for producing energy, chemicals and industrial products. By using the new method, the chemists also made a discovery that will make it easier to design future catalysts. The discovery: the sizes and electronic properties of catalysts interact to affect how well a catalyst...

Researchers design a self-assembling material that can house other molecules Chemical reactions happen all of the time: some things burn or rust, others react to light exposure--even batteries use chemical reactions to supply electricity. One of the big challenges chemists continually face is finding new ways to control these reactions or create conditions that promote desirable reactions and limit undesirable ones. Recently, researchers at New York University demonstrated an ability to make...

UCLA nanotech research mimics enzymes in directing chemical reactions Good chemists are passive-aggressive "” they manipulate molecules without actually touching them. In a feat of manipulating substances at the nanoscale, UCLA researchers and colleagues demonstrated a method for isolating two molecules together on a substrate and controlling how those two molecules react when excited with ultraviolet light, making detailed observations both before and after the reaction. Their research...

New research at the University of North Carolina at Chapel Hill investigating the effect of temperature on extremely slow chemical reactions suggests that the time required for evolution on a warm earth is shorter than critics might expect. There has been controversy about whether life originated in a hot or cold environment, and about whether enough time has elapsed for life to have evolved to its present complexity. But new research at the University of North Carolina at Chapel Hill...

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...

  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
