Traditional methods for understanding catalyzed reaction kinetics typically require many chemical reactions run under artificially high concentrations of various reaction components. Reaction Progress Kinetic Analysis (RPKA), on the other hand, can provide similarly useful information using simple graphical depictions for significantly faster optimization and more cost-effective research and scale-up. (PRWEB) September 08, 2014 METTLER TOLEDO is pleased to present a new, on-demand webinar...

Researchers Show Evidence Of Common Mineral Capable Of Making, Breaking Bonds
2014-07-30 03:37:00

Arizona State University ASU team shows evidence for one mineral affecting the most fundamental process in organic chemistry: Carbon-hydrogen bond breaking and making Reactions among minerals and organic compounds in hydrothermal environments are critical components of the Earth's deep carbon cycle, they provide energy for the deep biosphere, and may have implications for the origins of life. However, very little is known about how minerals influence organic reactions. A team of...

Rare Chemical Phenomenon To Harvest Solar Energy Demonstrated By Scientists
2014-06-03 03:57:10

National University of Singapore Landmark study opens doors to further studies into chemical modification of materials for alternative energy conversion A team of international scientists led by Professor Jagadese J Vittal of the Department of Chemistry at the National University of Singapore's (NUS) Faculty of Science has successfully unraveled the chemical reaction responsible for propelling microscopic crystals to leap distances up to hundreds of times their own size when they are...

When chemist Tehshik Yoon looks out his office window, he sees a source of energy to drive chemical reactions. Plants “learned” to synthesize chemicals with sunlight eons ago; Yoon came to the field a bit more recently. But this week, in the journal Science, he and three collaborators detail a way to use sunlight and two catalysts to create molecules that are difficult to make with conventional techniques — a finding that may eventually have implications for drug making and materials...

Chemiscope To Help Chemistry In Action
2014-03-18 05:09:00

redOrbit Staff & Wire Reports - Your Universe Online Researchers at the University of California, Irvine’s Center for Chemistry at the Space-Time Limit (CaSTL) have reportedly developed a new tool that could make it possible to observe the making and breaking of chemical bonds and how molecules behave during a chemical reaction. The device is known as the “chemiscope,” and according to CaSTL officials it could revolutionize chemistry in much the same way that the microscope...

Artificial Leaf Jumps Developmental Hurdle
2014-02-19 13:11:38

Arizona State University In a recent early online edition of Nature Chemistry, ASU scientists, along with colleagues at Argonne National Laboratory, have reported advances toward perfecting a functional artificial leaf. Designing an artificial leaf that uses solar energy to convert water cheaply and efficiently into hydrogen and oxygen is one of the goals of BISfuel – the Energy Frontier Research Center, funded by the Department of Energy, in the Department of Chemistry and...

Synthetic Gasoline Production Made Easier

redOrbit Staff & Wire Reports - Your Universe Online Researchers have reportedly developed a novel chemical system that uses inexpensive and easy-to-fabricate carbon-based nanofiber materials that could prove promising in the development of synthetic gasoline. Writing in the online edition of the journal Nature Communications, University of Illinois at Chicago (UIC) mechanical and industrial engineering professor Amin Salehi-Khojin and his colleagues report that their system...

Researchers Shed New Light On Solar Water-splitting Process
2013-12-02 17:11:15

University of Oregon With the help of a new method called "dual-electrode photoelectrochemistry," University of Oregon scientists have provided new insight into how solar water-splitting cells work. An important and overlooked parameter, they report, is the ion-permeability of electrocatalysts used in water-splitting devices. Their discovery could help replace a trial-and-error approach to paring electrocatalysts with semiconductors with an efficient method for using sunlight to...

Plasma-assisted combustion could help make jets fly higher, faster and longer, according to work presented at APS Division of Fluid Dynamics Meeting Mix together air, fuel, and heat and you get combustion, the chemical reaction that powers most engines in planes, trains and automobiles. And if you throw in some ionized gas (plasma), it turns out, you can sustain combustion even in conditions that would otherwise snuff out the reaction: at low air pressure, in high winds or when there's low...

University of California - Los Angeles UCLA chemists for the first time have employed magnetic resonance imaging (MRI) — a technique normally reserved for medical clinicians peering inside the human body — to better measure the temperature of gases inside a catalytic reactor. The research, a major step toward bridging the gap between laboratory studies and industrial catalysis, could help improve the design and environmental impact of catalytic reactors, including tiny...

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...
