Study Finds Way To Observe Ion Responsible For Early Star Formation
2012-04-14 06:02:08

Researchers from the University of Arizona (UA) claim that they have found a way to observe the triatomic hydrogen ion believed to be the key element responsible for the formation of the first stars following the Big Bang. According to an article published to the UA News website on Wednesday, the molecule, which is known as H3+, is an ion that consists of three hydrogen atoms with just a pair of electrons to share between them, giving it a positive charge. It is believed to be the catalyst...

Some atoms don't always follow the rules. Take the beryllium dimer, a seemingly simple molecule made up of two atoms that University of Delaware physicists Krzysztof Szalewicz and Konrad Patkowski and colleague Vladimír Spirko of the Academy of Sciences of the Czech Republic report on in the Dec. 4 edition of the journal Science. Beryllium is a strong, hard, toxic metal found naturally in minerals such as emeralds and commonly used as an alloy with other metals in many...

The performance of modern electronics increases steadily on a fast pace thanks to the ongoing miniaturization of the utilized components. However, se-vere problems arise due to quantum-mechanical phenomena when conven-tional structures are simply made smaller and reach the nanometer scale. Therefore current research focuses on the so-called bottom-up approach: the engineering of functional structures with the smallest possible building blocks - single atoms and molecules. For the first time a...

Like astronomers counting stars in the familiar universe of outer space, chemists in Switzerland are reporting the latest results of a survey of chemical space "” the so-called chemical universe where tomorrow's miracle drugs may reside. The scientists conclude, based on this phase of the ongoing count, that there are 970 million chemicals suitable for study as new drugs. Scheduled for the July 1 issue of the Journal of the American Chemical Society, the study represents the largest...

The smallest mechanical switch plus an electronic switch of a type never seen before. That's how physicist Marius Trouwborst sums up the results of his PhD research on electric current through atoms and molecules. "ËœThe ultimate aim of nanotechnology is to use molecules for electronics', he says. "ËœThat aim has now come a step closer.' The enormous progress in information technology is mainly related to the fact that the electronic parts in computers are getting smaller...

By Joann Loviglio PHILADELPHIA - For anyone whose last foray into chemistry was being forced to memorize the periodic table of elements in high school, there's new reason to take another look at a subject you might have vowed never to revisit after final exams. As chemical and molecular innovations - from nylon to plastic to cosmetics - transformed modern life, genomics and nanotechnology discoveries could dramatically transform the future. The Chemical Heritage Foundation's ambitious...

COLUMBUS, Ohio -- Chemists have calculated the structure of a very unusual molecule, one whose hyperactive atoms have earned it the nickname "the scrambler." This highly caustic "protonated methane," or CH5+, is also called a "super acid," and it is a short-lived player in the chemical reactions that make petroleum products. CH5+ should also be present in interstellar clouds where stars and planets form, said Anne B. McCoy, professor of chemistry at Ohio State University. McCoy hopes that...

A major breakthrough in the use of molecules as information processors is to be announced at this year's BA Festival of Science in Dublin. Nanotechnology experts are exploring the capabilities of molecules that act like conventional computers but can operate in tiny places where no silicon-based chip or semiconductor can go. Now, for the first time, they have used these molecules to perform logic operations and process information in spaces a few nanometres across. This advance has been...

COLUMBUS , Ohio - Ohio State University physicists have obtained the first-ever experimental evidence of a particular quantum mechanical effect "“- one that was theorized a decade ago. The effect, called quantum monodromy (Greek for "once around"), relates in part to the behavior of molecules based on their atomic structure and vibrational frequencies. A better understanding of quantum monodromy could have implications in astronomy, atmospheric science, and biology. The physicists...
