Where does water end and air begin? Scientists found that some water molecules exist as both a gas and a liquid by splitting the difference between the two, according to a new study in Nature. In the uppermost layer of water, the boundary between gas and liquid occurs in one quarter of water molecules, where one hydrogen atom is in the water and the other vibrates freely above it. These molecules straddle between gas and liquid phases, says senior author Alexander Benderskii of the University...

The quantum physics of tailor-made organic macro-molecules "“ For the first time - as presented in Nature Communications - the quantum behavior of molecules consisting of more than 400 atoms was demonstrated by quantum physicists based at the University of Vienna in collaboration with chemists from Basel and Delaware. The international and interdisciplinary team of scientists thus sets a new record in the verification of the quantum properties of nanoparticles. In addition, an important...

A controversial idea that sense of smell can be explained by quantum physics is gaining traction in the science world, according to researchers. Researchers, reporting at the American Physical Society meeting in Dallas, say the key to proving how such a theory would work revolves around tiny packets of energy -- or quanta -- lost by electrons. The scientists performed experiments using tiny wires and showed that as electrons move on proteins within the nose, odor molecules could absorb...

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 method for unraveling molecular structures The team of Professor Burkhard Luy from KIT and Junior Professor Stefan F. Kirsch from the TUM has now shown for the first time that certain NMR parameters, the so-called residual dipolar couplings (RDCs), can make a significant contribution towards determining the constitution of chemical compounds when traditional methods fail. To do this they embedded molecules of the compound in a gel which slightly constricts their mobility. By stretching...

New insights from the nano world The mechanism for binding oxygen to metalloporphyrins is a vital process for oxygen-breathing organisms. Understanding how small gas molecules are chemically bound to the metal complex is also important in catalysis or the implementation of chemical sensors. When investigating these binding mechanisms, scientists use porphyrin rings with a central cobalt or iron atom. They coat a copper or silver support surface with these substances. An important...

A myriad of methods for watching water molecules in motion advances critical understanding of biology, chemistry and climate science Water (H2O) is a unique molecule that holds amazing properties. Scientists have a good grasp of the structure and chemistry of individual molecules of water. But understanding how large numbers of these molecules move and interact--within bulk liquid water, or at the interface between water and air--is much more complicated. Theoretical chemist James Skinner, at...
