UA scientists have inserted metal atoms into methane gas molecules -- a potential advancement for industrial hydrocarbon chemistry and our understanding of how nature uses metals in the molecules of living organisms For the first time, chemists have succeeded in plugging a metal atom into a methane gas molecule, thereby creating a new compound that could be a key in opening up new production processes for the chemical industry, especially for the synthesis of organic compounds, which in turn...

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...

Mechanical engineering at the molecular level In the nanoworld many things are different. Scientists only recently started unveiling and harnessing the underlying laws and principles. A team associated with Professor Johannes Barth from the Physics Department of the TU Muenchen have now succeeded in capturing rod-shaped molecules in a two-dimensional network in such a way that they autonomously form small rotors that turn in their honeycomb-like cages. Nature itself provides the role model...

Researchers at Queen's University have discovered the method for studying oxygen in large molecular systems. The findings will help in the study of proteins, DNA, RNA and other molecular structures. Biological molecules make up all living creatures on earth and contain four major elements "“ hydrogen, carbon, nitrogen and oxygen. But until now scientists were only able to use nuclear magnetic resonance (NMR) to study three out of the four elements in the molecule puzzle because oxygen...

(Ivanhoe Newswire) -- Just when we think we have administering medications down to a science, researchers have discovered a new method that could one day be more effective than methods used today. Researchers at Queen's University have discovered how molecules in glass or plastic are able to move when exposed to light from a laser. This method could one day be used to facilitate medicinal drug distribution by allowing doctors to control the rate and amount at which the drugs are given. ...

Researchers at Queen's University have discovered how molecules in glass or plastic are able to move when exposed to light from a laser. The findings could one day be used to facilitate medicinal drug distribution by allowing doctors to control the time and rate at which drugs are delivered into the body. The drugs, in a solid plastic carrier, could be released through the body when exposed to light. Lead researcher Jean-Michel Nunzi, a professor in the departments of Chemistry and Physics,...

UCLA physicists have taken a significant step in controlling chemical reactions mechanically, an important advance in nanotechnology, UCLA physics professor Giovanni Zocchi and colleagues report. Chemical reactions in the cell are catalyzed by enzymes, which are protein molecules that speed up reactions. Each protein catalyzes a specific reaction. In a chemical reaction, two molecules collide and exchange atoms; the enzyme is the third party, the "midwife to the reaction." But the...

The development of new organic batteries"”lightweight energy storage devices that work without the need for toxic heavy metals"”has a brighter future now that chemists have discovered a new way to pass electrons back and forth between two molecules. The research is also a necessary step toward creating artificial photosynthesis, where fuel could be generated directly from the sun, much as plants do. University of Texas at Austin chemists Christopher Bielawski and Jonathan Sessler...

UC Riverside chemists study quadrupedal molecular machines to provide an answerMolecular machines can be found everywhere in nature, for example, transporting proteins through cells and aiding metabolism. To develop artificial molecular machines, scientists need to understand the rules that govern mechanics at the molecular or nanometer scale (a nanometer is a billionth of a meter).To address this challenge, a research team at the University of California, Riverside studied a class of...

Researchers at the California Institute of Technology (Caltech) have devised a new technique"”using a sheet of carbon just one atom thick"”to visualize the structure of molecules. The technique, which was used to obtain the first direct images of how water coats surfaces at room temperature, can also be used to image a potentially unlimited number of other molecules, including antibodies and other biomolecules.A paper describing the method and the studies of water layers appears...
