Does Water Always Completely Wet Water?
2014-07-16 03:09:31

Science China Press The molecular scale behavior of water at a solid/liquid interface holds fundamental significance in a diverse set of technical and scientific contexts, ranging from the efficiency of oil mining to the activity of biological molecules. Recently, it has become recognized that both the physical interactions and the surface morphology have significant impact on the behavior of interfacial water, including the water structures and wetting properties of the surface. In a...

New Semiconductor Has Promise For 2D Physics And Electronics
2014-03-21 16:13:43

Lynn Yarris, Berkeley Lab From super-lubricants, to solar cells, to the fledgling technology of valleytronics, there is much to be excited about with the discovery of a unique new two-dimensional semiconductor, rhenium disulfide, by researchers at Berkeley Lab’s Molecular Foundry. Rhenium disulfide, unlike molybdenum disulfide and other dichalcogenides, behaves electronically as if it were a 2D monolayer even as a 3D bulk material. This not only opens the door to 2D electronic...

Researchers from North Carolina State University have investigated the viability of a technique called "spincasting" for creating thin films of nanoparticles on an underlying substrate "“ an important step in the creation of materials with a variety of uses, from optics to electronics. Spincasting, which utilizes centrifugal force to distribute a liquid onto a solid substrate, already has a variety of uses. For example, it is used in the electronics industry to deposit organic thin...

Toward intelligent and creative computers Information processing circuits in digital computers are static. In our brains, information processing circuits"”neurons"”evolve continuously to solve complex problems. Now, an international research team from Japan and Michigan Technological University has created a similar process of circuit evolution in an organic molecular layer that can solve complex problems. This is the first time a brain-like "evolutionary circuit" has been...

Engineers at the University of Leeds have developed a simple technology which can be used in existing chemical reactors to ensure "right first time" drug crystal formation. Ensuring drug crystals are formed correctly is crucial to their efficacy and the efficiency of pharmaceutical manufacturers' operations. Using self-assembled monolayers, the team has been able to show that crystals form into their desired product form with the correct shape and particle structure, without the usual...

An international team of researchers from the Netherlands, Russia and Austria discovered that monolayer coverage and channel length set the mobility in self-assembled monolayer field-effect transistors (SAMFETs). This opens the door to extremely sensitive chemical sensors that can be produced in a cost-effective way. The research was done at Philips Research Eindhoven and Eindhoven University of Technology. The findings were published as an Advanced Online Publication in Nature...

U.S. scientists say they have found a way to control the geometry and stability of a new family of self-assembled-monolayer materials called carboranes. The Pennsylvania State University researchers said the exceptionally high quality and simplicity of the improved carboranes opens up new capabilities in selective patterning and control, and new possibilities for applications. They said a tailored carborane film just one-nanometer or two-nanometers in height completely changes the chemical,...

By Anglin, Timothy C Conboy, John C ABSTRACT The dependence of 1,2-dipalmitoyl-sn-glycero-3- phosphocholine (DPPC) flip-flop kinetics on the lateral membrane pressure in a phospholipid bilayer was investigated by sum- frequency vibrational spectroscopy. Planar-supported lipid bilayers were prepared on fused silica supports using the Langmuir-Blodgett/ Langmuir-Schaeffer technique, which allows precise control over the lateral surface pressure and packing density of the membrane. The lipid...

Researchers at the National Institute of Standards and Technology (NIST) have shown for the first time that a single layer of molecular "salve" can significantly soothe the stresses affecting clean metal surfaces. The discovery, revealed in a new paper,* may help scientists to understand the factors that influence surface stress, which is important in a broad array of applications from chemical and biological sensors to semiconductor manufacturing and metal plating. Because the atoms on a...
