Two-dimensional carbon layers, so-called graphenes, are regarded as a possible substitute for silicon in the semiconductor industry. The electronic properties of these layers can be varied by "building in" specific arrays of holes in their structure.
Vibrations in nanostructures offer applications in molecular-scale biological sensing and ultrasensitive mass detection. To approach single-atom sensing, it is necessary to reduce the dimensions of the structures to the nanometer scale while preserving long-lived vibrations.
New nanoscale materials and devices are required to replace the silicon transistor that's at the heart of today's semiconductors, but to build these new devices, researchers will have to be able to measure the thickness - if that's the right word - of layers consisting of only a few atoms, according to a UT Dallas researcher.
PI (Physik Instrumente) L.P. -- the inventor of Piezo-Z focusing systems—has added two new multi-axis stages for super-resolution microscopy applications, providing highly accurate motion with sub-nanometer resolution over travel ranges of 200 µm in XY and XYZ.
Just as fly paper captures insects, an innovative new device with nano-sized features developed by researchers at UCLA is able to grab cancer cells in the blood that have broken off from a tumor.
Sulfate groups are crucial building blocks for many molecules but are difficult to handle. Dutch researcher Martijn Huibers has discovered how sulfate groups can be protected during the construction of a molecule. Thanks...
A recent experiment at the Department of Energy's Thomas Jefferson National Accelerator Facility has found that a proton's nearest neighbors in the nucleus of the atom may modify the proton's internal structu...
Oxford Instruments Plasma Technology (OIPT) has recently won a contract with French research centre, STnano in Strasbourg, France for the supply of a Plasmalab® System80 Plus ICP system.
The goal of an integrated, miniaturized laboratory analysis system, also known as a "lab-on-a-chip," is simple: sample in, answer out. However, researchers wanting to use these microfluidic devices to analyze complex solutions containing particulates or other contaminating materials often find that the first part of the process isn't so easy.
To exploit the quantum world to the fullest, a key commodity is entanglement-the spooky, distance-defying link that can form between objects such as atoms even when they are completely shielded from one another.
