Scientists at the Max Planck Institute for Polymer Research in Mainz and the National University of Singapore have attested that the thermal conductivity of graphene diverges with the size of the samples. This discovery challenges the fundamental laws of heat conduction for extended materials.
An international team of scientists discovered a new quantum control mechanism to selectively shake and break C-H bonds in symmetric hydrocarbon molecules with the waveform of femtosecond laser pulses.
A U.S. patent has been issued for a method comprising: dispersing carbon nanotubes in a solvent; and depositing the carbon nanotubes on a porous, conductive substrate; wherein the porous, conductive substrate is capable of functioning as a filter and a working electrode.
Generally, a lab-on-a-chip (LOC) can run no more than a test or two. That's because the chips are designed manually. If the LOC were made using computer-aided design, you could run dozens of tests with a single drop of blood.
Theseus was a great hero in Greek mythology known for qualities such as strength, courage and wisdom. Therefore it's no surprise that a team of Greek IBM scientists in Zurich and a professor from the University of Patras, Greece, borrowed his name as a codeword for a groundbreaking new memory technology, which combines flash with phase change memory (PCM) on a PCI-e card. Initial tests have clocked 12x and 275x improvements - and that's no myth.
Synchrotron X-rays are frequently used to image a wide range of different materials, but they can also cause chemical changes as well. In a new study, researchers looked at how a material?s electrical resistance changes when it is irradiated with these high-energy X-rays.
The Au-tipped CdSe nanorods were found to significantly increase the efficiency for charge separation and collection of energetic electrons in the Au nanoparticles, leading to an exceptional improvement in photocatalyzing multiple-electron reduction (MER) reactions, even in aerobic aqueous solutions at room temperature.
In an effort to extract a little more truth from the world of nanomaterials and nanostructures, researchers at the National Institute of Standards and Technology have built the first low-energy focused ion beam (FIB) microscope that uses a lithium ion source.
Nerve agents are among the world's most feared chemical weapons, but scientists at the National Institute of Standards and Technology have demonstrated a way to engineer carbon nanotubes to dismantle the molecules of a major class of these chemicals. In principle, they say, the nanotubes could be woven into clothing that destroys the nerve agents on contact before they reach the skin.
