Physicists master unexplored electron property
Physicists have demonstrated how to manipulate the 'valley' property of electrons using light by placing two-dimensional semiconductors in a light trapping structure called microcavity.
Molecular microscopy illuminates molecular motor motion
To understand how motors work on a nanoscale and millisecond scale, researchers need to see how the motors are walking.
Smart surface enables advanced manipulation of droplets
Researchers have developed an inexpensive, scalable smart surface that is powered by just a conventional electric battery. The copper-based surface changes from being highly water-repellent (superhydrophobic) to highly water-absorbent (superhydrophilic) as electric potential is applied.
New research reveals potential for synthetic materials systems that can 'count' and sense their size
Researchers have utilized computational modeling to mimic natural systems' quorum sensing behavior in synthetic materials, which could lead to devices with the ability for self-recognition and self-regulation.
When shallow defects align, diamonds shine for unprecedented quantum sensitivity
Researchers demonstrate a new way to produce high-density clusters of aligned quantum sensors in diamond just nanometers from the surface, offering submolecular sensitivity to microscopy like never before.
New phase change mechanism could lead to new class of chemical vapor sensors
An interdisciplinary team of scientists demonstrated that monolayer 2D Transition Metal Dichalcogenides undergo a change from semiconductor-to-metallic phase when exposed to airborne chemical vapors.
Nanoparticles loaded with curcumin kill cancer cells
Curcumin formula shows promise against treatment-resistant childhood cancer.
Chemical route towards electronic devices in graphene
A research team produced their electronic graphene structures through a chemical reaction. They evaporated the precursor molecules onto a gold crystal, where they react in a very controlled way to yield new chemical compounds.
Carbon nanotubes stand at attention
Just as members of a marching band align themselves for a performance, carbon nanotubes create a similar configuration.
Natural molecule to boost the performance of electrodes for rechargeable batteries
Lab tests show that a novel material based on the organic porphyrin molecule allows to charge batteries within one single minute.
Flexible proximity sensor creates smart surfaces
Researchers have developed a proximity sensor made from silicone and carbon nanotubes, which detects objects and determines their position.
Large single-crystal graphene is possible
The target of large, cheap and quick graphene synthesis achieved: 5 x 50 cm?2 and beyond.
New strategy to design mechano-responsive luminescent materials
Researchers have designed a novel mechano-responsive luminescent material using a gold and isocyanide complex, which includes two bonded rings of carbon and hydrogen atoms.
