Layered nanocomposites containing tiny structures mixed into a polymer matrix are gaining commercial use, but their complex nature can hide defects that affect performance. Now researchers have developed a system capable of detecting such defects using a Kelvin probe scanning method with an atomic force microscope.
Researchers describe a method capable of mimicking Nature's ability to sort, capture, transport and release molecules. The technique sets the stage for continuous and efficient manipulation of a broad range of molecules of relevance to human and environmental health.
Squid are the ultimate camouflage artists, blending almost flawlessly with their backgrounds so that unsuspecting prey can't detect them. Using a protein that's key to this process, scientists have designed 'invisibility stickers' that could one day help soldiers disguise themselves, even when sought by enemies with tough-to-fool infrared cameras.
No matter what the wireless standard, signal processing could not be done without the filtering of frequencies. Micro-acoustic piezoelectric resonators are the dominant technology in the market for this purpose. Theory predicts excellent oscillation characteristics for these resonators, if the electrode used for the excitation of the oscillation becomes very light. And the lightest conceivable electrode is electrically conductive graphene.
Researchers have shown how to convert waste packing peanuts into high-performance nanocarbon electrodes for rechargeable lithium-ion batteries that outperform conventional graphite electrodes, representing an environmentally friendly approach to reuse the waste.
Nanotechnology will be a major focus for NIOSH at the SOT annual meeting. NIOSH researchers will give more than 30 presentations about the latest science addressing the potential hazards of nanomaterials.
