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.
Physicists observed the shape of a strange phenomenon that interferes with high-temperature superconductivity called charge ordering, discovering that it is stripy, not checkered, and settling a long-standing debate in the field.
Progress in developing nanophotonic devices capable of withstanding high temperatures and harsh conditions for applications including data storage, sensing, health care and energy will depend on the research community and industry adopting new 'plasmonic ceramic' materials.
The latest breakthrough answers a key question on the microscopic electronic structure of cuprate superconductors, the most celebrated material family in our quest for true room-temperature superconductivity.
A device resembling a plastic honeycomb yet infinitely smaller than a bee's stinger can steer light beams around tighter curves than ever before possible, while keeping the integrity and intensity of the beam intact.
