3D microprinting counterfeit protection for products, passports, and money

ScienceDaily.com: Nanotechnology News - 15 ноября, 2017 - 17:24
Security features are to protect bank notes, documents, and branded products against counterfeiting. Losses caused by product forgery and counterfeiting may be enormous. Researchers now propose to use printed 3D microstructures instead of 2D structures, such as holograms, to improve counterfeit protection.

Powering a piezoelectric nanogenerator with onion skin bio waste

Nanowerk.com - 15 ноября, 2017 - 11:07
Self-powered nanotechnology based on one type of nanogenerators - piezoelectric nanogenerators - aims at powering nanodevices and nanosystems using the energy harvested from the environment in which these systems are suppose to operate. This offers a completely new approach for harvesting mechanical energy using organic and inorganic materials. Researchers have now reported a novel bio-piezoelectric nanogenerator using naturally abundant, self-aligned cellulose fibrous untreated onion skin as efficient piezoelectric material.

Butterfly wing inspires photovoltaics: Light absorption can be enhanced by up to 200 percent

ScienceDaily.com: Nanotechnology News - 14 ноября, 2017 - 17:19
Sunlight reflected by solar cells is lost as unused energy. The wings of the butterfly Pachliopta aristolochiae are drilled by nanostructures (nanoholes) that help absorbing light over a wide spectrum far better than smooth surfaces. Researchers have now succeeded in transferring these nanostructures to solar cells and, thus, enhancing their light absorption rate by up to 200 percent.

Thin-film transistors get wavy

Nanowerk.com - 14 ноября, 2017 - 11:58
For enhanced visualization experience, high resolution display technology with fast frame rate to suppress the motion blur at that resolution is essential. In modern display technologies, which are mostly active matrix display system, there are planar thin film transistors (TFTs) which enable both high resolution and fast imaging. Scaled TFTs can provide high resolution. Fast switching can be facilitated by the scaling as well as high mobility channel material. In new work, researchers have shown that both high resolution and fast frame rate display technology is possible, irrespective of the active channel material.
