Cherned up to the maximum

NanoWerk.com - Sat, 07/11/2020 - 13:11
In topological materials, electrons can display behaviour that is fundamentally different from that in 'conventional' matter, and the magnitude of many such 'exotic' phenomena is directly proportional to an entity known as the Chern number. New experiments establish for the first time that the theoretically predicted maximum Chern number can be reached in a real material.

Liquid crystals create easy-to-read, color-changing sensors

NanoWerk.com - Sat, 07/11/2020 - 13:01
Chameleons are famous for their color-changing abilities. Depending on their body temperature or mood, their nervous system directs skin tissue that contains nanocrystals to expand or contract, changing how the nanocrystals reflect light and turning the reptile's skin a rainbow of colors. Inspired by this, scientists have developed a way to stretch and strain liquid crystals to generate different colors.

Invention: 'Nanocage' tool untangles (molecular) spaghetti

ScienceDaily.com: Nanotechnology News - Fri, 07/10/2020 - 21:15
Scientists have invented a new tool -- they call it a ''nanocage'' -- that can catch and straighten out molecule-sized tangles of polymers - -whether made of protein or plastic. This tool -- that works a bit like pulling a wad of thread through a needle hole -- opens a new way to create custom materials that have never been made before.

Microscopy technique reveals nanoscale detail of coatings as they dry

ScienceDaily.com: Nanotechnology News - Fri, 07/10/2020 - 20:18
Thin film coatings do more than add color to walls. For example, they can be used as pharmaceutical devices. How these coatings dry can change their properties, which is especially important for films used in drug delivery. Engineering researchers studying the in situ drying behavior of thin film coatings are visualizing particle interactions with groundbreaking precision. Their findings could impact the development of drug delivery technology.

Highly sensitive plasmonic metasensors based on atomically thin perovskite

NanoWerk.com - Fri, 07/10/2020 - 14:25
Researchers have designed and fabricated an ultrasensitive plasmonic biosensor with the integration of atomically thin perovskite nanomaterials on metasurfaces. For that purpose, they used an atomically thin perovskite nanomaterial with high absorption rate, sandwiched between hexagonal boron nitride and graphene layers, which enables the precise tuning of the depth of the plasmonic resonance dip. This biosensor can reach an ultra-high plasmonic sensitivity for detecting small-molecule, low-concentration analytes.

Magnetic memory states go exponential

ScienceDaily.com: Nanotechnology News - Fri, 07/10/2020 - 01:28
Researchers showed that relatively simple structures can support exponential number of magnetic states -- much greater than previously thought -- and demonstrated switching between the states by generating spin currents. The ability to stabilize and control exponential number of discrete magnetic states in a relatively simple structure constitutes a major contribution to spintronics and may pave the way to multi-level magnetic memory with extremely large number of states per cell, be used for neuromorphic computing, and more.
