Shape memory achieved for nano-sized objects
For the first time, ETH Zurich researchers have produced objects with shape memory that are only twenty nanometres thick. Credit: ETH Zurich / Minsoo Kim Alloys that can return to their original structure after being deformed have a so-called shape memory. This phenomenon and the resulting forces are used in many mechanical actuating systems, for…

New kind of transistor could shrink communications devices on smartphones
One month after announcing a ferroelectric semiconductor at the nanoscale thinness required for modern computing components, a team has now demonstrated a reconfigurable transistor using that material. Their work paves the way for single amplifiers that can do the work of multiple conventional amplifiers, among other possibilities. Continue Reading News Source: www.sciencedaily.com

Researchers create world’s first energy-saving paint—inspired by butterflies
Structural absorption for color generation. (A) Many chemical substances produce color by selectively absorbing frequencies matching their molecular electronic transitions. Pink color in Formosa azaleas is due to the absorption of cyaniding molecules. (B) An example of structural coloration is found in the Peruvian Morpho didius. Lamella nanostructures found in its wings scatter the blue…

Cyborg technology analyzes the functional maturation of stem-cell derived heart tissue
The nanoelectronic sensors (yellow, blue) are embedded with natural tissues (red, green). Credit: Liu Lab, Harvard SEAS Research in animal models has demonstrated that stem-cell derived heart tissues have promising potential for therapeutic applications to treat cardiac disease. But before such therapies are viable and safe for use in humans, scientists must first precisely understand…

Two Oddball Ideas for a Megaqubit Quantum Computer
The perpetual problem with scaling up most quantum computers is a seemingly mundane one—too many cables. Experts say quantum computers might need at least a million qubits kept at near absolute zero to do anything computationally noteworthy. But connecting them all by coaxial cable to control and readout electronics, which work at room temperature, would…

How the EU Chips Act Could Build “Innovation Capacity” in Europe
The European Commission wants Europe to boost its share of global semiconductor production to 20 percent by 2030, from 10 percent today. To that end, it is forwarding plans for more than €43 billion in public and private investment through a European Chips Act. To accomplish that increase in chip capacity, the legislation will approve…

Super-resolution in ultrafast scattering
Mar 08, 2023 (Nanowerk Spotlight) The Nobel Prize in Chemistry in 2014 was a recognition of the groundbreaking advancements made in the field of super-resolved fluorescence microscopy. The prestigious award was jointly presented to Eric Betzig, Stefan Hell, and William Moerner for their contributions to surpassing the physical limitations of light microscopes, which were once…

Physicists found that speeding electrons trapped in circular loops in graphene quantum dots are highly sensitive to external magnetic fields — ScienceDaily
Trapped electrons traveling in circular loops at extreme speeds inside graphene quantum dots are highly sensitive to external magnetic fields and could be used as novel magnetic field sensors with unique capabilities, according to a new study. Electrons in graphene (an atomically thin form of carbon) behave as if they were massless, like photons, which…

Tubular nanomaterial of carbon makes ideal home for spinning quantum bits — ScienceDaily
Scientists find that a tubular nanomaterial of carbon makes for ideal host to keep quantum bits spinning in place for use in quantum information technologies. Scientists are vigorously competing to transform the counterintuitive discoveries about the quantum realm from a century past into technologies of the future. The building block in these technologies is the…

Scientists find new workable feature of a class of 2D materials — ScienceDaily
Rice University materials scientist Boris Yakobson and collaborators uncovered a property of ferroelectric 2D materials that could be exploited as a feature in future devices. Because they bend in response to an electrical stimulus, single-layer ferroelectric materials can be controlled to act as a nano-scale switch or even a motor, according to the study published…
