A research group introduced the widest graphene nanoribbon prepared by the bottom-up approach with electrical properties surpassing those of silicon semiconductors, promising a new generation of miniaturized electronic devices.
Researchers have managed to create structures that are a complete paradox: single, continuous crystals that have multiple domains, an asymmetric shape and curved lines; they are as complex as one could expect from a 'monumental' structure.
Physicists have revealed a so-far overlooked nonlinear optical mechanism that emerges from the light-induced tunneling of electrons inside dielectrics.
Scientists present insights from sophisticated small-scale mechanical experiments explaining unexpected plastic deformation of silicon on the nanoscale.
Researchers have developed a new method of applying anti-inflammatory substances to implants in order to inhibit undesirable inflammatory reactions in the body.
Scientists have discovered details about a novel type of polarized light-matter interaction with light that literally turns end over end as it propagates from a source. Their find could help study molecules like those in light-harvesting antennas anticipated to have unique sensitivity to the phenomenon.
Physicists used X-ray measurements and analyses to show that velocity scaling and dispersion in wave transmission is based on grainy particle arrangements and chains of force between them, while reduction of wave intensity is caused mainly from grainy particle arrangements alone.
Researchers have developed a lightweight, multifunctional nanofiber material that can protect wearers from both extreme temperatures and ballistic threats.
Method could shed light on nitric oxide's role in the neural, circulatory, and immune systems.
In lab tests, virus-like DNA structures coated with viral proteins provoke a strong immune response in human B cells.
Liquid, biocompatible and micro-injectable, the new retinal prosthesis is an aqueous suspension of photoactive nanoparticles that functionally replace the photoreceptors of the retina damaged by degenerative diseases and aging.
Seeing light emerge from a nanoscale experiment didn't come as a big surprise to physicists. But it got their attention when that light was 10,000 times brighter than they expected.
Researchers developed a new imaging technique that is fast and sensitive enough to observe these elusive critical fluctuations in two-dimensional magnets. This real-time imaging allows researchers to control the fluctuations and switch magnetism via a 'passive' mechanism that could eventually lead to more energy-efficient magnetic storage devices.
Scientists have provided the first theoretical explanation for how electrical current is conducted in semiconductors made of nanocrystals. In the future, this could lead to the development of new sensors, lasers or LEDs for TV screens.
A research team developed method for trapping elusive electrons.
Novel complementary nanoelectromechanical (CNEM) switches based on complementary ferroelectric nanocracks integrate the advantages of ferroelectric and nanoelectromechanical switches, such as nonvolatility, quasi-zero OFF-state leakage current and low operating voltage. These ferroelectric crack-based CNEM switches could realize energy-efficient and high-density reconfigurable computing, which can be specialized to a particular task through its universal programmability, offering large flexibility and short time from design to realization.
Researchers are using high-resolution printing technology and the unique properties of graphene to make low-cost biosensors to monitor food safety and livestock health.
Using a supercomputer, researchers have simulated and evaluated one hundred possible materials for designing high-performance transistors and discovered 13 promising candidates.
Indium nitride is a promising material for use in electronics, but difficult to manufacture. Scientists have developed a new molecule that can be used to create high-quality indium nitride, making it possible to use it in, for example, high-frequency electronics.
A review of the scientific literature highlights the potential of hybrid materials based on cellulose nanocrystals.
