Creating patterns spontaneously in synthetic materials
Nature produces a startling array of patterned materials, from the sensitive ridges on a person's fingertip to a cheetah's camouflaging spots. Although nature's patterns arise spontaneously during development, creating patterns on synthetic materials.....»»
Gibbon dances provide model to investigate the use of gestural signals in primates
Female crested gibbons display jerky, almost geometric patterns of movement. Researchers from Heinrich Heine University Düsseldorf (HHU), Oslo in Norway and Paris have studied these conspicuous movements, which are comparable to human dances......»»
Finely regulated luminescent Ag-In-Ga-S quantum dots with green-red dual emission toward white LEDs
Semiconductor quantum dots (QDs) materials have shown great potential for applications in lighting and display fields due to their wide color gamut, adjustable emission wavelength, high quantum efficiency, high color saturation, and low processing co.....»»
Engineering perovskite materials at the atomic level paves way for new lasers, LEDs
Researchers have developed and demonstrated a technique that allows them to engineer a class of materials called layered hybrid perovskites (LHPs) down to the atomic level, which dictates precisely how the materials convert electrical charge into lig.....»»
Researchers create a three-dimensional multi-focus laser for glass micro-sculpting
Glass materials are widely used in optical and optoelectronic devices due to their low cost and excellent mechanical and optical properties. Among them, glass concave/convex linear structures with feature sizes ranging from several micrometers to hun.....»»
Scientists use light to visualize magnetic domains in quantum materials
When something draws us in like a magnet, we take a closer look. When magnets draw in physicists, they take a quantum look. Scientists from Osaka Metropolitan University and the University of Tokyo have successfully used light to visualize tiny magne.....»»
First ever visualization shows photoexcited charges traveling across the interface of two semiconductor materials
UC Santa Barbara researchers have achieved the first-ever "movie" of electric charges traveling across the interface of two different semiconductor materials. Using scanning ultrafast electron (SUEM) techniques developed in the Bolin Liao lab, the re.....»»
Physicists reveal nonlinear transport induced by quantum geometry in planar altermagnets
In recent years, many physicists and materials scientists have been studying a newly uncovered class of magnetic materials known as altermagnets. These materials exhibit a unique type of magnetism that differs from both conventional ferromagnetism an.....»»

Claustrophobic cells slow their own growth, forming beautiful patterns of concentric circles
Like so many organisms on the planet, when cells experience mosh-pit-level crowding, they may just become stressed. Yet unlike most other life forms, cells subject to physical stress from crowding by neighbors can find some relief by dramatically slo.....»»
Windows 11 is creating an ‘undeletable’ 8.63GB cache
The undeletable cache issue stems from the 'checkpoint update' system, a feature designed to download smaller, incremental patches instead of full updates......»»
Uncrackable: Scorpions and sponges inspire sustainable design
Humans are by no means alone in the search for more sustainable materials. Nature, too, has been "working" on the problem of sustainability, and it's been at it for a great deal longer. Researchers at the Weizmann Institute of Science show how design.....»»
Theoretical study demonstrates existence of giant photocaloric effects in ferroelectric perovskites
Solid-state cooling is a promising alternative cooling technique that does not rely on the use of gases or liquids, like conventional refrigeration systems, but instead utilizes the properties of solid materials to refrigerate. This alternative cooli.....»»
Widening talent pool in cyber with on-demand contractors
Filling roles within the cyber sector is an ongoing battle. The shortfall of workers risks creating a vicious cycle within existing cyber teams: With fewer team members to spread the workload on, you risk burning out security professionals. Many make.....»»
Microplastic-free carrier system for pesticides shows potential for sustainable agriculture
Researchers from the University of Twente (Netherlands) and Bayreuth (Germany) have developed microplastic-free encapsulation for crop protection agents. They recently published their findings in Advanced Materials.....»»
