Ancient geology helps explain why Australia holds some of world's richest gold
Ancient geology helps explain why Australia holds some of world's richest gold
Gold has long held a special place in Australia's history, shaping the nation's economic fortunes and driving waves of migration since the 1850s gold rushes. Today, Australia stands as one of the world's largest gold producers, with the precious metal a key driver of both regiona
New insight into how cells move copper out of the mitochondrial matrix could guide novel t
Copper is essential for life. Our cells need the metal to make energy and stay healthy, but if it is in the wrong place or present in excess, copper can be deadly. Texas A&M AgriLife Research scientists have identified a key protein that helps maintain copper balance, with implic
Novel rice paddy approach aims to prevent toxic metals from tainting rice
In a perspective published in Nature Reviews Earth & Environment, Colorado State University researchers describe a management approach to prevent the uptake of arsenic, cadmium and mercury in rice grains to protect human health. They propose strategies that would change soil chem
Scientists develop predictive roadmap to boost performance in next-gen spintronics
Scientists develop predictive roadmap to boost performance in next-gen spintronics
Chiral 2D metal halide perovskites (MHPs) are among the most promising materials for future technologies that exploit the spin of electrons in spin-based optoelectronics, or spintronics, but getting them to perform consistently has proven difficult. Now scientists at Lawrence Ber

Metal hydride molecule trapped with laser light opens path to ultracold hydrogen
Controlling and trapping molecules, units of a substance consisting of two or more chemically bound atoms, with laser light is significantly more challenging than trapping individual atoms. This is because molecules exhibit more complex vibrational and rotational dynamics that ma
How atomic defects can program carbon quantum dots for future light-based technologies
How atomic defects can program carbon quantum dots for future light-based technologies
Carbon quantum dots (CQDs) are tiny carbon-based nanomaterials that have attracted increasing attention as environmentally friendly alternatives to conventional heavy-metal quantum dots. They are lightweight, photostable and potentially biocompatible, and their light absorption a

Plasma and graphene combine to protect metal surfaces from corrosion
Plasma is an ionized gas, often referred to as the fourth state of matter. Plasmas, which are created artificially by applying energy to a gas, are found in the fluorescent tubes that illuminate kitchens. However, they have many other possible applications, such as the production

Nanopattern method unlocks precise control of disorder for wave-guiding devices
A research team has developed a methodology to precisely design and control the "degree of disorder" in nanopattern arrays using metal-infiltrated block copolymer (BCP) thin films. The work was led by Professor So Youn Kim of the Seoul National University College of Engineering D
One‑step process generates high entropy alloy nanoparticles in milliseconds for catalyst c
A University at Buffalo-led team of researchers has developed a method for producing advanced nanoparticles that could accelerate the discovery of new materials for energy and electronic applications. The study, published in Nature Communications, introduces a one-step process th
MOF thin films reveal hidden dense packing, challenging decades of porous assumptions
Due to their high porosity, metal-organic frameworks (MOFs) are regarded as promising materials for innovative applications, which is why the Nobel Prize in Chemistry was awarded in 2025 for their discovery. They are used, for example, to store gases, to capture CO2 and for the t
Metallic effect pigments significantly reduce flow-line visibility on glossy plastic surfa
Metallic effects on plastic surfaces have become standard in many industries, from automotive interiors and exteriors to toys and household appliances. However, injection-molded parts with metallic effects suffer from a well-known drawback: visible flow lines that appear as strea

Electrical imbalances at grain boundaries help explain solid-state battery failure
Next-generation batteries that use new electrolyte materials could achieve far higher energy density than today's lithium-ion batteries, without many of the safety concerns. But advanced batteries, such as those that use solid or almost-solid electrolytes, have been plagued by th
