How metal atoms can arrange themselves on an insulator
In order to produce tiny electronic memories or sensors in the future, it is essential to be able to arrange individual metal atoms on an insulating layer. Scientists at Bielefeld University's Faculty of Chemistry have now demonstrated that this is p.....»»
Making extremely thing lubricating films predictable: Extension of the Reynolds equation by a non-linear wall slip law
When an electric vehicle accelerates, the motor generates maximum forces and enormous pressures act on the gears of the electric drivetrain. Surface meets surface, metal meets metal. If there were no lubricating film to allow the gears to slide more.....»»
Metamaterials and origamic metal-organic frameworks
Origami is a paper folding process usually associated with child's play mostly to form a paper-folded crane, yet it is, as of recently a fascinating research topic. Origami-inspired materials can achieve mechanical properties that are difficult to ac.....»»
Scientists develop functional micro-arrays for efficient lithium metal anode interface
Lithium (Li) metal anodes, with the highest specific capacity (3,860 mAh g-1) and the lowest redox potential (-3.04 V vs. standard hydrogen electrode), are considered a potential alternative for the next generation high-energy-density lithium batteri.....»»
Exploring acoustic design for better, quieter prisons
Prisons are typically noisy environments, filled with clanking metal bars and echoing concrete surfaces. This level of constant noise is harmful to both prisoners and staff, but there are few guidelines for designing better, quieter facilities......»»
Scandinavia"s oldest known ship burial is located in mid-Norway
This summer, archaeologists and a metal detectorist conducted a small survey of Herlaugshagen, at Leka in the northern part of Trøndelag County. They found something amazing......»»
Generative model unveils secrets of material disorder
National University of Singapore (NUS) scientists have utilized generative machine learning models to explore the different methods in which atoms between adjacent crystals in a piezoelectric material, which are materials that generate a small electr.....»»
Engineers tackle hard-to-map class of materials
The properties that make materials like semiconductors so sought after result from the way their atoms are connected, and insight into these atomic configurations can help scientists design new materials or use existing materials in new, unforeseen w.....»»
New Photo Renders Show Off the Galaxy A55’s Design
It seems that Samsung's upcoming midranger will feature a metal frame on the sides with smaller bezels around the display. The post New Photo Renders Show Off the Galaxy A55’s Design appeared first on Phandroid. Just recently, we got.....»»
Shrinking particle accelerators with cold plasma and a large picnic basket
Twenty-five feet below ground, SLAC National Accelerator Laboratory scientist Spencer Gessner opens a large metal picnic basket. This is not your typical picnic basket filled with cheese, bread and fruit—it contains screws, bolts, steel tubing, and.....»»
The Universe in a lab: Testing alternate cosmology using a cloud of atoms

A novel approach for dimensional engineering of covalent organic frameworks derived carbons
Covalent organic frameworks (COFs) are a special class of materials composed of interconnected organic building blocks held together by strong chemical bonds. Featured with evenly distributed atoms and abundant internal empty space, COFs can be utili.....»»
Engineering non-precious metal electrocatalysts for cost-effective and environmentally responsible water splitting
There is an ever-present struggle to reduce carbon-based energy sources and replace them with low or no-carbon alternatives. The process of splitting water could be the resolution......»»
US to replace all lead water lines within 10 years
President Joe Biden's administration on Thursday announced it would require the removal of the nation's remaining lead pipes within a decade, preventing an estimated 22 million people from potential exposure to the toxic metal in their drinking water.....»»
Agronomists save tomatoes from toxic aluminum with melatonin
RUDN University agronomists and colleagues from China and Iran have helped tomatoes cope with the toxic effect of aluminum in acidic soils with the help of melatonin. This hormone contributes to nitric oxide production, blocking the toxic metal and p.....»»
Scientists propose new method to search for deviations from the Standard Model of physics
In the search for new particles and forces in nature, physicists are on the hunt for behaviors within atoms and molecules that are forbidden by the tried-and-true Standard Model of particle physics. Any deviations from this model could indicate what.....»»
A close look at changes to the skin biome after ear piercing
A team of microbiologists at McGill University's Redpath Museum, working with a colleague at Tattoo Lounge MTL, has investigated changes to the skin microbiome when a person has an ear pierced and a metal object inserted into the puncture. In their s.....»»
High-valence metal-doped amorphous IrOx as stable electrocatalyst for acidic oxygen evolution reaction
Hydrogen has been regarded as a potential energy carrier instead of fossil fuels, addressing energy demand and environmental issues. Proton exchange membrane water electrolysis (PEMWE), with its high energy density, elevated hydrogen purity, and rapi.....»»
The "jigglings and wigglings of atoms" reveal key aspects of COVID-19 virulence evolution
Richard Feynman famously stated, "Everything that living things do can be understood in terms of the jigglings and wigglings of atoms." This week, Nature Nanotechnology features a study that sheds new light on the evolution of the coronavirus and its.....»»
The formation of an excitonic Mott insulator state in a moiré superlattice
When a negatively charged electron and a positively charged hole in a pair remain bound together following excitation by light, they produce states known as excitons. These states can influence the optical properties of materials, in turn enabling th.....»»
