Batterygate lawsuit failed in South Korea despite US win; lawyers claim unfairness
The US Batterygate lawsuit resulted in Apple agreeing to pay up to $500M to settle the case, but an equivalent case in South Korea has been dismissed – for what the plaintiff’s lawyers say are unfair reasons. Both cases relate to Apple’s decis.....»»
Study: Superconductivity switches on and off in "magic-angle" graphene
With some careful twisting and stacking, MIT physicists have revealed a new and exotic property in "magic-angle" graphene: superconductivity that can be turned on and off with an electric pulse, much like a light switch......»»
Graphene researchers discover long-term memory in 2D nanofluidic channels
A collaboration between teams from the National Graphene Institute (NGI) at The University of Manchester, and the École Normale Supérieure (ENS), Paris, demonstrated Hebbian learning in artificial nanochannels, where the channels showed short and l.....»»
Transistors repurposed as microchip "clock" address supply chain weakness
Microchip fab plants in the United States can cram billions of data processing transistors onto a tiny silicon chip, but a critical device, in essence a "clock," to time the operation of those transistors must be made separately—creating a weak poi.....»»
The world’s farms are hooked on phosphorus, and that’s a problem
Nonrenewable fertilizer powers 50% of Earth's agricultural productivity. Enlarge (credit: Brian Brown/Getty Images) Disrupting Earth’s chemical cycles brings trouble. But planet-warming carbon dioxide isn’t the only.....»»
The World’s Farms Are Hooked on Phosphorus. It’s a Problem
Half of the globe’s crop productivity comes from a key fertilizer ingredient that’s non-renewable—and literally washing away......»»
Sensing odor molecules on a graphene surface layered with self-assembled peptides
Graphene-based olfactory sensors that can detect odor molecules based on the design of peptide sequences were recently demonstrated by researchers at Tokyo Tech. The findings indicated that graphene field-effect transistors (GFETs) functionalized wit.....»»
Humans plunder the periodic table while turning blind eye to the risks of doing so, say researchers
For millions of years, nature has basically been getting by with just a few elements from the periodic table. Carbon, calcium, oxygen, hydrogen, nitrogen, phosphorus, silicon, sulfur, magnesium and potassium are the building blocks of almost all life.....»»
Eating one wild fish same as month of drinking tainted water: study
Eating one freshwater fish caught in a river or lake in the United States is the equivalent of drinking a month's worth of water contaminated with toxic "forever chemicals", new research said on Tuesday......»»
Scientists investigate anaerobic degradation and conversion of the volatile hydrocarbon isoprene
Isoprene is the world's most abundant biogenic volatile hydrocarbon, and its annual contribution to greenhouse gas emissions is similar to the carbon dioxide equivalent of methane. However, the degradation and transformation of isoprene in the enviro.....»»
Investigating the laser-induced periodic surface structure (LIPSS) of silicon
The electronic and optical devices that we use on a daily basis, such as mobile phones, LEDs and solar cells use transistors and other parts that are consistently getting smaller and more compact. With an ever-growing need for computing power, storag.....»»
About 50% of soil-available phosphorus comes from mineral fertilizers in agricultural systems worldwide
Plants need phosphorus to grow. Farmers' use of mineral phosphorus fertilizers has greatly increased soil phosphorus fertility and, consequently, crop yields. However, these fertilizers are made from rock phosphate, a non-renewable resource that is p.....»»
Active terahertz beam steering based on mechanical deformation of a liquid crystal elastomer metasurface
Traditionally, active metasurface research has primarily focused on changing the dielectric constant and permeability of the substrate, which frequently results in resonance effect and ohmic loss. However, a reconfigurable metasurface based on mechan.....»»
Newly discovered form of carbon is graphene"s "superatomic" cousin
Carbon in its myriad forms has long captivated the scientific community. Besides being the primary component of all organic life on earth, material forms of carbon have earned their fair share of breakthroughs. In 1996, the Nobel Prize in Chemistry w.....»»
Nutrients of the Changjiang river system linked to the land-use changes and climate variability
This study examines the state changes of nutrients (nitrogen, phosphorus and silicon) from one of the ten largest river systems in the world, the Changjiang, based on field expeditions and time-series data since early 1980s. The study covers an area.....»»
Electronic bridge allows rapid energy sharing between semiconductors
As semiconductor devices become ever smaller, researchers are exploring two-dimensional (2D) materials for potential applications in transistors and optoelectronics. Controlling the flow of electricity and heat through these materials is key to their.....»»
Future Apple Pencil could detect colors and textures
Apple could be planning a real-world equivalent of the familiar eye-dropper tool in image apps, where a color could be set by an Apple Pencil tapping against it in an existing image.Back in 2019, Apple applied for a patent concerning an Apple Pencil.....»»
Team develops graphene-based nanoelectronics platform
