Induced-fit adsorbent for acetylene
We often say that a substrate fits into its enzyme like a key in a lock, but this metaphor is imperfect. Substrate binding can also change the lock (the structure of the enzyme) to induce a perfect fit. In the journal Angewandte Chemie, an internatio.....»»
Microprocessor sales growth to slow in 2022, says IC Insights
Worldwide microprocessor sales grew 14% to a record-high US$102.9 billion in 2021, after climbing 16% in 2020, when COVID-induced lockdowns drove up demand for PCs, large-screen smartphones and other devices enabling stay-at-home initiatives, accordi.....»»
New model helps predict climate change-induced early spawning in fish
Fisheries managers and researchers may now predict how early fish will spawn in response to warming waters due to climate change, both in the oceans and in freshwaters......»»
Multiframe imaging of micron and nanoscale bubble dynamics
The formation and collapse of microscopic bubbles is important in a wide range of fields as both a potential mechanism behind tissue damage, such as in cases of blast-wave-induced traumatic brain injury, and as a useful tool for technology applicatio.....»»
Human-induced climate change impacts the highest reaches of the planet—Mount Everest
Melting and sublimation on Mount Everest's highest glacier due to human-induced climate change have reached the point that several decades of accumulation are being lost annually now that ice has been exposed, according to a University of Maine-led i.....»»
One in five fish dies from passing hydroelectric turbines
Hydroelectric turbines put fish at risk of severe injury during passage. To support an informed debate on the sustainability of hydropower, reliable data of turbine-induced fish mortality are pivotal. A team of researchers of the Leibniz Institute of.....»»
A nonlinear-transport perspective of field-induced phase transitions in pentatellurides
Combining topological states of matter with strong electron correlation promises many exotic phenomena such as charge fractionalization, excitonic instability, and axionic excitation. Layered transition-metal pentatellurides ZrTe5 and HfTe5 were foun.....»»
Supply-side constraints to push up memory contract prices
DRAM and NAND flash contract prices are likely to rally sooner than previously expected, due to supply-side constraints arising from COVID-19 induced lockdowns in China, according to industry sources......»»
Lost birds and mammals spell doom for some plants
In one of the first studies of its kind, researchers have gauged how biodiversity loss of birds and mammals will impact plants' chances of adapting to human-induced climate warming......»»
Data confirm link between respiratory stress and fish reproduction
A consistent metabolic ratio found across 133 Chinese marine and freshwater fish species provides new evidence in support of the idea that fish become sexually active—and spawn for the first time—in response to growth-induced respiratory stress......»»
Controlling self-doping in magnetite with temperature
One of the most abundant iron-containing minerals on Earth, and also the oldest known magnetic material, is magnetite, Fe3O4. Magnetite has applications in many fields, such as the study of paleomagnetism—magnetism in rocks induced at the time of t.....»»
Highlights of the day: DDR4 spot prices rising
Demand may be still sluggish, but DDR4 spot market prices are already rising, thanks to supply side issues in the wake of COVID-induced lockdowns in the Chinese city of Xi'an, where Samsung and Micron both run memory fabs. Networking IC vendor Realte.....»»
Micron warns of Xi"an lockdown impact on chip manufacturing
The latest COVID-induced lockdown in the Chinese city of Xi'an could disrupt operations at Micron Technology's manufacturing site locally in Xi'an, according to the US memory chip vendor......»»
Highlights of the day: Samsung NAND production in Xi"an faces lockdown challenge
The latest COVID-induced lockdown in the Chinese city of Xi'an has threatened to disrupt manufacturing at some tech giants' facilities there, including Samsung's NAND flash production. Samsung has maintained its production in Xi'an remains normal, bu.....»»
Preparing, and paying for, climate change-induced disasters
During the evening hours of Dec. 10, a flurry of tornadoes ravaged several states, claiming close to 100 lives and leaving whole communities in wreckage. According to the United States National Oceanic and Atmospheric Administration, the storms were.....»»
Blackwood: A magnificent timber and a tough, towering wattle that can survive landslides
After the long COVID-induced lockdowns of 2021, I'm more excited than usual for a joyous gathering at Christmas, where four generations of our family will sit around our much-used dining table for dinner......»»
Exploring factors impacting the sensitivity of amorphous oxide semiconductors to externally induced impurities
In recent years, electronics engineers have been trying to broaden the pool of available semiconducting materials, to enable the development of a wider range of devices. One emerging class of semiconductors are amorphous oxide semiconductors (AOSs),.....»»
Illuminating mechanism of carbonate mass-transport deposits
Subaqueous mass-transport processes, including gravity-induced slides, slumps and debris flows, are one of the mechanisms for transport of sediment into the deep sea......»»
Researchers propose new method for electrocatalytic hydrogenation of acetylene to ethylene under room temperature
Ethylene is one of the most important building blocks in chemical synthesis. Traditional thermocatalytic hydrogenation of acetylene to ethylene (HAE) requires high temperatures and high pressure, leading to excessive energy consumption. Additionally,.....»»
Tropical frogs can adapt to climate change, but rapidly warming temperatures still pose a huge threat
An international group of researchers have found evidence of tropical frogs adapting to warming temperatures, but warn that human-induced climate change still poses a huge threat to species' survival......»»
Predicting Great Lakes meteotsunamis with better modeling
Weather-induced tsunami events can cause water levels to rise two meters in 10 minutes. A new, improved forecasting model will help Great Lakes communities prepare and respond......»»
