Clingy copper ions contribute to catalyst slowdown
Heavy-duty diesel trucks on the road today are equipped with aftertreatment systems that include selective catalytic reduction (SCR) technology using urea solution as a reducing agent to curtail harmful nitrogen oxide (NOx) emissions from engine exha.....»»
Theoretical perspective on C-H/O-H activation by Cu-O in biological and synthetic systems
Dioxygen activations constitute one of the core issues in copper-dependent metalloenzymes. Upon O2 activation, copper-dependent metalloenzymes, including particulate methane monooxygenases (pMMOs), lytic polysaccharide monooxygenases (LPMOs) and binu.....»»

The Russia - Ukraine conflict proved to be quite the catalyst for DDoS attacks.....»»
Study reveals petrogenesis of porphyry copper deposits in southern Tibet
The Gangdese porphyry copper deposit belt (GPCDB) is along the southern margin of Lhasa Terrane. The deposits of GPCDB were formed in the Miocene after the India-Eurasia collision. The genesis of these porphyry copper deposits is controversial......»»
Tuning exact ratios of two metals in a catalyst may enable new directions in catalysis science
In the last 20 years, there have been efforts to reduce fossil fuel use in plastics manufacturing, and, according to Penn State researchers, efficient, customizable catalytic reactions—where two metals are combined using a catalyst, or molecule tha.....»»
Haber-Bosch at the atomic scale
Industrial production of NH3 has been performed by the Haber-Bosch process for more than 100 years, in which dissociation of N2 feedstock molecules promoted by alkali atom co-catalyst is thought to be the rate limiting step. The Haber-Bosch synthesis.....»»
"Spring-loaded" system pops phosphorus into molecular rings
MIT chemists have devised a new chemical reaction that allows them to synthesize a phosphorus-containing ring, using a catalyst to add phosphorus to simple organic compounds called alkenes......»»
Ag3PO4 catalyst facilitates propylene oxide electrooxidation
There is a great need for the green production of propylene oxide (PO) due to its high industrial value. The electrooxidation of propylene into PO has aroused the interest of scientists because the process can be conducted under room temperature cond.....»»
TSMC to see HPC chip orders contribute over NT$700 billion to 2022 revenue
TSMC is expected to see revenue generated from the HPC sector contribute more than NT$700 billion (US$23.9 billion) to the pure-play foundry's total revenue this year, according to market sources......»»
Some gut viruses promote intestinal health, while others contribute to inflammatory bowel disease
The findings suggest that patients with inflammatory bowel might benefit from therapies that replace disease-driving intestinal viruses with health-promoting viruses......»»
III-V IC makers see slowdown as mobile phones lag in 2Q22
Smartphone demand in the second quarter of 2022 continues to be bleak. Inventory pressure and shrinking consumer spending in China's domestic market mean China-based mobile phone brands are bearing the brunt......»»
Simulations explain Greenland"s slower summer warming
A puzzling, decade-long slowdown in summer warming across Greenland has been explained by researchers at Hokkaido University in Japan. Their observational analysis and computer simulations revealed that changes in sea surface temperature in the tropi.....»»
How Pacific decadal oscillation modulates the El Niño-related eastward transport anomaly
The equatorial intermediate currents (EICs) contribute to global circulation, climate variability, and distributions of heat, water mass, and biogeochemical quantities......»»
How can local policies contribute to global sustainability goals?
The challenges of building a sustainable society are unprecedented. But the Dutch municipalities cannot be faulted for their commitment. They are working hard, conclude Professor Eefje Cuppen and Lian Merkx, program manager for energy at the Associat.....»»
New, faster method to measure global warming shows no acceleration or slowdown
In a recent study published in Nature Communications, international scientists have taken on a persistent problem in climate science: near-term climate evolution......»»
Both downtown and suburbs appeal to small, high-growth firms
The movement of high-growth firms that directly contribute to the regional economy may be more complex than previously thought, new research suggests......»»
How "inert" compounds can steal ions
Cells produce many different complexes. These complexes can occupy 40% of the cell's volume, making the cell quite a crowded environment. For that reason, a full description of complex cellular behavior is a challenge that requires deeper investigati.....»»
Digitalization and sustainability: How do DAX companies measure up?
Can digitalization contribute to the development of a more sustainable economy? Sustainability has emerged as a key concern for many DAX companies—but only insofar as their customers call for improvement. Most are reluctant to make more sweeping ch.....»»
Cheap, eco-friendly catalyst opens new possibilities for organic molecules built from pyruvate
Chemists at the Okinawa Institute of Science and Technology Graduate University (OIST) have developed an organic catalyst that can drive reactions using pyruvate—a key biomolecule in many metabolic pathways—that are difficult and complicated to a.....»»
Japan MLCC makers maintaining prices despite slowdown in CE demand
A slowdown in demand for consumer electronics devices has prompted Taiwan-based MLCC suppliers to cut commodity MLCC prices, but their larger Japan-based peers continue to keep prices unchanged, according to industry sources......»»
Silicon wafer suppliers continue to see orders from foundries despite end-market slowdown concerns
Silicon wafer companies and other upstream chipmaking material providers continue to see their production capacities fully utilized by the still strong pull-in of orders from foundries, which are commencing their aggressive capacity expansion project.....»»
