Aggregation-induced catalysis: Asymmetric catalysis with chiral aggregates
Asymmetric synthesis and catalysis have been actively pursued in chemical and materials sciences for some time. Increasing numbers of drugs and pesticides contain chiral structural units in their structures since drug actions require conformational m.....»»
How mountains affect El Niño-induced winter precipitation
A consideration of how mountains influence El Niño and La Niña-induced precipitation change in western North America may be the ticket to more informed water conservation planning along the Colorado River, new research suggests......»»
"Silent devastation" of drought set to increase globally under climate change, says UN report
Recent drought-related data compiled by the UN point to "an unprecedented emergency on a planetary scale, where the massive impacts of human-induced droughts are only starting to unfold.".....»»
Laser-induced hydrothermal growth for electrocatalytic applications
In the new study published in the journal International Journal of Extreme Manufacturing on 1 November 2023, researchers from the UK and China reported a novel technique based on a laser-induced hydrothermal reaction (LIHR) mechanism for the growth o.....»»
Green growth or degrowth: What is the right way to tackle climate change?
Nearly all the world's governments and vast numbers of its people are convinced that addressing human-induced climate change is essential if healthy societies are to survive. The two solutions most often proposed go by various names but are widely kn.....»»
Crop yield prediction: New model uses sun-induced chlorophyll fluorescence for enhanced photosynthetic trait estimation
Crops use carbon dioxide (CO2) through photosynthesis to create organic matter, with enhanced photosynthetic rates crucial for meeting global food demands. While crop phenomics has focused on structural traits, it's the functional traits like maximum.....»»
Meet “Amaterasu”: Astronomers detect highest energy cosmic ray since 1991
The Telescope Array in Utah's West Desert picked up a rare particle with 244 EeV energy. Artist’s illustration of extensive air showers induced by ultra-high-energy cosmic rays. Credit: Toshihiro Fujii/L-INSIGHT/Kyoto.....»»
Mind the gap: Study shows estimates of current land-based emissions vary between models due to differing definitions
A new study published in Nature demonstrates that estimates of current land-based emissions vary between scientific models and national greenhouse gas inventories due to differing definitions of what qualifies as "managed" land and human-induced, or.....»»
The formation of switchable and metastable discrete structures through chiral self-sorting
A paper titled "Thermo-/Mechano-Chromic Chiral Coordination Dimer: Formation of Switchable and Metastable Discrete Structure through Chiral Self-Sorting" describes chiral coordination dimers that emerge based on effectively exclusive chiral self-sort.....»»
Research reveals molecular mechanism of asymmetric calcium-sensitive receptor activation
Calcium-sensing receptors (CaSRs), widely distributed in tissues and organs such as parathyroid glands, intestines, bones and kidneys, sense the concentration of calcium ions in the blood and maintain the calcium balance in the human body. CaSR is so.....»»
Researchers tune the speed of chirality switching
Chiral molecules can have dramatically different functional properties while sharing identical chemical formulae and almost identical structures. The molecular structure of two types of a chiral molecule—so-called enantiomers—are mirror images of.....»»
A novel machine learning model for molecular simulation under an external field
Prof. Jiang Bin's research team at the University of Science and Technology of China (USTC) have developed a universal field-induced recursively embedded atom neural network (FIREANN) model, which can accurately simulate system-field interactions wit.....»»
Researchers construct modularized catalytic system for transfer hydrogenation
The precise catalytic conversion of chemical bonds is a paramount goal in catalysis. Enzymes, as efficient biocatalysts, are well known for their high catalytic activity, selectivity, and substrate specificity under mild reaction conditions, which ca.....»»
Researchers extend shelf life of electrolyzers that can convert carbon dioxide to green chemicals
An international research team at DTU has increased the shelf life of electrolyzers that convert CO2 from half a day to 100 hours. This is good news for companies working with the process. The findings were published in Nature Catalysis under the tit.....»»
Geese "keep calm and carry on" after deaths in the flock, says study
Canada geese strengthen existing friendships and forge a few new connections after losing close associates from their flock, new research shows. The paper, published in the Journal of Applied Ecology, is titled "Culling-induced perturbation of social.....»»
Study leverages chiral phonons for transformative quantum effect
Quantum materials hold the key to a future of lightning-speed, energy-efficient information systems. The problem with tapping their transformative potential is that in solids, the vast number of atoms often drowns out the exotic quantum properties el.....»»
Mac sales are resuming normal growth, after pandemic and Apple Silicon bumps
Understanding what’s happening to Mac sales over the past few years is a tricky business, due to the convergence of three different factors: pandemic-induced demand, COVID-related supply disruptions, and early upgrades driven by the switch to Apple.....»»
Global warming–induced sea level changes could increase earthquake risk
Earthquakes often occur along plate boundaries, when sudden movements of the "stuck" plates release elastic strain energy, sending out seismic waves that result in the ground shaking familiar to many worldwide. More rarely, earthquakes occur within p.....»»
Research explores molecular basis of ventilator-induced diaphragm weakness
A study, published in PNAS Nexus, presents evidence that mitochondrial fragmentation is a proximal mechanism underlying ventilator-induced diaphragm dysfunction (VIDD)—and identifies a possible therapeutic to limit diaphragm atrophy during a stay.....»»
Gate induced room-temperature magnetic phase transition realized in van der Waals ferromagnet nanoflakes
