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.....»»
Unveiling oxidation-induced super-elasticity in metallic glass nanotubes
Oxidation can degrade the properties and functionality of metals. However, a research team co-led by scientists from City University of Hong Kong (CityU) recently discovered that severely oxidized metallic glass nanotubes can attain an ultrahigh reco.....»»
Whether a racial minority or majority at their school, white teachers struggle with race relations
White workers' emotions about race and reactions to racial differences in the workplace are triggered by identity threat-induced culture shock, researchers suggest in a new study......»»
Physicists develop novel concept for detecting chiral molecules
In contrast to conventional mirrors, light can be reflected on surfaces known as metasurfaces without changing its polarization. This phenomenon has now been proven by physicists at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) and the Ma.....»»
A breath of fresh air in plasmonic catalysis: Black gold and solar light"s renaissance
Prof. Polshettiwar's group at Tata Institute of Fundamental Research (TIFR), Mumbai has developed a novel "plasmonic reduction catalyst stable in air," defying the common instability of reduction catalysts in the presence of air. The catalyst merges.....»»
Researchers slow down light in metasurfaces with record low loss
The speed of light can be intentionally reduced in various media. Various techniques have been developed over the years to slow down light, including electromagnetically induced transparency (EIT), Bose-Einstein condensate (BEC), photonic crystals, a.....»»
Study shows cells respond quickly to small light-induced micro-environment movements
Life sciences and photonics researchers at Tampere University have made a remarkable discovery in studying superficial cells' response to mechanical stimuli. By simulating the deformation of the extracellular matrix below the cells, researchers have.....»»
Global warming was primary cause of unprecedented Amazon drought, study finds
Human-induced global warming, and not El Niño, was the primary driver of last year's severe drought in the Amazon that sent rivers to record lows, required deliveries of food and drinking water to hundreds of river communities and killed dozens of e.....»»
Hubble observes an askew galaxy coaxing star formation from its partner
Arp 300 consists of two interacting galaxies, UGC 05028 (the smaller face-on spiral galaxy) and UGC 05029 (the larger face-on spiral). Likely due to its gravitational dance with its larger partner, UGC 05028 has an asymmetric, irregular structure, wh.....»»
Understanding man-made earthquakes: Study highlights role of fault roughness and stress heterogeneity
Man-made earthquakes, or induced seismicity, have become an increasing concern. These events can occur during fluid injection or extraction, such as in oil or gas reservoirs, wastewater disposal, or geothermal reservoirs......»»
Research reveals gas-phase migration route for formation of strong metal-support interaction state
Strong metal-support interaction (SMSI) is one of the most important concepts in heterogeneous catalysis. Triggered by pretreatment or reaction processes, the supported metal nanoparticles may be partially or completely encapsulated by support-derive.....»»
The pros and cons of oxygen mediating the performance of nickel catalysts in dry reforming of methane
Catalysis is one of the key technologies in the chemical industry and has a wide-reaching impact on various aspects of our daily lives, including plastics manufacturing, drug synthesis, and production of both fertilizers and fuels. It is estimated th.....»»
Review covers optical aspects of quantitative photoacoustic tomography
Quantitative photoacoustic tomography (QPAT) is a medical imaging technique that combines laser-induced photoacoustic signals and ultrasound detection to create detailed three-dimensional images of biological tissues. The process involves irradiating.....»»
Methane activation by [LnO]+: The 4f orbital matters
As the "holy grail" in the field of chemistry, the catalytic activation of methane has been a topic of great interest in the field of heterogeneous catalysis. Gas-phase experiments provide an ideal platform for exploring catalytic reaction mechanisms.....»»
Transferring laser-induced graphene at extremely low temperatures for ultrathin bioelectronics

A three-step mechanism explaining ultraviolet-induced CO desorption from CO ice
The desorption of CO ice induced by ultraviolet (UV) radiation is a phenomenon that occurs in some cold parts of the universe, which has often also been replicated in laboratory settings. While this phenomenon is now well-documented, the molecular me.....»»
Researchers report successful synthesis of specific chiral molecules using rearrangements of simple hydrocarbons
In nature, organic molecules are either left- or right-handed, but synthesizing molecules with a specific "handedness" in a lab is hard to do. Make a drug or enzyme with the wrong "handedness," and it just won't work. Now chemists at the University o.....»»
Orbitally induced strong monsoons facilitated early human dispersal to East Asia, finds study
In a study published in Proceedings of the National Academy of Sciences, researchers have shown that orbitally induced strengthening of the Asian summer monsoon played a key role in the dispersal of Homo sapiens from Africa to East Asia during the la.....»»
Hurricane waves hitting Americas grow 20% per decade: Study
The U.S., Mexico and countries in the Caribbean are being battered by hurricane-induced ocean waves that have grown in areal size by 80% over the past 40 years, a new study has found......»»
Stripes in a flowing liquid crystal suggest a route to "chiral" fluids
Hold your hands out in front of you, and no matter how you rotate them, it's impossible to superimpose one over the other. Our hands are a perfect example of chirality—a geometric configuration by which an object cannot be superimposed onto its mir.....»»
