The Large Hadron Collider at CERN, delivering proton–proton collisions at much higher energies and far higher luminosities than previous machines, has enabled a comprehensive programme of measurements of the standard model (SM) processes by the CMS experiment. These unprecedented capabilities facilitate precise measurements of the properties of a wide array of processes, the most fundamental being cross sections. [...]

The production of nickel-base superalloys through powder bed fusion using alaser beam (PBF-LB) offers a promising method for reducing the cost of aeronauticalcomponents, especially those with complex geometries. However, whenthese materials are processed using PBF-LB, the standard heat treatmentsdeveloped for conventional manufacturing routes do not consistently yieldpredictable microstructures or mechanical properties. [...]

Seeds harbor diverse endophytic microbes that can be transmitted to offspring through parental plants. However, studies on the seed microbiomes of metal hyperaccumulators—plants capable of accumulating high levels of specific metals in their tissues—are scarce. [...]

Rice (Oryza sativa L.) farmers face challenges with metal accumulation in grain, with nickel (Ni) recently emerging as a concern due to its potential to exceed legal limits, alongside cadmium (Cd). Information on Ni behaviour and its interaction with Cd remains limited. [...]

The edge states (ES) in two-dimensional (2D) hybrid lead halide perovskites (LHPs) exhibit distinct electronic characteristics, including lower energy and longer lifetimes compared to the interior states (IS). Though the ES of these 2D LHPs show prospect of facilitating photovoltaic and optoelectronic effects, the underlying mechanism remains elusive. [...]

For CO2 hydrogenation over iron-based catalysts, revealing the promoting effect of manganese and the nature of catalytically active sites remains a challenge that hinders targeted catalyst design. Here we elucidate the manganese-modulated restructuring of such catalysts during preconditioning and CO2 hydrogenation using in situ X-ray absorption spectroscopy. [...]

Photodetectors are fundamental components of modern optoelectronics, enabling the conversion of light into electrical signals. The development of high-performance phototransistors necessitates materials with both high charge carrier mobility and robust photoresponse. [...]
