In a paper published in the Journal of the American Chemical Society researchers experimentally synthesized for the first time Mg₂RhH₆ that exhibits superconductivity at a significantly reduced pressure of 30 GPa. Mg₂RhH₆ was synthesized via a two-step process and showed superconductivity with a maximum T_c of 29 K. The findings open a highly promising pathway for the rational design and discovery of high temperature superconductors at accessible pressures for industrial pressure facilities.

Scintillators convert high energy radiation into detectable light, making them essential materials for radiation detection and X ray imaging. Yet some of the energy deposited by radiation is lost before it can be emitted as light. A study published in Research shows how restructuring the light emitting units in a metal halide can reduce these losses by confining electronic excitations more strongly.

Meteorites carry some of the most complex organic chemistry known outside biology — tens of thousands of compounds that may predate life itself — yet most studies track only a few star molecules such as amino acids. Researchers at the Chinese Academy of Sciences now propose "prebiomics," applying omics-style, high-throughput analysis to the full soluble organic inventory of meteorites. Combining 10-micrometer-resolution mass spectrometry imaging with ultra-high-performance liquid chromatography across nine meteorites spanning weak to strong water alteration, they mapped roughly 3,000 soluble organic components. The organics cluster in water-altered phyllosilicates and chondrule rims but avoid carbonates; their abundance tracks alteration degree in CM2 chondrites while highly altered CI1 samples break the trend — evidence that source region, parent-body fluids and mineral microenvironments jointly govern extraterrestrial organic evolution.

Researchers at Sun Yat-sen University have tailored the nitrogen environment around individual platinum atoms to improve the selective hydrogenation of sulfur-containing nitroarenes. The optimized catalyst combines high activity with sulfur tolerance, retaining more than 99% selectivity over five reuse cycles. Experiments and calculations link this performance to efficient hydrogen activation and weaker sulfur binding.

Titanium alloys like Ti-6Al-4V (TC4) feature lightweight, high strength and outstanding corrosion resistance, are widely used in aerospace, shipbuilding and nuclear industries. Combining TC4 with SS316L stainless steel can reduce structural weight and lower costs, yet their significant differences in thermal properties and metallurgical compatibility easily generate brittle Ti-Fe intermetallic compounds, causing severe joint embrittlement and strength loss. Existing Ti-based amorphous brazing fillers still struggle to balance intermetallic suppression and bonding strength, limiting industrial application.

The fabric sunshade that keeps a parked car's cabin up to 17.8 °C cooler draws no power at all. Researchers wove a hierarchical metafabric that reflects 94.3% of sunlight and emits 95.8% of the mid-infrared radiation that carries heat away, while fluorescent particles convert ultraviolet light into visible light with a 16.4% quantum yield instead of letting it become heat. The fabric reached a net cooling power of 130.13 watts per square meter — versus 77.23 without the fluorescent layer — and ran 14.4 °C cooler than a commercial sunshade in vehicle tests. It kept 93.6% of its reflectivity after 100 abrasion cycles and comes off the coater 1.2 meters wide, targeting glass towers and electric-vehicle sunroofs.
