Scientists have identified a way for a solar-energy material to absorb light strongly while holding on to the resulting electrical charges for longer. The finding could help overcome a trade-off that limits how effectively some materials convert sunlight into useful…
Solar-powered aircraft could stay aloft for weeks or months, but making that possible depends heavily on the batteries carrying them through each night. A new study identifies a battery target that could make persistent flight practical across much wider areas.
Tiny cracks can help soft electronic materials conduct electricity, researchers have discovered. When the material is squeezed, liquid metal flows through the openings and connects previously separated droplets into electrical pathways. The finding explains a process researchers had used for…
Root and tuber vegetables, including potatoes, radishes, sweet potatoes, and carrots, are important components of Korean upland agriculture, yet harvesting and yield determination remain less mechanized and digitally integrated than cereal production. This review integrated contact- and weight-based yield measurement…
The development of efficient and recoverable catalysts is essential for advancing carbon dioxide utilization technologies and improving the sustainability of catalytic processes. Magnetic iron oxide-based composites supported on carbon materials are particularly promising due to the combination of catalytic activity,…
Methylxanthines are naturally occurring purine alkaloids widely present in cocoa-based products. Due to the relatively high fat content of these matrices and their complexity, appropriate sample preparation is an important step for their determination. This research examines the applicability of…
Titanium engineering boosts thin-film thermoelectric performance by 250 times, offering new possibilities for efficient energy harvesting, waste-heat recovery and compact power generation in electronic devices. Titanium Advances Thin-Film Thermoelectric Electronics Titanium engineering boosts thin-film thermoelectric performance by 250 times, offering new possibilities…
A cobalt-free compositional strategy was pursued to promote Ce incorporation in M-type SrFe12O19 and thereby enhance its hard magnetic performance. In Sr1−xCexFe12−xMgxO19 (x = 0–0.15), the highest coercivity and finest microstructure were obtained at x = 0.1; however, a residual CeO2 phase persisted at all substitution levels, suggesting…
A machine learning model built on eight material descriptors predicted the specific capacity of nitrogen-doped porous carbon cathodes for zinc-ion hybrid supercapacitors, and an optimized device synthesized to test it delivered 160.3 mAh g–1 at 0.1 A g–1, close to the predicted 154.4 mAh g…
Silica nanoparticles boosted the emission intensity of a bluish-green Ba2SiO4:Eu2+ phosphor by 48 percent over a conventional-silica version, and a flexible remote phosphor film made from the optimized material retained 56 percent of its luminescence at 190 degrees Celsius. Silica nanoparticles boost bluish-green phosphor…
