This study reports the tensile strengths of J55 and P110 tubular steels at low temperatures and assesses the consistency of the geometry, loading, and material inputs in an existing single-tube Abaqus/Explicit model. Ten tensile tests were conducted at five chamber temperatures…
The experiment began with an intense, ultrashort laser pulse that excited electrons in the material and triggered coordinated changes in their spins. Magnons emerged within femtoseconds (one quadrillionth of a second). Over the following picoseconds (one-trillionth of a second), the…
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…
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…
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…
Chemists have created graphene-enzyme hybrids in which immobilized lipases induce the formation of palladium and copper nanoparticles that catalyze carbon-carbon bond-forming reactions with high selectivity in water and organic solvents.
