3+ hour, 33+ min ago   (333+ words) In space-vector-modulation-based flux-linkage-loop-free direct torque control (SVM-FLLF-DTC) for permanent magnet synchronous motor (PMSM) drives, the open-loop d-axis voltage control causes an inherent magnetization effect, and the conventional single-axis flux-linkage limiting strategy entails a risk of positive-feedback runaway. To address these…...

6+ hour, 21+ min ago   (234+ words) South Korea’s INFAC Corporation has introduced an innovative 800V battery pack design block for electric vehicles that integrates a high-power 800V-to-48V isolated and regulated DC-DC converter. The new design improves vehicle performance, power efficiency and boosts range through the reduction of…...

2+ hour, 19+ min ago   (27+ words) Both tables read 22 °C, yet only the metal feels cold. What decides it is thermal effusivity, not conductivity — and I calculate how cold your skin gets....

6+ hour, 50+ min ago   (174+ words) A team of Department of Chemistry researchers won the “Best Scientific Poster Presentation” award at the 75th Annual Convention of the Philippine Association for the Advancement of Science and Technology and Innovation (PhilAASTI) on September 10, 2026, at the Manila Hotel. The award-winning…...

7+ hour, 16+ min ago   (265+ words) The trifluoromethyl group, or CF₃, is widely used in pharmaceuticals. When added to organic molecules, it can improve metabolic stability and membrane permeability, making it highly valuable in drug development. One useful way to introduce CF₃ group is through the use of…...

7+ hour, 54+ min ago   (505+ words) LG has made a battery breakthrough that could bring down the costs of electric cars further, as the race to develop more efficient technology heats up. Electrical technology company LG Energy Solution and Seoul National University have announced a breakthrough…...

9+ hour, 11+ min ago   (301+ words) The challenge lies in the fact that both the electrodes and electrolytes in sulfide all-solid-state batteries are solids. During charge–discharge cycling, the volume of the solid electrodes changes slightly, creating microscopic gaps at the interface where they contact the…...

8+ hour, 56+ min ago   (737+ words) Researchers at Hebei University of Technology, Nankai University, and the Oil & Gas Technology Research Institute of Huabei Oilfield Company have developed a millimeter-scale, magnetically recoverable carbon bead catalyst that achieves complete removal of the antibiotic sulfamethoxazole (SMX) from water within…...

9+ hour, 37+ min ago   (493+ words) A homeowner with $50,000 to spend on an off-grid power system turned to Reddit's r/SolarDIY community to ask whether they could design a setup around a 100+ kilowatt-hour battery bank without blowing through their budget. The replies offered a reality check,…...

9+ hour, 14+ min ago   (488+ words) In a recent research article published as an 'Article in Press' in the journal Scientific Reports, researchers investigated the control of the diffusive motion of fullerene-wheeled nanovehicles, including C60, nanocars, and nanotrucks, using all-atom molecular dynamics simulations on hybrid curved substrates…...
