Hiroshima scientists crack the code for 3D printing tungsten carbide

The university's team reports that their approach centers on controlled "softening" of the material rather than complete melting. The process, known as hot-wire laser irradiation, reshapes tungsten carbide while maintaining its exceptional hardness and minimizing defects – an achievement that could transform how cutting, drilling, and construction tools are manufactured....

EV batteries age twice as fast with ultra-fast charging

The firm analyzed data from more than 22,700 vehicles across 21 models and found a striking pattern: batteries subjected to frequent charging sessions above 100 kilowatts degraded at roughly twice the rate of those primarily using lower-power options such as Level 2 chargers. Read Entire Article
