During femtosecond laser fabrication, photons are mainly absorbed by electrons, and the subsequent energy transfer from electrons to ions is of picosecond order. Hence, lattice motion is negligible ...
Demand for artificial intelligence is boosting GPU stocks. Nvidia is the leader in the field, with significant sales growth and market dominance. Diversification plays include ETFs like VanEck ...
Liquid crystal elastomers have potential as 4D-printing actuators, but it is difficult to achieve complex shape changes in structures. Here, the authors report a 4D-printing strategy that combines vat ...
