Proteins in focus: Dynamically tunable protein microdevices were built up by a simple “top-down”, maskless, femtosecond laser direct writing approach with bovine serum albumin. This technique was used to produce biocompatible microlenses that swell and shrink reversibly response changes the pH of surrounding solution. These responses environmental stimuli can be focus microlenses.
For effective hydrogen generation with remarkable durability, carbon nanotubes (CNTs) grown on Ni nanofibers and their post hydroxylation treatment engendered active nanofiber catalysts an efficient decomposition of hydrous hydrazine a turnover frequency (TOF) 19.4 h-1 activation energy down to 51.05 KJ mol-1.
We report on the fabrication of a NO2 gas sensor from room-temperature reduction graphene oxide(GO) via two-beam-laser interference (TBLI).

Rapid human motion pose tracking has extensive applications in fields such as capture, intelligent monitoring, sports training, and physical health management. It can provide accurate data support, enhance safety optimize training outcomes, promote health. Traditional methods predominantly rely on either sensors or images for tracking, which often results issues like low accuracy slow speed. To address these problems, a rapid method based improved deep reinforcement learning multimodal...
Compact 5-mm-long 100-μm-period long-period fiber gratings (LPFGs) are fabricated by femtosecond laser direct writing. Nearly symmetrical photomodified grating segments located at the center of a core lead to well-defined transmission spectra.
