Nanoscale Lamb wave-driven motors in nonliquid environments
Light driven movement is challenging in nonliquid environments as micro-sized objects can experience strong dry adhesion to contact surfaces and resist movement. In a recent study, Jinsheng Lu and co-workers at the College ...
Engineering 3-D mesostructures with mechanically active materials
Microelectromechanical systems (MEMS) have expansive applications in biotechnology and advanced engineering with growing interest in materials science and engineering due to their potential in emerging systems. Existing techniques ...
Nanoparticles with a shell structure improve the performance of zinc-oxide photodetectors
Improving the sensitivity of light sensors or the efficiency of solar cells requires fine-tuning of light capturing. KAUST researchers have used complex geometry to develop tiny shell-shaped coverings that can increase the ...
