Plasmonic Nanomachines: Creating Local Potential Gradients and Motions

Advanced Materials, EarlyView.
Plasmonic nanomachines can generate optical, thermal, and chemical potential gradients to drive directional rectilinear, rotational, and twisting motions at the nanometer scale. The integration of multimodal plasmonic forces with functional materials and programmed structural distortions enables precise spatiotemporal actuation, thereby providing a ...

A Comprehensive Review of Waste‐Derived Materials for Solar Still Performance Enhancement

Advanced Materials Interfaces, EarlyView.
Solar desalination reduces energy use and produces freshwater sustainably, but its productivity is limited and cannot meet rising demand. Thus, solar desalination system improvements are sought to boost water productivity. Waste materials are abundantly available and burden the environment, making them low‐cost enhancers for solar desalination systems.

Expansion of Thermoelectric Effect

, 2023
Abstract The thermoelectric effect of two metals was discovered by T. J. Seebeck, a German physicist. This research extends the thermoelectric effect of Seebeck's two metals. In this research, the thermoelectric effect of 16 materials, including soil, was tested.

Mechanical Stress Evolution in Polycrystalline Ge Thin Films Under MeV Ion Irradiation

Advanced Materials Interfaces, EarlyView.
Irradiation of polycrystalline Ge thin films with 1.8 MeV Au ions alters residual stress through defect generation and lattice expansion. Increasing fluence drives progressive lattice disorder and eventual amorphization. Polycrystalline Ge resists amorphization longer than crystalline Ge, as grain boundaries facilitate defect diffusion, significantly ...
