High piezo-photocatalytic efficiency of degrading organic pollutants has been realized from CuS/ZnO nanowires using both solar and mechanical energy. heterostructured nanowire arrays are compactly/vertically aligned on stainless steel mesh by a simple two-step wet-chemical method. The mesh-supported nanocomposites can facilitate an efficient light harvesting due to the large surface area also be easily removed treated solution. Under ultrasonic irradiation, rapidly degrade methylene blue...
Exploring nanoscale material properties through light-matter interactions is essential to unveil new phenomena and manipulate materials at the atomic level, paving way for ground-breaking advancements in nanotechnology science. Various elementary excitations low-energy modes of reside terahertz (THz) range electromagnetic spectrum (0.1–10 THz) occur over various spatial temporal scales. However, due diffraction limit, a slew THz studies are restricted drawing conclusions from spatially...
