This work experimentally studies a silicon-cored tungsten nanowire selective metamaterial absorber to enhance solar-thermal energy harvesting. After conformally coating a thin tungsten layer about 40 nm thick, the metamaterial absorber exhibits almost the same total solar absorptance of 0.85 as the bare silicon nanowire stamp but with greatly reduc...

A photoelectrochemical biosensing strategy for the highly sensitive detection of the flavonoid rutin was developed by synergizing the photoelectrocatalytic properties of hematite (α-Fe2O3) decorated with palladium nanoparticles (PdNPs) and the biocatalysis towards laccase-based reactions. The integration of α-Fe2O3.PdNPs with a polyphenol oxidase a...

In this work, Ag dendrites were obtained using a one-step green method by Hamelia patens aqueous extract. Cyclic voltammetry measurements evaluated the electrochemical characterization of Ag nanostructures. Scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), ultraviolet–visible spectroscopy (UV–vis), X-ray diffraction (XRD), a...

Recent studies have shown that nanosized materials including plastics as a major cause of concern in the aquatic ecosystem. Fortunately, in the aquatic environment, the surface of the materials is often colonized by exudates of aquatic microorganisms (biofilm), where these materials are attached and surrounded by a secreted matrix with a sticky lay...

Herein, a new 2-dimensional coordination polymer based on copper (II), {Cu2(L)(DMF)2}n, where L stands for 1,2,4,5-benzenetetracarboxylate (complex 1) is synthesized. Interestingly, we demonstrate that both solvent and sonication are relevant in the top-down fabrication of nanostructures. Water molecules are intercalated in suspended crystals of co...

Platinum group metals, such as Pd and Pt, found in three-way catalyst converters were recycled in a two-step method: hydrodynamic cavitation followed by sonoelectrochemical dissolution. High shear forces were obtained by using a convergent nozzle with a throat diameter of 0.2 mm, feeded by a plunger pump at a pressure of 60 MPa. Cavitating submerge...

BackgroundBanana bunchy top virus (BBTV) is a destructive viral disease in many countries including Egypt; it causes severe economic losses in banana crop. Recently, nanotechnology was used to generate resistance against plant viruses. The main purpose of this study was to use silver nanoparticles (AgNPs) as antiviral agents against BBTV. In this r...
