Abstract Catechol offers switchable adhesion in response to electrochemical redox reaction. However, electrochemistry requires water for effective proton transport, but water weakens adhesive performance. Here, we incorp...

The electrophysical properties of magnesium oxide chemically modified with copper iodide have been studied in the superfrequency range and low-frequency in the temperature range 25 – 170<sup>о</sup>С and ...

The present study involves an assessment of pollution through the impact of heavy metals in the waters of the 17 July estuaries, the Industrial zone on the left, Muthanna coasts, and the Nineveh Bridge of the Tigris Rive...

The aim of this study is to evaluate the irrigation water quality of Kuzgun Dam, which supplies water to the agricultural lands of Daphan Plain, located in Erzurum Province, Türkiye. Water samples were collected from se...

The design of sulfur hosts with polar, sulfurphilic, and conductive network is critical to lithium-sulfur (Li-S) batteries whose potential applications are greatly limited by the lithium polysulfide shuttle effect. Mxene...

Metallic helical metamaterials have become the prominent candidates for circular polarizers and other optical-chiral devices as they exhibit strong circular dichroism at a broad operation bandwidth. However, the rapid fa...

Abstract This study aimed to map geological structures and characterize groundwater aquifers in the Meki–Alemtena area of the East Shewa Zone, Ethiopia. Sixteen Vertical Electrical sounding data were collected to revea...

The purpose of this study was to assess hydrological controls (e.g., rainfall, irrigation practices, river discharge, dam operation, evaporation) on surface (SW)- ground water (GW) interactions in an irrigated valley wit...

The main objective of the study is to improve energy efficiency of a shell-and-tube jet injection fer-menter (SJT) for aerobic cultivation of microorganisms. The relevance of the work is determined by the biotechnology i...

In this work, we report a class of high surface area biomass derived carbon material- (BCMs) obtained from industrial black tea process waste biomass (TW) as a support for synthesis of the nanoparticulate Pt supported on...

Supercapacitors, with the merits of both capacitors for safe and fast charge and batteries for high energy storage have drawn tremendous attention. Recently, laser scribed graphene has been increasingly studied for super...

The Paraná River floodplain comprises one of the largest wetland systems of South America. In a sector of the Lower Paraná River floodplain (100km length, 3650km2), floristic composition and species diversity was chara...

Abstract Wetlands are invaluable places with a distinct ecosystem that shares the features of both aquatic and terrestrial ecosystems. Macroinvertebrates are vital components of wetland ecosystems. Therefore, this study ...

In this research the application of nanomaterials, nanocomposites reformed in semiconductor and chip sectors by fabricating them resulted in better performance compared to previous studies. These developed materials has ...

Analysis of impedance spectrum of electroporated biological cell suspensions allows evaluating the state of permeabilization produced by the applied electric field. In this article we used a genetic algorithm to determin...
