Water harvesting from the ubiquitous moisture is pivotal for delivering fresh water to earth's arid/semiarid regions, and sequestration of iodine solution crucial environmental safety due its severe effect on human metabolic processes. In this context, herein, a multifunctional supramolecular metallohydrogel (Mg@TAEA) synthesized through direct mixing magnesium nitrate hexahydrate low molecular weight gelator tris(2-aminoethyl)amine. Electron microscopy reveals that Mg@TAEA sculptured in...

Abstract Phosphorene is a unique semiconducting two-dimensional platform for enabling spintronic devices integrated with phosphorene nanoelectronics. Here, we have designed an all lattice lateral spin valve device, conceived via patterned magnetic substituted atoms of 3d-block elements at both ends nanoribbon acting as ferromagnetic electrodes in the valve. Through First-principles based calculations, extensively studied spin-dependent transport characteristics new structures. Systematic...
Phosphorene is a promising single elemental two-dimensional layered semiconductor with huge potential for future nanoelectronics and spintronics applications. In this work, we investigated the effect of an organic molecule (benzene) in close proximity nanoribbon. Our extensive calculations reveal that semiconducting nature stays unaffected as result molecular adsorption while transport properties go through drastic changes. Under influence dopant atoms external strain, colossal changes...
