Electrospinning is one of the efficient processes to fabricate polymeric fibrous scaffolds for several biomedical applications. Several studies have published to demonstrate drug release from electrospun scaffolds. Blends of natural and synthetic electrospun fibers provide excellent platform to combine mechanical and…
Graphene field-effect transistors (FETs) capped with ionophore were fabricated to demonstrate the highly sensitive and selective detection of Hg (II) ions in solution. We systematically investigated the ion detection performances and sensing mechanism of this 2D material. Due to its ambipolar nature, graphene can work…
We report the effect of Al2O3 encapsulation on the carrier mobility and contact resistance of multilayer MoS2 thin-film transistors by statistically investigating 70 devices with SiO2 bottom-gate dielectric. After Al2O3 encapsulation by atomic layer deposition, calculation based on Y-function method indicates that the…
Monolayer transition-metal dichalcogenides (1L-TMDs) are atomically thin direct band gap semiconductors, from which the emission of light is determined by optical transitions of exciton complexes such as neutral excitons and trions. While the quantum yields of 1L-TMDs are quite low, the ability to control the populati…
With the goal to push the mechanical properties of reconfigurable supramolecular polymers toward those of thermoset resins, we prepared and investigated a new family of hydrogen-bonded polymer networks that are assembled from isophthalic acid-terminated oligo(bisphenol A- co -epichlorohydrin) and different bipyridines…
Rhenium diboride (ReB 2 ), containing corrugated layers of covalently bonded boron, is a superhard metallic compound with a microhardness reaching as high as 40.5 GPa (under an applied load of 0.49 N). Tungsten diboride (WB 2 ), which takes a structural hybrid between that of ReB 2 and AlB 2, where half of the boron l…
This short review discusses the classification, pressure concentration isotherm (PCI) characterisation and applications of metal hydrides. Special attention is paid to describe the design criterion and fabrication of Sievert's apparatus and PCI characterisation methods of metal hydrides. Different classes of metal hyd…
In this study, we develop a completely green process that could generate a recycled and value added product of polystyrene (PS), such as micro- and nanosized particles, from waste expanded PS (EPS). The process uses the eco-friendly solvent, d -limonene for dissolving waste EPS. We show the first time use of water as…
In the present study, the morphological changes on a gold electrode during the oxygen reduction (ORR) and oxygen evolution reaction (OER) processes in a dimethyl sulfoxide (DMSO)-based electrolyte solution were investigated using an electrochemical atomic force microscope (EC-AFM) with the help of vibrational spectros…
Perfect light absorption over wide angles is possible in a multilayer structure, including Au or Ni metal and Ge2Sb2Te5 (GST) phase change material, without the need of sophisticated lithography. The GST layer also permits deep modulation of the absorption when it undergoes a phase transition.
Abstract Atomic layer deposition (ALD) of ultrathin aluminum oxide (AlOx) films was systematically studied on supported chemical vapor deposition (CVD) graphene. We show that by extending the precursor residence time, using either a multiple-pulse sequence or a soaking period, ultrathin continuous AlOx films can be ac…
The simultaneous study on photoelectrochemical CO 2 reduction with Brilliant Green (BG) dye removal was studied in the present work. Experimental studies were done in aqueous solutions of sodium and potassium based electrolytes using a cathode [Zinc (Zn) and Tin (Sn)] and a common cobalt oxide (Co 3 O 4 ) anode electr…
Chitosan (CHI), a biocompatible and biodegradable polysaccharide with the ability to provide a non-protein matrix for tissue growth, is considered to be an ideal material in the biomedical field. However, the lack of good mechanical properties limits its applications. In order to overcome this drawback, CHI has been c…
Selective adhesion and migration of endothelial cells (ECs) over smooth muscle cells (SMCs) is very important in the rapid endothelialization of blood-contacting implants to prevent vascular restenosis. In this study, a uniform cell-resistant layer of methacrylate-functionalized hyaluronic acid (HA) was first immobili…
With its superior electrical, optical, thermal, and mechanical properties, graphene offers a versatile platform for fabricating innovative hybrid composite materials with diverse potential applications. The preparation of graphene-based composites, particularly as thin films with nanoscale precision, is highly importa…
Abstract Cuprate high-temperature superconductors consist of two quasi-two-dimensional (2D) substructures: CuO 2 superconducting layers and charge reservoir layers. The superconductivity is realized by charge transfer from the charge reservoir layers into the superconducting layers without chemical dopants and defects…
The current research explores the use of halloysite nanotube as a multifunctional filler in epoxy coating for carbon steel. Epoxy monomer loaded halloysite was incorporated into epoxy coating along with amine hardener immobilized mesoporous silica. The waterproofing, self-healing, anticorrosive abilities, and stabilit…
A novel approach to on-demand improvement of electronic properties in complex-oxide ferroelectrics is demonstrated whereby ion bombardment – commonly used in classic semiconductor materials – is applied to the PbTiO3 system. The result is deterministic reduction in leakage currents by 5 orders of magnitude, improved f…
For commercial applications, the need for smaller footprint energy storage devices requires more energy to be stored per unit area. Carbon nanomaterials, especially graphene, have been studied as supercapacitor electrodes and can achieve high gravimetric capacities affording high gravimetric energy densities. However,…
With the help of a technique combining in situ electrical impedance spectroscopy and DRIFT spectroscopy, we observed directly the formation of ammonium ion (NH 4 + ) intermediates resulting from the interaction of NO and NH 3 on Fe-ZSM-5 catalysts for selective catalytic reduction by NH 3 (NH 3 –SCR). The formed NH 4…
