A hierarchically ordered array of Ag-nanorod bundles is achieved using an inexpensive binary-template-assisted electrodeposition technique. In every bundle, many small gaps are formed between adjacent Ag-nanorods, where "hot spots" are generated. As a result, this plasmonic nanostructure exhibits SERS enhancements of…
Highly transparent and conductive materials are required for many industrial applications. One of the interesting features of ZnO is the possibility to dope it using different elements, hence improving its conductivity. Results concerning the zinc oxide thin films electrodeposited in a zinc perchlorate medium containi…
ZnSnO<sub>3</sub> (ZTO)/Ag/ ZnSnO<sub>3</sub> (ZTO) trilayer films were prepared on glass substrates by radio frequency (RF) and direct current (DC) magnetron sputtering. The electrical resistivity and optical transmittance of the films were investigated as a function of the Ag interlayer thickness. ZTO films with a 1…
Critical adsorption behaviors of flexible copolymer chains tethered to a flat homogeneous surface are studied by using Monte Carlo simulations. We have compared the critical adsorption temperature Tc, estimated by a finite-size scaling method, for different AB copolymer sequences with A the attractive monomer and B th…
The nonlinear response of a ferroic to external fields has been studied for decades, garnering interest for both understanding fundamental physics, as well as technological applications such as memory devices. Yet, the behavior of ferroelectrics at mesoscopic regimes remains poorly understood, and the scale limits of…
Three satellites can be used for global positioning. Similarly, the authors propose using the spins of three nitrogen-vacancy centers in the tip of a diamond nanoprobe as a multipoint quantum sensor, for fast 3D magnetic resonance imaging with subnanometer resolution. This technique offers fast detection of individual…
Ni41.7Ti38.8Nb19.5 shape memory alloy films were sputter-deposited onto silicon substrates and annealed at various temperatures. A narrow thermal hysteresis was obtained in the Ni-Ti-Nb films with a grain size of less than 50 nm. The small grain size, which means an increase in the volume fraction of grain boundaries,…
The assembly and manipulation of charged colloidal particles at oil/water interfaces represent active areas of fundamental and applied research. Previously, we have shown that colloidal particles can spontaneously generate unstable residual charges at the particle/oil interface when spreading solvent is used to disper…
Nanoparticles with high paclitaxel (PTX) loading and low systemic toxicity are prepared in scalable and versatile manner via one-step ring-opening polymerization of a prodrug monomer consisting of PTX that is appended to a cyclic carbonate through a hydrolysable ester linker. Initiating this monomer from a hydrophilic…
In this work, the first experimental results of thermotropic liquid crystals used as phase change materials for thermal storage are presented. For that purpose, the n = 10 derivative from the family of 4′-n-alkoxybiphenyl-4-carboxylic acids has been prepared. Different techniques like polarized-light microscopy, diffe…
Magnesium oxide nanoparticles (MgONP) are predominantly utilized in industrial products. This study was undertaken to elucidate the mechanisms underlying toxic effect of MgONP in human colon cancer (HT 29) cells over 48 hr period. Cytotoxicity was evaluated by using MTT and neutral red uptake assays. Data demonstrated…
Exploring self‐assembled nanostructures with controllable architectures has been a central theme in nanoscience and nanotechnology because of the tantalizing perspective of directly integrating such bottom‐up nanostructures into functional devices. Here, the growth of kinked single‐crystal In 2 O 3 nanostructures cons…
Biodegradable plastics has gained significant commercial interest in recent years as they are having similar properties to that of the synthetic plastic used now a days, they are completely bio-degradable, are produced from natural (microbial) sources and are biocompatible in human system. These properties make PHB as…
Oriental Journal of Chemistry is a peer reviewed quarterly research journal of pure and applied chemistry. It publishes standard research papers in almost all thrust areas of current chemistry of academic and commercial importance. It provides a platform for rapid publication of quality research papers, reviews and ch…
The marine atmosphere corrosion behavior of a low alloy steel with different nickel contents (0, 0.8, 2, 5 wt%) was studied in the alternate wet-dry conditions(dry/wet conditions). The technique of polarization curves, EIS and SEM were used to study the effect of Ni on the corrosion resistance of four steels, which in…
1-butyl-3-methylimidazolium acetate C4mim][CH3COO]/dimethyl sulfoxide/DMSO can effectively dissolve cellulose at ambient temperature without any heating. However, the thermostability, morphology, and structure of cellulose regenerated from the [C4mim][CH3COO]/DMSO solvent is little known. Therefore, in this work, the…
Observation of Auger electron emission from Al under the impact of He ions, at energies below the excitation threshold of Al-Al collisions, gives evidence for charge transfer in He-Al collisions. Excitation of $2p$-shell electrons in Al is produced by vacancy transfer, following double excitation of He by promotion of…
The adsorption of water on solid surfaces is a scientific evergreen which again recently prompted considerable attention in the materials, nano-, and surface science communities, respectively, due to conflicting evidence presented in the most highly regarded scientific journals. This mini review is a brief and persona…
Low‐energy recoil events in Ti 3 SiC 2 are studied using ab initio molecular dynamics simulations. We find that the threshold displacement energies are orientation dependent because of anisotropic structural and/or bonding characteristic. For Ti and Si in the Ti–Si layer with weak bonds that have mixed covalent, ionic…
Oxygen vacancies in ${\mathrm{LaAlO}}_{3}$ (LAO) play an important role in the formation of the two-dimensional electron gas observed at the ${\mathrm{LaAlO}}_{3}\text{/}{\mathrm{SrTiO}}_{3}$ interface and affect the performance of MOSFETs using LAO as a gate dielectric. However, their spectroscopic properties are sti…
