N -Butyl N -carboxyanhydride (Bu-NCA) was polymerized in THF to produce poly( N -butylglycine) using benzyl alcohol initiator and 1,1,3,3-tetramethylguanidine (TMG) promoter. Poly( N -butylglycine) species (PNBG) with controlled molecular weight ( M n = 2.9–20.5 kg mol –1 ) and narrow molecular weight distribution (PD…
Employing density functional theory--based methods, we investigate monolayer and bilayer structures of hexagonal ${\mathrm{SnS}}_{2}$, which is a recently synthesized monolayer metal dichalcogenide. Comparison of the $1H$ and $1T$ phases of monolayer ${\mathrm{SnS}}_{2}$ confirms the ground state to be the $1T$ phase.…

The effect of the A-site cation ordering on the chemical stability, oxygen stoichiometry and electrical conductivity in layered LaBaCo2O5+δ double perovskite was studied as a function of temperature and partial pressure of oxygen. Tetragonal A-site cation ordered layered LaBaCo2O5+δ double perovskite was obtained by a…
Antimicrobial efficacy of nickel nanoparticles synthesized using leaf extract of Ocimum sanctum (NiGs) was investigated against pathogenic Gram-negative ( E. coli , K. pneumoniae , and S. typhi ), Gram-positive ( B. subtilis , S. epidermidis ) bacteria and fungi ( C. albicans , C. tropicalis, A. fumigatus , A. clavatu…
Chemoprevention of human cancer by dietary products is a practical approach of cancer control, especially when chemoprevention is involved during the early stages of the carcinogenesis process. Research over the last few decades has clearly demonstrated the efficacy of dietary products for chemoprevention in cell cult…
Promotion of cell adhesion on biomaterials is crucial for the long-term success of a titanium implant. Herein a novel concept is highlighted combining very stable and affine titanium surface adhesive properties with specific cell binding moieties in one molecule. A peptide containing L-3,4-dihydroxyphenylalanine was s…
We experimentally studied the built-in polarization induced effective piezoelectric constant and direct flexoelectric coefficient in α-phase bulk polyvinylidene fluoride (PVDF). This phenomenon was detected and discussed based on the compression of a truncated cone. An improved mechanical formulation of flexoelectrici…
In this review, we present an extensive summary of research on superhydrophobic electrodeposits reported in the literature over the past decade. As a synthesis technique, electrodeposition is a simple and scalable process to produce non-wetting metal surfaces. There are three main categories of superhydrophobic surfac…
Inspired by the wax regeneration ability of plant leaves and the slippery surfaces of the Nepenthes pitcher plants, we have developed a new form of cross-species bioinspired slippery liquid-infused porous surfaces (X-SLIPS) that can self-repair under thermal stimulation even under large-area physical and chemical dama…
A group of new polymolybdates was synthesized and tested in the catalytic oxidation of cycloalkanes. Investigated compounds exhibit broad structural diversity including polymolybdates with isolated anionic clusters (0-dim), polymeric anions (1-dim), Mo–O layers (2-dim) as well as hexagonal and orthorhombic molybdenum…
Operando characterization of gas-solid reactions at the atomic scale is of great importance for determining the mechanism of catalysis. This is especially true in the study of heterostructures because of structural correlation between the different parts. However, such experiments are challenging and have rarely been…
The aim of this present investigation was to identify a new natural fiber from one of the cotton plant’s byproducts, which is chemically modified by alkaline treatment. Its characteristics were examined for the preparation of natural fiber–reinforced polymer composites. The cotton shell fibers (CSFs) were extracted fr…
Interfacial polyelectrolyte (polyion) complexation (IPC) is a process whereby fibers and capsules are formed through interactions at the interface of oppositely charged polymers. Since its discovery in the late 1990s, the IPC fiber process, in particular, has been investigated for various applications such as tissue e…
In this work, we present a facile and low-cost approach to synthesize heteroatom doped porous carbon via hydrothermal treatment of stem bark of broussonetia papyrifera (BP) as the biomass precursor in diluted sulfuric acid, and following thermal activation by KOH at 800 °C. The morphology, structure and textural prope…
In the present work, silver nanoparticles were in situ-generated in cellulose matrix using Ocimum sanctum leaf extract as a reducing agent. Regenerated wet cellulose films were first immersed in O. sanctum leaf extract and then it was allowed to diffuse into the films. The leaf extract–diffused wet films were dipped i…
Excitation of the collinear compensated antiferromagnet DyFeO_{3} with a single 60 fs laser pulse triggers a phase transition across the Morin point into a noncollinear spin state with a net magnetization. Time-resolved imaging of the magnetization dynamics of this process reveals that the pulse first excites the spin…
The intentional design of chemical architecture of lanthanide doped luminescent nanoparticles through the proper selection of dopants in core–shell and core–shell–shell structures enables optimization of their optical properties. Such an approach allows one to achieve energy transfer up-conversion (ETU) and energy mig…
High-performance electronics requires the fine control of semiconductor conductivity. In atomically thin two-dimensional (2D) materials, traditional doping technique for controlling carrier concentration and carrier type may cause crystal damage and significant mobility reduction. Contact engineering for tuning carrie…
Drug-coated sutures are widely used as delivery depots for antibiotics and anti-inflammatory drugs at surgical wound sites. Although drug-laden coating provides good localized drug concentration, variable loading efficiency and release kinetics limits its use. Alternatively, drug incorporation within suture matrices i…
