Broadband second-harmonic (SH) and sum-frequency generation was studied in KH 2 PO 4 crystals with incorporated anatase modification of titania nanocrystals. A tiny amount (10 −5 wt.%) of titania nanoparticles in the anatase phase exhibits a pronounced (up to 15%) increase of the SH efficiency in comparison with the n…
Purpose – This work aimed to study the effect of environment resistivity and distance between cathode and anode on the required cathodic protection current density of buried carbon steel pipes and determine the impressed current that gives full protection to bare and coated pipes by two different coatings. Design/meth…
In this research, N-substituted polyaniline was synthesized by chlorine-terminated chloroacetyl chloride incorporation and methylmethacrylate polymerization done onto the leucoemeraldine. The authors prepared polyaniline-graft-polymethylmethacrylate copolymer by methylmethacrylate ATRP using polyaniline macroinitiator…
Resonant magnetic x-ray scattering at the Gd L 2 edge is used to investigate the magnetic order of the Gd moments in the ferroelectric phase of multiferroic GdMnO 3 at low temperatures and under magnetic fields. Our findings reaffirm the important role of the Gd moments in the symmetric magnetic exchange striction res…
Abstract PtM/Ba/ACZ (M=Mn, Fe, and Co) and Pt/Ba/ACZ were prepared using Al2O3Ce0.6Zr0.4O2 (ACZ) as a support. XRD analysis shows Ce0.6Zr0.4O2 solid solution was formed in the ACZ support, and M addition results in a slight shift of the characteristic peaks of Ce0.6Zr0.4O2 to higher 2θ value. A strong interaction be…
We present a molecular dynamics study on the stretching of a linear polymer chain that is adsorbed at the junction of two intersecting flat surfaces of varying alignments. We observe a transition from a two-dimensional to one-dimensional (1D) structure of the adsorbed polymer when the alignment, i.e., the angle betwee…
Biofunctional surface patterns capable of resisting nonspecific bioadsorption while retaining bioactivity play crucial roles in the advancement of life science and biomedical technologies. The currently available functional surface coatings suffer from a high level of nonspecific surface adsorption of proteins under b…

We investigate the phase sequence of biaxial liquid crystals, based on a general quadratic model Hamiltonian over the relevant parameter space, with a Monte Carlo simulation which constructs equilibrium ensembles of microstates, overcoming possible (free) energy barriers (combining entropic and frontier sampling techn…
This figure shows the shape recovery ratio as a function of thermo-mechanical training cycles when 304 stainless steel are deformed by 1.7% at 77 K. It shows that the thermo-mechanical training consisting of deformation at 178 K and subsequent annealing at 933 K remarkably enhances the shape memory effect of 304 stain…
We have investigated the dielectric performances and mechanism of super-thin Mn-doped Pb(Mg1/3Nb2/3)O3-PbTiO3 crystals, exhibiting significantly different dielectric behaviors compared with thick wafer. Dramatic decrease by 5 times and large frequency dispersion of permittivity, changed diffuse degree of phase transit…
A basic compound, called a quencher, plays an important role in the formation of latent images in chemically amplified resists. In this study, the effect of photodecomposable quenchers on latent image quality was investigated using a simulation on the basis of the reaction mechanisms of chemically amplified extreme ul…
We report observations of space-group-forbidden Bragg reflections in Potassium (KH 2 PO 4 ), at the potassium K edge. We find clear evidence for a transition from one class of space-group-forbidden reflections, where scattering is ruled out by the electric dipole approximation, to a second class, in the ferroelectric…
Radiation patterns from plasmonic nano-antennas formed on a glass substrate were investigated using index-matching oils. It was confirmed that the pattern from single nano-antennas for various cases of index-mismatching between the substrate and the oil is explained well by the patterns of infinitesimal electric dipol…
Purpose – This study aims to study electrochemically and by weight-loss experiments the effect of UAE Rhazya Stricta Decne extract on the corrosion inhibition of mild steel in 1.0 M HCl solution, which will serve researchers in the field of corrosion. Design/methodology/approach – Weight loss measurements were carried…
Experimental studies of the response of Pt/Ba0.3Sr0.7TiO3/Cu capacitors to switching-off the bias voltage are reported. The remnant capacitance as a function of the bias voltage and the variation of this capacitance with time have been measured and analyzed in terms of the injection model of the space charge origin wi…
Abstract The local, deterministic optimisation algorithm BOBYQA (bound optimisation by quadratic approximation) was applied for the computer‐assisted optimisation of inorganic–organic hybrid compounds. Four proof‐of‐concept studies were performed: 1) increasing the crystallinity and 2) inhibiting the crystallisation o…

In this study, the influences of initial settings, i.e. initial conformations, configurations and docking parameters, on docking results were investigated. The conformations used in the study were generated by the CAMDAS program. After the conformational search calculations, five structures were selected from the conf…
Abstract A versatile method is described to synthesize a new family of solvent‐responsive membranes whose response states can be not only tunable but also fixable via ultraviolet (UV) irradiation induced crosslinking. The atom transfer radical polymerization (ATRP) initiator 2‐bromoisobutyryl bromide was first immobil…
