Mixed nickel–iron oxides have recently emerged as promising electrocatalysts for water oxidation because of their low cost and high activity, but the composition and structure of the catalyst’s active phase under working conditions are not yet fully established. We present here density functional theory calculations w…
The light‐harvesting Sb2S3 surface on mesoporous‐TiO2 in inorganic–organic heterojunction solar cells is sulfurized with thioacetamide (TA). The photovoltaic performances are compared before and after TA treatment, and the state of the Sb2S3 is investigated by X‐ray diffraction, X‐ray photoelectron spectroscopy, and d…
Our goal was to gain a better understanding of the contribution of the burial of polar groups and their hydrogen bonds to the conformational stability of proteins. We measured the change in stability, Δ(ΔG), for a series of hydrogen bonding mutants in four proteins: villin headpiece subdomain (VHP) containing 36 resid…
We report photovoltaic performances of all-solid state Sn/Pb halide-based perovskite solar cells. The cell has the following composition: F-doped SnO2 layered glass/compact titania layer/porous titania layer/CH3NH3SnxPb(1-x)I3/regioregular poly(3-hexylthiophene-2,5-diyl). Sn halide perovskite itself did not show photo…
Biosensors based on field-effect transistors (FETs) have attracted much attention, as they offer rapid, inexpensive, and label-free detection. While the low sensitivity of FET biosensors based on bulk 3D structures has been overcome by using 1D structures (nanotubes/nanowires), the latter face severe fabrication chall…
Water adsorption in porous materials is important for many applications such as dehumidification, thermal batteries, and delivery of drinking water in remote areas. In this study, we have identified three criteria for achieving high performing porous materials for water adsorption. These criteria deal with condensatio…
This research investigates the properties of sulfathiazole-based poly(urethane urea) with silver ions connected to the main chain. The polyurethane prepolymer was prepared from 1,6-hexane diisocyanate and poly(tetramethy1ene oxide) glycol. The formation of the polyurethane was investigated through FTIR, and the mechan…
Because there are different pathways to grow carbon nanotubes (CNTs), a common mechanism for the synthesis of CNTs does not likely exist. However, after carbon atoms are liberated from carbon-containing precursors by catalysts or from pure carbon systems, a common feature, the nucleation of CNTs by electron mediation,…
Two AB-type monomers 4-fluoro -N-(4-(2-(4-hydroxyphenyl) propan-2-yl) phenyl) benzamide and 4-fluoro -N-(5-hydroxy naphthyl) benzamide were synthesized. The AB-type poly(ether-amide)s (PEAs) were derived by self-polymerization via the nucleophilic aromatic displacement reaction of AB-type monomers. The structure of AB…
Spontaneous patterning of anisotropic nanostructures into ordered assemblies remains a challenging quest, which requires controlled innovative approaches. One way to achieve such ordering of 1D nanorods is by manipulating the varieties of interactions (attractive and repulsive forces) present in colloidal solutions of…
The ferroelectric properties of the BiFeO3/La0.625Ca0.375MnO3 (BFO/LCMO) heterostructures were investigated using different bottom electrode configurations at different magnetic fields and temperatures. It is found that the apparent coercive voltage (Vac) increases linearly with the increase of LCMO resistances for di…
We have investigated the effects of post-thermal annealing on the resistive switching characteristics of dielectric/ferroelectric composite devices of SrRuO3/LaFeO3/Bi1−δFeO3/SrRuO3. Annealing of the devices above 85 °C enhanced the hysteresis of the current–voltage characteristics, resulting in an increase in the res…

Abstract In‐situ doped polyaniline nanotubes were fabricated and investigated in term of their morphological, thermal and electrical properties at varied doping levels. Different from the common post‐doping of polyaniline base to form its emeraldine salt, the aniline monomers were directly converted into conductive em…
We present a novel approach, based on image analysis and modelling, to study the impact of morphological variability (roughness) and fluid dynamics on substrate mass fluxes in biofilms. Specifically, we used this method to assess substrate fluxes in counter-diffusional autotrophic biofilms in a hydrogen-based membrane…
Lead-based melts (Pb, Pb-Bi) are considered as candidate coolants and spallation neutron targets due to their excellent thermophysical and nuclear properties. However, the corrosion of structural materials remains a major issue. Oxide dispersion strengthened (ODS) ferritic/martensitic steels are considered for high te…
The effect of chiral angle independent from diameter on tensile behavior of single-walled carbon nanotubes (SWCNTs) is studied. Two methods in finite element continuum mechanics modeling of SWCNTs are used. The role of chiral angle and diameter are investigated independently on linear and nonlinear tensile behavior of…
Thermoplastic vulcanizates (TPVs) based on high impact polystyrene (HIPS)/high vinyl polybutadiene rubber (HVPBR) composites were prepared by dynamic vulcanization, and then compatibilized by styrene–butadiene–styrene (SBS) block copolymer. The effects of SBS compatibilizer on mechanical properties, Mullins effect, mo…
We report the results of action-derived molecular dynamics simulations for the migration and coalescence processes of monovacancies in graphene and carbon nanotubes with different chiralities. In carbon nanotubes, the migration pathways and barriers of a monovacancy depend on the tube chirality, while there is no pref…
Nearly half of lanthanum sites in lanthanum manganites were substituted with monovalent ion-sodium and the compound possessed distorted orthorhombic structure. Ferromagnetic ordering at 300K and the magnetic isotherms at different temperature ranges were analyzed for estimating magnetic entropy variation. Magnetic ent…
