Blue-tailed forest hawk dragonfly ( Orthetrum triangulare ) wings exhibit a high transparency at wide viewing angles. The broadband omnidirectional antireflection behaviors of dragonfly wings result from the random arrangement of inclined irregular conical structures. In this study, a scalable colloidal lithography te…
Strong-stability-preserving (SSP) implicit–explicit (IMEX) Runge–Kutta (RK) methods for the Cahn–Hilliard (CH) equation with a polynomial double-well free energy density were presented in a previous work, specifically H. Song’s “Energy SSP-IMEX Runge–Kutta Methods for the Cahn–Hilliard Equation” (2016). A linear conve…
A rapid, simple, and cheap colorimetric nanosensor for indirect measurement of hydrophilic and lipophilic antioxidant activity using mixed-valence MnO <sub>x</sub> NPs as an oxidase-mimicking catalyst was proposed.
Two sandwich-type germanomolybdates with unprecedented trivacant [α-GeMo <sub>10</sub> O <sub>36</sub> ] <sup>8−</sup> fragments and {M <sub>3</sub> O <sub>4</sub> } quasi-cubane units were obtained. They exhibited electrocatalytic behaviours for H <sub>2</sub> O <sub>2</sub> reduction and photocatalytic properties fo…
Abstract Hetero-nanostructures based on magnetic contrast oxides have been prepared as highly dense nanoconsolidates. Cobalt ferrite-cobalt oxide core-shell type nanoparticles (NPs) were synthesized by seed mediated growth in polyol and subsequently consolidated by Spark Plasma Sintering (SPS) at 500 °C for a few minu…
Many disinfection technologies have emerged recently in water treatment industry, which are designed to inactivate water pathogens with extraordinary efficiency and minimum side effects and costs. Current disinfection processes, including chlorination, ozonation, UV irradiation, and so on, have their inherent drawback…
Abstract Research of swim bladders on many species revealed that this organ has a high protein content that very potential as a source of collagen. This research aimed to isolate collagen from swim bladders of grouper, convert it into nano collagen, and determine the conformity of collagen with the quality standard of…
The amplification effect of polyoxometalates (POMs) on the efficiency of dye-sensitized nano-ITO cathodes is disclosed. The use of hybrid polyoxometalates of the type [PW 11 O 39 {SnC 6 H 4 ≡C 6 H 4 F}] 4–, F standing for a carboxylic group (POM-COOH) or a diazonium unit, allows control of the loading of the POMs on t…
Abstract Epoxy resin (EP) is extremely flammable, and smoke release during combusting is considered toxic and harmful for human health. Mesoporous materials offer reliable desorption performance due to their large specific surface area. Therefore, the construction of mesoporous nanocomposites is a novel method for enh…
CeO <sub>2</sub> NPs could be transferred along a lettuce–hornworm–chicken terrestrial food chain, and the transformation of CeO <sub>2</sub> NPs depended on the organisms within food chains.
The aim of this study is the analyze the structure of branched polyurethanes based on synthetic poly([R,S]-3-hydroxybutyrate) and their blends with biopolymers and montmorillonite. The properties which would predict the potential susceptibility of these materials to degradation are also estimated. Fourier-transform in…
Abstract The atomic or molecular assembly on 2D materials through the relatively weak van der Waals interaction is quite different from the conventional heteroepitaxy and may result in unique growth behaviors. Here, it is shown that straight 1D cyanide chains display universal epitaxy on hexagonal 2D materials. A univ…
Iron detection is one of the critical markers to diagnose multiple blood-related disorders that correspond to various biological dysfunctions. The currently available anemia detection approach can be used only for pre-treated blood samples that interfere with the actual iron level in blood. Real-time detection approac…
To investigate the relationship between the charge redistribution and ferromagnetism at the interface between perovskite transition-metal oxides $\mathrm{LaNi}{\mathrm{O}}_{3}$ (LNO) and $\mathrm{LaMn}{\mathrm{O}}_{3}$ (LMO), we performed x-ray absorption spectroscopy (XAS) and x-ray magnetic circular dichroism (XMCD)…
Natural fiber-reinforced composites gained considerable interest in the scientific community due to their eco-friendly nature, cost-effective, and excellent mechanical properties. Here, we reported a chemical modification of kenaf fiber using propionic anhydride to enhance the compatibility with the epoxy matrix. The…
Understanding of polymorphism of organic semiconducting materials is the key to structural control of their electrical and mechanical properties. Motivated by the ambipolar n-type charge transport and electroluminescence of thienopyrrolyldione end-capped oligothiophenes, here we studied the propensity of one represent…
Among thermoelectric materials, tin telluride has been attracting significant interest for its nontoxic and eco-friendly nature. Meanwhile, band engineering and ultrathin film technologies have been reported to be promising in improving the performance of thermoelectric materials. In this work, we explore the potentia…
Development of antimicrobial surfaces for sterilization is much needed to avoid the spreading of drug resistant bacteria. Light can activate antimicrobial surfaces by an interaction between nanoparticles and a photosensitizer dye to produce a steady and efficient killing of bacteria. The film studied in this work cont…
ABSTRACT In this work, segmented waterborne polyurethane‐urea (WBPUU) dispersions containing hydrophobic polycaprolactone (PCL) and hydrophilic poly(ethylene glycol) (PEG) in different molar ratios are synthesized and used for the subsequent preparation of films by casting. The molar ratio of PEG is gradually increase…
Rational synthesis of extended arrays of organic matter in bulk, solution, crystals, and thin films has always been a paramount goal of chemistry. The classical synthetic tools to obtain long-range regularity are, however, limited to noncovalent interactions, which usually yield structurally more random products. Henc…
