The dissipative particle dynamics (DPD) simulation technique is a coarse-grained (CG) molecular dynamics-based approach that can effectively capture the hydrodynamics of complex systems while retaining essential information about the structural properties of the molecular species. An advantageous feature of DPD is tha…
A promising material for catalysis should have appropriate band edge positions. Unfortunately, the band edge positions are unknown for nickel oxyhydroxide (NiOOH), one of the best water oxidation catalysts. We present here first-principles calculations of band edge positions for surfaces of pure NiOOH. Specifically, t…
A zirconia/oligosiloxane nanocomposite encapsulant has been developed and tested in a high-power LED package against commercial silicone resins. The composite was a marriage of zirconia nanocrystals modified with butyric acid (BA) and 3-methacryloxy propyl trimethoxysilane (MPTMS) and a high-index methacryloxy-oligosi…
BACKGROUND: Nanodiamonds are one of the most perspective nano-sized particles with superb physical and chemical properties, which are mainly composed of carbon sp(3) structures in the core with sp(2) and disorder/defect carbons on the surface. The research team recently demonstrated neuromodulatory properties of carbo…
The nanostructuring approach has significantly contributed to the improving of thermoelectric figure‐of‐merit ( ZT ) by reducing lattice thermal conductivity. Even though it is an effective method to enhance ZT , the drastically lowered thermal conductivity in some cases can cause thermomechanical issues leading to de…
Abstract The concentration of helium in tungsten fuzz-like nanostructures has been measured by means of thermal desorption spectroscopy. Fuzz was formed on the W surface under intensive plasma irradiation at 1500 K. The helium content was measured first in the as-irradiated sample, and then in a similar sample with th…
Silk cocoons are composed of fiber proteins (fibroins) and adhesive glue proteins (sericins), which provide a physical barrier to protect the inside pupa. Moreover, other proteins were identified in the cocoon silk, many of which are immune related proteins. In this study, we extracted proteins from the silkworm cocoo…
Disordered carbon materials, both amorphous and with long-range order, have been used in a variety of applications, from conductive additives and contact materials to transistors and photovoltaics. Here we show a flexible solution-based method of preparing thin films with tunable electrical properties from suspensions…
The volumetric redox (chemical) capacitance of the surface of CeO2-δ films is quantified in situ to be 100-fold larger than the bulk values under catalytically relevant conditions. Sm addition slightly lowers the surface oxygen nonstoichiometry, but effects a 10-fold enhancement in surface chemical capacitance by miti…
A new class of leaf stalk fibers of the palm tree were extracted and treated with a 5% NaOH solution for 1 h, 2 h, 6 h, and 12 h. The treated fibers were then characterized by tensile strength testing, chemical analysis, Xray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microsco…
ABSTRACT Carvacrol and p ‐cymene are sustainable and versatile starting materials for the preparation of hydrophobic monomers. These molecules can be readily derived from pine resin or produced from other sustainable feedstocks via a biosynthetic approach. A hydrophobic epoxy monomer [bis(2‐isopropyl‐5‐methyl‐4‐(oxira…
In the present work, two-armed macroinitiator containing coumarin were synthesized, characterized by Fourier transform infrared spectroscopy and 1 H nuclear magnetic resonance techniques and investigated theoretically using density functional theory (DFT) calculations. The molecular geometry, fundamental vibrational f…
Inkjet printing technology has brought significant advances in patterning various functional materials that can meet important challenges in personalized medical treatments. Indeed, patterning of photothermal active anisotropic gold nanoparticles is particularly promising for the development of low-cost tools for loca…
Monolayer molybdenum disulfide (MoS2) has recently attracted intense interests due to its remarkable optical properties of valley-selected optical response, strong nonlinear wave mixing and photocurrent/photovoltaic generation and many corresponding potential applications. However, the nature of atomic-thin thickness…
We describe a straightforward strategy for a new family of functional polycaprolactones (PCL) via the Passerini multicomponent polymerization (P-MCP) of 6-oxohexanoic acid and various isocyanides. Room temperature polymerization of tert -butyl isocyanide ( 1 ), 2,6-dimethylphenyl isocyanide ( 2 ), mOEG4 isocyanide ( 3…
Petroselinic acid, a positional isomer of oleic acid, was isolated from the vegetable oil of Coriandrum sativum fruits. This uncommon fatty acid was subsequently used as substrate for sophorolipid fermentation with a Starmerella bombicola lactone esterase overexpression (oe sble) strain. A petroselinic acid based diac…
Nickel nanoparticles were synthesized and used to decolourize dye effluent. C. I. Reactive Blue 21 was taken as a reference dye, and polyvinyl pyrrolidone (PVP) was used as a stabilizer to prevent agglomeration of nanoparticles. Characterization of nanoparticles was done by a laser light scattering particle size analy…
Abstract Nowadays polymer nanocomposites represent an important stake in scientific research and offer a combination of properties with respect to single components. The present work deals with nanocomposite hydrogels obtained from alginate, a biobased polymer, which is employed as a biocompatible matrix for the encap…
The intrinsic zinc oxide (ZnO) thin films with controllable crystallographic orientation have been synthesized on Si(100) substrates using plasma-enhanced chemical vapor deposition (PECVD) system without any buffer layer. Based on X-ray diffraction (XRD) results, the evolution of crystallographic orientation of ZnO th…
Generating a single material with multiple ferroic properties has been the hotspot of research interest for decades. The existing studies mostly focus on the intrinsic properties of multiferroic materials, overlooking the importance of the widely distributed defects in the materials. Here, the strong influence of oxyg…
