Abstract Nanomaterials serving as artificial enzymes of the new generation (nanozymes), exhibit enhanced catalytic performance, excellent stability, low cost of production, and other associated properties of nanoparticles. This emerging field of nanozymes has broad‐spectrum potential applications in the bridging area…
Understanding the effect of heteroatoms on the capacitance of doped carbon provides an effective strategy to boost its electrochemical performance. Here we show that the pseudocapacitive behavior is closely related to the chemical sites of bonded oxygen, which can be enhanced by immobilizing oxygen functional groups o…
ABSTRACT In this study, hyperbranched polyether (HBP) with terminal hydroxyl was synthesized from tetrahydrofuran and glycidol by cationic open‐loop polymerization and then modified by 2‐phosphono‐butane‐1,2,4‐tricarboxylic acid to introduce carboxyl and phosphorus to improve corrosion and scale inhibition. The struct…
ABSTRACT Superhydrophobic three‐dimensional porous materials have been considering as one of the most promising candidate absorbents for removal and collection of oil spills or organic contaminants from water. In this work, we report a novel and straightforward method for construction of hierarchical superhydrophobic…
Abstract This study investigates the kinetics of thermally initiated polymerization of aryl cyanates with different bridging fragments ((CH 3 ) 2 C, S, and O). To minimize the effect of impurities on the kinetics, the aryl cyanates are synthesized in a highly pure form. The rates of polymerization are measured by diff…
In this paper, we identify three possible candidate series of half-metals (HM) from Bi-based double perovskites Bi2BB′O6 (BB′ = transition metal ions) through calculations utilizing the density functional theory (DFT) and full-structural optimization, in which the generalized gradient approximation (GGA) and the stron…
Metal-enhanced fluorescence (MEF), resulting from the near-field interaction of fluorophores with metallic nanostructures, has emerged as a powerful tool for dramatically improving the performance of fluorescence-based biomedical applications. Allowing for lower autofluorescence and minimal photoinduced damage, the de…
ABSTRACT Magnetically responsive polymer composites have great potential for use in diverse biomedical applications. In this study, composite biomaterials consisting of silk fibroin (SF) and superparamagnetic iron oxide nanoparticles (SPIONs) were fabricated by the electrospinning method. Two different methods were em…
Cellulose nanofibers are often explored as biobased reinforcement for the production of high-performance composite materials. In this work, we fabricated transparent poly(methyl methacrylate) (PMMA) composites consisting of two-dimensional and three-dimensional bacterial cellulose (BC) nanofiber networks. Three differ…
In thiswork, we investigate the influence of Mn2+ on the emission color, thermal sensing and optical heater behavior of NaGdF4: Yb/Er nanophosphors, which the nanoparticles were synthesized by a hydrothermal method using oleic acid as both a stabilizing and a chelating agent. The morphology and crystal size of upconver…
Surface roughness of metal nanoparticles (NPs) is well-known to play an important role in the quantitative analysis and performance of their surface-enhanced Raman scattering (SERS), but its analogous role in catalysis is not given the due credit yet. In the present work, we systematically investigated this by utilizi…
Finite element modelling (FEM) has been extensively performed to study the flow process, the distribution of hydrostatic stress and the temperature rise in materials processed by high-pressure torsion (HPT). This overview provides a summary and a critical assessment of the most important findings obtained by means of…
Abstract Designing the pore network structure is an effective approach to improve the performance of industrial catalyst particles, although it receives less attention than designing catalytic surfaces or active sites. This work presents a first example of the optimization of catalyst pore network structures in the pr…
Complex cutaneous wounds like diabetic foot ulcers represent a critical clinical challenge and demand a large-scale and low-cost strategy for effective treatment. Herein, we use a rabbit animal model to investigate efficacy of bioactive wound dressings made up of silk biomaterials. Nanofibrous mats of Antheraea assama…
A pentanary chloride sulfate KBiCl 2 SO 4 ( 1 ) is synthesized via a simple solution routine. 1 is crystallized in the chiral orthorhombic P 2 1 2 1 2 1 with Z = 4, and its one-dimensional structure features a {[BiCl 2 (SO 4 )] − } ∞ chain along the polar axis. Its second-harmonic generation response is approximately…
Abstract The device standards necessary for high‐performance carbon nanotube (CNT) field‐effect transistors (FETs) for integrated circuits (ICs) are discussed by illustrating key device metrics. Recent advances in solution‐processed CNT network‐materials are introduced and some important progress made in CNT‐network f…
Reduced dimensionality of structures such as 0D quantum dots, 1D nanorods, and 2D nanoplatelets is predicted to favor the creation of tightly bound excitons stable at room temperature, making experimental determination of the exciton binding energy ( R x ) crucial for evaluating the performance of semiconductor nanopa…
The electrochemical exfoliation of graphite has attracted considerable attention as a method for large-scale, rapid production of graphene and graphene oxide (GO). As exfoliation typically requires direct electrical contact, and is limited by the shape and/or size of the starting graphite, treatment of small graphite…
Abstract Recent work on reactive flash sintering of powders of two oxides, bismuth and of iron oxide, into pure single phase bismuth ferrite, which was accomplished in a few seconds at low furnace temperatures, is expanded to four constituents, alumina, lithia, zirconia, and lanthana, to produce reasonably dense polyc…
Abstract Many studies have shown that Eringen's differential nonlocal model leads to some inconsistencies for the cantilever beams, which indicates the necessity to adopt the original integral nonlocal model. In this paper, Eringen's two‐phase local/nonlocal model is applied to capture the size effect in the curved Eu…
