Density functional theory (DFT) calculations have been performed to study the water–gas shift (WGS) reaction mechanism via the formation of a carboxyl (COOH) intermediate over a low-loaded Ni/CeO 2 (111) model catalyst for which adatoms and tiny clusters of nickel are in direct contact with the ceria support. Strong m…
A new metamaterial absorber (MA) having distinct properties than those given in the literature is investigated. Although several designs have been studied for achieving absorption characteristics in single-band, dual-band and multiple bands within the whole spectrum of solar light, there has been limited number of res…
Abstract To solve the Ti implants-associated infection and poor osseointegration problems, we have constructed the AgNPs/gentamicin (Gen)-loaded silk fibroin (SF) coating with acceptable antibacterial and osteogenic aptitude. Nevertheless, due to uncontrollably sustained drug release, this bactericidal coating encount…
ABSTRACT Paper presents low water vapor barrier capacity that is considered a limitation for its use in packaging applications. Therefore, the effect of using polyhydroxybutyrate (PHB)‐based coatings containing a plasticizer [Tributyrin (TB)] and cellulose nanocrystals (CNCs) in a bilayer configuration with paperboard…
A convenient and direct approach has been developed for the preparation of pyrazole derivatives by the condensation cyclization of hydrazines/hydrazide and 1,3‐diketones in the presence of Cu 1.5 PMo 12 O 40 (0.33 mol%) under mild conditions (r.t.‐60 °C, 10–30 min). Notably, the reaction was found to be scalable as 99…
Owing to their exquisite geometric structures and excellent mechanical properties, spider orb webs possess an outstanding ability to capture flying prey. In this work, we report a mechanism that enhances the energy absorption ability of spider webs. Through systematic measurements of the mechanical properties of both…
High-frequency array transducers can provide higher imaging resolution than traditional transducers, thus resolving smaller features and producing finer images. Commercially available ultrasonic transducers are mostly made with lead-based piezoelectric materials, which are harmful to the environment and public health.…
The onset of important power system problems can be assessed in part by experience from contemporary geomagnetic storms. Power networks are operated using what is termed an “N–1” operation criterion. That is, the system must always be operated to withstand the next credible disturbance contingency without causing a ca…
Abstract Peptide self‐assembly, inspired by the naturally occurring fabrication principle, remains the most attractive in constructing fluorescent nanoagents towards bioimaging. However, the noncovalent interactions that drive peptide self‐assembly are usually susceptible to the complex physiological environment; thus…
Superparamagnetic iron oxide nanoparticles (SPIO-NPs) have great potential to be used in different pharmaceutical applications, due to their unique and versatile physical and chemical properties. The aim of this study was to quantify in vitro cytotoxicity of dextran 70,000-coated SPIO-NPs labelled/unlabelled with rhod…
Dimensionality and orientation of hexagonal boron nitride (h-BN) nanosheets are promising to create and control their unique properties for diverse applications. However, low-temperature deposition of vertically oriented h-BN nanosheets is a significant challenge. Here we report on the low-temperature plasma synthesis…
Flat panel photodetectors have been well studied for their applications in large area detection such as indirect-conversion X-ray imaging. Even though a few of photodetectors have become commercially available, there is still a room for advancement in responsive wavelength range and sensitivity. This paper reports a s…
Abstract Over the past decade, nano‐graphene has emerged as one of the miraculous materials to mankind because of its outstanding electronic, optical, thermal, and mechanical properties. Unique characteristics of nano‐graphene make it more attractive for development of new metal‐free green heterogeneous catalysts espe…
The effective surface tension (γeff) of liquid marbles is a frequently used, but perplexing concept and clarifying this tension has been challenging, mainly due to difficulties in controlling affecting factors from marble surface particles, including particle agglomeration and areal particle density. In this study, we…
We study the optical properties of MoS2 nanotubes (NTs) with walls comprising dozens of monolayers. We reveal strong peaks in micro-photoluminescence (μ-PL) spectra when detecting the light polarized along the NT axis. We develop a model describing the optical properties of the nanotubes acting as optical resonators w…
VO 2 /PNIPAm hybrid thermochromic material has been verified as promising to improve optical performance of smart windows. However, VO 2 can be easily oxidized especially when being dispersed in the hydrogel matrix, and also the nonuniform dispersion of VO 2 in a host will worsen the material’s optical performance. He…
Abstract Single‐composition Ba 2 Y 2 Si 4 O 13 :Bi 3+ ,Eu 3+ (BYSO:Bi 3+ ,Eu 3+ ) phosphors with color‐tunable and white emission were prepared by conventional high temperature solid‐state reaction method. The structural and luminescent properties of these phosphors were thoroughly investigated through X‐ray diffracti…
Spin gapless semiconductors, also known a special class of half-metallic magnets, have received more and more attention in spintronic applications due to the complete spin polarization and the electrical conductivity between half-metals and semiconductors. Motivated by the recent synthesis of spin gapless semiconducto…
ABSTRACT Conducting polymer‐chalcogenide composites have recently been used as propitious contenders for light‐weight, cost‐saving, and nonhazardous thermoelectric (TE) applications. In this work, polyaniline‐bismuth selenide (PANI‐Bi 2 Se 3 ) nanoplate composites are fabricated via combining in situ oxidative polymer…
Silica compounds were prepared using non-functionalized solution styrene-butadiene rubber (SSBR) to investigate effect of the functional group of silanes on the silica modification and properties of SSBR/silica compounds.
