Summary The behaviour of six concretes at high temperature (600 °C) and in particular the risk of fire spalling is studied. Tests are performed with two sizes of samples: small samples (300 × 300 × 120 mm3) and small slabs (700 × 600 × 150 mm3). Different storage conditions (pre‐drying at 80 °C, air and water storing)…
A facile strategy has been developed to synthesize sliver nanoparticles (Ag NPs) decorated three-dimensional graphene (3DG) through hydrothermal process. The AgNPs-3DG composites are directly fabricated into a free standing sensing electrode for electrochemical detection of hydrogen peroxide (H2O2) in phosphate buffer…
Quercetin, a natural protective bioflavonoid, possesses diverse pharmacologic effects, such as antioxidant, anti-inflammatory, anti-proliferative, and anti-angiogenic activities. Recently, quercetin's effect in cancer prevention and treatment was recognized. However, the poor water solubility and low-bioavailability o…
A key issue in catalyst design is understanding how adsorption energies of surface intermediates vary across both different surfaces and various types of adsorbing atoms. In this work, we examine trends in adsorption energies of a wide variety of adsorbates that attach to transition metal surfaces through different at…
Since the last decade, lightening of automotive structure was mainly achieved by gauge reduction using ultrahigh strength steels such as dual phase and transformation induced plasticity grades. However, gauge reduction can significantly reduce the stiffness. Limits are today reached for some applications such as chass…
The fascinating biological activity of gold coordination compounds has led to the development of a wide range of complexes. The precise biological action of such species is often poorly understood and the ability to map gold distribution in cellular environments is key. This article discusses the recent progress in lu…
We study the temperature dependence of the spin Hall magnetoresistance (SMR) in yttrium iron garnet/platinum hybrid structures via magnetization orientation dependent magnetoresistance measurements. Our experiments show a decrease of the SMR magnitude with decreasing temperature. Using the sensitivity of the SMR to th…
Campylobacter jejuni is one of the most frequent causes of bacterial gastrointestinal food-borne infection worldwide. This species is part of the normal flora of the gastrointestinal tracts of animals used for food production, including poultry, which is regarded as the primary source of human Campylobacter infections…
This paper proposes two simple approaches for in situ generation of nickel nanoparticles in the carbon matrix of rice husk char (RHC) via incipient wetness impregnation and pyrolysis. The nickel oxides (i.e., NiO) in the RHC matrix can be preliminarily in situ reduced into metallic nickel (Ni 0 ) by carbothermal reduc…
Although magnesiothermic reduction has attracted immense attention as a facile route for the fabrication of mass‐scale Si nanostructures for high‐capacity lithium‐ion battery applications, its low conversion yield (<50%) and the discovery of a sustainable and low‐cost precursor remain challenging. Here, an unprecedent…
In order to examine the competition between hydrogen bonds and halogen bonds when confronted with a probe molecule containing multiple potential acceptor sites and one hydrogen-bond donor, five heteroaryl-2-imidazoles were synthesized and subsequently co-crystallized with fifteen different halogen-bond donors. 30 of t…
A regioselective synthesis of an azacoronene fused with two peripheral thiophene groups has been realized through a concise synthetic route. The resulting thienoazacoronene (TAC) derivatives show high degree of self-organization in solution, in single crystals, in the bulk, and in spuncast thin films. Spuncast thin fi…
Effective clinical treatments for volumetric muscle loss resulting from traumatic injury or resection of a large amount of muscle mass are not available to date. Tissue engineering may represent an alternative treatment approach. Decellularization of tissues and whole organs is a recently introduced platform technolog…
This quantum mechanical study was performed to assess the accuracy of level of theory for the prediction of UV/Visible spectra of aminoazobenzene dyes. Four solvation models (PCM, I-PCM, SCI-PCM and IEF-PCM) and four functionals (CAM-B3LYP, LC-BLYP, BHandHLYP and PBE0) were tested. Double and triple zeta basis sets wi…
We measured the electro-optic (EO) coefficients (r33) of thin-film devices made from several monolithic, high number density organic EO chromophores with and without additional charge barrier layers. We found that a cross-linkable benzocyclobutene layer was very effective in suppressing unwanted, leakage current, keep…
The possibility of the new class ferroelectric materials of wurtzite structure simple chalcogenide was discussed using modern first-principles calculation technique. Ferroelectricity in the wurtzite structure (P63mc) can be understood by structure distortion from centrosymmetric P63/mmc by relative displacement of cat…
Designing thermoelectric materials with high figure of merit ZT = S(2)GT/Ktot requires fulfilling three often irreconcilable conditions, that is, the high electrical conductance G, small thermal conductance Ktot, and high Seebeck coefficient S. Nanostructuring is one of the promising ways to achieve this goal as it ca…
Modern high-throughput screening (HTS) is a well-established approach for hit finding in drug discovery that is routinely employed in the pharmaceutical industry to screen more than a million compounds within a few weeks. However, as the industry shifts to more disease-relevant but more complex phenotypic screens, the…
In this Letter, we describe an accurate antibody detection method using a fabricated extended-gate type organic field-effect-transistor (OFET), which can be operated at below 3 V. The protein-sensing portion of the designed device is the gate electrode functionalized with streptavidin. Streptavidin possesses high mole…
During operation wind turbine blades are exposed to a wide variety of atmospheric and environmental conditions; inspection reports for blades that have been operating for several years show varying degrees of leading edge erosion. It is important to be able to estimate the impact of different stages of erosion on wind…
