The grain refinement and mechanical properties of a Cu–0.1Cr–0.06Zr alloy subjected to equal channel angular pressing (ECAP) at a temperature of 673 K were examined. The microstructure evolution was characterised by the development of a large number of low-angle subboundaries at small strains. An increase in the true…
The effect of cross-link density on the reversible shape-memory effect (SME) under constant load was systematically studied in cross-linked linear poly(ε-caprolactone) (PCL). A remarkable reversible SME under stress-free conditions was observed in PCL with the highest achieved cross-link density. Thermal properties as…
Assisted with polyethylenimine, 4.0 L of water-soluble AgInS 2 quantum dots (AIS QDs) were successfully synthesized in an electric pressure cooker. As-prepared QDs exhibit yellow emission with a photoluminescence (PL) quantum yield up to 32%. The QDs also show excellent water/buffer stability. The highly luminescent A…
Abstract The recently discovered two-dimensional (2D) semimetal 1 T´-MoTe 2 exhibits colossal magnetoresistance and superconductivity, driving a strong research interest in the material’s quantum phenomena. Unlike the typical hexagonal structure found in many 2D materials, the 1 T´-MoTe 2 lattice has strong in-plane a…
In spite of the still increasing number of engineered nanomaterial (ENM) applications, large knowledge gaps exist with respect to their environmental fate, especially after release into air. This review aims to summarize the current knowledge of emissions and behavior of airborne engineered nanomaterials. The whole EN…
Purpose The ability to evaluate pathological changes in the spinal cord in multiple sclerosis (MS) is limited because T 1 ‐ and T 2 ‐w MRI imaging are not sensitive to biochemical changes in vivo. Amide proton transfer (APT) chemical exchange saturation transfer (CEST) can indirectly detect amide protons associated wi…
Abstract Maghemite (γ-Fe2O3) with a spinel structure, consisting of tetrahedral Fe3+ (Fe3+Td) and octahedral Fe3+ (Fe3+Oh) sites, has been intensively investigated as an environmentally benign catalyst for selective catalytic reduction (SCR) of NOx with NH3. In most cases, Fe3+Oh sites were regarded as catalytically a…
Abstract A family of halogen‐substituted Schiff base iron(II) complexes, [Fe II (qsal‐X) 2 ], (qsal‐X=5‐X‐ N ‐(8‐quinolyl)salicylaldimines)) in which X=F ( 1 ), Cl ( 2 ), Br ( 3 ) or I ( 4 ) has been investigated in detail. Compound 1 shows a temperature invariant high spin state, whereas the others all show abrupt sp…
at gigahertz frequencies is drastically higher than that at dc, whereas the effect is absent on surfaces with in-plane polarized domains. First-principles and model calculations indicate that the frequency range and selection rules are consistent with the periodic sliding of the DW around its equilibrium position. Thi…
This report describes the synthesis of metallic silver nanoparticles (AgNPs) using extracts of four medicinal plants ( Aegle marmelos ( A. marmelos ), Alstonia scholaris ( A. scholaris ), Andrographis paniculata ( A. paniculata ) and Centella asiatica ( C. asiatica )). The bio-conjugates were characterized by UV–visib…
Abstract Selective doping of Ni 2+ in octahedral sites provided by nanocrystals embedded in glass-ceramics (GCs) is crucial to the enhancement of broadband near-infrared (NIR) emission. In this work, a NIR emission with a full-width-at-half-maximum (FWHM) of 288 nm is first reported from ZnGa 2 O 4 : Ni 2+ nano-spinel…
In this paper, pure and rare earth (Cerium) doped ZnO nanoparticles were synthesized via simple wet-chemical technique at low temperature. The structural analyses were carried out by Powder X-ray diffraction (PXRD) and it is reveal that the synthesized nanoparticles were well-crystalline and possessing hexagonal wurtz…
This work investigated the effect of maleic anhydride (MA)-modified poly(lactic acid) (PLA), which is melt-blended with different untreated and aqueous borax (BR)-treated hybrid oil palm empty fruit bunch fibers (EFBF)/Kenaf core fibers (KCF), and compression-molded into corresponding hybrid biocomposites. These hybri…
Inspired by marine mussel adhesive proteins, polymers with catechol side groups have been extensively explored in industrial and academic research. Here, Pluronic L-31 alcoholate ions were used as the initiator to prepare a series of polypeptide-Pluronic-polypeptide triblock copolymers via ring-opening polymerization…
Implantable sensor devices require coatings that efficiently interface with the tissue environment to mediate biochemical analysis. In this regard, bioinspired polymer hydrogels offer an attractive and abundant source of coating materials. However, upon implantation these materials generally elicit inflammation and th…
The roughness of woven fabrics strongly limits print quality, which is particularly critical in printing of conductive circuits on fabrics. This work demonstrates the use of wood-derived cellulose nanofibrils (CNFs) mixed with a plasticizer as coatings of woven cotton fabrics for inkjet printing using (i) conventional…
The potential environmental impact of nanomaterials is a critical concern and the ability to assess these potential impacts is top priority for the progress of sustainable nanotechnology. Risk assessment tools are needed to enable decision makers to rapidly assess the potential risks that may be imposed by engineered…
Viscoelastic properties of battery electrodes in contact with electrolyte solutions may affect the electrodes’ cycling performance. However, they are not easily assessed by in situ measurements. Herein, we show that an electrochemical quartz-crystal microbalance with dissipation (EQCM-D) enables extraordinary sensitiv…
The fluorescence properties of the BODIPY dye and its two meso-substituted derivatives, tert-butyl- and phenyl-BODIPY, are rationalized. The non-emissive behavior of the latter two are attributed to the energetically accessible low-lying conical intersection between the ground state and the lowest excited singlet stat…
Serial (femtosecond) crystallography at synchrotron and X-ray free-electron laser (XFEL) sources distributes the absorbed radiation dose over all crystals used for data collection and therefore allows measurement of radiation damage prone systems, including the use of microcrystals for room-temperature measurements. S…
