The synchrotron based scanning transmission soft X-ray microscopy (STXM) utilizing near edge X-ray absorption fine structure (NEXAFS) is a novel technique for characterization of membrane electrode assembly (MEA) components in proton exchange membrane fuel cells (PEMFC). Component maps for carbon support, Pt and ionom…
Dewetting, i.e., the retraction of a fluid from a surface it “dislikes”, is a macroscopic phenomenon controlled through parameters like viscosity and surface tension on length-scales much larger than the size of the molecules. So far, dewetting was known to proceed in the same manner, independent of the dewetting film…
Abstract Benthic algae including benthic diatoms are one of the most vital primary producers in riverine ecosystems, and their spatial distribution and assemblage structure respond sensitively to various environmental variables. Thus, benthic diatoms have been widely used as indicators of water quality in riverine sys…
Glycan-bound nanoprobes have been demonstrated as suitable sensing probes for bacteria containing glycan binding sites. In this study, we demonstrated a facile approach for generating glycan-bound gold nanoclusters (AuNCs). The generated AuNCs were used as sensing probes for corresponding target bacteria. Mannose-capp…
Barium hollandites, a family of framework titanates that can potentially be used for the immobilization of short‐lived fission products (especially 137 Cs ) in radioactive wastes, have been investigated by high‐temperature oxide melt solution calorimetry using 2 PbO · B 2 O 3 solvent at 702°C. The enthalpies of format…
Using the conventional high temperature solid‐state reaction method Ba 2 Ca ( PO 4 ) 2 : Eu 2+ phosphors were prepared. The phase structure, photoluminescence ( PL ) properties, and the PL thermal stability of the samples were investigated, respectively. Under the excitation at 365 nm, the phosphor exhibited an asymme…
Silver nanoparticle (AgNP) film is a kind of useful material in biochemical and biomedical fields as it can be used as a sensor based on its surface plasmon resonance for surface enhanced Raman scattering (SERS) analysis. In this work, a uniform AgNP film with controlled nanoparticle size, shape, and density have been…
Ion channeling contrast (iCC) and electron channeling contrast (eCC) are caused by variation in signal resulting from changes in the angle of the incident beam and the crystal lattice with respect to the target. iCC is directly influenced by the incident ion range in crystalline materials. The ion range is larger for…
Nowadays, the electron density is recognized as a fundamental property that contains most of the information concerning the electronic structure of molecules, and, therefore, its determination from high-resolution X-ray diffraction data is becoming more and more important. In this context, we propose a new strategy fo…
The filling behavior of Mg atoms into CoSb3 lattice voids under pressure was investigated theoretically, revealing ambient-pressure-inaccessible Mg-filled CoSb3 can be stabilized under high pressure. Inspired by this result, we synthesized Mg-filled CoSb3 using high pressure synthesis. The synthetic samples show Im3¯…
Group-IVa elements silicon and germanium are known for their semiconducting properties at room temperature, which are technologically critical. Metallicity and superconductivity are found at higher pressures only, Ge β-tin (tI4) being the first high-pressure metallic phase in the phase diagram. However, recent experim…
A review of studies is presented in the evaluation of fabric tactile properties with a focus on knitted fabrics and developments since the mid-1990s in particular. The fundamental differences in structure between woven and knitted fabrics are highlighted with their consequent different fabric tactile properties. Consi…
Herein, we report the synthesis, microstructure, and magnetic properties of cadmium ferrite (CdFe2O4) thin films with both an ordered cubic network of 18 nm diameter pores and single-phase spinel grains averaging 13 nm in diameter. These mesoporous materials were produced through facile polymer templating of hydrated…
Nanoparticles are the preparations having size in nanometers. Particulate systems like nanoparticles have been used as a physical approach to alter and improve the pharmacokinetic and pharmacodymanic properties of various types of drug molecules.They have been used in vivo to protect the drug entity in the systemic c…
We show that the optical properties of a particle above a plane dielectric interface differ dramatically from those of the same particle embedded in a homogeneous matrix. Calculations for gold and silver spheres have been carried out in using the exact multipole expansion method, providing thus benchmark results for t…
We investigate the optical and morphological effects of silver island films exposed to atmosphere. Silver nanoparticles with an average radius below 5 nm were highly tarnished after one week, showing significant morphological changes. Using x-ray photoelectron spectroscopy we demonstrate that the tarnishing is predomi…
Electronic characteristics of a single-walled carbon nanotube (SWCNT) strongly depend on minor variations in its atomic arrangement, specifically chirality. Therefore, precise control over nanotube chirality is highly desired for their application. Theoretically, SWCNTs with different structures have different chemica…
Structural, elastic, optical, thermodynamical, and electronic properties of yttrium oxide compound in cubic phase have been studied using the full‐potential augmented plane waves ( FP ‐ LAPW ) within density functional theory ( DFT ) framework. Four different approximations were used for exchange‐correlation potential…
The diffusion and reaction are two general kinetic factors playing an important role in the structure development of materials. Upon diffusion limitation, a noncompact structure is easily formed, while a compact structure is usually formed in a reaction-limited condition. In this Article, we take the precipitation of…
Abstract This study proposes a way to control the wettability of zinc oxide nanowires (NWs) by properly selecting the kind of seed layer used to promote the growth of the wires. ZnO seed layers were synthesized on silicon and conductive substrates by a physical vapor deposition approach and a wet‐chemical route, namel…
