Three dimensional (3D) spacer fabrics are constructed from two dimensional (2D) woven fabrics connected by 2D woven crosslink fabrics using thermoplastic high performance hybrid yarns. Spacer fabrics present great potential in the efficient production of fiber reinforced plastic composites with adjustable mechanical p…
We present an accurate investigation of the prototypical rare-earth cobaltite GdBaCo${}_{2}$O${}_{5.0}$ by complementary synchrotron powder and conventional source single-crystal x-ray diffraction experiments. The correct space group (Pmmm) and the accurate crystallographic structure of this compound at room temperatu…
The relationship between anomalous (re-entrant) melting and the features of the repulsive part of the intermolecular potential is studied in one-component systems with radially symmetric interactions. By making use of the Lennard-Jones-Devonshire cell model, we derive a single-phase criterion for the occurrence of a t…
A memory structure based on self-aligned silicon nanocrystals (Si NCs) grown over Al(2)O(3)-covered parallel-aligned carbon nanotubes (CNTs) by gas source molecular beam epitaxy is reported. Electrostatic force microscopy characterizations directly prove the charging and discharging of discrete NCs through the Al(2)O(…
The local structure of crystalline ${\mathrm{Ge}}_{8}{\mathrm{Sb}}_{2}{\mathrm{Te}}_{11}$ over a temperature range from 10 K to 480 K was studied. While a rhombohedral to rock-salt-like structural transition is clearly observed at 385 K via x ray (Bragg) diffraction, an x-ray absorption study shows that the local stru…
This study investigates the effects of alloying elements on the microstructural evolution of Al-rich Al–Mn–Cu–(Be) alloys during solidification, and subsequent heating and annealing. The samples were characterised using scanning electron microscopy, energy dispersive X-ray spectroscopy, synchrotron X-ray diffraction,…
The effects of addition of a series of stoichiometric salts on the nanostructuring of cationic amphiphilic peptides have been investigated through the combination of atomic force microscopy (AFM), circular dichroism (CD), and turbidity measurements. The results revealed that anions had more pronounced effects than cat…
The organic triangular-lattice 1/2-spin system EtMe${}_{3}$Sb[Pd(dmit)${}_{2}$]${}_{2}$ does not undergo classical antiferromagnetic ordering and is a strong candidate for a quantum spin liquid. It is currently an open issue whether or not the ground state of this system has a broken-symmetry and/or topological struct…
A numerical procedure to carry out the integral on the powder diffraction sphere in reciprocal space and obtain accurate powder diffraction peak profiles for small crystallites is presented. In doing so, the literature surrounding the effect of crystallite size and shape on the powder peak profile is briefly reviewed.…
To develop a force field suitable both for polyoxometalates (POMs) and organic cations, the Merck molecular force field 94x (MMFF94x) has been selected to describe the counterions used in POMs synthesis and has been combined with our force field optimized for type-II POMs with electrostatic and Van der Waals interacti…
Abstract We reveal a route for the preparation of phosphinated bisphenol, 1,1‐bis(4‐hydroxyphenyl)‐1‐(6‐oxido‐6H‐dibenz <c,e> <1,2> oxaphosphorin‐6‐yl)ethane (2) , via a one‐pot reaction of 1,1,1‐tris(4‐hydroxyphenyl)ethane and 9,10‐dihydro‐9‐oxa‐10‐phosphaphenanthrene 10‐oxide (DOPO) in the catalysis of p…
The local structure of mechanically alloyed Mg 50 Co 50 and its deuteride, Mg 50 Co 50 D 75, was investigated using the atomic pair distribution function (PDF) analysis of neutron and synchrotron X-ray total scattering data. The purpose of our study was to obtain the structural information of these amorphous alloys an…
Self-assembly and microstructural control of a hexa-peri-hexabenzocoronene–perylene diimide dyad are systematically studied by employing solvent vapor diffusion as a novel processing method. The influence of a variety of processing parameters on the microstructure and molecular organization at the surface is investiga…
We observe time-resolved and polarization dependent two-, three-, and four-photon transitions from a Ni(111) surface covered with a monolayer of hexagonal boron nitride. The spectra show features due to transitions involving two unoccupied intermediate states: the $n=1$ image potential state of Ni(111) and a boron nit…
Abstract A one‐pot modified Turkevich synthesis was used to synthesise a range of colloids from pure Ag, through Ag/Au core‐shell mixtures to pure Au by the thermal co‐addition of trisodium citrate to auric acid and silver nitrate mixtures. The colloids were analysed by means of XRD and wide‐beam energy dispersive X‐r…
The aim of this research was to study the mechanical and thermal properties of composites based on polylactic acid (PLA) and two types of reinforcements (spent kraft fibers and sisal fibers, with or without modification by silanes). Two different silane coupling agents (3-aminopropyltriethoxysilane and 3-(trimethoxysi…
A model polymorphic co-crystallization process for caffeine-glutaric acid from acetonitrile was monitored and controlled using attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR) and particle vision measurement (PVM). A new method to calculate supersaturation for co-crystallization systems…
The crossed lamellar microstructure is the most commonly formed shell structure in mollusks. Although the mechanical properties and the architecture of the crossed lamellar microstructure have been extensively studied, its formation mechanisms are largely unknown. In this study, we obtained information on the formatio…
Active compounds with antidiabetic potential were isolated from silk peptide E5K6 by consecutive ultrafiltration and gel filtration using Biogel P-2 and RS-HPLC using a YMC-Pack Pro C18 column. The highest α-glucosidase inhibitory activity of silk peptide E5K6 resulted from fractions with MW <1 kDa. The activities of…
Abstract The silica/polypyrrole core‐shell composites were fabricated by in situ chemical polymerization of pyrrole monomer on the surface of the silica spheres. Silica sol particles with narrow size distributions were prepared by hydrolysis of tetraethoxysilane with sol–gel method. Polypyrrole shell was obtained by c…
