Abstract New members of the Ln[Au(CN)2]3·3H2O and [nBu4N]2[Ln(NO3)4Au(CN)2] series Ln = Ce (CeAu3 and CeAu respectively) are reported herein where their synthesis, structure and photoluminescence properties are discussed. The first is a 3‐D coordination polymer with aurophilic interactions of 3.35 Å and the latter is…
The aim of this work is to evaluate the effect of sonication and clay content on the crosslinking and curing characteristics and the final properties of unsaturated polyester/montmorillonite nanocomposites. The Cloisite 30B clay (1, 3 or 5 wt.%) was dispersed in the resin by mechanical stirring and sonication at diffe…
INTRODUCTION The three important parameters on which the selection of the most suitable drug delivery system is based are the drug, the disease state, and the latter’s location in the body. Currently, small-molecule drugs continue to dominate the pharmaceutical market despite biotech drugs making a distinct niche for…
The two-dimensional (2D) or three-dimensional (3D) multiway power dividers based on transformation optical theory are proposed in this paper. It comprises of several nonisotropic mediums and one isotropic medium without any lumped and distributed elements. By using finite embedded coordinate transformations, the incid…
Polyamide comprises one of the major classes of polymers. Layered silicates (nanofiller) may enhance properties of polyamide-based hybrids even at very low content. Aliphatic polyamides (nylons) have often been chosen for commercial applications because of excellent physical and chemical properties. Aromatic polyamide…
Carbons are the main electrode materials used in electrochemical capacitors, which are electrochemical energy storage devices with high power densities and long cycling lifetimes. However, increasing their energy density will improve their potential for commercial implementation. In this regard, the use of high surfac…
A molded film of single-component polymer-grafted nanoparticles (SPNP), consisting of a spherical silica core and densely grafted polymer chains bearing hydrogen-bonding side groups capable of physical crosslinking, was investigated by in situ ultra-small-angle X-ray scattering (USAXS) measurement during a uniaxial st…
Abstract The nature of the bound water in solids with hydrogen‐bonded networks depends not only on temperature and pressure but also on the nature of the constituents. The collapse and reorientation of these network structures determines the stability of hydrated solids and transitions to other crystalline or amorphou…
Abstract An advanced technique for bulk protein crystallization based on solvent evaporation is introduced. Hen egg white lysozyme is crystallized from its buffered aqueous solution in a stirred tank at low pressure and, thus, moderate boiling temperatures. No crystallizing agent to reduce the solubility is needed for…
ABSTRACT Polyurethane adhesives are found in a variety of applications. To ensure durability and functionality, a polyurethane adhesive is required to possess good adhesive properties and thermal stability. In this study, polyurethane adhesives were fabricated using isocyanate and polyols of various type and functiona…
Hydrogen transport in the outer Al 2 O 3 scale is the rate-limiting step for H-permeation resistance of FeAl/Al 2 O 3 -type aluminide tritium permeation barriers (TPBs) in fusion reactors. With first-principle calculations, the effects of Cr, a main impurity element in the Al 2 O 3 scale, on intrinsic point defect for…
Herein, we reported a facile method to prepared uniform yolk like nanocomposites with well-defined N-doped carbon shell (C), in which the cores@SiO2@polydopamine (Pdop) were used as the sacrificed template. Typically, inherited from the functional Au core, the yolk particles presented excellent catalytic activities.
Protease activable antifouling coatings based on peptide-poly(ethylene glycol) conjugates are shown. The material-specific adsorption of a bioconjugate is temporarily suppressed by extending a titanium binding sequence with a proteolytically cleavable epitope and a suitable interfering domain. The adsorption of the PE…
The influence of high austenite stiffness of shape memory alloy (SMA) on the response of base-isolated benchmark building has been investigated. Dynamic analysis was performed by solving the governing equations of motion using Newmark-beta method under three near-fault earthquake motions. The super-elastic behavior of…
Quantifying the effect that nanofiber mat chemistry and hydrophilicity have on microorganism collection and inactivation is critical in biomedical applications. In this study, the collection and inactivation of Escherichia coli K12 was examined using cellulose nanofiber mats that were surface-functionalized using thre…
One of the first commercially available products of bacterial nanocellulose (BNC) was nata de coco. Nata de coco is a white, gelatinous and chewy material used for the production of sweets and desserts. It is produced from coconut water or coconut milk by the microorganism Acetobacter aceti subsp. xylinum through a fe…
This work presents a study of the luminescence properties of Er 3+ when included into two different TiO 2 hosts: A polycrystalline and an amorphous host. The two host environments were produced by depositing two thin films with different Er 3+ concentration using radio-frequency magnetron sputtering. Structural analys…
Copolymers of o-anthranilic acid and o-phenylenediamine/hydrophilic bentonite nanocomposites were synthesized by 1:1 molar ratios of the respective monomers with different percentages of nanoclay through modified in situ chemical copolymerization. The results obtained were justified by measuring the Fourier transform…
The atomistic mechanisms active during plastic deformation of nanocrystalline metals are still a subject of controversy. The recently developed approach of combining automated crystal orientation mapping (ACOM) and in situ straining inside a transmission electron microscope was applied to study the deformation of nano…
Preparation of SiC(0001) substrates is of high relevance to graphene growth. Yet, if only a smooth surface could be achieved, heteroepitaxy of many other two-dimensional materials comes into reach. Here we report a novel approach to hydrogen etching of SiC, based on stepwise ultrapure H exposure with slow substrate co…
