The charge density mismatch (CDM) approach has been a strategy to apply multiple templates in the zeolite synthesis. In the synthesis of the UZM-4 zeolite, tetraethylammonium (TEA) aluminosilicate solution is used as CDM solution although the TEA cation is not incorporated in the final product. We focused on the aging…
Carbon-proton dipole-dipole couplings between bonded atoms represent a popular probe of molecular dynamics in soft materials or biomolecules. Their site-resolved determination, for example, by using the popular DIPSHIFT experiment, can be challenged by spectral overlap with nonbonded carbon atoms. The problem can be s…
Density functional theory was used to investigate the electronic and charge-transport properties of the trinuclear gold Au 3 (CH 3 N═COCH 3 ) 3 crystal. Hole transport is found to be anisotropic and characterized by a very small effective mass of about 0.21 m 0 along the stacking direction of the Au 3 molecules. Inter…
Shear deformation analysis and diffusion behavior of Copper-Zirconium Bulk Metallic Glasses (BMG) is studied for different combinations of processing parameters. Melt holding temperature, melt holding duration, cooling rate of melt and composition of BMG are varied to obtain BMGs of different structures. The as-quench…
Theophylline is the most useful bronchodilators for the treatment of severe reversible bronchospasm. The fluctuations of serum theophylline level in clinical practice and associated central nervous system side effects necessitate the development of an extended release formulation. In the present study, theophylline-lo…
Solution and solid state studies on Cu(II) complexes of pyridine-2-hydroxamic acid (HPicHA) and pyridine-2,6-dihydroxamic acid (H2PyDHA) were carried out. The use of methanol/water solvent allowed us to investigate the Cu(II)-HPicHA equilibria under homogeneous conditions between pH 1 and 11. In agreement with ESI-MS…
Irradiation inside some transparent materials such as fused silica can induce nanograting structures at the focal area. Here, we investigate experimentally how the nanograting formation can be influenced by tuning the ionization property of the transparent material, which is achieved by irradiation inside a porous gla…
The runnability and convertibility of biopolymer dispersion–coated paperboard were determined using a novel adjustable packaging line equipped with a tray-pressing mould. Commercial paperboard was dispersion barrier coated on the back-side using a dual polymer system containing both a synthetic and a renewable biopoly…
An analytical closed form diffusive model is developed of Joule heating in a device consisting of a nanowire connected to two contacts on a substrate. This analytical model is compared to finite-element simulations and demonstrates excellent agreement over a wider range of system parameters in comparison to other rece…
Following our previous report of five anhydrous lithium tartrates 1 – 5 (tart = C 4 H 4 O 6 2– ), we have synthesized and solved the single crystal structures of four new I 1 O 2 inorganic–organic frameworks, all with the same chemical formula, Li 2 (tart). Reactions between lithium acetate and the meso, chiral, and r…
The solid-state organization of a benzothiadiazole-cyclopentadithiophene copolymer with long, branched decyl-tetradecyl side chains (CDT-BTZ-C14,10) is investigated. The C14,10 substituents are sterically demanding and increase the π-stacking distance to 0.40 nm from 0.37 nm for the same polymer with linear hexadecyls…
The use of bio-binder as a replacement to petroleum-based asphalt binders has received considerable attention in recent years. The objective of this study was to conduct a comprehensive laboratory evaluation of asphalt mixtures containing bio-binder technology at a content of 20, 25.5, 30, and 50%. To achieve this obj…
Spin is the thing: Iron–sulfur proteins of the rubredoxin family only have one Fe center coordinated by four cysteine residues (see picture, Fe orange). A multiscale modeling approach is used to see if FeS bond dissociation in these iron–sulfur clusters occurs by heterolytic fission or homolytic cleavage. As Fe compl…
Fast magnetization precession was observed in L10-FePt thin films with different L10 order parameter values by all optical pump–probe technique. Precession frequency was varied widely for the films with different order parameter, which is due to large difference in perpendicular magnetic anisotropy. Gilbert damping co…
In ITER, mirrors will be used as plasma-viewing elements in all optical and laser diagnostics. In the harsh environment, mirror performance will degrade hampering the operation of associated diagnostics. The most adverse effect on mirror performance is caused by the deposition of impurities. It is expected that the mo…
Platinum coated by silver nanoparticles was synthesized, which displays a unique structure where polycrystalline platinum particles are completely encapsulated in continuous monocrystalline silver shells. These particles display accentuated electronic properties, where the silver shells gain electron density from the…
The feasibility of using alternative fuels in an effort to support sustainability in the transportation sector is explored in this book. Potential avenues for using various alternative fuels are assessed, as well as their effect on the environment, such as global warming and climate change. Experimental investigations…
New organic–inorganic fluorescent probes made by attaching the tripodal polyamine (tris(2-aminoethyl))amine ( tren ), propylamine, or diethylenetriamine functionalized with pyrene as a fluorophore to an γ-aluminum oxohydroxide matrix have been prepared and studied both in solution and supported on the surface of boehm…
${\mathrm{YbRh}}_{2}{\mathrm{Si}}_{2}$ is a prototypical system for studying unconventional antiferromagnetic quantum criticality. However, ferromagnetic correlations are present which can be enhanced via isoelectronic cobalt substitution for rhodium in $\mathrm{Yb}({\mathrm{Rh}}_{1\ensuremath{-}x}{\mathrm{Co}}_{x}{)}…
As alternative hydrophobic adsorbent for DNA adsorption, supermacroporous cryogel disks were synthesized via free radical polymerization. In this study, we have prepared two kinds of cryogel disks: (i) poly(2-hydroxyethyl methacrylate-N-methacryloyl-l-tryptophan) [p(HEMA-MATrp)] cryogel containing specific hydrophobic…
