The present paper describes an innovative method of producing silver nanoparticles incorporated into an aluminium nano‐oxide substrate. The method utilises thermal decomposition and reduction, which yields an Al2O3–Ag nanopowder with the average size of particles ranging from 43 to 60 nm and the average size of agglom…
A series of degradable polymer networks containing poly(ω-pentadecalactone) (PPD) switching segments showing a thermally-induced shape-memory effect were synthesized by co-condensation of PPD-macrotriols or -tetrols with an aliphatic diisocyanate. Thermal and mechanical properties at different temperatures were explor…
This study investigated the mechanical properties of thermoplastic natural rubber (TPNR) nanocomposites reinforced by multi-walled carbon nanotubes (MWNTs). The TPNR nanocomposites were prepared using melt blending method from polypropylene, natural rubber, and liquid natural rubber as a compatibilizer, respectively,…
Nanodiamond has recently attracted great attention for its intrinsic luminescence in the visible range which can be used as a tracking marker in many biological applications. In this work, photoluminescence (PL) of nanodiamonds interacting with biological macromolecules, such as proteins lysozyme and albumin, is studi…
Due to its suitable physical properties and good biocompatibility, the titanium (Ti) can be used for development of porous structures for biomedical applications. The state of art in the field of corrosion resistance showed problems with corrosion analysis of porous metals. Therefore, it is essential to understand the…
Abstract This investigation was undertaken to prepare composites of waste polyethylene (WPE) with concentrations of 5, 15, and 25 wt% of waste rubber powder (WRP) and to determine the changes in properties of these composites before and after treatment of the WRP with acrylic acid. Mechanical, physical, thermal, FTIR,…
Hot engine exhaust represents a resource that is often rejected to the environment without further utilization. This resource is most prevalent in the transportation sector, but stationary engine—generator systems also typically do not utilize this resource. Engine exhaust is considered high-grade heat and can potenti…
We demonstrate a significant control of the polarization response under an applied magnetic field for a magnetoelectric (ME) heterostructure. This structure was comprised of a 2 μm thick ferroelectric BaTiO3 (BTO) film deposited on flexible ferromagnetic metallic glass foil (25 μm thick). Au was used as a buffer layer…
The self-consistent field theory (SCFT) complemented with the Poisson-Boltzmann equation is employed to explore self-assembly of polyelectrolyte copolymers composed of charged blocks A and neutral blocks B. We have extended SCFT to dissociating triblock copolymers and demonstrated our approach on three characteristic…
Abstract In this paper, two silicon‐containing cycloaliphatic olefins were synthesized through the nucleophilic substitution reactions of cyclohex‐3‐enyl‐1‐methanol with di‐ or tri‐chlorosilane compounds. Then, after epoxidation, two new cycloaliphatic epoxy resins with different epoxy groups were successfully prepare…
Texaphyrins, a class of tumor selective expanded porphyrins capable of coordinating large metals, have been found to act as redox mediators within biological systems. This review summarizes studies involving their experimentaluse in cancer chemotherapy. Mechanistic insights involving their presumed mode of action are…
The intense 1.32, 1.73, and 2.67 μm near-infrared and midinfrared emissions were observed from the Dy3+-doped GeSe2–Ga2Se3–MI (M=K, Cs, Ag) chalcohalide glasses. These glasses are red light transparent therefore can be pumped by a semiconductor lasers operating at ∼808 nm. The 2.67 μm emission has not been reported ye…
Structural disorder of ZnO nanopowders with mean crystallite size down to 15 nm, produced by mechanical activation in high energy mills, has been analyzed by x-ray diffraction and Raman spectroscopy. The influence of such disorder on optical and electronic properties of activated ZnO nanopowders has been investigated…
Abstract As a family of functional inorganic clusters, polyoxometalates (POMs) were introduced into hybrid self‐assemblies with the assistance of the supramolecular interaction with diverse organic cationic molecules, which reinforced both the processibility and functionality of the POMs. This method not only improved…
We report a theoretical investigation of free-standing Fe(x)Co(y)Ni(z) ternary clusters with x + y + z = 5 and 6. Our study is performed within density functional theory as implemented in the GAUSSIAN 03 set of programs and with the BPW91/SDD level of theory. We analyze the geometries, chemical order, local and total…
Borrowing ideas from tight binding model, we propose a board class of lattice field models that are classified by non simply laced Lie algebras. In the case of AN − 1 ≃ su(N) series, we show that the couplings between the quantum states living at the first nearest neighbor sites of the lattice \documentclass[12pt]{min…
Under some conditions, charges may transport like an isolated packet in polyethylene. It has been demonstrated that many factors, such as applied field strength, temperature, and material itself, influence on formation and migration of space charge packet, which cause many difficulties in understanding the general mec…
The corrosion inhibition of thiadiazole derivatives for brass in natural seawater has been evaluated by potentiodynamic polarisation and electrochemical impedance spectroscopic techniques. It was found that the inhibition efficiency of the thiadiazole derivatives, namely, 2-amino-5-ethyl-1,3,4- thiadiazole(AETD), 2-am…
Abstract Organic–inorganic hybrids based on polyoxometalate scaffolds(POMs) are a unique class of molecular metal‐oxides featuring a composite surface, whereby the merging of complementary domains stimulates new functions and enhances performances. The interaction between the organic and inorganic components can be de…
Thermal dissipation in molecular electronic devices is a critical issue for the proper functioning of such devices. In this work, molecular dynamics (MD) simulations were carried out to study the thermal energy transport in GaAs-SAM (self-assembly monolayer)-GaAs junctions, with alkanedithiols being the SAM molecules.…
