In this paper, micro (mean size is 1 μm) and nano (mean size is 10 nm) TiO2(Titania) were loaded into epoxy resin at the same time. Eleven kinds of samples with different filler contents were prepared. Flashover characteristics of the epoxy composites were investigated under 50 ns (rise time)/1.5 μs (half-height width…
We explore the intrinsic viscosity of 40 nm silica particles in concentrated solutions of low molecular weight hydroxyl terminated polyethylene glycol (PEG), polyethylene glycol dimethyl ether (PEGDME) and polytetrahydrofuran (PTHF). Our goal is to develop a correlation between the intrinsic viscosity and the strength…
Xylene is an aromatic hydrocarbon with a single ring and two methyl groups attached to this ring in positions 1-2, 1-3 and 1-4, called o-xylene, m-xylene, and p-xylene, respectively. Because of the similarities in their physicochemical properties, it is very difficult to obtain these isomers in a pure form. For this r…
Polyelectrolyte "complexes" have been studied for almost a century and find more and more applications in cosmetics and DNA transfection. Most of the available studies focused on the thermodynamic aspects of the "complex" formation, mainly to determine phase diagrams and the influence of diverse physicochemical aspect…
A portable, low-cost optical immunosensor has been developed using environment-friendly gold nanoclusters (AuNCs) as signal amplification labels. The stable and robust film, poly(dopamine), was used to immobilize biomolecules on an indium tin oxide chip for the construction of biosensor, as confirmed by scanning elect…
Nano-composites of LiNH(2)-LiH-xMg(BH(4))(2) (0 ≤ x ≤ 2) were prepared by plasma metal reaction followed by a nucleation growth method. Highly reactive LiNH(2)-LiH hollow nanoparticles offered a favorable nucleus during a precipitation process of liquid Mg(BH(4))(2)·OEt(2). The electron microscopy results suggested th…
Abstract A series of plasma‐mediated thin films (≈175 nm), containing silver nanoparticles embedded in an organosilicon matrix with controllable properties (silver content, nanoparticle size, matrix composition), were deposited onto stainless steel and chemically and structurally characterized, using a large set of an…
Quantum dots (QDs) have been utilized as light harvesting assemblies on photoanodes for applications in quantum dot sensitized solar cells. QDs are bound (sensitized) to a titanium dioxide surface using the bifunctional linker molecule 3-mercaptopropionic acid. The cadmium selenide QDs are synthesized following a trio…
The structural evolution of Pb(Mg(1/3)Nb(2/3))O(3) (PMN) has been reviewed in terms of characteristic temperatures, length scales and timescales, with a view to considering the overall relaxor behaviour from the perspectives of strain and elasticity. A conventional analysis of lattice parameter data in terms of sponta…
In order to propel the development of metal magnetic memory (MMM) technique in fatigue damage detection, a modified Jiles–Atherton (J–A) model is constructed to describe MMM mechanism in elastic stress stage. The MMM phenomenon is discussed from the view of energy minimum theory and equivalent magnetic field theory, t…
Ambient-condition Raman spectra were collected in the strongly correlated NiS${}_{1\ensuremath{-}x}$Se${}_{x}$ pyrite ($0\ensuremath{\le}x\ensuremath{\le}1.2$). Two samples ($x=0$ and $x=0.55$) were studied as a function of pressure up to 10 GPa, and for the $x=0.55$ sample the pressure dependence of the infrared refl…
Ligand denticity profoundly affects the ability of organic ligands to control crystal shape during aqueous crystallization of zinc oxide. A method is presented for rapidly screening the shape-control activity of organic molecules during zinc oxide crystallization. This method involves the solution-phase growth and iso…
The equilibrium structure and ordering kinetics of random AB block copolymers is investigated using a Lennard-Jones bead–spring model and a soft, coarse-grained model. Upon increasing the incompatibility a disordered microemulsion-like structure is formed, whose length scale slightly increases with segregation. The st…
We present the results of our Monte Carlo simulation of the Ising-O(3) model on two-dimensional (2D) and quasi-2D lattices. This model is an effective classical model for the stacked square-lattice ${J}_{1}$-${J}_{2}$ Heisenberg model, where the nearest-neighbor (${J}_{1}$) and next-nearest-neighbor (${J}_{2}$) coupli…
Cistanche deserticola MA (C. deserticola) has been widely used as a laxative herbal in herbal medicine for the treatment of irritable bowel syndrome or constipation, and echinacoside (ECH) is one of the major bioactive ingredients in this herbal. Our aim was to investigate the effect of ECH on intestinal epithelial ce…
Elastic and anelastic behaviour of single crystal and ceramic samples of Pb(Mg(1/3)Nb(2/3))O(3) has been investigated at frequencies of ~0.1-1.2 MHz through the temperature interval 10-800 K by resonant ultrasound spectroscopy (RUS). Comparison with data from the literature shows that softening of the shear modulus be…
This study used sodium borohydride to reduce graphene oxide to graphene nanosheets (GNS), which contain the carboxylic functional group that becomes carboxyl (–COOH) or carboxylate anion (–COO−)-type in the acid or alkaline environment, respectively. The GNS with didodecyldimethylammonium bromide (DDAB) particles beco…
A 50 : 50 wt% mixture of L-lactide and trimethylene carbonate yields a eutectic at 21.3 °C. This mixture was exploited to prepare poly(L-lactide) homopolymers at r.t. without addition of extra solvent. The intrinsic kinetic behavior of the DBU organocatalyst also allowed for the sequential polymerization of both comon…
Abstract Different micromechanical models for the prediction of mechanical properties of CNT/polymer composites, taking into consideration filler percolation throughout the matrix, are considered. It is demonstrated that the critical filler volume fraction, where a percolating network of CNTs is forming, marks a “turn…
The incorporation of poly(ethylene glycol) (PEG) chains at the focal point of dendrimers results in customizable platforms where the careful selection of the PEG length, the nature of the peripheral groups, and the structure and generation of the dendritic block entail materials for specific applications in the biomed…
