The interplay of thermodynamic forces and self-generated stresses induced in different compositions, and at different quench depths on the phase behavior of dynamically asymmetric PS/PVME blends are studied. The thermodynamic phase diagram is obtained from dynamic temperature sweep experiments. Phase contrast optical…
An alloy of cast iron and copper (Fe-Cu) has been developed using a stir cast process. The compositional, microstructural characterization and wear property of the developed Fe-Cu alloy were carried out with the aids of X-ray diffractometer, scanning electron microscope (SEM) and pin on Disc machine. The mechanical pr…
The investigated material is a quenched&tempered steel for hydrogen applications. Understanding of hydrogen embrittlement and its effect on the mechanical characteristics of steel becomes fundamental. It is, in fact, well known that the atomic hydrogen can cause embrittlement and degradation of the mechanical characte…
A simple core/shell ZnS:Cu/ZnS QD based fluorescence enhancement system is constructed for detecting uric acid. The method with high sensitivity, selectivity and lower toxicity features was applied for determination of UA in real samples.
We present a new optimization-based method for atomistic-to-continuum (AtC) coupling. The main idea is to cast the latter as a constrained optimization problem with virtual Dirichlet controls on the interfaces between the atomistic and continuum subdomains. The optimization objective is to minimize the error between t…
A new type of monodisperse mesoporous titania microspheres possessing visible (Eu3+, Sm3+) and near-infrared (Sm3+, Yb3+, Nd3+) luminescence were synthesized with covalent linking to Ln(dbm)3bpdc complexes (Ln = Eu, Sm, Yb, Nd, dbm = dibenzoylmethanate, bpdc = 2,2′-bipyridine-4,4′-dicarboxylic acid). These lanthanide…
In vivo simultaneous and multisite tumor rapid-targeting through specifically biosynthesized gold nanoclusters could be readily followed and monitored by real-time fluorescence imaging.
In this study, corrosion behavior and mechanical properties of AISI 304 austenitic stainless steel, which was borided with Nanoboron powder, was investigated. The commercially available steel was subjected to a boriding treatment with a size of 10–50 nm Nanoboron powders, at the temperatures of 1223 K to 1273 K with b…
Well–defined and nearly monodisperse one–dimensional (1D) Er3+:Gd2O3 were successfully synthesized through co– precipitation technique followed by a subsequent heat treatment process, without using any kind of organic capping regent, fuel, surfactant, membrane, template or catalyst. Ammonium hydroxide alkali solution…
Evaluating the capability of electrospinning method as an efficient versatile approach for fabrication of fibers, a central composite design (CCD) model was used to design an experimental program for investigation of effective in production of poly (vinyl alcohol) (PVA) fibers fabricated from aqueous solutions of PVA.…
The present work aims at developing a class of particulate filled polymer composites consisting of epoxy as base matrix reinforced with micro-sized aluminium oxide (Al2O3) particles. A set of composites, with Al2O3 content ranging from 0 to 25 vol% have been fabricated by hand lay-up technique. Density (ρc), effective…
The effects of the surface atomic and electronic structures, oxygen defects, and hydration on CO2 adsorption on ZnGa2O4(100), (110), and (111) surfaces were studied using density functional theory (DFT) slab calculations. For the perfect (100) surface, the most stable adsorption state involved the Zn-O-Ga bridge site,…
This work reports an efficient method for the preparation of aqueous dispersions of superparamagnetic iron oxide nanoparticles (SPIONs), involving the use of an amphiphilic block copolymer, poly(ethylene glycol)-block-poly(4-vinyl pyridine) (mPEG-b-P4VP). The iron oxide nanoparticles are easily and efficiently dispers…
Multiple stimuli-responsiveness of NaDC–amino acid–NaCl mixed systems.
In order to disclose the reason that the N-doped carbon support can enhance the stability of Au-based catalysts for acetylene hydrochlorination, we established a big graphene cluster model of C110H28 to investigate the effect of different nitrogen-doped carbon supports on three kinds of gold species models of Au dimer…
We consider how to design a microfluidic system in which suspended particles spontaneously order into flowing crystals when driven by external pressure. Via theory and numerics, we find that particle-particle hydrodynamic interactions drive self-organization under suitable conditions of particle morphology and geometr…
Controlled design of nanoparticles (NPs) displaying multiple functionalities is of great interest to many applications such as targeted drug or gene delivery, diagnostic imaging, cancer theranostics, delivery of protein therapeutics, sensing chemical and biomolecular analytes in complex environments, and design of fut…
Cu(I)-catalyzed azide-alkyne cyclization (CuAAC) is the paradigmatic click reaction of continuous interest. Especially fluorogenic and FRET probes have become indispensable tools for life sciences. Here, we present a fluorescent alkyne for monitoring CuAAC, which undergoes a bathochromic shift upon reaction. Applicati…
A compound representing the first example of high dimensional and high connected hybrid based on reduced Wells-Dawson arsenotungstates has been synthesized, and its electrocatalytic and photocatalytic properties have been investigated.
Direct deposition of a uniform and high-quality Bi 2 Se 3 thin film on a graphene film (layer controlled) is performed using a catalyst-free vapor deposition system in a Se-rich environment.
