With a facile solvothermal method, Ag@Fe 3 O 4 nanowire was successfully prepared and characterized by X‐ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The obtained Ag@Fe 3 O 4 nanowire posses enhanced peroxidase‐like activity with good stability and high absorba…
The effect of thermo-mechanical treatment on the mechanical properties of a novel β-type Ti–36Nb–5Zr (wt%) alloy has been investigated. The solution treated alloy consists of β and α″ phases and exhibits a two-stage yielding with a low yield stress (around 100 MPa). After cold rolling at a reduction of 87.5% and subse…
The objectives of this study were to evaluate physical properties and antibacterial activity of a light-activated composite modified with silver nanoparticles. Discs were produced with unmodified resin (control group - CG) and modified resin with silver nanoparticles at two concentrations, 0.3% wt (MR03) and 0.6% wt (…
Nickel ferrite (NiFe 2 O 4 ) is a major constituent of the corrosion deposits formed on the exterior of nuclear fuel cladding tubes during operation. NiFe 2 O 4 has attracted much recent interest, mainly due to the impact of these deposits, known as CRUD, on the operation of commercial nuclear reactors. Although advan…
Metal-organic framework materials (MOFs) have recently been shown in some cases to exhibit strong negative thermal expansion (NTE) behavior, while framework interpenetration has been found to reduce NTE in many materials. Using powder and single-crystal diffraction methods we investigate the thermal expansion behavior…
To realize nanocarbons in general and carbon nanotube (CNT) in particular as on-chip interconnect materials, the contact resistance stemming from the metal–CNT interface must be well understood and minimized. Understanding the complex mechanisms at the interface can lead to effective contact resistance reduction. In t…
One approach to increase the low thermal conductivity of polymers is to add nanosized or microsized fillers with relatively high thermal conductivity. The concept of nanodielectrics is based on the fact that the dielectric behaviour of polymeric composites is tailored on or dictated by nanoscale manipulation. In this…
Traditional pesticide residue detection methods are usually complicated, time consuming, and expensive. Rapid, portable, online, and real-time detection kits are the developing direction of pesticide testing. In this paper, we used a surface-enhanced Raman spectroscopy (SERS) technique to detect the organophosphate pe…
A series of Mg 2 Al x V 1– x –LDH (LDH = layered double hydroxide) was synthesized by using a facile method, and well-mixed derived oxides were obtained after calcinations. These catalysts were further tested for H 2 S selective oxidation. Meanwhile, the physicochemical properties of the catalysts were investigated by…
The subject matter of this paper refers to the improvement of the acoustic emission (AE) method when used for detection, measurement and location of partial discharges (PDs) in oil insulation systems of power appliances. In particular, presents the basic assumptions and describe the individual elements of an expert di…
There are various applications for shape memory polymer (SMP) in the smart materials and structures field due to its large recoverable strain and controllable driving method. The mechanical shape memory deformation mechanism is so obscure that many samples and test schemes have to be tried in order to verify a final d…
Abstract Conjugated microporous polymers (CMPs), in which rigid building blocks form robust networks, are usually synthesized as insoluble and unprocessable powders. We developed a methodology using electropolymerization for the synthesis of thin CMP films. The thickness of these films is synthetically controllable, r…
Thermoplastic polyurethane (PU) elastomer, prepared from poly(tetramethylene glycol) and methyl diphenyl diisocyanate, was blended with boron nitride (BN) to fabricate a thermally conductive interface material. BN treated by a silane coupling agent (BN―NH2) and PU-grafted BN were prepared to fabricate a composite that…
ABO3 perovskites with small cations at the A site (A = Sc(3+), In(3+) and Mn(2+) and B = Al(3+) and transition metals) are reviewed. They extend the corresponding families of perovskites with A(3+) = Y, La-Lu, and Bi and A(2+) = Cd, Ca, Sr and Ba and exhibit the largest structural distortions. As a result of these lar…
Free moving metallic particles are one of the most common defects leading to insulation failures in gas insulated substation (GIS) equipment. The present research is designed to diagnose and assess the severity levels of partial discharge (PD) initiated by free moving metallic particles on GIS insulator surface. On a…
New water-soluble nontoxic nanocomposites of nanosized silver particles in a polymer matrix were synthesized by a green chemistry method. Nontoxic poly(1-vinyl-1,2,4-triazole) was used as a stabilizing precursor agent in aqueous medium. Glucose and dimethyl sulfoxide were used as the silver ion-reducing agents to yiel…
We fabricated zinc oxide (ZnO) nanorods (NRs) with ZnO seed layers by using the sol-gel solution method with various annealing temperatures on different substrate materials (silicon, glass, and fluorine doped tin oxide (FTO) coated glass). Within a certain range of seed annealing temperatures, the alignment and length…
This paper focuses on the effect of nanoparticle surface modification on the charge transport characteristics in XLPE/SiO2nanocomposites. A titanate coupling agent (TC9) and a 3- (Methacryloyloxy)propyltrimethoxysilane (KH570) were used for the surface modification of SiO2nanoparticles. It was found that both KH570 an…
The First Mirror Test in Joint European Torus (JET) with the International Thermonuclear Experimental Reactor-like wall was performed with polycrystalline molybdenum mirrors. Two major types of experiments were done. Using a reciprocating probe system in the main chamber, a short-term exposure was made during a 0.3 h…
