Compressive high-strain rate behavior of thermoset epoxy resin dispersed with multi-walled carbon nanotubes is presented. The present study investigates the effect of strain rate as well as effect of multi-walled carbon nanotube dispersion on the compressive stress–compressive strain behavior of thermoset epoxy resin.…
To better understand the influence of carbonization of the Ti interlayer on diamond nucleation and growth, a series of Ti/diamond composite films were deposited on cemented carbide (WC:Co) substrates using a two-step deposition technique. The microstructural properties of the composite films were then characterized by…
The chemical bath deposition (CBD) and the grain boundary diffusion method were combined to diffuse the heavy rare earth for obtain the thick magnets with high coercivity and low heavy rare earth. The jet mill powders were soaked into the alcohol solution of 0.2 wt. % TbCl3. A thin layer of TbCl3 was wrapped to the su…
Expanded graphite (EG) was added to polylactic acid (PLA) and then fully mixed in a novel elongational mixing device (RMX) to obtain PLA/EG nanocomposites. The operation of the new mixer device is based on the induced multiple passages of material (by means of reciprocating pistons) at different flow speeds through a…
The efficiency of tin(II) 2-ethylhexanoate catalyst and hydrophilic silica nanoparticles in compatibilizing polycarbonate/poly(methyl methacrylate) (PMMA/PC) blends were compared in terms of the morphological, thermal, and mechanical properties. Both the catalyst and nanoparticles were found to refine the morphology o…
Thin films of β-Ga2O3 are prepared on sapphire substrates via electron beam evaporation and annealed at 1000 °C for 1 h. The effect of the annealing treatment upon the crystal structures, surface morphologies, and optical properties of β-Ga2O3 films are investigated by x-ray diffraction, scanning electron microscopy,…
Metal clusters featuring closed supershells or aromatic character usually exhibit remarkably enhanced stability in their cluster series. However, not all stable clusters are subject to these fundamental constraints. Here, by employing photoelectron imaging spectroscopy and ab initio calculations, we present experiment…
Surface-enhanced Raman scattering is an effective analytical method that has been intensively applied in the field of identification of organic molecules from Raman spectra at very low concentrations. The Raman signal enhancement that makes this method attractive is usually ascribed to the noble metal nanoparticle (NM…
ABSTRACT Essential oils (EOs) have a long history as food preservatives and many advantages compared to synthetic preservatives. The major limitation of EOs as antimicrobial agents incorporated into a polymeric matrix is their low thermal stability and their high volatility from polymers. This study suggests a new met…
Perovskite-type BaZr0.1Ce0.7Y0.1M0.1O3-δ (M = Fe, Ni, Co and Yb) (BZCY-M) oxides were synthesized using the conventional solid-state reaction method at 1350-1550 oC in air in order to investigate the effect of dopants on sintering, crystal structure, chemical stability under CO2 and H2S, and electrical transport prope…
The aim of this report is to describe the Seitz notation for symmetry operations adopted by the Commission on Crystallographic Nomenclature as the standard convention for Seitz symbolism of the International Union of Crystallography. The established notation follows the existing crystallographic conventions in the des…
It has been widely recognized that the combination of carbon nanotube (CNT) and liquid crystals (LCs) not only provides a useful way to align CNTs, but also dramatically enhances the order in the LC phases, which is especially useful in liquid crystal display (LCD) technology. As the measure of this phase behavior, th…
A new theoretical approach to find metal-cluster-catalyzed single bond activation pathways is introduced. The proposed approach combines two automated reaction path search techniques: the anharmonic downward distortion following (ADDF) and the artificial force induced reaction (AFIR) methods, developed in our previous…
Bulk anisotropic composite magnets based on MnBi/Co(Fe) exhibiting the different morphology of the soft magnetic phase were prepared by powder metallurgy processing. First, single-phase MnBi bulk magnets were produced with a maximum energy product [(BH)m] of 6.3 MGOe at room temperature. The nanoscale soft phase with…
In order to find an alternative to long perfluorinated chains in the elaboration of non‐wetting surfaces with favorable bioaccumulative potential, we report the synthesis of an original 3,4‐propylenedioxythiophene (ProDOT) derivative containing a short perfluorobutyl chain (C 4 F 9 ) and its use for the elaboration of…
A maximum of more than 40 g of acetaminophen Form II crystals with a yield of 65 mol % is made reproducibly in a 500 mL reactor by coupling the acetylation of p -aminophenol with the neutralization of acetic acid before the crystallization of acetaminophen Form II crystals. This novel working principle involves a sudd…
The temperature-induced stepwise neutral-ionic (N-I) phase transition in the covalently bonded donor-acceptor chain compound [Ru2 (2,3,5,6-F4 PhCO2 )4 DMDCNQI]⋅ 2(p-xylene) (2,3,5,6-F4 PhCO2 (-) =2,3,5,6-tetrafluorobenzoate; DMDCNQI=2,5-dimethyl-N,N'-dicyanoquinodiimine) was systematically tuned over a wide temperatur…
BACKGROUND: Controlled and local drug delivery systems of anti-inflammatory agents are drawing increasing attention thanks to their possible pharmaceutical and biomedical applications. These systems have extended therapeutic effects and reduced side effects. METHODS: A single-step sol-gel process was used to prepare o…
In order to improve the lymphatic targeting efficiency of anti-cancer agent vincristine sulfate (VCR), the poly (butylcyanoacrylate) nanoparticles (VCR-PBCA-NPs) were prepared by emulsion polymerization and modified superficially with Pluronic F127. These prepared nanoparticles with (F127-VCR-PBCA-NPs) and without sur…
Electromigration of copper in integrated circuits leads to device failure. Potential solutions involve capping the copper with ultrathin cobalt films. We report the properties of cobalt films after deposition on polycrystalline Cu at 265 °C by atomic layer deposition from H2 and bis(N-tert-butyl-N'-ethylpropionamidina…
