The noise generated by rotating machines and electrical transformers is harmful and its reduction has been the subject of several studies. Such systems are likely to come into resonance and become noisier. This resonance may come from mechanical or magnetic forces. The phenomenon of resonance is usually studied only i…
isomers depends on the cation employed and/or the number and type of co-crystallized solvent molecules. Often, mixtures of the two isomers, within the same single crystal or as mixtures of different crystals within the same crystallization batch, are obtained. Structural isomerism in organometallic nanoclusters is dis…
Graphene field-effect transistors (G-FETs) on flexible substrates have demonstrated much higher strain limits than that on rigid substrates. In this letter, G-FETs with an extrinsic fmaxof 28 GHz on flexible polyethylene terephthalate (PET) substrates are presented. Polyimide film benzocyclobutene with 50-nm thickness…
ABSTRACT Fabrication of hybrid composite of nickel oxide (NiO) combined with oil palm empty fruit bunch (OPEFB) reinforced with polycaprolactone (PCL) has been done by using thermal Haake blending machine, which ensured mixture homogeneity. All hybrid composites' characterizations were carried out using X‐ray diffract…
Oxidizing aldehydes to generate carboxylic acids is a crucial reaction in nature and in chemical industry. The aldehyde oxidation, an easily achieved process in liver cells, is inert towards autoxidation in industrial production and difficultly achieved under enzymatic condition (in water, at pH 7, at room temperature…
Shape-tunable and facile extracellular green synthesis of silver nanocubes using leaf extracts of Jatropa Gossypifolia and Jatropa Glandulifera and its antibacterial studies, Jeyapaul, U, Kala, S Mary Jelastin, Bosco, A John, Kalaivizhi, R, Prakash, P, Easuraja, M, Harish, S
We report the design and implementation of a one-dimensional guided-mode resonance filter (1D-GMRF) aiming to achieve polarization insensitivity at conical mounting. (The incident plane is aligned neither perpendicularly nor parallelly to the grating bars.) The design guideline indicates that, at conical mounting, pol…
A step-shear deformation imparts an instantaneous, anisotropic stimulus onto a microphase-separated block copolymer mesophase. In response to the concomitant molecular stretching and collective deformation of the morphology, the system relaxes toward a long-lived, pseudometastable state with a minuscule residual shear…
Abstract Capsaicin (CAP) ist seit Längerem für dessen analgetische Wirkung sowie seit Kurzem für seine Antitumoraktivität an verschiedenen Zelltypen bekannt. Aufgrund seiner Schärfe und der benötigten hohen Dosen zur Erzielung einer signifikanten Aktivität hat dieser Wirkstoff bis heute keine Anwendung in der Krebsthe…
Abstract The microstructure of aragonite, one of the main bio-mineral and component of bio-inspired materials, was described in numerous investigations. Using transmission electron microscopy (TEM), for the first time we show the effect of temperature on aragonite microstructure. The local increase of (0.5 0.5 0) refl…
Abstract The glass‐forming region of the BaO‐La 2 O 3 ‐B 2 O 3 ternary system was determined by using a containerless processing. Moreover, we prepared x BaF 2 ‐(35‐ x )BaO‐15La 2 O 3 ‐50B 2 O 3 ( x = 0‐35 mol%), x BaF 2 ‐(20‐ x )BaO‐20La 2 O 3 ‐60B 2 O 3 ( x = 0‐20 mol%), x BaF 2 ‐(20‐ x )BaO‐15La 2 O 3 ‐65B 2 O 3 (…
ABSTRACT A series of novel aqueously soluble semi‐aromatic (co)polyamides, poly[(ethylenedioxy)bis(ethylene) terephthalamide]‐ ran ‐poly[(ethylenedioxy)bis(ethylene) (2,5‐dihydroxy‐3,6‐diallyl)terephthalamide] (CRPAOT‐x), were prepared via the solid‐state Claisen rearrangement reaction of poly[(ethylenedioxy)bis(ethyl…
New silver nanocomposites (AgNCs) based on copolymers of N ‐vinylpyrrolidone with N,N‐diallyl‐N′‐acetylhydrazine, poly (VP‐DAAH), and 3‐methacryloxytetrahydrothiophenedioxide‐1,1, poly (VP‐MTT), have been developed. The reduction of silver ions into silver nanoparticles was achieved using NaBH 4 as reducing agent. UV‐…
Flexoelectricity describes the coupling between polarization and strain gradients and presents a strong size dependence at nanoscale. In the current work, based on the extended linear piezoelectricity theory with flexoelectricity, we study bending of piezoelectric beams with consideration of flexoelectric effect. When…
In our previous studies, CuCl 2 showed excellent removal efficiency for trace phosphine in circular hydrogen of a polysilicon chemical vapor decomposition (CVD) stove. In this study, the investigation of properties and performances of CuCl 2 supported on γ-Al 2 O 3 with high surface area were conducted. Various charac…
Abstract The solubility of 2-chloro-3-(trifluoromethyl)pyridine (CTP) in ethyl acetate, n-butyl alcohol, 2‑propanol, methanol, trichloromethane, acetonitrile, and acetone under atmospheric pressure was measured at 273.15–303.15 K. The solubility of CTP in all eight solvents increased with the increase in temperature.…
Abstract One‐pot synthesis of polymeric nanostructures, by using ultrasound without adding initiators and surfactants, is a straightforward approach that has attracted significant attention in polymer science. In this study, the ultrasonic polymerization technique is employed to synthesize poly(ethylene glycol) based…
The structure regulation of cuprous oxide (Cu 2 O) has been realized from submicrometric cubes to irregular hollow polyhedrons and hollow truncated octahedrons. It is suggested that the evolution of Cu 2 O exotic morphology and hollow structure are caused by an inside–out Ostwald ripening mechanism in the synthetic sy…
In this work, we demonstrate a simple approach for growing 1D (one-dimensional) inorganic chains of K(C 6 H 16 N) 3 Mo 8 O 26 ·H 2 O polyoxometalates (POMs) from its colloidal soft-oxometalate (SOM) phase through the variation of pH. The structure is composed mainly of a 1D inorganic chain with a β-Mo 8 O 26 4− bindin…
The detailed analysis of resistivity $(\ensuremath{\rho})$ for single-crystalline ${\mathrm{EuTi}}_{1\ensuremath{-}x}{\mathrm{Nb}}_{x}{\mathrm{O}}_{3}\phantom{\rule{4pt}{0ex}}(x=0.10$--0.20), an itinerant ferromagnet with very low Curie temperature $({T}_{C})$, reveals that the charge conduction in this system is extr…
