Cadmium sulphide nanoparticles were grown using a wet chemical method, by dissolving the reactants, cadmium chloride and sodium sulphide in water, in the presence of mercaptoethanol (ME), which was used as a capping agent. Manganese chloride was used to dope the nanoparticles. It was found that the particle size varie…
In this study, we synthesized styrene–methyl methacrylate copolymer particles by suspension polymerization process to study the foaming dynamics via visual batch foaming apparatus. The weight ratio of styrene–methyl methacrylate was 53–47. The foaming system consisted of a self-sealing observation cell equipped with t…
Abstract Porous biodegradable poly(ε‐caprolactone) (PCL)/clay nanocomposites were prepared by incorporating a blowing agent into the galleries of an organoclay, followed by mixing the pretreated organoclay and PCL to give partially intercalated and exfoliated nanocomposites and subsequently degrading the blowing agent…
Abstract Asymmetric polysulfone (Psf)/polyvinylpyrrolidone (PVP) hollow fiber membranes were fabricated via dry‐wet spinning process in a custom made apparatus with controlled spinneret and spinning lines temperature. This study investigated the effect of isothermal spinning temperatures on morphology, performance, an…
This paper presents an analysis of advanced cycles with limited CO2 emissions based onthe integration of molten carbonate fuel cells (MCFCs) in natural gas fired combined cycles (NGCC) in order to efficiently capture CO2 from the exhaust of the gas turbine. In the proposed cycles, the gas turbine flue gases are used a…
Abstract By using natural softwood pulp with higher degree of polymerization (DP = 1460) as cellulose source, 1‐butyl‐3‐methylimidazolium chloride ([BMIM]Cl) ionic liquid as solvent and glycerol as plasticizer, a novel cellulose packaging film was prepared. The effects of plasticization conditions on the structures, m…
Abstract The influence of the spherulite size and distribution on the fracture toughness and Izod impact strength at different temperatures of controlled‐rheology polypropylenes with 0, 154, 402, and 546 ppm of peroxide has been evaluated. As the peroxide content increased, the average spherulite size was enhanced and…
Abstract The formation of scratch‐resistant coating film prepared from colloidal silica and a polysiloxane matrix was investigated. Methyltrimethoxysilane (MTMS) was hydrolysed and mixed with silica sol (SiO 2 ) at various compositions to form the hybrid hard‐coating nanocomposite film. The hydrolysed MTMS (polysiloxa…
We investigate molecular sensitization of the nonpolar SiC(110) surface by means of density functional simulations. We focus on aromatic fragments up to a full porphyrin molecule, in view of potential application in biosensors and devices. Our results reveal a relatively low affinity between aromatic rings and the sur…
We discovered a chiral behavior of Friedel oscillations (FOs), which have both triangular symmetry and inverse chirality from chiral charge-density waves (CDWs) in 1T-TiSe${}_{2}$ by using scanning tunneling microscopy (STM). Surprisingly, the existence of FOs with the opposite chirality to the underlying CDWs suggest…
Abstract Utilization of cheap renewable carbon feedstock for polyhydroxyalkanoate (PHA) production not only brings down its production cost but also ensures sustainability. The scope of this study was to evaluate the potential of sap extracted from felled oil palm trunk (OPT) as a novel inexpensive renewable carbon so…
Abstract Measured polarization curves were used in a BEM model of the galvanic corrosion of the Mg alloy AZ31B. The AZ31B galvanostatic anodic polarization curves indicated: (i) the existence of the uni‐positive Mg + ion, (ii) some hydrogen dissolved in the AZ31B metal, and (iii) self corrosion was more important than…
Complexation of trinuclear oxo-centered carboxylates with a silicododecatungstate resulted in the formation of ionic crystals of [M(3)O(OOCC(6)H(5))(6)(H(2)O)(3)](4)[α-SiW(12)O(40)]·nH(2)O·mCH(3)COCH(3) [M = Cr (Ia), Fe (IIa)]. Treatments of Ia and IIa at 373 K in vacuo formed guest-free phases Ib and IIb, respectivel…
In this mini-review we report on current developments of hybrid materials based on semiconductor nanocrystals integrated into polymer matrices for direct light conversion, their present limitations, as well as their high potential for future applications.
There are several methods of producing open porous polymer structures for medical use. However, very few are applicable to industries and are therefore limited to both number of samples and batch variations. This study presents an industrial microcellular injection molding process, known as MuCell® technology, which w…
Abstract A‐site‐ordered perovskite‐structure oxides AA′ 3 B 4 O 12 with Cu 2+ ions at the A′ site are highlighted. Some new compounds were synthesized under high‐pressure and high‐temperature conditions. With nonmagnetic ions at the B site, only the Cu 2+ spins at the A′ site contribute to the magnetic properties, pro…

It belongs to progressive methods of model creation based on geometry obtained from CAD environment with application possibilities in different industrial spheres. Chapters…
Novel synthesis of heterocyclic liquid crystal compounds containing seven-membered 1,3-oxazepine-4,7-diones, 5,6-dihydro-1,3-oxazepane-4,7-diones, and 5,6-benzo[e] [Citation1, Citation3]oxazepine-4,7-diones rings at para position has been carried out from the reaction of maleic, succinic, and phthalic anhydrides with…
We use computer simulations to investigate the stability of a two-component polymer brush de-mixing on a curved template into phases of different morphological properties. It has been previously shown via molecular dynamics simulations that immiscible chains having different length and anchored to a cylindrical templa…
Aerosil silica nanoparticles dispersed in a liquid crystal (LC) possess the interesting property of keeping memory of an electric- or magnetic-field-induced orientation. Two types of memory have been identified: thermally erasable memory arising from the pinning of defect lines versus a "permanent" memory where the or…
