This paper presents the research undertaken at the University of Minho aiming to study the behaviour of 3D weft-knitted structures using Shape Memory Alloy (SMA) wires and elastomeric yarns, in order to produce dynamic structures as a support to answer specific situations and applications. Several samples were produce…
An electrochemical P450 model compound consisting of meso-tetraphenylporphyrinatochromium(3+) chloride (CrTPP), imidazole, and acetic acid was used in acetonitrile containing alkenes. The corresponding epoxides were obtained in better yields compared to a similar electrochemical P450 model compound using meso-tetraphe…
In this paper we present the study of electrochemical etching of silicon in KOH solutions to improve texturisation and reflection properties of p–type multi–crystalline silicon. The influence of etching temperature on surface morphology and reflection properties of the silicon wafers has been investigated. The results…
The hexagonal rotor‐like cerium carbonate hydroxide (CeCO 3 OH) and CeO 2 nanostructures were successfully synthesised via a facile hydrothermal method using Ce(NO 3 ) 3 · 6H 2 O as the cerium resource, HNO 3 additive to form an acidic solution, CO(NH 2 ) 2 as both precipitator and carbon source and polyvinylpyrrolido…
In this work an attempt has been made to synthesis polyaniline nanorods using DBSA as dopant as well as template. The formation of the material has been confirmed by FTIR and UV-Visible measurements where as surface morphology has been observed using SEM. The spin coated polyaniline film has been prepared over ITO coa…
A handful of cyano-stilbene derivatives are successfully synthesized through Williamson and Suzuki reaction. The dipole-dipole interaction of intramolecular charge-transfer molecule is used to self-assembly microstructure of the as-prepared materials. The CNS-1 microstructures are large-scale spherical particles. Howe…
By employing the theoretical model of a rigid sharp-nosed projectile perforating the ductile metallic target plate, the present paper re-analyzes the previously published experimental data of APM2 bullet and its hard steel core perforating aluminum armor plates and high-strength steel plates, respectively. Although th…
Nanoscale Fe/Ni alloy particles have been synthesized by hydrothermal method in this study. The influences of various reaction temperatures on the properties and morphologies were studied. The structure of Fe/Ni alloy nanoparticles were characterized by SEM, XRD and FTIR. Additional, the magnetic and electrical proper…
In this paper, the linear low density polyethylene (LLDPE) was melted and cross-linked by dicumyl peroxide (DCP) used to prepare cross-linked polyethylene (XPE). The gel content was determined by extraction method. The effect of content of cross-linker, cross- linked time, cross-linked temperature and other factors on…
Dielectric relaxation spectra of the blue phase-III (BP-III) of a liquid crystalline material consisting of T-shaped molecules have been investigated. A low frequency (∼kHz) relaxation mode has been observed in Isotropic as well as in BPIII phase. The outcome of the temperature variation of dielectric strength (Δε) an…
In this paper, we suggest a clean power generation process that integrates molten carbonate fuel cells (MCFC) and coal-based synthetic natural gas (SNG) production. The integrated approach achieves an increase in overall process efficiency due to recycling of the exhaust gas from the fuel cell as well as carbon dioxid…
In this study, the effects of the content of carbon black (CB) nanoparticle on the morphology of the emulsion polymer blends were investigated. The immiscible polymer blend was prepared with polystyrene (PS) and polypropylene (PP) in the absence and presence of different contents of CB nanoparticle in a twin screw min…
In this paper, a representative volume element (RVE) model of composites with different fiber volume fraction is established by ANSYS finite element software. The stiffness matrix of the RVE model can be calculated by studying its stress field, and then the elastic properties of composites could be obtained. By compar…
This contribution establishes a link between very different soft matter systems that exhibit orientational order. Granular matter research has been focused so far mainly on ensembles of spherical or irregularly shaped grains. Recently, several studies of anisometric particles have been reported, but still, many phenom…
A short-range force constant model has been applied in investigating the Raman and infrared modes in insulating Cs2HgCl4 in orthorhombic phase having space group Pnam using normal coordinate analysis. Calculations on zone centre phonons have been made with twelve stretching and three bending force constants. The calcu…
KNbO3 (KNO) nano-particles with the diameter of about 20 nm were prepared by mechanical milling using planetary ball mill from the commercial KNO powder. Rotation speeds of ball mill were 0 to 300 rpm, where the milling time was kept at 15 minutes. Magnetization was measured by SQUID magnetometer. The 250 rpm milled s…
The bed material agglomeration and heating surface high-temperature Corrosion Problems of biomass-fired boiler in South China were studied in this work. The inner and outer surfaces of the corrosion sample were investigated by scanning electron microscope (SEM) with Bruker EDX and XRD. Results showed that the outer si…
The application of Titanium alloys is more attractive today in the field of biomedical implant materials due to their superior biocompatibility and strength. Implant wear is a common phenomenon which is resulted due to high friction between artificial materials which is much higher than healthy and natural joints. The…
Diamond film and ultrananocrystalline diamond (UNCD) film were synthesized on BeCu alloy substrate by using hot filament CVD apparatus. We succeed in the synthesis of diamond film and Boron-doped electrically conductive diamond film on the substrate. Moreover, UNCD film was successfully synthesized by the CVD apparatu…
ZnO nanowires were synthesized by thermal evaporation of ZnBr2 powder at relatively low temperatures of 600–700°C under air atmosphere. Any catalysts and substrates were not used in the synthesis of ZnO nanowires. The ZnO nanowires had a typical diameter of 100 nm and lengths up to several tens micrometers. The X-ray…
