We study univalence properties for certain subclasses of univalent functions 𝔎, 𝔎2, 𝔎3, and S(p), respectively. These subclasses are associated with a generalized integral operator. The extended Becker‐typed univalence criteria will be studied for these subclasses.
The scale patterns of cashmere and fine wool are different and that is a major reference distinguishing them from each other. A technique commonly used consists of analysing their SEM image for detecting cuticle scale edge height (CSH) of fibre. However, the method is expensive and has an average error of 8%. In this…
The objective of the process is to synthesize quantum dots that will fluoresce over the visible spectrum of 450 to 650nm; then to mix the quantum dots together in a polymer matrix so that when illuminated with a blue LED the mixture yields “white” light. The current quantum dot synthesis is a chemical process that inv…
Aeromonas microorganisms normally grow at temperatures between 5 degrees C and 45 degrees C and therefore should have high thermotolerance. Thus it was of interest to find out whether A. hydrophila, A. caviae and A. veronii biovar sobria serovars respond to abrupt temperature changes with a heat shock-like response. T…
We demonstrate four-wave mixing in a silicon microresonator at low powers using a PIN diode to extract the generated carriers. We achieve conversion efficiencies as high as −6.6 dB with 7 mW of input power.
Hugoniot data for Bi are determined through measuring the impact velocity and the particle velocity at the sample/window interface on a powder gun or a two-stage light gas gun in a shock pressure range from 10 to 45 GPa, using reverse-impact geometry. The used experimental technique avoids the difficulty in accurately…
In this research, bamboo charcoal polyamide / polyurethane (BCP/PU) complex yarns and knitted fabrics were produced from bamboo charcoal polyamide textured yarn and polyurethane fibres. The polyurethane fibres were expanded and then wrapped with the bamboo charcoal polyamide textured yarn. Three manufacturing paramete…
The complete optimization task for the case of the semi-open impeller with straight blades requires description of its geometry by means of, at least, eighteen design variables. In the case of constant meridional cross-section, required are at least eight design variables. Solution of the task with such a great vector…
The present fascinating field of research is to synthesize, grow and characterize semi org. NLO crystals. Here, an attempt has been made to synthesize and grow a no. of NLO semi org. crystals. The semi org. crystals posses both the good qualities of host org. material and additive-inorg. material. The crystals grown a…
AZ31 Mg alloy in a friction stir processed condition was deformed in tension at temperatures ranging from room temperature to 300°C in comparison with the same alloy in an extruded condition. It was found that friction stir processed AZ31 possesses excellent ductility at a comparatively low thermal exposure temperatur…
The gapless and linear energy spectra of electrons and holes in graphene lead to nontrivial features such as negative dynamic conductivity in the terahertz spectral range. This paper reviews the recent advances in theoretical and experimental study on terahertz light amplification by stimulated emission of radiation i…
Highly ordered single-crystalline CuInSe2 nanowires array have been prepared via a facile solution approach by using anodic aluminium oxide (AAO) as a hard template. CuInSe2 nanowires with a novel helical shape are found to be formed by this approach. A screw-dislocation-induced growth process is proposed for the form…
A spherical nano-Si/graphite/carbon composite is synthesized, in which nanosized-silicon and flaked graphite are embedded in a carbon matrix and the flaked graphite sheets are distributed in a concentric manner with a parallel orientation. The dimensional stability of the composite electrode is investigated by examini…
Bleached kraft pulps made from 30 cm long hemp stalks, uncut hemp bast, and uncut hemp wood were prepared. Then the properties of these pulps and their fibres were analysed using the computer image analysis method. The results gave more exact knowledge of the fractional composition and fibre attributes of this raw mat…
In this study, the irreversible expansion of TATB cylinder is investigated. No evident variation of the lattice parameters is observed on TATB crystal. The density of TATB powder decreases by only about 0.02% after it suffered from thermal cycling process at the range from -54 °C to 74 °C, while the density of TATB cy…
There is an increasing interest in the sustainable supply of wood from New Zealand's plantation forests. This is due to the importance of New Zealand in global trade and uncertainty about the sustainability of supply from other countries, such as Russia. The aim of this paper is to identify important factors that infl…
Mesoporous platinum films consisting of patterned holes were deposited on yttria-stabilized zirconia via nanosphere lithography. Film morphology evolution was investigated using atomic force microscopy after annealing in either H 2 /N 2 forming gas or pure oxygen. Extracted Pt surface diffusion activation energies wer…
Single-walled carbon nanotube (SWCNT) field-effect transistors (FETs) were fabricated on strontium titanate (SrTiO 3 ) substrate through a wet-process by using amide-functionalized SWCNT. The SWCNT-FET exhibited good gate-modulation for drain current at low operating voltages (-3 V). The hole mobility was 0.19 cm 2 /V…
In the current research, an easy and inexpensive method is used to synthesize highly crystalline gallium nitride (GaN) nanowires (NWs) on two different substrates [i.e., porous zinc oxide (PZnO) and porous gallium nitride (PGaN)] on Si (111) wafer by thermal evaporation without any catalyst. Microstructural studies by…
