In the last few years, there has been an explosion of user cases involving the location of consumer electronics devices such as smartphones, tablets and wearable devices. This need for positioning and navigation has extended from outdoors where GNSS provides high quality service to indoor areas where it is inadequate.…
Abstract The sol gel method was used in preparing a series of A site partially substituted La1−xBaxCoO3 (x ≥ 0.1 ≤ 0.4) perovskite catalysts coded LBC1, 2, 3, and 4 and their potential as catalysts for soot oxidation were evaluated. The Brunauer–Emmett–Teller (BET), Inductively Coupled Plasma Atomic Emission Spectrosc…
Abstract The aim of this work was to obtain a π-conjugated organic semiconductor with the macrocycle Ni(II)(TAAB) ([tetrabenzo (b, f, j, n) [1,5,9,13]tetraazacyclohexadecine]Ni(II) and the electronic acceptor TCNQ (tetracyano-π-quinodimethane), in which hydrogen bonds are formed between TCNQ and Ni(II)(TAAB). Theoreti…
Abstract Possibility of application fibrous additives of a natural origin in an ice matrix as the reinforcing additives is investigated. As a matrix, fresh ice water was used, reinforcing additives — hay fiber 10 mm long and 0.5–1 mm thick and basalt fiber produced by Plant of Basalt Materials LLC (Pokrovsk, Sakha Rep…
In this paper electrical and thermal conductivity coefficients of heavily doped n-Silicon have been derived based on parabolic and modified density of states having band tails. The derivation uses Boltzmann transport equation with relaxation time arising from ionized impurity scattering mechanism as a dominant scatter…
Abstract Montair and Belgoprocess developed the pilot PRIME (Pyrolysis Resins In Mobile Electric) Installation for treatment of spent resins in one single reactor without pre-treatment and without intermixing of other waste, allowing for easy traceability and isotopic characterization of the end product. Both low leve…
Abstract Curved liquid crystal display (LCD) suffers from an issue of uneven brightness among the vertical‐alignment LCD panels based on thin glass substrates. In this work, we investigated its origin through optical simulation and successfully realized uniform brilliance for 27‐inch curved LCD panels. The optical sim…
Viscosity-temperature characteristics of high borosilicate glass were investigated in detail by means of rotor viscometer and dilatometer. The neck-down deformation process of glass tube was simulated by Polyflow software, and the simulation was verified by the secondary drawing of glass perform. The results showed th…
PbS synthesized at the same condition with PbSe exhibits an opposite electrical conduction type from it. Via the solid solution of PbS into PbSe, we attempt to change the major carries kind of PbSe-base materials and improve the thermoelectric (TE) property of synthesis samples in corresponding temperature areas. Intr…
Abstract Nonlinear optical microscopy techniques have been used to study thin films of single-phase (perovskite) and two-phase (perovskite–pyrochlore) lead zirconate titanate (PZT) deposited on Pt/TiO2/SiO2/Si by means of radio-frequency magnetron sputtering at various target–substrate distances (D = 30–70 mm). Result…
Abstract Chrome‐manganese‐nitrogen austenitic steels show a technically relevant combination of proprties, i. e. high strength, high ductility, non magnetic and good corrosion resistance at costs being much lower compared to conventional chrome‐nickel austenitic stainless steels which are widely used for hydrogen appl…
A chemical vapor deposition method has been proven to produce large scale monolayer graphene. However, it is often reported that such graphene contains a varying amount of defects. In this work, methane precursors of different purities [99.99% (4-9G), 99.90% (3-9G), and 98.90% (2-9G)] were used. It is shown that the i…

Abstract Synthesis of eugenol-divinylbenzene copolymers were carried out by reacting eugenol with various percent weight of divinylbenzene in a reactor at room temperature for 24 hours in the presence of sulfuric acid as a catalyst. Methanol was used to quench the copolymerization process. The effect of DVB mass on co…
Abstract The atmospheric pressure plasma enhanced chemical vapor deposition method was used to study the enhancement of the particle growth and thin layer deposition. For this purpose, an atmospheric pressure plasma jet was used to deposit silicon oxide compounds on a (100)-silicon wafer substrate. In this parametric…
Abstract Chlorine is usually present in the environment in an ionic state, is highly mobile and difficult to degrade. High-chlorine wastewater can corrode buildings and affect the growth of animals and plants. Therefore, how to solve the environmental problem of high concentration of chloride ions well and effectively…
Abstract Polyethylene film properties can be manipulated by blending linear low‐density polyethylene (LLDPE) with low density polyethylene (LDPE) resin. The accurate determination of LDPE content in those blends, however, is challenging. Differential scanning calorimetry analysis has been traditionally used to determi…
Abstract The results of theoretical studies on the power balance of infrared radiation during heating of type II auto body parts is provided. A mathematical model of heating of auto body parts coated by a polymer during infrared processing has been simulated, and comparative calculation and experimental data on temper…
Scanningelectron microscopy (SEM) has been utilized to examine the morphology and topography alterations in the surface of Poly(Lactic Acid)(PLA) fabrics due to UV/Ozoneirradiation. In the past decade, a growing attention in the usage of “Green Techniques” in industrial applications has been observed owing to many ben…
The objective of the present work was to characterize the morphological, geochemical and mineralogical features of soil with regard to weathering processes as a function of topography and spatial variation of climate in tropical high reliefs of Cameroon. Field investigations permit to select three study sites Mbalam,…
