Low-speed marine diesel flue gas denitrification is in great demand in the ship transport industry. This research proposes an ammonia supply system which can be used for flue gas denitrification of low-speed marine diesel. In this proposed ammonia supply system, ammonium bicarbonate is selected as the ammonia carrier…
A mechanistic study on the nucleation of aggregates exhibiting a weak intermolecular coupling and high molecular mobility for major components, exampled by an entity of aniline and salicylic acid in the preparation of polyaniline microspheres (PANI-NS) and interconnected structures (PANI-NC), is explored by in situ 1…
We numerically investigate the effects of disorder on the quantum Hall effect (QHE) and the quantum phase transitions in silicene based on a lattice model. It is shown that for a clean sample, silicene exhibits an unconventional QHE near the band center, with plateaus developing at = 0, 2, 6, . . . , and a conventiona…
The corrosion inhibition of Q235 steel in HCl solution by 5,5,7,12,12,14-hexamethyl-1,4,8,11-tetra-zacyclotetradecane (HMETD) as a fully saturated macrocyclic has been studied using potentiodynamic polarization, weight loss measurement and microstructure analysis. Results indicate that the saturated macrocyclic inhibi…
In situ formation of Al2O3–ZrO2–Y2O3 composite ceramic coating on ZAlSi12Cu3Ni2 aluminum alloy was successfully prepared by plasma electrolytic oxidation (PEO) technology in a zirconate electrolytic solution. The morphologies, phase components, the thermal diffusion coefficient and thermal conductivity of the composit…
At cryogenic temperatures, the photoluminescence (PL) spectrum of nano-emitters may still be significantly broadened due to interactions with the environment. The interplay of spectral diffusion (SD) and phonon broadening in this context is still a debated issue. Singlewall carbon nanotubes (SWNTs) are a particularly…
Composite materials are heterogenous materials containing one or more solid phases. In recent years cost-effective composite making is an ideal task. Hence we have come out with a natural fibre composite, which contains goat hair and epoxy as a binding element, with the combination of Graphene as a main source of enha…
Charge transport in the temperature range 80 K < T < 300 K was studied in a composite of carbon spheres (CS), prepared via hydrothermal carbonization of sucrose, and the conducting polymer polyaniline (PANi). PANi was synthesized via the oxidative polymerization of aniline with ammonium peroxydisulfate (…
Italian solid oxide fuel cell generator manufacturer SOLIDpower is expanding its production capacity in Italy, and investing in additional SOFC research and development capabilities. And an SOFC stack supplied by the company has passed 10 years in operation at the Forschungszentrum Jülich research centre in Germany, s…
In the present study, soil algal community inhabiting in two different forest types i.e., pine forest and subtropical broadleaf forest (Mawphlang sacred grove) in East Khasi Hills District of Meghalaya have been investigated. Light availability to the forest floor and soil physico-chemical parameters were examined. A…
Zinc oxide (ZnO) rod-shaped nanoparticles are produced by the precipitation method upon the hydrolysis of zinc-nitrate hexahydrate (Zn(NO 3 ) 2 · 6H 2 O) in the presence of hexamethylenetetramine (C 6 H 12 N 4 ). The effect of various parameters on the ZnO-nanorod size and shape is shown. The ZnO nanopowders produced…
In the problem of the production silver nanoparticles, mass spectrometry allows one to identify nanoclusters as nuclei or intermediates in the synthesis of nanoparticles and to understand the mechanisms of their formation. Using low-temperature secondary emission mass spectrometry, we determined the cluster compositio…
Nickel-yttrium stabilized zirconium (Ni-YSZ) nanocomposite were synthesized by to different paths: mechanochemical method and a novel sol-gel method at different temperatures. Preliminary structural/textural results obtained by XRD, BET and SEM analyses showed a typical crystalline cubic structure, with small crystall…
The structural transformations in a nematic liquid crystal (NLC) layer with a hybrid orientation (planar director orientation is created on one substrate and homeotropic director orientation is created on the other) are studied. In the case of a dc voltage applied to the NLC layer, the primary instability is flexoelec…
A novel supramolecular liquid crystal (LC) is synthesized from the binary complex of 4-decyloxy benzoic acid and cholesteryl acetate. Fourier transform infrared (FTIR) spectroscopic study confirms the formation of intermolecular hydrogen bond between the mesogens. Various mesophases and corresponding textural changes…
Most of carbon steel are produced from hematite iron ore. The decreasing of hematite iron ore in Indonesia, encouraged iron and steel company to produced carbon steel from laterite mineral, which has high deposit in Indonesia with high grade iron (50% Fe). One of the application of laterite steel as material rooftop b…
The electronic and optical characteristics of molybdenum disulphide (MoS2) film significantly vary with its thickness, and thus a rapid and accurate estimation of the number of MoS2 layers is critical in practical applications as well as in basic researches. Various existing methods are currently available for the thi…
In this study, we have developed low-temperature curable positive-tone photo-definable dielectric materials with high elongation property for redistribution layers (RDLs). This high elongation concept introduces a flexible molecular skeleton in the base polymer backbone, which is assumed to increase the entanglement o…
