In this work, optimization model has been developed to simulate TEG (Thermoelectric generator) based power generation system. Proposed model able to predict the gross power, net power and pumping power for all operating conditions and heat exchanger dimensions. Model also able to choose the optimum operating condition…
IMO issued latest environmental regulations Tier Ⅲ has strengthened the emission standards, in which the NOx emission should be less than 3.4g/(kWh) for marine two-stroke engines (engine speed lower than 130r/min) in NOx ECAs. In order to meet the strengthened emission regulations, EGR and fuel injection strategies ha…
In this study, the three microstructure of the as-cast, hot-extruded, and 3D printed Mg-4Y-3RE-Zr (WE43) magnesium alloy was studied. The selective laser melting (SLM) process was used for 3D printing. The study was aimed at mapping the microstructure of a 3D printed magnesium alloy produced by the SLM process. Magnes…
The possibilities to influence the 4 major phase transitions of isotactic polybutene – 1 (iPB-1) and their transformation rate are described. The phase transformations result in new polymer structures with new physical and, in some cases, practically important properties. The transformation of phase II to I is spontan…
We present a flexible setup for determining the rheology of visco-elastic materials which is based on the mechanical response of a magnet deposited at the surface of a slab of material and excited electromagnetically. An interferometric measurement of the magnet displacement allows one to reach an excellent accuracy o…
High Resolution Image Download MS PowerPoint Slide Poly(2-isopropyl-2-oxazoline)- b -poly(lactide) (PiPOx- b -PLA) diblock copolymers comprise two miscible blocks: the hydrophilic and thermosensitive PiPOx and the hydrophobic PLA, a biocompatible and biodegradable polyester. They self-assemble in water, forming stable…
The static hysteresis characteristics of soft magnetic materials were measured by the static performance testing system (SPTS). With a toroidal-shape specimen and Epstein frame, the DC magnetizations of different forms of magnetic steel sheet and grain-oriented (GO) silicon steel sheet can be realized by setting a DC…
The Municipal Company of Urban Cleaning uses plastic lumber to manufacture urban furniture items, whose process generates a post industrial waste scrap that is recycled once again. The Fábrica Carioca de Catalisadores produces catalysts for oil cracking in fluidized bed. This production process creates an inorganic so…
Korea's first commercial nuclear power plant at Kori site was permanently shut down in 2017 and is currently in transition stage. Preparatory activities for decommissioning such as historical site assessment, characterization, and dismantling design are being actively carried out for successful D&D (Dismantling and De…
The influence of thermoplastic starch (TPS) and babassu mesocarp incorporation on the biodegradation of poly(butylene adipate‐ co ‐terephthalate), PBAT, PBAT/TPS blend, and its biocomposite were investigated. PBAT/TPS blend (70:30) and its biocomposite containing 20% babassu (i.e., 17:58:25% wt/wt babassu mesocarp/PBA…
It is of immense interest to exert spatial and temporal control of chemical reactions. It is now demonstrated that irradiation can trigger reactions specifically at the surface of a simple colloidal construct, obtained by adsorbing polyethyleneimine on fluorescent colloidal particles. Exciting the fluorescent dye in t…
By combining an atomistic valence force field approach and calculations based on the effective-mass approximation, we investigate the influence of strain effects on the band alignment and general excitonic properties of core/shell CdSe/CdS dot/rod nanoparticles. We find that the inclusion of strain effects leads to an…
The present research, studies the effect of adding two different types of reinforcing powders, which included: Bamboo (Ba) and Rice Husk (RH), that added with different weight fractions (2, 4, 6 and 8 wt. %), and with the selected size particles of (25µm and 75µm) on thermal behavior of heat Cure Poly (Methyl Methacry…
Possibility of forming a gas-tight thin-film solid electrolyte by the electrophoretic deposition method on a modified multilayer cathode was examined. The main goal of the study was to find such technological parameters at which the resulting structure of the cathode substrate would make it possible to preserve its po…
In the current study, two quinazoline derivatives di-cationic surfactants, that contain long carbon chain, have been synthesized. Their structures were supported by spectroscopic methods, and their anticorrosive protection on mild steel was tested in acidic medium at room temperature for 24 h. Corrosion processes were…
Room-temperature control and detection of the nitrogen vacancy (NV) center in diamond's spin-state has enabled magnetic sensing with high sensitivity and spatial resolution [1], [2]. However, current NV sensing apparatuses use bulky off-the-shelf components, which greatly increase the system's scale. In [3], a compact…
Introduction: In this work, we have developed a novel “confined-growth” strategy to synthesize PEGylated multiple gold nanorices-encapsulated dual-mesoporous silica nanospheres (designated as PEGylated [email protected] ) containing both small mesopores (2.5 nm) in the shell and large mesopores (21.7 nm) in the core b…
One method that can produce nanoparticle material is the spray pyrolysis method, but the use of a spray system requires a high temperature heating or pyrolisis system therefore a furnace is needed which can reach high temperatures. The built furnace has a vertical elongated turbular type with dimensions measuring 60 c…
Graphene is a carbon material with excellent properties, which makes it applicable in a myriad of applications. However, the range of the applications of graphene can be extended to the developing field of nanoelectronics and optoelectronics by doping it with heteroatoms. In this study, Be and S atoms were used to co-…
The perovskite-type oxide La o.9 Sr o.1 Fe 1-x Mo x O 3 (LSFMO) with x = 0.1, 0.2, and 0.3 were successfully prepared by sol-gel method. The synthesized perovskite has been characterized by Fourier transformed infrared spectroscopy (FTIR) and UV-Vis spectroscopy for further studies. FTIR spectra confirm the presence o…
