Design Conceptualization and Computational Analysis of Cryogenic Engine Nozzle-ABYOM
Abstract: The main purpose of this paper is to design a cryogenic engine nozzle with specified dimensions using CATIA V5 software and analyze the nozzle using ANSYS software. The realizable k-ε viscous model was used for calculation and the Hydrogen (H2) had retained as an ideal gas. The CFD simulations were done on the nozzle to find the pressure, density, velocity, and temperature. In the graph, there are 500 points streamlined …

Domino Reaction for the Synthesis of Nitroolefin Heterocyclic Compound Via Thiazole Formation Followed by Claisen Rearrangement
Abstract: The Baylis-Hillman adducts derived from nitroolefins have been conveniently transformed into Claisen rearrangement. These substances, which include benzothiazole moiety, are very biologically reactive substances. This novel nitro derivative of 2-((E)-2-nitro-3-phenylallyloxy)-3-ethoxybenzaldehyde was simply treated with mole percentage of 2-(2-(2-aminophenyl) disulfanyl) benzenamine in melt reactive condition. Hence this novel 2-(benzo[d]thiazol-2-yl)-6-ethoxy-4-((E)-2-nitro-3-phenylallyl)phenol core unit compounds was very intrusting and new opportunities for the preparation of closely related to the different [3,3] sigmatropic rearrangements related …

Crosslinked Starch Polymer for Coating on Fruit/Vegetable for Preservation Derived from Waste De-Oiled Soybean Cake
Abstract: Cross-linked starch films have been prepared by reacting starch extracted from de-oiled soybean cake (waste material from oil industry) with bio-based acids citric acid and tartaric acid. The obtained films were characterized by spectroscopic, thermal and surface morphological techniques. Thermal analysis showed that thin film has good thermal stability. The micrographs obtained from scanning electron microscopy showed the film surface has smooth and uniform morphology. Biological properties like cytocompatibility, antimicrobial …

The Practical Use of Cholesteric Liquid Crystal Film for Development of New Technologies
Abstract: The use of cholesteric liquid crystal films, using the remarkable property of cholesteric liquid crystals to change their color at the temperature changes, is well known for measuring temperature, in medicine, in jewelry and so on. The article presents the practical use of cholesteric liquid crystal films in the developed musical color device, which “animates” the pattern with a multi-colored color in accordance with the frequency spectrum of the signal …

Synthesis of Green Nanoparticles for Degradation of Cellulose
Abstract: Late advances in nano-science and technology have also prompted the advance of novel nanomaterials, which eventually increment potential eudaimonia and ecological perils. Enthusiasm for growing Earth's thoughtful ways for the mix of auriferous nanoparticles has been enlarged. The intention is to limit the negative effects of the designed methodology with artificial compounds and subordinate mixes. The abuse of assorted biomaterials for the mix of nanoparticles is a profitable methodology in …

Cyber Security Evaluation for a Petroleum Refinery Using Attack Tree Methodology and Economic Indexes
Abstract: Information Technology (IT) is vital and valuable to our society. An important type of IT system is Supervisory Control and Data Acquisition (SCADA) systems. The most common misconception regarding the security of SCADA was that this network was electronically isolated from other networks and hence attackers could not access them. Over the years SCADA systems have become incorporated with other IT systems, which has made them becoming increasingly vulnerable to …

Synthesis and Evaluation of New Coumarin Derivatives for Inflammatory Bowel Disease Against DSS-Induced Acute Ulcerative Colitis Mice Model
Abstract: Objective: The discovery of the now numerous mouse models of intestinal inflammation has increased our understanding of the intestinal inflammation that occurs in inflammatory bowel disorders (IBD). This study aimed to investigate the use of a standardized animal model subjected to coumarin derivative treatment, and the action of synthesized molecule administration of dextran sodium sulphate (DSS)- induced colitis in experimental mice. Materials and Methods: We generated a variety of unique …

Zeolite-Y Encapsulated Copper (II) and Cobalt (II) Species as Hybrid Nano-catalysts: Structural and Catalytic Aspects
Abstract: Special properties inherent to zeolites in facilitating the construction of novel upramolecular assemblies by encapsulation of guest molecules (metal complexes) into their large cages can be utilized to use these assembled materials as novel catalysts. These modified solids have the advantages of both behaving as the homogeneous and the heterogeneous catalytic system. In the present work, copper (II) and cobalt (II) complexes of 2-amino ethanoic acid (2-AEA) encapsulated in the …

Advanced Quantitative Analysis of Dynamic Recovery during Warm Working of FCC Alloys
Abstract: Metal working processes of warm working require an advanced quantitative analysis of dynamic and static recovery of dislocations to control microstructures and crucial shape forming properties. Feasibility of dynamic recovery by thermal glide and static recovery by climb of constricted jogs, applicable to ausforming, nano bulk forming by SPD and normalizing has been addressed to design new steels, used for hulls, and tribologically superior bearings. Predictive dislocation recovery analysis shows …

Influence of Crystallization Time by Hydrothermal Synthesis of Ag NPs-Zeolite Composite
Abstract: The nanocomposites Ag NPs-zeolite involve zeolite loaded with silver nanoparticles and have been prepared by an easy one-pot hydrothermal autoclave method. Three samples of silver-bearing zeolite were prepared for 8 hours, 6 hours, and 4 hours, respectively, inside an autoclave at 100°C. A range of characterization procedures were used to examine the samples, such as x-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), UV-visible spectroscopy, and zeta potential. Results …

Synthesis, Characterization and Antibacterial Activity of Mono- and Binuclear Co(II) and Cr(III) Mixed-Ligand Complexes Derived from α-Amino Acid and 1,10- Phenanthroline with 1,3-Diaminopropan as a Spacer
Abstract: Mixed-ligand complexes of Co(II) and Cr(III) ions were synthesized from the reaction of metals chloride salts with α-amino acid (H2L1) as a primary ligand and 1,10-phenanthroline (L2) as secondary ligand. The ligand 2-(benzo[d]thiazol-2-ylamino)-2-(2-hydroxynaphthalen-1-yl) acetic acid (H2L1) has been synthesized from the condensation reaction of inobenzothiazol with 2-hydroxy-1-naphthaldehyde in the presence of HCN as three components–one pot reaction. H2L1 considered as a tridentate chelater of ONO-coordination binding type toward the metals, …
