Polysaccharides from marine sources have been increasingly used in recent research due to their availability, affordability, biocompatibility, and biodegradability. These features make them promising candidates for use in nanotechnology in a wide variety of drug delivery systems, including those for gene therapy, tissue engineering, cancer therapy, wound dressing, biosensors, and water purification. Marine polysaccharides Read More

BackgroundCeria (CeO2) belongs to rare-earth series and due to its profitable properties, presents a wide commercial use such as catalysis, energy, biological, biomedical, and pharmaceutical. The features of the starting materials in the form of free powders influence notably the processing, formation, as well as characteristics of the final structures\bodies obtained by colloidal processing. This study aims to charac Read More

BackgroundOur country has dramatically evolved over the decades, and now we have a large number of well-connected roads, public buildings and a rising number of automobiles. With the passage of time, the manual car parking system in commercial spaces has become a stumbling block and wastes time. As a result, it requires a solution that can address these issues. Automated car parking systems are the answer to these iss Read More

IntroductionIn this research work, an attempt was made to machine Ti6Al4V nano composites utilizing Al2O3 mixed nano fluid at minimum quantity lubrication condition, in which experiments were designed using the L16 orthogonal array, whereas Material Removal Rate, Surface Roughness, machining force and power were recorded as responses.MethodsThe nano composites were fabricated using the stir casting technique Read More

AimsIn this paper, we aimed to prepare SiC-CDC with porous structure from SiC precursor by using simple molten salt electrochemical etching method at 900 ºC in argon at an applied constant voltage of 3.0 V.BackgroundNanoporous materials include carbon materials, silica or alumina, gel, and zeolite, which have been known since ancient times. Among all these materials, carbon materials are particularly outstanding. I Read More

In the current study, nanocrystalline LaMnO3 perovskite was prepared by combustion method and annealed at different annealing temperatures. The X-ray diffraction (XRD) patterns provided evidence that the structure formed has a Rhombohedral structure with R3 ̅c space group. The remarkable growth in the crystallite size, reduction in microstrain, and dislocation density were observed with annealing temperature. Ul Read More

IntroductionThis work represents the influence of gate dielectric, and the nano-cavity gap of a dielectric modulated trench gate Junction-less Double Gate Field Effect Transistor (JL-DGFET) on the different performance indicators is investigated considering the Low-Frequency Noise.MethodsIt is noted that the gate dielectric and the nanogap, both parameters, have a substantial influence on the sensing capacit Read More

IntroductionA steel frame system becomes structurally less efficient when subjected to large lateral loads such as a strong wind or a severe earthquake. Several techniques could enhance the structural performance against these lateral loads, including single diagonal and X-bracing systems, moment-resisting frames, and viscous dampers.MethodsThis study aimed to compare these techniques' ability to reduce the st Read More

BackgroundThe spindle top is an important component used to withstand the shaft workpiece on machine tools so that the spindle can meet high efficiency and high precision requirements. However, the selection principles under various load conditions are not stipulated in use. In addition, material selection, manufacturing, heat treatment technology, etc., are of practical significance for the production of high hardness, hig Read More
