Nano-Chemical Revolution in Vaccinology: A Study
Abstract: The development of traditional vaccines, reliant on attenuated pathogens or purified proteins, has historically been limited by slow development timelines, poor stability, and low immunogenicity requiring potent, often non-specific, adjuvants. This synthesis argues that the convergence of nano-material science and meticulous chemical engineering represents the next major paradigm shift in preventative medicine. Nano-materials, particularly Lipid Nanoparticles (LNPs) and various polymeric or inorganic scaffolds, have transitioned from theoretical constructs to essential …

SoloRider: An Autonomous Self-Balancing Electric Bike for Sustainable Urban Mobility
Abstract: Rapid urbanization has intensified challenges such as traffic congestion, parking inefficiency, and environmental degradation. While autonomous vehicle research predominantly focuses on four-wheel platforms, lightweight two-wheelers remain comparatively underexplored. Two-wheelers are a great option for sustainable urban transportation because of their many benefits, including their small size, lower energy consumption, better manoeuvrability, and lesser infrastructure requirements. This paper presents SoloRider, a conceptual autonomous self- balancing electric two-wheeler de- signed for sustainable …

Optimization of Process Parameters for Isopropylation of Toluene over Modified Zeolite using Response Surface Methodology
Abstract: Vapor-phase isopropylation of toluene with isopropanol has been investigated in a fixed-bed flow reactor under atmospheric pressure using N2 carrier gas over Cerium modified 13X zeolite catalyst. The main product of this alkylation reaction was p-cymene followed by meta-isomer, while ortho-cymene was negligibly formed. Response surface methodology was used to study the combined effects of temperature, reactant molar ratio and space time on the conversion of toluene and selectivity of …

Analogous Electrical Modelling of Squeeze Film Damping in MEMS Accelerometers
Abstract: Most of the MEMS (microelectromechanical systems) structures employ parallel plates or beams. A very thin film of air or some other gas in between their suspended structure and fixed substrate is trapped in between these plates. This results in squeeze film damping. Though, FEM (Finite element method) analysis is the most widely used method for studying the effects of the phenomenon, it becomes quite cumbersome and time consuming while analyzing …

Building Behaviour on Sloping Ground With & Without Diaphragm: Earthquake Zone-IV
Abstract: The period 1996 to 2015, 7,056 disasters recorded worldwide. 1.35 million People killed by natural hazards over the past 20 years, more than half died in earthquakes. The poorest nations paid the highest price in terms of the numbers killed per disaster and per 1,300,000 populations. Earthquake load is major effect on buildings especially on sloping grounds. Earthquake zone-IV is twice times more dangerous compare with zone-III. In the present …

Design and Analysis of Different Welding Joints
Abstract: Two parts linked together by the use of localised heat or fusion is called a weld; they join together either with or without the use of pressure or filler material application. Necessary heat required is obtained by burning of gas or by using an electric arc. The word joint and weld are different, weld means joining of two metals by heat and joint means a point where two parts are …
