Introduction:

Nanobiotechnology serves as an imperative technique in the development of clean, nontoxic, and eco-friendly procedures for the synthesis and congregation of metal NPs having the intrinsic ability to reduce metals by specific metabolic pathways. Silver nanoparticles are particularly interesting nanoscale systems due to the ease with which they can be synthesised and modified chemically. Synthesis of silver nanoparticles has been widely researched due to their interesting size and shape-dependent properties [26]. These novel properties can be tailored by controlling their size, shape, composition, structure and crystallinity. Due to their size features and advantages over available anti-microbial properties, chemical imaging ...

Literature Review

Abstract Innovations and modifications that produce cost reductions and enhance performance have driven the evolution of the classic solid rocket and the liquid bipropellant rocket into hybrid models that integrate the predominant solid and liquid model features into more sensical, more economical fabrications of design. The commercial spacecraft demands for aerospace propulsion have also evolved to include a market for environmentally sustainable hybrid rocket engines that has yet to fully mature to the Technology Readiness Level (TRL). Numerical modeling has been used as a tool to test the feasibility of new solid fuel types. ABS has been considered as ...

Introduction

The conversion of gas into liquid fuels is an innovative technology that is well-known to many people. This technique is so promising and enhancing new options for environmentally friendly manufacturing of fuels and chemicals as well as other natural gases. Looking into the large natural gas and coal reserves and deteriorating petroleum reserves all over the world, it is anticipated to play an important role in the future. Cobalt-based chemical agents are the ideal catalysts for hydrogen synthesis since they have a high FTS functionality, discernment for long-chain paraffin as well as a low process for the water-gas change ...

Introduction

Tension forces act on liquid surfaces, the thread in them is pulled into circular arcs. The pull is referred to as surface tension of the liquid. Surface tension exists uniformly in all directions. The forces affect the shape and motion of liquids that have open surfaces. Tension forces can be understood regarding forces that occur between the molecules. Repulsion occurs in molecules when they are close but attract when they are far from each other. Inside the liquid, molecules are close to each other. Thus, there are slight repulsions. Molecules at the surface of the liquid are some distance ...

Purpose

This experiment sought to determine the value of the surface tension of water and paraffin oil from the downward pull on a horizontal ring fastened to a spring.

Apparatus

The following materials were used in the experiment: Platinum-iridium ring equipped with stirrup (circumference L=4cm)

Spring

Paraffin oil Distilled water Petri dish Weight pan Striker Level Jolly balance with adjustable platform Scale to determine the paraffin oil density Suitable weights Bunsen burner Tweezers Introduction Surface tension refers to the energy required to expand a liquid’s surface area (Ozment, John, and Conrad, 391). Liquid molecules are attracted to one another by adhesive ...
