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 ...

Abstract

In this experiment, benzene was treated with hydrogen in the presence of Pt/SiO2 as an example that can be applied on industrial operations to show that the most recently modernized methods of neutron total scattering that cover a wide Q-range allow the use of appropriate catalytic chemistry that can be measured on time domain to probe directly on site the hydrogenation of benzene within the catalyst pore. Based on this method, it is possible to study the rates of reaction on length scales that can provide measurements equivalent to the size of an atom or a nanometre. Furthermore, the ...

Abstract

This report highlights the procedure and intent of conducting Line Operation Safety Audit (LOSA) for airline companies. This audit is carried out to evaluate the strengths and weaknesses of safety management systems in airlines. In the light of its findings, airline management could clearly see the scope of improvement in complying with required safety standards and regulations. Flight crews could also judge their performance and improvise their skills to strengthen safety envelope. This report will briefly present the procedure and characteristics of LOSA. The report covers all essential elements of LOSA. Firstly, introduction to LOSA is provided containing it's ...

Introduction:

Transmission electron microscope (TEM) is the type of a microscope that uses a beam of electron rather than visible light to illuminate the specimen. Besides, while light microscope uses glass lens to focus light to the specimen, TEM uses electromagnetic lenses for focusing of the electron beam. TEM has a higher resolving power than the light microscope because the electron beam it uses for illumination has a much lower wavelength than visible light. During the operation of TEM, some electrons passing through the specimen get scattered and disappear from the beam. However, the unscattered electrons reach a fluorescence screen ...

2. The nano carrier needs to remain in suspension in H2O, PBS, human serum, etc. What type of polymer do you need to use to decorate the surface of the nanocarrier to achieve this goal? In order to maintain the nanocarrier in suspension in water, Phosphate-Buffered Saline (PBS), human serum a suitable solution a polymer is needed on its surface. The polymer used needs to accomplish three goals. The polymer needs to decorate the nanocarrier surface to enhance suspension and secondly, to prevent protein absorption. Another characteristic is that the polymer evades the immune system. PLGA poly(lactic-co-)glycolic ...

Abstract

Microscopy is the science of viewing objects that are very minute and can only be viewed by an instrument called a microscope. The science began in the 16th century and has been progressing into viewing specimens at higher resolutions, greater magnifications, and in 3-D. These advancements are in the three sub-branches of microscopy which are scanning-probe, optical, and electron microscopy. The paper analyses the latest advancements in the three fields indicating what the invented microscopes can be used in science.
