Essays on Phenol

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 ...

Lignin Chemistry

Lignin History Lignin is a plant-derived biopolymer with several applications. It is considered an effective alternative to chemically synthesized plastics that pose serious environmental problems during manufacture and disposal. Lignin is often obtained as a byproduct in paper and pulp manufacture. Lignin has to be dissolved to obtain cellulose from wood. In 1838, Anselme Payen discovered that wood contained cellulose, and oxidizable coatings (later called lignin) that bind the cellulose together (McCarthy and Islam, 2000). This coating material could be removed from wood after acid treatment and washing with an aqueous alkali solution (McCarthy and Islam, 2000). Later, several ...

Identification of the Unknown Microorganisms

Unknown #1 Unknown #2 1. The identification of bacterial strains is a common practice in clinical and medical fields. The ubiquitously present microorganisms can be both, beneficial or harmful to the host they attack or inhabit. Since times, several biochemical characteristics have been identified for many bacteria that commonly are related to humans. These characteristics and morphology have been arranged in a systematic way to identify the targeted unknown microorganism along with ruling out the ones giving negative results for the characteristic tests. This way the search was narrowed down for each of the two unknown microorganisms. The Gram ...

Writing Hypothesis

Question 1: (a). H0: Supplementation of arginine reduce the volume of nitric oxide, a major sign of inflammatory reactions in asthma patients. H1: Supplementation of arginine does not reduce the volume of nitric oxide, a major sign of inflammatory reactions in asthma patients. (b) Sample: Diagnosed asthma patients of age between 19 years and 50 years (c) Data needed: Data on quantity grams of arginine supplementations (AS) and data on volume of nitric oxide (NO), as a sign of inflammatory reactions. Data on confounding variables such as grams of alcohol, and grams of chemical irritants such as phenol. (d) ...
