Carbon Nanotube as a Material for Casual Wear - Is It Possible
Nanotechnology, in essence, implies working with tiny machines. The 20th century is stated to be the century of computers and IT. Information technology has left its indelible mark on almost fields. If the apparent promises are an indication then the coming century might well prove to be the century of Nanomachines and nanotechnology.

Synthetic studies towards the marine natural product cylindrospermopsin; the causative agent in freshwater toxic blooms
This is regrettable given that Cylindrospermopsin is increasing in importance and bioaccumulation has significant impacts to human and ecological health risks (Humpage 2008). With no further research, synthetic risk assessments are roughly certain undervaluing the general risks of toxin-containing blooms.The study narrows down to effects of cylindrospermopsin in mammalian species, or their end organs and cells. It expands to toxicity model in order to show cylindrospermopsin impacts to

The use of free radicals in the treatment of disease
Free radicals have the ability to damage cells. Respiration and the immune system reaction to the infection are the ways which lead to generation of free radicals in the body. Environment factors, such as food, pollutants and drugs that are used, also contribute to the formation of radicals. Once produced, radicals damage lipids, proteins, nucleic acids and other tissue macromolecules. They also have been proven to play a major role in aging and lead to a series of diseases, including

Electroanalytical Technique (Voltammetric techniques) critical review
However, electroanalytical methods such as voltammetry become vital when samples being analysed contain a single physiologically active component such as the active ingredient in a particular drug.Electroanalytical methods offer advantages such as simple handling of the procedures, high sensitivity, better accuracy and faster speed relative to separation techniques – chromatography and electrophoresis. They also utilise cheaper instrumentation and low cost chemicals. Two electroanalytical

Literature Search/Review Assignment on The role of excipients in tablets
In this regard, an individual need to be always alert for the changes that are minor which may occur in the excipients that are referred to as structure forming within the dosage forms that are semisolid.Other researchers, in an independent study, noted that besides transporting active drug to the respective sites in the body, excipients are used in the process of manufacturing. In regard to this, they aid in stopping the tablet from being given out earlier in the process of assimilation.6 This

Phosphorus speciation in plants
The Phosphorous cycle through which the element is formed will also be discussed in detail using representations. This paper also explores the speciation and fate of phosphorus in the natural environment, particularly in plant’s internal transport.The natural abundance of phosphorus in the Earth’s crust is about 0.12% (Valsami-Jones, 2004). Most of this phosphorus is in the form of minerals like the phosphorites, vivianite, apatite, and wavellite. Among these mineral sources, the apatites,

Phosphorus speciation in plants
Phosphorus deposits can be found in apatite, bird droppings, and fossilised bones. It is gradually released through weathering and erosion as a phosphate ion, which is a water soluble form of phosphorus. Plants absorb phosphorus from soils either in the form of hydrogen phosphate (HPO22-) at pH above 7 or as dihydrogen phosphate (H2PO4-) at pH below 7 (Enger, Ross, & Bailey, 2007). Once absorbed by plants, phosphates are incorporated into biomolecules such, as adenosine triphosphate (ATP),

Determination of Mercury content in Canned Tuna brands using Inductively Coupled Plasma Mass Spectrometry (ICP-MS) and use Isotope ratio to pinpoint where mercury is coming from.
Furthermore, such analysis helps in understanding the biogeochemical cycling of mercury compounds. As a result, enormous and concerted efforts have been made in developing reliable methods for mercury determination and speciation analysis in biological and fish samples. This review articulates with emphasis special attention to clean sample preparation, good storage sample procedures and performance of the different techniques (Lee et al).Mass spectrometry (MS) can be considered as one of the

Insertion of unsaturated species into M-C bonds in cyclometallated complexes from CH activation with the help of MCp* complexes
The important examples include the following:Thagathar explains that Heck reactions do not involve organometals as substrates and hence may not be considered as cross coupling reactions, but its alkyne version, especially the Sonogashira reaction which involves the use of catalytic amounts of CuI salts is usually deemed as cross coupling reaction. The most common catalyses for cross coupling reactions include Ni(O) and Pd(O)( Thagathar 2006).The coupling of aryl halides with arylboronic acids,
