Nanoparticles are defined as particulate materials with at least one dimension of less than 100 nanometers (nm), even the particles could be zero dimension in the case of quantum dots (Bar et al., 2009). Metal nanoparticles have been of great interest due to their distinctive features such as catalytic, optical, magnetic and electrical properties (Rassaei et al., 2008). Nanoparticles present a high surface area to volume ratio with decrease in the size of the particles. Specific surface area
The topic I’m speaking on is Periwinkle and Lemon Grass. Periwinkle was first found in Madagascar where the calid climates are located. It is known to treat many things. The main thing it is used for is leukemia and Hodgkin’s disease. Lemon Grass is also found in calid climate such as Thailand and China. Lemon grass is known to treat breast cancer. It is also known to treat many other things such as colds, and coughs. Periwinkle is a biennial, tracheophyte herbaceous plant in the dogbane family that
1. Introduction Most people know about antioxidants and belive in them as preventers against cell damage, which in the most severe case can cause cancer. Almost all nutritions contain a certain amount of antioxidant – both chemical and/or biological. To measure the activity and amount of the antioxidants present in a sample, some distinctive but easy assays have been established. This paper will give a short overview of the ORAC (oxygen radical absorbance cacpacity) assay and compare it with
Manihot esculenta), as well as the castor oil plant (Ricinus communis), are of greatest economic importance. Latex bearing plants are found in some 20 botanical families. The most prominent families include Sapotaceae, Moraceae, Compositae, Apocynaceae, Asclepiadaceae, and Euphorbiaceae. In total there are about 18,000 species of latex-producing plants. Yet, only a few species are currently exploited. Commercially useful rubber-producing species include Hevea benthamiana (Para rubber), Hevea
Background of the Study Systematics and taxonomy involves identifying and resolving relationships among species. But with species today being more taxonomically complex, integrating molecular technology as an alternative tool in species identification has helped systematic s gain new perspective in evolutionary studies .Taxonomy has always been the forefront in the study of life and forever will be (Wheeler 2004). And with the increase in the development within the field of molecular biology and
