In this work, Cyt c was immobilized on a platform, which has been designed by a nanocomposite containing PAN and cMWCNTs on the surface of GC electrode.

Abstract In the present world most of the objects area unit processed and most of them also created online. So the rapid growth in technology has led to the decrease in manual work and is creating most of the objects in various industries of machine-driven. One such automation requirement is found in the chemical industry … Read more

Humans have been surviving off  the resources of the Earth since creation, we are continuously thriving off all our resources without replacing them. One day all these resources will run out and we will have to seek refuge on other sustainable environments that will be able to provide us with nourishment and sustainable resources, this … Read more

Abstract Enzymatic catalysis occurs in almost every cells in organism(Alva & Peyton, 2003)s. Although the activity is invisible in many cases, cellular activities involving energy change proves the existence of catalytic function of enzymes. Using tyrosinase which triggers browning effect in potato with its product melanin, one can visualize  and compare rate of enzyme activity … Read more

The volume of money that is spent on cosmetics and medicines to help ease the process of aging and the changes that come with it is incredibly high1. With recent issues with health organisations, such as NHS, about budgets one of the main aims is to obtain cheaper treatments. An area where there could be … Read more

What’s the scientific name of this organism? Which genus, family, order, class, phylum and kingdom it … Read more

Müllerian Mimicry The South American rainforest contains a big range of different butterflies, even more so then initially suspected. In 1862 when the butterflies were studied for the first time by Henry Bates (1), he quickly realized there were many species with similar appearances. These species of butterflies looked very much alike but were distinctly … Read more

America’s Secret Weapon “We have raised again the question of whether science is good for man, of whether it is good to learn about the world, to try to understand it, to try to control it… Because we are scientists, we must say an unalterable yes” (Bennett-Woods 23). J. Robert Oppenheimer was born on April … Read more

This section focuses on the forensic and research-based uses of polymerase chain reaction (PCR). PCR is a fast and cost-efficient method used extensively in forensic labs and in scientific research worldwide. How is PCR useful in forensics? PCR involves amplifying specific regions of DNA which can then be analysed. In forensic labs, this becomes vital when a sample of … Read more

Health Sciences researcher Carolina Campos Muniz states that from their observation and discovery in 1945 by Italian professor of hygiene Giuseppe Brotzu, cephalosporins have led to remarkable successes against many strains of bacteria. Once he first isolated cephalosporin from a fungus growing in sewage-contaminated seawater on the Italian coast, Brotzu recognized the predecessor of modern … Read more

Genetic Variation in a populace is gotten from a wide arrangement of qualities and alleles. The determination of populaces after some time through changing situations relies on their ability to adjust to moving outside conditions. In some cases the expansion of another allele to a populace makes it more ready to survive; here and there … Read more

Experiment 1: Reconstructing Environment of Deposition using Sedimentary Rocks Sedimentary rock types and structures can be used to reconstruct environments of deposition. In this experiment, you will identify hand samples of sedimentary rocks and use your knowledge of weathering and deposition to determine how the rocks were formed. Materials Hand Lens *Sedimentary Rock Specimens Unknown … Read more

Lost Amongst the Stars It is known fact that women have had their work overlooked in comparison to that of their male counterparts, especially in older times in which people held onto the foolish assumption that men were simply intellectually superior to women.
