Tuning mechanical properties of graphene with Stone-Thrower-Wales defects - A molecular dynamics study G. Rajasekaran and Avinash Parashar Department of Mechanical and Industrial Engineering Indian Institute of Technology, Roorkee - 247667, India HIGHLIGHTS ABSTRACT Structural defects which are inevitable during the production, chemical and heat treatment processes can affect the mechanical properties of graphene and also defects can be deliberately introduced in graphene by ion beam irradiation

Substitution and Elimination Reactions Substitution reactions replace a functional group with a new group. These reactions compete with elimination reactions in which a group is eliminated and a π (pi) bond is formed. Substitution reactions occur when a nucleophile is added to an electrophile/substrate. Elimination reactions occur when a base is added to an electrophile/substrate. The electrophile must contain a leaving group to be considered a substrate. Alkyl Halides Alkyl Halides are the common

ABSTRACT We discussed the exciting materials nanotubes in this outline and the study being carried out on our part. We discussed the materials that are suitable for manufacturing, their processing techniques and exotic applications with supported few references. Here this abstract aims to define the basic principle of nanotubes that is their definition, basic chemical and physical properties, their applications, their fabrication process in details and their future prospect. Nanotubes hold the key

molecules In Season 1, Walt’s chemistry lectures at the high school are a brilliant foreshadowing of what is to come in his life. The lectures seem almost humorously obvious that what Walt is preaching about is what is to come. In the episode 101, Walt’s lecture on the first day of school was an introduction to chemistry. He says that it is technically the study of matter, but he prefers to think of it as the “study of change.” This first lecture is setting up the series for change, particularly

Suspended CNTFETs A suspended CNTFET device. Yet another CNTFET device geometry entails suspending the nanotube more than a trench to reduce contact with the substrate and gate oxide. This technique has the benefit of reduced scattering at the CNT-substrate interface, enhancing device overall performance. There are numerous methods used to fabricate suspended CNTFETs, ranging from growing them over trenches using catalyst particles

Molecular Simulations on the Mechanical Response and Failure Behavior of a Defective Graphene: Cases of Stone-Thrower-Wales (5-7-7-5) defects G. Rajasekaran Rajesh Kumar and Avinash Parashar Department of Mechanical and Industrial Engineering Indian Institute of Technology, Roorkee - 247667, India ABSTRACT Structural defects which are inevitable during the production, chemical and heat treatment processes can affect the mechanical properties of graphene and also defects can be deliberately

Moving away from Classical Chemotherapeutics: A Review of Recent Advances in Targeted Chemotherapy As an elegant manipulation of the cell cycle, cancer pathways have demanded significant attention by the world’s researchers. From molecular biology to inorganic chemistry, each field has conducted a variety of studies to elucidate the pathways cancer manipulates in order to develop successful treatments. To this end, chemotherapy emerged as a prominent research field in the early 1960s and is a type

Chirality – Isolation of Limonene from Citrus Fruits Introduction: Terpenes are a large and varied class of hydrocarbons produced by a wide variety of plants. Many essential oils belong to the terpene class. They are made up of two or more five carbon units that are called isoprenes. Limonene is a terpene that can be separated from orange peels almost 100% in the (R)-(+)-limonene form. Other citrus fruits like lemons, grapefruits, limes, and tangerines contain the compound as well. The

Graphene is a hexagonal two-dimensional (2D) monolayer of honeycomb lattice packed carbon structure that was discovered and successfully isolated from bulk graphite just a few years ago [1]. It is continuously receiving attention from the research community due to its outstanding mechanical, thermal and electrical properties [2]. Due to its fascinating properties, graphene is emerging as a potential candidate material for enormous nano-technological applications such as memory devices [3], nano-sensors

Esomeprazole magnesium trihydrate (Nexium) is a proton pump inhibitor that is used to treat acid reflux which occurs when acid moves back into the esophagus from the stomach. When we swallow food, it goes through the esophagus into the stomach. There is a round muscle at the bottom of the esophagus known as the sphincter that works like a valve. It relaxes when we swallow in order for food to pass through to the stomach. Proton pumps then release acid to help digest the food. The valve is closed
