Identification (RFID) Radio frequency identification (RFID) is an automated data collection technology. It uses radio frequency waves to transfer between a Reader and an RFID Tag. RFID is a technology that incorporates the use of electromagnetic or electrostatic coupling in the radio frequency (RF) portion of the electromagnetic spectrum to uniquely identify object. The advantage of RFID is that it does not require direct contact or line-of sight scanning; it can scan objects while moving that…

I.1- INTRODUCTION: Conformational analysis is the study of the energy change, a molecule undergoes, as it rotates about one or more single bonds. The conformations of a molecule are those arrangements in space of the atoms which are not superimposeable upon each other. The basic idea behind conformational analysis is that molecules will have certain physical and chemical and thermodynamic properties that are dependent on the preferred conformations. in the modern chemistry, where it can…

Jessica Vandeventer 16 March 16 Static Electricity or Electrostatics Purpose/Question- The purpose of this experiment it to explore static electricity and to explore how charges effect one another. Hypothesis– Any like charges will repel each other and any unalike charges will be attracted to each other. Data Tables/ Graphs – Charging Material Pepper Salt Paper Aluminum Styrofoam Uncharged Nothing Nothing Nothing Nothing Nothing Cotton Nothing Nothing Stuck to ruler Stuck to ruler Nothing Fur…

was 7.21. This is a successful titration because in a strong acid and strong base titration, the equivalence point should be ~7. Since HCl fully dissociates into H_3 O^+ and 〖Cl〗^- and NaOH fully dissociates into 〖Na〗^+ and 〖OH〗^-, by forces of electrostatic attraction, the H_3 O^+ and 〖OH〗^- will combine to produce H_2 O and 〖Na〗^+ and 〖Cl〗^- will combine to produce NaCl. At the equivalence point, it is found that 〖[H〗_3 O^+] = 〖[OH〗^-]. Since both molecules fully dissociate, at the equivalence…

About the size of a large fist, heart is made up of cardiac muscle, myocardium, with skeletal muscle-like striations. It has two upper atria & two lower ventricles separated vertically by septum, and four main valves with which the blood makes its directional flow into and out of the heart. Deoxygentated blood with which the blood flows into and out of the organ. Deoxygenated blood enters through the venae cava fills the right atrium (RA) and right ventricle (RV) through the tricuspid valve.…

In this paper, how the sun produces light and heat energy will be discussed. The sun is the most major source of energy and if the sun was not there then Earth and all of its environments would not be able to survive. The sun is mostly hydrogen and produces energy through nuclear reactions. The reactions are specifically nuclear fusions. This is because of hydrogen atoms becoming helium atoms. Heat, Light, and the Sun It always feels good to go outside when there is just the right amount of…

ELECTROCHEMICAL SUPERCAPACITOR – APPLICATION AND GLOBAL DEMAND ABSTRACT: The steep increase in the energy utilization leads us to search for a perfect alternative that can replace the conventional source and introduces a new-generation capacitors called supercapacitors with incredible storage capacity. Much research and investment have been carried out in this impressive technology. It is same as that of the normal capacitor the only thing is it utilizes higher surface area electrode and…

Cell penetrating peptides are proteins or peptides that typically consist of 5-30 amino acids. These peptides are unique in that they are able to cross cell membranes and other barriers throughout the body such as the blood brain barrier, intestinal and nasal mucosa, and even skin. Using CPPs, scientists are now able to explore their potential as a means of transporting cargo into cells and across bio barriers. With their ease of preparation and generally nontoxic nature, CPPs have gained a…

Silver nanoparticles have unique antimicrobial properties. They have a variety of applications: diagnostics, wound healing, pharmaceuticals, etc. These nanoparticles destroy bacterial cells walls and interrupt membrane integrity by their electrostatic attraction to the negatively charged bacterial cell walls [10]. Metal nanoparticles are usually synthesized by chemical techniques which is costly and highly toxic. Currently, there is a growing demand for alternative methods that would limit the…

12(B). The efficiency of photodegradation of aqueous CR was found to be higher in the acidic medium particularly at pH 4 (~99.7%) because Co/Ti LDH surface was highly positive at this pH, indicated by the zeta potential results, creating strong electrostatic interaction with the negatively charged CR ions. At pH > pHzpc, the LDH surface is negatively charged, repelling the dye anions…
