The control over chemical reactions is of greatest interest since early times. The four basic well known variables that are capable of controlling chemical reactions are temperature, pressure, concentration and contact time.1 Therefore in 19th and early 20th century’s high temperatures and pressures were employed in order to achieve reasonable production rates in most industrial reaction processes. Unfortunately these harsh conditions were associated with several disadvantages and problems. Because

Abstract: The emissions from two stroke outdoor power equipment, light terrestrial vehicles, and marine vehicles are a significant detriment to air quality, human health, and the environment. Due to the mechanical nature two stroke engines operations, engines running on fuel oil mixtures that have been blended from biologically based oils generate far less Green House Gas emissions than two stroke engines running fuel oil mixtures blended from more traditional petroleum based outdoor power equipment

CHEM 2123 and 2125 – Organic Chemistry Lab I and II GUIDELINES FOR WRITING LAB REPORTS INTRODUCTION Writing reports in organic chemistry lab may differ from the way it’s done in general chemistry. One goal of this course is to introduce you to the record keeping methods used in research labs. Such methods are designed to organize experimental data in a format similar to that required for publication in major scientific journals. Here are some important considerations that apply in research settings

1.Introduction Halogen bonding, XB, is the product of a non-covalent interaction between a halogen X and a negative site B (e.g., Lewis base). The halogen, X, is usually part of an R-X molecule where R can be another halogen, an organic or an inorganic electron-donating-group. Halogen bonding (XB) is in some ways analogous to hydrogen bonding (HB). In the latter, a hydrogen atom is shared between an atom, group or molecule that “donates” and another that “accepts” it.[1-3] In halogen bonding, it
