Reducing sugar

in sourcing as a viable option to control cost and reduce overhead, the following options were examined. Any one or all the below options could be implemented to help meet the required mandate. • Reduce size of current catalogue items, thus reducing facility space. • Better quality control. • Reduction of workforce (in periods of declining sales. • Better control of lead-time, transportation, and warehousing costs. • Cost considerations of current catalogue items. OUTSOURCING-

This two-step reaction reduces aldehydes by hydrides to primary alcohols, and ketones to secondary alcohols. In order for the reaction to occur and to better control the stereochemistry and yield of the product, the metal hydride nucleophile of the reducing agents such as LiH, LiAlH4, or NaBH4 must be carefully chosen. Being that LiAlH4 and NaBH4 will not react with isolated carbon-carbon double bonds nor the double bonds from aromatic rings; the chosen compound can be reduce selectively when the nucleophile

The Effect of Common Bactericidal Agents on Staphylococcus Epidermidis Introduction Staphylococcus epidermidis is a facultative anaerobic bacterium. It is part of the normal human flora and is found on the skin. Colonies of these bacteria can produce a protective slime called a hydrophobic biofilm. Staphylococcus epidermidis is usually not pathogenic unless it enters the human body. One of the most common places for infections are hospitals where people often have weakened immune systems, open

Photocatalysis is the acceleration of a chemical reaction by light. The activity of these catalysts usually depends on their ability to produce pairs of negatively charged electrons and positively charged electron holes (electron-hole pairs) on material surfaces, which is induced by light irradiation. An electron hole is the absence of an electron from the full valence band. Furthermore, as light interacts with matter in the form of energy packets, the photons, it excites an electron consequently

agent in order to use that ketone in a reduction reaction with a specific reducing agent to determine the affect of that reducing agent on the diastereoselectivity of the product. In the first part of this experiment, 4-tert-butylcyclohexanol was reacted with NaOCl, an oxidizing agent, and acetic acid to form 4-tert-butylcyclohexanone. In the second part of this experiment, 4-tert-butylcyclohexanone was reacted with a reducing agent, either NaBH4 in EtOH or Al(OiPr)3 in iPrOH, to form the product 4-tert-butylcyclohexanol

characterized by the prescence of azomethine (>C=N-N=C<15 min). The hydrazones obtained are tested for their DNA cleavage properties and some of them are found to show good chemical nuclease activity in the presence of both oxidizing agent (H2O2) and reducing agent (MPA). Some of them exhibited hydrolytic activity and their antioxidant activity was found to be very low. 2.5. RESULTS AND DISCUSSION Though aryl hydrazones of aryl aldehydes, known as Schiff bases, are well known, the study of any hydrazones

chemical and mechanical exfoliation for graphene synthesis, which are the methods with highest number of experiments done. Chemical exfoliation by reduction. Scientists decided to continue the infamous experiment of Benjamin Brodie by reacting strong reducing agents to graphite. In 2015, Li and Chopra attempted to do the same principle by Brodie. They first convert graphite to a compound known as graphene oxide. This process made the thickness of the substance decrease significantly as the 3-D graphite

LAB 9: REDUCTION OF CARBONYL COMPOUNDS: PREPARATION OF FLUORENOL (Preparative) Introduction The first purpose of this lab was to reduce 9-Fluorenone to 9-Fluorenol using a selective metal hydride reducing agent- Sodium Borohydride (NaBH4) in Methanol solvent and acidification. The second purpose of this lab was to identify the 9-Fluorenol product via melting point and Infrared spectroscopy analysis and characterize the purity. The third purpose of this lab was to define the efficiency of lab technique

suppliers is one of significant decisions related to design and administration of establishments supply base. The description of the successful implication of reduction in the supply bases can be seen in the practise reports. The benefits can be seen by reducing the amount of suppliers. Background In North America, being one of the biggest fleets the Fleet Corporation runs nearly 30000 trucks in operation. More than 25 million customers including municipal, industrial as well as residential customers are

Copper is a metal that has been used by humans essentially since the beginning of existence as it is said to be only the second metal used by man after gold. Therefore, copper production has been an important part of life for thousands or years and still is today. The copper cycle is an important because it provides a basis for how copper can be recovered from various compounds that it exists in during its so-called “life-cycle” . The life cycle of copper conserves this now scarce metal by allowing
