Experimental Research of Wear On Filled PTFE Alloy Bearings ABSTRACT: Because of the lower coefficient of friction and good strength to weight ratio features polymer based composites are frequently used. In this work‚ experimental investigations were conducted on wear behavior of PTFE composite radial bearings filled with 15% glass fiber (GF15)‚ 40 % bronze (B40) and 35% carbon (C35) where bearing loads‚ sliding distances and wear were taken into account. For the fact that pivot pins have their

Abstract: Finding the half-life of Aluminum-28 is the purpose of this lab. The class met at the Radiation Center and exposed small amounts of aluminum to energetic neutrons and watched the samples decay. After creating a table with background count and gross counts of the aluminum remaining at fifteen different one-minute intervals‚ this allowed the net counts per minute at each interval to be found as well. Next a graph of the net cpm verses time was plotted. After each interval was plotted

Chirality of Ethyl-3-hydroxybutanoate Generated from a Biological Pathway Jake Zimny LaSalle University Philadelphia‚ PA 19141 Submitted February 10‚ 2006 Abstract: The reaction being studied is a reduction of a ketone into an alcohol with a chiral center. Because a biological agent‚ bakers ’ yeast‚ is being used to drive this reaction‚ the optical purity that results in the product is so stereo-selective that the major product‚ (+)‚ is formed for 89% of the product. Introduction: This

Sodium borohydride Reduction of Benzil Introduction: The Purpose of this experiment is for the students to learn how to use sodium borohydride to reduce benzil to its secondary alcohol product via reduction reaction. 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
