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

Recent advances in technology permit measurement of characteristics of the nerve fibres that make up the optic nerve. One of these is SD-OCT(Fig2)‚ a non contact‚ non-invasive method that enables physicians to obtain in vivo‚ high resolution (upto 5 microns) cross-sectional images of the retina. It is based on principle of low-coherence interferometry(Fig 3). By imaging a 3D cube of data it allows a detailed evaluation of the peripapillary area.
