Treatment of optically active (PrCHBr)2CH2 with Li-Hg or biphenyl-Li gave 46:54 or 59:51, resp., cis- and trans-1,2-dipropylcyclopropane (I). The original (R,R)-configuration at both chiral centers was inverted in the course of the cyclization reaction lea ...
This paper present a polarimetric fiber optics current sensor using a 22.5 degree Faraday rotator and a Faraday rotation mirror. The objective of this sensor is to be low-cost, high accuracy and easy to manufacture ...

The size, shape, and polarization orientation of fatigued areas formed during the suppression of the switchable polarization (P-r(s)) (fatigue) in Ft-FZT-Pt ferroelectric capacitors (FECAPs), were observed by means of atomic force microscopy and by imaging ...
BACKGROUND AND OBJECTIVE: A technique to manufacture a stable, reproducible three-dimensional optical phantom is presented. This phantom reproduces the tissue's optical properties as well as the geometry and, to some extent, the mechanical properties of th ...
Polarized IR spectra of melittin (I) incorporated into macroscopically oriented lipid membranes are reported. From the linear dichroism of the amide I and amide II vibrational bands, the spatial orientation of I helices was detd. as being preferentially pa ...
