A fully deuterated liquid crystal with low absorption in mid-wave infrared (MWIR) is developed. This liquid crystal serves as an important nematic material for future development of low-loss infrared IR liquid crystals and devices. New synthetic approach of perdeuterated 4'-pentylbiphenyl-4-carbonitrile, known as PCB or 5CB, one of the most widely known(More)
A review of gastric brush cytology from 488 patients and esophageal brush cytology from 108 patients over a 7-yr period was undertaken. 80 gastric brushings and 20 esophageal brushings were positive for malignancy.
