Abstract: A radiation detector (100) includes an insulating substrate (110), which includes a material that undergoes a change in an electrical property when subjected to ionizing radiation. A conductive film (112) is disposed in relation to a surface of the substrate. The conductive film (112) has a resistance that is a function of a state of the electrical property.

Abstract: A DOPA-Gelatin is disclosed in which the monophenolic group of tyrosine, a prominent amino acid in porcine gelatin, is converted into a catechol group using an enzyme-based DOPA modification technique. The resulting DOPA-Gelatin has been discovered to exhibit good mechanical strength and adhesion. Moreover, in vitro studies show that DOPA-Gelatin has no cytotoxicity with HDF and HaCaT cells, two cells typically involved in the skin wound healing process. Further RT-PCR and angiogenesis investigation showed that DOPA-Gelatin can promote the expression of wound-related genes and facilitate neovascularization. In a full-thickness dorsal defect model in mice, DOPA-Gelatin treated groups decreased the wound closure time and enhanced hair follicle growth. These results demonstrate that the DOPA-Gelatin hydrogel compositions disclosed herein are an effective functional biomaterial that can potentiate the wound healing process.

The backward microwave phase modulation signal is extracted by photoelectric converting the backward optical intensity modulation signal, a round trip timing is extracted by demodulating the backward microwave phase modulation signal, and transmission delay is determined from a difference between the timing and the round trip timing.
