Summary of "In-situ Integration of ReS2/Ni3S2 p-n Heterostructure for Enhanced Photo-electrocatalytic Performance."

The excellent light absorption, low electron-hole recombination rate and fast reaction kinetics of photogenerated charges are urgently needed for photoelectrochemical (PEC) water splitting. Herein, a novel p-n heterostructure photoelectrode (ReS2/Ni3S2) is constructed via one-step hydrothermal method, which shows the remarkable HER activity under illumination such as the low overpotential of 106 mV at 10 mA cm-2, high IPCE of 10-15% and good stability. High-resolution transmission electron microscope (HRTEM) and X-ray photoelectron spectroscopy (XPS) reveal the intimate interface and strong electron interaction between ReS2 and Ni3S2 which can enhance the light-adsorption and provide the abundant active sites. The transient absorption (TA) spectroscopy and impedance spectroscopy analyses (EIS) demonstrate the prolonged carrier lifetime and fast charge transfer. All of these are responsible for the improvement of reaction kinetics. This work provides a new avenue to explore efficient photo-electrocatalysts for water splitting.

Insertion of viral DNA into host-cell DNA. This includes integration of phage DNA into bacterial DNA; (LYSOGENY); to form a PROPHAGE or integration of retroviral DNA into cellular DNA to form a PROVIRUS.

A technique that labels specific sequences in whole chromosomes by in situ DNA chain elongation or PCR (polymerase chain reaction).

A malignancy arising in uterine cervical epithelium and confined thereto, representing a continuum of histological changes ranging from well-differentiated CIN 1 (formerly, mild dysplasia) to severe dysplasia/carcinoma in situ, CIN 3. The lesion arises at the squamocolumnar cell junction at the transformation zone of the endocervical canal, with a variable tendency to develop invasive epidermoid carcinoma, a tendency that is enhanced by concomitant human papillomaviral infection. (Segen, Dictionary of Modern Medicine, 1992)

The simultaneous identification of all chromosomes from a cell by fluorescence in situ hybridization (IN SITU HYBRIDIZATION, FLUORESCENCE) with chromosome-specific florescent probes that are discerned by their different emission spectra.
