Herein, we introduce versatile molecular tools that enable specific delivery and visualization of photoswitchable lipids at cellular membranes, namely at the plasma membrane and internal membranes. These molecules were prepared...
Terahertz wave generation through optical rectification of femtosecond laser pulses and its detection in GaSe and GaSe1−xSx crystals with a relatively low (x = 0.04) and high (x = 0.29) content of sulfur was studied. The decrease of terahertz generation and detection efficiency at an increase of sulfur content in GaSe1−xSx was observed. The phase-matching conditions for electro-optical sampling in GaSe and GaSe1−xSx crystals were analyzed. The arising possibility to achieve the narrowing of terahertz detection bandwidth using thicker GaSe crystals was experimentally confirmed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
