Molecular aggregations of electron donor and acceptor are significantly important for light absorption, exciton separation, charge transport, which determine the power conversion efficiency (PCE) organic solar cells (OSCs). Herein, hot solution (HS) casting thermal annealing (TA)-dependent aggregation behaviors a new nonfullerene (NFA), C10-IT4F, systematically investigated. Upon TA treatment, ...

Many experimental methods, giving information about the molecular interactions in liquid crystalline mesophases, have been developed [1]. One of the most important ones is the polarized fluorescence experiment, which enables one to obtain the order parameters and (P4} of a dye probe dissolved in a liquid crystalline matrix ("guest-host" system) [2-9], It was shown that under particular con...

Identification and quantitative determination methods of arsenic species in environmental and biological samples are discussed. Isolation followed by molecular spectroscopic determination is necessary for rigorous identification while element-specific detections coupled with separation techniques are the choice for quantitative determination. Analytical figures of merit are given for the method...

BACKGROUND NPC1L1 is the molecular target of the cholesterol lowering drug Ezetimibe and mediates the intestinal absorption of cholesterol. Inhibition or deletion of NPC1L1 reduces intestinal cholesterol absorption, resulting in reduction of plasma cholesterol levels. PRINCIPAL FINDINGS Here we present the 2.8 Å crystal structure of the N-terminal domain (NTD) of NPC1L1 in the absence of chol...

A central unanswered question in phototransduction is how photosensitive molecules, visual pigments, regulate their absorption spectra. In nature, there exist various types of visual pigments that are adapted to diverse photic environments. To elucidate the molecular mechanisms involved in the adaptive selection of these pigments, we have to identify amino acid changes of pigments that are pote...

We have searched for OH absorption against seven pulsars using the Arecibo telescope. In both OH mainlines (at 1665 and 1667 MHz), deep and narrow absorption features were detected toward PSR B1849+00. In addition, we have detected several absorption and emission features against B33.6+0.1, a nearby supernova remnant (SNR). The most interesting result of this study is that a pencil-sharp absorp...
