Perylene-imide derivatives are industrially important pigments that exhibit a variety of shades from red via maroon to black. In the present investigation, we have synthesized novel perylene-imide derivatives with pyridyl rings in an attempt to apply them for H2 gas sensors based upon proton acceptors. The two N atoms of the pyridyl rings which work as proton acceptors are found to remain unbon...

We report the discovery and characterization of two small transiting planets orbiting bright M3.0V star TOI-1468 (LSPM J0106+1913), whose transit signals were detected in photometric time series three sectors TESS mission. confirm planetary nature both them using precise radial velocity measurements from CARMENES MAROON-X spectrographs, supplement with ground-based photometry. A joint analysis ...

BACKGROUND High blood pressure (BP) is now an important public health problem in non-industrialised countries. The limited evidence suggests ethnic inequalities in BP in adults in some non-industrialised countries. However, it is unclear whether these ethnic inequalities in BP patterns in adults reflect on adolescents. Hence, we assessed ethnic differences in BP, and the association of BP with ...

A star's obliquity with respect to its planetary system can provide us insight into the system's formation and evolution, as well hinting at presence of additional objects in system. However, M dwarfs, which are most promising targets for atmospheric follow-up, underrepresented terms characterization surveys due challenges associated making precise measurements. In this paper, we use extreme-pr...
