Abstract A convenient and efficient solvent-free, facile, one-pot Front Closure Bras three-component graphene oxide catalysed approach has been described for the synthesis of chromeno-[4,3-b]quinolin-6-one derivatives from 4-hydroxycoumarin with aldehydes and aromatic amines.Graphene oxide (GO) has proved to be a new class of heterogeneous carbocat
An understanding of the survival probability and abundance of endangered species is critical for their effective conservation and management.In this study, long-term capture-mark-recapture data were used to estimate the apparent survival probability and abundance of green turtles Chelonia mydas at Kuroshima Island in the Yaeyama Islands, Japan.A to
Featured observations of high frequency (HF) heating experiments are first introduced; the uniqueness of each observation is presented; the likely cause and physical process of each observed phenomenon instigated by the HF heating are discussed.A special point in the observations, revealed through the ionograms, is the competition between the Langm
Fourier ptychographic microscopy (FPM) emerged as a prominent imaging technique in 2013, attracting significant interest due to its remarkable features such as precise phase retrieval, expansive field of view (FOV), and superior resolution.Over the past decade, FPM has become an essential tool in microscopy, with applications in metrology, scientif
