Coumarins show promising antimicrobial and antifungal activity, this prompted to us to synthesize new derivatives of coumarins.4-Chloro-2-oxo-2H-chromene-3-carbaldehyde was reacted with substituted aniline and rectified Juice spirit to obtain a new series of Schiff bases of 4-chloro-(3-substituted-phenylimino) -methyl- [2H]-chromene-2-one (3a-i).Th
Is perfectionism associated with academic burnout through repetitive negative thinking?
Academic burnout is prevalent among university students, although understanding of what predicts burnout is limited.This study aimed to test the direct and indirect relationship between two dimensions of perfectionism (Perfectionistic Concerns and Perfectionistic Display Wire Harness Strivings) and the three elements of Academic Burnout (Exhaustion
Integrated highland wildfire, smoke, and haze management in the Upper Indochina region
Fire has long been used in Southeast Asia for the purposes of cooking, protection, and warmth.However, climate change and economic pressure have modified the life of locals, including fire practices in daily life and other fire uses.The land use of forest cover in highland area (mostly deciduous forest) has shifted to cultivation, with the applicat
Optimization of a novel lead-free MASiI3 based perovskite solar cell: A comprehensive study on device performance enhancement
Methylammonium Silicon Iodide (MASiI3), a novel perovskite material, has recently garnered significant attention for its potential to enhance the stability of solar cells.However, MASiI3-based perovskite solar cells (PSCs) have yet to achieve high performance.In this study, we utilized SCAPS-1D device modeling to investigate and optimize the perfor
