Promoting exciton dissociation of covalent organic frameworks via donor-acceptor characteristic modulation for enhanced HO photocatalytic production.

Post-synthetic modification (PSM) offers a promising approach for tailoring the compositional, structural, and electronic properties of covalent organic frameworks (COFs), thereby enhancing their exciton dissociation ability and facilitating charge transfer. The effectiveness of these approaches is largely compromised by the harsh conditions, complexity, and alteration of the original structure. Therefore, developing a facile yet effective PSM for modulating COFs' properties without altering the original geometry and/or structure is a challenge.

Harmony in the Digital Labyrinth: The Pursuit of Psychological Well-Being for Youth in the Digital Age.

Social media offers numerous advantages, yet the dark side of it haunts youth. One of the several potential detrimental aspects appears as social media addiction (SmA), which poses risks to the psychological well-being (PW) of youth. Among university students, excessive social media use can lead to SmA and a subsequent decrease in PW.

Grandiose narcissism, leadership, and workplace deviance: does self-interest always breed toxicity in leadership roles?

Background: Existing literature on leader narcissism reveals conflicting evidence due to the paradoxical nature of narcissistic traits- narcissistic admiration and rivalry. Additionally, a bipolar view of self-interest, rooted in the concept of dual behavior may help in clarifying this paradox. Therefore, the study examines how narcissistic admiration and rivalry affect leader narcissism and workplace deviance, with self-interested behavior acting as a mediating factor.
