Advanced Science, EarlyView.Dual‐state activation of singlet and triplet excitons is achieved in perylene‐based nanomicelles via donor engineering. By synergistically pairing charge transfer with energy transfer pathways, while concurrently enabling pollutant pre‐enrichment, this strategy establishes spatial coupling between efficient ROS generation and rapid mineralization ...

Bound Water as a Reinforcing Element for Ultra‐Strong Polyacrylamide
Advanced Science, EarlyView.Rather than acting as a conventional plasticizer, bound water serves as a reinforcing element in polyacrylamide by constructing strong PAM–water–PAM hydrogen‐bond networks. This water‐mediated architecture delivers ultra‐high mechanical strength and exceptional flame resistance, redefining the role of water in polymer reinforcement.

Dynamic modeling and simulation of a solar direct steam-generating system
International Journal of Energy Research, 2010 A dynamic model of solar parabolic trough collectors has been developed and solved by explicit Euler's method to predigest partial differential equations to ordinary differentials in this paper. Different working conditions of the collector structure and thermal parameters have been considered in the model. The simulated results are validated using the
