Biodegradable poly(α-hydroxyacids) have gained increasing interest in the biomedical field for their use as cell microcarriers thanks to their biodegradability, biocompatibility, tunable mechanical properties/degradation rates and processability. The synthesis of these poly(α-hydroxyacids) can be finely controlled to yield (co)polymers of desired mechanical properties and degradation rates. On ...
The tensile properties of fiber-reinforced composites (FRP) under various factors composite aging were studied by test. test parameters mainly include temperature, salt spray, ultraviolet, rainwater, and stress. results show that the higher faster FRP strength decreases; At same ultraviolet radiation has little effect on BFRP bars. Salt spray rainwater hydrolyze resin surface steel bars expose ...
Ecosystems in alpine mountainous regions are usually more vulnerable and easily be disturbed by environmental change globally. Alpine swamp meadow, a unique grassland type in the eastern Tibetan Plateau which provides important ecosystem services to the upstream and downstream regions of international rivers of Asia even the world, is undergoing severe degradation, which can dramatically alter ...
