Upcycling of non-biodegradable plastics by base metal photocatalysis by Li, Chenfei, Kong, Xin Ying, Lyu, Maoping, Tay, Xiu Ting, Đokić, Miloš, Chin, Kek Foo, Yang, Crystal Ting, Lee, Erin Ke Xin, Zhang, Jinfan, Tham, Chun Yuan, Chan, Wei Xin, Lee, Wen Jie, Lim, Teik Thye, Goto, Atsushi, Sullivan, Michael B., Soo, Han Sen

“…In addition, the latest efforts in the photochemical upcycling of plastics near ambient temperatures are mainly restricted to polystyrene. Here, we report a base metal photo-driven upcycling of most conventional plastics such as polystyrene, polypropylene, polyethylene, polyvinyl chloride, and polyvinyl acetate by a tandem carbon–hydrogen bond oxidation/carbon–carbon bond cleavage reaction, with carbon recoveries up to 77% and selective formation of valuable, isolable products including formic, acetic, and benzoic acids. …”

Experimental investigation of pile-supported/floating breakwaters integrated with oscillating-water-column converters by He, Fang

“…There is a need for new types of breakwaters that can effectively and economically be deployed in places where water is deep or bottom foundation is weak. Since wave energy mainly concentrates near the water surface, and exponentially decreases with increasing distance from the water surface, pile-supported breakwaters and floating breakwaters may be good alternatives to traditional breakwaters. …”
