Abstract: Systems, articles, and methods directed to electrochemical systems (e.g., batteries) and the electrochemical reduction of halogenated compounds are generally described. In certain embodiments, the halogenated compound comprises a haloalkane associated with a conjugated system via at least one alkene linker or alkyne linker.

Abstract: Systems, articles, and methods directed to electrochemical systems (e.g., batteries) and the electrochemical reduction of halogenated compounds are generally described. In certain embodiments, the halogenated compound comprises at least one sulfur pentahalide (e.g., pentafluoride) group associated with a conjugated system.

Abstract: A multi-edge drill bit includes a drill body and a drill tip at one end of the drill body. The drill tip includes two main cutting edges extending to outside and symmetric about a center of the drill body and two crescent grooves symmetric about the center. Each of the crescent grooves intersects with corresponding main cutting edge respectively to divide the main cutting edge into an outer edge, an arc edge, and an inner edge. A transverse edge is formed between the two inner edges and has its middle point forming the core bit. The outer edges intersect with said arc edges to form two symmetric side bits. A ratio of the vertical distance between the core bit and the side bit to drill diameter is 0.02 to 0.03 and a ratio of the transverse edge length to drill diameter is 0.05 to 0.08. The drill bit as described herein provides a stable centering effect during drilling and facilitates continuous stable drilling in round pipe and thin plate applications.

Abstract: An outdoor ice chest includes a cover with two opposed horizontal cover plates connected to each other via a hinge shaft. A first connecting block is provided at each end of the hinge shaft. The ice chest includes second connecting blocks corresponding to the first connecting blocks and fixed on an external wall of the chest body. A vertical guide slot is provided on the second connecting blocks and a guide rib matching the guide slot is provided on the first connecting blocks. When the cover is opened to take out contents of the chest or the chest is moved, this cover does not dislodge or fall off.
