The inclusion behaviour of "wheel-and-axle" host compounds
The inclusion behaviour of three "wheel-and-axle" host molecules was investigated. By virtue of their shape and the way in which they pack these host molecules are able to entrap guest molecules into a host-guest array. The host compounds were: 1,1,6,6-tetraphenyl-hexa-2,4-diyne-1,6-diol (HOST1), …

Design, fabrication, and characterization of split axle skateboard trucks
… with existing hardware but also features a split axle geometry which allows the left and right wheels to move independently. In order to determine whether the split axle trucks improved rider comfort, the trucks were tested on a skateboard outfitted with sensors that measure acceleration normal to …
