Two methods for cross-selectivity scissor enhancement of porous poly(vinylidene fluoride-hexafluoropropylene) (PVDF-HFP)/carbon black (CB) composite-based resistive sensors are provided.The sensors are tested with acetone and ethanol in the presence of humid air.Cross-selectivity is enhanced using two different methods to modify the basic response
Many insects are able to walk vertically or upside down on both hard and soft surfaces.In beetles such as the ladybird (Coccinella septempunctata), intermolecular forces between tarsal setae on the footpads of the insects make this movement possible.In prior work, adhesion structures made from polydimethylsiloxane (PDMS) that mimic the action of th
The economic crisis triggered Adhesives by the COVID-19 outbreak has severely affected the global economy.The ultimate scale of the recession is yet to be determined, but it is likely to be the most dramatic slump since World War II.The impact of the crisis on the financial sector, especially consumer finance, could almost instantly be observed.The
Abstract Uncrewed aerial vehicles are integral to a smart city framework, but the dynamic environments above and within urban settings are dangerous for autonomous flight.Wind gusts caused by the uneven landscape jeopardize safe and effective aircraft operation.Birds rapidly reject gusts by changing their wing shape, but current gust alleviation me
