Abstract Gas pool coupled activating TIG (GPCA-TIG) welding put forward in-house can dramatically enhance weld penetration of TIG welding through introducing active element oxygen to reverse the Marangoni convection flow in the molten pool.In order to further improve the welding productivity, the normal solid tungsten electrode is replaced by a kin

Timing of installation is an important factor when planning the deployment of ecological enhancements to intertidal coastal and marine infrastructure.Such nature-based solutions (NbS) are increasingly used worldwide, so understanding whether the timing of deployment affects colonisation success is crucial to enhance their success and identify any e

Piezoelectric micro-pumps offer many applications and could provide considerable flow rates in miniature systems.This study parametrically investigates the effects of major parameters, namely the length, width and attack angle of valves, piezoelectric length, and applied voltage.The results show that these parameters significantly weboost splitter
