Modular Critical Element Recycling Platform Using a Nanoporous Additively Manufactured Gyroid

Advanced Engineering Materials, EarlyView.
A modular recycling platform integrates 3D‐printed nanoporous gyroid structures to enable efficient critical element recovery. This system utilizes a hierarchical architecture, combining macroscopic channels with polymerization‐induced nanoscale porosity. By systematically tuning structural wall thickness and resin formulation, the platform achieves an

A Novel Modified Petroresin Particle (MPRP) With Enhanced Oil–Water Selectivity for Cold Production in Heavy Oil Reservoirs

Advanced Functional Materials, EarlyView.
A novel oil–water selective conformance control agent, MPRP, is prepared via hydrophilic grafting and mechanical granulation. MPRP uniformly disperses in water, cohesively expands upon aging, and readily dissolves in the oil phase. During conformance control, it selectively aggregates in water channeling pathways to form effective plugs without ...

Right heart assist for beating heart coronary artery bypass grafting [PDF]

European Journal of Cardio-Thoracic Surgery, 2003
Cardiopulmonary bypass used in conventional coronary artery bypass surgery (cCABG) entails a risk of complications. Consequently, the trend is moving towards off-pump coronary artery bypass (OPCAB). This procedure, however, may lead to haemodynamic instability due to kinking of the right ventricle when the posterior aspect of the heart is exposed.
