Membrane Wrapping for High Capacity and Rapidly Switchable Adhesives
Advanced Functional Materials, EarlyView.A membrane‐wrapping mechanism enables high‐capacity, rapidly switchable adhesion by coupling suction, friction, and adhesion. Broadband performance is achieved in dry and underwater conditions, allowing fast, reversible manipulation of objects of diverse sizes and shapes, from delicate eggs and berries to flat, complex, or heavy objects. These outcomes

A first assessment of the interdependency of mesh motion and free surface models in openfoam regarding wave-structure interaction [PDF]
, 2019 Mesh motion is of key importance in assuring adequate CFD modelling of wave- structure interaction problems, such as wave impact on floating offshore wind turbines and seakeeping of ships. Wave forcing often leads to large displacements

Fluid-structure interaction simulation of flow-mediated dilation of a straight arterial conduit [PDF]
, 2019 Introduction Flow-mediated dilation (FMD) is a key non-invasive clinical assessment of endothelial dysfunction, an indicator of early atherosclerosis and cardiovascular diseases. FMD involves the measurement of an artery dilation, e.g.

Theory‐Guided Design of Non‐Precious Single‐Atom Catalyst for Electrocatalytic Chlorine Evolution
Advanced Functional Materials, EarlyView.To overcome the reliance on noble metals for the chlorine evolution reaction (CER), we designed a non‐precious single‐atom catalyst (SAC), NiN3O–O. It achieves a low overpotential of 75 mV, 95.8% Cl2 selectivity, and outperforms commercial dimensionally stable anodes (DSAs).

Monolithic coupling of rigid body motion and the pressure field in foam-extend
, 2017 In this paper a monolithic algorithm for coupling rigid body motion equations and pressure field within a Finite Volume framework is presented. Monolithic coupling enables fewer number of pressure–velocity loops per time–step, thus reducing the required computational time.

Advanced Functional Materials, EarlyView.MAGTWIST: A compact magnetic rotary actuator, enabling smooth, stepless rotation, and on‐demand locking. Inspired by peristalsis, a soft polymer belt generates a traveling‐wave, enabling 270° rotation when heated. Cooling stiffens the belt, locking it in position and enabling it to withstand high loads.
