Influence of geometrical manufacturing tolerances on lithium‐ion battery performance

open access: yesInternational Journal of Energy Research, Volume 46, Issue 15, Page 23824-23838, December 2022., 2022
The influence of electrode coating thickness, calendaring and electrode cutting tolerance on lithium‐ion battery capacity, energy, resistance and voltage relaxation is investigated through a numerical model. Electrode cutting tolerance has the largest affect upon cell performance characteristics, with calendaring tolerance predominantly affecting the ...

Modular Stimuli‐Responsive Valves for Pneumatic Soft Robots

open access: yesAdvanced Intelligent Systems, EarlyView.
Modular stimuli‐responsive valves, based on responsive materials (i.e., liquid crystal elastomers and hydrogels) and mechanical mechanisms, can autonomously regulate airflow in the presence of multiple environmental stimuli, such as light and water.

Sediment supply control on morphodynamic processes in gravel‐bed river widenings

open access: yesEarth Surface Processes and Landforms, Volume 47, Issue 15, Page 3415-3434, December 2022., 2022
Mobile‐bed laboratory experiments combined with two‐dimensional hydrodynamic numerical simulations showed that sediment supply is a key driver of morphodynamic activity in reach‐scale dynamic river widenings. Sediment supply roughly balanced with the channel's transport capacity led to active channel widening and continued patchy sediment relocation ...

Polydopamine‐Assisted Electroless Deposition of Magnetic Functional Coatings for 3D‐Printed Microrobots

open access: yesAdvanced Intelligent Systems, EarlyView.
A polydopamine (PDA)‐assisted electroless deposition method enables the solution‐based conformal coating of 3D‐printed microstructures with superparamagnetic nickel thin films. This multilayer magnetic coating is implemented and demonstrated in three magnetic microrobot archetypes, including arbitrarily shaped active particles, microrollers, and ...

Degradation of Glyphosate to Benign N‐Formyl Glycine Using MOF‐808 Nanocrystals

open access: yesAngewandte Chemie, EarlyView.
A Zr‐based metal–organic framework (MOF‐808) with different crystal sizes and designed defect sites was employed as an efficient heterogeneous catalyst for the complete degradation of glyphosate at room temperature. The degradation mechanism produces N‐formyl glycine and hydroxymethyl‐phosphonate. Abstract Glyphosate (N‐phosphonomethyl glycine, GPh) is
