Interface Formation during Collision Welding of Aluminum

Metals, 2020
Collision welding is a high-speed joining technology based on the plastic deformation of at least one of the joining partners. During the process, several phenomena like the formation of a so-called jet and a cloud of particles occur and enable bond ...

Effects of process parameters on mechanical performance and interfacial morphology of electromagnetic pulse welded joints between aluminum and galvanized steel

Journal of Materials Research and Technology, 2021
Magnetic pulse welding (MPW) exhibits an enormous advantage on welded joints of dissimilar metals. Various process parameters (discharge energy and standoff distance) were considered to weld aluminum alloys and galvanized steels by MPW.

Exploiting Device Deformability for Fluid and Particle Manipulation

Small, EarlyView.
Deformable devices enable fluid and particle manipulation modes that are inaccessible to rigid platforms. This review examines soft materials and architectures that translate controlled deformation into microscale fluid operations such as pumping, valving, mixing, and particle handling.

Synergizing Polysulfide Trapping and Fast Ion Kinetics Enabled by Poly(Acrylamide‐co‐Lithium Acrylate) Aqueous Binder for High‐Sulfur‐Loading Lithium–Sulfur Batteries

Small, EarlyView.
A water‐soluble AmLA binder anchors lithium polysulfides and reinforces sulfur cathodes by combining amide and lithium acrylate functional groups. The dual‐function network retards polysulfide dissolution in operando and preserves electrode integrity under large volume changes.

Highly integrated, alignment healing, and full‐recyclable multifunctional flexible devices based on dynamic covalent bonds

Smart Molecules, EarlyView.
This study addresses stability, repair, and recycling in flexible devices using polymers with identical dynamic bonds but incompatible backbones. This enables robust integration, precise self‐healing, and full recyclability. We demonstrate optoelectronic sensors that, after damage, magnetically self‐assemble and heal upon heating.
