Effect of minor reactive metal additions on fracture toughness of iron: 12-percent nickel alloy at-196 deg and 25 deg C [PDF]
The slow bend precracked Charpy fracture toughness and tensile behavior of arc-melted and hot-rolled Fe-12Ni alloys containing up to 4 atomic percent reactive metal additions were determined at -196 C and 25 C after water quenching from three annealing ...

Advanced Materials Interfaces, EarlyView.This study examines how a PVDF‐like binder affects the argyrodite Li6PS5Cl electrolyte properties. Using an approach that combines bulk and surface characterization with electrochemistry, we found a chemical interaction between Li6PS5Cl and PVDF, resulting in partial chlorine substitution by fluorine and slightly reduced ionic conductivity.

Hydrogel‐Based 3D‐Printable Stretchable Pressure Sensor
Advanced Materials Technologies, EarlyView.We present a carbon‐black‐functionalized double‐network granular hydrogel (DNGH) pressure sensor capable of detecting pressures from 200 Pa, equivalent to a light finger touch, up to 500 kPa. The sensor exhibits signal drifts below 3.5% after 800 cycles and response times around 80 ms. Leveraging this broad sensing range, we 3D print this material into
