Crater Observing Bioinspired Rolling Articulator (COBRA)

Advanced Intelligent Systems, EarlyView.
Crater Observing Bio‐inspired Rolling Articulator (COBRA) is a modular, snake‐inspired robot that addresses the mobility challenges of extraterrestrial exploration sites such as Shackleton Crater. Incorporating snake‐like gaits and tumbling locomotion, COBRA navigates both uneven surfaces and steep crater walls.

An Intrinsically Conductive Cross‐Conjugated Polymer with a Quinhydrone‐Like Donor–Acceptor Charge‐Transfer Network

Angewandte Chemie, EarlyView.
HOT‐DOT, an intrinsically conductive cross‐conjugated polymer, features a covalently integrated, quinhydrone‐like donor–acceptor network formed through spontaneous air oxidation. This built‐in architecture enables self‐doping, stable polarons, and efficient charge transport without dopants.

Exploring Resistive Switching in Novel Amorphous Phosphate Glasses for Next‐Generation Memory Applications

Advanced Intelligent Systems, EarlyView.
This study explores amorphous phosphate semiconductor glass for resistive random access memory (RRAM) applications. The nanodevices exhibit distinct resistive switching via trap‐assisted tunneling, space‐charge‐limited current, and Ohmic transport.

Translation‐Promoting Effects of RNA Template Overhangs in the Absence of Ribosomes

Angewandte Chemie, EarlyView.
Ribosome‐free translation of an RNA sequence into a peptide sequence can be controlled by the folding of the template strand. Overhang sequences forming a triplex structure with the templating region and the peptidoyl RNA in pH‐dependent manner increase yields up to 40‐fold through entropic effects and mixed anhydride formation, allowing for controlled,

Electropermanent Magnetic Muscles: Power‐Efficient, Low‐Voltage, Compact Magnetic Actuators to Power Wearables and Untethered Robots

Advanced Intelligent Systems, EarlyView.
This work presents compact, low‐voltage actuators based on electropermanent magnetic interactions. The actuators show good overall performance across key metrics and are implemented in wearable devices and untethered robots. Their ability to operate in different configurations and hold positions without energy input highlights their potential for ...

Gyroid Labyrinth of Supertwisted Double Helices in a Liquid Crystal Polymer

Angewandte Chemie, EarlyView.
A side chain liquid crystal (LC) polymethylsiloxane (PMS) forms an unusual four‐network gyroid (4NG) structure. In each of the two chiral subspaces, separated by the gyroid minimum surface, there are two networks of aromatic moieties instead of one. These wind around the central polysiloxane bundle, forming a double helix.
