Life‐Like Ferrous Oxide Microspheres from Kombucha

open access: yesAdvanced Materials Interfaces, EarlyView.
Kombucha bacterial cellulose, sodium alginate, and ferrous nitrate self‐assemble into membrane‐enclosed iron oxide microspheres. These microspheres bud daughter vesicles, sustain 24‐h electrochemical oscillations, and filter theta‐band signals.

Light‐Controlled Localized Delamination and Blistering of Azobenzene‐Containing Polymer Thin Films in an Aqueous Environment

open access: yesAdvanced Materials Interfaces, EarlyView.
When exposed to light of a defined wavelength, the photoisomerization of azobenzene chromophores leads to polymer reorientation, generating stresses that result in solvent‐facilitated localized delamination of the film from the substrate. Additionally, blisters that form spontaneously when exposed to an aqueous environment can be manipulated via ...

Function of the RNA-targeting class 2 type VI CRISPR Cas system of Rhodobacter capsulatus

open access: yesFrontiers in Microbiology
Bacteria use CRISPR Cas systems to defend against invading foreign nucleic acids, e.g., phage genomes, plasmids or mobile genetic elements. Some CRISPR Cas systems were reported to have physiological importance under a variety of abiotic stress ...

Hierarchically Wrinkled Silver Ink as a Platform for Fully Integrated Stretchable Electronic Systems

open access: yesAdvanced Materials Technologies, EarlyView.
Silver Hierarchical Responsive ink (SHRink), a universal approach for the fabrication of highly stretchable interconnects, wirings, and skin‐interfaced electrodes, is realized through low‐cost, scalable spray‐printing and transfer‐printing. The SHRink demonstrates high electrical conductivity (1.2E04 S cm−1) and large stretchability (235% max fracture ...
