Designing Physical Unclonable Functions From Optically Active Materials
Assigning unforgeable “fingerprints” to manufactured goods is a key strategy to fight global counterfeiting. Optical physical unclonable functions (PUFs) are chemically generated random patterns of optically active materials serving as unique authenticators.

Suppression of Stacking Faults for Stable Formamidinium‐Rich Perovskite Absorbers
The authors show that the (011)C perovskite planes are prone to stacking faults formation in all leading formamidinium‐rich perovskite compositions. Using ethylene thiourea as a precursor additive, Othman et al. suppress those vulnerable facets, significantly enhancing the absorber's intrinsic stability under various operational conditions.

Metal‐covalent organic frameworks (MCOFs) are novel porous materials that exhibit the advantages of covalent and metal‐organic frameworks. However, it is extremely difficult to resolve their atomic structure and better understand their structure‐properties relation. This work utilizes a synergistic combination of advanced microscopy, spectroscopic, and

Surprisingly, a cell can bind to itself to make a self‐adhesion, which engineered here to improve how cells attach to biomaterials. Nanoprinting are used to make 3D structures smaller than cells–called Self‐Adhesion‐Tunnels (SATs)–around which cells can wrap and bind to themselves.
