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.

Active Biopaste for Coral Reef Restoration
Preserving coral reefs is essential. A conductive, hardening paste for coral attachment and mineral accretion technology is developed, using a bio‐based acrylate soybean oil matrix and graphene nanoplatelets. Corals are attached with and onto the conductive paste, electricity is applied, water electrolysis is induced, and calcium is deposited at the ...

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

Electrically conductive and amphiphilic MXene inks are achieved by surface modification of sodium alkoxides, where surface‐modified MXenes are dispersible both in water and in non‐polar solvents such as toluene. Alkoxide‐functionalized MXenes also show enhanced environmental stability compared to pristine MXene, leading to higher electrical ...
