Designing Physical Unclonable Functions From Optically Active Materials

open access: yesAdvanced Materials, EarlyView.
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

open access: yesAdvanced Materials, EarlyView.
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 ...

Covalent Surface Modification of Hydrophobic Alkoxides on Ti3C2Tx MXene Nanosheets Toward Amphiphilic and Electrically Conductive Inks

open access: yesAdvanced Materials, EarlyView.
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 ...
