Encoding and Encryption via Dual‐Wavelength 3D Digital Light Processing

Angewandte Chemie International Edition, EarlyView.
Multi‐wavelength 3D DLP printing enables information encoding that can be encrypted on demand by applying orthogonal stimuli within a single material to trigger complementary responses. The 405 nm LED of the printer fabricates complex 3D geometries, while the 365 nm LED activates spiropyrans photochromism to program information into the structure ...

Evolutionary, Functional and Mechanistic Characterisation of Microbial Terpene Synthase‐Like Genes From Springtails

Angewandte Chemie International Edition, EarlyView.
A genome analysis revealed the presence of many bacterial‐type terpene synthases in springtails. Four enzymes from Sinella curviseta were functionally characterised, resulting in the isolation of several compounds including sinellene ether, the first diterpene ether identified from a terpene synthase that represents a novel skeleton.
