Flexo‐printable glucomannan‐based biofilm
Abstract Biofilms were synthesised from glucomannan and xylan. The ratio of glucomannan: xylan varied from 90:10 (g/g) to 70:30 (g/g). Nanofibrillated cellulose was added to enhance the mechanical properties of the biofilms. In another approach, glucomannan/xylan suspensions were crosslinked with tartaric acid (TA) or citric acid (CA).

Colour appearance descriptors for image browsing and retrieval
In this paper, we focus on the development of whole-scene colour appearance descriptors for classification to be used in browsing applications. The descriptors can classify a whole-scene image into various categories of semantically-based colour ...

Reinventing henna: Enzyme‐catalysed colour release from stabilized Lawsonia inermis L. extracts
The instability and reduced dyeing performance of a cosmetic formulation containing 2‐hydroxy‐1,4‐naphthoquinone (lawsone), derived from Lawsonia inermis L., is demonstrated in comparison to a novel two‐component system. This system comprises one formulation with naturally occurring lawsone precursors and a second containing a specific hydrolase ...
