Novel Manufacturing of Cellulose‐Based Membranes for Energy Storage Devices: Toward a PFAS Free Future

open access: yesAdvanced Sustainable Systems, Volume 9, Issue 12, December 2025.
This work presents a novel, scalable method for manufacturing PFAS‐free cellulose‐based membranes for energy storage devices. By coating kraft paper with cellulose nanofibrils and optimizing barrier and ionic conductivity properties, membranes are achieved that prevent redox molecule crossover while maintaining performance.

Effect of Shear Stress on Anthraquinones Production by Rubia tinctorum Suspension Cultures [PDF]

open access: yesBiotechnology Progress, 2008
Suspension cultures of Rubia tinctorum, an anthraquinones (AQs) producer, were grown both in Erlenmeyer flasks at 100 rpm and in a 1.5 L mechanically stirred tank bioreactor operating at 450 rpm. The effect of hydrodynamic stress on cell viability, biomass, and AQs production was evaluated.

Effect of organic biocolourants on lightfastness and mechanical properties of polylactic acid

open access: yesColoration Technology, Volume 141, Issue 6, Page 921-931, December 2025.
Abstract Most modern colourants are acquired from petroleum‐based sources or mining, which often causes environmental degradation. Consequently, alternative colouring solutions are sought, such as using biocolourants, which are organic colourants from bio‐based sources.

Chemical profiling and characterisation of anthraquinone‐based polyphenols as biocolourants from Cortinarius semisanguineus

open access: yesColoration Technology, Volume 141, Issue 6, Page 855-888, December 2025.
Abstract Anthraquinone dyes are known for their significant colour (brightness of shade in the red, blue and green areas) and light fastness properties compared with other synthetic dyes (such as azo‐based dyes). However, challenging multi‐step synthesis of anthraquinones and limited access to fewer substituents result in insufficient reactivity ...
