Surfactant‐Enhanced Electrospun Nanofiber Filters for Efficient Viral and Bacterial Inactivation

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 13, April 5, 2026.
In this work, electrospun polyacrylonitrile (PAN) nanofibrous filters functionalized with surfactants (CTAB, CPC, and SDS) were developed for air filtration applications. The PAN nanofiber mats enable efficient particulate matter capture while simultaneously providing antimicrobial and antiviral activity against bacteria (E. coli and S.

Interface‐Aware Design of Biocatalysis

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 7, 1 April 2026.
Interfaces impact biocatalysis scalability. We reframe gas–liquid, liquid–liquid, and solid–liquid boundaries as design variables, specific interfacial area and renewal rate, that govern activation or deactivation. Mechanistic evidence, quantification tools, and reactor/material strategies enable longer lifetimes and higher integrated productivity by ...

The effect of irrigation method on the quality and shelf-life of strawberry fruit in organic production [PDF]

open access: yes, 2003
The irrigation method did not affect either the shelf-life or the quality of fruit. In organic strawberry production grey mould is a major problem. Strawberry varieties differ from each other in disease susceptibility and the quality and shelf-life of ...
