Rapid Photogelation of Low‐Concentration Polymer Solutions via Photodimerization of o‐Ethylnitrobenzene

open access: yesAdvanced Science, EarlyView.
Upon UV irradiation, flexible and tough hydrogels are formed rapidly (>0.5 s) from dilute (>0.5 wt%) solutions of o‐ethylnitrobenzene–modified PVA. At ∼1.5 wt%, the hydrogels withstand up to 10 MPa compression, remain handleable even after 200‐fold swelling.

Blockchain Enabled Quality Management in Short Food Supply Chains [PDF]

open access: yesProcedia Computer Science, 2022
Food system (re)localisation involves moving food systems back to local areas and a result are the short food supply chains. Food system (re)localisation is occurring to offset the perceived negative impacts of global food systems. Short food supply chains may face challenges in terms of quality set at national and international levels.
