Tough and Skin‐Free Porous Polyelectrolyte Complex Hydrogels via Salt‐Induced Aqueous Phase Separation

open access: yesAdvanced Functional Materials, EarlyView.
Controlling counterion exchange rate during aqueous phase separation enables the formation of skin‐free, homogeneously porous polyelectrolyte complex hydrogels by suppressing kinetically trapped skin layers and macrovoids. The resulting hydrogel networks exhibit exceptional toughness (∼15 MJ·m−3) and enable 3D (bio)printing and post‐functionalization ...

Advancing a food loss and waste bioproduct industry: A critical review of policy approaches for application in an Australian context

open access: yesHeliyon
Food loss and waste (FLW) contains an abundance of nutrient components that can be extracted and converted into valuable bioproducts through biorefining (e.g., pharmaceuticals, cosmetics, nutrients).

Livestock-mediated food waste conversion: Advancing resource efficiency and sustainable agriculture

open access: yesNotulae Botanicae Horti Agrobotanici Cluj-Napoca
Food waste throughout the agri-food supply chain has significant environmental and economic consequences on a global scale. To address this issue, upcycling food waste through livestock is a promising approach that can help achieve sustainability goals.

On the Prevention of Avoidable Food Waste from Domestic Households

open access: yesRecycling, 2018
Unconsumed food impacts on the environment via the wasteful use of resources in its production and via its disposal. Householders would ideally only generate food waste that is not considered edible (unavoidable food waste) and the disposal of edible ...

Photo‐Switchable Molecular Module Programming PET Biodegradation in Aquatic Environments

open access: yesAdvanced Functional Materials, EarlyView.
We address the plastic durability paradox by integrating an itaconic acid–derived pyrrolidone module into polymer backbones. Sunlight in water triggers Norrish Type I ring‐opening and hydrophilization, enabling rapid biodegradation into nontoxic minerals.

Photo‐Degradable Polyester Networks and Multi‐Photon Printed Objects Based on Cyclic Ketene Acetals

open access: yesAdvanced Functional Materials, EarlyView.
The current work introduces a photoreversible polyester network derived from radical ring‐opening polymerization of cyclic ketene acetals. It combines photoreversible cross‐linking with initiator‐free multi‐photon printing. Reversible network formation, tunable mechanical properties, and selective degradation highlight its potential as a versatile ...

Biodegradable 3D‐Printable and Coatable Antifouling Composites for Marine Applications

open access: yesAdvanced Functional Materials, EarlyView.
Marine biofouling damages submerged surfaces and raises greenhouse gas emissions. Biodegradable antifouling biocomposites were developed by hot‐mixing beeswax, Tween 80, and calcium stearate or stearic acid. Adjusting the component ratio enables processing via hot‐pressing, 3D‐printing, or dip‐coating.
