Understanding social and solidarity economy in emergent communities: Lessons from post-fast track land reform farms in Mazowe, Zimbabwe [PDF]

open access: yes, 2014
This paper deals with the emergent and evolving forms of social organization in Zimbabwe's post-Fast Track Land Reform Programme (FTLRP). It highlights the way in which these institutional formations show the emergence of a social and solidarity economy ...

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.

Electron‐Deficient Linkers Enhance H2O2 Electrosynthesis in Covalent Organic Frameworks

open access: yesAdvanced Functional Materials, EarlyView.
Linker π‐conjugation modulates the electronic state of the Ni–N4 centers and their interaction with the key *OOH intermediate while preserving the primary coordination motif. NiPc‐PTDA delivers an H2O2 selectivity of 92% and a production rate of 34.8 mol gcat−1 h−1, highlighting linker electronic properties as a molecular design parameter for NiPc ...

Social economy

open access: yes, 2015
The criterion 'social economy' describes how forestry and the wood industries relate to society. The emphasis here is on the economic and social aspects of sustainable forest management. Since the last Forest Report in 2005, the importance of these aspects and the complex relationships between them have noticeably increased - for example, the way the ...

Decoupling the Size and Loading Effects in Silver Nanoparticles for Efficient Paired Carbon Dioxide and Formaldehyde Electrolysis

open access: yesAdvanced Functional Materials, EarlyView.
We investigate size‐dependent CO selectivity on Ag nanoparticles, where optimized Ag loading achieves nearly 100% Faradaic Efficiency for CO at −100 mA·cm−2. In situ SERS and XPS reveal the crucial role of optimized loading in catalytic performance. The Ag/C catalyst further exhibits bifunctional activity, enabling efficient electrolysis of CO2 and ...
