Laser‐Induced Graphene from Waste Almond Shells

open access: yesAdvanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Uprooting Diversity? Peasant Farmers’ Market Engagements and the on-Farm Conservation of Crop Genetic Resources in the Guatemalan Highlands [PDF]

open access: yes
The long-term security of the global food supply is contingent upon the on-farm conservation of crop genetic diversity. Without it, food crops lack the ability to evolve in the face of new pests, emerging plant diseases, and changing environmental ...

Social-ecological resilience in organic and non-organic cocoa farming systems in the Yungas of Bolivia [PDF]

open access: yes, 2013
Cocoa based small scale agriculture is the basic livelihood of most farming families in the region of Alto Beni in the Bolivian Andes. Cocoa cultivation is affected by climate change impacts, soil degradation, pests and plant diseases, and insecure cocoa

Substrate Stress Relaxation Regulates Cell‐Mediated Assembly of Extracellular Matrix

open access: yesAdvanced Functional Materials, EarlyView.
Silicone‐based viscoelastic substrates with tunable stress relaxation reveal how matrix mechanics regulates cellular mechanosensing and cell‐mediated matrix remodelling in the stiff regime. High stress relaxation promotes assembly of fibronectin fibril‐like structures, increased nuclear localization of YAP and formation of β1 integrin‐enriched ...

Photoswitching Conduction in Framework Materials

open access: yesAdvanced Functional Materials, EarlyView.
This mini‐review summarizes recent advances in state‐of‐the‐art proton and electron conduction in framework materials that can be remotely and reversibly switched on and off by light. It discusses the various photoswitching conduction mechanisms and the strategies employed to enhance photoswitched conductivity.

COBRA: Coordinating Organic Plant Breeding Activities for Diversity [PDF]

open access: yes
Organic plant production is currently challenged by several pressure factors. Along with perennial problems such as weed control, climate change is threatening to affect crop production through increasing weather variability.

Diversity as a key concept for organic agriculture [PDF]

open access: yes, 2008
Diversity is a key concept of organic agriculture and is intuitively perceived as having positive, but not always explicit, consequences for the internal functioning of the farm as well as for the impact on environment and farmland nature.
