Advanced Functional Materials, EarlyView.This review explores functional and responsive materials for triboelectric nanogenerators (TENGs) in sustainable smart agriculture. It examines how particulate contamination and dirt affect charge transfer and efficiency. Environmental challenges and strategies to enhance durability and responsiveness are outlined, including active functional layers ...

3D‐Printed Soft Magnetoactive Origami Actuators
Advanced Functional Materials, EarlyView.Soft magnetoactive films are 3D‐printed using ink with up to 75 wt.% ferromagnetic particles and dual UV/heat curing, then integrated with various origami structures. The films are flexible, magnetically responsive, and programmable, enabling flexible integration with origami without hindering shape‐changeability.

Microneedle‐Based Biofertilizer Delivery Improves Plant Growth Through Microbiome Engineering
Advanced Functional Materials, EarlyView.This figure shows how microneedles are used to deliver biofertilizers to enhance plant growth through microbial migration, metabolic reprogramming, and changes in plant endogenous microbiome. Abstract This study presents a microneedle‐based system for the delivery of rhizospheric biofertilizers into plant tissues to enhance growth.

THE DECLINE (AND REVIVAL?) OF BLACK FARMERS AND RURAL LANDOWNERS: A REVIEW OF THE RESEARCH LITERATURE [PDF]
African-Americans as a group went from owning almost no land in the United States after the Civil War to peaking at 15 million acres by 1920. In that year, 14% of all US farmers were black. Of these 926,000 black farmers, all but 10,000 were in the South.
