Epitaxially Integrated Electro‐Optic KNbO3 Thin Films on Silicon

Advanced Materials, EarlyView.
We demonstrate the first epitaxial integration of electro‐optic KNbO3 thin films on silicon using suboxide molecular‐beam epitaxy. Combining adsorption‐controlled molecular‐beam epitaxy, advanced characterization, and phase‐field modeling, we demonstrate phase‐pure crystalline films mirroring bulk crystals with robust Pockels response, enabling future ...

Renewable energy technology adoption among arable crop farmers in Kwara State, Nigeria: attitudes, constraints and potential food-system implications

Frontiers in Sustainable Food Systems
IntroductionRenewable energy technologies (RETs) can support agricultural energy needs, yet their uptake among smallholder farmers remains uneven. This study examined attitudes, adoption stages, socioeconomic correlates, information access and perceived ...

Performance, fruit quality, and shelf life of tomato (Solanum lycopersicum) grown using charred and uncharred eggshells

Frontiers in Sustainable Food Systems
BackgroundDespite its widespread cultivation, challenges persist in producing tomato fruits with high quality and extended shelf life. This study focuses on the potential of eggshells as a sustainable soil amendment.

An Injectable, Self‐Expanding Hemostatic Foam for Field‐Compatible Postpartum Hemorrhage Management

Advanced Science, EarlyView.
Postpartum hemorrhage is the leading cause of maternal death worldwide, yet many treatments are hard to use outside well‐equipped hospitals. This work introduces an easy‐to‐use device that rapidly delivers a degradable foam into the uterus. The foam stops bleeding through pressure and clotting support, offering a practical option for low‐resource ...

Active Oscillations of Elastic Membranes Arising from the Coupling with a Catalytic Reaction

Advanced Science, EarlyView.
Coupling an elastic membrane to a catalytic reaction produces active oscillations that self‐sustain for hours: the membrane cyclically inflates and deflates as the reaction spontaneously activates and deactivates, without external power. Energy release is directly embodied in the oscillation dynamics, opening elasto‐chemical strategies for the physical

Assessment of smallholder rice farmers' adaptation strategies to climate change in Kebbi state, Nigeria

Heliyon
The future of food production in Nigeria where smallholding agriculture is prevalent is threatened by climate change. Despite the threats, Nigeria has no specific plan or policy to combat it. Therefore, understanding how smallholder farmers adjust to the

Rhizodeposition Drives One Third of Belowground Carbon Input in Agroecosystems

Advanced Science, EarlyView.
This study quantifies photosynthesized C allocation in the plant–soil system across six crop types: barley, wheat, maize, rice, legumes and grasses. It reports C partitioning into shoot respiration, shoot‐C, root‐C, net rhizodeposition and root‐derived CO2, providing standardized percentage averages and GPP‐derived absolute values as a robust baseline ...
