Researchers achieve efficient nutrient delivery to crop leaves through nanomaterial surface roughness engineering

Scientists create a pH-controlled oxidation-resistant ferrous foliar fertilizer delivery system that adheres efficiently to hydrophobic leaf surfaces. The innovative technology enhances crop yield and alleviates iron deficiency, offering a viable approach for improving crop nutrition and productivity.

Growing evidence supporting the protein leverage hypothesis

The protein leverage hypothesis proposes that a decrease in protein intake due to modern diets drives increased energy consumption. Research supports this idea, showing how protein appetite interacts with processed foods and life stage changes to increase the risk of obesity.

Researchers achieve high-performance lithium-ion batteries through upcycling of degraded LiCoO2 cathodes

Researchers have developed a solid-phase sintering strategy to convert degraded LiCoO2 cathodes into high-energy-density lithium-ion batteries. The upcycled cathodes exhibit superior cycling performance and rate capability, making this method a promising solution for alleviating resource scarcity and environmental contamination.

A double barrier design proposed to enhance the tunneling electroresistance

Researchers proposed a double barrier structure to enhance tunneling electroresistance in ferroelectric tunnel junctions, achieving a TER ratio of 2.210×10^8% in DB-FTJs, outperforming single barrier designs by three orders of magnitude. The design enables multiple resistance states through controlled polarization of individual barriers.

Unveiling the toll of fossil fuel combustion on children's health and subsequent human capital loss

A new review explores the effects of air pollution and climate change on children's developmental health, leading to human capital losses. The study highlights three dimensions: health, cognitive ability, and socio-emotional ability, emphasizing the need for a comprehensive evaluation of these impacts.
