Evolution of the iodine cycle and the late stabilization of the Earth’s ozone layer https://www.pnas.org/doi/10.1073/pnas.

If you like the smell of spring roses, the sounds of summer bird song, and the colors of fall foliage, you have the stabilization of the ozone layer to thank for it. Located in the stratosphere, where it shields Earth from harmful ultraviolet radiation, the ozone layer plays a key role in preserving the planet’s biodiversity.

When a spider is spinning its web, its silk starts out as liquid and quickly turns into a solid that is, pound for pound, sturdier than steel. They manage to create these impressive materials at room temperature with biodegradable and environmentally friendly polymers. Materials scientists at Carnegie Mellon are studying these processes to better understand the ways biological systems manipulate polymers, and how we can borrow their techniques to improve industrial plastic processing.

One unique quality of polymers is that their molecules can have different shapes or “architectures,” and these shapes can have a big impact on their material properties and recyclability. Polymer chains can form molecular strings, mesh-like networks, or even closed rings.

Case Western Reserve University researcher advances zinc-sulfur battery technology. Rechargeable lithium-ion batteries power everything from electric vehicles to wearable devices. But new research from Case Western Reserve University suggests that a more sustainable and cost-effective alternative may lie in zinc-based batteries.

In a study published recently in Angewandte Chemie, researchers announced a significant step toward creating high-performance, low-cost zinc-sulfur batteries.

“This research marks a major step forward in the development of safer and more sustainable energy storage solutions,” said Chase Cao, a principal investigator and assistant professor of mechanical and aerospace engineering at Case School of Engineering. “Aqueous zinc-sulfur batteries offer the potential to power a wide range of applications — from renewable energy systems to portable electronics — with reduced environmental impact and reliance on scarce materials.”

A new study uncovers a molecular modification method for converting CO₂ into valuable chemical resources using a platinum surface.

Copper-based (Cu) materials are widely recognized for their efficiency in converting CO₂ into valuable hydrocarbons via the CO₂ reduction reaction (CO₂RR). However, their stability, particularly in acidic environments, needs significant improvement. In contrast, metallic platinum (Pt) demonstrates excellent stability under both acidic and alkaline conditions. However, its high activity in the hydrogen evolution reaction (HER) hinders its effectiveness in CO₂RR applications.

To address these challenges, composite materials incorporating metal-doped molecules offer a promising solution. These modified molecules can be securely retained at the interface, forming a unique structure that enhances the metal interface properties. This configuration not only increases the contact between reactants and active sites but also optimizes the adsorption strength of critical intermediates, ultimately improving catalytic performance.

Researchers at Cornell University have created a sustainable method to extract gold from electronic waste and use it as a catalyst to transform CO₂ into valuable organic materials.

This process provides an eco-friendly alternative to traditional extraction methods, utilizes vast amounts of e-waste, and helps mitigate CO₂ emissions, showcasing a promising avenue for environmental conservation and resource recovery.

DGIST’s triple-layer solid polymer electrolyte battery improves safety, efficiency, and durability, addressing dendrite issues while retaining 87.9% performance after 1,000 cycles. It holds promise for diverse applications, including electric vehicles and energy storage systems.

A research team from DGIST’s Division of Energy & Environmental Technology, led by Principal Researcher Kim Jae-hyun, has developed a lithium metal battery using a “triple-layer solid polymer electrolyte.” This innovation significantly improves fire safety while extending the battery’s lifespan, making it a promising solution for applications in electric vehicles and large-scale energy storage systems.

Conventional solid polymer electrolyte batteries face challenges due to structural limitations that impede optimal contact between electrodes. These limitations fail to address the issue of “dendrites”—tree-like lithium formations that occur during repeated charging and discharging cycles. Dendrites pose a critical safety risk, as their irregular growth can damage battery connections and lead to fires or explosions.

Dust storms on Mars could one day pose dangers to human astronauts, damaging equipment and burying solar panels. New research gets closer to predicting when extreme weather might erupt on the Red Planet.

Today’s weather report on Mars: Windy with a chance of catastrophic dust storms blotting out the sky.

In a new study, planetary scientists at the University of Colorado Boulder have begun to unravel the factors that kick off major dust storms on Mars — weather events that sometimes engulf the entire planet in swirling grit. The team discovered that relatively warm and sunny days may help to trigger them.

The future is full of all-new EVs. Here’s what to expect in the coming years.
