A Fungus-Derived Material Could Serve as an Eco-Friendly Alternative to Concrete

Material & Energy, Material Technology /

One effective way to lessen our environmental impact is by adopting more sustainable construction methods. Cement production alone contributes to 8% of global CO2 emissions—much of it used in making concrete. Solving this issue is challenging, as it demands eco-friendly materials that match concrete’s strength and require minimal upkeep. That’s why researchers are exploring engineered […]

Crystal-Based Cooling Could Prevent Future Devices From Overheating

Material Technology, Tech /

As I write this on a laptop that keeps freezing and refuses to switch between tabs due to the early Indian summer heat, it becomes clear how common overheating issues are. I’m not even running heavy programs or multiple browsers — this old machine just isn’t able to dissipate the heat from its internal components

Substitute For Cement Sand Made From Seawater, Electricity, And CO2

Material & Energy /

This seemingly simple white paste could be key to addressing the global sand shortage while also transforming the cement production process to capture, rather than emit, carbon dioxide. Researchers at Northwestern University have developed this material using seawater, electricity, and CO2. Concrete is the most widely used man-made material worldwide, but its production is also
