Supercapacitors have emerged as a promising energy storage technology, offering high power density, fast charging and discharging rates, and long cycling life. They have the potential to revolutionize ...

Carbon fibers were successfully fabricated via the electrospinning technique, followed by stabilizing and carbonizing electrospun PAN fibers. A wide range of analytical techniques such as scanning ...

Hydrothermal carbonization of lignocellulosic biomass—the most abundant renewable feedstock—is a promising method for the production of carbon materials with negative carbon emissions. This method has ...

The carbide-based carbon-to-acetylene (C 2 H 2) process is a simple pathway to convert various sources of carbon into acetylene and carbon monoxide directly. However, the current industrial process ...

Carbon fibers consist of thin filaments (5–10 micrometers in diameter) made of long chains of carbon atoms arranged in a polycrystalline structure. These fibers contain 92–100 wt% anisotropic carbon ...

A new technique can produce cement using waste from demolished buildings, which researchers say could save billions of tonnes of carbon by 2050. “We have definitely proved that cement can be recycled ...
