Optimized synthesis of Co-Sn sulfides enhances sodium-ion battery stability and capacity, positioning SIBs as a viable alternative to lithium-ion technologies.

Pushing the limits of structured light, applied physicists report a new type of optical vortex beam that not only twists as it travels but also changes in different parts at different rates to create ...

To analyze the materials, the team used Fourier-transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM ... of epoxy adhesives. The CSR structure, composed of a flexible core and a ...

By combining granular activated carbon (GAC) saturated with PFAS and mineralizing agents like sodium or calcium salts, the researchers applied a high voltage to generate temperatures exceeding 3,000 ...

Rather than importing graphite mined from China or Mexico, rice hull ash could provide a higher quality domestic material for making battery electrodes. The process is also more sustainable than ...

and use as a hard carbon anode in sodium-ion battery cells. Coconut shells, as agricultural waste, with their natural porous structure and high carbon content (about 50%), provide an ideal precursor ...
