Coffee industry produces more than eight million tons of waste coffee grounds (WCG)
annually. These WCG contain caffeine, tannins, and polyphenols and can be of great …

Activated carbon with large surface area, high porosity and low-cost features is widely
applied as the energy storage material for supercapacitors. Activating agent is significant in …

The high-performance activated carbon prepared from low-cost precursors is urgently
needed for supercapacitors. In this paper, a novel activated carbon that has excellent …

Shochu is a major distilled liquor in Japan, and significant shochu waste (approximately one
million metric tons) is discharged every year. Wheat shochu waste was precarbonized at …

A novel ultrasensitive, selective and low cost electrochemical sensor based on a hollow
sphere bismuth oxide doped mesoporous carbon aerogel nanocomposite derived from a …

In this study, the electrochemical performance of the electrode materials based on two
commonly used binders–poly (vinylidene difluoride)(PVDF) and poly (tetrafluoroethylene) …

Coffee is among the most drunk beverages in the world and its consumption produces
massive amounts of waste. Valorization strategies of coffee wastes include production of …

A novel class of powdery carbon aerogels (PCAs) has been developed by the union of
microemulsion polymerization and hypercrosslinking, followed by carbonization. The …

Wasted coffee grounds (WCGs) were activated by a pyrolysis process using KOH, where the
porosity increased with temperature, exhibiting a micropore-dominant structure. WCGs upon …

A spin‐thermoelectric (STE) voltage is generated when a temperature gradient∇ T is
applied to an element having a thin Pt layer coated on a magnetic substance. In this study …
