Biochar is the solid residue that is recovered after the thermal cracking of biomasses in an
oxygen-free atmosphere. Biochar has been used for many years as a soil amendment and …

Humidity sensors are widespread in many industrial applications, ranging from
environmental and meteorological monitoring, soil water content determination in …

For a long time, the application of the daily writing carbon ink is mainly reflected on writing
and painting, and rarely used in electronic field. Herein, we analyzed the physical and …

Biochar, a carbon source, obtained from the valorization of biowaste from brewed coffee
(COFF) and chitosan (CTO), were incorporated in different amounts in ZnO particles by co …

Novel electrocatalysts based on zinc oxide (ZnO) and biochars are prepared through a
simple and scalable route and are proposed for the electrocatalytic reduction of CO2 …

Biomasses are emerging as alternatives to traditional synthetic carbon nanostructures to
produce greener, carbon based, sensing platforms. More recently, biochar, a porous …

Coffee is currently one of the most prized food commodities. Its production has grown so
much in recent times, however, the waste by-products generated are also huge. It is …

Biochar is a carbonaceous material obtained by controlled pyrolysis of biomass in a low
amount of oxygen. This material has functional chemical groups on its surface, which can …

Hydrochar (HC) samples were prepared from orange peels waste (OPW) via hydrothermal
carbonization (HTC) at different temperatures, from 180 to 300° C. The complete …

In this work, biochar (BC) derived from spent coffee grounds has been incorporated into high
density polyethylene (PE) through melt mixing. The influence of the filler content on the …
