Roychand et al. show that the leaching of organic compounds from waste coffee grounds hinders the hydration reaction of cement particles, thereby significantly hampering the compressive strength of waste coffee ground-blended concrete; however, pyrolyzing waste coffee grounds at 350 degrees Celsius led to a significant improvement in its material properties, which resulted in a 29.3% enhancement in the compressive strength of the composite concrete blended with coffee biochar.

Tracking changes among Environmental and Politics Twitter users: (A) the proportion of users that were active in each 15-day window; (B) the rate of change in the proportion of active users for both samples. In both plots, the points depict the observed data while the color band with a broken line shows the 99% confidence interval based on a bootstrap sample of the data. The broken vertical line corresponds to April 25, 2022, when the Twitter board accepted Musk’s initial purchase offer, and the heavier broken line corresponds to October 28, 2022, when Musk’s takeover was finalized.
