TL;DR: In this article, a slow pyrolysis process of cellulose nanofibers from wood, Cladophora algae and bacteria that were subjected to various drying routes was explored, with the aim to produce chars having large surface area and pore volume for dyes adsorption and oil absorption.

TL;DR: In this paper, a combination of analytical and testing techniques was used to characterize the wear performance of automotive brake material and debris collected after brake dynamometer test and after ball-milling of identical semimetallic friction lining.

TL;DR: In this paper, the influence of CaCl2 and urea as possible chemical additives inhibiting coal oxidation process at temperatures between 100 and 300 °C was studied and it was shown that the presence of urea in the coal induces decrease in activation energy of the oxidation process indicating rather catalysing than inhibiting action on coal oxidation.

TL;DR: In this paper, the authors studied coal-chemical additive-oxygen interaction at the temperature 30°C with the aim of identifying inhibitors of coal oxidation process that are able to modify the coal surface in a chemical way.

TL;DR: In this article, the process of oxygen chemisorption on coal in the temperature range ≈150-300 °C was studied under different experimental conditions using TG-DSC apparatus.
