Irradiation (UV/Vis λ > 290 nm) under nitrogen and oxygen atmosphere significantly affected the structure of dissolved humic material (DHM). Photobleaching of the DHM solution occurred essentially under O2 atmosphere in conjunction with a decrease i

During industral coking some coals generate pressures in coke ovens that are too high which leads to troubles in operation and shortens coke oven life. Conventional coal testing methods are not capable to fully eliminate dangerous coals from processi
