					<description><![CDATA[Estonian researchers have revived and modernized nitric acid oxidation of kukersite kerogen, achieving 30 percent dicarboxylic acid yields in just 30 to 40 minutes at 130 to 140 degrees Celsius and 10 to 15 bar, laying the experimental foundation for the Kerox process.]]></description>
