Recent Advances in Lignin Depolymerization Techniques: A Comparative Overview of Traditional and Greener Approaches

open access: yesBiomass, 2022
Due to the increased and excessive consumption of fossil fuels, sustainable alternative energy sources are badly needed to replace fossil fuels. The conversion of biomass into energy and value-added chemicals is one of the most promising potential ...

Three-dimensional P-velocity model of the mantle and seismicity of Fennoscandia.

open access: yesTransactions of the Karelian Research Centre of the Russian Academy of Sciences, 2019
The paper analyzes the three-dimensional P-velocity model of the mantle of North-West Europe (Fennoscandia) in order to isolate the connection of the earth's crustal earthquakes and processes in the mantle.

Earthquake in central Italy and velocities structure of the mantle

open access: yesГеофизический журнал, 2018
A three-dimensional P-velocity model of the European mantle built on the Taylor approximation made it possible to analyze the velocity structure of the mantle under the Mediterranean and, in particular, under Central Italy, to a depth of 2500 km. It is
