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

Biomass, 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 ...

The discovery of new deep-sea hydrothermal vent communities in the Southern Ocean and implications for biogeography [PDF]

, 2012
Since the first discovery of deep-sea hydrothermal vents along the Galápagos Rift in 1977, numerous vent sites and endemic faunal assemblages have been found along mid-ocean ridges and back-arc basins at low to mid latitudes.

Speed structure of the mantle under the Dnieper-Donets depression and its surrooudings. Pt. II

Геофизический журнал, 2020
This work is a continuation of the analysis of the velocity structure of the mantle beneath the Dnieper-Donets Basin and its environment, which includes the north of the Ukrainian Shield and the south of the Voronezh crystalline massif (based on the ...

Deep inelastic scattering from quantum fluids [PDF]

, 1976
A simple and general argument is given for the deep inelastic behavior of the dynamic structure function of quantum fluids at zero temperature. The resulting high-energy tail is shown to give a reasonable fit to existing neutron data for liquid 4He.Peer ...

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

Transactions 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.

Deep crustal electromagnetic structure of Bhuj earthquake region (India) and its implications [PDF]

, 2010
The existence of fluids and partial melt in the lower crust of the seismically active Kutch rift basin (on the western continental margin of India) owing to underplating has been proposed in previous geological and geophysical studies. This hypothesis is

Earthquake in central Italy and velocities structure of the mantle

Геофизический 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

Challenges of using an AUV to find and map hydrothermal vent sites in deep and rugged terrains [PDF]

, 2010
In March 2010, the Autosub6000 AUV embarked on a cruise to discover, locate and map hydrothermal vent sites in an active spreading centre, the Cayman trough in the Caribbean sea. The environment provided the challenge of steep and rugged terrain together
