Preventing Lignin Condensation to Facilitate Aromatic Monomer Production

Lignin is the most abundant aromatic polymer in nature and as such is an attractive source of aromatic molecules. Efficient lignin utilization will also likely play a key role in the economic success and sustainability of biomass valorization schemes. Howe ...

Highly Selective Oxidation and Depolymerization of α,γ-Diol Protected Lignin

Jeremy Luterbacher, Jean Thierry C Behaghel de Bueren, Wu Lan

Lignin oxidation offers a potential sustainable pathway to oxygenated aromatic molecules. However, current methods that use real lignin tend to have low selectivity and a yield that is limited by lignin degradation during its extraction. We developed stoic ...

Open-Shell Nonbenzenoid Nanographenes Containing Two Pairs of Pentagonal and Heptagonal Rings

Alberto Fabrizio, Daniele Passerone

Nonbenzenoid carbocyclic rings are postulated to serve as important structural elements toward tuning the chemical and electronic properties of extended polycyclic aromatic hydrocarbons (PAHs, or namely nanographenes), necessitating a rational and atomical ...

Optimization of Lignin Extraction from Pine Wood for Fast Pyrolysis by Using γ-valerolactone-Based Binary Solvent System

Jeremy Luterbacher, Allen Puente-Urbina

Fast pyrolysis of lignin is a promising method to produce aromatic chemicals and fuels. Lignin structure and pyrolysis conditions determine the liquid yield and product selectivity. Extraction of pine wood using γ-valerolactone (GVL) mixed with water in th ...

Dissolved Organic Matter and Associated Trace Metal Dynamics from River to Lake, Under Ice-Covered and Ice-Free Conditions

Natacha Tofield-Pasche, Hannah Elisa Chmiel

The present study investigates the changes in dissolved organic matter (DOM) composition and its influences on trace metal dispersion from the Shuya River (SR) in the Petrozavodsk Bay of Lake Onega during ice covered and ice-free periods. Humic substances ...

Film Morphology Effect on VOC Sensor Performance Fabricated by Drop-On-Demand Inkjet-Printing

Jürgen Brugger, Thomas Maeder, Mohammadmahdi Kiaee

This paper presents a sensor for detecting volatile organic compounds with an inkjet-printed composite. The sensing material is composed of polystyrene (35 kg/mol molecular weight) and a high structure carbon black, Ketjenblack EC-600JD. We used a dual-sol ...

Ultrafast nuclear dynamics of the acetylene cation C2H2+ and its impact on the infrared probe pulse induced C-H bond breaking efficiency

Ursula Röthlisberger, Swarnendu Bhattacharyya

The ultrafast nuclear dynamics of the acetylene cation C2H2+ following photoionization of the neutral molecule is investigated using an extreme-ultraviolet pump/infrared probe setup. The observed modulation of the C2H+ fragment ion yield with pump-probe de ...

Mitigation of Secondary Organic Aerosol Formation from Log Wood Burning Emissions by Catalytic Removal of Aromatic Hydrocarbons

Davide Ferri, Oliver Kröcher

Log wood burning is a significant source of volatile organic compounds including aromatic hydrocarbons (ArHC). ArHC are harmful, are reactive in the ambient atmosphere, and are important secondary organic aerosol (SOA) precursors. Consequently, SOA represe ...

Gas shale water imbibition tests with controlled suction technique

Lyesse Laloui, Alessio Ferrari, Alberto Minardi

Water loss during flowback operations represents one of the main challenges related to the use of hydraulic stimulation to exploit shale gas resources. About 20% of the injected fracturing fluids are usually recovered after stimulation. Fluid imbibition is ...
