Carbohydrate stabilization extends the kinetic limits of chemical polysaccharide depolymerization

Jeremy Luterbacher, Masoud Talebi Amiri, Ydna Marie Questell-Santiago, Raquel Zambrano Varela

Polysaccharide depolymerization is an essential step for valorizing lignocellulosic biomass. In inexpensive systems such as pure water or dilute acid mixtures, carbohydrate monomer degradation rates exceed hemicellulose—and especially cellulose—depolymeriz ...

Efficiency improvement of an all-vanadium redox flow battery by harvesting low-grade heat

Hubert Girault, Alberto Battistel, Christopher Raymond Dennison, Danick Reynard

Redox flow batteries (RFBs) are rugged systems, which can withstand several thousand cycles and last many years. However, they suffer from low energy density, low power density, and low efficiency. Integrating a Thermally Regenerative Electrochemical Cycle ...

The influence of HCl on the evaporation rates of H2O over water ice in the range 188 to 210 K at small average concentrations

Michel Rossi, Christophe Eric Ludovic Delval

The evaporation flux J(ev)(H2O) of H2O from HCl-doped typically 1.5 mu m or so thick vapor-deposited ice films has been measured in a combined quartz crystal microbalance (QCMB)-residual gas mass spectrometry (MS) experiment. J(ev)(H2O) has been found to s ...

Alkali Silica Reaction and Sulfate Attack: Expansion of Limestone Calcined Clay Cement

Karen Scrivener, Aurélie Rosine Favier

In this paper, two durability issues: Alkali Silica Reaction (ASR) and external sulfate attack were studied. The results of expansion were presented for a Normal Portland cement and a blended cement LC3 containing calcined clay and limestone as supplementa ...

Effectiveness of ammonia reduction on control of fine particle nitrate

Athanasios Nenes, Hairun Guo

In some regions, reducing aerosol ammonium nitrate (NH4NO3) concentrations may substantially improve air quality. This can be accomplished by reductions in precursor emissions, such as nitrogen oxides (NO) to lower nitric acid (HNO3) that partitions to the ...

An “ideal lignin” facilitates full biomass utilization

Jeremy Luterbacher, Li Shuai, Yuan Li

Lignin, a major component of lignocellulosic biomass, is crucial to plant growth and development but is a major impediment to efficient biomass utilization in various processes. Valorizing lignin is increasingly realized as being essential. However, rapid ...

Chemical shifts in molecular solids by machine learning

David Lyndon Emsley, Michele Ceriotti, Albert Hofstetter, Félix Benedito Clément Musil, Sandip De, Federico Maria Paruzzo

Due to their strong dependence on local atonic environments, NMR chemical shifts are among the most powerful tools for strucutre elucidation of powdered solids or amorphous materials. Unfortunately, using them for structure determination depends on the abi ...

Catalytic Supercritical Water Gasification: Continuous Methanization of Chlorella vulgaris

Christian Ludwig, Frédéric Vogel, Gaël Peng, Dominik Refardt

Continuous catalytic supercritical water gasification (CSCWG; 400 degrees C, 28 MPa) of microalgal biomass (Chlorella vulgaris) was carried out at the microalgae production site of ZHAW in Wadenswil (Switzerland) nonstop over a period of 100 h. Microalgae ...

PH of Aerosols in a Polluted Atmosphere: Source Contributions to Highly Acidic Aerosol

Athanasios Nenes, Haiming Yu

Acidity (pH) plays a key role in the physical and chemical behavior of PM2.5. However, understanding of how specific PM sources impact aerosol pH is rarely considered. Performing source apportionment of PM2.5 allows a unique link of sources pH of aerosol f ...
