The influence of water-saturation on the strength of volcanic rocks and the stability of lava domes

Marie Estelle Solange Violay, Michael Heap

The rocks forming a volcanic edifice or dome are typically saturated or partially-saturated with water. However, most experiments aimed at better understanding the mechanical behaviour of volcanic rocks have been performed on dry samples, and therefore mos ...

Selecting the best AOP for isoxazolyl penicillins degradation as a function of water characteristics: Effects of pH, chemical nature of additives and pollutant concentration

César Pulgarin, Paola Villegas Guzman

To provide new insights toward the selection of the most suitable AOP for isoxazolyl penicillins elimination, the degradation of dicloxacillin, a isoxazolyl penicillin model, was studied using different advanced oxidation processes (AOPs): ultrasound (US), ...

Global impact of mineral dust on cloud droplet number concentration

Athanasios Nenes

The importance of wind-blown mineral dust for cloud droplet formation is studied by considering (i) the adsorption of water on the surface of insoluble particles, (ii) particle coating by soluble material (atmospheric aging) which augments cloud condensati ...

Clumped isotope fractionation during phosphoric acid digestion of carbonates at 70°C

Marie Estelle Solange Violay

The application of clumped isotopes (Delta(47)) in carbonate minerals as a sensitive temperature proxy in paleo-environments depends on a well-constrained clumped isotope fractionation for the necessary step of phosphoric acid digestion of the carbonate mi ...

Influence of crustal dust and sea spray supermicron particle concentrations and acidity on inorganic NO3- aerosol during the 2013 Southern Oxidant and Aerosol Study

Satoshi Takahama, Robin Lewis Modini

Inorganic aerosol composition was measured in the southeastern United States, a region that exhibits high aerosol mass loading during the summer, as part of the 2013 Southern Oxidant and Aerosol Study (SOAS) campaign. Measurements using a Monitor for AeRos ...

Quantifying sensitivities of ice crystal number and sources of ice crystal number variability in CAM 5.1 using the adjoint of a physically based cirrus formation parameterization

Athanasios Nenes

We present the adjoint of a cirrus formation parameterization that computes the sensitivity of ice crystal number concentration to updraft velocity, aerosol, and ice deposition coefficient. The adjoint is driven by simulations from the National Center for ...

Effect of calcification on agarose gel stiffness and integration strength with Bone

Jérôme Hollenstein

The zone of calcified cartilage (ZCC) is critical for the normal attachment of articular cartilage to bone as well as to the biomimetic bioengineering of osteochondral tissue constructs. However, relatively few osteochondral tissue engineering approaches h ...

Distribution of platinum-group elements and Os isotopes in chromite ores from Mayari-Baracoa Ophiolitic Belt (eastern Cuba)

Anders Meibom, Reto Frei

The Mayari-Baracoa ophiolitic belt in eastern Cuba hosts abundant chromite deposits of historical economic importance. Among these deposits, the chemistry of chromite ore is very variable, ranging from high Al (Cr#=0.43-0.55) to high Cr (Cr#=0.60-0.83) com ...

Equilibrium and kinetic aspects of soddyite dissolution and secondary phase precipitation in aqueous suspension

Janet Gordon Hering

The dissolution and transformation of soddyite ([UO2]2SiO4·2H2O) have been examined in aqueous suspension at pH 6 and 0.01 M NaNO3. Soddyite is an important component of the paragenetic sequence of secondary minerals that arises from the weathering of uran ...

The leaching behavior of cement stabilized air pollution control residues: A comparison of field and laboratory investigations

Christian Ludwig

The factors controlling leachate composition of cement stabilized air pollution control (APC) residues (41% APC residues, 22% cement, 3% Na2CO3, and 32% water, w/w) have been investigated both in the laboratory ansi in a pilot landfill. Batch leaching and ...
