Fiber-Tip Polymer Microcantilever for Fast and Highly Sensitive Hydrogen Measurement

Giovanni Dietler, Sandor Kasas, Jiangtao Zhou, Leonardo Venturelli, Yiping Wang, Chaohui Li, Meng Zhu, Cong Xiong

Hydrogen as an antioxidant gas has been widely used in the medical and biological fields for preventing cancer or treating inflammation. However, controlling the hydrogen concentration is crucial for practical use due to its explosive property when its vol ...

Fine Particle Iron in Soils and Road Dust Is Modulated by Coal-Fired Power Plant Sulfur

Athanasios Nenes

Transition metal ions, such as water-soluble iron (WS-Fe), are toxic components of fine particles (PM2.5). In Atlanta, from 1998 to 2013, a previous study found that WS-Fe was the PM2.5 species most associated with adverse cardiovascular outcomes. We exami ...

Viral Metagenomic Content Reflects Seawater Ecological Quality in the Coastal Zone

Grégoire Marie Octave Edouard Michoud, Stylianos Fodelianakis

Viruses interfere with their host's metabolism through the expression of auxiliary metabolic genes (AMGs) that, until now, are mostly studied under large physicochemical gradients. Here, we focus on coastal marine ecosystems and we sequence the viral metag ...

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 ...

A von Hamos spectrometer for in situ sulfur speciation by non-resonant sulfur K alpha emission spectroscopy

Dominik Kinschel

A von Hamos geometry based wavelength dispersive spectrometer combined with an in situ reactor cell has been developed to measure non-resonant sulfur K alpha emission for the in situ speciation of low concentrations of sulfur. The spectrometer operates at ...

Hypobromous Acid as an Unaccounted Sink for Marine Dimethyl Sulfide?

Urs von Gunten, Boris Droz

Marine emissions of dimethyl sulfide (DMS) to the atmosphere play a fundamental role in the global sulfur (5) cycle and have important consequences for the Earth's radiative balance. In the ocean, DMS is mainly produced by marine algae and bacteria via cle ...

Mineral equilibria and thermodynamic uncertainties in the geothermometrical characterisation of carbonate geothermal systems of low temperature. The case of the Alhama-Jaraba system (Spain)

Javier Reguera Gomez, Maria Pilar Asta Andres

Geothermometrical characterisation of low-temperature, carbonate-evaporitic geothermal systems is usually hampered by the lack of appropriate mineral equilibria to successfully use most of the classical geothermometers and/or by the thermodynamic uncertain ...

Wafer-scale MOCVD growth of monolayer MoS2 on sapphire and SiO2

Aleksandra Radenovic, Andras Kis, Thomas La Grange, Ke Liu, Michal Daniel Macha, Yanfei Zhao, Hokwon Kim, Huanyao Cun

High-quality and large-scale growth of monolayer molybdenum disulfide (MoS2) has caught intensive attention because of its potential in many applications due to unique electronic properties. Here, we report the wafer-scale growth of high-quality monolayer ...

Detailed Analysis of Estimated pH, Activity Coefficients, and Ion Concentrations between the Three Aerosol Thermodynamic Models

Athanasios Nenes, Yan Feng

In this work, we utilize a rich set of simulated and ground-based observational data in Tianjin, China to examine and compare the differences in aerosol acidity and composition predicted by three popular thermodynamic equilibrium models: ISORROPIA II, the ...
