Estimation of Organic and Elemental Carbon using FT-IR absorbance spectra from PTFE Filters

Organic carbon and elemental carbon are major components of atmospheric PM. Typically they are measured using destructive and relatively expensive methods (e.g., TOR). We aim to reduce the operating costs of large air quality monitoring networks using FT-I ...

Estimation of Organic and Elemental Carbon using FT-IR absorbance spectra from PTFE Filters

Satoshi Takahama, Giulia Ruggeri, Matteo Reggente

Organic carbon (OC) and elemental carbon (EC) are major components of atmospheric PM. Typically OC and EC concentrations are measured using thermal optical methods from samples collected on quartz filters. However, these measurements are destructive and re ...

Predicting ambient aerosol thermal–optical reflectance measurements from infrared spectra: elemental carbon

Satoshi Takahama

Elemental carbon (EC) is an important constituent of atmospheric particulate matter because it absorbs solar radiation influencing climate and visibility and it adversely affects human health. The EC measured by thermal methods such as thermal-optical refl ...

Structure-property relationships based on Hammett constants in cyclometalated iridium(III) complexes: their application to the design of a fluorine-free FIrPic-like emitter

Mohammad Khaja Nazeeruddin, Rosario Scopelliti, Ursula Röthlisberger, Ivano Tavernelli, Basile Curchod, Julien Edouard Frey

While phosphorescent cyclometalated iridium(III) complexes have been widely studied, only correlations between oxidation potential EOX and Hammett constant sigma, and between the redox gap (Delta E-REDOX = E-OX-E-RED) and emission or absorption wavelength ...

Homogeneous Catalytic Dehydrogenation of Formic Acid: Progress Towards a Hydrogen-Based Economy

Paul Joseph Dyson, Gabor Laurenczy

One of the limiting factors to a hydrogen-based economy is associated with the problems storing hydrogen. Many different approaches are under evaluation and the optimum approach will not be the same for all applications, i.e., static, mobile, small and lar ...

High aspect ratio etching of nanopores in PECVD SiC through AAO mask

Jürgen Brugger, Songmei Wu, Vaida Auzelyte, Wei Tang

We present in this work the fabrication of high aspect ratio nanopores in 500 nm PECVD SiC films through AAO (anodic aluminum oxide) mask. The initial AAO thin film is 180 nm thick and the diameter of nanopores is 33 ± 7 nm. We have used three plasma chemi ...

Physicochemical and Electrochemical Properties of Etched GaP(111)A and GaP(111)B Surfaces

Blake William Erickson

The observable chemical, electrochemical, and morphological features of GaP(111) surfaces after wet chemical etching have been assessed using X-ray photoelectron spectroscopy, atomic force microscopy, and electrochemical impedance spectroscopy. HF(aq), NH4 ...

SOLPS modelling of ELMing H-mode

Barbora Bruant Gulejová

Numerical simulation of the tokamak scrape-off layer (SOL) is an essential tool for the prediction of the conditions to be expected in future fusion reactors such as the ITER project, now under construction in Southern France. One particularly important is ...

Response of terrestrial N2O and NOx emissions to abrupt climate change

Jed Oliver Kaplan, Mirjam Pfeiffer

Being a potent greenhouse gas, N2O emitted by the terrestrial biosphere during abrupt climate change events could have amplified externally forced warming. To investigate this possibility, we tested the sensitivity of terrestrial N2O emissions to an abrupt ...
