Air-water exchange and vertical profiles of organic carbon in a subarctic fjord
Air-water exchange vertical profiles organic carbon subarctic fjord
2014/4/17
In this article, we examine the air-sea exchange of exchangeable organic carbon (OC) as well as the internal pools and sources within a subarctic fjord. Air-water fluxes of OC ranged from an uptake of...
Reaction Kinetics of Carbon Dioxide with Phenyl Glycidyl Ether by TEA-CP-MS41 Catalyst
Carbon dioxide absorption Phenyl glycidyl ether Triethylamine MCM-41 catalyst
2010/9/8
CP-MS41 was synthesized by hydrolysis of tetraorthosilicate, as a silicon source, with 3-chloropropyltriethoxysilane as an organosilane using cetyltrimethylammonium bromide as a template. TEA-CP-MS41 ...

Cover crop system has shown a potential approach to improving carbon sequestration and environmental quality. Six of each winter and summer cover crops were subsequently grown in two soils, Krome grav...
Carbon-Nanotube-Deposited PLC Waveguide for Four-Wave Mixing based Wavelength Conversion
Nonlinear optical materials Nonlinear optics four-wave mixing
2015/6/9
We demonstrated a novel carbon-nanotube-deposited PLC waveguide for four-wave-mixing-based wavelength conversion. Tunable wavelength converted 10-Gb/s NRZ signal is achieved with 3-dB power penalty. T...
Highly efficient electrospray process for carbon nanotube- based laser pulse formers
Nanomaterials Nonlinear optical devices Mode-locked laser
2015/6/9
We demonstrate laser pulsation of CNTs deposited by electrospray process that ensures target-localized and homogeneous deposition of CNTs with dramatically improved deposition efficiency (>95%). Resul...
The Substrate Carbon Consumption and Metabolite Production to Describe the Growth of Geotrichum candidum and Penicillium camemberti on Glucose and Amino Acids
batch culture carbon substrates Geotrichum candidum Penicillium camemberti unstructured models biomass yield
2010/8/11
Amino acids had previously been characterized based on their ability to be assimilated as carbon sources by Penicillium camemberti and Geotrichum candidum. For each microorganism, three groups of amin...
