Simple Rectangular Gratings as a Near-Field “Anti-Reflection” Pattern for GaSb TPV Cells

open access: yesScientific Reports, 2017
We show theoretically that 2D rectangular gratings on the surface of GaSb can serve as an “anti-reflection” pattern for nano-gap thermophotovoltaic (TPV) devices, which significantly enhances near-field radiative flux from the emitter to a GaSb cell ...

Improved quantification of Chinese carbon fluxes using CO2/CO correlations in Asian outflow [PDF]

open access: yes, 2004
[1] We use observed CO2:CO correlations in Asian outflow from the TRACE-P aircraft campaign (February–April 2001), together with a three-dimensional global chemical transport model (GEOS-CHEM), to constrain specific components of the east Asian CO2 ...

Biological Carbon Sequestration and Carbon Trading Re-Visited [PDF]

open access: yes, 2009
Biological activities that sequester carbon create CO2 offset credits that could obviate the need for reductions in fossil fuel use. Credits are earned by storing carbon in terrestrial ecosystems and wood products, although CO2 emissions are also ...

Electrochemical CO2 Reduction Using Gas Diffusion Electrode Loading Ni-doped Covalent Triazine Frameworks in Acidic Electrolytes

open access: yesElectrochemistry, 2020
Ni-doped covalent triazine frameworks (Ni-CTF) has been known as an efficient electrocatalysts that achieve conversion of carbon dioxide (CO2) to carbon monoxide (CO) with the faradaic efficiency (FE) exceeding 90% in neutral electrolytes. Here we report

Selective evolution of methanogenic communities by β-lactam antibiotics promotes methane production

open access: yesMicrobiology Spectrum
Biomethane, a clean energy source, plays a crucial role in addressing global energy and environmental challenges. However, its production has long been limited by the complexity of methanogenic precursor synthesis and the involvement of diverse microbial
