Diel and seasonal courses of ambient carbon dioxide concentration and their effect on productivity of the epilithic lichen Lecanora muralis in a temperate, suburban habitat [PDF]

, 2008
Ambient CO₂ concentration (together with CO₂ exchange and microclimate) was recorded every 30 min for 15 months for Lecanora muralis growing in the Botanical Garden Würzburg (Germany, northern Bavaria), a habitat on the outskirts of the city. Annual mean

Cu‐Based MOF/TiO2 Composite Nanomaterials for Photocatalytic Hydrogen Generation and the Role of Copper

Advanced Functional Materials, EarlyView.
HKUST‐1/TiO2 composite materials show a very high photocatalytic hydrogen evolution rate which increases as a function of the irradiation time until reaching a plateau and even surpasses the performance of the 1%Pt/TiO2 material after three photocatalytic cycles.

Revised estimates of ocean-atmosphere CO2 flux are consistent with ocean carbon inventory

Nature Communications, 2020
Ocean uptake of carbon dioxide impacts the climate, but flux estimates from surface measurements have not been corrected for temperature differences between surface and water sampling depth. Making that correction, the authors find previous estimates for

Ocean acidification: implications for coral reefs [PDF]

, 2008
Acidification due to ocean uptake of carbon dioxide will have serious consequences for coral reefs worldwide over the course of this century. The surface ocean now absorbs up to 30 percent of the yearly emissions of carbon dioxide. The absorbed carbon

Optimizing Carbon Dioxide Uptake and Carbon Dioxide‐Methane Selectivity of Oxygen‐Doped Porous Carbon Prepared from Oxygen Containing Polymer Precursors [PDF]

ChemistrySelect, 2017
Abstract The reproducible synthesis is reported for oxygen containing porous carbons (OPC) by the KOH activation at 500–800 °C of two oxygen containing precursor polymers: polyfurfuryl alcohol (PFFA) and polyanisyl alcohol (PAA) yielding FFA‐OPC and AA‐OPC, respectively.

Atomic Size Misfit for Electrocatalytic Small Molecule Activation

Advanced Functional Materials, EarlyView.
This review explores the application and mechanisms of atomic size misfit in catalysis for small molecule activation, focusing on how structural defects and electronic properties can effectively lower the energy barriers of chemical bonds in molecules like H2O, CO2, and N2.

Adsorption measurement and dual-site Langmuir model II: Modeling and prediction of carbon dioxide storage in coal seam

Energy Exploration & Exploitation, 2019
Accurate estimation of carbon dioxide adsorption capacity in coal seam is very important for planning the carbon dioxide storage efforts of carbon capture and storage technology; however, an appropriate model is needed to convert the measured adsorption ...

Seasonal, synoptic, and diurnal-scale variability of biogeochemical trace gases and O2 from a 300-m tall tower in central Siberia [PDF]

, 2008
We present first results from 19 months of semicontinuous concentration measurements of biogeochemical trace gases (CO2, CO, and CH4) and O2, measured at the Zotino Tall Tower Observatory (ZOTTO) in the boreal forest of central Siberia.

Calcite is an efficient and low-cost material to enhance benthic weathering in shelf sediments of the Baltic Sea

Communications Earth & Environment
Recent studies have proposed calcite and dunite as possible alkaline materials for enhanced benthic weathering in shallow depocenters of the Baltic Sea as a marine carbon dioxide removal strategy.
