MAR2PROTECT - Coconut shell derived activated carbon for effective separation of greenhouse gases - DATASET
<p>The need for innovative and efficient adsorptive materials with enhanced structural characteristics that facilitate the selective capture of greenhouse gases (GHGs) is critical. Porosity and surface area play an important role in the adsorptive capture and separation of GHGs, enabling the design of processes that reduce GHGs emissions. This study shows how residual coconut shell (CS) biomass can be reused for the design of novel biomaterials (CS-CO<sub>2</sub>, CS-ZnCl<sub>2</sub>) with structural characteristics that promote the selective adsorption of GHGs. Additionally, the results are compared with those obtained with activated carbon monoliths (ACM) and a Metal-Organic Framework (MOF Fe-BTC) to understand the impact of different porous solid matrices on adsorptive GHG capture. In this context, the adsorption performance of difluoromethane (R-32), pentafluoroethane (R-125), 1,1,1,1-tetrafluoroethane (R-134a), 1,1,1,1-trifluoroethane (R-143a), carbon dioxide (CO<sub>2</sub>), and methane (CH<sub>4</sub>) on CS-CO<sub>2</sub>, CS-ZnCl<sub>2</sub>, ACM and Fe-BTC were measured by gravimetry at 283.15 K, 303.15 K and 323.15 K. The experimental data are correlated using the dual-site Langmuir adsorption model, and the selectivities of the commercial mixtures R-410A, R-407C, R-404A and CO<sub>2</sub>/CH<sub>4</sub> are calculated using the Ideal Adsorption Solution theory (IAST). CS-ZnCl<sub>2</sub> has a higher selectivity for R-125 over R-32 in the separation of R-410A at low pressure, and also a higher selectivity for R-407C due to its larger pore volume. In the separation of the R-404A refrigerant blend, CS-CO<sub>2</sub> adsorbs predominantly R-134a and R-143a over R-125. Finally, the ACM material preferentially adsorbs CO<sub>2</sub> over CH<sub>4</sub>, owing to its large and elongated micropores that favour the adsorption of the smaller molecule. This study introduces novel and innovative materials to enhance the separation of GHGs mixtures, contributing to a reduction in their emissions.</p>
Data from: Promoting success in thin layer sediment placement: effects of sediment grain size and amendments on salt marsh plant growth and greenhouse gas exchange
<p>Thin layer sediment placement (TLP) is a method to mitigate factors resulting in loss of elevation and severe alteration of hydrology, such as sea level rise and anthropogenic modifications, and prolong the lifespan of drowning salt marshes. However, TLP success may vary due to plant stress associated with reductions in nutrient availability and hydrologic flushing or through the creation of acid sulfate soils. This study examined the influence of sediment grain size and soil amendments on plant growth, soil and porewater characteristics, and greenhouse gas exchange for three key US salt marsh plants: <em>Spartina alterniflora, Spartina patens, </em>and <em>Salicornia pacifica. </em>We found that bioavailable nitrogen concentrations (measured as extractable NH<sub>4</sub><sup>+</sup>-N) and porewater pH and salinity were found to have an inverse relationship with grain size, while soil redox was more reducing in finer sediments. This suggests that utilizing finer sediments in TLP projects will result in a more reduced environment with higher nutrient availability, while larger grain-sized sediments will be better flushed and oxidized. We further found that grain size had a significant effect on vegetation biomass allocation and rates of gas exchange, although these effects were species-specific. We found that soil amendments (biochar and compost) did not subsidize plant growth but were associated with increases in soil respiration and methane emissions. Biochar amendments were additionally ineffective in ameliorating acid sulfate conditions. This study uncovers complex interactions between sediment type and vegetation, emphasizing limitations of soil amendments. The findings aid restoration project managers in making informed decisions regarding sediment type, target vegetation, and soil amendments for successful TLP projects.</p>

Experimentally evaluating effects of postfire drought on establishment, growth and survival of two widespread western conifer species; lodgepole pine and Douglas-fir (greenhouse portion of experiment)
This research seeks to understand how drought following wildfires affects the establishment of two widespread Rocky Mountain tree species, lodgepole pine and Douglas-fir. In Yellowstone National Park, warming, drying conditions are leading to increased frequency of severe wildfires that kill existing trees and trigger regeneration of the forest. These trends are expected to continue. Many tree species in Yellowstone are well adapted to fire. Yet, early and abundant seedling establishment after fire is critical for forests to recover. Tree seedlings are particularly sensitive to drought, and evidence suggests that sufficiently dry postfire conditions could cause widespread tree-seedling mortality, with ecological consequences that may last decades. This research will determine how seedlings from two tree species respond to drought conditions expected in the mid-21st century and will identify the physiological mechanisms that drive seedling response to dry conditions. The results of this study will advance understanding of how forests in the western United States will respond to environmental change over coming decades and provide useful information for western land managers who are grappling with increased wildfires.
Disentangling the effects of methanogen community and environment on peatland greenhouse gas production by a reciprocal transplant experiment
<p>1. Northern peatlands consist of a mosaic of peatland types that vary spatially and temporally and differ in their methane (CH<sub>4</sub>) production. Microbial community composition and environment both potentially control the processes that release carbon from anoxic peat either as CH<sub>4</sub> or carbon dioxide (CO<sub>2</sub>), a less potent greenhouse gas than CH<sub>4</sub>. However, the respective roles of these controls remain unclear, which prevents incorporating microbes in the predictions of peatland CH<sub>4</sub> emissions.</p> <p>2. Here, a reciprocal transplant experiment was carried out to separate the influences of microbial community and environment in CH<sub>4</sub> and anaerobic CO<sub>2</sub> production. Peat from an acidic <i>Sphagnum</i> bog and a sedge fen with higher pH was enclosed in membrane bags with a pore size of 0.2 µm, preventing microbial colonization from the outside, and transplanted in the field for two months.</p> <p>3. Potential CH<sub>4</sub> production was primarily controlled by the environment. The conditions in the bog suppressed the initially higher activity of fen methanogens and reduced CH<sub>4</sub> production by 79%. Against expectations, the inhibition was not specific to acetate-using Methanotrichaceae. Reciprocal transplantation favoured Methanosarcinaceae and potentially methylotrophic methanogenesis in general. Bog methanogens, mostly hydrogenotrophic Methanoregulaceae, retained their community structure and activity in the fen with a slight increase (+37%) in CH<sub>4</sub> production.</p> <p>4. Anaerobic CO<sub>2</sub> production was controlled by both the microbial community and the environment. Transplantation led to increased CO<sub>2</sub> production in both bog (+50%) and fen peat (+57%) with distinct bacterial community, showing that the new environment directed more carbon to other anaerobic processes than methanogenesis. 5. Taken together, these results relate differences in CH<sub>4</sub> production of bogs and fens to ecophysiology of specific methanogen groups. The sensitiveness of fen methanogens to the acidic conditions in <i>Sphagnum</i> bogs can help explain the decrease of CH<sub>4</sub> emission in the typical boreal peatland succession from young fens to older bogs. Increase in anaerobic CO<sub>2</sub> vs. CH<sub>4</sub> production with transplantation shows that disturbances of boreal peatlands can activate poorly defined pathways of anaerobic decomposition.</p>
Study on optimization effect of south roof curve of Chinese solar greenhouse
<p><span>To maximize the use of solar energy and increase the utilization area of Chinese solar greenhouse (CSG) land, a solar greenhouse radiation model was established based on previous studies, combining with the law of solar movement, meteorological data, and optical properties of materials. The model is verified by selecting the measured data of typical sunny days. The results show that the optimization of the south roof curve of the greenhouse can not only increase the land-use area in the greenhouse but also increase the solar energy captured by the solar greenhouse. And the CSG in the greenhouse, the land-use area in the greenhouse increased to 42 m<sup>2</sup>, the lighting rate of the south roof, and the lighting rate of the ground increased 15.2% and 0.78% respectively. The amount of interception in the back wall of the greenhouse was reduced by 0.67%, and that in the greenhouse was increased by 2.22%. The optimal structure CSG in Shenyang (span 9 m) is the optimal shoulder height position, obtain the best shoulder height position of the greenhouse, the level of front and bottom Angle is 0.7 m, and the height is 2 m. Combined with the actual greenhouse construction demand, the optimal curve function Y1 and Y2 of the south roof of the greenhouse are calculated. This paper verifies the structural safety of the front roof of the greenhouse after the renovation, and shows that increasing the shoulder height can also increase the structural stability of the greenhouse and strengthen the structural safety of the greenhouse.</span></p>
