Chinese cities need independent but synergetic dual-carbon abatement roadmaps to mitigate climate change and achieve carbon neutrality. Using source-level data, we develop a time-series, full-scale emission inventory for all from 2005 2020, exploring associated heterogeneous homogeneous patterns. We find that 31% of have had significant peak, with the main driver being intensity reductions through efficiency gains structural improvements. Despite discrepant levels socioeconomic determinants,...
Strain LCG007, isolated from Lu Chao Harbor's intertidal water, phylogenetically represents a novel genus within the family Rhodobacteraceae. Metabolically, it possesses wide array of amino acid metabolic genes that enable to thrive on both acids or peptides. Also, could hydrolyze peptides containing D-amino acids, highlighting its potential role in cycling refractory organic matter. Moreover, strain LCG007 utilize various carbohydrates, including mannopine and D-apiose-compounds primarily...
Gas drainage at low gas permeability coal seam is a main barrier affecting safety and efficient production in mines. Therefore, the research application of technology key factor for control mine. In order to improve effect, this paper establishes three-dimensional solid-gas-liquid coupling numerical model, amounts different schemes are examined inside overburden material around goaf. The Yangquan mine area selected case study, movement regularity emission characteristics analyzed detail, as...
Summary Heterogeneously distributed micromineral aggregates (MMAs) are common in shale reservoirs. The interfaces between these MMAs and the surrounding minerals significantly affect fracture propagation behaviors during oil exploitation. In this paper, concept of interfacial transition zone (ITZ) (e.g., striped barite, pyrite, calcite, apatite blocks, bedding plane) mineral is introduced. Due to small thickness ITZ, its mechanical properties very difficult determine by traditional standard...
Abstract It is well known that a solid surface will be charged when it comes into contact with liquid, especially electrolyte solutions. The charge influences ion distribution and transport and, therefore, affects the chemical reaction. Such an effect may become significant in micropores/nanopores electrical double layer thickness comparable to pore size, but this has never been studied. This work investigates coupled electrokinetic reactive micropores using mesoscopic modeling. We...
Accurate tree height and diameter at breast (dbh) are important input variables for growth yield models. A total of 5503 Chinese Metasequoia trees were used in this study. We studied 53 fitted models, which 7 linear models 46 non-linear These divided into two groups single multivariate according to the number independent variables. The results show that allometry equation has as variable can better reflect change height; addition prediction accuracy composite is higher than Although age not...
Recent studies reported that highly abundant alkane content exists in the ~11,000 m sediment of Mariana Trench, and a few key alkane-degrading bacteria were identified Trench. At present, most on microbes for degrading hydrocarbons performed mainly at atmospheric pressure (0.1 MPa) room temperature; little is known about which could be enriched with addition n-alkanes under in-situ environmental temperature conditions hadal zone. In this study, we conducted microbial enrichments from Trench...
In this work, a series of ammonium–lauric salts (ALS) was prepared with lauric acid and amines as small molecular shale swelling inhibitor. The inhibitors were screened by the linear expansion test first, result shows that inhibitor diethylenetriamine mole ratio 2:1 (ALS-2) displays excellent inhibition effect on hydration bentonite. ALS-2 to bentonite fully evaluated various methods in following including clay particle distribution measurement. results show has superior performance inhibit...
Abstract Perfluorooctanoic acid was photocatalytically decomposed by using TiO2/Ni–Cu, and a small bias potential (−0.1 V) applied on TiO2/Ni–Cu electrode greatly enhanced its decomposition.
In this paper, a series of poly ammonium shale inhibitors were prepared from diethylamine, epichlorohydrin, and melamine (DEM) their inhibition to evaluated by bentonite linear expansion test, anti-swelling experiments, mud ball experiments. Additionally, other properties drilling fluid treated evaluated. Anti-swelling results showed that rate DEM-8 reaches up 97.8% when its concentration 0.8%. Mud experiment evaluation has strong inhibitive capability hydration swelling controlling the...
Understanding and predictions of the local thermal-hydraulic performance supercritical CO2 in channels printed circuit heat exchanger geometries are great importance to design optimization pre-cooler recuperators cycle. The flow transfer horizontal semicircular zigzag channel during cooling near critical or pseudo-critical point have been numerically investigated this paper. effects thermophysical property variations, mass flux, geometrical parameters on discussed.

A good understanding of CO2–brine–rock interactions that cause microscale damage to the microstructure sandstone, affecting pore fluid transport and reservoir stability, is important for studying storage efficiency during CO2 storage. In this study, equipment first designed saturate rock samples using CO2–brine under in situ conditions then homogeneous heterogeneous sandstone are saturated 30 days with without confining pressure (20 MPa). Through scanning electron microscopy (SEM)...
