Abstract A novel method was developed to prepare threedimensional structures with desired shapes used as templates for cell transplantation. The produced biomaterials are highly porous large surface/volume and provide the necessary space attachment proliferation of transplanted cells. processing technique calls formation a composite material nonbonded fibers embedded in matrix followed by thermal treatment selective dissolution matrix. To evaluate technique, poly(glycolic acid) (PGA) fiber...
Microbially enhanced coalbed methane (MECBM) production has drawn significant interest worldwide in recent years since the direct combustion of fossil energy sources including oil and coal, would cause global environmental pollution have detrimental effects on human health. MECBM shows great potential producing biomethane thus reducing fuel related pollution. Although much progress been achieved understanding mechanism how coal is converted into biomethane, studies shown that biodegradation...
The separation of ethylene (C2H4) from ethane (C2H6) is a critical yet energy-intensive process in the chemical industry, demanding energy-efficient and cost-effective solutions. Here, we report Li+-exchanged silicoaluminophosphate RHO zeolite (Li-SAPO-RHO) with unprecedented selectivity for C2H4 over C2H6. This exceptional performance attributed to synergy between H+ Li+ ions strategically positioned at flexible eight-membered ring (8MR) gates zeolite. These effectively modulate transport...
Methane is a renewable and environmentally friendly energy source. Microbial degradation not only increases the methane content of coal seams but also facilitates migration coal-bed (CBM). However, there currently limited research on internal factors that govern adsorption capacity production mechanisms in coals with varying degrees metamorphism. To investigate constraints different ranks anaerobic fermentation, Fourier transform infrared spectroscopy, low-temperature nitrogen adsorption,...
This study researched the geochemical origin of coalbed methane (CBM) in three mining areas Huaibei coalfield and distribution different gases. The Rock-Eval data indicate that coal coaly mudstone this are both good gas-source rocks within gas generation window. large ranges isotope (δ13CCH4 = −42.8‰ to −75.5‰; δDCH4 −153.2‰ −228.1‰; δ13CCO2 +8.2‰ −24.3‰) reflect complicated formation mechanism evolutionary process CBM. Both thermogenic biogenic present varying degrees, with being...
Bioconversion of coal to methane occurs in the coalbed aquifer environment. To investigate evidence biodegradation from coalbed-produced water, we collected six field water samples Dafosi gas and prepared one laboratory-simulated sample indoor anaerobic microbial degradation with highest compound concentration as two reference standards. Gas chromatography–mass spectrometry was used detect organic type, concentration, differences biomarker sensitivity. Results indicate that extracted matter...
Nucleolus is a membrane-less organelle where ribosomes are assembled, and ribosomal RNAs (rRNAs) transcribed processed. The assembled composed of proteins rRNAs synthesize for cell survival. In plants, the loss nucleolar often causes gametophytically or embryonically lethality. amount under stringent regulation according to demand partially switched off by epigenetic modifications. However, molecular mechanism selective activation silencing still unclear, transcriptional coordination also...
Organic shale in coal-bearing strata contains a large amount of gas resource China. The organic is typically interlayered with coal beds and tight sandstone, thus, joint development the three unconventional gases, bed methane, gas, becoming frontier topic. In this paper, an integrated characterization was implemented through systematic series measurements to assess potential Huainan–Huaibei coalfield. According X-ray diffraction, quartz, kaolinite, mixed illite/smectite (I/S) are major...
Pore structure plays an essential role in the reservoir heterogeneity and methane adsorption capacity. Significant progress has been made pore classification of porous materials (such as coal shale). Considering characterization measures measuring range high-pressure mercury intrusion porosimetry low-pressure N 2 /CO gas adsorption, integrated for shale is provided. They are micropore (<2 nm), mesopore (2–100 macropore A (100 nm–1 µm), B (1–10 micro-fracture (>10 µm). For samples from...
Coalbed gas or coalbed methane (CBM) is a vital hydrocarbon which mainly absorbed in the surface of coal matrix and has multiple benefits as being effective development utilization. To determine origin, distribution stable carbon isotopic composition for methane, its constraint Middle Jurassic strata Dafosi mine area southern margin Ordos Basin, nine CBM samples were collected from pumping wells at surface, arranged along three profiles located different tectonic areas. The components...
Coalbed methane (CBM) resources formed biogenically and thermogenically have been discovered in the Permian coalbeds of Huaibei coalfield. Four coals, three mudstones, five coalbed-produced water samples collected from Linhuan, Luling, Haizi coal mines coalfield were characterized geochemically biologically to gain an understanding biogenic generation potential microbial communities involved situ water-enriched samples. The 16S rRNA gene high-throughput sequencing results showed that...
