Two-dimensional carbon-based nanomaterials (2D-CNM) have been extensively utilized to address dendrite, leveraging their dimensional attributes such as lattice compatibility and feasible assembly. Despite the reviews on carbon materials in metal batteries, the correlation between the 2D structure of 2D-CNMs and dendrite suppression has not been reported. This study aims to fill this gap. It begins by introducing the dendrite formation mechanism and 2D-CNM advantages. Subsequent sections discuss how the pore structure engineering, surface chemistry, and assembly of 2D-CNM contribute to dendrite suppression from perspectives of ion mass transfer and electrodeposition electrode reaction.

They are all carbonaceous, but their distinct composition in both organic and inorganic fractions could impact properties/compositions of pyrolytic products. The detailed impacts were investigated herein by conducting pyrolysis of poplar, spirulina and pig manure at 500 °C and systematic analysis of resulting products. The results showed that bio-oil yield from poplar or spirulina was roughly 2 times of that from pig manure, due to their abundant organic components. However, the yield of biochar from poplar or spirulina was less than half of that from pig manure, but, on organic basis (excluding ash in biochar), the biochar yield was the highest from pyrolysis of poplar. Abundant inorganic components in pig manure formed ash-rich biochar (73.2 %), which was much higher than the ash content in spirulina-biochar (23.9 %) or poplar-biochar (9.0 %). This led to remarkably lower heating value (5.3 versus 26.3 MJ/kg for poplar-biochar) and much lower overall combustion index. Additionally, more intensive cracking induced by low thermal stability of organics in spirulina and pig manure, together with their abundant inorganics (i.e. SiO<sub>2</sub>, CaCO<sub>3</sub> and KCl), resulted in remarkably lower carbon yields than that from pyrolysis of poplar. This, however, reduced the activation energy in pyrolysis of spirulina. Biological fibrous structures of poplar could be inherited by poplar-biochar, while morphology of pig manure-char was very irregular. Melting/agglomeration of proteins and lipids in spirulina formed spirulina-biochar of densified structures with smooth surface.</div></div>","PeriodicalId":271,"journal":{"name":"Chemical Engineering Science","volume":"309 ","pages":"Article 121512"},"PeriodicalIF":4.1,"publicationDate":"2025-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143582551","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Owing to the poly iron/poly aluminum coagulants usually used in wastewater disposal and finally into the sludge, sludge ash contains a high proportion of iron oxides. To investigate whether sludge ash has the potential to be an economic OC or an auxiliary iron-based OC, iron-rich sludge ash (IRSA), Fe/Al-OC, and their mixed OC in equal proportions (Fe1Ash1) were tested in 30 redox cycles using a thermogravimetric analyzer (TG) and tubular furnace. The TG analysis combined with BET and SEM results could present the following results. The IRSA shows a high oxygen-carrying capacity only in the first two cycles; Fe/Al-OC has a lower oxygen-transferring capacity, the Fe-phase enrichment and mechanical strength impairment are kept during multi-cycling reactions. As for Fe1Ash1, the oxygen-carrying capacity was higher than the theoretically weighted value, and the sintering of the sludge ash was slowed down. However, fragmentation and the low-melting-point Fe-containing components in the sludge ash were still present, and the released components and fragmented under higher temperature adhered to the surface and increased the surface Fe phase density of the Fe/Al-OC particle, the Fe concentration difference between the surface and section inhibited the migration of section Fe moving to the surface. Consequently, by blending IRSA, the iron phase migration of Fe/Al-OC was inhibited and the oxygen transfer performance was improved.</div></div>","PeriodicalId":271,"journal":{"name":"Chemical Engineering Science","volume":"309 ","pages":"Article 121501"},"PeriodicalIF":4.1,"publicationDate":"2025-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143576120","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such conditions are typically found in the oil reservoirs in pre-salt layer. In this work, we investigate the behavior of thermodynamic properties of natural gas mixtures, primarily composed of methane (CH<sub>4</sub>), light hydrocarbons, and non-hydrocarbon gases, in pre-salt layer conditions employing molecular dynamics simulations with the TraPPE and OPLS force fields. We computed density, speed of sound, isobaric and isochoric heat capacities, Joule-Thomson coefficient, isothermal compressibility, and thermal expansion coefficient over a temperature range of 323.15 to 413.15 K and a pressure range of 10 to 60 MPa. To enhance the accuracy of our results, we employed the Multistate Bennett Acceptance Ratio (MBAR) estimator. The values obtained for density and speed of sound showed strong agreement with available experimental data. Given the scarcity of experimental data for the other properties, we validated our simulation results against the Soave-Benedict-Webb-Rubin (SBWR) equation of state. Notably, the rigid-molecule force fields provided a more accurate description of the thermodynamic properties of the natural gas mixture studied, underscoring its efficacy in modeling complex fluid behaviors under extreme conditions.","PeriodicalId":271,"journal":{"name":"Chemical Engineering Science","volume":"8 1","pages":""},"PeriodicalIF":4.7,"publicationDate":"2025-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143576340","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In nature and practical applications, the motion of droplets on non-uniform surface structures is often involved, yet the resulting asymmetric spreading and rewetting phenomena have not received sufficient attention. This poses a significant barrier to further refining the control of droplets and broadening their applications. Here we proposed a refined dynamic model and study the behavior of spray droplets on semi-cylindrical curved surfaces using the pseudopotential multi-relaxation-time scheme of lattice Boltzmann method (MRT-LBM). Our results indicate that the peripheral annular flow of the droplet preferentially spreads along the tangential direction. The axial retraction effect further squeezes the liquid to spread laterally, resulting in a maximum spreading length ratio of 1.3 for the tangential to axial directions. This asymmetric behavior is significantly enhanced with the increase of the droplet’s Weber number and the curvature of the structure (<em>R/R</em><sub>0</sub>). We also discussed the effects of asymmetric retraction and initial velocity during the droplet impact process on the reduced contact time of up to ∼ 32 %, as well as the rewetting phenomenon. The proposed model should enable accurate simulation of the droplet dynamics on various non-uniform structural surfaces. It highlights a systematic analysis of the complex interactions between initial conditions, structural parameters, liquid properties, and surface tension that affect droplet dynamics, providing an in-depth understanding of the mesoscale interactions of droplets on non-uniform structural surfaces.</div></div>","PeriodicalId":271,"journal":{"name":"Chemical Engineering Science","volume":"309 ","pages":"Article 121470"},"PeriodicalIF":4.1,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143570079","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
