Summary: Graphitic carbon materials are synthesized by mixing petroleum coke with Fe-based catalysts and annealing at 1300 degrees C under N-2 atmosphere. Iron or iron oxide catalyst leads to similar graphitic structure formation during heat treatment, with iron oxide catalyst resulting in ordered graphitic structure. Iron-based catalyst decreases turbostratic peak and leads to higher ordered graphite peak. Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM) show similar morphology structure of graphite powder synthesized using iron or iron oxide. Full cell testing using NMC-622 cathode demonstrates good electrochemical properties of the synthesized sample, comparable to commercial graphite.

Summary: This study investigated the wetting behavior of carbonate salts on coal fly ash ceramic substrates with varying expanded graphite contents through contact angle measurements. Results showed that the surface microstructure of substrates and adhesion of salt to substrates influenced the wetting behavior. The presence of salt infiltration during experiments required modification of measured contact angles to eliminate the infiltration effect.

Summary: The wetting behavior of metakaolinite aluminum and silicon basal surfaces was studied using molecular dynamics simulations. It was found that dehydroxylation during calcination weakened the interlayer attraction, leading to particle breakup and increased specific surface area. The altered wettability was attributed to water-clay interactions mechanisms.

Summary: When calculating the surface tension of an ideal solid surface, it is suggested to measure the contact angles of standard liquids instead of directly using the calculated surface tension values. This approach provides a more accurate assessment of wettability of the solid surface, and the optimal choice of liquids and weights can be determined through experimentation.

Summary: The literature review suggests that plasma treatment can effectively improve seed wettability and promote germination, with the optimal power density being 1 W cm(-3). Increased treatment time enhances wettability and germination, but saturation occurs at a certain level. Various parameters such as discharge type, power density, treatment time, and seed type play roles in influencing wettability and germination, rather than being decisive factors.

Summary: Non-conventional amines are being researched worldwide to overcome the limitations of traditional amines like MEA and MDEA. Adequate process and thermodynamic models are crucial for understanding the applicability and performance of these amines in CO2 absorption, but studies on process modeling for these amines are limited. This study used rate-based modeling and Deshmukh-Mather method to model CO2 absorption by DETA solution in a packed column, validated the model with experimental data, and conducted a sensitivity analysis of mass transfer correlations. The study also compared the CO2 absorption efficiency of DETA solution with an ionic solvent [bmim]-[PF6] and highlighted the importance of finding optimum operational parameters for maximum absorption efficiency.

Summary: The utilization of smart water in EOR operations has gained attention, but more research is needed to understand the complex mechanisms involved. This study investigated the interfacial tension between smart water and crude oil, considering factors such as salt, pH, asphaltene type, and aged smart water. The results revealed that the hydration of ions in smart water plays a key role in its efficacy, with acidic and basic asphaltene acting as intrinsic surfactants. The pH also influenced the interfacial tension, and the aged smart water's interaction with crude oil depended on asphaltene type, salt, and salinity.

Summary: In this study, high-performance solid catalysts based on phosphotungstic acid (HPW) supported on Zr-SBA-15 were synthesized and evaluated for the one-pot conversion of furfural (FUR) to γ-valerolactone (GVL). The catalysts were characterized using various techniques, and the ratio of HPW and Zr was found to significantly affect the selectivity of GVL. The HPW/Zr-SBA-15 (2-4-15) catalyst exhibited the highest GVL yield (83%) under optimized reaction conditions, and it was determined that a balance between Bronsted acid sites (BAS) and Lewis acid sites (LAS) was crucial for achieving higher catalytic performance.
