Summary: This study reviews the influence of material selection, printing parameters, and temperature parameters on the mechanical properties of 3D printed parts. It emphasizes the interactions between printing parameters and the statistical methods required to identify these interactions. Choosing the right parameters can increase mechanical properties by up to 60% or render other parameters insignificant, while specific settings of certain parameters can completely inverse the influence trend of other parameters. Trends for future research are suggested.

Summary: An innovative method for creating lab-on-a-chip microflow reactors was developed based on in-depth studies of chemical processes at plastic-metal interfaces. The method involves 3D printing the reactor core with ABS plastic, followed by electroless copper and galvanic nickel plating for a durable and versatile design. Despite the simple procedure and low-cost materials used, the reactors exhibited excellent chemical resistance, modular design capabilities, and high performance in a variety of chemical processes targeting biologically active molecules.

Summary: This study evaluated the shrinkage, accuracy, and mechanical properties of a newly developed 3D printing resin material and compared it with three commercially available resins. The results showed that the new resin exhibited lower shrinkage and higher accuracy compared to the commercial resins. It also had similar strength and modulus but slightly differed in properties compared to the commercial resins. Therefore, the new resin shows promise for dental applications.

Summary: The microstructure of coal plays a significant role in resource enrichment and graphitization. This study characterized the microstructure of coal cores from the Upper Paleozoic coal seams in the southern Qinshui Basin using atomic force microscopy (AFM) and high-resolution transmission electron microscopy (HRTEM). The results showed that the carbon structure had a local parallel alignment with stacked layers, and the interlayer spacing decreased during coalification and graphitization. The matrix morphology tended to be regular and smooth in high rank coal. These findings provide supplementary information for coalification and graphitization theory and have practical applications in coal resource development and utilization of coal derived materials.

Summary: The swelling strain caused by methane adsorption in coal affects reservoir permeability, and the interaction between different scales of coal pores and adsorption behavior was investigated. Larger coal particle size leads to smaller temperature variation during adsorption and more capillary condensation of methane. Higher temperature results in more concentrated distribution of adhesion in coal.

Summary: This study investigated the water vapor sorption behavior in different maturity coal samples and identified two types of water adsorption mechanisms: attachment to oxygen functional groups and pore filling in hydrophilic and hydrophobic pores, respectively. The differences in water adsorption characteristics were found to be influenced by pore volume and the proportion of hydrophilic pores. The results also showed that water adsorption on methane adsorption in coal was attributed to the amount and proportion of hydrophilic pores.

Summary: Forced imbibition in shale reservoirs is crucial for efficient recovery of shale gas, but it can also lead to low flowback efficiency and reservoir damages. This study investigated imbibition behaviors in Longmaxi shales under four different boundary conditions using nuclear magnetic resonance technology. The results showed that the shale bedding structure is the key factor determining the imbibition dynamics and patterns under different boundary conditions.

Summary: There is water in coal pores in the form of adsorption, which can negatively affect coalbed methane production and carbon dioxide storage in coal. Particle size influences water adsorption in coal, with smaller particles having higher rates and amounts of water adsorption. However, the impact of particle size on water adsorption is weaker for high-rank coal compared to low-rank coal. The measurement of water adsorption properties by particles may not be applicable to real coal blocks. Nonetheless, the change in particle size does affect the flow rate of different samples. This study deepens the understanding of water adsorption mechanism in coal with typical particle sizes.

Summary: Coal combustion is a major source of CO2 emissions, but utilizing fly ash to store carbon through the reaction with oxalic acid can mitigate its environmental effects. Our study found that fly ash reacts with oxalic acid to form durable solid oxalate phases, such as whewellite and weddellite. The reaction is relatively rapid, reaching completion within 4 days, and the reacted material contains about 18% Ca oxalate. Based on our calculations, 1 tonne of reacted coal fly ash can store over 34 kg of carbon, with a potential global scale storage of over 35 Mt of carbon per year. Therefore, reacting fly ash with oxalic acid has the potential to reduce the environmental impact of coal burning and can be considered a critical green technology when applied to other alkaline solid wastes.

Summary: This paper proposes a new spontaneous imbibition model based on modifications of the classical Handy model to better predict water imbibition in tight reservoirs. Two important parameters, the average capillary pressure, and the imbibition permeability are derived using a nuclear magnetic resonance spectroscopy method. The model enriches the classical imbibition theory and provides a new approach to analyzing the imbibition of fracturing fluids in complex tight reservoirs.
