However, the SiOx/C electrode exhibits large volume expansion and unstable SEI layer formation during cycling. In this work, a carbon tetrafluoride (CF) plasma was used to introduce C-F bonds onto the electrode surface to form a LiF-based SEI layer on a SiOx/C electrode (SGE) to improve its mechanical and electrochemical properties. The fluorinated SiOx/C electrode (FSGE) subjected to the CF plasma treatment for 10 min mitigated 2.5 times the volume expansion compared to the SGE by forming a LiF-based SEI layer to increase the mechanical properties. This mitigation of FSGE volume expansion resulted in excellent long-term cycling stability of 83 % for 100 cycles (1C). In addition, the LiF-based SEI layer formed on the FSGE increased the mobility of Li ions, resulting in 1.2 times better cycle stability than that of SGE at a high rate (10C). Thus, the improvement in the electrochemical performance achieved by reducing the volume expansion of SiOx in the electrode and enhancing the Li-ion conductivity was attributed to the stable LiF SEI layer formed with semi-ionic CF bonds introduced by the CF plasma.","PeriodicalId":363,"journal":{"name":"Journal of Industrial and Engineering Chemistry","volume":"17 1","pages":""},"PeriodicalIF":6.1,"publicationDate":"2024-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142211199","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, the viability of the pilot-scale application of this technology for desalination was tested, and the process performance was evaluated in terms of distillate flow rate, salinity removal, and energy consumption, considering different experimental conditions. Synthetic solutions containing 10.0 and 35.0 g/L of sodium chloride were used to simulate brackish water and seawater salinities, respectively. The thermal desalination pilot plant integrating a compact falling film distillation column and a biphasic thermosyphon demonstrated high effectiveness, consistently producing desalinated water with a conductivity below 10 μS cm. Considering both concentrations, the optimal condition for desalinated water production was a feed temperature of 85 °C, a vapor chamber temperature of 121 °C, and an energy consumption of 16 kW. This new technological option’s energy consumption is approximately 33 % lower than that of a simulated flash distillation column operating under similar conditions. In conclusion, this study presents promising results, establishing falling film distillation technology as a viable alternative for desalinating brackish water and seawater.","PeriodicalId":363,"journal":{"name":"Journal of Industrial and Engineering Chemistry","volume":"3 1","pages":""},"PeriodicalIF":6.1,"publicationDate":"2024-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142211203","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results indicated that the prepared CuS and ZnS quantum dots have small sizes with values of 13.8 and 8.9 nm, respectively. Compared to the pure EP coating, QD-EP coatings have a higher mechanical strength and toughness which is conducive to improving the coatings’ corrosion resistance and service life. The impedance values of all the QD-EP coatings increase by more than three orders of magnitude in contrast to pure EP coating after 60 d of testing.

The utilization of microfluidic reactors for PI has transformed various industries by enabling efficient handling of reactions and precise control of operating conditions, by advantages encompassing the reduced consumption of samples, reactants and catalysts, enhancement of heat and mass transfer rates, inherent from the high surface area to volume ratio. Despite the advances in the field, challenges remain, particularly concerning the manufacturing costs associated with scale-up and numbering-up, especially in catalytic processes. Effectively transitioning from microscale to industrial-scale production demands careful Research and Development (R&D) and innovative strategies to preserve the enhanced mixing and reaction capabilities inherent to microscale technologies. The scale-up of catalytic processes using microfluidic-based devices introduces distinct challenges, including managing heat transfer and ensuring optimal flow distribution. This review addressed promising developments in critical strategies to overcoming these challenges, such as the optimization of reactor block and flow distributors that can be initially performed by Computational Fluid Dynamics (CFD). Moreover, achieving effective thermal management in microreactor systems necessitates a balance between heat removal from reactors and minimizing heat dissipation into the surroundings. Innovative techniques such as 3D printing for customizable designs, coupled with numerical simulations to refine geometries, play fundamental roles in overcoming these challenges. MRT alongside innovation in the catalyst field holds great potential in the application of microfluidic-based devices in PI of catalytic processes and can contribute significantly for more sustainable processes.","PeriodicalId":363,"journal":{"name":"Journal of Industrial and Engineering Chemistry","volume":"80 1","pages":""},"PeriodicalIF":6.1,"publicationDate":"2024-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142211246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Large volumes of solid waste are generated during the processing of dairy wastewater, known as dairy processing sludge (DPS). Organic and inorganic chemicals, carbon, nitrogen, phosphorus, chlorides, sulfides, fats, oils, and grease comprise most of the DPS. Discharging untreated DPS into surrounding water sources harms the environment because of its elevated organic contents. Alternatively, the DPS can potentially be transformed into struvite, char, and ash with some fertilizer equivalence values. DPS contains heavy metals, pathogens, and synthetic organic compounds (hormones and pesticides) and requires pretreatment before its direct application as a fertilizer equivalent. DPS can be effectively treated by non-conventional methods, such as earthworms converting it into nutrient-rich fertilizer. Moreover, circular economy principles can be fulfilled by recycling DPS into value-added products, such as bacterial growth media for rhizobia, stabilizing contaminated soil for growing biofuel plants (e.g., ), and further used as a potential substrate for biodiesel production. This review elucidates the generation, composition, treatments, and opportunities for reusing DPS in a sustainable and eco-friendly manner that minimizes environmental pollution and identifies important future research prospects.","PeriodicalId":363,"journal":{"name":"Journal of Industrial and Engineering Chemistry","volume":"6 1","pages":""},"PeriodicalIF":6.1,"publicationDate":"2024-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142227913","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
