This study explores the economic, energetic, exergy efficiency, and environmental benefits of energy integration in pressure-swing distillation, focusing on the separation of tetrahydrofuran/water and acetone/chloroform azeotropes. Heat integration and heat pump techniques are applied to reduce energy consumption. Three energy-efficient configurations are examined, comparing total annual cost (TAC), total energy consumption (TEC), CO₂ emissions, and second-law efficiency. In the tetrahydrofuran/water system, heat integration and heat pump technologies outperform conventional processes, achieving up to 50.2% TAC reduction, 59.6% TEC reduction, 82.8% CO₂ emission reduction, and thermodynamic efficiencies up to 23.5%. In the acetone/chloroform system, similar improvements are observed, with up to 70.9% TAC reduction, 87.2% CO₂ emission reduction, and thermodynamic efficiencies up to 17.6%. These findings demonstrate the effectiveness of energy-saving strategies, endorsing process intensification for environmentally sustainable azeotropic mixture separations. © 2024 The Author(s)

Photoreduction CO 2 to value-added fuels (CO, CH 4 , etc.) driven by solar energy gives a green way for managing the global carbon balance. Through the radio-frequency thermal plasma treatment, fiber-like structured ZnO with rich oxygen defects were successfully designed and synthesized. The inherent one-dimensional structure enabled itself avoid aggregation during performance evolution within the humid environment and shorten the transfer path length of the photo-induced carriers and promote more electron/hole to migration to the surface of the photocatalyst. Besides, the rich oxygen vacancies could not only hinder the recombination of photo-generated electron/hole pairs, but also broaden the light absorption spectrum. Therefore, when applied in CO 2 photoreduction, the optimal fiber-like ZnO with rich oxygen defects catalyst behaved outstanding photocatalytic performance with a CO 2 -to-CO rate of 15.84 μmol g - 1 h - 1 . © 2022, The Authors.

引用

Indoor Air 2025年第1期2025卷

作者： Stephan Puntigam Stefan Radl Peter Karlinger Centre for Research Development and Transfer Rosenheim Technical University of Applied Sciences Rosenheim Germany Institute of Process and Particle Engineering Graz University of Technology Graz Austria tugraz.at

We provide a systematic review of the literature on computational fluid dynamics (CFD) in the cleanroom sector. The objective is to provide simulation engineers with an overview of studies in the field of cleanroom simulation, as well as to identify the most commonly used simulation parameters. Our findings indicate a persistent preference for the k − ε model for turbulent flow situations, although recent studies suggest a shift toward more sophisticated models, such as the RNG k − ε and SST k − ω . This reflects advancements in the available computational power made in the past years. Our analysis of particle tracking models indicates a clear preference for the Euler–Lagrange method over the Euler–Euler method. Moreover, the analysis of inlet models used indicates that geometrically resolved diffusers are preferred over simplified models. As every simulation study requires proper validation, full-scale experiments are clearly preferred in the reviewed studies. A best practice guide is distilled out of previous studies to provide a meaningful starting point for future CFD studies in the cleanroom sector.

Robusta coffee, a vital cash crop for Vietnamese smallholders, significantly contributes to the national economy. Vietnam is the largest exporter of Robusta coffee, supplying 53% of the global market. However, this success has come at a cost. Decades of intensive Robusta coffee cultivation in Vietnam have led to severe soil acidification and biodiversity loss, favoring soil-borne pathogens. There is a lack of literature analyzing how intensive management causes soil acidification, advances the spread of soilborne pathogens, and the application of soil amendments to address these issues. Therefore, this review explores the causes of acidification, pathogen proliferation, and sustainable amendments like lime and biochar to mitigate these effects. The study synthesizes findings from studies on soil acidification, soil-borne pathogen dynamics, and sustainable soil amendments in Robusta coffee systems. We found that the overuse of nitrogen-based chemical fertilizers to grow coffee is the primary driver of soil acidification, consequently increasing soilborne diseases and the severity of plant diseases. Additionally, the effects of soil amendments as a sustainable solution to reduce soil acidity, enhance soil health, and better control soilborne pathogens. The implementation of sustainable coffee farming systems is strongly recommended to meet the increased demand for safe and green products worldwide. Locally available resources (lime, biochar, and agricultural wastes) present immediate solutions, but urgent action is required to prevent irreversible damage. However, the effects of amendments significantly vary in field conditions, suggesting that further studies should be conducted to address these challenges and promote sustainability.

This overview addresses the formation of solid trash and the various forms of waste from a variety of industries, which environmentalists have embraced. The paper investigates the negative effects on the environment caused by unsustainable management of municipal solid trash as well as the opportunities presented by the formal system. This examination looks at the origins of solid waste as well as the typical treatment methods. Pyrolysis methods, feedstock pyrolysis, and lignocellulosic biomass pyrolysis were highlighted. Explain in detail the various thermochemical processes that take place during the pyrolysis of biomass. Due to its carbon content, low cost, accessibility, ubiquitousness, renewable nature, and environmental friendliness, biomass waste is a unique biochar precursor. This study looks at the different types of biomass waste that are available for treating wastewater. This study discussed a wide variety of reactors. Adsorption is the standard method that is used the most frequently to remove hazardous organic, dye, and inorganic pollutants from wastewater. These pollutants cause damage to the environment and water supplies, thus it is important to remove them. Adsorption is both simple and inexpensive to utilize. Temperature-dependent conversions explain the kinetic theories of biomaterial biochemical degradation. This article presents a review that explains how pyrolytic breakdown char materials can be used to reduce pollution and improve environmental management. © 2023 Elsevier Ltd

Bone tissue engineering (BTE) has attained enough attention towards fabricating a scaffold for the treatment of bone injury. To develop an ideal scaffold, various techniques and polymers have been explored. Electrospinning has been much focused on fabricating a scaffold by taking various polymers for bone tissue engineering in recent years. In this study, a tri-polymer (PCL-gelatin-chitosan;PCL-GT-CS) scaffold was first fabricated through electrospinning. Then, the surface of the fabricated scaffold was treated with 1 wt% of nanohydroxyapatite (nHAp) for 10, 20 and 30 minutes. After treatment, nHAp modified PCL-GT-CS nanofibrous scaffold was studied by field emission scanning electron microscopy (FE-SEM) to investigate the surface morphology, fiber diameter and pore size. FE-SEM analysis revealed a uniform distribution of nHAp particles on the surface of nanofibers in PCL-GT-CS scaffold after 20 minutes. The fiber diameter and pore size of nHAp treated scaffold (20 minutes) were determined and found to be 680 ± 184 nm and 5.3 ± 2.1 µm respectively. Further, X-ray diffraction (XRD), Energy dispersive X-ray spectroscopy (EDS), Fourier transform infrared (FT-IR) spectroscopy, thermogravimetric (TG) and derivative thermogravimetric analysis (DTG) suggested the presence of nHAp over the surface of PCL-GT-CS nanofibrous scaffold. The cell viability of human osteoblasts over the nHAp modified PCL-GT-CS scaffold was analyzed by MTT assay which was found higher than the unmodified (PCL-GT-CS) scaffold. Furthermore, DNA quantification was performed to examine the proliferation of osteoblasts which was also found significantly higher on nHAp modified scaffold than the unmodified scaffold. Moreover, FE-SEM analysis of the scaffold, seeded with cell, depicted effective cell attachment of osteoblasts, well-spread morphology with their characteristic polygonal shape over the modified PCL-GT-CS nanofibrous scaffold. Thus, in-vitro study of nHAp modified PCL-GT-CS nanofibrous scaffo

The vaginal microbiome, typically dominated by Lactobacillus species, plays a key role in reducing the risk of preterm birth (PTB) by protecting against infections. In this study, we sequenced 133 Lactobacillus genomes isolated from the reproductive tracts of pregnant Indian women. Genomic analysis identified genes linked to pathogen resistance and anti-inflammatory functions. Further proteome analysis of cell-free supernatant revealed antimicrobial properties, including lysin and bacteriocin, while antibacterial tests confirmed their ability to inhibit reproductive tract pathogens. These findings suggest that Lactobacillus strains protect against harmful microbes, potentially reducing infection risks and PTB. This Lactobacillus consortium holds promise for developing biotherapeutics aimed at improving maternal health. © 2025

This paper presents the thermodynamic analysis, performance assessment and working fluid selection for a novel integrated vapor compression cycle and the organic Rankine cycle system, which recovers ultra-low-temperature waste heat (50 °C) rejected by the condenser of a vapor compression cycle (VCC). The study is conducted on a vapor compression system of a 35 kW cooling capacity, followed by the component sizing of the organic Rankine cycle (ORC) based on the available waste heat in the condenser of the refrigeration system. The effect of the operational parameters of the vapor compression cycle on the overall system performance are investigated. The system performance of the integrated system is estimated in terms of coefficient of performance, cycle thermal efficiency and exergy efficiency. The novel integrated systems has been analyzed thermodynamically for 36 pairs of pure refrigerants. Results show that the working fluid pair R600a/R141b with combined coefficient of performance (3.54), ORC thermal efficiency (3.05 %), electricity saving ratio (13.34 %) and total exergy destruction (6.94 kW) is the most suitable VCC/ORC working fluid pair in full condensing method. R407c-R141b is found to be the best working fluid pair in desuperheating method for the same integrated system. The performance analysis for full condensation and desuperheating methods are also investigated. The results indicate a 12.5 % improvement in the coefficient of performance of the integrated system using the full condensation method and a 2.5 % improvement using the desuperheating method compared to the standalone air conditioning system. Additionally, the sensitivity analysis results show that there exists optimum operating condition that maximize the system performance of the integrated system. © 2024 The Author(s)
