Summary: A new flash tank-assisted single-column extractive distillation with heavy entrainer (FT-SCED) is proposed in this paper, which can achieve high-purity light and heavy products from the overheads of column and flash tank, respectively. Two case studies show that the proposed process has lower annual total cost compared with conventional extractive distillation and extractive dividing wall column.

Summary: The study discusses the process of salt rectification for separating liquid mixtures, using an organic imidazolinium salt for the first time. By studying the liquid-vapor equilibrium, it was found that the azeotrope can be broken at an imidazolinium salt concentration of 0.1 mol kg(-1). The NRTL electrolyte model is used to describe the vapor-liquid equilibrium in the ternary system.

Summary: This study introduces a novel method called SPADIS, which favors selecting remotely located SNPs to account for their complementary effects in explaining a phenotype. Compared to the state-of-the-art method SConES, SPADIS shows better phenotype prediction performance, consistently improving across multiple networks and settings, identifying more candidate genes, and running faster.

Summary: This study investigates the use of quinolinium salt as a separating agent for double azeotropic mixtures in extractive distillation. Gas chromatography is used to analyze the liquid-vapor equilibrium in a methanol-benzene-chloride N-benzylquinolinium system at different concentrations of organic salt. The study establishes that a concentration of 0.25 or higher is required to break the azeotrope and separate the mixed solvent into its components.

Summary: This study investigates the properties and vapor liquid equilibrium (VLE) of two binary mixtures, R1243zf + R1234yf and R1243zf + R245cb, which could be potential long-term alternative refrigerants for heat pumps. The critical properties and VLE were determined through experiments and modeling. The results show that these mixtures exhibit good performance at high temperatures.

Summary: This study proposes a novel eco-friendly method to achieve efficient and stable solid amine adsorbents. A calcium silicate hydrate (CSH) support with high pore volume is synthesized from coal fly ash (CFA) and then PEI@CSH adsorbents are prepared. The adsorbent exhibits high adsorption capacity, excellent cyclic stability, and low cost, making it applicable for CO2 mitigation in coal-fired power plants.

Summary: The study found that the B consortium had the best crude oil degradation effectiveness in both in-vitro and soil environments, with a removal effectiveness ranking of B>A>C. In the experiments, the B consortium not only showed higher removal efficiency for crude oil aliphatic and aromatic hydrocarbons but also degraded a wider range of alkane chains. However, interactions between different components may affect the degradation efficiency.

Summary: Urban forests play a critical role in providing environmental benefits, but the challenge of low species diversity in urban forest management remains. This study in central Florida tested underutilized native tree species and found that Ulmus alata and Viburnum obovatum showed the greatest potential in urban settings. The project also showed that co-production of knowledge involving local municipalities, practitioners, and researchers is an effective strategy for selecting and testing underutilized tree species.

Summary: In 2014, Linger et al. proposed a tandem process that combines chemical and biological catalysis for lignin valorization. Chemical pretreatment of corn stover produced mixed lignocellulose-derived monomers, which were further converted to a single product, polyhydroxyalkanoates, by Pseudomonas putida. Since then, tandem processes have been developed for various feedstocks to promote the bioeconomy.

Summary: The study demonstrates that key factors driving acute aquatic toxicity include lipophilicity, electrophilic reactivity, molecular polarizability, and size. Local models, trained on homogeneous data sets, show less errors and are superior to the global models. Despite worse performance metrics, global models have a wider applicability domain, making them more useful in practical regulatory applications.

Summary: Despite the flammability and explosiveness of R290, these disadvantages can be addressed by adding flame-retardant R1234ze(E) to create a refrigerant mixture known as RC01, which has better thermodynamic and thermophysical properties compared to R22. With an ozone depletion potential of 0 and a global warming potential of 12, RC01 is a near-azeotropic refrigerant with low flammability and good lubrication properties, making it technically feasible to replace R22.
