To date, atomically thin hexagonal boron nitride, covalent organic frameworks, graphene, graphene oxide, transition metal carbides and nitrides, layered double hydroxide, transition metal dichalcogenides (TMDCs), and metal-organic frameworks have been extensively investigated for high-performance lamellar membranes, which is due to their tunable physicochemical properties, single-layered structure, and in-plane pore structure. This comprehensive review summarizes the different fabrication methods of TMDC-based membranes and introduces the recent modification strategies to improve their microstructural properties. TMDCs-based membranes for wastewater treatment, desalination, proton exchange, gas separation, and energy devices are extensively discussed. Finally, we highlight the current engineering hurdles and suggest research directions for improving the separation efficiency, stability, and permeability of these membranes.

Chlorogenic acids are the key components of the phenolic fraction in green coffee seeds, accounting for up to 14% of the dry matter. The manufacturing of decaffeinated coffee demands efficient caffeine extraction from seeds and spent without solvent history effect for safety considerations. This has prompted researchers to investigate eco-friendly and cost-effective extraction technologies. Current extraction processes are not environmentally sustainable and have harmful consequences on humans. To date, developing a single standard method for effective extraction of certain complex compounds from coffee seeds remained a challenging procedure. The current review aims to give updated technical information regarding coffee plant green extraction methods, their advantages and disadvantages, and factors affecting efficacies for the recovery of bioactive compounds in coffee seeds and coffee spent. A comparative review of the uses of innovative green extraction techniques for coffee bioactive substances is introduced to present alternatives to conventional extraction methods. The most interesting finding was that the maximum total extractions of catechin (50.6 g/100 g) and caffeine (46.2 g/100 g) were achieved with enzymes in pressurized liquid extraction (PLE), and PLE-assisted with enzymes exhibited an enhancement in total phenolics and overall antioxidant compared to 50% hydro-ethanolic solutions. In addition, it has been claimed that the ultrasonic extraction can cut extraction time by 37% and temperature by 13%. These green extraction techniques represent favorable approaches to the exploitation of coffee chemicals as bioactives to explore their wide-reaching applications at an industrial level and for their valorization.","PeriodicalId":21744,"journal":{"name":"Separation & Purification Reviews","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84240515","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The success of the treatment process lies on the improved properties of membranes, notably water permeation, solute rejection, and antifouling capabilities. Over the past decade, hyperbranched macromolecules that comprise star polymers and dendrimers have gained increasing attention in membrane research as synthesis materials and modifying agents. These macromolecules which are composed of branched structure, high-density terminal functional groups, and large intramolecular free volume could offer an opportunity to design a new generation membrane with desirable characteristics. This review looks into the recent advances in the polymeric membrane synthesis and its modification using branched macromolecules. Highlights are given to the factors contributing to the changes in membrane properties (structural, morphological, and chemical functional groups) and performance after branched macromolecules are used as main membrane forming material or modifying agent. The review also discusses outlook and future works that can be further explored on utilizing branched macromolecules in membrane application. Challenges in promoting and commercializing branched macromolecules-based membranes are also discussed. This review can serve as a valuable reference for further development of membranes with improved performance and functionalities for water treatment application.","PeriodicalId":21744,"journal":{"name":"Separation & Purification Reviews","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91113107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The thermodynamic properties of impurity components in silicon solutions obtained by both model calculations and experimental measurements are reviewed in detail in this paper with special focus on the infinite dilute activity coefficient and activity interaction coefficient of impurity components in binary Si-i and ternary Si-i-j systems. A positive or negative activity interaction coefficient value can be used to predict a mutually reinforcing or mutually restrictive relationship among impurity components during silicon purification. This review may provide workable guidance to researchers in selecting suitable refining systems and optimized refining conditions for silicon purification according to the thermodynamic properties of the impurity components therein; further, they may be used to establish a silicon solution thermodynamics database to support silicon purification technology.","PeriodicalId":21744,"journal":{"name":"Separation & Purification Reviews","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78789744","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The adoption of stricter requirements for the quality of medicines has resulted in the loss of conformity of some traditional techniques used to prepare TCMs modern pharmaceutical methods. The TCM industry has begun to seek out novel methods to improve product quality and increase economic efficiency. Membrane technology is efficient, energy saving, and environmentally friendly. It is widely used in food processing, desalination, wastewater treatment, and in the medical industry. Membrane technology has also been adopted by the TCM industry as an alternative to traditional technology and has achieved good results. At present, membrane technology has been used in the separation, purification and concentration of TCMs. This review describes the use of microfiltration, ultrafiltration, nanofiltration, reverse osmosis, and membrane distillation, in TCM processing that have been reported.

Phytoextraction of mercury is very challenging due to the specific chemical/biochemical properties of this element and its low plant uptake. In this review, mechanisms and processes of enhancing phytoextraction of mercury are summarized. Plants that look promising for induced phytoextraction of mercury are described. Additives of various types that may significantly increase the efficiency of mercury phytoextraction are critically evaluated. Thiosulfates and other sulfur-containing compounds, aminopolycarboxylic acids, low-molecular-weight organic acids and enzymes are considered in detail. The important role of selective chemical inductors, primarily thiosulfates, is demonstrated. It is shown that synthetic aminopolycarboxylic acids have the potential for increasing bioavailability of mercury in soils and its translocation to above-ground organs of plants-phytoextractors. Non-chemical methods of inducing mercury phytoextraction are also addressed.
