Supercritical fluids offer considerable advantages for the isolation of natural products. Supercritical fluids can be used as antisolvents to precipitate selectively target compounds from a mixture and to remove impurities by the Supercritical Antisolvent technique (SAS). The present decade has experienced a considerable increase in the number of publications that apply this technique to natural extracts, especially for the isolation of polyphenols and carotenoids from plants and microalgae. However, the lack of a clear terminology and purpose adds confusion to the topic. The proposed review aims at defining a research field that consists in applying SAS to natural extracts for the purification of target compounds. To do so, we trace back the origin of the field, discuss the different terminology used to refer to such processes, and suggest appropriate terms for the process and for reported results. This work explores the scope of the topic by compiling all works published to date from a scattered literature, using all possible process terminologies for the search. The information given aims to highlight the most promising applications explored so far and possibly inspire further research.

Forward osmosis (FO) is a membrane-based process that explores the osmotic pressure difference between a feed solution and a draw solution to induce water transport across a semipermeable membrane. Water transport results in the dilution of the draw solution which is reconcentrated using a recovery process. Different from the reverse osmosis process, FO requires lower grade energy and has other advantages, namely, a wide range of applications and a reversible fouling phenomenon of FO membranes. In spite of its many advantages, the FO process is facing drawbacks among which the lack of high-performance membranes. Today, the development of improved FO membranes, capable of achieving a high water flux with a very low reverse salt flux is one of the biggest concerns of membrane scientists. This paper summarizes the basic principle of the FO process, some modern applications, and the main challenges related to membranes. It also describes the progresses in FO membrane development, particularly regarding the membrane manufacturing techniques, commercially available, and R&D membranes.

ABSTRACT Ultraviolet (UV) rays are produced during operation of fluorescent lamps (FLs). Fluorescent coating, also known as phosphor, converts UV rays to visible light. Various chemical compounds, individually or mixed in certain weight ratio, are used as phosphor. Phosphor prepared from rare earth (RE) compounds is energy-efficient. Various components including phosphor are meant to be recycled from FLs once they cease to operate. Review of literatures related to recycling of phosphor suggested that few papers were published prior to 2009. However, there was avalanche of relevant research articles in the next decade. Although RE phosphors were developed in 70s, their use in FLs gained market only after 2009 when energy protection agency passed a resolution to increase the efficiency of the lamps. In the last decade, researchers have done massive work on recycling of phosphor. In the mean time, they switched from one extractive technique to another to overcome the limitations of the former process. In this review, we have investigated the need of switching from one technique to another. We discovered the gaps in these literatures and proposed what needs to be done to fill these gaps. Flow-sheets prepared by compiling the most efficient techniques have been proposed at the end.

ABSTRACT Blood is the most interesting tissue for molecular analysis in a wide range of diseases since it provides accumulative information of the whole body state. Transcriptomic analysis of the blood is one of the most favorable omics approaches for clinical and research purposes. However, blood sample preparation for RNA analyses is highly diverse encompassing specific methodology and application. In this study, we review the common sample preparation maneuvers including RNA handling techniques, sample collection and stabilization, blood cell sorting, extracellular vesicle enrichment, RNA extraction, globin/ribosomal RNA reduction, and RNA concentration and quality assessment. These techniques are the most prevalent procedures of blood sample preparation in RNA transcriptomic analyses. The methodologies, technical challenges of the current approaches, and latest advances in the field are discussed in detail.

ABSTRACT Harmful effects of aqueous metal pollutants and benefits of recycling drive the need for wastewater treatment and recovering metals for reuse. Supported liquid membrane (SLM) separation is one of the potential energy-efficient techniques that can recover metal ions selectively, but improvements in transport rate and stability are needed to improve treatment capacity and SLM lifetime. Many lab studies on SLM could demonstrate metal removal efficiencies above 70% and mass transfer coefficient in the range of 10−6 m/s, but there is more variation in reported SLM stability for different setups tested. Recently, researchers started exploring the use of green chemicals in constructing SLM. In this review, factors affecting selectivity, transport kinetics, and stability of SLMs are presented. Improvement strategies for maturing SLM technique into a technology capable for treating metal-bearing wastewater on an industrial scale are discussed.

ABSTRACT Wastewater remediation technologies are rapidly evolving to meet the increasing water demand. The need to develop efficient, low-cost, and simplistic strategies has motivated researchers to explore newer fields of material science. Owing to high thermal stability, porosity, and accessible functionalities, metal-organic frameworks (MOFs) are finding numerous applications in the domain of wastewater treatment and resource recovery. The application-oriented development of MOFs has been accepted as a novel approach for the removal and recovery of metals from waste solutions. The desired properties in MOFs could be achieved by adopting suitable synthesis or post-synthesis functionalization strategies. Here, we have reviewed differently functionalized MOFs and their application in the removal of metals from waste solutions. We have also discussed the application of MOFs in the pre-concentration and recovery of actinides from seawater. Conclusions regarding the future scope of employing MOFs in the domain of environmental remediation have been included.

Membrane distillation (MD) is a thermally driven membranous process and in the recent years, it has received increasing attention in desalination. Generally, polymeric membranes have dominated the MD studies due to their intrinsic hydrophobic properties and high availability. On the other hand, the development of ceramic membranes for MD desalination is developing, gradually replacing their polymeric counterparts due to superior properties in terms of thermal, chemical and mechanical stabilities, as well as potentially longer service terms. This review describes and evaluates the fabrication methods of ceramic membranes as well as discusses the latest discoveries of ceramic membranes for MD desalination. Despite outstanding properties, the efforts in developing ceramic membranes as a replacement for polymeric membranes in MD desalination are meeting challenges and obstacles; hence, in the last part of this article, the current challenges and future research opportunities of ceramic membrane development will also be addressed.

Electrodeionization (EDI), which combines the advantages of electrodialysis (ED) and conventional ion-exchange (IX) processes, has been successfully applied in the production of ultrapure water. With an ability to perform continuous and deep deionization process without regenerating chemicals, EDI has found a number of new interesting applications such as in wastewater treatment, separation and purification of biotechnology products, and other potential fields. The growing interest has necessitated the development of EDI stack construction and configuration to achieve a better performance. In addition, several studies have been performed to gain a better understanding of ion transfer mechanism in the EDI system. This paper focuses on the mechanism of ionic separation in EDI including the role of ion-exchange resin (IER) and water dissociation reaction as well as its effects on the deionization process. The main technological parameters determining EDI performance are overviewed. Membrane stack configurations along with their advantages and limitation and their development are also pointed out.

Imprinting techniques have been investigated extensively for the selective recognition of molecules and ions. However, few reviews focused on the state-of-the-art developments in ion imprinting technique. Ions and their analogs have a charge and usually similar physical and chemical properties, but less functional groups than molecules. The slight differences in charges, sizes and shapes of ions determine the structure–activity of metal–ligand complexes and imprinted materials. In this review, we focused on the internal connections between each component at coordination and polymerization stages with the affinity and selectivity of the imprinted materials. Advanced imprinting routes such as multiple-template, dual-template docking oriented ionic imprinting and nanocomposite ion imprinted membranes were elaborated. Computational simulation was highlighted for the prediction of functional monomers, binding mechanisms and selectivity. Multiple antifouling enhanced strategies for ion imprinted membranes were put forward to alleviate the trade-off relationship between treated volume and time. The review should provide researchers with new perspectives to explore ion imprinting technology and stimulate more creative breakthroughs in ion separation and purification fields.

ABSTRACT Flavonoids, among the major bioactive ingredients in many traditional Chinese medicines, have been widely considered due to their pharmacological and biochemical effects: antioxidant, anti-vascular disease and anti-inflammatory effects. To get a better understanding of the role of flavonoids in medicine, food safety and public health, valid and sensitive methods for their pretreatment and determination in different matrices are necessary. This review provides a comprehensive summary of flavonoid pretreatment and analytical methods in different samples since 2013. Pretreatment technologies include simple methods: precipitation protein and acid hydrolysis, and more elaborated ones: solid-liquid extraction, liquid-liquid extraction, solid-phase extraction, matrix solid phase dispersion, and different micro-extraction methods. Determination methods include liquid chromatography, gas chromatography, supercritical fluid chromatography, and electrochemical methods. Moreover, we discuss and compare the strengths and weaknesses of the different pretreatment and analytical methods and suggest a prospect.
