A critical review of MXene-based composites in the adsorptive and photocatalysis of hexavalent chromium removal from industrial wastewater.

The growing concern of water pollution is a critical issue stemming from industrialization and urbanization. One of the specific concerns within this broader problem is the toxicity associated with chromium (Cr), especially in its Cr (VI) form. Transition metal carbides/nitrides (MXenes) are attractive materials for the treatment of water due to their unique properties such as layered structure, high surface area, conductivity, flexibility, scalable manufacture, and surface functions.

A highly-selective layer-by-layer membrane modified with polyethylenimine and graphene oxide for vanadium redox flow battery.

The impact of diet and ethnicity on gut microbiota variation in irritable bowel syndrome: A multi-center study.

Background And Aim: The gut microbiota in irritable bowel syndrome (IBS) is known to vary with diet. We aim to (i) analyze the gut microbiota composition of IBS patients from a multi-ethnic population and (ii) explore the impact of a low FODMAP diet on gastrointestinal symptoms and gut microbiota composition among IBS patients.

Methods: A multi-center study of multi-ethnic Asian patients with IBS was conducted in two phases: (i) an initial cross-sectional gut microbiota composition study of IBS patients and healthy controls, followed by (ii) a single-arm 6-week dietary interventional study of the IBS patients alone, exploring clinical and gut microbiota changes.

Improvements in the stability of biodiesel fuels: recent progress and challenges.

Fewer fossil fuel deposits, price volatility, and environmental concerns have intensified biofuel-based studies. Saccharification, gasification, and pyrolysis are some of the potential methods of producing carbohydrate-based fuels, while lipid extraction is the preferred method of producing biodiesel and green diesel. Over the years, multiple studies have attempted to identify an ideal catalyst as well as optimize the abovementioned methods to produce higher yields at a lower cost.

A molecular simulation study on amine-functionalized silica/polysulfone mixed matrix membrane for mixed gas separation.

Polysulfone (PSF) based mixed matrix membranes (MMMs) are one of the most broadly studied polymeric materials used for CO/CH separation. The performance of existing PSF membranes encounters a bottleneck for widespread expansion in industrial applications due to the trade-off amongst permeability and selectivity. Membrane performance has been postulated to be enhanced via functionalization of filler at different weight percentages.

Investigation of transport properties of 6FDA-durene polymeric membrane for landfill gas application using molecular simulation approach.

Gas separation of carbon dioxide (CO) and methane (CH) from landfill gas (LFG) is very crucial to be undertaken to treat significant greenhouse gases (GHG) emitted to the atmosphere. Among the well-developed conventional technologies, membrane has drawn a huge attraction from many researchers to leverage on its application, which favors an efficient and environmentally safe process. In membrane technology, inorganic membrane type requires a complex and pricey fabrication process which is contradictory from the polymeric membrane features.

Enrichment of biogas through composite membrane of PEBA-1657/ hierarchical T-type zeolite.

Presently, composite membranes emerged as a promising approach to overcome the limitations of polymeric and inorganic membranes particularly in acid gas separation. In the present work, composites membranes were fabricated by combining hierarchical T-Type (h-zeolite T) zeolite and PEBA-1657 at different filler composition that ranging from 5 wt% - 30 wt% for the CO/CH separation. The physicochemical properties of the resultant inorganic filler and membranes were investigated by using Brunauer-Emmett- Teller (BET), field emission scanning electron microscopy (FESEM), Fourier Transform infra-red (FTIR), x-ray diffraction (XRD), thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC).

A Review on Recent Progress of Stingless Bee Honey and Its Hydrogel-Based Compound for Wound Care Management.

Performance of Multilayer Composite Hollow Membrane in Separation of CO from CH in Mixed Gas Conditions.

Composite membranes comprising NH-MIL-125(Ti)/PEBAX coated on PDMS/PSf were prepared in this work, and their gas separation performance for high CO feed gas was investigated under various operating circumstances, such as pressure and CO concentration, in mixed gas conditions. The functional groups and morphology of the prepared membranes were characterized by Fourier transform infrared spectroscopy (FTIR) and field emission scanning electron microscopy (FESEM). CO concentration and feed gas pressure were demonstrated to have a considerable impact on the CO and CH permeance, as well as the CO/CH mixed gas selectivity of the resultant membrane.

RSM Modeling and Optimization of CO Separation from High CO Feed Concentration over Functionalized Membrane.

The challenges in developing high CO gas fields are governed by several factors such as reservoir condition, feed gas composition, operational pressure and temperature, and selection of appropriate technologies for bulk CO separation. Thus, in this work, we report an optimization study on the separation of CO from CH at high CO feed concentration over a functionalized mixed matrix membrane using a statistical tool, response surface methodology (RSM) statistical coupled with central composite design (CCD). The functionalized mixed matrix membrane containing NH-MIL-125 (Ti) and 6FDA-durene, fabricated in our previous study, was used to perform the separation performance under three operational parameters, namely, feed pressure, temperature, and CO feed concentration, ranging from 3.

A review on synergistic coexisting pollutants for efficient photocatalytic reaction in wastewater remediation.

With the tremendous development of the economy and industry, the pollution of water is becoming more serious due to the excessive chemical wastes that need to remove thru reduction or oxidation reactions. Simultaneous removal of dual pollutants via photocatalytic redox reaction has been tremendously explored in the last five years due to effective decontamination of pollutants compared to a single pollutants system. In a photocatalysis mechanism, the holes in the valence band can remarkably promote the oxidation of a pollutant.

Obesity among Health-Care Workers: Which Occupations Are at Higher Risk of Being Obese?

Obesity among health-care workers (HCWs) is an important issue as it can affect both their health condition and their professional capability. Although adult obesity is attributable to occupational factors, few reports are available on Malaysian health-care workers' obesity and whether different health-care job categories are related to workers' obesity. This study aimed to determine the prevalence of obesity among HCWs and the association between various HCW job categories and obesity.

Cellulose acetate-based membranes by interfacial engineering and integration of ZIF-62 glass nanoparticles for CO separation.

Composite membranes typically used for gas separation are susceptible to interfacial voids and CO plasticization which adversely affects the gas permeation performance. This paper evaluates routes towards the enhancement of CO permeation performance and CO plasticization resistance of composite membranes using non-stoichiometric ZIF-62 MOF glass and cellulose acetate (CA). Single and mixed gas permeation results, obtained with CO and CH, demonstrate that the presence of ZIF-62 glass in CA polymer enhanced the CO permeability and CO/CH ideal selectivity from 15.
