The development of a new crude oil emulsion demulsifier to replace the block polyether has always attracted attention. In this article, a novel crude oil emulsion demulsifier was prepared by dispersion polymerization using a mixture of ether and water as the dispersion medium and acrylate, methacryloxyethylthrimethyl ammonium chloride (DMC), and acrylamide as the comonomers. Taking the stability and demulsification performance as the index, the effects of acrylate type, ether/water mass ratio, monomer mass ratio, monomer concentration, initiator type, ether type, and reaction temperature on the polymerization results were investigated. The experimental results showed that when the acrylate was butyl acrylate (BA), the mass ratio of BA to DMC was 1:1, and dispersion medium was the mixture of dipropylene glycol methyl ether and water (ether/water mass ratio 1.5:1), monomer concentration was 20 wt%, initiator was V50, reaction temperature was in range of 50 to 55 C, and polymerization reaction was 10 h, the product P (BA-DMC-AM) had a good demulsification performance for the crude oil emulsion (crude oil density 0.9625 g/cm 3 , water

“…In recent years, although clean energy, such as solar energy, wind energy, hydrogen energy, and ocean energy has attracted more and more attention, [1][2][3][4] traditional fossil energy still plays a very important role in modern industry. Therefore, the exploration and development of crude oil is still important.…”

Electrospinning is a facile technique to create porous nanofiber scaffolds with a high capability of natural environment mimicking. Here, co‐electrospinning of gelatin:TiO2, polycaprolactone:silk fibroin (G:T/P:F) was investigated with the aim of wound healing. Polycaprolactone improved the mechanical properties and gelatin:TiO2 enhanced cellular interactions. Silk fibroin was extracted from the Bombyx mori silkworm and increased the cellular and mechanical properties of the designed scaffolds. The morphology of the scaffolds was observed with field emission scanning electron microscopy (FESEM) and confirmed bead free porous nanofibrous structure. The fiber diameter rose after silk fibroin and TiO2 addition but it was in the favorable fiber range. The contact angle, swelling, and mechanical properties of the G:T/P:F scaffolds supplied the requirements for skin tissue engineering. The designed scaffold showed over 80% cell viability with filopodia formation after 48 h according to cell adhesion observations and MTT assay results. The DAPI and LIVE/DEAD staining results confirmed high cell viability and the scratch assay observations proved the high wound healing potential of the G:T/P:F scaffolds. Furthermore, antibacterial properties were shown. It seems the designed scaffold can be useful in skin tissue regeneration. Further research may address the suggested skin scaffold.

“…Groundwater is a significant natural water supply for residential, agricultural, and industrial usage and is utilized as a commodity worldwide (Green, 2016 ; WWDR, 2015 ). Water pollution has become a severe ecological concern due to several organic and inorganic pollutants created by commercial, agricultural, and industrial textiles, leather, pharmaceutical, and other industries (Yousefi et al, 2017 , 2019a , 2019b , 2021a ). Groundwater is divided into different portions world across the globe, with 65 per cent being used for drinking water, 20 per cent for animal feeding and farming, and 15 per cent for industrial and mining uses (Adimalla & Qian, 2020 ; Saeid et al, 2018 ; Yousefi et al, 2021b , 2021c ).…”

Groundwater pollution of the watershed is mainly influenced by the multifaceted interactions of natural and anthropogenic process. To analyse the spatial–temporal variation and pollution source identification and apportionment, the dataset was subjected to a globally acknowledged coherent technique using water quality indices and chemometric techniques (principal component analysis (PCA) and cluster analysis. The bulk of the samples tested were below the BIS’s permissible levels. Groundwater samples from the pre- and post-monsoon seasons mostly contained the anions HCO − 3 > Cl − > SO 2− 4 > NO − 3 , while the primary cations were Ca 2+ > Mg 2+ > Na + > K + . Groundwater was alkaline and hard at most of the sites. According to hydro-geochemical facies and relationships, Piper diagrams, and principal component analysis, weathering, dissolution, leaching, ion exchange, and evaporation were the key mechanisms influencing groundwater quality. The hydrochemical facies classified the groundwater samples into the Ca-Mg-HCO 3 type. For all the sampling locations, PIG was determined to be 0.43, 0.52, 0.47, 0.48, 1.00, and 0.70; respectively. The majority of the test locations fell into the low to medium contamination zone, as determined by the groundwater pollution index (PIG) and contamination index. Three principal components, which together account for 93.8% of the total variance, were identified via PCA. The study’s findings confirm the value of these statistical techniques in interpreting and understanding large datasets and offering reliable information to reduce the time and expense of programmes for monitoring and evaluating water quality.
