Superhydrophilic PVDF Membrane Modified by Norepinephrine/Acrylic Acid via Self-Assembly for Efficient Separation of an Oil-in-Water Emulsion

With the continuous production of kitchen wastewater, the treatment of oily wastewater has become a worldwide challenge. Here, we propose a novel superhydrophilic poly­(vinylidene fluoride)-g-poly­(norepinephrine) (PVDF-g-PNE) membrane with superhigh water permeability and excellent oil rejection via simple self-assembly. The chemical composition of the modified membrane was successfully confirmed by Fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS) techniques. It was confirmed that the PVDF-g-PNE membrane had both superhydrophilicity and underwater superoleophobicity with a water contact angle (WCA) of 0° and an underwater oil contact angle (UOCA) of 162.8°. Moreover, the PVDF-g-PNE membrane had excellent wetting stability under the environment of acid, alkali, and salt. The PNE coating on the membrane surface showed complete repellency to edible oil and good antiprotein adhesion performance. The prepared membrane possessed an ultrahigh pure water permeability of 32 000 L·m–2·h–1·bar–1. The highest permeability of the prepared membrane was 7348 L·m–2·h–1·bar–1 with an oil rejection of 99.21% when used to treat a surfactant-stabilized edible oil-in-water emulsion. The proposed PVDF-g-PNE membrane was capable of efficiently treating oily wastewater

Fabrication of a Superhydrophilic and Underwater Superoleophobic Membrane via One-Step Strategy for High-Efficiency Semicoking Wastewater Separation

Hydrophilic polyvinylidene fluoride (PVDF) membranes can effectively separate the low oil content in semicoking wastewater. It is important to develop a stable superhydrophilic PVDF membrane with high oil rejection. Here, we developed a one-step strategy based on a polyphenol netlike structure coating to achieve the conversion of commercial membranes from hydrophobic to superhydrophilic; namely, the codeposition of 2-propenamide, N-[2-(3,4-dihydroxyphenyl)­ethyl] (DMA) and 3-aminopropyltriethoxysilane (APTES) in aqueous solution. ATR-FTIR and XPS technologies proved that the coating successfully adhered to the PVDF membrane. The pure water flux of the developed membrane was 17 270 L m–2 h–1 bar–1. When treating simulated semicoking wastewater with low oil content, the permeate flux and the oil content of the filtrate were 5500 L m–2 h–1 bar–1 and –1, respectively. The modified PVDF membrane showed perfect wetting performance. The permeation flux of the real semicoking wastewater cycled 9 times was stable at 4530 L m–2 h–1 bar–1 and the oil content of the filtrate was –1. This work emphasizes a simple way to design superhydrophilic membranes for the separation of low-oil content emulsion, which will be promising for treating semicoking wastewater

Krüppel-Like Factor 6 Rendered Rat Schwann Cell More Sensitive to Apoptosis via Upregulating FAS Expression

<div><p>Krüppel-like factor 6 (KLF6) is a tumor suppressor gene and play a role in the regulation of cell proliferation and apoptosis. After the peripheral nerve injury (PNI), the microenvironment created by surrounding Schwann cells (SCs) is a critical determinant of its regenerative potential. In this study, we examined the effects of KLF6 on SCs responses during PNI. Both KLF6 mRNA and protein expression levels were upregulated in the injured sciatic nerve, and immunofluorescence results showed that many KLF6-positive cells simultaneously expressed the SC markers S-100 and p75NTR. The apoptosis inducers TNFα and cisplatin upregulated KLF6 expression in primary cultured SCs and the SC line RSC96. Although KLF6 overexpression exacerbated cisplatin- and TNFα-induced apoptosis, expression levels of the apoptosis regulators Bcl2 and Bax were not significantly affected in either KLF6-overexpressing or KLF6-depleted RSC96 cells. Realtime PCR arrays and qRT-PCR demonstrated that KLF6 overexpression upregulated four pro-apoptotic genes, FAS, TNF, TNFSF12, and PYCARD, and inhibited expression of the anti-apoptotic IL10 gene expression. Further analysis revealed that FAS protein expression was positively correlated with KLF6 expression in SCs. These data suggest that KLF6 upregulation may render SCs more vulnerable to apoptosis after injury via upregulating FAS expression. </p> </div

Presentation_2_Safety-oriented planning of expressway truck service areas based on driver demand.pdf

The rapid development of the economy has promoted the growth of freight transportation. The truck service areas on expressways, as the main places for truck drivers to rest, play an important role in ensuring the driving safety of trucks. If these service areas are constructed densely or provide a plentiful supply of parking areas, they are costly to construct. However, if the distance between two adjacent truck service areas is very large or the number of truck parking spaces in service areas is small, the supply will fail to meet the parking needs of truck drivers. In this situation, the continuous working time of truck drivers will be longer, and this is likely to cause driver fatigue and even traffic accidents. To address these issues, this paper established a non-linear optimization model for truck service area planning of expressways to optimize truck driving safety. An improved genetic algorithm is proposed to solve the model. A case study of a 215.5-kilometers-length section of the Guang-Kun expressway in China was used to demonstrate the effectiveness of the model and algorithm. As validated by this specific case, the proposed model and solution algorithm can provide an optimal plan for the layout of truck service areas that meet the parking needs of truck drivers while minimizing the service loss rate. The research results of this paper can contribute to the construction of truck service areas and the parking management of trucks on expressways.</p
