Abstract ：
Combining molecular imprinting technology with electrostatic spinning technology, a molecularly imprinted nanofiber membrane material with memory and recognition of specific imprinted molecules is thus produced. It has the advantages of high efficiency, reusability, easy amplification, and simple operation. In this study, alkane molecularly imprinted nanofibrous membranes are prepared as a carrier for immobilize Bacillus cereus LY-1 for the degradation of diesel in oil-water system. The adsorption capacity of the molecularly imprinted material for diesel oil with n-decyl alcohol as the template molecule reach 120.25 mg g-1, the adsorption capacity of alkane molecularly imprint nanofiber membrane prepared using polyvinyl alcohol (PVA) as the membrane substrate material is 41.37 mg g-1. After 4 days, the immobilized LY-1 cells eliminate roughly 80.7% of the diesel at a starting concentration of 3 g L-1. The results show that imprinted structures in MINM enhance degradation by loaded microorganisms.

Abstract ：
Sodium lignosulfonate amine (SLA) was synthesized by Mannich reaction. The lignin-modified waterborne polyurethane (WPU) with different branched structures was designed and prepared by introducing SLA as a hydrophilic chain extender. The effect of the introduction manner of SLA on the performance of WPU was systematically investigated. The results showed that the addition of 0.75 wt% SLA in an appropriate introduction manner can prepare a polyurethane dispersion with good stability and high solid content. The tensile strength of the SLA-modified WPU film was significantly improved to 37.3 MPa. The SLA-modified WPU film also exhibited high water resistance and thermal stability. Moreover, in the introduction manner of WPU-C, the adhesive properties of SLA-modified WPU adhesives were also improved, which was mainly attributed to the entanglement of long branched chains generated by SLA chain extension with other polyurethane chains and the formation of physically cross-linked networks through the interaction between functional groups. Therefore, the introduction of a small amount of sodium lignosulfonate amine in an appropriate manner can significantly improve the performance of WPU with high solid content, which provides a new way to prepare highperformance waterborne polyurethane.

Abstract ：
Oil pollution from the petroleum industry is a growing problem, especially in terms of the harm it causes to the aquatic environment, which puts humans and other aquatic life in grave danger. As immobilized carriers for the removal of diesel, thermoplastic polyurethane (TPU) nanofiber membranes and co-blended nano-hydroxyapatite modified thermoplastic polyurethane (TPU/nHA) nanofiber membranes are reasonably priced, non-toxic, and non-polluting. The adhesion and colonization of the bacterial cells to these carriers were studied using scanning electron microscopy (SEM). Gas chromatography was used to measure the bioremediation effectiveness, and the results after 3 days of remediation revealed a substantial improvement in the removal of hydrocarbons by immobilization compared to free bacteria. With an initial concentration of 3 g/L diesel, the TPU/1.5HA-bacteria system enhanced the removal of diesel the most (20.64 +/- 0.40%), followed by TPU/1HA-bacteria (17.49 +/- 0.08%), TPU/0.5HA-bacteria (11.97 +/- 0.40%), and TPU-bacteria (4.69 +/- 0.13%), in that order. Within three days, these scaffolders had completely absorbed the spilled diesel. There haven't been any studies done yet on the removal of diesel using various carriers loaded with Bacillus altitudinis LS-1. This study demonstrated that TPU-based electrostatic spinning films can be used as bio-carriers for hydrocarbon-degrading bacteria, enhancing the bioremediation of oil-contaminated water.

Abstract ：
Microbial fuel cells (MFCs) are a potential biotechnology for simultaneous degradation of organic wastewater and power generation. In this paper, a biocompatible composite is constructed around a copper mesh with sodium alginate/agar and activated carbon (CM-SA/AC) and acts as an efficient anode for MFCs after being microbe immobilized. The power performance of the MFC with CM-SA/AC anode is investigated. The results show that the addition of activated carbon is conducive to the immobilization of bacteria on CM-SA/AC anode and fast start-up of MFCs. The power density reaches 1088.6 mW/m(2), which is 2.03 times and 1.75 times that of CM-SA (without activated carbon) anode and carbon felt anode, respectively. In case of a candied wastewater treatment, the MFC with immobilized CM-SA/AC anode exhibits a much higher power density (724.5 mW/m(2)) than that with carbon felt anode (145.0 mW/m(2)), together with a longer stabilization time and a smaller charge-transfer resistance. The total removal rate of chemical oxygen demand (COD) reaches 79.4 +/- 0.65%. The present study will facilitate the development of inexpensive and biocompatible anodes to facilitate the application of MFCs in wastewater treatment.

Abstract ：
A strain of Lysinibacillus sp., named as Y316, can degrade heavy fractions such as resins and asphaltenes in oil sand. We used Y316 to degrade oil sand samples for 35 days. After bacterial degradation, the oil sand degradation efficiency was 5.88%, while the degradation efficiency of the control group was only 0.29% under the same conditions. Compared with the control group, the saturated content of oil sand in the degradation group increased from 9.56 to 14.39%. After degradation, the resin and asphaltene fractions decreased by 5.34 and 4.77%, respectively. The results of the vaporizable fraction analysis also confirmed the degradation of heavy fractions and the formation of light fractions. After 35 days of degradation, the vaporizable fractions of saturates increased by 3.76 times. The results indicate that Y316 has great significance for improving the quality of oil sands and assisting in oil sand exploitation.

Abstract ：
Nanofiber membranes have recently been considered as promising supports for the immobilization of microorganisms due to the simplicity and cost-effectiveness of electrostatic spinning technology and the ability to control fiber morphology, such as obtaining higher surface area and porosity. In this study, electrospun polyvinyl alcohol/sodium alginate/attapulgite (PVA/SA/ATP) nanofiber membrane was prepared as support for immobilized Bacillus cereus LY-1 for diesel degradation in an aqueous medium and a significant improvement in diesel removal efficiency was realized. The effect of modified ATP concentration on diesel removal was investigated. The results showed that the nanofiber membranes complexed with cetyl trimethyl ammonium bromide (CTAB) and 1% ATP (w/w) had the best capacity for diesel removing. When the initial diesel concentration was 2 g L-1, about 87.8% of diesel was removed by the immobilized LY-1 cells after 72 h. Immobilization of bacteria improves the ability of bacteria to survive in adverse environments. Immobilized LY-1 cells maintain the nature to remove diesel at high salinity or pH range of 6-9. Furthermore, the reusability of the LY-1 cells-immobilized PVA/SA/CTAB-ATP nanofiber membrane was tested. A diesel removal rate of 64.9% could be achieved after 4 times of use. PVA/SA/CTAB-ATP nanofibrous membranes with immobilized LY-1 cells are feasible, economical and environmentally friendly for remediation of diesel contamination in the aqueous medium, and have potential applications in the future.

Abstract ：
Bacillus cereus LY-1 is isolated from Indonesian oil sand with oil-sand oil as the only carbon source, and the surfactant secreted by bacteria is identified as lipopeptides. GC and GC-MS were used to study diesel oil degradation by B. cereus LY-1. GC-MS and the improved B-L method were used to study the changes in oil-sand oil composition and structural parameters due to bacterial degradation. The results of GC-MS show that the main volatile components of diesel oil are C11-C14 at 40celcius, and B. cereus LY-1 has higher degradation efficiency for saturated alkanes and normal alkanes with high carbon number (C15-C24). In the experiment of degrading oil-sand oil, the four results of components show the resin in the treated oil-sand oil is reduced from 60.41 +/- 1.03% to 55.03 +/- 0.39%, the aromatic fraction increased from 21.04 +/- 1.09% to 23.42 +/- 0.7%, and the saturated hydrocarbon fraction increased from 17.59 +/- 2.08% to 21.55 +/- 0.44%. The results of GC-MS show that after B. cereus LY-1 treatment, long-chain saturated alkanes, aromatics, and complex aromatics can be utilized by B. cereus LY-1, and some relatively simple complex molecules are produced. The structure of oil-sand oil that became loose further illustrates this. The oil components of oil-sand oil are converted to light components, and B. cereus LY-1 has the ability to convert complex petroleum hydrocarbons into relatively simple fatty hydrocarbons.

Abstract ：
As the core component of wearable electronic devices, flexible energy storage materials play an irreplaceable role. At present, it is still a challenge to prepare flexible electrode materials with high energy density. In this paper, a polyaniline-based composite flexible conductive hydrogel (PPG-P) with a two-level conductive network is successfully prepared by a secondary induced assembly in situ polymerization method. The special conductive structure greatly promotes the efficiency of charge transfer and the utilization of electroactive substances, so that PPG-P exhibits excellent electrochemical performance. In a three-electrode system, PPG-P has a mass-specific capacitance as high as 989 F g(-1) (0.5 A g(-1)). After 1000 charge and discharge cycles, the capacitance retention is 87%. Symmetrical flexible supercapacitors based on PPG-P have high specific capacitance (176 F g(-1)/0.5 A g(-1)) and high energy density (15.6 Wh kg(-1)). After 1000 cycles of constant current charge and discharge, the capacitance maintains 78.1%. The preparation of PPG-P with a hierarchical structure demonstrates the possibility of achieving high energy density in flexible electrode materials, which has great application potential in the development of energy storage elements in wearable devices.

Abstract ：
An imprinted electrospun fiber membrane was developed for the detection of volatile organic acids, which are key components of human body odor. In this study, hexanoic acid (HA) was selected as the target, polymethyl methacrylate (PMMA) was used as the substrate, and colorimetric detection of HA was achieved by a bromocresol purple (BCP) chromogenic agent. The results showed that the morphology of the fiber membrane was uniform and continuous, and it showed excellent selectivity and specificity to HA. Photographs of the color changes before and after fiber membrane adsorption were recorded by a camera and quantified by ImageJ software by the difference in gray value (Delta Gray). This method is simple, intuitive, and low cost and has great potential for application in human odor analysis.
