Herein, we demonstrate an asymmetric design of the composite polymer electrolyte with two different layers to overcome the interface issues at both the cathode and the anode side simultaneously. At the cathode side, the polypropylene carbonate layer has enough viscosity and flexibility to reduce the inter-facial resistance, while at the Li anode side, the polyethylene oxide layer modified with hexagonal boron nitride has high mechanical strength to suppress the Li dendrite growth. Owing to the synergetic effect between different components, the as-prepared double layer composite polymer electrolyte demonstrates a large electrochemical window of 5.17 V, a high ionic conductivity of 6.1×10-4<\/sup> S/cm, and a transference number of 0.56, featuring excellent ion transport kinetics and good chemical stability.

The as-prepared CoP/CC electrode integrates the advantages of 1D needle-like CoP arrays for efficient electrolyte wettability and fast charge transportation, and 3D CC substrate for superior mechanical stability, flexibility and high conductivity. As a result, the CoP/CC electrode delivers an initial specific capacity of 1283 mAh/g and initial Coulombic effeciencies of 85.4%, which are much higher than that of conventional CoP electrode. Notably, the CoP/CC electrode shows outstanding cycling performance up to 400 cycles at 0.5 A/cm2<\/sup> and excellent rate performance with a discharge capacity of 549 mAh/g even at 5 A/cm2<\/sup>.

A novel n-type conductive polymer binder with excellent electronic and ionic conductivities as well as good adhesion, has been successfully designed and applied for high-performance SiMP anodes in lithium-ion batteries to address this problem. Its unique features are attributed to the strong electron-withdrawing oxadiazole ring structure with sulfonate polar groups. The combination of rigid and flexible components in the polymer ensures its good mechanical strength and ductility, which is beneficial to suppress the expansion and contraction of SiMP s during the charge/discharge process. By fine-tuning the monomer ratio, the conjugation and sulfonation degrees of the polymer can be precisely controlled to regulate its ionic and electronic conductivities, which has been systematically analyzed with the help of an electrochemical test method, filling in the gap on the conductivity measurement of the polymer in the doping state. The experimental results indicate that the cell with the developed n-type polymer binder and SiMP (~0.5 μm) anodes achieves much better cycling performance than traditional non-conductive binders. It has been considered that the initial capacity of the SiMP anode is controlled by the synergetic effect of ionic and electronic conductivity of the binder, and the capacity retention mainly depends on its electronic conductivity when the ionic conductivity is sufficient. It is worth noting that the fundamental research of this work is also applicable to other battery systems using conductive polymers in order to achieve high energy density, broadening their practical applications.","articleNo":"ccl-32-1-203","authorCnList":[],"authorEnList":["Yuanyuan Yu"," Huihui Gao"," Jiadeng Zhu"," Dazhe Li"," Fengxia Wang"," Chunhui Jiang"," Tianhaoyue Zhong"," Shuheng Liang"," Mengjin Jiang"],"authorList":["Yuanyuan Yu"," Huihui Gao"," Jiadeng Zhu"," Dazhe Li"," Fengxia Wang"," Chunhui Jiang"," Tianhaoyue Zhong"," Shuheng Liang"," Mengjin Jiang"],"authors":"Yuanyuan Yu, Huihui Gao, Jiadeng Zhu, Dazhe Li, Fengxia Wang, Chunhui Jiang, Tianhaoyue Zhong, Shuheng Liang, Mengjin Jiang","authorsCn":"","authorsEn":"Yuanyuan Yu, Huihui Gao, Jiadeng Zhu, Dazhe Li, Fengxia Wang, Chunhui Jiang, Tianhaoyue Zhong, Shuheng Liang, Mengjin Jiang","categoryName":"Communication","categoryNameCn":"","categoryNameEn":"Communication","citation":"Yuanyuan Yu, Huihui Gao, Jiadeng Zhu, Dazhe Li, Fengxia Wang, Chunhui Jiang, Tianhaoyue Zhong, Shuheng Liang, Mengjin Jiang.

The controllable screening pressure can be achieved through two approaches, balanced competition by the regulation of protein concentration, and dominant competition by introducing a predatory protein with high concentration. In OPCS process, two proteins were co-incubated with one ssDNA library, and each protein bound its favorable sequences specifically and formed protein-ssDNA complex respectively. Meanwhile, one protein could supply/suffer the picking pressure of affinity and specificity to/from another, which eliminated weakly bound or unbound sequences for each other. Two complexes could be separated and collected conveniently, and aptamers for two proteins obtained synchronously with high affinity and good specificity.

However, it is still a critical challenge to efficiently control ostogenesis and clearly reveal the influence factor. To this end, the fluorescent gold nanodots (Au NDs) with highly negative charges as osteogenic induction reagent are successfully synthesized, which display better than commercial osteogenic induction medium through the investigations of ALP activity (2.5 folds) and cytoskeleton staining (1.5 folds). Two kinds of oligopeptides with different bio-structures (cysteine, Cys and glutathione, GSH) are selected for providing surficial charges on Au NDs. It is revealed that Au-Cys with more negative charges (-51 mV) play better role than Au-GSH (-19 mV) in osteogenic differentiation, when both of them have same size (~2 nm), sphere shape and show similar cell uptake amount. To explore deeply, osteogenesis related signaling pathways are monitored, revealing that the enhancement of osteogenic differentiation was through autophagy signaling pathway triggered by Au-Cys. And the promotion of highly negative charges in osteogenic differentiation was further proved via<\/i> sliver nanodots (Ag NDs, Ag-Cys and Ag-GSH) and carbon nanodots (CDs, Cys-CDs and GSH-CDs). This work indicates part of insights during hBMSCs differentiation and provides a novel strategy in osteogenic differentiation process.","articleNo":"ccl-32-1-266","authorCnList":[],"authorEnList":["Yueqi Zhao"," Lin Meng"," Kai Zhang"," Yuanqing Sun"," Yue Zhao"," Zhe Yang"," Yangliu Lin"," Xinrui Liu"," Hongchen Sun"," Bai Yang"," Quan Lin"],"authorList":["Yueqi Zhao"," Lin Meng"," Kai Zhang"," Yuanqing Sun"," Yue Zhao"," Zhe Yang"," Yangliu Lin"," Xinrui Liu"," Hongchen Sun"," Bai Yang"," Quan Lin"],"authors":"Yueqi Zhao, Lin Meng, Kai Zhang, Yuanqing Sun, Yue Zhao, Zhe Yang, Yangliu Lin, Xinrui Liu, Hongchen Sun, Bai Yang, Quan Lin","authorsCn":"","authorsEn":"Yueqi Zhao, Lin Meng, Kai Zhang, Yuanqing Sun, Yue Zhao, Zhe Yang, Yangliu Lin, Xinrui Liu, Hongchen Sun, Bai Yang, Quan Lin","categoryName":"Communication","categoryNameCn":"","categoryNameEn":"Communication","citation":"Yueqi Zhao, Lin Meng, Kai Zhang, Yuanqing Sun, Yue Zhao, Zhe Yang, Yangliu Lin, Xinrui Liu, Hongchen Sun, Bai Yang, Quan Lin.

Thus, uniform and nanosize MOFs could be prepared within minutes. The obtained MOFs show similar excellent uranium adsorption properties compared with those obtained by other method, with a highly adsorption capability of uranium with 550 mg/g in minutes. The novel MIPEC strategy developed in this work provides an alternative for controllable synthesis of MOFs, and especially has potential application in accelerating traditional organic synthesis.","articleNo":"ccl-32-1-497","authorCnList":[],"authorEnList":["Guoyu Wei"," Yuexiang Lu"," Shuang Liu"," Hongpeng Li"," Xuegang Liu"," Gang Ye"," Jing Chen"],"authorList":["Guoyu Wei"," Yuexiang Lu"," Shuang Liu"," Hongpeng Li"," Xuegang Liu"," Gang Ye"," Jing Chen"],"authors":"Guoyu Wei, Yuexiang Lu, Shuang Liu, Hongpeng Li, Xuegang Liu, Gang Ye, Jing Chen","authorsCn":"","authorsEn":"Guoyu Wei, Yuexiang Lu, Shuang Liu, Hongpeng Li, Xuegang Liu, Gang Ye, Jing Chen","categoryName":"Communication","categoryNameCn":"","categoryNameEn":"Communication","citation":"Guoyu Wei, Yuexiang Lu, Shuang Liu, Hongpeng Li, Xuegang Liu, Gang Ye, Jing Chen.

The anti-corrosion property of graphene coatings were studied through Tafel polarization curves, electrochemical impedance spectroscopy and accelerated corrosion test with extra applied voltage.

Among them, Fe-based materials show remarkable ORR activity, but they are limited by low selectivity and low stability. To address these issues, herein, we have synthesized FeCu-based M-N-C catalysts, inspired by the bimetal center of cytochrome c oxidase (CcO). In acidic media, the selectivity was notably improved compared with Fe-based materials, with peroxide yields less than 1.2% (< 1/3 of the hydrogen peroxide yields of Fe-N-C catalysts). In addition to Cu-N-C catalysts which can catalytically reduce hydrogen peroxide, the reduction current of hydrogen peroxide using FeCu-N-C-20 exceeded that of Fe-N-C by about 6% when the potential was greater than 0.4 V. Furthermore, FeCu-based M-N-C catalysts suffered from only a 15 mV attenuation in their half-wave potentials after 10, 000 cycles of accelerated degradation tests (ADT), while there was a 30 mV negative shift for Fe-N-C. Therefore, we propose that the H2<\/sub>O2<\/sub> released from Fe-Nx<\/sub> sites or N-doped carbon sites would be reduced by adjacent Cu-Nx<\/sub> sites, resulting in low H2<\/sub>O2<\/sub> yields and high stability.","articleNo":"ccl-32-1-506","authorCnList":[],"authorEnList":["Yuemin Wang"," Ergui Luo"," Xian Wang"," Qinglei Meng"," Junjie Ge"," Changpeng Liu"," Wei Xing"],"authorList":["Yuemin Wang"," Ergui Luo"," Xian Wang"," Qinglei Meng"," Junjie Ge"," Changpeng Liu"," Wei Xing"],"authors":"Yuemin Wang, Ergui Luo, Xian Wang, Qinglei Meng, Junjie Ge, Changpeng Liu, Wei Xing","authorsCn":"","authorsEn":"Yuemin Wang, Ergui Luo, Xian Wang, Qinglei Meng, Junjie Ge, Changpeng Liu, Wei Xing","categoryName":"Communication","categoryNameCn":"","categoryNameEn":"Communication","citation":"Yuemin Wang, Ergui Luo, Xian Wang, Qinglei Meng, Junjie Ge, Changpeng Liu, Wei Xing.

In particular, we find that different NLO responses can be observed from GD when dispersed in different solvents, with the strongest NLO response when dispersed in 1-propanol. It is proposed that some intrinsic properties of the solvents, such as the polarity and viscosity, could influence the NLO response of GD materials.

Direct encapsulation of amphiphilic guests by CB[6] and CB[7] can modulate their amphiphilicity, resulting in formation of supramolecular amphiphiles that self-assemble into supramolecular nanoparticles for drug delivery. Additionally, CB[n<\/i>]'s host-guest chemistry on the surface of mesoporous nanoparticles makes CB[n<\/i>] an ideal blocking agent to control drug release from delivery vehicles. These SNDDS possess intrinsic stimuli responsiveness towards external guest or host, which can further incorporate responsiveness to a variety of other stimuli including pH, thermal, redox, photo and enzyme, to realize multiple stimuli-responsive drug release. Moreover, the recent breakthrough in direct functionalization of CB[n<\/i>]s has provided a feasible method for preparing superior CB[6] and CB[7] derivatives that can be employed to build multifunctional SNDDS with unoccupied macrocycles located on surface, which could be decorated with various functional \"tags\" through host-guest chemistry.
