Accelerating the breaking of the nitrogen nonpolar bond(N≡N)is an important factor to improve the effi ciency of the electro-catalytic nitrogen reduction reaction(e-NRR).In this work,polyoxometalates-derived FeMo-based ternary oxide materials MoO_(2)-Mo_(4)O_(11)-FeMoO_(4)@X(abbreviated as MoFeO@X,X represents the synthesis temperature of 650,750 and 850℃)were designed and synthesized for e-NRR under ambient *** scanning electron microscopy images of MoFeO@750 show an ellipsoidal-like structure(0.86×0.6μm).The relatively large specifi c surface area,formation of multiple interfaces,together with the synergistic eff ect of iron and molybdenum bimetals,would make MoFeO@X catalyst more easily absorb and activate N_(2)in the ***,the synthesized MoFeO@750 shows an optimal NH_(3)production rate of 16.57μg·h^(−1)·mg cat.^(−1)and Faradaic effi ciency of 12.33%at−0.3 V versus reversible hydrogen electrode(ν***),with outstanding electrochemical and structural stability.

Compared to commercial lithium-ion batteries, all-solid-state batteries can greatly increase the energy density, safety, and cycle life of batteries. The development of solid-state electrolyte with high lithium-ion conductivity and wide electrochemical window is the key for all-solid-state batteries. In this work, we report on the achievement of high ionic conductivity in the PAN/LiClO_(4)/BaTiO_(3) composite solid electrolyte (CSE) prepared by solution casting method. Our experimental results show that the PAN-based composite polymer electrolyte with 5 wt% BaTiO_(3) possesses a high room-temperature lithium-ion conductivity (9.85 × 10^(−4) S⋅cm^(−1)), high lithium-ion transfer number (0.63), wide electrochemical window (4.9 V vs Li+/Li). The Li|Li symmetric battery assembled with 5 wt% BaTiO_(3) can be stably circulated for 800 h at 0.1 mA⋅cm^(−2), and the LiFePO_(4)|CSE|Li battery maintains a capacity retention of 86.2% after 50 cycles at a rate of 0.3 C. The influence of BaTiO_(3) ceramic powder on the properties of PAN-based polymer electrolytes is analyzed. Our results provide a new avenue for future research in the all-solid-state lithium battery technology.

眼内炎是眼科术后最为严重的并发症,结膜囊消毒是目前公认的能有效减少眼内炎发生的重要措施。目前已应用临床或在研究的结膜囊消毒剂主要有:汞剂、庆大霉素、聚维酮碘、酸性电解质水。备类消毒剂通过不同的途径发挥消毒杀菌作用。目前临床应用最为广泛的结膜囊消毒剂是聚维酮碘,汞剂及庆大霉素因其对环境的污染、易产生耐药菌、局部副反应重等原因现已鲜少使用于临床。酸性电解质水目前亦尚未使用于临床。随着眼科手术的普及及发展,眼科医师对患者术后眼部舒适度也越来越关注,未来结膜囊消毒剂的研究与应用将不断更新发展。
