Development of a high-performance bifunctional catalyst is essential for the actual implementation of zinc-air batteries in practical ***,a bifunctional cathode of Co_(3)S_(4)/FeS heterogeneous nanoparticles embedded in Co/Fe single-atom-loaded nitrogen-doped carbon nanosheets is ***-iron sulfides and single atomic sites with Co-N_(4)/Fe-N_(4)configurations are confirmed to coexist on the carbon matrix by EXAFS spectroscopy.3D self-supported super-hydrophobic multiphase composite cathode provides abundant active sites and facilitates gas–liquid-solid three-phase interface reactions,resulting in excellent electrocatalytic activity and batteries performance,i.e.,an OER overpotential(η_(10))of 260 mV,a half-wave potential(E_(1/2))of 0.872 V for ORR,aΔE of 0.618 V,and a discharge power density of 170 mW cm^(−2),a specific capacity of 816.3 mAh g^(−1).DFT analysis shows multiphase coupling of sulfide heterojunction through single-atomic metal doped carbon nanosheets reduces offset on center of electronic density of states before and after oxygen adsorption,and spin density of adsorbed oxygen with same spin orientation,leading to weakened charge/spin interactions between adsorbed oxygen and substrate,and a lowered oxygen adsorption energy to accelerate OER/ORR.

Based on the commercial computational software, a three-dimensional finite ele- ment model to simulate the thermo-mechanical behaviors in a nuclear fuel rod is established; By taking into consideration irradiation-swelling of the pellet and the irradiation damage effects in the cladding together with the coupling effects between the temperature field and the mechanical field, the user subroutines to define the special material performance and boundary conditions have been developed independently and validated. Three-dimensional numerical simulation of the thermo-mechanical coupling behaviors in a nuclear fuel rod is carried out, and the evolution rules of the important thermal and mechanical variables are obtained and analyzed. The research re- sults indicate that：（i） the fuel pellets will be in contact with the cladding at high burnup, which will induce a strong mechanical interaction between them; （2） the irradiation creep effect plays an important role in the mechanical behavior evolution in the nuclear fuel rod.

环境中Pb^(2+)的浓度是环保管控领域重要的监测指标之一,过量Pb^(2+)的存在对人类健康及环境生态稳定构成严重威胁。通过简易原位电致聚合的方法,成功地将聚多巴胺涂层修饰于电极表面,并将其应用于水中痕量Pb^(2+)的电化学检测分析。结果表明,Pb^(2+)能与聚多巴胺表面丰富的功能基团(-OH、-NH2等)发生螯合作用,并被富集于电极表面;通过阳极溶出伏安法,Pb^(2+)会从电极表面再次溶出,从而形成灵敏且具有特异性的电化学信号。通过考察电解质、pH及富集时间等实验参数对Pb^(2+)溶出电流信号强度的影响,进一步优化了该方法对水中Pb^(2+)的检测性能,其检测范围为50~800 nmol/L,理论检测限能够达到32 nmol/L。将其拓展至实际水样中Pb^(2+)的测定,平均回收率可达到95%左右。该简易电极修饰策略能够为便携式环境痕量重金属离子灵敏性检测分析传感器设计提供新的思路。
