Heterostructure photocatalysts with a built-in electric field have become one of the most promising strategies to enhance photogenerated electron-hole pair separation. However, close contact between the two active components of heterogeneous photocatalysts remains a problem. Herein, the in-situ fabrication of an SnO2/SnS2 heterostructure photocatalyst was performed;the structure showed enhanced photocatalytic performance resulting from the tight-contact heterostructures. The results of photoelectrochemical measurements further verified that a tight-contact heterostructure improved the separation of photogenerated electron-hole pairs. The results of EIS Bode plots also demonstrated that such in-situ fabricated SnO2/SnS2 samples exhibited the longest carrier lifetime(41.6 μs) owing to the intimate interface of SnO2/SnS2 heterostructures.

为研究短历时设计暴雨对地下空间内涝的影响规律,该文采用GAST模型和SWMM模型耦合的一维二维水动力模型,以陕西西咸新区沣西新城天福和园小区为研究对象,模拟小区地下车库在极端降雨条件下的洪水演进过程,探究临时挡水措施对小区地下车库进水量的影响。研究结果表明:与两场实测降雨数据对比,耦合模型的纳什效率系数为0.59和0.69,模拟结果较好,该模型可精确可靠地模拟地表地下洪水过程;随着设计降雨重现期的增加,地下空间进水量逐渐增大;在短历时设计暴雨情景下,当累计降雨量大于52 mm时,地下车库会有淹没风险;采用0.3 m临时挡水措施,可使小区地下车库在短历时设计暴雨10~50 a重现期条件下不发生淹没,使设计暴雨100 a重现期条件下的车库进水量削减39.23%;采用0.5 m挡水措施,可使小区地下车库不发生淹没,完全消除内涝风险。综上所述,一维二维耦合水动力模型可精细模拟地表地下洪水过程,为地下空间科学防涝减灾提供参考依据。

The in-plane thermal conductivity of the iron-based superconductor Ca10（Pt4δAs8）（（Fe1-xPtx）2As2）5 single crystal （＂10-4-8＂, Tc = 22 K） was measured down to 80 inK. In a zero field, the residual linear term ro/T is negligible, suggesting the nodeless superconducting gaps in this multiband compound. In the magnetic fields, r0/T increases rapidly, which mimics the multiband superconductor NbSe2 and LuNi2B2C with highly anisotropic gap. Such a field dependence of K0/T is an evidence for the multiple superconducting gaps with quite different magnitudes or highly anisotropic gap. Compared with the London penetration depth results of the Ca10（Pt3As8）（（Fe1-xPtx）zAs2）5 （＂10-3-8＂） compound, the 10-4-8 and 10-3-8 compounds may have a similar superconducting gap structure.

短历时暴雨是形成城市内涝的主要原因,其雨型对内涝致灾影响显著。以陕西省西咸新区沣西新城为研究区域,基于模式雨型设计了具有不同集中度的典型暴雨过程,并考虑了降雨空间分布的不均匀性,应用城市雨洪模型(GAST-SWMM耦合模型)对7种模式雨型在不同重现期下的致涝特征进行模拟分析。结果表明:(1)单峰雨型比双峰雨型具有更强的致涝性,雨峰为中后峰的单峰雨型致涝性更强,雨峰为中峰的单峰雨型在小于50 a重现期下淹没量最大,而在大于50 a重现期下雨峰为后峰的单峰雨型淹没量最大,100 a重现期下其淹没量较雨型Ⅳ增大6.58%;(2)双峰雨型中雨型Ⅴ的致涝性最强,在100 a重现期时,其淹没量较雨型靠前的单峰雨型增加1912.42 m^(3);在大于20 a重现期时,雨型Ⅴ在中风险区的积水面积较雨峰靠前的单峰雨型增大1.81%~2.29%;(3)各雨型在高风险区的积水面积峰现时间随重现期的变化而不同,雨型Ⅵ的峰现时间始终在降雨结束时出现,雨型Ⅱ、Ⅳ、Ⅴ、Ⅶ的峰现时间随着重现期增大而提前;雨型Ⅰ、Ⅲ的峰现时间在小于20 a重现期时随着重现期增大,分别从105 min延后至120 min、110 min,在大于20 a重现期时随着重现期增大,分别从120 min、110 min提前到100 min。城市内涝特征对不同模式雨型条件下的响应规律的研究,可为相关部门抗涝救灾提供参考。

Unsaturated magnetoresistance （MR） has been reported in type-II Weyl semimetal WTe2, manifested as a perfect compensation of opposite carriers. We report linear MR （LMR） in WTe2 crystals, the onset of which was identified by constructing the MR mobility spectra for weak fields. The LMR further increased and became dominant for fields stronger than 20 T, while the parabolic MR gradually decayed. The LMR was also observed in high-pressure conditions.
