渗漏水是危害隧道安全的常见病害之一,针对衬砌表面有装饰层遮挡的隧道,提出了在装饰层外检测渗漏水的探地雷达方法。首先,根据对电磁波传播特性进行分析,从理论上论证了该方法的可行性,得出衬砌有无渗透水时其表面电磁波反射系数不同。当衬砌表面的反射系数小于-0.433时,可认为该处有渗漏水发生。然后,给出了从雷达回波中判定渗漏水的方法,通过试验探测获得衬砌无渗漏条件下的探地雷达回波作为参考信号,将检测得到的雷达回波与已知无渗漏水条件下的雷达回波做差,有渗漏水时在衬砌表面会出现负向反射,且渗漏量越大反射越强烈。最后,通过数值模拟试验对所提出的方法进行验证,采用电磁波时域有限差分法模拟探地雷达在隧道装饰层外对衬砌进行探测,分别模拟衬砌无渗漏有渗漏情况下的探地雷达回波。将模拟的回波减去衬砌无渗漏条件下的回波后,从振幅分析可以得出:衬砌无渗漏发生时,振幅保持为零,在有渗漏水位置负向振幅显著增大,且渗漏水越严重的位置反射越强;该方法能有效检测出衬砌出现渗漏的部位,且通过对回波的振幅分析可定性评价渗漏量的大小。所提方法有效易行,在实际工程中具有一定的应用推广价值。

lithium-sulfur （li-S） batteries have gained great attention due to the high theoretical energy density and low cost,yet their further commercialization has been obstructed by the notorious shuttle effect and sluggish redox ***,we supply a strategy to optimize the electron structure of Ni2P by concurrently introducing B-doped atoms and P vacancies in Ni2P （Vp-B-Ni2P）,thereby enhancing the bidirectional sulfur *** study indicates that the simultaneous introduction of B-doped atoms and P vacancies in Ni2P causes the redistribution of electron around Ni atoms,bringing about the upward shift of d-band center of Ni atoms and effective d-p orbital hybridization between Ni atoms and sulfur species,thus strengthening the chemical anchoring for lithium polysulfides （liPSs） as well as expediting the bidirectional conversion kinetics of sulfur ***,theoretical calculations reveal that the incorporation of B-doped atoms and P vacancies in Ni2P selectively promotes li2S dissolution and nucleation ***,the li-S batteries with Vp-B-Ni2P-separators present outstanding rate ability of 777 m A h g-1at 5 C and high areal capacity of 8.03 mA h cm-2under E/S of 5μL mg-1and sulfur loading of 7.20 mg *** work elucidates that introducing heteroatom and vacancy in metal phosphide collaboratively regulates the electron structure to accelerate bidirectional sulfur conversion.

Schwann cell transplantation is considered one of the most promising cell-based therapy to repair injured spinal cord due to its unique growth-promoting and myelin-forming properties.A the Food and Drug Administration-approved Phase I clinical trial has been conducted to evaluate the safety of transplanted human autologous Schwann cells to treat patients with spinal cord injury.A major challenge for Schwann cell transplantation is that grafted Schwann cells are confined within the lesion cavity,and they do not migrate into the host environment due to the inhibitory barrier formed by injury-induced glial scar,thus limiting axonal reentry into the host spinal *** we introduce a combinatorial strategy by suppressing the inhibitory extracellular environment with injection of lentivirus-mediated transfection of chondroitinase ABC gene at the rostral and caudal borders of the lesion site and simultaneously leveraging the repair capacity of transplanted Schwann cells in adult rats following a mid-thoracic contusive spinal cord *** report that when the glial scar was degraded by chondroitinase ABC at the rostral and caudal lesion borders,Schwann cells migrated for considerable distances in both rostral and caudal *** Schwann cell migration led to enhanced axonal regrowth,including the serotonergic and dopaminergic axons originating from supraspinal regions,and promoted recovery of locomotor and urinary bladder ***,the Schwann cell survival and axonal regrowth persisted up to 6 months after the injury,even when treatment was delayed for 3 months to mimic chronic spinal cord *** findings collectively show promising evidence for a combinatorial strategy with chondroitinase ABC and Schwann cells in promoting remodeling and recovery of function following spinal cord injury.
