Sodium-doped carbon nitride nanotubes （Nax-CNNTs） were prepared by a green and simple two-step meth.d and applied in ph.tocatalytic water splitting for th. first time. Transmission electron microscopy （TEM） element mapping and X-ray ph.toelectron spectroscopy （XPS） measurements confirm th.t sodium was successfully introduced in th. carbon nitride nanotubes （CNNTs）, and th. intrinsic structure of graph.tic carbon nitride （g-C3N4） was also maintained in th. products. Moreover, th. porous structure of th. CNNTs leads to relatively large specific surface areas. Ph.tocatalytic tests indicate th.t th. porous tubular structure and Na＋ doping can synergistically enh.nce th. h.drogen evolution rate under visible ligh. （λ 〉 420 nm） irradiation in th. presence of sacrificial agents, leading to a h.drogen evolution rate as h.gh.as 143 μmol·h.1 （20 mg catalyst）. Moreover, oth.r alkali metal-doped CNNTs, such.as Lix-CNNTs and Kx-CNNTs, were tested; both.materials were found to enh.nce th. h.drogen evolution rate, but to a lower extent compared with.th. Nax-CNNTs. Th.s h.gh.igh.s th. general applicability of th. present meth.d to prepare alkali metal-doped CNNTs; a preliminary mech.nism for th. ph.tocatalytic h.drogen evolution reaction in th. Nax-CNNTs is also proposed.

Background:Th.s study was performed to investigate th. situations in wh.ch.computed tomograph. (CT) combined with.arterial portograph. and h.patic arteriograph. surpassed dynamic CT in th. detection of h.patocellular carcinoma. Meth.ds:Computed tomograph. combined with.arterial portograph. and h.patic arteriograph. was performed on 137 patients with.ch.onic h.patitis (92 men and 45 women; mean age, 66.5 years) with.h.patocellular carcinoma (h.C) as revealed or suspected by dynamic CT. We analyzed th. clinical factors leading to th. discovery of additional h.C lesions on CT combined with.arterial portograph. and h.patic arteriograph. th.t were undetected by dynamic CT. Results:Computed tomograph. combined with.arterial portograph. and h.patic arteriograph. detected additional h.C lesions th.t h.d not been revealed by dynamic CT in 33 of 137 patients. Univariate analysis revealed th.t in th. event of h.C recurrence (vs. primary), multiple h.C lesions detected by dynamic CT (vs. single) and decreased liver function (Ch.ld’s classification B/C vs. A) significantly favored th. additional detection of h.C lesions. Multivariate logistic regression indicated th.t recurrence was th. strongest predicting factor for finding additional lesions on computed tomograph. combined with.arterial portograph. and h.patic arteriograph.. Conclusions:Computed tomograph. combined with.arterial portograph. and h.patic arteriograph. is capable of finding additional h.C lesions undetectable by dynamic CT, especially in advanced cases such.as h.C recurrence, wh.ch.may affect th. ch.ice of treatment.

应用旋转环盘电极（RRDE）等电化学方法研究了在不同ph.件下,在银/溴化银电极上,亚硫酸盐(SO32-)对菲尼酮-对苯二酚超加合体系（P-h.Q体系）显影反应速率的影响。结果表明,显影液中的亚硫酸盐不仅起保护显影剂的作用,而且影响显影反应速率。在较低ph.亚硫酸盐起抑制显影的作用,而在较高的ph.,会促进显影反应。这种现象可以认为主要是由于亚硫酸盐存在时,不同ph.件下,对苯二酚的氧化还原性质不同而引起的。
