The lack of effective charge transfer driving force and channel limits the electron directional migration in nanoclusters(NC)-based heterostructures,resulting in poor photocatalytic ***,a Z-scheme NC-based heterojunction(Pt1Ag28-BTT/CoP,BTT=1,3,5-benzenetrithiol)with strong internal electric field is constructed via interfacial Co-S bond,which exhibits an absolutely superiority in photocatalytic performance with 24.89 mmol·h^(−1)·g−1 H_(2)production rate,25.77%apparent quantum yield at 420 nm,and~100%activity retention in stability,compared with Pt1Ag28-BDT/CoP(BDT=1,3-benzenedithiol),Ag29-BDT/CoP,and *** enhanced catalytic performance is contributed by the dual modulation strategy of inner core and outer shell of NC,wherein,the center Pt single atom doping regulates the band structure of NC to match well with CoP,builds internal electric field,and then drives photogenerated electrons steering;the accurate surface S modification promotes the formation of Co-S atomic-precise interface channel for further high-efficient Z-scheme charge directional *** work opens a new avenue for designing NC-based heterojunction with matchable band structure and valid interfacial charge transfer.

为筛选出适合杉木优良无性系洋-061容器苗生长的轻型基质配方。采用单纯形-重心混料试验设计,以泥炭土、珍珠岩、杉木皮和稻谷壳为材料,并以黄心土为对照(CK),研究不同轻型基质配比对杉木生长、根系形态和养分积累的影响。结果表明,1)不同轻基质配方(T1-T14)和对照(CK)处理的苗高、地径和生物量均表现出相同的生长规律,即随时间增加而逐渐增大。2)当苗木培育360 d时,不同轻型基质处理苗高、地径和苗木质量指数均高于CK,其中,苗高在T6处理最大,较CK增加了54.89%,地径和苗木质量指数在T6和T1处理时达到最大,分别较CK提高33.04%和48.65%,T14处理下生物量最大;3)不同轻型基质处理有效促进了杉木幼苗根系的发育,而且其总根长、根表面积、根直径及根体积分别在T2、T14、T9和T14处理时达到最大;4)杉木植株养分含量对不同轻型基质响应存在差异,其中轻型基质T5、T3和T12处理显著促进植株氮的积累,轻型基质T8、T3和T13处理苗木全磷含量显著高于其他处理,而T8、T9和T2植株全钾含量显著高于其他处理;5)利用隶属函数对幼苗生长指标进行综合分析,综合评价排名前3的依次是T14(20%泥炭土+27%珍珠岩+27%杉木皮+26%稻谷壳)、T5处理(60%泥炭土+40%珍珠岩)和T1处理(100%泥炭土)。考虑到泥炭土成本较高,因此,T5和T14处理为本研究中适合于杉木洋-061容器苗生长的轻型基质配方。

目的评估颈动脉周围脂肪炎症与斑块内出血(IPH)之间的关联,利用计算机断层扫描血管造影(CTA)技术,测量血管周围脂肪密度(PFD),以此反应脂肪组织的炎症情况。方法收集我院连续行颈动脉CTA、颈动脉HR-MRI检查的患者的临床基线资料及影像资料。测量患者颈动脉CTA斑块侧、对侧PFD。选取每位患者管腔狭窄最严重的颈动脉段进行分析,计算斑块侧PDF、非斑块侧PDF及二者PFD差值(ΔPFD)。根据颈动脉高分辨MRI结果将患者分为斑块内出血组(IPH组)、非斑块内出血组(非IPH组)。比较2组患者临床基线资料、PFD的差异。采用SPSS 26.0进行统计分析。先通过独立样本t检验评估IPH组和非IPH组患者斑块侧与对侧PFD之间的差异,再通过配对样本t检验评估两组患者斑块侧与对侧PFD之间差异,最后将斑块侧颈动脉PFD纳入二元logistic回归分析并绘制ROC曲线。P<0.05为差异具有统计学意义。结果本研究共纳入64例患者,平均年龄(67.9±8.9)岁。IPH组患者颈动脉斑块侧PFD高于非IPH组[(-44.21±14.75)HU vs(-64.87±13.25)HU],差异具有统计学意义(P<0.001),IPH组患者颈动脉ΔPFD高于非IPH组[(53.91±24.82)HU vs(35.88±14.52)HU],差异具有统计学意义(P=0.001),IPH组患者最大斑块厚度高于非IPH组[(4.76±1.97)mm vs(3.88±1.49)mm],差异具有统计学意义(P=0.046)。两组患者配对t检验结果显示,IPH组患者颈动脉斑块侧PFD均值[(-44.21±14.75)vs(-97.20±20.43),P<0.001]高于对侧,非IPH组患者颈动脉斑块侧PFD均值[(-64.87±13.25)vs.(-99.14±11.21),P<0.001]同样高于对侧。二元logistic回归分析显示,调整混杂因素后颈动脉斑块侧PFD(OR=1.194,95%CI:1.059~1.347)差异具有统计学意义(P<0.05)。ROC曲线分析显示,颈动脉PFD均值[ROC曲线下面积(AUC)为0.853,95%CI:0.761~0.946,P<0.001]对IPH的发生具有较高预测价值。结论颈动脉PFD与颈动脉易损斑块特征IPH存在相关,PFD为IPH的早期预测和风险分层提供了依据。

The origin and cycling of volatiles, including water, carbon dioxide, and nitrogen, are fundamental to the very existence of habitable planets. These volatile compounds, often taken for granted,are the lifeblood of planetary systems, influencing almost everything from atmospheric composition and climate regulation to deep Earth processes and the emergence of life.
