A High Capacity‐Long Cycling Concurrent Strategy of Ti3C2/MgH2 for Lithium Storage
Rare Metals, EarlyView.ABSTRACT The excellent electrical conductivity and superior cycling stability render Ti3C2 MXene a promising Li ion battery anode. Nevertheless, the practical implementation of Ti3C2 MXene in commercial applications faces significant challenges, predominantly due to the low specific capacity.

Multipath traffic splitting algorithm based on adaptive granularity [PDF]
, 2015 Aiming at the dilemma between load balancing and packet reordering in multipath routing,an adaptive dynamic multipath traffic splitting(ADTS) algorithm was proposed.The algorithm classified Internet flows into two categories:the aggressive and the normal

Rare Metals, EarlyView.ABSTRACT Aqueous zinc‐ion batteries (AZIBs) hold great promise for safe and sustainable energy storage, but their commercialization is impeded by severe Zn dendrite growth and interfacial instability. To address these challenges, we propose a defect engineering strategy employing ultrafine ZnAl2O4 (ZAO) nanoparticles (∼5 nm) with oxygen vacancy defects

Shuitu Baochi Xuebao, 2003 降雨是影响低丘红壤坡地土壤侵蚀和养分随径流迁移的一个关键因子.利用三角量 水堰自动测量径流量和自动雨量计观测数据,分析了鹰潭小流域的季节性降雨径流特征.小流域降雨主要发生在4～6月,总量达512.4 mm,占观测时段总雨量的70.1%,而旱季7～9月仅为218.9 mm.上游、下游围堰累积径流量随旱季、雨季的变化表明:小流域降雨-径流- 土壤水界面水分转化可分为土壤水补给阶段(4月14日～6月14日)、土壤水饱和阶段(6月15 日～7月28日)和土壤水消耗阶段(7月28日以后 ...

Contribution of Different Processes in Wetland Soil N_2O Production in Different Restoration Phases of the Yellow River Estuary, China [PDF]
, 2014 采用时空替代法,选择黄河口生态恢复前后未恢复区(R_0)、2007年恢复区(R_(2007))和2002年恢复区(R_(2002))的芦苇湿地为研究对象,分析了生态恢复工程对湿地土壤N_2O产生不同过程与贡献的影响. 结果表明,尽管不同恢复阶段湿地土壤N_2O总产生量差异明显,但总体均表现为N_2O释放. 恢复区湿地土壤的N_2O产生量大于未恢复区.

Submarine groundwater discharge in a subtropical bay and island traced by radium isotopes - Sansha bay and Dongshan island, Fujian [PDF]
, 2016 镭同位素来自母体钍的衰变，钍是强颗粒活性的元素，而其子体镭同位素却有一定的水溶性。223Ra、224Ra、226Ra、228Ra的半衰期分别为11.4天、3.6天、1600年和5.75年，这四种同位素的半衰期差异为近岸海域的水团混合和物质交换提供了重要的方法（Moore，1998）。其中，短半衰期的两种同位素能有效地示踪几天至几十天时间尺度的海洋学过程，而在这时间尺度内，长半衰期镭同位素的自身衰变可以忽略（Moore，1998;Moore，2000）。海底地下水排泄（SGD ...

Rare Metals, EarlyView.ABSTRACT Low conductivity, slow ion‐diffusion, and limited reactive sites are common problems in electrocatalysts and electrode materials. In this study, a complex NiTe–CoTe heterojunction with abundant Te vacancies embedded in N, P, and F co‐doped hollow carbon nanorods (NiTe1−x–CoTe1−x/NPFC) was fabricated via a simple ionic liquid‐assisted ...
