Catalytically Enhanced Near Room‐Temperature Hydrogen Sensing Using Pd‐ZnO Colloidal Crystals

Advanced Functional Materials, EarlyView.
Pd‐decorated ZnO colloidal crystal monolayers demonstrate excellent performance across a wide hydrogen concentration range at 33°C, with high selectivity and reproducible device fabrication. The sensors show strong responses even at low‐ppm H2 concentrations and an ultra‐low detection limit of 82 ppb, indicating their suitability for diverse hydrogen ...

Tunable Complementary Doping Strategy Enables High‐Performance Homo‐Channel CMOS in Monolayer WSe2

Advanced Functional Materials, EarlyView.
Polarity‐selective modulation enables a homo‐channel WSe2 CMOS platform from a single 2D semiconductor. MoOx and AlN tune WSe2 toward p‐ and n‐type operation, respectively, yielding complementary FETs and inverters with balanced switching, high voltage gain, low static power, and promising scalability for 2D logic integration.

Mitigating Concentration Polarization in Dry‐Processed Ultra‐Thick Cathodes Using a Low‐Viscosity Electrolyte With Soft Li+ Solvation

Advanced Functional Materials, EarlyView.
A low‐viscosity, soft‐solvating methyl ethanoate (ME)‐based electrolyte facilitates electrolyte infiltration into dense dry‐processed ultra‐thick NCM622 cathodes while reducing Li+ desolvation barriers at Li‐metal anodes. Balanced cathode‐scale ion transport and anode‐side interfacial kinetics mitigate concentration polarization and interfacial ...

拉远基站与系统设备的互联互通

Guangtongxin yanjiu, 2006
随着3G牌照发放日期的逐步临近,人们对第3代移动通信（3G）的认识也更加清晰。2G与3G将融合发展,平滑过渡。2G业务增长的数据显示,2G还有很大的发展空间,2G与3G的过渡将是一个长期的过程。3G将首先在一些热点地区、业务量大的地方优先使用,在开始的时候没有必要大规模铺网,只需采用一些拉远基站就可以解决这些地区的3G覆盖问题。文章从网络应用的角度论述了拉远基站在未来3G组网中的重要作用,分析了目前部署3G拉远基站可能存在的问题,对互联互通、站址和网管等问题的解决方法提出了建议。
