阳极氧化技术作为最简单的高级氧化技术,可有效去除水中残留的除草剂等持久性有机污染物。利用硼掺杂金刚石(BDD)电极作为阳极构建了阳极氧化体系,研究了电解质种类、浓度和电流密度等参数对BDD阳极降解三嗪类除草剂阿特拉津效能的影响规律,并利用UPLC-MS/MS对阿特拉津的降解产物进行了定性分析。结果表明,在NaCl投加量为0.05 mol/L和电流密度为12 mA/cm2时,处理90 min后,BDD阳极基本可实现对阿特拉津的完全去除;处理300 min后,阿特拉津的矿化率可达(56±2.4 ...

ABSTRACT Dielectric polymers commonly suffer from severe performance degradation above 150°C, hindering advanced power systems. Herein, we demonstrate a polyetherimide (PEI) nanocomposite that overcomes this by mimicking the gradient architecture of nacre and bamboo, incorporating a continuous vertical gradient of fluorinated boron nitride nanosheets ...

ABSTRACT Aqueous zinc‐ion batteries (AZIBs) have attracted increasing attention in energy storage owing to their high energy density, low redox potential, and cost‐effectiveness. Nevertheless, uncontrolled dendrite accumulation, gas generation, and severe side‐reaction problems hinder the cycling lifespan, which prevents their commercial applications ...

提出了一种将极化效应引入GaN基异质结器件模拟中的方法.在传统器件模拟软件中,通过在异质结界面插入δ掺杂层,利用其离化的施主或受主充当极化产生的固定电荷从而引入极化效应.模拟了Ga面生长和N面生长的AlGaN/GaN单异质结,结果显示只有前者在异质结界面有载流子限制效应,而后者没有;Ga面生长的AlGaN/GaN异质结界面处自由电子面密度随Al组分以及AlGaN的厚度增加而增加.以上模拟结果与其他报道中的实验以及计算结果一致 ...
