Enhanced Treatment of Printing and Dyeing Wastewater Using H2O2-Biochemical Method
, 2017 传统生化法对印染废水的处理有一定的局限性。本文研究了双氧水协同水解酸化-接触氧化系统,对印染废水进行强化处理。采用污泥挂膜、生化系统启动、双氧水协同启动的方法,将双氧水投加到水解酸化时的条件严格控制为:投加浓度3 mL·L-1、投加量100.0 mL、流速0.67 mL·min-1、投加频率1次·d-1,可使整个系统成功启动与稳定运行。实验结果表明,双氧水协同水解酸化-接触氧化可对印染废水中的特征污染物进行有效强化处理。其中,COD平均去除率为89.8 ...

Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Lignin hydrogenolysis is a promising route to separable aromatic monomers, yet practical upgrading is still hindered by macromolecular mass‐transfer limitations and the aggregation/deactivation of metal sites. Herein, we propose a “dual‐confinement” strategy to construct ultrafine Ru nanoclusters supported on lignin‐based N‐doped hierarchical ...

Time‐Efficient Columnar‐to‐Equiaxed Transition via High Magnetic Field Processing
Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT The need to simplify processing routes and improve processing efficiency motivates the development of time‐efficient methods for inducing the columnar‐to‐equiaxed transition (CET) during solidification while tailoring material performance. Conventional multistep CET approaches are time‐consuming and often struggle to simultaneously regulate ...

Unveiling Entropy‐Driven Hard‐Tough Synergy Mechanisms in High‐Entropy Carbonitride Ceramics
Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT High‐entropy ceramics manifested promise for extreme environments, yet their phase stability and mechanical synergy mechanisms remain elusive. Herein, entropy‐difference carbonitrides, including (TaTiV)CN, (TaTiVNb)CN, and (TaTiVNbHf)CN, were designed and consolidated via spark plasma sintering.

Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Platinum‐based electrocatalysts are fundamentally constrained by strong oxygen binding, which restricts the oxygen reduction reaction (ORR) kinetics, and by severe CO poisoning, which hinders the methanol oxidation reaction (MOR). To address these limitations, we synthesized PdPtRuIrRhNi high‐entropy alloy (HEA) mesoporous nanotubes that ...

Wildlife Letters, Volume 4, Issue 3, Page 149-159, September 2026.Migratory shorebirds traveling the East Asian–Australasian Flyway face systemic policy fragmentation and habitat disconnection between China (coordination challenges and renewable energy conflicts) and Australia (federal governance fragmentation). This study proposes a transboundary conservation framework to fill this gap.
