Gongye shui chuli, 2002 研究了碳钢在臭氧和Cr(Ⅵ)溶液中的腐蚀速率。试验结果表明，臭氧和Cr(Ⅵ)具有良好的协同缓蚀作用。这种协同缓蚀作用与臭氧质量浓度和Cr(Ⅵ)质量浓度有关，Cr(Ⅵ)质量浓度升高，协同缓蚀效果提高;协同缓蚀作用的最佳臭氧质量浓度范围为0。05～0。1mgL。在最佳臭氧质量浓度范围内，当Cr(Ⅵ)为2。5～5。0mgL时，碳钢可以取得较好的缓蚀效果。采用铬酸盐对碳钢进行预膜，可以有效提高臭氧与Cr(Ⅵ)的协同缓蚀效果。

Synchronous treatment of Cr(Ⅵ) and p-NCB by Nanoscale Ni/Fe Bimetal(纳米级镍铁同步处理Cr(Ⅵ)和p-NCB的研究)
Zhejiang Daxue xuebao. Lixue ban, 2008 采用纳米级镍/铁双金属体系同步处理含Cr（Ⅵ）和p-NCB的废水，考察了反应温度、初始pH值和Cr (Ⅵ)、p-NCB浓度变化以及Ni(Ⅱ)存在对处理效率的影响.结果表明：纳米级镍/铁双金属应用于Cr(Ⅵ)和p-NCB同步处理，可以取得良好的去除效率.反应产物为Cr(Ⅲ)和苯胺.Ni(Ⅱ)可以促进p-NCB的还原降解，而水中的Cr (Ⅵ)会与p-NCB起竞争作用，从而抑制p-NCB的还原降解.

Pathways and pitfalls: a qualitative study of student experiences in biomedical science education
FEBS Open Bio, EarlyView.Biomedical science students from underrepresented backgrounds face barriers including financial strain, disrupted laboratory access and cultural exclusion. Peer networks provide vital support when institutional systems are difficult to navigate. To create inclusive learning environments and achieve academic success, educators should blend active, hands‐

, 2005 研究了酸碱2步改性对活性炭吸附水相中Cr（Ⅵ）的影响.将活性炭（AC0）在HNO3溶液中氧化（AC1）,然后在NaOH和NaCl的混合液中处理（AC2）.分别采用平衡和连续吸附试验,测试Cr（Ⅵ）的吸附特征.以Boemh滴定法定量检测活性炭表面酸性官能团数量,结合元素分析结果定量表征活性炭的表面含氧官能团变化;以低温液氮（N2/77K）吸附法分析活性炭的比表面积和孔径结构.结果表明：活性炭经2步改性后,其Cr（Ⅵ）的吸附容量和吸附速度均显著改变.吸附容量和吸附速度大小依次为AC2＞AC1＞AC0 ...

Gongye shui chuli, 2008 将三价铁固载在胶原纤维上制备吸附材料，并研究了该吸附材料对电镀废水中Cr(Ⅵ)的吸附特性。结果表明:胶原纤维固化铁(FeICF)对Cr(Ⅵ)有较强的吸附能力，在pH为3.0～8.0的范围内，FeICF对Cr(Ⅵ)的吸附量达到21.0mg/g以上;随着吸附剂用量的增加，Cr(Ⅵ)的去除率提高，当在Cr(Ⅵ)质量浓度为25mg/L的50mL混合溶液中投加吸附剂0.100g时，FeICF对Cr(Ⅵ)的去除率为71.5%，而当吸附剂用量为0.500g时，去除率达到90.3%;溶液中的其他共存金属离子Ni(Ⅱ ...

Mutant NPM1 in Acute Myeloid Leukemia Initiation and Maintenance
Aging and Cancer, EarlyView.NPM1 mutations drive acute myeloid leukemia by acting as neomorphic transcriptional regulators that cooperate with Menin–MLL and XPO1 to sustain HOX/MEIS1 expression and block differentiation. Targeting these mutant‐specific transcriptional dependencies provides a rational therapeutic strategy for NPM1‐mutated AML.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background and Objectives Multiple sclerosis (MS) exhibits racially disparate rates of disease progression. Black people with MS (B‐PwMS) experience a more severe disease course than non‐Hispanic White people with MS (NHW‐PwMS). Here we investigated structural and functional connectivity as well as structure–function decoupling in the ...

Vestibular Patient Journey: Insights From Vestibular Disorders Association (VeDA) Registry
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Vestibular symptoms impose a high burden of disability. Understanding real‐world diagnostic and treatment pathways can identify care gaps and guide interventions. We aimed to characterize symptom profiles, diagnostic trends, provider involvement, and treatment patterns in vestibular disorders.
