Surface adsorption characteristics of nano-titania colloid particles and its influences on the dispersity of nano-titania powders(纳米二氧化钛粉体表面的吸附特征及其对粉体分散性的影响)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2004
以四氯化钛(TiCl4)为原料,采用3种不同的沉淀剂制备了纳米二氧化钛粉体.用TG-DTA和FT-IR对前驱体进行了分析.结果表明,不同沉淀剂导致粉体表面状态不同.以乙酸和尿素为沉淀剂的粉体表面不仅沉淀剂可以形成化学吸附,水分子也参与反应并在粉体表面形成-OH基团,而以EDTA为沉淀剂的粉体表面只吸附沉淀剂.煅烧后,用TEM对颗粒形貌进行了表征.实验发现,以EDTA为沉淀剂制备的粉体分散性优于其他沉淀剂制备的二氧化钛颗粒.这些差异主要是由于沉淀剂的性质及其在粉体表面的吸附状态不同.

Faecalibacterium prausnitzii‐derived microbial anti‐inflammatory molecule regulates intestinal integrity in diabetes mellitus mice via modulating tight junction protein expression 普拉梭菌活性产物‐微生物抗炎分子通过调控细胞紧密连接蛋白表达修复糖尿病小鼠肠道屏障

open access: yesJournal of Diabetes, Volume 12, Issue 3, Page 224-236, March 2020., 2020
Highlights Diabetic conditions induce compositional dysbiosis of the gut microbiota and impair gut barrier integrity. Diabetic conditions markedly downregulate the abundance of Faecalibacterium prausnitzii in the gut. Under diabetic conditions, microbial anti‐inflammatory molecules from Faecalibacterium prausnitzii restore the gut barrier and ZO‐1 ...

钙矾石法去除脱硫废水硫酸根沉淀物沉降特性研究

open access: yesGongye shui chuli, 2022
硫酸根难以稳定高效去除,造成浓缩、蒸发单元结垢是工业废水零排放系统面临的主要难题之一。以脱硫废水为研究对象,开展了钙矾石法深度去除硫酸根与沉淀物沉降条件优化研究,系统分析了初始n(Ca2+)/n(SO42-)(ICS)、n(Al3+)/n(SO42-)(IAS)和混合条件的影响机制,利用扫描电镜、X 射线衍射等手段对沉淀物进行了表征。结果表明,钙矾石沉淀法的硫酸根去除率可达99.5%;由于形成沉淀物的Zeta电位较高,静电斥力影响了沉淀物颗粒的聚集,造成沉降性能恶化 ...

Organ‐specific ozone and nitrogen legacies strengthen substrate control over litter decomposition

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Elevated tropospheric ozone (O3) and nitrogen (N) deposition are concurrent atmospheric changes that strongly influence terrestrial carbon cycling, yet their combined effects on below‐ground decomposition remain poorly understood.

High‐Value Targeted Conversion of Copper Slag as LiFePO4 Material for Lithium‐Ion Batteries

open access: yesRare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT The massive stockpiling of copper slag (CS) presents severe environmental and resource‐waste challenges. Existing strategies for CS valorization typically yield low‐value‐added products. Herein, we propose an innovative hierarchical regulation approach to transform CS into high‐performance LiFePO4 (LFP) cathode materials.

响应面法优化混凝处理夏季高浊度黄河水

open access: yesGongye shui chuli, 2020
采用聚合氯化铝铁混凝处理兰州夏季超高浊度黄河水,通过单因素实验考察了混凝剂投加量、沉淀比表面负荷及沉淀时间对处理效果的影响,并以响应面法对这些因素进行了优化。结果表明,各因素对浊度去除率、CODMn去除率的影响次序:混凝剂投加量>沉淀比表面负荷>沉淀时间;最佳混凝条件:混凝剂投加量640 mg/L,沉淀比表面负荷0.08 m3/m2,沉淀时间32 min。在最佳条件下,浊度和CODMn的平均去除率分别为98.62%、98.14%,与模型预测值相对偏差分别为0.5%、0.86%。

Effect of Heterogenous Gradient Structure Induced by High Cu Content on Nanocrystallization Process and Magnetic Properties of Fe‐Based Nanocrystalline Alloys

open access: yesRare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT The pre‐existing α‐Fe crystals have important effects on the precipitation and growth of nanocrystals and finally determine the comprehensive soft magnetic properties (SMPs) of the nanocrystalline alloys (NAs). In this work, a high content of Cu elements has been added to Nanomet‐type alloys to enhance the gradient heterogeneity in order to ...
