Gongye shui chuli, 2016 研究不同浓度的Ca2+、Mg2+、Fe3+对厌氧氨氧化颗粒污泥形成的影响。以血清瓶进行批次试验,分别投加0.300、0.045、0.060、0.075、0.090 mmol/L的金属离子并进行空白试验,考察颗粒污泥的形态、可颗粒化程度(SGR)、生物量、比厌氧氨氧化活性。结果表明:添加适量金属离子可以促进厌氧氨氧化污泥颗粒化。Ca2+、Mg2+、Fe3+的最佳投加浓度分别为0.030、0.060、0.060 mmol/L,最佳投加浓度情况下,以Mg2+的效果最优。

Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT In MAX‐phase‐derived metal–matrix composites, the M‐site element simultaneously governs carbide chemistry and matrix precipitate stability, yet it has traditionally been selected empirically rather than from a predictive criterion linking M‐site choice to carbide chemistry, matrix alloying, and L12 stability; moreover, the reaction pathway ...

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 8, August 2026.ABSTRACT The regeneration of osteoporotic bone defects is severely hampered by compromised endogenous healing capacity, demanding advanced strategies that actively orchestrate pro‐osteogenic microenvironments. Here, we report an integrated, self‐powered osteo‐regenerative system that uniquely leverages a dual ultrasound‐responsive piezoelectric ...

Gongye shui chuli采用颗粒粒径选择压与沉降速率选择压相结合的策略，在120 d内成功培养出白色除磷颗粒污泥，颗粒成熟后在反应器内因粒径分化出现分层，按粒径筛分为R1（<2 mm）、R2（2~4 mm）、R3（4~7 mm）、R4（>7 mm）共4组，考察了白色颗粒污泥的除污效能和理化性质。除污效能实验结果表明，在4组粒径范围内，白色颗粒污泥对COD去除效果均较好；4~7 mm的颗粒污泥对TP的去除率最优，达到99.94%；TN的去除率随着粒径的增大而增大，>7 mm的颗粒污泥对TN的去除率最优，达到82.

Gongye shui chuli, 1987 化学凝聚法是工业生产污水广泛采用的一种处理方法。化学凝聚法是在污水中加入一定的混凝剂,使水中的胶体稳定性受到破坏,细小颗粒互相吸附凝聚成较大颗粒,经过泥水分离,从而去除水中污染物。化学凝聚法主要是利用:(1)加入的混凝剂的产物压缩了水中胶体颗粒的双电子层,或者吸附作用降低胶核电荷,使本来相斥的胶体颗粒变成可以互相吸引的颗粒;(2)加入的混凝剂在水中产生了新的胶体颗粒 ...

Gongye shui chuli, 2018 自行研发的膨润土-钢渣复合颗粒是廉价高效矿物材料。通过探究其对Mn2+的去除效果及pH变化规律，对比分析了复合颗粒、脱碱颗粒与单独加碱对Mn2+的去除效果、现象及复合颗粒表面微观结构的SEM表征、XRD矿物相特征，探究其处理含Mn2+酸性矿山废水的协同机理。结果表明，复合颗粒处理含Mn2+废水不仅具有吸附、化学沉淀作用，且表面吸附Mn2+并形成表面化学沉淀后还会继续吸附发生聚沉作用，Mn2+在复合颗粒表面的赋存状态主要以Mn-Si-O相结合的矿物相及CaMn4Si5O14（OH）2聚合沉淀存在。

Insights Into the Temperature‐Dependent Oxidation Mechanism of Metallic Cerium in H2O‐N2 Atmospheres
Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Metallic cerium (Ce), a widely used surrogate for actinide metals, enables mechanistic studies of reactions in complex gas environments under controlled and safer laboratory conditions. Here, the oxidation behavior of Ce in H2O‐N2 mixed atmospheres was investigated from 200°C to 350°C using in situ thermogravimetry–mass spectrometry, in situ X‐
