梯级水电站开发对香溪河悬浮颗粒物粒径及浓度的影响

, 2008
通过对香溪河悬浮颗粒物粒度及浓度的实验分析,研究梯级水电站开发对河流悬浮颗粒物的影响,结果表明:(1)香溪河干流悬浮颗粒物粒径由上游到中游逐渐减小,并且在无水电站干扰时颗粒物粒径减小幅度较大;(2)从进水口至出水口河段,水电站悬浮颗粒物粒径总体变化不显著;(3)水电站从进水口河段至出水口河段,总悬浮颗粒物浓度(CTPM)在某些位置有所增加,有机颗粒物浓度(CPOM)无明显变化 ...

Calcium‐Engineered Copper/Palladium Nanozyme With Reactive Oxygen Species/Nitric Oxide Dual‐Burst for Enhancing Immunotherapy via Multiple‐Inducing Calcium Overload

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Calcium overload‐induced immunogenic cell death (ICD) holds great potential in antitumor immunotherapy, and it is a critical strategy for regulating multiple intracellular Ca2+ channels through inhibiting the endogenous Ca2+ efflux and promoting the exogenous Ca2+ influx.

Carbon Nanorods With Adhered Monodisperse Cobalt Nanoparticles Exhibiting Electromagnetic Wave Absorption and Antibacterial Potential

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Magnetic particles coated with carbon shells have been considered as promising electromagnetic wave absorption materials with antibacterial features. However, how to precisely control the monodispersed magnetic nanoparticles on a carbon matrix to manipulate impedance matching and antibacterial performances is still a key challenge.

Tailoring the Mechanical Properties of L‐DED‐Fabricated γ‐TiAl Alloys Through Heat Treatment: Correlating Microstructural Evolution With Fracture Mechanisms

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Laser‐directed energy deposition (L‐DED) offers a flexible route for fabricating γ‐TiAl components, but the as‐deposited microstructure requires post‐processing to overcome limited deformation capability. Here, an L‐DED Ti–48Al–2Cr–2Nb alloy was subjected to solution and solution‐aging treatments.

煤矸石对盐碱土壤绿化和土壤微生物的影响

Shuitu Baochi Xuebao, 2018
为探究煤矸石对盐碱土壤绿化的改良效果和对土壤微生物的影响，将不同用量（0，10%，20%，30%，40%，50%）和不同粒径（小粒径5 mm，以及小中大粒径等比例的混合粒径）煤矸石施用于盐碱土壤，进行紫花苜蓿盆栽试验，测定紫花苜蓿株高、生物量以及土壤微生物量和酶活性指标。结果表明，不同粒径煤矸石处理的土壤微生物量碳氮，土壤的脲酶、过氧化氢酶、脱氢酶活性，以及紫花苜蓿株高、生物量均随着煤矸石用量的增加呈先增大后降低的趋势，混合粒径、小粒径、中粒径、大粒径煤矸石处理的盐碱土上述指标分别在20%，20%，30%

Overcoming Thermodynamic and Kinetic Constraints of Recrystallization and Precipitation in Cu‐Ni‐Sn Alloy via Electropulsing Treatment

Rare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT The performance optimization of ultrahigh‐strength Cu‐15Ni‐8Sn alloy relies on controlling recrystallization and aging precipitation, which are two thermally activated processes constrained by high activation barriers. Conventional heat treatment requires elevated temperatures and prolonged holding time, inevitably leading to grain coarsening ...
