Pinus armandii ectomycorrhizas mobilize aluminium‐bound phosphorus via carboxylates along a subtropical altitudinal gradient

open access: yesJournal of Ecology, Volume 114, Issue 8, August 2026.
Ectomycorrhizal roots of Pinus armandii release more carboxylates than non‐mycorrhizal root segments, mobilizing Al‐bound inorganic P. Under the lowest available P conditions, they also secrete more phosphatase, promoting the mineralization of Al‐bound organic P.

内电解—MBR工艺处理制药废水的研究

open access: yesGongye shui chuli, 2006
采用内电解—MBR工艺对制药废水进行处理研究,内电解法作为预处理主要降低有机污染物污染负荷,同时可以转化难降解有机物抑制的毒性,提高废水的可生化性。MBR工艺具有污泥浓度高、抗冲击负荷能力强、降解充分、降解速率高,对难降解物质也可使之分解去除的特点。通过试验研究得出在原水COD为12000mg/L左右时,内电解对该废水COD去除率可达40%左右,MBR的出水可使COD<300mg/L。

Spatiotemporally Adaptive Bilayer Silk Fibroin–Polyvinyl Alcohol–Metformin Composite Coating on Biodegradable Zinc for Orthopedic Applications

open access: yesRare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Biodegradable zinc (Zn)‐based materials are considered promising candidates for orthopedic applications because of their favorable mechanical properties, controllable biodegradability, and good biosafety profiles. However, their clinical translation is limited by early‐stage corrosion‐induced cytotoxicity and inflammation, as well as ...

Thermite‐Synthesized Fe–Ti–Al–Mg High‐Entropy Intermetallic Compound for Efficient Azo Dye Degradation

open access: yesRare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Most high‐entropy alloys (HEAs) tailored for contaminant degradation suffer from complex fabrication processes and high‐cost alloy design. Furthermore, low‐cost active elements such as Fe and Mg cannot be readily alloyed into HEAs via conventional routes.

In Situ Investigation on the Roles of Microstructural Characteristics in Fatigue Anisotropy and Crack Propagation of LPBF–IN718 Alloy

open access: yesRare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Laser powder bed fusion (LPBF) of Inconel 718 alloy inevitably introduces pronounced microstructural anisotropy, typified by columnar grains and robust crystallographic texture. This results in direction‐dependent fatigue behavior, raising critical reliability concerns for high‐stakes aerospace applications.

高浓度难降解有机工业废水处理技术评价

open access: yesGongye shui chuli, 2004
对高浓度难降解有机工业废水两类主要处理工艺的最新进展进行了综述和评价,一种是采用化学氧化和催化氧化为主的工艺;另一种是先预处理改变BOD/COD比值,然后再采用生化法处理工艺。经过分析,根据大多数高浓度难降解有机工业废水的特点,指出对“物化(混凝)-兼氧/缺氧/厌氧-好氧”工艺的各个环节进行研究是未来1~5a高浓度难降解有机工业废水处理技术的发展方向。并进一步指出针对高浓度难降解有机工业废水的专用混凝设备这一研究较少的领域,研制经济实用的强化混凝设备 ...

Ultrathin MnO2‐PEG‐PD‐L1 Nanosheets Enable Tumor Microenvironment Modulation and NIR‐II Photothermal Immunotherapy for Durable Control of Lung Cancer and Postoperative Recurrence

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Lung cancer is one of the most common and deadly malignancies worldwide. Although immune checkpoint inhibitors, including PD‐1/PD‐L1 blockers, have benefited a subset of patients, response rates remain limited, and recurrence is frequent because of the immunosuppressive tumor microenvironment (TME), characterized by hypoxia and dysregulated ...

Individual Uncertainty and Policy Compliance During the COVID‐19 Pandemic

open access: yesRisk, Hazards &Crisis in Public Policy, Volume 17, Issue 2, June 2026.
ABSTRACT Ample scholarship examines the extent to which public policies in representative democracies reflect the priorities and needs of the public, often finding that individuals are unaware of many policy issues and policy responses. This may be especially true when issues of risk and scientific uncertainty are involved, which can be difficult for ...

Superior Abrasibility of YSZ(ESP)/BN@ZrO2‐Polyester Composite Sealing Coating Reinforcing With Hybrid Micron/Nanometer Multiscaled Pore Structure

open access: yesRare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT Composite materials hold significant potential for abrasive sealing, yet composite materials used for abrasive sealing fall short in service durability under extreme environments. Here, a controllable strategy for adjusting pore structure is proposed, aiming to design a YSZ(ESP)/BN@ZrO2‐polyester coating with hybrid micron/nanometer ...
