Advances in Elemene Nanodelivery Systems: From Material Design to Disease Treatment

open access: yesRare Metals, EarlyView.
ABSTRACT Elemene (ELE) is a bioactive sesquiterpenoid extracted from traditional Chinese herbs, demonstrating broad‐spectrum antitumor, anti‐inflammatory, and analgesic properties with significant therapeutic potential. However, its clinical utility is constrained by inherent physicochemical limitations, including volatility and hydrophobicity, which ...

京西地区老年男性煤工尘肺患者骨质疏松发病率的调查研究

open access: yesZhongguo shiyan zhenduanxue, 2014
煤工尘肺是煤矿工人常见的职业病,由于近年来医疗水平的不断提高,老年男性煤工尘肺患者的寿命明显延长,合并骨质疏松性骨折较常见,同时煤工尘肺导致心肺功能减退,且并存多种内科疾病,手术和麻醉的风险增高,骨折后的死亡率也增高[1]。多年来,在骨质疏松与相关疾病关系的研究中,较多的是骨质疏松(OP)与糖尿病、甲状旁腺等相关性的研究[2,3 ...

Composite‐Field Annealing Enables Superior High‐Temperature Noise Stability in Fluxgate Sensors With Co‐Rich Amorphous Microwires

open access: yesRare Metals, EarlyView.
ABSTRACT Fluxgate sensors with Co‐rich amorphous microwires, widely used for their low noise in magnetic field measurements, encounter significant challenges in high‐temperature environments such as well drilling and geological exploration. Prolonged thermal aging degrades the performance of Co‐rich amorphous microwires, resulting in increased noise ...

Band Edge Reorganization via Symmetry Constraints in Covalent Bonding Heterojunctions Boosts Photocatalytic Metronidazole Degradation

open access: yesRare Metals, EarlyView.
ABSTRACT The covalent bonds at heterojunction interfaces enable more efficient charge carrier separation than traditional weakly coupled heterojunctions, with enhanced photocatalytic performance for organic wastewater purification. The interfacial covalent bonds drive energy band reorganization, rendering the conventional independent band edge ...
