荒漠区齿肋赤藓(Syntrichia caninervis Mitt)对微生境差异的生态与生理生化适应性
, 2015 齿肋赤藓(Syntrichia caninervis Mitt)广泛分布于世界干旱和半干旱荒漠地区，是典型的耐旱藓类。同时，齿肋赤藓也是古尔班通古特沙漠生物土壤结皮中的优势藓类植物，能够在多种微生境下良好生长，对荒漠生态系统稳定性与功能多样性具有重要作用。荒漠藓类植物叶片仅具一层细胞，对环境条件的变化十分敏感。古尔班通古特沙漠夏季炎热干燥，冬、春季降雪频繁，并能形成稳定的积雪层。然而，藓类植物如何适应这种夏季极端高温干燥、冬季极端低温以及早春地表反复冻融交替过程等环境的剧烈变化，相关的研究还鲜见报道 ...

, 2009 基因工程微生物口服治疗，是一种潜在的蛋白类药物口服给药方式，但是该给药方式存在着安全性的不足等问题。微囊化基因工程微生物口服治疗在很大程度上克服了上述问题。因此，本论文采用价格低廉生物相容性良好的天然高分子材料——壳聚糖作为微胶囊成膜材料，海藻酸钠作为囊心材料，以酿酒酵母和具有尿素代谢功能的基因工程大肠杆菌E.coli DH5a为模型菌株，制备载基因工程微生物的海藻酸钠-壳聚糖（AC）微胶囊进行口服治疗的可行性研究。 考察了壳聚糖作为口服微胶囊膜材料的可行性 ...

Harnessing Trace Elements: Novel Radiosensitization Strategies for Enhanced Cancer Radiotherapy
Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Radiotherapy (RT) is one of the core methods of comprehensive cancer treatment. Globally, more than 40% of cancer patients rely on radiotherapy to achieve tumor control, cure or palliative relief. However, radiation resistance, immunosuppression and normal tissue injury limit its clinical application.

, 2014 微胶囊化是提高益生菌产品在发酵、生产、货架期及胃肠道内投递过程中菌体活率的有效手段。然而，工业生产中广泛采用的喷雾干燥等微囊制备方法由于极端温度造成菌体活性保持困难；锐孔挤压法无法实现规模化生产；复凝聚法工艺复杂且成本较高。因此，在保证菌体活性的前提下，乳化法由于具有工艺简单、易于放大、微囊制备条件温和、凝胶微球球形度及强度好等优点，成为了益生菌微胶囊工业化的另一可行方法。首先，通过工艺优化建立了乳化-外部凝胶化工艺。对乳化-外部凝胶化与乳化-内部凝胶化工艺的比较及对凝胶形成机制的分析，证明乳化 ...

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT The development of lightweight, high‐attenuation, and broadband carbon‐based electromagnetic wave absorbers is hindered by the intrinsic trade‐off between impedance matching and dielectric dissipation. Herein, we report a facile and scalable synthesis of N‐doped lignin‐derived interconnected porous carbon (Nx‐LIPC) via hydrogen‐bond self ...
