Study on Self-assembly Behavior and Multiple-stimuli-responsive Property of Azobenzene-based Amphiphilic Copolymers in Solution [PDF]
, 2016 环境响应聚合物分子链中含有特殊的响应基团，能够对外界环境的改变做出结构和性质的调整。许多科研团队致力于设计这类聚合物，并以此来丰富其在药物传送与释放方面的应用。偶氮苯由于有独特的光响应性和还原响应性，将其嵌入到聚合物中，通过光照或加入还原性物质便可调控其自组装聚集体的结构与实现药物分子的释放等，使其成为自组装领域的研究热点。本文先合成活性的偶氮苯单体，再将其与其他响应性单体通过RAFT法进行共聚，制备出含偶氮苯基团的多重刺激响应双亲共聚物，研究了共聚物的自组装行为、胶束的荧光及控制释放性能 ...

Luminescent Properties of Sr_(3-x)Si_(1-x)Al_xO_5:xCe--(3+) Phosphors Prepared by Heterogeneous Precipitation Method [PDF]
, 2012 采用非均相沉淀法制备了Sr3-XSI1-XAlXO5∶XCE3+荧光粉,并与高温固相法制备的该荧光粉进行了对比。以Xrd、SEM和荧光光谱分析来表征所制备的荧光粉。结果表明,非均相沉淀法比高温固相反应法制备的荧光粉相纯度更高,颗粒分布更窄,晶面清晰,团聚程度小,相对发光强度也更高。荧光粉的激发光谱为270~500 nM的双峰宽带,最强激发峰位于417 nM处。发射光谱为450~700 nM的单峰宽带,峰值位于525nM处。电荷补偿剂对荧光粉相对发光强度影响较大,外加Al3+置换SI4 ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Platinum (Pt)‐based catalysts are crucial for the commercialization of hydrogen/metal air batteries, but they suffer from Pt scarcity, high cost, and nanoparticle dissolution/agglomeration, mainly leading to performance degradation. We address this by synthesizing a PtFe alloy catalyst (PtFe–PA–NC) via a phytic acid (PA) assisted pyrolysis ...
