Pyrene‐Capped Conjugated Amorphous Starbursts: Synthesis, Characterization, and Stable Lasing Properties in Ambient Atmosphere

18.06.2015 | Weidong Xu, Jianpeng Yi, Wen‐Yong Lai, Li Zhao, Qi Zhang, Wenbo Hu, Xin‐Wen Zhang, Yi Jiang, Ling Liu, Wei Huang, Advanced Functional Materials, 2015

A family of trigonal starburst conjugated molecules (TrFPy, TrFPy, and TrF2Py) composed of a truxene core and pyrene cappers with various bridge lengths is synthesized and characterized. The incorporation of pyrene cappers successfully depress the crystallization tendency, resulting in enhanced ...

Sensors, Vol. 15, Pages 14286-14297: A Room Temperature H2 Sensor Fabricated Using High Performance Pt-Loaded SnO2 Nanoparticles

17.06.2015 | Wang, Sheng-Chang ; Shaikh, Muhammad Omar, Sensors, 2015

Highly sensitive H2 gas sensors were prepared using pure and Pt-loaded SnO2 nanoparticles. Thick film sensors (~35 μm) were fabricated that showed a highly porous interconnected structure made of high density small grained nanoparticles. Using Pt as catalyst improved sensor response and reduced ...
