Journal ArticleDOI
Thermal conductivity of multiwalled carbon nanotubes
Da Jiang Yang,Qing Zhang,George C. K. Chen,Soon Fatt Yoon,J. Ahn,S. G. Wang,Qifa Zhou,Qi Jie Wang,Jingqi Li +8 more
TL;DR: The average thermal conductivity of carbon nanotube films, with the film thickness from 10 to 50 µm, is around 15 W/m K at room temperature and independent of the tube length.
Journal ArticleDOI

Huang,Hua Gong,Shubha Bhaskaran,Yue Gu,Mitsutoshi Makihata,Yuxuan Guo,Yusheng Lei,Yimu Chen,Chunfeng Wang,Chunfeng Wang,Yang Li,Tianjiao Zhang,Zeyu Chen,Albert P. Pisano,Liangfang Zhang,Qifa Zhou,Sheng Xu +25 more
TL;DR: The design and operation of an ultrasonic device that is conformal to the skin and capable of capturing blood pressure waveforms at deeply embedded arterial and venous sites is described, which enables the non-invasive, continuous and accurate monitoring of cardiovascular events from multiple body locations.
Journal ArticleDOI
Simultaneous functional photoacoustic and ultrasonic endoscopy of internal organs in vivo
Joon-Mo Yang,Christopher P. Favazza,Ruimin Chen,Junjie Yao,Xin Cai,Konstantin Maslov,Qifa Zhou,K. Kirk Shung,Lihong V. Wang +8 more
TL;DR: In this article, the authors presented simultaneous photoacoustic and ultrasonic dual-mode endoscopy and show its ability to image internal organs in vivo, thus illustrating its potential clinical application.
Journal ArticleDOI
3D-Printed Biomimetic Super-Hydrophobic Structure for Microdroplet Manipulation and Oil/Water Separation.
TL;DR: The results show that the 3D-printed eggbeater structure could have numerous applications, including water droplet manipulation, 3D cell culture, micro reactor, oil spill clean-up, and oil/water separation.
Journal ArticleDOI
Piezoelectric films for high frequency ultrasonic transducers in biomedical applications
TL;DR: The current status of the piezoelectric films and recent progress in the development of high frequency ultrasonic transducers will be discussed, and the recent developments in the high frequency transducers and arrays with piez Zoelectric ZnO and PZT thick film using MEMS technology are presented.
