![]() This understanding helps us to design more efficient optical limiting materials and understand the intrinsic nonlinear optical properties of nanomaterials. Photo-thermal bubble scattering is not a nonlinear optical process and requires very low laser intensity. Yunfeng Zhu, Fan Feng, Jiyun Yu, Bin Song, Mingming Hu, Xudong Gao,Yue Wang, and Qing Zhang. A new tumor suppressor LncRNA ADAMTS9-AS2 is regulated by DNMT1 and inhibits migration of glioma cells. Design: A nationally representative retrospective study. His main research directions include: the application. Objectives: To develop a model of in-hospital mortality using medical record front page (MRFP) data and assess its validity in case-mix standardisation by comparison with a model developed using the complete medical record data. In situ Raman scattering of graphene further confirms that the temperature of graphene under laser pulses rises above the boiling point of water but still remains too low to vaporize graphene and create graphene plasma bubbles. Yunfeng Liu Guangzhou University Shigui Ruan University of Miami Jianshe Yu Guangzhou University Abstract In this paper we formulate a seasonally interactive model between closed season and open season with Michaelis-Menten type harvesting based on some management and capture methods of renewable resources. Jie Yao, Baosheng Zhou, Jian Zhang, Peiliang Geng,Kang Liu,Yunfeng Zhu, Weijie Zhu. I have profound and solid academic accomplishment in the fields of optical fiber sensing, nano / biophotonics and optical nonlinear dynamics. This conclusion is based on the direct observation of bubbles above the laser beam as well as a strong correlation between laser-induced ultrasound and optical limiting. Using graphene as an example, we show that photo-thermal microbubbles are responsible for optical limiting as strong light scattering centers: graphene sheets absorb incident light and become heated up above the boiling point of water, resulting in vapor and microbubble generation. However, the underlying mechanism has remained elusive and is generally ascribed to their superior nonlinear optical properties such as nonlinear absorption or nonlinear scattering. Liquid suspensions of carbon nanotubes, graphene and transition metal dichalcogenides have exhibited excellent performance in optical limiting. ![]()
