Journal ArticleDOI
A Highly Reversible Mechanochromic Difluorobenzothiadiazole Dye with Near-Infrared Emission.
Jianhua Chen,Dongyang Li,Weijie Chi,Guotao Liu,Sheng Hua Liu,Xiaogang Liu,Chun Zhang,Jun Yin +7 more
TL;DR: A difluorobenzothiadiazole-based fluorescent material that exhibits a reversible mechanofluorochromic characteristic in the solid state switches to near-infrared fluorescence upon mechanical stimulation, but recover after fuming the ground solid powder with dichloromethane.
Journal ArticleDOI
Optical multiplexing: Tunable lifetime nanocrystals
Renren Deng,Xiaogang Liu +1 more
TL;DR: Tuning the luminescence lifetimes of upconversion nanocrystals through lanthanide doping provides new opportunities for optical multiplexing in the time domain for applications in imaging and security marking as mentioned in this paper.
Journal ArticleDOI
Static Magnetic Field Stimulation Enhances Oligodendrocyte Differentiation and Secretion of Neurotrophic Factors
Ankshita Prasad,Daniel Boon Loong Teh,Agata Blasiak,Chou Chai,Yang Wu,Payam Gharibani,In Hong Yang,In Hong Yang,Thang T. Phan,Kah-Leong Lim,Hyunsoo Yang,Xiaogang Liu,Angelo H. All +12 more
TL;DR: The ability of glial cells such as OPCs to positively respond to moderate intensity SMF stimulation by exhibiting enhanced differentiation, functionality as well as neurotrophic factor release is emphasized.
Journal ArticleDOI
Substantial Intramolecular Charge Transfer Induces Long Emission Wavelengths and Mega Stokes Shifts in 6-Aminocoumarins
TL;DR: In this article, the authors demonstrate that substantial intramolecular charge transfer (ICT) is responsible for the fluorescent properties of 6-aminocoumarins and reanalyzes the sensing mechanism of a 6-amino-couarmin-based fluorescent probe.
Journal ArticleDOI
Tuning the shape and thermoelectric property of PbTe nanocrystals by bismuth doping
Qian Zhang,Ting Sun,Feng Cao,Ming Li,Minghui Hong,Minghui Hong,Jikang Yuan,Qingyu Yan,Huey Hoon Hng,Nianqiang Wu,Xiaogang Liu +10 more
TL;DR: Thermoelectric investigation of these nanocrystals shows that the Bi(3+) doping increases electrical conductivity from 350 to 650 K and changes the Seebeck coefficient sign from positive to negative.
