A novel class of cationic gemini fluorosurfactants with different spacer and same hydrophobic chain were synthesized. They were structurally characterized by NMR (1H and 19F), FT-IR, ESI-MS and elemental analysis. The equilibrium surface tensions wer

A new method for temperature measurement is established based on the gray-body radiation, which can not only determine the real-time temperature of thermal source, but also conduct non-contacted temperature measurement with high precision. First, a w

Aiming at the shortage of the Raman spectra of drugs and the current situation of drug testing, we have applied Raman spectroscopic technique to several kinds of medicine, such as antibiotics, antihistamine, hemocoagulase and antiemetics. The spectra

Two-color stepwise excitation and photoionization schemes are adopted to study the spectra of bound even-parity high-lying states of the Sm atom with three different excitation paths via the 4f66s6p 7DJ (J=1, 2 and 3) intermediate states. In order to
