In this work, we have fabricated a series of perovskite-type oxide LaFeO<sub>3</sub> samples using simple sol–gel method and further calcination treatment.
In situ characterization of phase transitions and direct microscopic observations a low-melting ionic liquid, 1-butyl-3-methyl imidazolium tetrafluoroborate ([BMIM][BF(4)]), has been performed in detail by Raman spectroscopy. Compression [BMIM][BF(4)] was measured under hydrostatic pressure up to ~30.0 GPa at room temperature using high-pressure diamond anvil cell. With increasing, the characteristic bands displayed nonmonotonic pressure-induced frequency shifts, it is found undergo four...
Behavior of the phase transition an ionic liquid, [Cn-mim][PF6], has been investigated under pressures up to 1.0 GPa by using a high-pressure differential thermal analysis (DTA) apparatus. The T versus P diagrams [BMIM][PF6] and [EMIM][PF6] are constructed. DTA curve shows one endothermal valley in heating course at each given pressure, which indicates that simple from solid liquid taken place high pressure melting point is increase function pressure. However, two valleys within tested...
Melts of polyether-ether-ketone (PEEK) with three kinds average molecular weight are solidified by rapid compression from 0.1 to 2.0 GPa at 360 °C within 20 ms, and comparative samples also made quenching slow cooling the same melts. Through XRD DSC analyses mechanical tests recovered samples, it is found that bulk materials PEEK obtained exhibit a single amorphous phase unique properties such as high thermodynamic stability, excellent friction wear behaviour, considerable stiffness,...
Thermal-photo-oxidative coupled aging, anaerobic and thermal-oxidative aging testing were conducted on styrene-butadiene-styrene (SBS) type copolymer -modified asphalt at different temperatures. The changes in functional group index before after of modified deeply analyzed by the attenuated total reflection (ATR) method Fourier transform infrared (FTIR) spectroscopy. results show that carbonyl IC=O, sulfoxide IS=O, polybutadiene IPB, polystyrene IPS can properly characterize microscopic...
Eu3+ ions doped bismuth vanadate powders were synthesized by a hydrothermal method, and the effect of doping on crystal structure was investigated X-ray diffraction (XRD), Raman, UV–vis diffuse reflectance spectra. XRD Raman results reveal that solubility in fergusonite-BiVO4 is extremely small. Above 0.5 mol % doping, structural transition from fergusonite to zircon occurs. This phase band gap enhancement thus limits its photocatalytic performance. Upon compression, zircon-BiVO4:Eu3+ not...

In situ solidification of 1-ethyl-3-methylimidazolium ethyl sulfate [EMIM][EtOSO3] from melt under high pressure has been investigated by using Raman spectroscopy. The results indicate that might experience a phase transition at about 2.4 GPa upon compression, which could be identified as to superpressurized glass broadening the sharp ruby R1 fluorescence line. Upon cooling, it solidifies glassy state rather than crystallizes low temperature down 93 K. These facts are suggestive liquid...
