Abstract:Experiments were carried out with a HP differential scanning calorimeter (DSC) and a HP thawing apparatus using frozen agar gel (3%, w/w) and Atlantic salmon (Salmo salar). Small samples (0.54-0.7g) were prepared for HP calorimetric tests. Frozen samples of cylindrical agar gel (47.5mm diameter, 135mm length) and plate salmon muscle (20mm thick) were subjected to water immersion thawing (WIT) (20°C) and HP thawing at 100, 150 and 200 MPa with water (20°C). Phase transition temperature of agar gel was close to phase diagram of pure water. Melting temperature of salmon was generally lower than phase diagram of pure water probably due to the presence of solutes and cellular structures in fish. HP DSC tests demonstrated a good correlation between temperature (T) and average pressure (P): T = -1.22-0.0946P-0.000115P2 (R2=0.99, n=10). For agar gel thawing time was 50.3±2.7, 36.4±2.2 and 30.8±1.8min, or 73, 53 and 45% of WIT time (68.7±4.3min) at 100, 150 and 200 MPa, respectively. For fish thawing time was 26.6±2.1, 22.6±1.4, 18.1±1.4 and 17.0±1.3 min for WIT, HPT at above pressures, respectively. | |||

Abstract:The directional growth experiments of graphite-like structured MoS2 crystallites have been conducted by utilizing a designed sample cell assembly under high pressure (2.0 and 5.0 GPa) and high temperature (700 oC). X-ray diffraction (XRD) and scanning electron microscope (SEM) are used to characterize the samples. The results show that the prepared nanocrystalline MoS2 (n-MoS2) crystals have a hexagonal layered structure. The crystal is uncovered to grow preferentially along the (002) plane, indicating that the low-energy surface is the (002) plane of the crystal. The striking diffuse/broadening nature of Bragg reflection is also analyzed in details, and considered to be associated with the defect structures of the layers stacking and rotational disorder. Measurements of crystallite/grain size are performed by using XRD technique and SEM observation. The measurement results suggest that the traditional peak broadening analysis techniques, including Williamson-Hall formula and Scherrer equation, may not be suitable for the present poorly crystallized n-MoS2 situation. The results may be conducive to have an insight into the growth mechanism and defects analysis of the layer-structured materials. | |||

Abstract:This work presents an experimental study on LiAlO2 at pressure up to 5.0 GPa at 389 K by using large-volume static high-pressure technology. X-ray diffraction analysis shows that a pressure-induced grain size reduction in LiAlO2 has been observed. The grain size reduces from ~70 nm to ~ 20 nm after high-pressure treatment. It has the implications to the high-pressure behavious of LiAlO2 and the synthesis of nano-scale materials under high pressure. | |||
