ABSTRACT In this paper, using the few-parametric equation of state, an approach is implemented to the calculation of the longitudinal and bulk sound speeds, as well as the elastic moduli of a number of isotropic metals behind the front of a strong shock wave. The results of theoretical calculations for aluminum are compared with the available shock impact experimental data. A new analytical approximation of the dependence of the Poisson's ratio on the pressure is proposed for metals. Non-monotonic dependence of the shear modulus for uranium on the pressure and temperature in view of the melting behind the shock front is determined.

ABSTRACT We have modified zirconia-toughened alumina anvil geometry and systematically varied single-toroidal, encapsulated, Ti–Zr gasket dimensions, exploring the resulting effects on pressure and maximum load performance, which have been measured using a Paris–Edinburgh press. Reducing the curvature and depth of the recess at the rear of the anvil appears to permit repeated use of the anvils to higher loads, and a general trend indicates that thinner Ti–Zr gaskets may achieve higher pressures than thicker alternatives.

ABSTRACT The sound velocities of polycrystalline Mg-phase D were investigated at the pressure up to 13.6 GPa and room temperature, using ultrasonic interferometry in a multi-anvil apparatus. The P (VP ) and S (VS ) wave velocities obtained at ambient conditions produced the results of VP = 9.26(3) km/s and VS = 5.46(1) km/s. The results are in accordance with the values for Mg-phase D by Brillouin scattering (VP = 9.25 km/s and VS = 5.51km/s). The results, i.e. Ks0 = 153.8(13) GPa and G0 = 99.8(5) GPa obtained through two-dimensional linear fitting analysis are self-consistent with Ks0 = 153.3(16) GPa and G0 = 99.5(10) GPa derived by third-order Eulerian finite strain equations. We also find that Vp of phase D is 1.8–2.2% lower than Fe-ringwoodite, but Vs is higher than Fe-ringwoodite at the bottom of the mantle transition zone by up to 1.3%.

ABSTRACT A new experimental setup to continuously and automatically measure ultrasonic elastic wave velocities, X-ray radiography, and X-ray diffraction in large volume press is developed to explore structural change of amorphous materials at in situ high pressure and high temperature conditions. A continuous measurement for Zr50Cu40Al10 metallic glass is carried out during the heating process from 304 to 1102 K under high pressure conditions of 6.8–8.6 GPa. The sample length, elastic wave velocities, and Poisson’s ratio show marked changes at 611, 745, 825, and 874 K, which are interpreted as glass transition temperature (Tg ) at 611 K, two polyamorphic structural changes at 745 and 825 K, and crystallization above 874 K, respectively. We find that the 1.2Tg temperature (733 K at ∼8 GPa), where simulations study predicted occurrence of thermal rejuvenation, corresponds to the temperature of the polyamorphic structural change (745 K) in Zr50Cu40Al10 metallic glass.

ABSTRACT The high pressure structural changes of Cu3TeO6 have been investigated by using synchrotron radiation X-ray diffraction and Raman spectroscopy up to 23.2(4) and 45.9(7) GPa, respectively. It was found that Cu3TeO6 transformed from the cubic (Ia-3) structure to the orthorhombic (Ibca) structure around 8.6(1) GPa, and the phase transition was reversible. The phase transformation was subtle because of the similarity between two crystal structures. A large internal lattice strain could be the cause to the pressure-induced structural phase transition.

ABSTRACT In-situ X-ray diffraction measurements of ScOOH were conducted under high pressure and temperature conditions up to 11 GPa and 900 K to understand its phase transitions. As the pressure increased, α-ScOOH, InOOH-type ScOOH, and YbOOH-type ScOOH were observed. The experimental results indicate that the boundaries between α-ScOOH and InOOH-type ScOOH, and between InOOH-type and YbOOH-type ScOOH are represented by the following linear equations: P(GPa) = (0.0009 ± 0.0015) × [T(K) – 700] + 4.33 ± 0.04 and P(GPa) = (–0.0029 ± 0.0002) × [T(K) – 800] + 8.1 ± 0.3, respectively. By using a least-squares fit of the second-order Birch–Murnaghan equation of state (EoS) to the experimental compression data, the EoS parameters of the three phases of ScOOH at 400 K were obtained. The volume change of the transition from α-ScOOH to InOOH-type ScOOH is ∼3.9% at 4 GPa and 400 K, while the volume change of the transition from InOOH-type to YbOOH-type ScOOH is ∼7.6% at 9 GPa and 400 K.

ABSTRACT The sensitivity of Paenibacillus sp. and Terribacillus aidingensis spores to combined action of HP, nisin and moderate heating were investigated for the first time. The results showed that the effect of HP on spores varies with pressure level, treatment temperature, spore species and presence of nisin. T. aidingensis spores were more resistant than Paenibacillus sp., whatever the treatment applied. The inactivation rates of both spore species did not exceed 2.7log (CFU/mL) after HP treatment at 600 MPa/50°C/10 min. However, a high synergistic effect of nisin and HP was observed after a treatment at 500 MPa/10 min/50°C with addition of nisin during HP and into the recovery medium, leading to 6log (CFU/mL) and 4log (CFU/mL) reduction for Paenibacillus and Terribacillus spores, respectively. Finally, the fraction of germinated spores by HP was measured and the results showed that germination induction is not the only underlying mechanisms of nisin sensitization by HP.

ABSTRACT The indirect method of obtaining in situ particle velocity of sample, under dynamic high-pressure loading experiments, generates an error due to the influence of rarefaction wave from the sample-window interface. Using the spinel as a window is an attractive method to reduce the error due to the total impedance matching of sample and window in the loading experiments of the spinel. To explore the possibility of the spinel as a window, ramp wave compression experiments were conducted to determine the refractive index of loading longitudinal stress range below 15.9 GPa. The result showed smooth particle velocity curve and linear relationship between refractive index and density. The effect of temperature on refractive index can be negligible, proved by analyzing the effect of temperature on polarizability. It is indicated that the spinel can be used as a window for loading experiments of the spinel and similar impedance materials.

ABSTRACT Isostructural transitions have been reported to occur in several pure elements; however, most of these have been disproven. Zr is one of those elements which remains controversial with two reports of an isostructural bcc-to-bcc transition at ∼56–60 GPa at an ambient temperature and a more recent report proposing a second bcc-to-bcc transition at 110 GPa. Here, we report a detailed experimental and theoretical study of zirconium in the pressure region of the proposed isostructural transition(s). We conducted three room temperature static compression experiments using Ne as a pressure transmitting medium up to 80 GPa. We see no evidence for an isostructural transition finding a smooth compression curve for β-Zr. We determined the theoretical volume, elastic parameters, and Poisson’s ratio for β-Zr up to 717 GPa and no obvious anomalies are identified. Our new results join the growing body of evidence that does not find evidence of isostructural transitions in β-Zr.

ABSTRACT Chilled storage stability of marinated and high pressure treated peeled and undeveined Indian white prawns (Fenneropenaeus indicus) were studied. The prawns were marinated with condiments viz. chilli powder, salt and turmeric, and - vacuum packed in ethylene-vinyl alcohol copolymer pouches. Marinated unpressurized prawn samples were kept as control. The products were stored at 2 ± 1°C for evaluating - shelf life by analysing biochemical, microbiological and organoleptic parameters. Pressurization significantly altered the quality indices such as pH, total volatile basic nitrogen, free fatty acid, thiobarbituric acid, total plate count and overall acceptability of samples. The control and 200 MPa treated sample were rejected on 20th and 25th day of storage respectively, whereas 250 and 300 MPa treated samples achieved a shelf life of 35 days. Among the samples, the prawns treated at 250 MPa were found to be organoleptically superior with respect to its biochemical and microbiological quality parameters.

Marinated unpressurized prawn samples were kept as control. The products were stored at 2 ± 1°C for evaluating - shelf life by analysing biochemical, microbiological and organoleptic parameters. Pressurization significantly altered the quality indices such as pH, total volatile basic nitrogen, free fatty acid, thiobarbituric acid, total plate count and overall acceptability of samples. The control and 200 MPa treated sample were rejected on 20th and 25th day of storage respectively, whereas 250 and 300 MPa treated samples achieved a shelf life of 35 days. Among the samples, the prawns treated at 250 MPa were found to be organoleptically superior with respect to its biochemical and microbiological quality parameters.","PeriodicalId":12864,"journal":{"name":"High Pressure Research","volume":"27 1","pages":"341 - 351"},"PeriodicalIF":2.0,"publicationDate":"2021-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/08957959.2021.1957864","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59888357","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
