  • CBS SOP: Liquid Nitrogen AODA
    Liquid Nitrogen SOP Liquid Nitrogen SOP CBS-SOP-020-19 Effective: Mar 2019 Author: A. Holliss Edited: P. Scheffer Purpose To provide procedural guidance on the dispensing, transport, handling and disposal of liquid nitrogen. This document is to be used in addition to on the job training and not as a substitution. Scope All students and staff within CBS working with liquid nitrogen should be familiar with these procedures. Outside of normal working hours (weekdays 08:30 to 16:30) liquid nitrogen must not be dispensed from the pressurized storage vessel. If there is an absolute necessity for liquid nitrogen from the pressurized storage dewar at that time, this procedure must be carried out with the supervisor’s knowledge by two trained personnel working together to allow for the alarm to be raised if there is an incident/accident. The second ‘spotter’ person is to be in visual contact with the first ‘dispensing’ person but not so close to also be in danger. Definitions/Acronyms Cryogenic storage dewar – a specialized double-walled vacuum container used for storing cryogenic liquid and provides thermal insulation as the cryogenic liquid slowly boils away. Excessive pressure is released through an open top, vented cap or through a pressure relief valve to prevent the risk of explosion. Oxygen deficient atmosphere – an atmosphere with less than 19.5% oxygen by volume. Air normally contains approximately 21% oxygen. If gases other than oxygen are added or mixed with air, the oxygen concentration is reduced (diluted) and oxygen deficiency occurs. No human sense will give an indication of an oxygen-reduced atmosphere.

  • Cryoelectron Microscopy of a Nucleating Model Bile in Vitreous Ice: Formation of Primordial Vesicles
    1436 Biophysical Journal Volume 76 March 1999 1436–1451 Cryoelectron Microscopy of a Nucleating Model Bile in Vitreous Ice: Formation of Primordial Vesicles Donald L. Gantz,* David Q.-H. Wang,# Martin C. Carey,# and Donald M. Small* *Department of Biophysics, Boston University School of Medicine, Boston, Massachusetts 02118, and #Department of Medicine, Gastroenterology Division, Brigham and Women’s Hospital, Harvard Medical School and Harvard Digestive Disease Center, Boston, Massachusetts 02115 USA ABSTRACT Because gallstones form so frequently in human bile, pathophysiologically relevant supersaturated model biles are commonly employed to study cholesterol crystal formation. We used cryo-transmission electron microscopy, comple- mented by polarizing light microscopy, to investigate early stages of cholesterol nucleation in model bile. In the system studied, the proposed microscopic sequence involves the evolution of small unilamellar to multilamellar vesicles to lamellar liquid crystals and finally to cholesterol crystals. Small aliquots of a concentrated (total lipid concentration ϭ 29.2 g/dl) model bile containing 8.5% cholesterol, 22.9% egg yolk lecithin, and 68.6% taurocholate (all mole %) were vitrified at 2 min to 20 days after fourfold dilution to induce supersaturation. Mixed micelles together with a category of vesicles denoted primordial, small unilamellar vesicles of two distinct morphologies (sphere/ellipsoid and cylinder/arachoid), large unilamellar vesicles, multilamellar vesicles, and cholesterol monohydrate crystals were imaged. No evidence of aggregation/fusion of small unilamellar vesicles to form multilamellar vesicles was detected. Low numbers of multilamellar vesicles were present, some of which were sufficiently large to be identified as liquid crystals by polarizing light microscopy. Dimensions, surface areas, and volumes of spherical/ellipsoidal and cylindrical/arachoidal vesicles were quantified.

  • Benchmarking a Cryogenic Code for the FREIA Helium Liquefier
    FREIA Report 2020/01 July 9, 2020 Department of Physics and Astronomy Uppsala University Benchmarking a Cryogenic Code for the FREIA Helium Liquefier Elias Waagaard Supervisor: Volker Ziemann Subject reader: Roger Ruber Bachelor Thesis, 15 credits Uppsala University Uppsala, Sweden Department of Physics and Astronomy Uppsala University Box 516 SE-75120 Uppsala Sweden Papers in the FREIA Report Series are published on internet in PDF format. Download from http://uu.diva-portal.org Abstract The thermodynamics inside the helium liquifier in the FREIA laboratory still contains many unknowns. The purpose of this project is to develop a theoretical model and im- plement it in MATLAB, with the help of the CoolProp library. This theoretical model of the FREIA liquefaction cycle aims at finding the unknown parameters not specified in the manual of the manufacturer, starting from the principle of enthalpy conservation. Inspiration was taken from the classical liquefaction cycles of Linde-Hampson, Claude and Collins. We developed a linear mathematical model for cycle components such as turboexpanders and heat exchangers, and a non-linear model for the liquefaction in the phase separator. Liquefaction yields of 10% and 6% were obtained in our model simula- tions, with and without liquid nitrogen pre-cooling respectively - similar to those in the FREIA liquefier within one percentage point. The sensors placed in FREIA showed simi- lar pressure and temperature values, even though not every point could be verified due to the lack of sensors. We observed an increase of more than 50% in yield after adjustments of the heat exchanger design in the model, especially the first one.

  • Influence of the Freezing Process on Quality Retention of Frozen Tomato Slices
    Influence of the Freezing Process on Quality Retention of Frozen Tomato Slices THESIS Presented in Partial Fulfillment of the Requirements for the Degree Master of Science in the Graduate School of The Ohio State University By Qinfan Zhou Graduate Program in Food, Agricultural & Biological Engineering The Ohio State University 2016 Master's Examination Committee: Dr. Dennis R. Heldman, Advisor Dr. Sudhir K. Sastry Dr. Christopher Simons Copyrighted by Qinfan Zhou 2016 Abstract Tomato (Lycopersicon esculentum Mill.) is one of the most important economic plants worldwide. Frozen vegetables and fruits have gained popular nowadays. However, the fragile and complex structure of the tomato is very sensitive to ice crystal formation of water during phase change. The overall objective of this investigation was to optimize the freezing conditions required to achieve maximum retention of the quality attributes of frozen-thawed tomato slices. Fresh-cut Roma tomato were sliced into pieces with the thickness of 4.5 mm and pre-treated with CaCl2 solutions in concentrations ranging from 0.4 to 4.0 g/100g. The tomato slices were then frozen in either a dry-ice ethanol bath, liquid nitrogen or an air blast freezer to achieve a significant range of “time-to freeze”. The various cold media were used to reduce the geometric center temperature of the slices from 25℃ to -18°C. The frozen tomatoes slices were stored in freezer for temperature equilibration at -18 °C for 12 hours before thawing at ambient temperature for measurement of texture and mass loss. The results from the experimental measurements indicated that reducing the “time-to-freeze” (increasing freezing rates) was not sufficient to increase the hardness retention of tomato slices.

However, vibrational excitation of a cryogenic storage tank and the fluid inside it also play a role in the loss of cryogens. Mechanical energy applied to the system in the form of vibrational input is converted into thermal energy via viscous damping of the fluid.
