Preserving Proteins Under High Pressure and Low Temperature
Our group has a continuing interest in devising new freezing-protection agents. To this end, we have systematically investigated the structure of aqueous electrolyte salt solutions and room-temperature ionic liquids (RTILs), which consist of the cations and anions. We found that such water-mixed solutions remain liquid even at 1.0 GPa and 77 K (achieved by rapid cooling at 500 K/min) (Imai et a...
متن کاملLow-Background Temperature Calibration of Infrared Blackbodies
The stability of blackbody sources and their ability to be modeled accurately make them well suited for radiometric calibration activity. However, the implementation of the blackbody in industry or the laboratory may, and often does result in blackbody performance that deviates from ideal. The Low Background Infrared (LBIR) facility at the National Institute of Standards and Technology (NIST) w...
متن کاملLow-temperature olivine rheology at high pressure
San-Carlos olivine rheology was investigated at pressure (P) up to 9 GPa and temperature (T) lower than 890 ◦C. Six powder specimens were cold compressed and sintered into dense and compact materials, then deformed during relaxation experiments carried out at constant pressure and temperature in DIA-type cubic-anvil apparatus. Sample elastic strain was monitored during relaxation by in situ X-r...
متن کاملMicromechanical cohesion force between gas hydrate particles measured under high pressure and low temperature conditions.
To prevent hydrate plugging conditions in the transportation of oil/gas in multiphase flowlines, one of the key processes to control is the agglomeration/deposition of hydrate particles, which are determined by the cohesive/adhesive forces. Previous studies reporting measurements of the cohesive/adhesive force between hydrate particles used cyclopentane hydrate particles in a low-pressure micro...
متن کاملPhase changes of CO2 hydrate under high pressure and low temperature.
High pressure and low temperature experiments with CO(2) hydrate were performed using diamond anvil cells and a helium-refrigeration cryostat in the pressure and temperature range of 0.2-3.0 GPa and 280-80 K, respectively. In situ x-ray diffractometry revealed that the phase boundary between CO(2) hydrate and water+CO(2) extended below the 280 K reported previously, toward a higher pressure and...
