β¦ Synopsis
A device for highβaccuracy measurements of electric resistivity is introduced by the authors. Also, a layout for its use in highβtemperature experiments presented to record resistivity changes around the melting temperature. A demonstration of the apparatusβ precision (performed on steel samples at low temperature, with a deviation of merely 0.5 % from reference date) is given and first highβtemperature results are discussed.

An apparatus for measuring the pressure-volume-temperature (PVT) properties of polymers using a metal bellows has been developed at temperatures from 313 to 623 K and pressures up to 200 MPa. A calibration of the device was performed by measuring PVT of mercury and water. The experimental uncertaint
We have studied by Raman spectroscopy the thermal behavior of associated polyguanylic acid [poly(G)] and polyguanylic-polycytidylic acid [poly(G) β poly(C)] in self-pressurized aqueous solutions contained in sealed capillary tubes. The associated polynucleotides were found to be very resistant to he
