Thermoelectric properties of Bi2Sr2Co2O9 whiskers under hydrostatic pressure
We report the temperature dependence of thermopower (S) in the ab plane of Bi2Sr2Co2O9 ~BC-222! single crystalline whiskers under high pressure up to 1.2 GPa. Special modifications were made to our high-pressure transport measurement system to improve the measurement accuracy of S for whiskers with high resistance. Pressure improved the contact resistance dramatically. We observed a slight decr...
متن کاملTransport Properties For Carbon Nanotubes Under Hydrostatic Pressure
Multi-wall carbon nanotubes (MWNTs) were mixed with polystyrene (PS) by 20 wt%, which is slightly above the percolation threshold. Temperature (T ) dependencies of Seebeck coefficient (S) and resistance (R) for the sample (MWNT-PS) were measured under hydrostatic pressure upto 1.2 GPa. The resistance at ambient pressure showed power law T -dependence (R ∝ T−α) and agreed well with Luttinger liq...
متن کاملPotency under pressure: the impact of hydrostatic pressure on antigenic properties of influenza virus hemagglutinin
BACKGROUND Influenza vaccines are effective in protecting against illness and death caused by this seasonal pathogen. The potency of influenza vaccines is measured by single radial immunodiffusion (SRID) assay that quantifies antigenic forms of hemagglutinin (HA). Hydrostatic pressure results in loss of binding of influenza virus to red blood cells, but it is not known whether this infers loss ...
متن کاملConformation of p-terphenyl under hydrostatic pressure.
The conformation of p-terphenyl (C18H14) and deuterated p-terphenyl (C18D14) has been investigated, using high-pressure infrared spectroscopy at liquid-helium temperatures. First-principles calculations, together with the experimental results, were performed to determine the structure of p-terphenyl in the twisted conformation. At low temperatures and pressures, p-terphenyl belongs to the C2 po...
متن کاملInfrared spectroscopy of biphenyl under hydrostatic pressure
Changes in the conformations of conjugated molecules affect the optical and electronic properties significantly. Hydrostatic pressure has been used to probe the conformations of biphenyl (C12H10) and deuterated biphenyl (C12D10) at liquid-helium temperatures. Infrared ~IR! spectra of these materials have been taken up to a pressure of 2 GPa. A disappearance of certain IR absorption peaks has be...
