| Abstract: | The entropy and volume changes at the N-I transition have been determined in two binary systems (80CB-60CB and 8OCB-CBOOA). We give evidence for an anomaly of ΔVNI as a function of the concentration directly related to dT/dP]NI at P = 1 atm. This result might be due to the influence of a critical smectic-like compacity. |
