In the two-phase region, evidence for the |t|2\u03b2 singularity in the coexistence-curve diameter has been detected, thus confirming the novel predictions of complete scaling theory for liquid-liquid criticality. In the one-phase region, an \u201cunusual\u201d negative sign for the amplitude of the |t|1 \u2212 \u03b1 singularity has been encountered for the first time in an upper critical solution temperature type of binary liquid mixture at atmospheric pressure. Mass density measurements have also been carried out to provide additional information related to such experimental finding, which entails an increase of the critical temperature Tc under an electric field.<\/jats:p>","DOI":"10.1063\/1.3607237","type":"journal-article","created":{"date-parts":[[2011,7,12]],"date-time":"2011-07-12T22:32:05Z","timestamp":1310509925000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":8,"title":["The critical behavior of the dielectric constant in the polar + polar binary liquid mixture nitromethane + 3-pentanol: An unusual sign of its critical amplitude in the one-phase region"],"prefix":"10.1063","volume":"135","author":[{"given":"Jan","family":"Leys","sequence":"first","affiliation":[{"name":"Katholieke Universiteit Leuven 1 Laboratorium voor Akoestiek en Thermische Fysica, Departement Natuurkunde en Sterrenkunde, , Celestijnenlaan 200D-bus 2416, B-3001 Leuven, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Patricia","family":"Losada-P\u00e9rez","sequence":"additional","affiliation":[{"name":"Katholieke Universiteit Leuven 1 Laboratorium voor Akoestiek en Thermische Fysica, Departement Natuurkunde en Sterrenkunde, , Celestijnenlaan 200D-bus 2416, B-3001 Leuven, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jacobo","family":"Troncoso","sequence":"additional","affiliation":[{"name":"Universidad de Vigo (Campus de Ourense) 2 Departamento de F\u00edsica Aplicada, , As Lagoas s\/n, Ourense 32004, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christ","family":"Glorieux","sequence":"additional","affiliation":[{"name":"Katholieke Universiteit Leuven 1 Laboratorium voor Akoestiek en Thermische Fysica, Departement Natuurkunde en Sterrenkunde, , Celestijnenlaan 200D-bus 2416, B-3001 Leuven, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jan","family":"Thoen","sequence":"additional","affiliation":[{"name":"Katholieke Universiteit Leuven 1 Laboratorium voor Akoestiek en Thermische Fysica, Departement Natuurkunde en Sterrenkunde, , Celestijnenlaan 200D-bus 2416, B-3001 Leuven, Belgium"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"317","published-online":{"date-parts":[[2011,7,12]]},"reference":[{"key":"2023080306472881300_c1","doi-asserted-by":"publisher","first-page":"041121","DOI":"10.1103\/PhysRevE.81.041121","volume":"81","year":"2010","journal-title":"Phys.
