Anomalous behavior of thermal conductivity at high temperatures for molecular crystals composed of flexible molecules
Horbat¿nko, Yuliia V.; Romantsova, Olesia O.; Korolyuk, Oksana A.; Jezowski, Andrzej; Szewczyk, Daria; Tamarit Mur, José Luis; Krivchikov, Alexander (2019-04-01)
Article
Accés obertThe temperature dependence of thermal conductivity ¿(¿) of selected molecular polycrystals consisting of flexible molecules was investigated within 20–260¿K. The materials were para-chloronitrobenzene, pentachloronitrobenzene ... -
Glassy Anomalies in the Low-Temperature Thermal Properties of a Minimally Disordered Crystalline Solid
Gebbia, Jonathan Fernando; Ramos, M. A.; Szewczyk, Daria; Jezowski, Andrzej; Krivchikov, Alexander; Horbatenko, Y.V; Guidi, T.; Bermejo, F. J.; Tamarit Mur, José Luis (2017-11-21)
Article
Accés obertThe low-temperature thermal and transport properties of an unusual kind of crystal exhibiting minimal molecular positional and tilting disorder have been measured. The material, namely, low-dimensional, highly anisotropic ... -
Heat capacity anomalies of the molecular crystal 1-fluoro-adamantane at low temperatures
Szewczyk, Daria; Gebbia, Jonathan Fernando; Jezowski, Andrzej; Krivchikov, Alexander; Guidi, T.; Cazorla Silva, Claudio; Tamarit Mur, José Luis (Nature, 2021-09-20)
Article
Accés obertDisorder–disorder phase transitions are rare in nature. Here, we present a comprehensive low-temperature experimental and theoretical study of the heat capacity and vibrational density of states of 1-fluoro-adamantane ... -
Low-Temperature Heat Capacity Anomalies in Ordered and Disordered Phases of Normal and Deuterated Thiophene
Miyazaki, Yuji; NAKANO, Motohiro; Krivchikov, Alexander; Gebbia, Jonathan Fernando; Cazorla Silva, Claudio; Tamarit Mur, José Luis (2021-03-04)
Article
Accés obertWe measured the specific heat Cp of normal (C4H4S) and deuterated (C4D4S) thiophene in the temperature interval of 1 = T, K = 25. C4H4S exhibits a metastable phase II2 and a stable phase V, both with frozen orientational ... -
Role of optical phonons and anharmonicity in the appearance of the heat capacity Boson peak-like anomaly in fully ordered molecular crystals
Krivchikov, Alexander; Jezowski, Andrzej; Szewczyk, Daria; Korolyuk, Oksana A.; Romantsova, Olesia O.; Buravtseva, Lubov M.; Cazorla Silva, Claudio; Tamarit Mur, José Luis (2022-06-02)
Article
Accés obertWe demonstrate that the heat capacity Boson peak (BP)-like anomaly appearing in fully ordered anharmonic molecular crystals emerges as a result of the strong interactions between propagating (acoustic) and low-energy ... -
Thermodynamic and kinetic fragility of Freon 113: the most fragile plastic crystal
Vispa, Alessandro; Romanini, Michela; Ramos, M. A.; Pardo Soto, Luis Carlos; Bermejo, F. J.; Hassaine, M.; Krivchikov, Alexander; Taylor, Jonathan; Tamarit Mur, José Luis (2017-03-10)
Article
Accés obertWe present a dynamic and thermodynamic study of the orientational glass former Freon 113 (1,1,2-trichloro-1,2,2-trifluoroethane, CCl 2 F-CClF 2) in order to analyze its kinetic and thermodynamic fragilities. Freon 113 ...
