    • 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 obert
      The 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 ...

    • Effects of site-occupation disorder on the low-temperature thermal conductivity of molecular crystals 

      Krivchikov, Alexander I; Vdovichenko, Georgii A.; Korolyuk, O. A.; Bermejo, F. Javier; Pardo Soto, Luis Carlos; Tamarit Mur, José Luis; Jezowski, Andrzej; Szewczyk, Daria (2015-01-01)
      Article
      Accés obert
      The thermal conductivity of CBrnCl4-n,(n = 0,1,2) and 2-adamantanone (C10H14O) crystals which exhibit substitutional disorder has been measured for temperatures between 2 K and 150 K. Such temperatures comprise signatures ...

    • 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 obert
      The 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 obert
      Disorder–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 ...

    • Influence of thermal treatment on thermal properties of adamantane derivatives 

      Szewczyk, Daria; Jezowski, Andrzej; Krivchikov, Alexander I; Tamarit Mur, José Luis (2015-05-01)
      Article
      Accés restringit per política de l'editorial
      Heat transport mechanisms present in 2-adamantanone and 1-cyanoadamantane crystals were investigated in a broad temperature range. To characterize scattering processes, thermal conductivity and heat capacity measurements ...

    • Polymorphism of 2-Adamantanone 

      Negrier, Philippe; Barrio Casado, María del; Romanini, Michela; Tamarit Mur, José Luis; Mondieig, Denise; Krivchikov, Alexander I; Kepinski, L.; Jezowski, Andrzej; Szewczyk, Daria (2014-05-07)
      Article
      Accés restringit per política de l'editorial
      The polymorphism of 2-adamantanone (C10H14O) has been investigated by means of X-ray diffraction and high-pressure thermal analysis. The intricate behavior of the low-temperature crystalline phases has been disentangled. ...

    • 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 obert
      We 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 ...
