    • Dicyanamide-Perovskites at the Edge of Dense Hybrid Organic–Inorganic Materials 

      García Ben, Javier; McHugh, Lauren Nicole; Bennett, Thomas Douglas; Bermúdez-García, Juan Manuel (Elsevier, 2021-12-24)
      [Abstract] Hybrid organic–inorganic ABX3 perovskites with dicyanamide-ligands (dca: [N(CN)2]−) on the X-site are emerging as a distinct group of materials courtesy of their multifunctional properties. Here we present an ...

    • Discovery of Colossal Breathing-Caloric Effect under Low Applied Pressure in the Hybrid Organic–Inorganic MIL-53(Al) Material 

      García Ben, Javier; López-Beceiro, Jorge; Artiaga, Ramón; Salgado-Beceiro, Jorge; Delgado Ferreiro, Ignacio; Kolen'ko, Yury V.; Castro-García, Socorro; Señarís-Rodríguez, M. A.; Sánchez-Andújar, Manuel; Bermúdez-García, Juan Manuel (American Chemical Society, 2022-03-30)
      [Abstract] In this work, “breathing-caloric” effect is introduced as a new term to define very large thermal changes that arise from the combination of structural changes and gas adsorption processes occurring during ...

    • Empowering CO2Eco-Refrigeration With Colossal Breathing-Caloric-Like Effects in MOF-508b 

      Gelpi Santos, María; García Ben, Javier; Rodríguez-Hermida, Sabina; López-Beceiro, Jorge; Artiaga, Ramón; Baaliña Insua, Alvaro; Romero Gómez, Manuel; Romero Gómez, Javier; Zaragoza, Sonia; Salgado-Beceiro, Jorge; Walker, Julian; McMonagle, Charles James; Castro-García, Socorro; Sánchez-Andújar, Manuel; Señarís-Rodríguez, M. A.; Bermúdez-García, Juan Manuel (Wiley, 2024)
      [Abstract] Today,≈20% of the electric consumption is devoted to refrigeration; while,≈50% of the final energy is dedicated to heating applications. In this scenario,many cooling devices and heat-pumps are transitioning ...

    • Innovative materials chemistry strategies for engineered-enhanced thermomaterials for barocaloric and related solid-state refrigeration 

      García Ben, Javier (2023)
      [Abstract] The present PhD Thesis focuses on the search of new thermomaterials (materials that have large latent heat associated to a solid-solid phase transition), specifically hybrid organic-inorganic materials, with the ...

    • Narrowing the Tolerance Factor Limits for Hybrid Organic-Inorganic Dicyanamide-Perovskites 

      García Ben, Javier; García-Fernández, Alberto; Dafonte Rodríguez, Pedro; Delgado Ferreiro, Ignacio; Cappel, Ute; Castro-García, Socorro; Sánchez-Andújar, Manuel; Bermúdez-García, Juan Manuel; Señarís-Rodríguez, M. A. (Elsevier, 2022-10-11)
      [Abstract] In this work we focus in setting the limits of the tolerance factor and the size of the A-cations that stabilize the perovskite structure in hybrid dicyanamide compounds [A][Mn(dca)3]. For this purpose, we propose ...

    • Simple and Low-Cost Footstep Energy-Recover Barocaloric Heating and Cooling Device 

      García Ben, Javier; Delgado Ferreiro, Ignacio; Salgado-Beceiro, Jorge; Bermúdez-García, Juan Manuel (MDPI, 2021-10-10)
      [Abstract] In this work, we design, build, and test one of the very first barocaloric devices. The here presented device can recover the energy generated by an individual’s footstep and transform it into barocaloric heating ...

    • Structural, Thermal and Functional Properties of a Hybrid Dicyanamide-Perovskite Solid Solution 

      García Ben, Javier; Salgado-Beceiro, Jorge; Delgado Ferreiro, Ignacio; Dafonte Rodríguez, Pedro; López-Beceiro, Jorge; Artiaga, Ramón; Castro-García, Socorro; Sánchez-Andújar, Manuel; Bermúdez-García, Juan Manuel; Señarís-Rodríguez, M. A. (MDPI, 2022-06-18)
      [Abstract]: In Solid-State Chemistry, a well-known route to obtain new compounds and modulate their properties is the formation of solid solutions, a strategy widely exploited in the case of classical inorganic perovskites ...

    • Structure and thermal property relationships in the thermomaterial di-n-butylammonium tetrafluoroborate for multipurpose cooling and cold-storage 

      García Ben, Javier; Bermúdez-García, Juan Manuel; Delgado Ferreiro, Ignacio; López-Beceiro, Jorge; Artiaga, Ramón; Castro-García, Socorro; Sánchez-Andújar, Manuel; Señarís-Rodríguez, M. A. (Royal Society of Chemistry, 2023-11-07)
      [Abstract]: Nowadays around 46% of food production around the world requires refrigeration, which is generally provided either by active vapour-compression (based on refrigerants with liquid–gas transitions) or passive ...
