Anomalous and Colossal Thermal Expansion, Photoluminescence, and Dielectric Properties in Lead Halide-Layered Perovskites With Cyclohexylammonium and Cyclopentylammonium Cations
Cuquejo-Cid, Alberto; García-Fernández, Alberto; Popescu, Catalin; Bermúdez-García, Juan Manuel; Señarís-Rodríguez, M. A.; Castro-García, Socorro; Vázquez, Digna; Sánchez-Andújar, Manuel (Elsevier, 2022-06-03)[Abstract] A detailed study of lead halide-layered perovskites with general formula A2PbX4 (where A is cyclohexylammonium (CHA) or cyclopentylammonium (CPA) cation and X is Cl− or Br− anion) is presented. Using variable ... -
Coexistence of magnetic and electrical order in the new perovskite-like (C3N2H5)[Mn(HCOO)3] formate
Pato Doldán, Breogán; Gómez Aguirre, Lilián Claudia; Bermúdez-García, Juan Manuel; Sánchez-Andújar, Manuel; Fondado Fondado, Alfonso; Mira Pérez, Jorge; Castro-García, Socorro; Señarís-Rodríguez, M. A. (The Royal Society of Chemistry, 2013-09)[Abstract] In this work we further the structural characterization of the recently discovered (C3N2H5)[Mn(HCOO)3] metal–organic framework with perovskite-like structure, and we present its magnetic and dielectric properties ... -
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 ... -
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 ... -
Near-Room-Temperature Reversible Giant Barocaloric Effects in [(CH₃)₄N]Mn[N₃]₃ Hybrid Perovskite
Salgado-Beceiro, Jorge; Silva, Ariel Nonato Almeida de Abreu; Silva, Rosivaldo Xavier da; García-Fernández, Alberto; Sánchez-Andújar, Manuel; Castro-García, Socorro; Stern-Taulats, Enric; Señarís-Rodríguez, M. A.; Moya, Xavier; Bermúdez-García, Juan Manuel (Royal Society of Chemistry, 2020-09-25)[Abstract] We report giant reversible barocaloric effects in [(CH₃)₄N]Mn[N₃]₃ hybrid organic–inorganic perovskite, near its first-order cubic-monoclinic structural phase transition at 𝑇₀ ∼ 305 K. When driving the transition ... -
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 ... -
