Angewandte Chemie, Volume 136, Issue 41, October 7, 2024.Femtosecond infrared spectroscopy is used to study the out‐of‐equilibrium dynamics of the ultrafast and persistent photoinduced phase transition of the Rb0.94Mn0.94Co0.06[Fe(CN)6]0.98 ⋅ 0.2H2O material, induced at room temperature. The data show that optical excitation creates small CT polarons within 250 fs.

Advanced Materials Interfaces, Volume 12, Issue 21, November 10, 2025.This study showcases the airbrush method, a novel coating technique for the preparation of thin black paint coatings for infrared camera measurements. Using the method, coatings with an emissivity of 0.95, and as thin as 3 µm can be prepared. The method is affordable, non‐destructive, and can be prepared onto a wide range of substrates while ...

Giant barocaloric effects at low pressure in ferrielectric ammonium sulphate [PDF]
Nature Communications, 2015 AbstractCaloric effects are currently under intense study due to the prospect of environment-friendly cooling applications. Most of the research is centred on large magnetocaloric effects and large electrocaloric effects, but the former require large magnetic fields that are challenging to generate economically and the latter require large electric ...

Colossal barocaloric effects in adamantane derivatives for thermal management
APL Materials, 2022 Plastic crystals are currently attracting interest because their solid-state caloric functionality could be used to tackle climate change in two critical areas: (i) more environmentally friendly cooling and heating driven by pressure and (ii) passive waste heat management.

Frustrated magnetism and caloric effects in Mn-based antiperovskite Nitrides : Ab Initio theory [PDF]
, 2017 We model changes of magnetic ordering in Mn-antiperovskite nitrides driven by biaxial lattice strain at zero and at finite temperature. We employ a non-collinear spin-polarised density functional theory to compare the response of the geometrically ...

Chemistry – A European Journal, Volume 31, Issue 60, October 27, 2025.The impact of X‐ray damage in chemical crystals was minimised by the introduction of area detectors in the late 20th‐century. Now, ever‐brighter X‐ray sources are re‐establishing X‐ray damage as a key challenge. This article reviews recent observations of X‐ray‐induced processes in chemical samples and discusses state‐of‐the‐art methodologies for their

Magneto- and Baro- Caloric Responses in Magnetovolumic Systems
, 2015 By means of a mean-field model extended to include magnetovolumic effects we study the effect of external fields on the thermal response characterized either by the isothermal entropy change and/or the adiabatic temperature change. The model includes two

Ultrastable glasses portray similar behaviour to ordinary glasses at high pressure [PDF]
, 2016 Pressure experiments provide a unique opportunity to unravel new insights into glass-forming liquids by exploring its effect on the dynamics of viscous liquids and on the evolution of the glass transition temperature.

Step-like features on caloric effects of graphenes
, 2014 We considered a graphene nano-ribbon with a longitudinal electric field (along $x$ direction) and a transversal magnetic field (along $z$ direction), and then observe (i) the electrocaloric effect ruled by an applied magnetic field and (ii) the ...
