Thermodynamic and kinetic effects in the crystallization of metal–organic frameworks
Published 2018“…Recently, however, this simple relationship has had to be reconsidered with the emergence of some very flexible structures wherein the open structures are more stable than their denser analogues at finite temperatures because of their large vibrational entropies. In the final section we describe how the concepts developed in the MOF work have been extended into the closely related area of hybrid organic–inorganic perovskites. …”

Tissue scale electrophysiological-mechanical continuum modelling for white matter transcranial ultrasound neuromodulation
Published 2022“…Whether or not this hypothesis is fully accurate microscopically in the context of TUS, it offers a phenomenological framework that could be used at the organ scale to quantify electrical induction in the presence of minute mechanical vibrations. However, the flexoelectric theory relies on formulations directly built on the microstructural description of the underlying dielectric polarisation. …”

Novel functionalized polythiophene-coated Fe3O4 nanoparticles for magnetic solid-phase extraction of phthalates
Published 2016“…The nanocomposites were characterized by Fourier transform infra-red (FTIR), X-ray diffractometry (XRD), Brunauer-Emmett-Teller (BET) surface area analysis, analyzer transmission electron microscopy (TEM) and vibrating sample magnetometry (VSM). P3TArH-coated MNPs (MNP@P3TArH) showed higher capabilities for the extraction of commonly-used phthalates and were optimized for the magnetic-solid phase extraction (MSPE) of environmental samples. …”
