Determination of psychotic behaviour using a network of chemical oscillators
(International Frequency Sensor Association (IFSA) Publishing, S. L., 2020)Schizophrenia is the most common form of psychotic behaviour where patients experiences hallucination, dillusion or chaotic speech. Schizophrenia is difficult to detect and easily go undetected for years. Here we propose the ... -

Effect of proximity to ionic liquid-solvent demixing on electrical double layers
(Journal of Molecular Liquids, 2019-11)There is a growing interest in the properties of ionic liquids (ILs) and IL-solvent mixtures at metallic interfaces, particularly due to their applications in energy storage. The main focus so far has been on electrical ... -
Effective screening of Coulomb repulsions in water accelerates reactions of like-charged compounds by orders of magnitude
(Springer Nature, 2022-10-28)The reaction kinetics between like-charged compounds in water is extremely slow due to Coulomb repulsions. Here, we demonstrate that by screening these interactions and, in consequence, increasing the local concentration ... -
Electrical Double Layers Close to Ionic Liquid–Solvent Demixing
(American Chemical Society, 2018-12-31)Electrical double layers (EDLs) play a key role in energy storage and have been suggested to have applications in energy generation. Recently, there has been an expansion of interest in EDLs, but EDLs with ionic liquid–solvent ... -
