Multimode Vibrational Strong Coupling of Methyl Salicylate to a Fabry−Pérot Microcavity
(American Chemical Society, 2020)The strong coupling of an IR-active molecular transition with an optical mode of the cavity results in vibrational polaritons, which opens a new way to control chemical reactivity via confined electromagnetic fields of the ... -
Confinement of Colloids with Competing Interactions in Ordered Porous Materials
(American Chemical Society, 2020)In this work, we explore the possibility of promoting the formation of ordered microphases by confinement of colloids with competing interactions in ordered porous materials. For that aim, we consider three families of ... -
The influence of confinement on the structure of colloidal systems with competing interactions
(Royal Society of Chemistry, 2020)Colloidal systems with competing interactions have a complex phase diagram with several periodic microphases, in which particles are arranged in lamellae, cylinders or clusters. Using grand canonical Monte Carlo simulations, ... -
Shape Transformations of Vesicles Induced by Their Adhesion to Flat Surfaces
(American Chemical Society, 2020)The shape transformations of lipid vesicles induced by the adhesion to a flat surface is investigated. We perform the calculations within the framework of the Helfrich spontaneous curvature model. The calculations were ... -
Interpretation of Resistance, Capacitance, Defect Density, and Activation Energy Levels in Single-Crystalline MAPbI3
(American Chemical Society, 2020)Hybrid inorganic–organic lead halide perovskites have attracted a significant research interest in the last 10 years due to their broad-area applications in optoelectronic devices such as solar cells, lasers, photodetectors, ... -
Elucidation of the role of guanidinium incorporation in single-crystalline MAPbI3 perovskite on ion migration and activation energy
(Royal Society of Chemistry, 2020)Ion migration plays a significant role in the overall stability and power conversion efficiency of perovskite solar cells (PSCs). This process was found to be influenced by the compositional engineering of the A-site cation ... -
Correlation between adhesion strength and phase behaviour in solid-supported lipid membranes
(Elsevier, 2020)Fundamental understanding of vesicle adhesion in the size range ≤ 200 nm is of major importance when addressing biologically relevant processes involving the presence of small vesicles like exosomes or endosomes. Using ... -
Chitosan-Based N‑Doped Carbon Materials for Electrocatalytic and Photocatalytic Applications
(American Chemical Society, 2020)Chitosan-derived N-doped carbon materials are attractive candidates for the preparation of catalysts with a wide range of applications. Chitosan is a nitrogen rich (∼7 wt %) renewable biomass resource derived from seafood ... -
Single-molecule brightness analysis for the determination of anticancer drug interactions with DNA
(Royal Society of Chemistry, 2020)Anthracyclines are one of the most studied anticancer drugs approved for medical treatment. The equilibrium constant (K) of the reaction between these drugs with DNA in both in vitro and in vivo experiments lacks consensus. ... -
How Does a Simple Network of Chemical Oscillators See the Japanese Flag?
(Frontiers Media SA, 2020)Chemical computing is something we use every day (e.g., in the brain), but we can still not explore and master its potential in human-made experiments. It is expected that the maximum computational efficiency of a chemical ... -
Can A Network of Chemical Oscillators Help to Diagnose Schizophrenia?
(Old City Publishing, Inc., 2020)Schizophrenia is one of the most common mental disorders, however it is difficult to detect and can remain undiagnosed for years. It is believed that information if a patient is ill can be extracted from EEG signals recorded ... -
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 ... -
Gravity-driven microfluidic assay for digital enumeration of bacteria and for antibiotic susceptibility testing
(Royal Society of Chemistry, 2020-01-07)The alarming dynamics of antibiotic-resistant infections calls for the development of rapid and point-of-care (POC) antibiotic susceptibility testing (AST) methods. Here, we demonstrated the first completely stand-alone ... -
Physicochemical Properties of Terebic Acid, MBTCA, Diaterpenylic Acid Acetate, and Pinanediol as Relevant α‑Pinene Oxidation Products
(American Chemical Society, 2020-03)The physicochemical properties and the synthesis of four α-pinene oxidation products, terebic acid, 3-methyl-1,2,3-butanetricarboxylic acid (MBTCA), diaterpenylic acid acetate (DTAA), and pinanediol, are presented in this ... -
Nanomechanical characterization of single phospholipid bilayer in ripple phase with PF-QNM AFM
(Elsevier B.V., 2020-05-07)Topography and nanomechanical properties of the supported 1,2-dimyristoyl-sn-glycero-3-phosphocholine (DMPC) single bilayer in the ripple phase were investigated by atomic force microscopy with the use of PeakForce ... -

(Springer, 2020-06-22)The experimental UV–Vis spectra of the biologically relevant [2Fe–2S] iron–sulfur clusters feature typically three bands in the 300–800 nm range. Based on ground-state orbitals and using the one electron transition picture, ... -
Alzheimer's disease-related amyloid β peptide causes structural disordering of lipids and changes the electric properties of a floating bilayer lipid membrane
(Royal Society of Chemistry, 2020-06-27)Neurodegeneration in Alzheimer's disease is associated with disruption of the neuronal cell membrane by the amyloid β (Aβ) peptide. However, the disruption mechanism and the resulting changes in membrane properties remain ... -
Elimination of fast variables in stochastic nonlinear kinetics
