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 ...
Elimination of fast variables in stochastic nonlinear kinetics
(2020-08-21)
A reduced chemical scheme involving a small number of variables is often sufficient to account for the deterministic evolution of the concentration of the main species contributing to a reaction. However, its predictions ...
Stochastic approach to Fisher and Kolmogorov, Petrovskii, and Piskunov wave fronts for species with different diffusivities in dilute and concentrated solutions
(2020-11-15)
A wave front of Fisher and Kolmogorov, Petrovskii, and Piskunov type involving two species A and B with different diffusion coefficients and is studied using a master equation approach in dilute and concentrated solutions. ...
Electrochemical sensor for selective tyramine determination, amplified by a molecularly imprinted polymer film
(Elsevier B.V., 2020-12-06)
A molecularly imprinted polymer (MIP) film based electrochemical sensor for selective determination of tyramine was devised, fabricated, and tested. Tyramine is generated in smoked and fermented food products. Therefore, ...
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 ...
Chemical and structural properties of reduced graphene oxide – dependence on the reducing agent
(Springer, 2020-11-09)
Graphene oxide (GO) prepared from graphite powder using a modified Hummers method and reduced graphene oxide (rGO) obtained from GO using different reductants, i.e. sodium borohydride, hydrazine, formaldehyde, sodium ...
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 ...
Characterization of charge transfer excited states in [2Fe–2S] iron–sulfur clusters using conventional configuration interaction techniques
(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, ...
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 ...
