Ion Complexation Explains Orders of Magnitude Changes in the Equilibrium Constant of Biochemical Reactions in Buffers Crowded by Nonionic Compounds
(ASC Publications, 2022-01-13)
The equilibrium constant (K) of biochemical complex formation in aqueous buffers with high concentration (>20 wt %) of nonionic compounds can vary by orders of magnitude in comparison with the K in a pure buffer. The precise ...
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 ...
Continuous non-equilibrium transition driven by the heat flow
(American Physical Society, 2021-08-02)
We discovered an out-of-equilibrium transition in the ideal gas between two walls, divided by an inner, adiabatic, movable wall. The system is driven out-of-equilibrium by supplying energy directly into the volume of the ...
Scaling equation for viscosity of polydimethylsiloxane in ethyl acetate: From dilute to concentrated solutions
(Elsevier, 2020)
Rheology of polymer solutions suffers from lack of universal model of viscosity applicable across wide range of concentrations. Here we build such a model on the basis of measured viscosity of polydimethylosiloxane (PDMS) ...
Macroscopic Viscosity of Polymer Solutions from the Nanoscale Analysis
(American Chemical Society, 2021)
The effective viscosity in polymer solutions probed by diffusion of nanoparticles depends on their size. It is a well-defined function of the probe size, the radius of gyration, mesh size (correlation length), activation ...
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. ...
Fluorescence correlation spectroscopy for multiple-site equilibrium binding: a case of doxorubicin–DNA interaction
(Royal Society of Chemistry, 2019)
Quantitative description of the interaction between doxorubicin (DOX), a broadly used anticancer drug,and DNA is the key to understand the action mechanism and side effects of its clinical use. However,the reported equilibrium ...
Thermodynamics of stationary states of the ideal gas in a heat flow
(AIP Publishing, 2022-11-01)
There is a long-standing question as to whether and to what extent it is possible to describe nonequilibrium systems in stationary states in terms of global thermodynamic functions. The positive answers have been obtained ...
Heteroaggregation of virions and microplastics reduces the number of active bacteriophages in aqueous environments
(Wiley, 2023-02-13)
The objective of this study is to explore the effects of microplastics on the viability of the bacteriophages in an aqueous environment. Bacteriophages (phages), i.e., viruses of bacteria, are essential in homeostasis. It ...
