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 ...
Phosphorescence and Photophysical Parameters of Porphycene in Cryogenic Matrices
(MDPI, 2022-03-09)
Matrix isolation studies were carried out for porphycene, an isomer of porphyrin, embedded
in solid nitrogen and xenon. The external heavy atom effect resulted in nearly a 100% population
of the triplet state and in the ...
You will know by its tail: a method for quantification of heterogeneity of bacterial populations using single-cell MIC profiling
(Royal Society of Chemistry, 2022-10-05)
Severe non-healing infections are often caused by multiple pathogens or by genetic variants of the same pathogen exhibiting different levels of antibiotic resistance. For example, polymicrobial diabetic foot infections ...
Searching for correlations between geometric and spectroscopic parameters of intramolecular hydrogen bonds in porphyrin-like macrocycles
(Royal Society of Chemistry, 2022-09-11)
Chemical bond lengths and angles are characteristic structural parameters of a molecule. Similarly, the frequencies of the vibrational modes and the NMR chemical shifts are unique “chemical fingerprints” specific to a ...
Revealing the Variation of Photodetectivity in MAPbI3 and MAPb(I0.88Br0.12)3 Single Crystal Based Photodetectors Under Electrical Poling-Induced Polarization
(ACS Publications, 2022-07-28)
The use of electrical poling to induce polarization
potential has been found to increase the photocurrent (Ilight) in
hybrid perovskite-based devices; however, the origin of this process
has not been fully understood. ...
Amyloid β interaction with model cell membranes – What are the toxicity-defining properties of amyloid β?
(Elsevier B.V., 2022-01-21)
Disruption of the neuronal membrane by toxic amyloid β oligomers is hypothesized to be the major event associated with Alzheimer's disease's neurotoxicity. Misfolding of amyloid β is followed by aggregation via different ...
A microfluidic system for analysis of electrochemical processing using a highly sensitive optical fiber microcavity
(Elsevier, 2022)
Microfluidics provide unique possibilities to control tiny volumes of liquids and their composition. In this work we combined a microfluidic system with a microcavity in-line Mach-Zehnder interferometer (μIMZI) induced in ...
Simulation and analysis of the relaxation dynamics of a photochromic furylfulgide
(Royal Society of Chemistry, 2022-05-15)
Furylfulgides, a class of photochromic organic compounds, show a complex system of photoinduced
reactions. In the present study, the excited-state dynamics of the E α and E β isomers of a
representative furylfulgide is ...
A new look at molecular and electronic structure of homoleptic diiron(II,II) complexes with N,N-bidentate ligands: Combined experimental and theoretical study
(Wiley, 2022)
Paddlewheel-type dinuclear complexes featuring metal–metal bonding have been the subject of widespread interest due to fundamental interest in their electronic structures and potential applications. Here, we explore the ...
