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 ... -
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 ... -
Model of an Artificial Blastula for Assessing Development Toxicity
(Intechopen, 2023-03-04)We are concerned with computer simulations of a ring of 20 coupled CSTRs with glycolytic oscillatory reaction. Each CSTR represents an artificial cell, and the ring can be regarded as an artificial blastula. The cells ... -
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 ... -
Droplet microfluidics for high-throughput analysis of antibiotic susceptibility in bacterial cells and populations
(American Chemical Society, 2022-02-04)Antibiotic-resistant bacteria are an increasing concern both in everyday life and specialized environments such as healthcare. As the rate of antibiotic-resistant infections rises, so do complications to health and the ... -
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. ... -
Atomic Layer Engineering of Aluminum-Doped Zinc Oxide Films for Efficient and Stable Perovskite Solar Cells
(Wiley, 2022-05-22)Atomic layer deposition (ALD) has been considered as an efficient method to deposit high quality and uniform thin films of various electron transport materials for perovskite solar cells (PSCs). Here, the effect of ... -
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 ... -
