The interaction between metal nanoparticles and bacteria belongs to the central issues in a dynamically growing bionanotechnological research. Herein, we investigated adhesion efficiency of gold (30 nm) for various bacterial strains, both Gram-positive (Bacillus subtilis, Staphylococcus carnosus) Gram-negative (Neisseria subflava, Stenotrophomonas maltophilia). thorough microscopic (SEM/TEM) observations revealed that do not penetrate into cells but adhere walls. Large differences adhered...
Manganese, iron, and cobalt model spinel catalysts were systematically investigated for understanding the roots of their divergent performance in N2O decomposition. The characterized by XRD, RS, N2-BET, SEM, STEM/EELS techniques before after reaction. Their redox properties thermodynamic stability range thoroughly examined survey narrow scan TPR/TPO cycles. results accounted constructed size-dependent Ellingham diagrams. It was shown that Fe3O4 Mn3O4 spinels exhibit redox-labile Mn2+/Mn3+...
Abstract The SOLARIS synchrotron located in Krakow, Poland, is a third-generation light source operating at medium electron energy. first was observed 2015, and the consequent development of infrastructure lead to users’ experiments soft X-ray energies 2018. Presently, expands its operation towards hard X-rays with continuous developments beamlines concurrent infrastructure. In following, we will summarize design, describe research together main performance parameters, upgrade, plans.
tRNA modifications affect ribosomal elongation speed and co-translational folding dynamics. The Elongator complex is responsible for introducing 5-carboxymethyl at wobble uridine bases (cm
Plane wave periodic GGA-PBE+U density functional theory calculations were used to study the structure, surface energy, and equilibrium shape of faceted nanocrystals for a series cubic (Fd3m) 2–3 AB2O4 spinels with following formula: Co[Co2]O4, Mg[Co2]O4, Zn[Co2]O4, Co[NiCo]O4, Co[MnCo]O4, Fe[FeCo]O4, Co[Al2]O4. Their bulk geometries (lattice constants oxygen u parameters) as well electronic magnetic properties computed compared experimental data. All planes, (100), (110), (111), exposed by...
Periodic spin unrestricted, gradient corrected DFT calculations joined with atomistic thermodynamic modeling and experiment were used to study the structure stability of various reactive oxygen species (ROS) vacancies produced on most stable terminations cobalt spinel (100) surface. The surface state diagram in a wide range pressures temperatures was constructed for coverage varying from ΘO = 1.51 atom·nm–2 6.04 atom·nm–2. A large variety unraveled ROS includes diatomic superoxo...
Plants use solar energy to power cellular metabolism. The oxidation of plastoquinol and reduction plastocyanin by cytochrome b6f (Cyt b6f) is known as one the key steps photosynthesis, but catalytic mechanism in plastoquinone site (Qp) remains elusive. Here, we describe two high-resolution cryo-EM structures spinach Cyt homodimer with endogenous plastoquinones complex plastocyanin. Three are visible line up after another head tail near Qp both monomers, indicating existence a channel each...
Utilization of visible light by photosensitization semiconductor photocatalysts via surface attachment small colorless organic pollutants (COP) is an effective way to stimulate their photocatalytic degradation. Herein, means the spectroscopic, photoelectrochemical, spectroelectrochemical, and studies combined with DFT+D molecular modeling, we show how disubstituted benzene derivatives, like catechol (CAT), salicylic acid (SAL), phthalic (PTA), terephthalic (TPA), can tune properties rutile...
Pseudouridine (Ψ), the isomer of uridine, is ubiquitously found in RNA, including tRNA, rRNA, and mRNA. Human pseudouridine synthase 3 (PUS3) catalyzes pseudouridylation position 38/39 tRNAs. However, molecular mechanisms by which it recognizes its RNA targets achieves site specificity remain elusive. Here, we determine single-particle cryo-EM structures PUS3 apo form bound to three tRNAs, showing how symmetric homodimer tRNAs positions target uridine next active site. Structure-guided...
Polycrystalline zirconium titanate, ZrTiO4, has been prepared via sol–gel chemistry and its properties both as a semiconducting oxide photoactive system have investigated by experimental computational techniques. The exhibits structure analogous to those of the main TiO2 polymorphs with slightly higher band gap 3.65 eV. Theoretical results explain this small difference in terms composition lower part conduction band, which is based on Ti 3d orbitals. Interestingly titanate much less...
