ZNFE2 O4 @MNFE2 O4 MAGNETIC NANOPARTICLES AS A PROMISING CARRIER FOR LIPASE IMMOBILIZATION
X Международная конференция молодых ученых: биоинформатиков, биотехнологов, биофизиков, вирусологов и молекулярных биологов — 2023: Cб. тез., 2023In the field of development of highly efficient biocatalysts, more modern methods of their production are required, for example, the selection of new carriers for enzymes. The carrier can provide resistance to various effects on the biomolecule or change the conditions of the reaction.

Potential energy surface of triplet O4
The Journal of Chemical Physics, 2018We present a global ground-state potential energy surface (PES) for the triplet spin state of O4 that is suitable for treating high-energy vibrational–rotational energy transfer and collision-induced dissociation in electronically adiabatic spin-conserving O2–O2 collisions.

Specific heat of low doped magnetite, Fe3−Ti O4 and Fe3−Zn O4
Journal of Magnetism and Magnetic Materials, 1995Abstract Systematic studies of specific heat and entropy of the Verwey transition in Fe3−xTixO4 and Fe3−yZnyO4 series are reported. The results of these investigations demonstrate that in Fe3−xTixO4 and Fe3−yZnyO4 systems exists only one, well defined phase transition.

Na3Co2(As0.52P0.48)O4(As0.95P0.05)2O7
2013Le composé du titre, le dicobalt(II) trisodique (arséniate/phosphate) (diarséniate/diphosphate), a été préparé par une réaction à l'état solide. Il est isostructural avec Na3Co2AsO4As2O7. Le cadre montre la présence d'unités CoX22O12 (X2 est statistiquement désordonné avec As0.95P0.05) formées en partageant les coins entre les groupes octaèdres Co1O6 ...

O4-Methyl-, O4-ethyl-, and O4-isopropylthymidine 5'-triphosphates, which can be formed by N-nitroso carcinogens, were tested for their ability to substitute for thymidine 5'-triphosphate (dTTP) in synthesis catalyzed by Escherichia coli DNA polymerase I (Pol I) by using activated DNA or synthetic polymers as templates. All could substitute for dTTP for

Proton positions in spinel H0.9Li0.1[Li0.33Ti1.67]O4, an ion-exchanged spinel Li1[Li0.33Ti1.67]O4
Physica B: Condensed Matter, 2004Abstract Spinel Li1[Li0.33Ti1.67]O4 is an attractive candidate for the use as anode material in Li-ion batteries. This work focusses on the structural changes of spinel Li1[Li0.33Ti1.67]O4 upon the exchange of Li-ions with protons leading to the composition H0.9Li0.1[Li0.33Ti1.67]O4.

Cell proliferation during successive stages of oligodendrocyte development was delineated in the rat brain and optic nerve. Surface antigens, A2B5, O4, and galactocerebroside (GalC) identified three cell populations emerging in sequence; the incorporation of bromodeoxyuridine into newly synthesized DNA identified the proliferative cells.
