Adsorption of Nitrophenols from Aqueous Media by N-Vinylpyrrolidone-Based Polymeric Adsorbents
Moscow University Chemistry Bulletin - Tập 74 - Trang 88-92 - 2019
P. T. Sukhanov, A. A. Kushnir
The adsorption of nitrophenols by N-vinylpyrrolidone-based polymeric adsorbents is studied under static conditions. The adsorption constants and energy characteristics are calculated. The adsorption mechanism and correlations between partition coefficients and adsorbate hydrophobicity are revealed. The contribution of hydrophobic and specific interactions to the adsorption mechanism is substantiat...... hiện toàn bộ
A new system for TNF-α quantification in human blood samples
Moscow University Chemistry Bulletin - Tập 63 - Trang 80-84 - 2008
T. V. Kuznetsova, B. I. Shevelev, Ya. S. Keruchen’ko, A. B. Shevelev
Full-length human TNF-α and its truncated derivative in which 18 N-terminal amino acid residues were replaced with T7-tag were obtained as inclusion bodies as a result of expression of artificial genes in E. coli cells. The purification and refolding procedures for the recombinant proteins were developed, and biological activity of the resultant proteins was demonstrated. Polyclonal antibodies aga...... hiện toàn bộ
Optimization of ionization conditions for analysis of humic substances from natural waters using Electrospray Ionization Fourier Transform Ion Cyclotron Resonance mass spectrometry (ESI FTICR MS)
Moscow University Chemistry Bulletin - - 2010
E. V. Kunenkov, Alexey Kononikhin, Irina V. Perminova, A. V. Garmash, Igor Popov, E. N. Nikolaev
Preparation of the recombinant НU-proteins from S. melliferum and M. gallisepticum and of their complexes with DS-DNA for structural NMR experiments
Moscow University Chemistry Bulletin - Tập 71 - Trang 221-226 - 2016
D. A. Altukhov, Y. K. Agapova, A. V. Vlaskina, D. A. Korzhenevskiy, A. Y. Nikolaeva, A. M. Frank-Kamenetskaya, E. V. Bocharov, T. V. Rakitina
We created a high-performance system for expression of 13C, 15N-double-labeled recombinant НU-proteins from mycoplasms S. melliferum (HUSpm) and M. gallisepticum (HUMgal), and a purification protocol that yields protein samples suitable for structure studies by high-resolution NMR. Using these proteins we optimized the conditions of NMR experiments and obtained two-dimensional heteronuclear 1H/15N...... hiện toàn bộ
Preparation of reagent indicator papers with silver triangular nanoplates for chemical analysis
Moscow University Chemistry Bulletin - Tập 72 - Trang 167-173 - 2017
V. V. Apyari, A. A. Furletov, A. V. Garshev, P. A. Volkov, M. O. Gorbunova, A. V. Shevchenko
An impregnation method to prepare reagent indicator papers with silver triangular nanoplates (TNPs) is developed. The conditions for obtaining modified papers (type of paper, method for applying TNPs, and drying conditions) allowing for an acceptably uniform distribution of the TNPs are chosen. The spectral characteristics of the prepared materials are studied. The presence of an intense TNP surfa...... hiện toàn bộ
Use of gold nanoparticles for immobilization of L-cysteine on TLC plates
Moscow University Chemistry Bulletin - Tập 64 - Trang 159-164 - 2009
E. N. Shapovalova, I. A. Ananieva, A. G. Majouga, N. V. Zik, O. A. Shpigun
A new method of immobilization of the chiral selector on the surface of TLC plates by means of stepwise impregnation by gold nanoparticles and L-cysteine is described. The novel silica- and alumina-based stationary phases for TLC demonstrate enantioselectivity toward tetrahydrozoline, hydroxyzine, ketoprofen, fenoprofen, pindolol, and fluoxetine. The influence of the composition of the mobile phas...... hiện toàn bộ
Ultrasound-assisted synthesis of nanostructured transition metal oxides
Moscow University Chemistry Bulletin - Tập 72 - Trang 42-48 - 2017
B. V. Romanovsky, A. A. Maerle, A. A. Karakulina, I. F. Moskovskaya
Ultrasound pretreatment of aqueous solutions of cetyltrimethylammonium bromide as a structure- directing agent has been applied to prepare nanostructured mesoporous Mn, Fe, and Ni oxides. After removal of the template by triple extraction with a water–ethanol solution of sodium acetate or ammonium chloride, air-calcined samples of oxide materials prepared in such a way possess surface areas of abo...... hiện toàn bộ
Sorption/photometric determination of 1-naphthylamine using polyurethane foams and 4-nitrophenyldiazonium tetrafluoroborate
Moscow University Chemistry Bulletin - Tập 62 - Trang 85-88 - 2007
E. V. Kuz’mina, L. N. Khatuntseva, V. V. Apyari, S. G. Dmitrienko
The sorption of 1-naphthylamine (NA) as 4-nitrobenzeneazonaphthylamine was studied as function of phase contact time, aqueous acidity, 4-nitrophenyldiazonium tetrafluoroborate (NPD) concentration, and NA concentration. A highly efficient method for the sorption/photometric determination of NA was developed.
