Unusually Stable, Versatile, and Pure Arenediazonium Tosylates: Their Preparation, Structures, and Synthetic Applicability
Victor D. Filimonov,Marina E. Trusova,Pavel S. Postnikov,Elena A. Krasnokutskaya,Young Min Lee,Ho Yun Hwang,Hyunuk Kim,Ki-Whan Chi +7 more
TL;DR: A new, simple, and effective method for the diazotization of a wide range of arylamines has been developed by using a polymer-supported diazOTization agent in the presence of p-toluenesulfonic acid.
Journal ArticleDOI
Magnetic polyurethane sponge for efficient oil adsorption and separation of oil from oil-in-water emulsions
Olga Guselnikova,Alexandre Barras,Ahmed Addad,Elizaveta Sviridova,Sabine Szunerits,Pavel S. Postnikov,Rabah Boukherroub +6 more
TL;DR: In this paper, a magnetic polyurethane (MPU) sponge with super-hydrophobic/superoleophilic properties was fabricated in a two-step process consisting of surface functionalization of PU sponge with 3,5-bis(trifluoromethyl)benzenediazonium tosylate [ADT-(CF3)2] for the enhancement of its hydrophobicity, followed by incorporation of magnetic nanoparticles modified with the same diazoniium salt.
Journal ArticleDOI
Pretreatment-free selective and reproducible SERS-based detection of heavy metal ions on DTPA functionalized plasmonic platform
Olga Guselnikova,Olga Guselnikova,Pavel S. Postnikov,M. Erzina,Y. Kalachyova,Y. Kalachyova,Vaclav Svorcik,Oleksiy Lyutakov,Oleksiy Lyutakov +8 more
TL;DR: In this article, a surface plasmon-polariton based functionalized SERS platform for the detection of heavy metal ions was proposed, based on the homogeneous distribution of the plasm intensity on the ordered plasmor structure and high affinity of diethylenetriaminepentaacetic acid (DTPA) to heavy metal ion.
Journal ArticleDOI
Metal-organic framework (MOF-5) coated SERS active gold gratings: A platform for the selective detection of organic contaminants in soil
Olga Guselnikova,Olga Guselnikova,Pavel S. Postnikov,Pavel S. Postnikov,Roman Elashnikov,Elena Miliutina,Elena Miliutina,Vaclav Svorcik,Oleksiy Lyutakov,Oleksiy Lyutakov +9 more
TL;DR: The proposed SERS chip proved itself to be a perfect analytical probe for the detection of organophosphorus pesticides with high reliability and low detection limit up to 10-12 M, and selective detection and recognition of several relevant organic contaminants from the simulated soil was successfully demonstrated.
Journal ArticleDOI
Surface modification of Au and Ag plasmonic thin films via diazonium chemistry: Evaluation of structure and properties
Oleksiy Guselnikova,Oleksiy Guselnikova,Pavel S. Postnikov,Roman Elashnikov,Marina E. Trusova,Y. Kalachyova,Milan Libansky,Jiri Barek,Zdenka Kolska,Vaclav Svorcik,Oleksiy Lyutakov,Oleksiy Lyutakov +11 more
TL;DR: In this paper, the surface functionalization of plasmon-active Au and Ag films using arenediazonium tosylates was described, which was performed in the aqueous medium by the spontaneous and electrically induced mechanisms.
