Published in 2017 at "Cell and Tissue Banking"

DOI: 10.1007/s10561-017-9625-6

Abstract: Demand for use of acellular allodermis is high but commercially appropriate products are not used routinely because of very high price and limited availability. These facts did motivate us to prepare acellular allodermis using a… read more here.

Published in 2017 at "Chemistry of Heterocyclic Compounds"

DOI: 10.1007/s10593-017-2116-7

Abstract: The reaction of 2-methyl-1-nitrоisothiourea with hydrazine in the presence of alkali metal bicarbonates (carbonates) resulted in the formation of 3,5-dinitrimino-1,2,4-triazole salts. The same salts were also formed by a reaction of 2-methyl-1-nitrоisothiourea with alkali metal… read more here.

Published in 2020 at "Russian Chemical Bulletin"

DOI: 10.1007/s11172-020-2740-8

Abstract: Long-chain alkylated 1,3-diphenyl-2-propanones are used in the synthesis of graphene nanostructures (graphene nanoribbons and quantum dots). A reliable procedure to obtain mono- or dialkylated diphenyl-2-propanones in 26 and 38% yields has been proposed. The method… read more here.

Published in 2021 at "Tetrahedron"

DOI: 10.1016/j.tet.2021.132189

Abstract: Abstract We describe a new reduction process for the efficient preparation of various, especially 2-substituted, piperidin-4-ones which are not accessible by other reaction pathways until now. Tetrahydropyridinylidene salts (THPS) with differing substitution pattern are the… read more here.

Published in 2017 at "Chemical communications"

DOI: 10.1039/c7cc01444a

Abstract: By using a facile calcination method, we succeeded in the preparation of partially spherical gold particles supported on TiO2 exhibiting photoabsorption due to surface plasmon resonance at around 620 nm. Surprisingly, the selective oxidation of… read more here.

Published in 2020 at "Cold Spring Harbor protocols"

DOI: 10.1101/pdb.prot101196

Abstract: This protocol differs from other transformation procedures in that the bacterial culture is grown at 18°C rather than the conventional 37°C. Otherwise, the protocol is unremarkable and follows a fairly standard course. Under standard laboratory… read more here.
