Innovative uses of carbamoyl benzoic acids in coagulation-flocculation’s processes of wastewater
(2017-01)
The use of carbamoyl benzoic, acids as separation new agents, to remove on the hazardous heavy metals,
that are frequently, contained in metal plating wastewater is reported in this paper. The interaction of
ionic heavy ...
Modification of chitosan with carbamoyl benzoic acids for testing its coagulant-flocculant and binding capacities in removal of metallic ions typically contained in plating wastewater
(2017-09-08)
This paper proposes the use chitosan modified with carbamoyl benzoic acids as new coagulant-flocculant agents for metals removal from aqueous solutions. The grafted chitosan species as chitosan dianhydride (ChD) and chitosan ...
Photoredox-mediated aminoalkylation and carbamoylation of azomethine imines
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Química - PPGQCâmpus São Carlos, 2021-08-25)
Over the past decade, the organic synthetic community has witnessed the emergence of a new and complementary approach to the conventional radical chemistry. Photochemistry has proven to be a powerful and more sustainable ...
Structural analysis of a novel N-carbamoyl-D-amino acid amidohydrolase from a Brazilian Bradyrhizobium japonicum strain: In silico insights by molecular modelling, docking and molecular dynamics
(2019-01-01)
In this work we performed several in silico analyses to describe the relevant structural aspects of an enzyme N-Carbamoyl-D-amino acid amidohydrolase (D-NCAase) encoded on the genome of the Brazilian strain CPAC 15 (=SEMIA ...
Imobilização e estabilização de D-Hidantoinase para a produção de N-Carbamoil-D-Fenilglicina
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Biotecnologia - PPGBiotec, 2008-09-29)
Immobilization and stabilization of enzymes increases their potential for use in industrial scale. D-hydantoinases (dihidropirimidina amidrohidrolase EC 3.5.2.2) catalyze the hydrolysis of D-hydantoins, generating the ...
Síntese de derivados de asparaginas não-naturais N4-substituídas e modificação de peptídeos: adição fotoredox de radicais carbamoil à dehidroalanina
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Química - PPGQCâmpus São Carlos, 2021-08-27)
The development of sustainable methodologies for the synthesis of byologic relevant molecules is of great importance for both, academia (especially in organic synthesis and medicinal chemistry) and pharmaceutical industry. ...
Method for the synthesis of N-alkyl-O-alkyl carbamates
(Royal Society of Chemistry, 2014-02)
Primary and secondary carbamates were prepared from primary, secondary and neo-pentyl alcohols, and carbonyl-di-imidazole (CDI), using a new three step method. Non-acidic alcohols reacted with CDI affording carbamoyl-imidazoles ...
Eco‐friendly magnetic nanoscavengers as emerging materials for improving reclaimed water quality
(2020-12)
Magnetic nanoparticles are synthesized and modified during a chemical co‐precipitation to produce three different magnetic nanoscavengers: nanomagnetite‐chitosan, nanomagnetite‐nanodiamond and nanomagnetite‐chitosan grafted ...
