Production of bacterial cellulose nanocrystals via enzymatic hydrolysis and eva...
Soeiro, Victória S.; Tundisi, Louise L.; Novaes, Letícia C. L.; Mazzola, Priscila G.; Aranha, Norberto; Grotto, Denise; Júnior, José M. O.This study aimed to obtain the bacterial cellulose nanocrystals (CNC) by enzymatic hydrolysis and verify the CNC application as coating material in alginate particles. Therefore, the production of CNC was carried out through two enzymatic hydrolysis methods involving a time period of 48 and 72 h. 0.35 mg of dry mass of cellulose was produced approximately 1.6 × 1011 CNC/mL. The CNC obtained by enzymatic hydroly...
Organosulphur-modified biochar: An effective green adsorbent for removing metal...
Alves Macedo, João Carlos [UNESP]; Sartori Jeunon Gontijo, Erik [UNESP]; Gómez Herrera, Santiago [UNESP]; Rangel, Elidiane Cipriano [UNESP]Made available in DSpace on 2021-06-25T11:08:28Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-02-01; Organosulphur-modified biochar (BC) can be used as a green adsorbent for removing potentially toxic metal ions from aqueous solutions. In this study, sugarcane bagasse BCs (produced at pyrolysis temperatures from 300 to 700°C) were modified in a single-step reaction with isothiocyanate. The performance ...
Structural comparison, physicochemical properties, and in vitro release profile...
Souza, Juliana Ferreira de; Pontes, Katiusca da Silva; Alves, Thais Francine Ribeiro; Barros, Cecilia Torqueti de; Amaral, Venancio AlvesLyotropic liquid crystal (LLC) is a nano-biomimetic lipid-based system, which has thermodynamic property that is peculiar to it, and suitable for its structural ordering, which facilitates more intimate contact with the tissues. The LLC as a carrier of curcumin has been much studied, however, this is the first time that hydrotrope method approach has been used in the lamellar system precursor of the LLC nanopar...
Nanocompósitos de polietileno linear de baixa densidade (LLDPE)/argila montmori...
Komatsu, DanielUniversidade Federal de Sao Carlos; Polymer nanocomposites filled with lamellar silicates are considered hybrid materials (organic-inorganic) of great interest both in industry and the universities, since their properties are superior to neat polymer. In this work LLDPE/ montmorillonite clay (Cloisite 20A) nanocomposites were prepared by diluting a masterbatch (20%w/w) clay, on a twin-screw extruder to get fina...
