Síntese de microfibras biopoliméricas de zeína/hidroxipropilmetilcelulose e nanofibrila para liberação controlada de fármacos
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência dos Materiais - PPGCM-SoCâmpus Sorocaba, 2022-09-09)
This master’s thesis aimed to develop electrospun microfibers formed by hydroxypropylcellulose acetate succinate (HPMC-AS), zein and celulose nanofibril to be used in the release of metronidazole (MDZ) and metronidazole ...
The impact of HPMC structure in the modulation of in vitro lipolysis: The role of bile salts
(Elsevier, 2017-01)
The behaviour of two hydroxypropylmethylcelluloses (HPMC), with different molecular structures: E5LV and E4M, has been analysed in the presence of the bile salts, both at the oil-water interface (emulsion behaviour, ...

Optimized and scaled-up production of cellulose-reinforced biodegradable composite films made up of carrot processing waste
(Elsevier B.V., 2018-10-01)
The ever-growing environmental concern arising from the unrestricted exploitation of fossil sources for the massive production of non-biodegradable materials encourages research on alternative renewable resources. We herein ...
Flexible random lasers in dye-doped bio-degradable cellulose nanocrystalline needles
(2020-01-01)
In this work, we developed and investigated a random laser based on rhodamine6G (Rh6G) in ethylene glycol (EG) solution with varying cellulose nanocrystalline (CNC) needles as scatterers in the lasing media. Besides the ...
Cationization of polysaccharides; a path to greener derivatives with many industrial applications
(Elsevier, 2014-01)
Cationic polysaccharides are widely used in diverse areas such as water treatment, papermaking, chemical, food, cosmetic, and petroleum industries. The combination of cationic polysaccharides with anionic polymers can lead ...
