Bioacetylation of seaweed alginate [PDF]

Applied and Environmental Microbiology, 1995
Seaweed alginate was acetylated by intact, resting cells of Pseudomonas syringae ATCC 19304. Maximum acetylation of this polymer occurred at a pH of 6.0 and a temperature of 25 deg C. Aeration and gluconic acid were required for an optimal reaction. A reactor which contained carbon-immobilized cells was constructed to continuously acetylate alginate ...

Magnetization Enhancement in Magnetite Nanoparticles Capped with Alginic Acid [PDF]

Composites Part B, 64 (2014) 147, 2013
We report on the effect of organic acid capping on the behavior of magnetite nanoparticles. The nanoparticles of magnetite were obtained using microwave activated process, and the magnetic properties as well as the electron magnetic resonance behavior were studied for the Fe3O4 nanoparticles capped with alginic acid.

The Role of the Mucus Barrier in Digestion [PDF]

, 2012
Mucus forms a protective layer across a variety of epithelial surfaces. In the gastrointestinal (GI) tract, the barrier has to permit the uptake of nutrients, while excluding potential hazards, such as pathogenic bacteria.

Resistência mecânica de hidrogéis termo-sensíveis constituídos de Alginato-Ca2+ / PNIPAAm, tipo Semi-IPN Mechanicals resistance of thermosensitive hydrogels consisting of alginate-Ca2+ / PNIPAAm, type Semi-IPN

Química Nova, 2007
Thermosensitive hydrogels were synthesized using alginate-Ca2+ in association with a thermosensitive polymer, such as PNIPAAm. The mechanical properties of the hydrogels were determined measuring the maximum tension of deformation.

Effective approach for taking into account interactions of quasiparticles from the low-temperature behavior of a deformed fermion-gas model [PDF]

Journal of Statistical Mechanics: Theory and Experiment (2017) 043105, 2017
A deformed fermion gas model aimed at taking into account thermal and electronic properties of quasiparticle systems is devised. The model is constructed by the fermionic Fibonacci oscillators whose spectrum is given by a generalized Fibonacci sequence. We first introduce some new properties concerning the Fibonacci calculus.
