Journal ArticleDOI
Direct coagulation casting of nano-8YSZ powder suspensions using nano-MgO as coagulating agent
TL;DR: In this paper, a high solid content aqueous suspension from nano-8YSZ (15-50nm) using a suitable PAA-NH 4 dispersant was obtained, and the nanosuspension was then successfully cast into a nonporous PVC mold at 25°C producing a dense structure without cracks after 6h.
Journal ArticleDOI
Plasma-modified TiO2/polyetherimide nanocomposite fibers for photocatalytic degradation of organic compounds
Sarah Mozzaquatro Pasini,Alexsandra Valério,Selene M.A. Guelli U. de Souza,Dachamir Hotza,Guilin Yin,Jingfeng Wang,Antônio Augusto Ulson de Souza +6 more
TL;DR: In this article, submicrometric polyetherimide (PEI) fibers were electrospun with incorporated TiO2 nanoparticles, and the fibers were submitted to cold plasma in air and nitrogen atmospheres to enhance adhesion and photocatalytic performance.
Journal ArticleDOI
Premix membrane emulsification using flat microfiltration inorganic membranes with tailored structure and composition
Rafael Kenji Nishihora,Rafael Kenji Nishihora,Laura Luhede,Udo Fritsching,Mara Gabriela Novy Quadri,Dachamir Hotza,Kurosch Rezwan,Michaela Wilhelm +7 more
TL;DR: In this paper, a uniform oil-in-water emulsions were prepared using MCT (medium-chain fatty acid triglyceride, 10 ¼ ) as the oily dispersed phase and polysorbate 80 as the surfactant.
Journal ArticleDOI
Roll Pressed LZSA Glass-Ceramics
G. M. Reitz,Oscar Rubem Klegues Montedo,Orestes Estevam Alarcon,Dachamir Hotza,A.P. Novaes de Oliveira +4 more
TL;DR: In this article, the authors reported some experimental results regarding to a Li2O-ZrO2-SiO2Al2O3 (LZSA) sintered glass-ceramic material obtained by roll pressing of glass powders with an added (7 wt.%) inorganic material (bentonite) as binder.
Journal ArticleDOI
Characterization of pulp and paper mill waste for the production of waste-based cement
Lisandro Simão,Dachamir Hotza,Fabiano Raupp-Pereira,João A. Labrincha,Oscar Rubem Klegues Montedo +4 more
TL;DR: In this paper, the results of a study that characterized pulp and paper mill waste and their recycling in clinker production were presented, and the clinker was characterized, milled, and mixed with calcium sulphate for use as an ecocement.
