Electrospun polycarbonate/boehmite fibers as support structures for inclusion of boehmite nanoparticles in an epoxy matrix

2022
Die Entwicklung und Verbesserung von faserverstärkten Polymerverbundwerkstoffen (FRC) war in den letzten Jahren Gegenstand zahlreicher Studien. Sektoren wie die Luft- und Raumfahrt, die Schifffahrt, die Automobilindustrie, der Hoch- und Tiefbau und andere suchen konstant nach Technologien, die die Herstellung von leichten Verbundwerkstoffen mit hoher ...

Adsorption of α-Alanine on Boehmite

Journal of Colloid and Interface Science, 1997
The adsorption of alpha-alanine on boehmite is effected at room temperature in aqueous solutions at different pH values (2.5, 6.0, 12.2). The different forms of alpha-alanine prevalent in the different media result in different modes of adsorption, different uptakes that generally increase with pH, and different responses of the pore structure of ...

Polypropylene + boehmite nanocomposite fibers

Journal of Polymer Engineering, 2012
Abstract The influence of nanosized filler particles on mechanical properties of composite fibers has some specific features related to the fiber matrix, its preparation and the filler content, as well as the orientation of the fibers at their drawing.

Thermal Decomposition Kinetics of Boehmite

Journal of the American Ceramic Society, 1966
The decomposition of boehmite, or alpha alumina monohydrate, was studied in water vapor and nitrogen atmospheres between 430° and 500°C. Powder samples used consisted of agglomerates of very small boehmite crystallites. The rate of decomposition was determined with a transducer which measured the loss of sample weight due to the ...

Structure Refinement of Deuterated Boehmite

Clays and Clay Minerals, 1985
Abstract The crystal structure of a deuterated synthetic boehmite powder, γ -AIOOD, has been determined by time-of-flight neutron diffraction and Rietveld profile refinement in space group Cmcm to a weighted profile R of 3.71%.

About boehmite and beyond

1997
The distribution of cationic vacancies in transition aluminas obtained by dehydration of boehmite has been investigated using HRTEM combined with an image simulation technique. Interstitial vacancies in a cubic-packed oxygen network have been found to be concentrated in an orderly fashion on low indexed lattice planes like the {110} and {100} planes of

Role of boehmite/solution interface in boehmite precipitation from supersaturated sodium aluminate solutions

Hydrometallurgy, 2004
This work presents the developments made in the Laboratory of Metallurgy of the National Technical University of Athens in the field of boehmite precipitation from supersaturated sodium aluminate solutions under atmospheric conditions. Initially, the boehmite process is described by giving emphasis to kinetic problems that reduce the process efficiency
