Characterization of silica–water nanofluids dispersed with an ultrasound probe: A study of their physical properties and stability
Elsevier (2012)The stability and agglomeration state of nanofluids are key parameters for their use in different applications. Silica nanofluids were prepared by dispersing the nanoparticles in distilled water using an ultrasonic probe, ... -
Dispersion requirements in coherent frequency-to-time mapping
Optical Society of America (2011)The frequency-to-time mapping technique (also known as the temporal far-field phenomenon) usually requires a significant amount of dispersion to stretch an ultrashort optical pulse so that the intensity profile becomes ... -
Dispersion of TiO2nanopowders to obtain homogeneous nanostructured granules by spray-drying
Elsevier (2011)This work deals with the dispersion and stabilisation of nanosized TiO2 particles in an aqueous medium as a first step in the preparation of spray-dried nanostructured powders. A colloidal route leading to the production ... -
Study of the dispersion of nanoclays in a LDPE matrix using microscopy and in-process ultrasonic monitoring
Elsevier (2009)LDPE/montmorillonite and LDPE/kaolinite compounds were prepared by twin-screw extrusion using two screw profiles. The microstructure of the samples was determined by a combination of techniques: wide angle X-ray scattering ... -
Ultrashort pulse fiber delivery with optimized dispersion control by reflection grisms at 800 nm
Optical Society of America (2012)We experimentally demonstrate a compact and efficient arrangement for fiber delivery of sub-30 fs energetic light pulses at 800 nm. Pulses coming from a broadband Ti:Sapphire oscillator are negatively pre-chirped by a ...
