Comparison in mechanical properties of zirconium titanate (ZrTiO4) synthetized by alternative routes and sintered by microwave (MW)

Guillén Pineda, René Miguel; Borrell Tomás, María Amparo; Salvador Moya, Mª Dolores; Peñaranda Foix, Felipe Laureano; Moreno, R. (Editorial Universitat Politècnica de València, 2019-10-15)

[EN] At present, ZrTiO4 nanopowders are used as a dielectric in the electroceramic field, applications of catalysis, microwave telecommunications devices, pigments, composites, etc. One of the most interesting applications ...
Dense nanostructured zirconia compacts obtained by colloidal filtration of binary mixtures

Benavente Martínez, Rut; Salvador Moya, Mª Dolores; Alcázar, M.C.; Moreno, R. (Elsevier, 2012-04)

As starting materials two commercial nanosized zirconias doped with 3 mol% of Y 2O 3 were used: a powder of about 100 nm (TZ3YE, Tosoh, Japan) and a colloidal suspension of about 15 nm (Mel Chemicals, UK). Colloidal stability ...
Enhanced hydrothermal resistance of Y-TZP ceramics through colloidal processing

Rayón Encinas, Emilio; Moreno, R.; Alcazar, C.; Salvador Moya, Mª Dolores; Manjón Herrera, Francisco Javier; Jimenez-Pique, E.; Llanes, L. (Wiley, 2013-04)

Two commercial zirconia powders with 3mol% of yttria (TZ3YE and TZ3YS, labeled as ZE and ZS, respectively) supplied by Tosoh (Japan) were used for this study. Maximum colloidal stability for ZE was achieved by dispersing ...
Influence of the feedstock characteristics on the microstructure and properties of Al2O3 TiO2 plasma-sprayed coatings

Vicent, M.; Bannier, E.; Benavente Martínez, Rut; Salvador Moya, Mª Dolores; Molina, T.; Moreno, R.; Sánchez, E. (Elsevier Science SA, 2013-04-15)

[EN] Atmospheric plasma spraying (APS) is an interesting technique to obtain nanostructured coatings due to its versatility, simplicity and relatively low cost. However, nanometric powders cannot be fed into the plume using ...
Mechanical Harvesting of Citrus Fruits for Fresh Market with a Trunk Shaker and a Hand-Held Petrol Shaker

Torregrosa Mira, Antonio; Ortiz Sánchez, María Coral; Martin, B.; Moreno, R.; Molto, E.; Chueca, P. (International Society for Horticultural Science (ISHS), 2012)

Harvesting is one of the more expensive tasks in a Spanish citrus crop because it is done manually. Spanish researchers are investigating the possibilities of mechanical harvesting of citrus cultivated under Spanish ...
Microstructure and photocatalytic activity of APS coatings obtained from different TiO2 nanopowders

Bordes, M. C.; Vicent, M.; Moreno, A.; Moreno, R.; Borrell Tomás, María Amparo; Salvador Moya, Mª Dolores; Sanchez, E. (2013-04-15)

In recent years, intense research has shown that thermal spray techniques, especially atmospheric plasma spraying (APS), can be used to obtain nanostructured TiO2 coatings with effective photocatalytic activity. This study ...
Preparation and spray drying of Al2O3-TiO2 nanoparticle suspensions to obtain nanostructured coatings by APS

Sánchez, E.; Moreno, A.; Vicent, M.; Salvador Moya, Mª Dolores; Bonache Bezares, Victoria; Klyatskina ., Elizaveta; Santacruz, I.; Moreno, R. (Elsevier, 2010)

[EN] Al2O3-TiO2 coatings were deposited on austenitic stainless steel coupons from nanostructured powders by atmospheric plasma spraying (APS). Commercial suspensions of nanosized Al2O3 and TiO2 particles were used as ...
Properties of LZS/nanoAl2O3 glass-ceramic composites

Arcaro, S.; Moreno, B.; Chinarro, E.; Salvador Moya, Mª Dolores; Borrell Tomás, María Amparo; Nieto, M.I.; Moreno, R.; Novaes de Oliveira, A.P. (Elsevier, 2017-07-05)

[EN] The LZS glass-ceramic (19.58 Li2O center dot 11.10ZrO(2)center dot 69.32SiO(2)) have a high coefficient thermal expansion (CTE) which can be a limitation in some applications. The addition of alumina in a LZS glass-ceramic ...
Use of an Abscission Agent for Harvesting Mandarins in Spain

Moreno, R.; Chueca, P.; Garcera, C.; Intrigliolo Molina, Diego Sebastiano; Molto, E.; Torregrosa Mira, Antonio (International Society for Horticultural Science (ISHS), 2012)

Spain accounts for more than 55% of the European citrus production and is predominantly oriented towards fresh market. Harvesting accounts for more than 50% of production costs and methods of mass harvesting are under ...
