Laser process for coating adhesion/curing
FSP technology (Flame Spray Pirolisis)
Lurederra has developed an own technology to manufacture totally synthetic nanoparticles, which permits to obtain the morphology and size desired thereby achieving an adjustment and control of their chemical activity, specificity and selectivity, allowing to produce different types of nanoparticles for such varied uses as polishes lenses, catalysts and photovoltaic cells, among others.
The great versatility of the FSP technology (Flame Spray Pirolisis) developed by Lurederra allows to produce nanoparticles of ceramic and metallic oxides (simple and multicomponent) of more than 60 elements of the Periodic Table as well as nanoparticles of noble metals.
For that, it counts with 4 nanoparticles production lines of own design and with a joint production capacity of around 13 Tn per year of highly sophisticated nanoparticles.
Lurederra is currently able to provide specific nanoproducts developed customized for specific industrial applications of its customers.Within the possibilities they are include, for example, nonstick and anticorrosion coatings for metals, coatings that provide properties of high water and oil repellency to substrates as diverse as construction materials, textiles, paper and plastics or heat barrier properties for crystals. In short, Lurederra is able to introduce CELABOR Assisted impregnation (A.I.) for the inclusion of ZnO Pressurized Hot Liquid Extraction (PHLE) nanotexturization effects in almost any substrate by first converting a small area in a large surface to then endowed it with the effect desired. And all thanks to nanotechnology.
Assisted impregnation (A.I.) for the inclusion of ZnO
NCSRD group will employ a novel dendrimer templating strategy called assisted impregnation (A.I.) for the inclusion of ZnO into mesoporous hosts. Dendritic polymers owing to their highly branched tree-like architecture and multi-functionality are uniquely suited hosts or stabilizers for the production of ultrasmall nanoparticles with controlled size. In this project, the chemical and chelating properties of water soluble, low cost and readily available hyperbranched polymers will be exploited for the synthesis of monodispersed metal oxide nanoparticles. The employed polymers include hyperbranched polyethyleneimine (PEI) and carboxy- methylated polyethyleneimine (Trilon-P) bearing different functional end groups.
By immobilizing metal species in fixed positions through metal- ligand complex formation, effective control over final metal particle size and dispersion state will be attained (Figure 2). Besides, delivering small-sized uniformly dispersed NPs and hence promoting their original antibacterial action, the proposed method offers additional advantages related to the reduction of ZnO amount, as well as the harmful release of Zn2+ cations without compromising the corresponding antimicrobial efficiency.
Pressurized Hot Liquid Extraction (PHLE)
PHLE with green solvents has been postulated as the most favorable environmentally friendly method for extracting various compounds from plants and algae. PHLE involves applying solvents at temperatures higher than their boiling point under high pressure (1500 psi) to keep them in a liquid state. These conditions enhance the analyte’s solubility and mass transfer rate, thus reducing extraction times and solvent consumption. Additionally, as PHLE reduces the dielectric constant of water, extractions with water or hydroalcoholic mixtures (e.g., water-glycerol) effectively extract polar and moderately polar compounds.
LUREDERRA will work in the formulation of different matrices natures according to the substrates. LUREDERRA has a deep knowledge in the field of functional coatings. In fact, VIRUPROTECT technology developed by LUREDERRA and commercialized by TECNAN company has demonstrated superior performance to other commercial formulations. VIRUPROTEC technology achieved a 99 % of effectivity versus a 92 % of NANO4HYGIENE product based on SIQUAT technology at 2 hours (virucide activity assessed based on an adaption of ISO 18184:2014 with virus Bacteriophage MS2 ATCC 15597) and obtained a reduction of 6.8 log units (R factor) versus 3.8 in antimicrobial performance for Escherichia coli (ISO 22196).
