GREEN SYNTHETIC PLATFORM FOR THE PREPARATION OF VARIOUS XANTHOPHYLL ESTERS

Xanthophylls are oxygenated derivatives of carotenoids and, as natural biologically active compounds with known pharmacological properties, they have many positive effects on human health. For some esterified xanthophylls it was shown that they have superior stability and bioavailability compared to their free form. We have developed an energy-efficient and environmentally friendly synthetic platform for the preparation of a variety of xanthophyll esters. This platform can be applied to pigments in pure form (eg., lutein, zeaxanthin, β-cryptoxanthin, capsanthin, violaxanthin), but extracts…

ACTIVE BIOFOIL WITH INCORPORATED ANTIOXIDANT JAPANESE KNOTWEED RHIZOME BARK EXTRACT

The invention is biodegradable chitosan-based foil, which is enriched with a potent antioxidant plant extract, obtained from an invasive plant species, Japanese knotweed (Polygonum cuspidatum, Fallopia japonica Houtt.), which due to its fast expansion poses global ecological damage, displaces autochthonous plants and leads to a reduction in biodiversity. Moreover, it is causing huge economic harm (e.g. damage to infrastructure).

Hydrodynamic cavitation wastewater treatment

Our invention is an alternative technological solution: a new and efficient combination of hydrodynamic cavitation, photochemical and photocatalytic processes. It is a combination of green oxidation processes that do not require the addition of external oxidants, and thus do not contribute to the formation of secondary pollutants in the treated sample.

Vanillin

Lignin is a source of many useful chemicals, such as vanillin, vanillic acid, phenol, etc. The innovation from the University of Ljubljana represents the conversion of lignin and ferulic acid into vanillin using hydrogen peroxide as an oxidant and vanadium oxide as a catalyst.

Process for preparation of functionalized superparamagnetic adsorbents with precursor trimethoxy (1H, 1h, 2H, 2H-nonafluorohexyl) silane (NFHTMS)

Classical methods of cleaning oil spills do not give satisfactory results in removing oil from water, but the functional nanomaterials show the potential to be able to become cost effective and environmentally friendly solutions. The invention is based on the problem of how to synthesize nanoparticles so that they will have such physicochemical properties that will be useful for the adsorption of oil stains / spills in water. The nanoparticles are supposed to have an iron oxide spinel crystal structure…

Axisymmetric chiral auxetic structure

The present invention relates to an axisymmetric chiral auxetic structure. The invention belongs to the field of materials design. The invention is an axisymmetric chiral cellular structure with a cylindrical or spherical shape consisting of equal or variable unit chiral cells. The structure exhibits auxetic deformation behaviour with negative Poisson’s ratio in all polar or spherical coordinate directions upon mechanical loading. The deformation of the cylindrical chiral auxetic structure is isotropic in the radial direction under axial loading.
