Mixed Metal Oxide W-TiO Nanopowder for Environmental Process: Synergy of Adsorption and Photocatalysis.

A mixed metal oxide W-TiO nanopowder photocatalyst was prepared by using the sol-gel method with a broad range of elemental compositions x = C/(C + C), including TiO and WO. The material was structurally characterized and evaluated in adsorption and photocatalytic processes by testing its removal capacity of a representative pollutant methylene blue (MB) in aqueous solutions and under UV-A and sunlight illuminations. The nanopowders appeared to be more effective adsorbents than pure TiO and WO materials, showing a maximum at 15 mol% W, which was set as the tungsten solubility limit in anatase titania.

A Screening Approach to Assess the Impact of Various Commercial Sources of Crude Marine λ-Carrageenan on the Production of Oligosaccharides with Anti-heparanase and Anti-migratory Activities.

Oligosaccharides derived from λ-carrageenan (λ-COs) are gaining interest in the cancer field. They have been recently reported to regulate heparanase (HPSE) activity, a protumor enzyme involved in cancer cell migration and invasion, making them very promising molecules for new therapeutic applications. However, one of the specific features of commercial λ-carrageenan (λ-CAR) is that they are heterogeneous mixtures of different CAR families, and are named according to the thickening-purpose final-product viscosity which does not reflect the real composition.
