Unveiling the interplay between homogeneous and heterogeneous catalytic mechanisms in copper-iron nanoparticles working under chemically relevant tumour conditions

  • 21/06/2022
  • Comments off

In this work we have designed a bimetallic catalyst nanoparticle containing Cu and Fe species and we describe how homogeneous and heterogeneous processes involving gluthatione are coupled and fostered in the tumor microenvironment.

Formamidinium halide salts as precursors of carbon nitrides

  • 17/06/2022
  • Comments off

Pyrolysis of formamidinium halide salts (FAI, FABr) results in a new type of amorphous carbon nitride materials with a mass fraction of 40–50% nitrogen content. Pyrolysis temperature drives final chemical composition, morphology, optical and electrical properties of the material independently of the halide precursor and identi­fying triazine ring, instead of typical heptazine unit, as the […]

Antimicrobial Electrospun Polycaprolactone-Based Wound Dressings: An In Vitro Study About the Importance of the Direct Contact to Elicit Bactericidal Activity

  • 27/01/2020
  • Comments off

Using electrospinning we were able to prepare wound dressings with antimicrobial action thanks to their large surface per volume ratio, which allows their loading with therapeutic amounts of active principles. By nuclear magnetic resonance we demonstrated that the antimicrobial compounds are donors of hydrogen bonds to the ester functional group in PCL, which acts as […]

Selective delivery of photothermal nanoparticles to tumors using mesenchymal stem cells as Trojan horses

  • 27/01/2020
  • Comments off

The main challenge of cancer treatment is to avoid or minimize systemic side effects in off-target tissues. Mesenchymal stem cells (MSCs) can be used as therapeutical carriers because of their ability to migrate and incorporate into inflammation areas including tumors. Here, this homing ability is exploited by carrying therapeutic nanoparticles (Hollow Gold Nanoparticles (HGNs)) following […]

Microwave-activated structured reactors to maximize propylene selectivity in the oxidative dehydrogenation of propane

  • 27/01/2020
  • Comments off

Microwave (MW) heating has been applied to increase the selectivity to propylene in the oxidative dehydrogenation (ODH) of propane. The preferential heating of the solid monolith (made of SiC, a good microwave susceptor), allows working with a lower gas phase temperature, reducing the formation of undesired by-products in the gas phase via homogeneous reactions. Full […]

  • Comments off

The deposition of airborne nanosized matter onto surfaces could pose a potential risk in occupational and environmental scenarios. The incorporation of fluorescent labels into spherical 80-nm silica nanoparticles allowed their detection after LED light illumination. Full article here.

Photocatalytic and antimicrobial multifunctional nanocomposite membranes for emerging pollutants water treatment applications

  • 27/01/2020
  • Comments off

Emerging pollutants represent a new global problem for water quality. As these compounds get into the environment, they cause severe threats to aquatic environments and human health and are typically resistant to conventional wastewater treatments. Full article here.
