Evaluation of Gas Hydrates Operation Zone to Establish an Optimal Hydrate Management Strategy
Needleless electrospun nanofibers containing microcapsules: a methodology for self-supported microcontainers
Using nanotechnology to remove ice from structures
Uptake and Toxicity of Methylmethacrylate-Based Nanoplastic Particles in Aquatic Organisms. In MICRO 2016. Fate and Impact of Microplastics in Marine Ecosystems
In the present study, the uptake and toxicity of two poly(methylmethacrylate)-based plastic nanoparticles (PNPs) with different surface chemistries (medium and hydrophobic) was assessed using aquatic organisms selected for their relevance based on the environmental behaviour of the PNPs. Pure poly...

Nanoparticle-stabilized microbubbles for multimodal imaging and drug delivery
Microbubbles (MBs) are routinely used as contrast agents for ultrasound imaging. The use of ultrasound in combination with MBs has also attracted attention as a method to enhance drug delivery. We have developed a technology platform incorporating multiple functionalities, including imaging and...
