Large-scale radiation manufacturing of hierarchically assembled nanogels

2012

Nanogels (NGs), or small particles formed by physically or chemically crosslinked polymer networks, represent a niche in the development of "smart" nanoparticles for drug delivery and diagnostics. They offer unique advantages over other systems, including a large and flexible surface for multivalent bio-conjugation; an internal 3D aqueous environment for incorporation and protection of (bio)molecular drugs; the possibility to entrap active metal or mineral cores for imaging or phototherapeutic purposes; stimuli-responsiveness to achieve temporal and/or site control of the release function and biocompatibility. The availability of inexpensive and robust preparation methodologies is at the ba…

Gelled electrolyte for nanostructured lead-acid battery

2019

In recent years, the storage of energy produced by renewable sources has become a topic of great interest. Lead-acid batteries are widely used in this field, in particular those based on VRLA (Valve-Regulated-Lead Acid) technology, in which the electrolyte is immobilized inside the battery. In this paper, the use of a hydrogel as an electrolyte was considered. Hydrogel can be described as a three-dimensional network of a hydrophilic polymer that can absorb large amounts of water (or aqueous solutions) without dissolving. Pb and PbO2 nanostructured electrodes were used in the battery that used hydrogel as an electrolyte. Two different types of hydrogels were synthesised, both based on PVA th…

Periodically nanostructured hydrogels for ethanol vapors sensing

2013

Chemical sensing using optics has been under extensive research all over the world during last decades and many optical chemical sensors are nowadays finding increasing applications in industry, environmental monitoring, medicine, biomedicine and chemical analysis. These optical sensors can be based on various optical principles, such as absorbance, reflectance or transmittance, luminescence and fluorescence, covering different regions of the spectrum (UV, visible, IR, NIR). Optical chemical sensors have several advantages over conventional electricity-based sensors, in terms of selectivity, immunity to electromagnetic interference, higher sensitivity, and they are also relatively inexpensi…

Self and others in school bullying and cyberbullying : Fine-tuning a new arts-based method to study sensitive topics

2023

Despite continuous international research and prevention efforts, bullying not only persists globally but also evolves into new forms, such as cyberbullying. In this methodological article, we present a new arts-based research tool, graphic vignettes, that can extend our understanding of peer aggression and other sensitive topics by facilitating participants’ creative reflection over the roles of self and others in different problem-based situations. Each graphic vignette, designed for this study, looks like an incomplete comic strip that participants individually develop further. Flexible and open to interpretation vignettes were used in combination with more restrictive/structured vignett…
