Biodiesel via in situ wet microalgae biotransformation: Zwitter-type ionic liquid supported extraction and transesterification

2017

The production of biodiesel derived from microalgae is among the most forthcoming technologies that provide an ecologic alternative to fossil fuels. Herein, a method was developed that enables the direct extraction and conversion of algal oil to biodiesel without prior isolation. The reaction occurs in aqueous media catalyzed by immobilized Candida antarctica lipase B (Novozyme 435). Zwitter-type ionic liquids were used as cocatalyst to improve the selectivity and reactivity of the enzyme. In a model reaction with sunflower oil, 64% biodiesel was obtained. Applying this method to a slurry of whole-cell Chlorella zof ingiensis in water resulted in 74.8% of lipid extraction, with 27.7% biotra…

Maltose-conjugated chitosans induce macroscopic gelation of pectin solutions at neutral pH

2014

Injectable polymer scaffolds are particularly attractive for guided tissue growth and drug/cell delivery with minimally invasive intervention. In the present work, "all-polymeric" gelling systems based on pectins and water-soluble maltose-conjugated chitosans (CM) have been developed. Maltose-conjugated chitosan has been synthesized at three different molar ratios, as evaluated by FITR analysis and fluorimetric titration. A thorough rheological characterization of the blends and their parent solutions has been performed. Macroscopic gelation has been achieved by mixing the high esterification degree pectins with CM at higher maltose grafted to chitosan contents. Gels form in a few minutes a…

Development of antibiotic loaded biodegradable matrices to prevent superficial infections associated to total knee arthroplasty.

2019

Abstract Development of a pharmaceutical form for the superficial infections related with arthroplasties would be helpful for clinical practice. In this context, we set out to evaluate ciprofloxacin and gentamicin elution from systems based on chitosan. Films and semisolid hydrogels containing chitosan alone (2%) or in combination with gelatin (6%) or different proportions (from 12% to 36%) of tetrakis-(hydroxymethyl)-phosphonium-chloride (THPC) were tested as delivery systems. Different antibiotic doses were assayed (0.5 mg/cm2,1 mg/cm2 and 2 mg/cm2). Antibiotic release was studied for each formulation. In vitro cytocompatibility studies and a simulation exercise for bioactivity evaluation…

Strategie formative sui medici potenziali prescrittori per il corretto uso dei test genomici: l'esperienza italiana

2013

Pressioni del mercato, politiche regolatorie, linee guida cliniche e domanda dei consumatori, sono tutti fattori che influiscono sulla conoscenza degli erogatori dell’assistenza sanitaria e sull'uso dei test genetici venduti e/o pubblicizzati direttamente ai consumatori. Obiettivo è presentare un innovativo programma pilota di istruzione e formazione sul corretto uso dei test genomici, dedicato ai potenziali prescrittori, nell'ambito di un progetto finanziato dal Centro Nazionale per il Controllo delle Malattie del Ministero della Salute. Un gruppo di esperti, rappresentanti delle sei regioni coinvolte nel progetto, ha definito i contenuti di un corso modulare concepito per essere somminist…

L'amicizia adolescenziale nella prospettiva delle scienze dell'educazione

2008

L'amicizia è esperienza ricorrente nella vita di molti ragazzi e di molte ragazze che sentono l'urgenza di conferire un senso di unità a tutti gli ambiti della loro esistenza personale, spesso frammentati e disconnessi tra loro. Questa mancanza di unità, che attesta un bisogno di orientamento, sembra essere il "problema fondamentale" dell'adolescente di oggi e, al contempo, la "situazione personale" in cui egli vede la difficoltà e sente la fatica di gestire il suo mondo interiore. La psicologia e la sociologia sanno cogliere le forme autentiche di amicizia che evolvono conformemente allo sviluppo morale, e attestarne al contempo l'esigenza di cura da parte degli educatori. La pedagogia con…

Supported Poly(Ionic Liquid)-Heteropolyacid Based Materials for Heterogeneous Catalytic Fructose Dehydration in Aqueous Medium

2022

Two sets of four different supported catalyst materials were prepared. One set was obtained by polymerization of a bis-vinylimidazolium salt, which formed a poly(ionic liquid) coating on SiO2, TiO2, boron nitride BN, and carbon nitride C3N4. The other set was, instead, obtained by immobilizing Keggin heteropolyacid H3PW12O40 onto poly-imidazolium functionalized materials. All the catalysts, including the bare supports, were subjected to physical and chemical characterization by XRD, SEM, Specific Surface Area and pore size measurements, TGA, FTIR, and acidity-basicity measurements. The catalytic activity of the materials was tested versus the fructose dehydration in water solution at two di…

Oligonucleotides-decorated-poly(N-vinyl pyrrolidone) nanogels for gene delivery

2013

Pulsed electron-beam irradiation of a semi-dilute poly(N-vinyl pyrrolidone) (PVP) aqueous solution in the presence of acrylic acid has led to a carboxyl functionalized nanogel system. Nanoparticles hydrodynamic size and surface charge density, in water and as a function of pH, were investigated by dynamic light scattering and laser doppler velocimetry, respectively. Nanogels (NGs) were proved not to be cytotoxic at the cellular level. Indeed, they rapidly bypass the cellular membrane to accumulate in specific cell portions of the cytoplasm, in the perinuclear area. The availability of pendant carboxyl groups on the crosslinked PVP NGs core prompted us to attempt their decoration with a sing…

Dalla parte di Caino? Aspetti teorici, dati empirici, stereotipi e politiche di intervento sul caso degli uomini maltrattanti

2021

Partendo dai dati empirici raccolti nel corso di un progetto Prin su Rappresentazioni sociali della violenza sulle donne: il caso del femminicidio in Italia – e, in particolare, dai risultati emersi dallo studio sulle rappresentazioni del femminicidio nei procedimenti giudiziari – il saggio affronta il controverso tema del profilo dell’uomo maltrattante intorno al quale si concentrano stereotipi e timori sociali ma la cui conoscenza è un tassello indispensabile per affrontare – con il necessario “distacco analitico” – il fenomeno della violenza di genere, evitando derive esorcizzanti o altrettanto pericolosi scivoloni paternalistici, patologizzanti e moralizzanti. Il quesito centrale riguar…
