Magnetically enhanced polymer-supported ceria nanocatalysts for the hydration of nitriles.
2020
The heterogeneous catalysis of the hydration of nitriles to amides is a process of great industrial relevance in which cerium(IV) oxide (also referred to as ceria) has shown an outstanding catalytic performance. The use of non-supported ceria nanoparticles is related to difficulties in the purification of the product and the recovery and recyclability of the catalyst. Therefore, in this work, ceria nanoparticles are supported on a polymer matrix either by synthesizing polymer particles by so-called Pickering miniemulsions while using ceria nanoparticles as emulsion stabilizers or, as a comparison, by in-situ crystallization on preformed polymer particles. The former strategy presents signif…
Nanoscale hybrid silica/polymer Janus particles with a double-responsive hemicorona
2015
Abstract We report a versatile large-scale synthesis strategy for hybrid Janus nanoparticles with a silica core and a unilaterally attached polymer corona in a size range below 100 nm. The stimuli-responsive behavior of these nanoparticles with a poly(2-(dimethylamino)ethyl methacrylate) (PDMAEMA) hemicorona is investigated. The synthesis is based on a modified version of the Pickering emulsion polymerization technique in combination with surface-initiated atom transfer radical polymerization (ATRP) in a “grafting from” approach. In a first step, poly(vinyl acetate) (PVAc) latex particles are prepared via Pickering emulsion polymerization. Colloidal stability is provided by 30 nm silica nan…
Colloidal stability and self-assembling behavior of nanoclays
2020
Abstract Currently, nanoclays are attracting the attention of a wide part of the scientific community, due to some of their most peculiar features that make them good candidates for applications in different fields. In light of this, some strategies can be pursued in order to obtain stable colloidal dispersions of nanoclays with the aim to improve their features and to expand their use. Hence, this chapter presents an overview on the structural and morphological characteristics, the physico-chemical properties and the main approaches that are taken into account for the preparation of homogeneous suspensions of Halloysite, Imogolite and Laponite in both aqueous and apolar solvent media. In p…
Gli atti emulativi
2009
Il lavoro, muovendo da una dettagliata analisi del dato normativo e della elaborazione compiuta dalla dottrina e dalla giurisprudenza, analizza la figura degli atti emulativi, evidenziandone la genesi storica e la riconducibilità alla figura dell'abuso del diritto.

Microencapsulation of Enteric Bacteriophages in a pH-Responsive Solid Oral Dosage Formulation Using a Scalable Membrane Emulsification Process
2019
A scalable low-shear membrane emulsification process was used to produce microencapsulated Escherichia coli-phages in a solid oral dosage form. Uniform pH-responsive composite microparticles (mean size ~100 µ
Pickering Emulsion Gels Based on Halloysite Nanotubes and Ionic Biopolymers: Properties and Cleaning Action on Marble Surface
2019
We have fabricated ecocompatible Pickering emulsions based on halloysite nanotubes and ionic biopolymers (chitosan and pectin) from renewable resources. The effect of pectin and chitosan on the Pickering emulsion was investigated by direct visualization of the oil droplets and by the thermodynamic characterization at the interface. Pectin enhances the Pickering emulsion stability, while a phase separation and nonhomogeneous gel was observed in the presence of chitosan. We have demonstrated that the Pickering emulsion in a pectin based gel phase is suitable for wax layer removal from a marble surface. A controlled cleaning is achieved by tuning the contact time between the gel and the marble…
ANTINFLAMMATORY EFFECT OF LEVORAG (THD) EMULGEL ON RADIATION PROCTOCOLITIS AROUND A COLO-ANAL ANASTOMOSIS: AN INNOVATIVE CASE REPORT
2020
Post-radiation proctitis (PRP) is one of most common complications after abdominal and pelvic radiotherapy for different malignancies. Chronic radiation proctitis (CRP) usually develops 90 days or more after radiation. The present study aimed to show the employment of Levorag Emulgel® (THD S.p.A Correggio, Reggio-Emilia, Italy) as off-label topical treatment, by instillation, to resolve the acute phase of PRP around a coloanal anastomosis, in a patient undergone surgery for an adenocarcinoma of the low rectum, then treated with the Gatekeeper® methodic to resolve fecal incontinence as consequence of the first surgical rectal resection. In conclusion, we can affirm that our methodic could re…
Teātra kritikas funkcijas postdramatiskā teātra laikmetā
2019
Maģistra darbs “Teātra kritikas funkcijas postdramatiskā teātra laikmetā” ir veltīts teātra-skatītāju-kritikas savstarpējām attiecībām. Darba teorētiskajā daļā analizēts teātra teorētiķa Hansa-Tīsa Lēmana (Hans-Thies Lehmann) “postdramatiskā teātra” koncepts. Noskaidrots teātra kritikas jēdziens un galvenās funkcijas. Balstoties uz preses materiāliem un darba autores aptaujā gūtajiem rezultātiem, veikts pētījums, kurā analizētas teātra skatītāju, mākslinieku un kritiķu attiecības, izpratne par teātra kritiku Latvijā mūsdienās – postdramatiskā teātra laikmetā. Kā arī analizētas trīs paaudžu latviešu kritiķu recenzijas, ar mērķi salīdzināt funkciju, pētniecības metožu, postdramatisko elementu…
