Synthesis and Characterization of Stimuli-Responsive Star-Like Polypept(o)ides: Introducing Biodegradable PeptoStars

2017

tar-like polymers are one of the smallest systems in the class of core crosslinked polymeric nanoparticles. This article reports on a versatile, straightforward synthesis of three-arm star-like polypept(o)ide (polysarcosine-block-polylysine) polymers, which are designed to be either stable or degradable at elevated levels of glutathione. Polypept(o)ides are a recently introduced class of polymers combining the stealth-like properties of the polypeptoid polysarcosine with the functionality of polypeptides, thus enabling the synthesis of materials completely based on endogenous amino acids. The star-like homo and block copolymers are synthesized by living nucleophilic ring opening polymerizat…

Biopolymeric bilayer films produced by co-extrusion film blowing

2018

Abstract Biodegradable packaging promises a more environmentally friendly future. Nevertheless, a single biopolymer often lacks of some important properties. In order to contribute to this challenge, biodegradable bilayer films from poly(lactic acid) (PLA) and MaterBi® were prepared in this work and compared with monolayer films obtained with both the polymers. The prepared films were fully characterized through morphological, mechanical, thermal, chemical, optical and water contact angle analyses. Furthermore, the hydrolytic degradation of monolayer and bilayer films was studied by performing tests at three different pH. The morphological analysis revealed that PLA/MaterBi bilayer films sh…

Hydrolysis of DCNP (a Tabun mimic) catalyzed by mesoporous silica nanoparticles

2015

[EN] The hydrolysis of diethylcyanophosphonate, DCNP (a Tabun simulant) in the presence of mesoporous silica nanoparticles (MSN) has been studied in acetonitrile:water (99.5:0.5 v/v) mixtures using 31P NMR as a suitable technique to follow the DCNP hydrolysis. MSN alone was not capable to induce DCNP hydrolysis, yet MSN in combination with the presence of the bases potassium carbonate, triethylamine or DABCO enhanced DCNP degradation. When MSN was used combined with K2CO3, a hydrolysis of ca. 95% of the initial DCNP after 60 min was observed. In the presence of DABCO, MSN was able to induce the hydrolysis of ca. 90% of DCNP after the same time. However, the DCNP hydrolysis using MSN in the …

Designed biodegradable hydrogel structures prepared by stereolithography using poly(ethylene glycol)/poly(D,L-lactide)-based resins

2010

Designed three-dimensional biodegradable poly(ethylene glycol)/poly(D,L-lactide) hydrogel structures were prepared for the first time by stereolithography at high resolutions. A photo-polymerisable aqueous resin comprising PDLLA-PEG-PDLLA-based macromer, visible light photo-initiator, dye and inhibitor in DMSO/water was used to build the structures. Porous and non-porous hydrogels with well-defined architectures and good mechanical properties were prepared. Porous hydrogel structures with a gyroid pore network architecture showed narrow pore size distributions, excellent pore interconnectivity and good mechanical properties. The structures showed good cell seeding characteristics, and human…

INCANDIDABILITÀ DEGLI AMMINISTRATORI EX ART. 143, COMMA 11, T.U.E.L. ALLA LUCE DELLE MODIFICHE INTRODOTTE DAL D.L. N. 113/2018 E DELLE PROPOSTE DI LE…

2019

L’art. 143 del d.Lgs. n. 267/2000 attribuisce al governo il potere di sciogliere i consigli comunali e provinciali in conseguenza di fenomeni di infiltrazione e condizionamento di tipo mafioso. Una delle conseguenze è l’incandidabilità temporanea degli amministratori “responsabili delle condotte che hanno dato causa allo scioglimento” del Consiglio dell’ente locale (art. 143, comma 11), dichiarata dal tribunale civile con procedimento in camera di consiglio (artt. 737 ss. c.p.c.). Lo scioglimento ex art. 143 costituisce una misura di carattere eccezionale e cautelare. Tale istituto, nato in uno dei momenti più difficili della lotta alla mafia, è stato, sin da subito, oggetto di dibattito in…
