Abstract A novel brush-like poly(2-aminoethyl methacrylate) (PAEMA) was grafted onto chitosan (CS) through gamma radiation-induced polymerization. The copolymer (CS-g-PAEMA) was used to prepare a sodium acetate leached poly(urethane-urea) scaffold. The above derivatives were developed, synthesized, and characterized to meet the specific characteristics of biomaterials. The results revealed that this method is an easy and successful route for grafting PAEMA onto CS. The feasibility of preparing a...

We report the first experimental investigation of porous organic cages (POCs) for the demanding challenge of SO 2 capture. Three isostructural cage molecular materials were studied. An imine functionalized POC (CC3) showed modest and reversible SO 2 capture, while a secondary amine POC (RCC3) exhibited high but irreversible SO 2 capture. A tertiary amine POC (6FT-RCC3) demonstrated very high SO 2 capture (13.78 mmol g -1 ; 16.4 SO 2 molecules per cage) combined with excellent reversibility for a...

Carbon capture utilisation and storage (CCUS) using solid sorbents such as zeolites, activated carbon and Metal–Organic Frameworks (MOFs) could facilitate the reduction of anthropogenic CO2 concentration. Developing efficient and stable adsorbents for CO2 capture as well as understanding their transport diffusion limitations for CO2 utilisation plays a crucial role in CCUS technology development. However, experimental data available on CO2 capture and diffusion under relevant industrial conditio...

Abstract This work aims to study the bio-interfacial properties of poly(ester-urethane) composite scaffolds based on poly (3-hydroxybutyrate) [PHB] and modified by surface plasma-radiation-induced graft polymerization of N-isopropylacrylamide (NIPAAm). The delivering power of the Argon radio-frequency plasma was increased from 5−20 W. The yields over the polyurethane surface, grafting density, topographical dimensions, architecture, surface energy, and wettability were surveyed in the establishe...

NOTT-401 was found to be a highly stable adsorbent for SO2 and CO with excellent cyclability and a straightforward regeneration at room temperature. Moreover, the preferential CO binding sites within the MOF material have been identified by experimental in situ DRIFT spectroscopy coupled with DFT and QTAIM calculations. Such preferential CO adsorption sites were correlated to identify the most significant SO2 interactions within NOTT-401. This study sheds light on the role of the thiophene and h...

Sulfadiazine (SDZ), a bacteriostatic agent, was hosted in a metal–organic framework, specifically in MIL-53(Al) and modified-zinc MIL-53(Al,Zn). Materials were characterized structural, and texturally. Both hosts loaded sulfadiazine but they were differenced regarding the release of sulfadiazine. The presence of zinc plays a significant role to the modulation of sulfadiazine–MOF interactions. Release of sulfadiazine from sulfadiazine@MOFs was monitored in vitro and ex vivo conditions. A kinetic ...

Abstract Samples of fresh and archeological wood were structurally characterized by XPS and NMR spectroscopy. Archaeological wood chips were recovered from excavations in the Great Temple of Mexico City. The presence of a wood consolidant (lactitol trehalose) was studied as a variable, as well as aging. Wood samples oxidized after accelerated aging, and hydrolysis was the first step that promoted oxidation. Consolidation inhibited hydrolysis and, consequently, oxidation of wood, whether contempo...
