Sustainable catalysis by polymer supported gold nanoparticles
(Universita degli studi di Salerno, 2016-03-16)
Gold Nanoparticles are nanomaterials whose properties are completely different from the ones of the bulk material. Nowadays many chemists have been using them as catalysts which work under mild conditions and respect the ...
Fluorescence-based sensors for the detection of biologically and environmentally relevant molecules
(Universita degli studi di Salerno, 2016-03-15)
Hydrogen sulfide (H2S) has been known for long time as a toxic molecule in biological systems. More recent studies have shown that mammals can produce H2S in a controlled fashion, suggesting that it’s important in maintaining ...
Development of iron-based catalysts for the coupling of carbon dioxide with epoxides
(Universita degli studi di Salerno, 2018-03-07)
Beside the environmental and energetic issues, carbon dioxide can
be considered as a resource. Many chemical transformations based
on CO2 as C-1 building block have been developed. The coupling
reaction of epoxides with ...
Sviluppo di nuovi sistemi catalitici dei metalli del gruppo 4 per la polimerizzazione di monomeri olefinici e polari
(Universita degli studi di Salerno, 2016-03-18)
In this PhD work, a series of eight new group 4 metal complexes 1−8 (1 = (t- BuOS)2TiCl2; 2 = (CumOS)2TiCl2; 3 = (t-BuOS)2Zr(CH2Ph)2; 4 = (CumOS)2Zr(CH2Ph)2); 5 = (t-BuOS)2Ti(OiPr)2; 6 = (t-BuOS)2Zr(OtBu)2; 7 = (t- ...
Synthesis of sustainable polyesters via ring opening polymerization promoted by phenoxy-imine aluminum complexes
(Universita degli studi di Salerno, 2019-02-04)
Aliphatic polyesters are emerging as an important class of materials alternatives to te petroleum-based polymers. They are often biodegradable and can be produced from renewable feedstocks. In this context, the developmentof ...
CO2 fixation in cyclic carbonates and polycarbonates by salen-like based metal complexes
(Universita degli studi di Salerno, 2019-02-06)
At the current rate of consumption of petroleum resources, they are predicted to be exhausted within the next century. For this reason, the development of new chemical processes using biorenewable resources is attracting ...
Supported gold nanoparticles as promising catalysts in sustainable organic synthesis
(Universita degli studi di Salerno, 2021-03-23)
Gold nanoparticles (AuNPs) emerged as very promising catalysts in a lot of organic reactions and industrial
applications. These catalysts are in fact capable of catalysing chemical processes under mild conditions ...
Complexes of coinage metals stabilized by N-heterocyclic carbenes: catalytic and biological activities
(Universita degli studi di Salerno, 2022-05-30)
Since the synthesis, the isolation, and the characterization of the first stable N-heterocyclic carbene (NHC) in
1991 by Arduengo and collaborators, this class of ligands has attracted the attention of researchers for ...
Isolation and characterization of lignins from Wheat straw and cardoon biomasses
(Universita degli studi di Salerno, 2023-03-13)
The progressive reduction in the availability of oil resources, the unstoppable increase in their costs
and the growing need for efficient environmental protection, imply an urgent development of new
technologies for the ...
Sustainable approaches for the synthesis and the chemical degradation of polyesters
(Universita degli studi di Salerno, 2023-03-03)
Petrochemical-based plastics have a significant impact on modern society, as underlined by their high
production and countless applications. Indeed, the production of plastics has increased over the past 50 years,
reaching ...
