Sustainable Materials and Chemical Processes for Additive Manufacturing
(ACS, 2020-08-03)
Additive manufacturing (AM) is energizing the fields of chemistry and materials science to develop new inks for new applications within fields such as aerospace, robotics, and healthcare. AM enables the fabrication of ...
Insights on the Atmospheric-Pressure Plasma-Induced Free-Radical Polymerization of Allyl Ether Cyclic Carbonate Liquid Layers
(MDPI, 2021-08-25)
Plasma-induced free-radical polymerizations rely on the formation of radical species to initiate polymerization, leading to some extent of monomer fragmentation. In this work, the plasma-induced polymerization of an allyl ...
Enantioselective Ring-Opening Polymerization of rac-Lactide Dictated by Densely Substituted Aminoacids
(ACS, 2017-03-08)
Organocatalysis is becoming an important tool in
polymer science because of its versatility and specificity. To date
a limited number of organic catalysts have demonstrated the
ability to promote stereocontrolled ...
Packaging materials with desired mechanical andbarrier properties and full chemical recyclability
(Nature, 2019-08-08)
Plastics have become indispensable in modern life and the material of choice in packaging applications, but they have also caused increasing plastic waste accumulation in oceans and landfills. Although there have been ...
Polyether Single and Double Crystalline Blends and the Effect of Lithium Salt on Their Crystallinity and Ionic Conductivity
(MDPI, 2021-06-25)
In this work, blends of Poly(ethylene oxide), PEO, and poly(1,6-hexanediol), PHD, were prepared in a wide composition range. They were examined by Differential Scanning Calorimetry (DSC), Polarized Light Optical Microscopy ...
Mechanistic studies of a lipase unveil effect of pH on hydrolysis products of small PET modules
(Nature, 2023-06)
Biocatalysis is a key technology enabling plastic recycling. However, despite advances done in the development of plastic-degrading enzymes, the molecular mechanisms that govern their catalytic performance are poorly ...
Bio-based non-isocyanate poly(hydroxy urethane)s (PHU) derived from vanillin and CO2
(Royal Society of Chemistry, 2023-06)
As an alternative to the use of hazardous phosgene-based isocyanates for polyurethane preparation, non-isocyanate poly(hydroxy urethanes) (PHU) based on 5-membered cyclic carbonates have been developed. However, to date, ...
Upgrading Polyurethanes into Functional Ureas through the Asymmetric Chemical Deconstruction of Carbamates
(American Chemical Society, 2023-01)
The importance of systematic and efficient recycling of all forms of plastic is no longer a matter for debate. Constituting the sixth most produced polymer family worldwide, polyurethanes, which are used in a broad variety ...
Influence of FFF Process Conditions on the Thermal, Mechanical, and Rheological Properties of Poly(hydroxybutyrate-co-hydroxy Hexanoate)
(MDPI, 2023-04-07)
Polyhydroxyalkanoates are natural polyesters synthesized by microorganisms and bacteria. Due to their properties, they have been proposed as substitutes for petroleum derivatives. This work studies how the printing conditions ...
From Plastic Waste to New Materials for Energy Storage
(Royal Society of Chemistry, 2022-07-06)
The use of plastic waste to develop high added value materials, also known as upcycling, is a useful strategy towards the development of more sustainable materials. More specifically, the use of plastic waste as a feedstock ...
