Liquid acrylic resin-based composites for marine and renewable energy applications

open access: yes
Rapid growth in the installation of wind and tidal turbines has caused increasing usage of polymer composite materials to manufacture the blades, but the current use of non-recyclable thermoset materials makes composite waste a growing problem.

Effect of zinc oxide nanoparticle concentration coated on acrylic resin upon surface roughness and abrasion resistance

open access: yesMajalah Kedokteran Gigi Indonesia
Acrylic resin is the material most often used as a base for dentures; however, acrylic resin has shortcomings in its biological properties as it does not have antimicrobial properties. ZnO is added to acrylic resin because of its antimicrobial properties.

Photocatalytic Solar Hydrogen Peroxide Production on Donor+Acceptor Linear Polymer Semiconductor Powders Reconfigurable by H‐Bonding and π‐Stacking Interactions

open access: yesAngewandte Chemie International Edition, EarlyView.
A linear polymer, poly(2,3‐dihydroxynaphthalene), when insolubilized, leads to self‐assembly into a hydroquinone–quinone donor+acceptor semiconducting architecture through H‐bonding and π‐stacking interactions. The polymer behaves as a heterogeneous photocatalyst in water for H2O2 production via water oxidation and O2 reduction under visible light.

DIFFERENTIATION OF CHLOROFORM ETCHING TIME ON ACRYLIC RESIN DENTURE TEETH TO SHEAR BOND STRENGTH WITH RESIN COMPOSITE

open access: yes, 2020
Resin composite has become popular in modifying denture element of acrylic resin. Bond strength of the denture element of acrylic resin with the resin composite is weak. Etching materials are needed to strengthen the bond.

Late‐Stage Functionalization of Peptides on the Solid Phase

open access: yesAngewandte Chemie International Edition, EarlyView.
Peptide modifications are essential to control pharmacodynamic and pharmacokinetic properties of peptide drugs. Consequently, strategies that allow for efficient and rapid incorporation of non‐canonical modifications into peptides in parallel formats are highly sought after.

Biobased Polyurethane Films Based on Andiroba (Carapa guianensis) and Buriti (Mauritia flexuosa) Oil Polyols

open access: yesJournal of Applied Polymer Science, EarlyView.
Polyurethane films were prepared from andiroba (Carapa guianensis) and buriti (Mauritia flexuosa) oil‐derived polyols, emphasizing their potential as bio‐based materials. UV–Vis analysis indicates the retention of carotenoid‐related chromophoric features within the polymer matrix.

Evaluation of the Efficiency of a Biobased Reactive Plasticizer on the Morphology and Properties of Sustainable Flexible Films Based on Poly(Lactic Acid) (PLA) Produced by Blown Film Extrusion

open access: yesJournal of Applied Polymer Science, EarlyView.
A comparative investigation of two epoxy additives derived from cardanol (NC513 and NC514s) for production of films based on poly (lactic acid) (PLA), acetyl tributyl citrate (ATBC), and poly (butylene adipate‐co‐terephthalate) (PBAT) clarified their distinct roles, with NC513 mainly acting as a plasticizer, reducing viscosity and enhancing ductility ...
