Experimental Comparative Analysis of Hole‐Making Strategies and Cutting Parameters on Flexural Properties and Induced Delamination in S2 Glass and Basalt Fiber‐Reinforced Polymers

Polymer Composites, EarlyView.
Hole‐making strategy and machining parameters influence delamination and hole quality in S2‐glass and basalt FRP composites, which subsequently affet flexural performance. Improved hole integrity leads to enhanced structural performance during three‐point bending.

Combined Effects of Thermal Cycling Aging and Reinforcement Content on the Ball‐On‐Disk Wear of Additively Manufactured Polylactic Acid Composites

Polymer Composites, EarlyView.
Thermal Aging and Tribological Tests of Additive Manufactured PLA Composites. ABSTRACT This study focuses on the additive manufacturing of pure polylactic acid (PLA) specimens and milled glass fiber (GF)‐filled PLA composites under thermal cycling aging and wear tests. Wear tracks have been analyzed via 3D optical profiling and SEM imaging.

Optimization of the Culture Medium for the Production of β-Galactosidase from Kluyveromyces marxianus CCT 7082

Food Technology and Biotechnology, 2008
Seven strains of the genus Kluyveromyces were screened for β-galactosidase activity in a synthetic medium. Kluyveromyces marxianus CCT 7082 was selected as the best enzyme producer for optimization of the culture medium.

Biosurfactant production by Pseudomonas aeruginosa isolated from mining waste: From genomic analysis to development of a polymeric composite for removal of hexavalent chromium

Polymer International, EarlyView.
Biosurfactant was produced by Pseudomonas aeruginosa using andiroba waste from Amazonia. A biosurfactant–alginate composite (Alg/BioS) was successfully synthesized via ionotropic gelation, and achieved up to 70% Cr6+ removal from water. Abstract Environmental contamination by heavy metals represents a significant challenge due to their persistence in ...

Statistical evaluation of nylon chemical recycling through acidolysis

Polymer International, EarlyView.
Sustainable PA6 recycling through acidolysis enabled temperature‐driven depolymerization, modeled by regression analysis. Recycled products successfully replaced up to 30% monomer while preserving PA6 chemical composition or crystalline structure. Abstract This study focuses on the sustainability of plastics reporting the recycling of polyamide (PA ...
