Assessment of Methacrylated Poly(ε‐Caprolactone)/Silanized Hydroxyapatite Composite Resin for High‐Resolution Scaffolds via Vat Photopolymerization 3D Printing

open access: yesPolymers for Advanced Technologies, Volume 37, Issue 2, February 2026.
ABSTRACT High‐resolution, biocompatible scaffolds are essential for reproducible tissue engineering and remain challenging to fabricate with vat photopolymerization due to cure‐depth control and limited bioactivity of neat polymers. This work investigated the mechanical, surface, and biological properties, as well as the high‐resolution 3D printability,

Emergence of Livestock‐Associated Methicillin‐Resistant Staphylococcus aureus ST398 in Wild Birds, Brazil

open access: yesMicrobiologyOpen, Volume 14, Issue 6, December 2025.
In a protected forest fragment in southern Brazil, 197 wild birds were sampled, with 12.2% carrying Staphylococcus aureus. Two MRSA ST398 strains, the first reported in Brazilian wild birds, were identified. Genomic analysis revealed resistance and virulence genes, linking these strains to pigs and underscoring the critical need for resistance ...

Sustainable biofuel production from fish processing waste: lipase‐catalyzed hydroesterification of tilapia residual oil

open access: yesBiofuels, Bioproducts and Biorefining, Volume 19, Issue 6, Page 1948-1969, November/December 2025.
Abstract Fishing waste and byproducts, whether naturally occurring or from industrial processing, are important sources of high‐value compounds. Fertilizers, biomaterials, cosmetics, biolubricants, and biodiesel are some of the substances that can be obtained from these residues. The objective of this study was to conduct a theoretical and experimental

Improving the Chain Sampling Plans Based on Cpm Index

open access: yesQuality and Reliability Engineering International, Volume 41, Issue 6, Page 2601-2609, October 2025.
ABSTRACT A recent article discusses the design of chain sampling plans based on the Cpm index where a sample is randomly selected from the lot, and the Cpm value of the sample is compared with the threshold (ka). If the Cpm is lower than ka, the lot is rejected, otherwise, the Cpm values of previous m lots are examined; if m‐1 of the Cpm values exceed ...

Growth of Carbon Nanotubes on Co(x)‐Ni(1‐x) Ferrites by Chemical Vapor Deposition and Performance on Catalytic Wet Peroxide Oxidation

open access: yesChemCatChem, Volume 17, Issue 16, August 18, 2025.
This study presents a sustainable approach for synthesizing carbon nanotubes (CNTs) via chemical vapor deposition (CVD) using polyolefins as model plastic waste as the carbon source and Ni─Co ferrite catalysts. The CNTs were applied in catalytic wet peroxide oxidation (CWPO) to degrade bisphenol A (BPA) and sulfamethoxazole (SMX), achieving efficient ...

Critical monitoring and control factors for achieving food defense criteria

open access: yesRisk Analysis, Volume 45, Issue 8, Page 2427-2441, August 2025.
Abstract Food can be contaminated by physical, chemical, biological, and radiological hazards. Industry and regulatory agencies have developed the Food Safety Management System, based on the principles of Hazard Analysis and Critical Control Points, to be effective against unintentional food safety risks. However, there is the intentional contamination

Decoding Brazil's bean belt: Spatiotemporal patterns, production systems and the pulse of bean production (2011–2022)

open access: yesGeo: Geography and Environment, Volume 12, Issue 2, July‐December 2025.
Short Abstract This study aimed to map consolidated bean production areas in Brazil and analyse their spatial‐temporal evolution from 2011 to 2022. Based on autocorrelation and relative frequency patterns, four primary bean belts were identified: South, Central Brazil, Mato Grosso and Northeast.
