Heavy Metal Contamination in Arenillas Ecological Reserve Soils: Correlation and Conservation Impact

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT This study addresses the critical knowledge gap regarding heavy metal contamination in the soils of the Arenillas Ecological Reserve (AERv), located on the southwest coast of Ecuador. Despite being a fragile and highly biodiverse ecosystem, little is known about the magnitude, spatial distribution, and drivers of heavy metal contamination in ...

Microbially Influenced Corrosion in Epoxy‐Ceramic Coated Carbon‐Steel Cooler

open access: yesMaterials and Corrosion, EarlyView.
A significant localization of corrosion attacks up to 1 mm deep were found in coated carbon‐steel cooler. Corrosion products and biofilm were enriched in mixed bacterial community including the genera Sulfuritalea and Methylotenera. Analysis of metabolic markers confirmed their coexistence with sulfate‐reducing bacteria.

Bio‐Based Nanofiber Membranes for Effective Air Filtration: Fabrication and Evaluation of Flame‐Retardant Behavior, Mechanical Properties, and Filtration Performance

open access: yesMacromolecular Materials and Engineering, EarlyView.
The membranes are fabricated from a biodegradable polymer and a bio‐based and inorganic flame‐retardant material in optimized electrospinning conditions to control flammability. Hydrogen bonds between the applied materials improved the mechanical properties and potential exposure to fire. These membranes offer higher filtration quality compared to that

Adsorbable and Antimicrobial Amphiphilic Block Copolymers with Enhanced Biocompatibility

open access: yesMacromolecular Materials and Engineering, EarlyView.
Permanently implanted biomaterials are prone to attract microorganisms and thus represent niches for infections in vivo. Absorbable, antimicrobial polymers have emerged as a promising option. To improve the compatibility of adsorbable antimicrobial polymers with human cells, the block composition of the polycationic segment is modified regarding the ...

Chloromethane‐Enabled Quaternization of Linear Polyglycerol Amines and Their Application as Antibacterial Agents

open access: yesMacromolecular Rapid Communications, EarlyView.
This study details a scalable process for synthesizing quaternary ammonium compounds (QACs) from linear polyglycerols using gaseous chloromethane. The resulting compounds demonstrate effective antibacterial and antibiofilm properties against drug‐resistant S.

Advancements in Magnesium Applications, Biocompatible Implants to Nanoparticles in Medicine and Biomedical Innovations

open access: yesMetalMat, EarlyView.
Magnesium (Mg) and its alloys are identified as prospective materials for orthopedic and cardiovascular applications because of their bio‐corrosiveness and ability to stimulate tissue reparative processes. Although compared with traditional metals, Mg is biocompatible; however, it has various problems that stem from its biodegradation nature, for ...
