Microgel structure-driven linear and non-linear mechanical properties of self-assembled microgel films
Soft self-supported cohesive films were formed by self-assembly of pH- and thermo-responsive P(MEO2MA-co-OEGMA-co-MAA) microgels without any preparation and/or post-treatments. Linear and non-linear mechanical properties of those films were characterized respectively by dynamic mechanical measurements at low strain and uniaxial extensional tests at...
Fungi in PAH-contaminated marine sediments: Cultivable diversity and tolerance capacity towards PAH
The cultivable fungal diversity from PAH-contaminated sediments was examined for the tolerance to polycyclic aromatic hydrocarbon (PAH). The 85 fungal strains, isolated in non-selective media, revealed a large diversity by ribosomal internal transcribed spacer (ITS) sequencing, even including possible new species. Most strains (64%) exhibited PAH-t...

Speciation of essential nutrient trace elements in coconut water
Coconut water (Cocos Nucifera) is shown to be a source of essential elements present in the form of low-molecular weight stable complexes known for their bio-availability. The total element concentrations were in the range of 0.2–2.7, 0.3–1, 3–14 and 0.5–2 ppm for Fe, Cu, Mn, and Zn, respectively, and varied as a function of the origin of the nut a...
Metagenomic exploration of multi-resistance genes linked to microbial attributes in active nonferrous metal(loid) tailin...
Mine tailings sites are considered as a continuous source of discharged metal(loid)s and residual organic flotation reagents. They are extremely toxic environments representing unique ecological niches for microbial communities. Mine tailings as a source of multi-resistance genes have been poorly investigated. Metagenomic analysis for four active n...
Heavy metal contents in soils and native flora inventory at mining environmental liabilities in the Peruvian Andes
Inadequate waste management in Mining Environmental Liabilities (MEL) represents a risk for the environment and human health and generates social problems. The aim of this article is twofold: i) to evaluate the environmental quality of soils from a geo-ecological perspective; and ii) to inventory native flora around two MEL in the Hualgayoc distric...

Covalent and Ionic Bonding between Tannin and Collagen in Leather making and shrinking: A MALDI-ToF study
Collagen powder hydrolysates were reacted with a solution of commercial mimosa bark tannin extract. The mix- ture was prepared at ambient temperature and prepared at 80°C to determine what reactions, if any, did occur between the collagen protein through its amino acids and the polyphenolic condensed tannin. The reaction pro- ducts obtained were an...
