Key plant species and detritivores drive diversity effects on instream leaf litter decomposition more than functional diversity: A microcosm study
(Elsevier, 2021-12-01)
Anthropogenic impacts on freshwater ecosystems cause critical losses of biodiversity that can in turn impair key processes such as decomposition and nutrient cycling. Forest streams are mainly subsidized by terrestrial ...
Litter Quality Is a Stronger Driver than Temperature of Early Microbial Decomposition in Oligotrophic Streams: a Microcosm Study
(Springer, 2021-11)
[EN]Litter decomposition is an ecological process of key importance for forest headwater stream functioning, with repercussions for the global carbon cycle. The process is directly and indirectly mediated by microbial ...
Transannular Enantioselective (3 + 2) Cycloaddition of Cycloalkenone Hydrazones under Bronsted Acid Catalysis.
(American Chemical Society, 2021-11-19)
[EN]Hydrazones derived from cycloalkenones undergo an enantioselective transannular formal (3 + 2) cycloaddition catalyzed by a chiral phosphoric acid. The reaction provides high yields and excellent stereocontrol in the ...
Multi-Target Analysis and Suspect Screening of Xenobiotics in Milk by UHPLC-HRMS/MS
(MDPI, 2021-01-26)
The development of suspect or non-target screening methods to detect xenobiotics in biological fluids is essential to properly understand the exposome and assess its adverse health effects on humans. In order to fulfil ...
Slot-Die Process of a Sol–Gel Photocatalytic Porous Coating for Large-Area Fabrication of Functional Architectural Glass
(MDPI, 2021-06-06)
The slot-die process is an appealing technology for the fabrication of coatings on large-area substrates. However, its application on the production of photocatalytic coatings based on sol–gel formulations remains virtually ...
Functionalized Fluorescent Silica Nanoparticles for Bioimaging of Cancer Cells
(MDPI, 2020-09-29)
Functionalized fluorescent silica nanoparticles were designed and synthesized to selectively target cancer cells for bioimaging analysis. The synthesis method and characterization of functionalized fluorescent silica ...
Advances in the Multi-Orthogonal Folding of Single Polymer Chains into Single-Chain Nanoparticles
(MDPI, 2021-01-18)
The folding of certain proteins (e.g., enzymes) into perfectly defined 3D conformations via multi-orthogonal interactions is critical to their function. Concerning synthetic polymers chains, the “folding” of individual ...
Social and Solidarity Economy in Ecuador: Fostering an Alternative Development Model?
(MDPI, 2020-08-24)
The social and solidarity economy (SSE) has gained worldwide attention over the last decade. It represents a host of diverse economic activities which take different forms in each country, but which share solidarity values ...
Extreme temperature events alter stream ecosystem functioning
(Elsevier, 2021-02)
Extreme temperature events have increased in intensity, duration and frequency in the last century, with potential consequences on organisms and ecosystems. In many streams, leaf litter of terrestrial origin is a key ...
Effects of gamma irradiation on instream leaf litter decomposition
(Springer, 2021-12)
[EN]Leaf litter decomposition is a key process in stream ecosystems, the rates of which can vary with changes in litter quality or its colonization by microorganisms. Decomposition in streams is increasingly used to compare ...
