Dye‐sensitized Devices: Photovoltaic and Photoelectrolytic Applications
(2018-11)
Dye‐sensitized approach along with stability and surface robustness in titanium dioxide (TiO2) against photocorrosion and degradation has been widely studied and applied in several important applications. This chapter ...
Richness and metallo-tolerance of cultivable fungi recovered from three high altitude glaciers from Citlaltépetl and Iztaccíhuatl volcanoes (Mexico)
(2020)
In Mexico little is known about high-altitude glacial psychrotolerant or psychrophilic fungal species, with most glacial fungi isolated from polar environments or Alpine glaciers. It has been documented that some of these ...
Bioactivity of prenylated hydroxybenzoic acids from Piper garagaranum C. DC
(2022)
A bio-assay guided fractionation of Piper garagaranum C. DC. led to the isolation of two prenylated hydroxybenzoic
acids (1-2) with anti-inflammatory and cytotoxic activities. The anti-inflammatory action was determined
in ...
From Ideality to Simplicity: A Robust and Affordable Hydrogen Reference Electrode
(2020-02-01)
In electrochemistry, the concept of a reference electrode is fundamental. Introductory courses might mention the standard hydrogen electrode (SHE), its working principle, and its theoretical design; however, chances are ...
The role of chloramine species in NDMA formation
(2018-09)
N-nitrosodimethylamine (NDMA), a probable human carcinogen disinfection by-product, has been
detected in chloraminated drinking water systems. Understanding its formation over time is important
to control NDMA levels in ...
Empleo de técnicas y materiales biológicos en la búsqueda de productos activos contra la malaria
(2001)
Se describen los métodos empleados en el estudio del efecto de extractos de insectos preparados en el Instituto Nacional de Biodiversidad de Costa Rica, sobre un tipo de malaria murina producida por el Plasmodium bergheim. ...
Room temperature gas-solid reaction of titanium on glass surfaces forming a very low resistivity layer
(2016-09)
Titanium films were deposited on quartz, glass, polyamide and PET substrates in a high vacuum system at room temperature and their electrical resistance monitored in vacuo as a function of thickness. These measurements ...
Phytochemical study of endemic Costa Rican Annonaceae species Annona pittieri and Cymbopetalum costaricense
(2021)
Phytochemical profile of the Central American rainforest endemic Annonaceae species, Annona pittieri and Cymbonopetallum costaricense, were studied in search
of novel bioactive compounds. The acetogenin squamocin (1) ...
Reactivity and structure of derivatives of 2-hydroxy-1,4-naphthoquinone (lawsone)
(2007-11)
The structures of two derivatives of 2-hydroxy-1,4-naphthoquinone (lawsone) are examined using the density functional theory (DFT) hybrid functional B3LYP. Using the optimized structure of lawsone acetate, the reactivity ...
Expanding the Trichoderma harzianum species complex: Three new species from Argentine natural and cultivated ecosystems
(2021-06-22)
A study was performed on a collection of 84 isolates from decaying plant tissues and soils in
Argentina previously identified as Trichoderma harzianum. Based on multiple phenotypic characters
and multilocus phylogenetic ...
