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 ...
The geomicrobiology of iron, cobalt, nickel and manganese in lateritic tropical soils from the Santa Elena Peninsula, Costa Rica
(2019)
There is an increasing interest in the biogeochemistry of metals, like cobalt, fuelled by the growing need for batteries and other high technology products. Bioprocessing of Co has been proposed to improve its recovery ...

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 ...
Evaluación de la capacidad del cemento Portland dopado con nanopartículas de TIO2 para la disminución de Pseudomonas aeruginosa y Escherichia coli en agua
(2022-10)
El abastecimiento de agua potable no es equitativo para la población mundial y este problema empeora debido al crecimiento poblacional, a la contaminación, al calentamiento global y a un inadecuado tratamiento de potabilización. ...
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. ...
