Characteristics of the spontaneous deposition of Sn in polycrystalline Pt
(2012-04)Spontaneous deposition of tin (Sn) in polycrystalline platinum (Pt pc) from a sulfuric acid solution of tin salts, was evaluated by conventional electrochemical techniques, to determine its characteristics. Tin was deposited ... -
Cloning, purification and characterization of nigrelysin, a novel actinoporin from the sea anemone Anthopleura nigrescens
(Elsevier B.V., 2019)Actinoporins constitute a unique class of pore-forming toxins found in sea anemones that being secreted as soluble monomers are able to bind and permeabilize membranes leading to cell death. The interest in these proteins ... -
Environmentally relevant concentrations of silver nanoparticles diminish soil microbial biomass but do not alter enzyme activities or microbial diversity
(Elsevier B.V., 2020-06-05)The increasing use of silver nanoparticles (AgNPs) due to their well-known antimicrobial activity, has led to their accumulation in soil ecosystems. However, the impact of environmental realistic concentrations of AgNPs ... -
Fuentes terrestres de contaminación que impactan la zona marino-costera del Golfo de Papagayo, Costa Rica
(Universidad Nacional (Costa Rica), 2019-07)El Golfo de Papagayo, en los últimos años, ha experimentado un acelerado desarrollo socioeconómico que puede ejercer presión sobre sus espacios y recursos naturales, y contribuir, así, al deterioro de su zona ... -
Microhabitat heterogeneity associated with Vanilla spp. and its influences on the microbial community of leaf litter and soil
(Springer Nature, 2020-09)The impact of forest microhabitats on physiochemical properties of the soil and that of microbial communities on tropical soils remain poorly understood. To elucidate the effect of tropical forest stand on leaf litter ... -
Organic amendments exacerbate the effects of silver nanoparticles on microbial biomass and community composition of a semiarid soil
(Elsevier, 2020-11-20)Increased utilization of silver nanoparticles (AgNPs) can result in an accumulation of these particles in the environment. The potential detrimental effects of AgNPs in soil may be associated with the low fertility of soils ... -
Physical, chemical, and biological treatment of chemical waste from teaching laboratories at Universidad Nacional, Costa Rica
(Universidad Nacional, Costa Rica, 2020-07-31)Herein, we report the physical, chemical, and biological treatment of wastewater generated in the teaching laboratories at Universidad Nacional, Costa Rica. Initial physicochemical treatment included neutralization and ...
