Fundamentals of silicene
(2017-08-02)Silicene is a single atomic layer of silicon (Si) much like graphene, the first example of an elemental twodimensional (2D) nanomaterial whose study led to the 2010 Nobel Prize in Physics. Until 2010 or so, the only known ... -

(1985)Este libro es una introducción a la Química Orgánica, para estudiantes de carreras médicas, Microbiología, Biología, Agricultura, Veterinaria. Llena un vacío entre textos escolares y libros de texto de la carrera de Química. -
Fungal and Bacterial Co-Bioaugmentation of a Pesticide-Degrading Biomixture: Pesticide Removal and Community Structure Variations during Different Treatments | SpringerLink
(Springer, 2021)Biopurification systems (BPS) are employed for the treatment of pesticide-containing wastewaters. In this work, a biomixture (active core of BPS) complemented by the addition of the fungus Trametes versicolor was evaluated ... -
Fungal bioaugmentation of two rice husk-based biomixtures for the removal of carbofuran in on-farm biopurification systems
(2016-02)The ligninolytic fungus Trametes versicolor was employed in the bioaugmentation of compost- (GCS) and peat-based (GTS) biomixtures for the removal of the insecticide-nematicide carbofuran (CFN). Among several lignocellulosic ... -
Fungal communities in feces of the frugivorous bat Ectophylla alba and its highly specialized Ficus colubrinae diet
(2022)Background: Bats are important long-distance dispersers of many tropical plants, yet, by consuming fruits, they may disperse not only the plant’s seeds, but also the mycobiota within those fruits. We characterized the ... -
Fungal Communities in Sediments Along a Depth Gradient in the Eastern Tropical Pacific
(2020-11-06)Deep waters represent the largest biome on Earth and the largest ecosystem of Costa Rica. Fungi play a fundamental role in global biogeochemical cycling in marine sediments, yet, they remain little explored. We studied ... -
Fungal Endophytes and Their Bioactive Compounds in Tropical Forests of Costa Rica
(2021-04-15)We present a glimpse of the diversity of endophytic fungi in the tropical forests of Costa Rica and some examples of bioactive compounds obtained from them. We include the characterization of isolates carried out mainly ... -
FungalTraits: a user-friendly traits database of fungi and fungus-like stramenopiles
(2021-01-19)The cryptic lifestyle of most fungi necessitates molecular identification of the guild in environmental studies. Over the past decades, rapid development and affordability of molecular tools have tremendously improved ... -
Fungi for the bioremediation of pharmaceutical-derived pollutants: A bioengineering approach to water treatment
(2021-07-01)The excessive amount of pharmaceutical compounds (PhCs) released into aquatic environments poses a risk to humans, wildlife, and environmental health. It is a serious problem that requires urgent attention. In this work, ... -
Fungi in aquatic ecosystems
(2019-03)Fungi are phylogenetically and functionally diverse ubiquitous components of almost all ecosystems on Earth, including aquatic environments stretching from high montane lakes down to the deep ocean. Aquatic ecosystems, ... -
Fungi increases kelp (Ecklonia radiata) remineralisation and dissolved organic carbon, alkalinity, and dimethylsulfoniopropionate (DMSP) production
(2023-09)Fungi are key players in terrestrial organic matter (OM) degradation, but little is known about their role in marine environments. Here we compared the degradation of kelp (Ecklonia radiata) in mesocosms with and without ... -
Fungi with history: Unveiling the mycobiota of historic documents of Costa Rica
(2022-06-12)Through nondestructive techniques, we studied the physicochemical characteristics and mycobiota of five key historic documents from Costa Rica, including the Independence Act of Costa Rica from 1821. We determined that for ... -
Further disentangling of a taxonomic puzzle: Maxillaria Ramosa, Ornithidium Pendulum, and a new species, O. Elianae (Orchidaceae)
(Harvard Papers in Botany, 2008)McIllmurray and Oakeley (2004) demonstrated that the name Maxillaria ramosa has been misapplied to Ornithidium pendulum since 1967, and possibly corresponds to M. cassapensis. We refer Ornithidium ochraceum, O. loefgrenii, ... -
Fusarium: more than a node or a foot-shaped basal cell
(2021)Recent publications have argued that there are potentially serious consequences for researchers in recognising distinct genera in the terminal fusarioid clade of the family Nectriaceae. Thus, an alternate hypothesis, namely ... -
Future Changes in Simulated Streamflow in Costa Rica from CMIP6 climate models
(2022-06-21)Statistically downscaled daily data from an ensemble of five General Circulation Models (GCMs) from the Climate Model Intercomparison Program 6 (CMIP6) will be used to determine changes (with respect to a baseline historical ... -
Future changes in the ecosystem services at Guanacaste Conservation Area, Costa Rica and their implications for the nearby communities of the Central American Dry Corridor
(2022)We present a valuation of the main ecosystem services of the Rincon de la Vieja National Park (RVNP), as part of the Guanacaste Conservation Area (GCA) in the North Pacific of Costa Rica. The analysis consisted of an ... -
G17.8 + 16.7: A new supernova remnant
(2021)Non-thermal radio emission is detected in the region of the gamma-ray source FHES J1723.5 − 0501. The emission has an approximately circular shape 0.8° in diameter. The observations confirm its nature as a new supernova ... -
G279.0+1.1: a new extended source of high-energy gamma-rays
(2020)G279.0+1.1 is a supernova remnant (SNR) with poorly known parameters, first detected as a dim radio source and classified as an evolved system. An analysis of data from the Fermi-Large Area Telescope (LAT) revealing for ... -
Gaschromatographische Analyse des Samenfettes der mittelamerikanischen Fevillea Cordifolia (Cucurbitaceae)
(1992)The fat of the seeds of Fevillea cordifolia was extracted under exclusion of oxygen and light and then characterized by 13C-NMR in regard to the contained unsaturated acid moieties. The total fat was separated by HPLC to ... -
Gastric cancer in the era of immune checkpoint blockade
(2019-09-24)Gastric cancer (GC) is one of the most important malignancies worldwide because of its high incidence and mortality. The very low survival rates are mainly related to late diagnosis and limited treatment options. GC is the ...
