Electric-field control of single-molecule tautomerization
(2020)
The electric field is an important parameter to vary in a single-molecule experiment, because it can directly affect the charge distribution around the molecule. Yet, performing such an experiment with a well-defined ...
Hot carrier extraction from multilayer graphene
(2016)
Hot carriers in semiconductor or metal nanostructures are relevant, for instance, to enhance the activity of oxide-supported metal catalysts or to achieve efficient photodetection using ultrathin semiconductor layers. ...
Thin-layer black phosphorus/GaAs heterojunction pn diodes
(2015)
Owing to its high carrier mobility and thickness-tunable direct band gap, black phosphorus emerges as a promising component of optoelectronic devices. Here, we evaluate the device characteristics of p-n heterojunction ...
Chemical modification of graphene via hyperthermal molecular reaction
(2014)
Chemical functionalization of graphene is achieved by hyperthermal reaction with azopyridine molecular ions. The one-step, room temperature process takes place in high vacuum (10–7 mbar) using an electrospray ion beam ...
High Performance Graphene–Oxide–Metal Diode through Bias‐Induced Barrier Height Modulation
(2016)
Graphene–oxide–metal diodes are presented whose performance is preserved even for thin oxide layers, as required for high frequency applications. The diodes, which rely upon bias-induced modulation of graphene's work ...
I Simposio sobre Cambio Climático y Biodiversidad: Hacia el fortalecimiento de la resiliencia y acciones requeridas ante el Cambio Climático en Latinoamérica
I Symposium on Climate Change and Biodiversity: Towards strengthening the resilience and actions required to face Climate Change in Latin America
(2019)
El cambio climático es una variación significativa y permanente de los patrones globales del clima, sus consecuencias son irreversibles si no se toman las acciones pertinentes. En Latinoamérica, el cambio climático no ...
Pathological mutations in PNKP trigger defects in DNA single-strand break repair but not DNA double-strand break repair
(2020)
Hereditary mutations in polynucleotide kinasephosphatase
(PNKP) result in a spectrum of neurological
pathologies ranging from neurodevelopmental
dysfunction in microcephaly with early onset
seizures (MCSZ) to ...
Exploración del Everest en la zona mesofótica del Parque Nacional Isla del Coco
(2021)
Video realizado para difundir el proyecto 810-C1-081 "Estructura y biodiversidad de las comunidades de coral mesofóticas en el Parque Nacional Isla del Coco", que tiene como principal objetivo describir el monte Everest, ...
Hundreds of nuclear and plastid loci yield novel insights into orchid relationships
(2021)
PREMISE: The inference of evolutionary relationships in the species- rich family Orchidaceae has hitherto relied heavily on plastid DNA sequences and limited taxon sampling. Previous studies have provided a robust plastid ...
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 ...
