Cultivo in vitro de Geophila macropoda (Ruiz & Pav.DC) a partir de embriones cigóticos
In vitro culture of Geophila macropoda (Ruiz & Pav. DC) from zygotic embryos. The goal of this research was to develop a protocol for the in vitro culture of Geophila macropoda. The work was conducted in Guácimo, Limón, ...
Micropropagación de Pilón (Hieronyma Alchorneoides)
Micropropagation of pilon (Hieronyma alchorneoides). Pilon (Hieronyma alchorneoides) (Euphorbiaceae) is one of the native timber species of Costa Rica best adapted to conditions of open plantation. Due to its growth ...
Gated supramolecular chemistry in hybrid mesoporous silica nanoarchitectures: controlled delivery and molecular transport in response to chemical, physical and biological stimuli
(Royal Society Of Chemistry, 2015-05)
This review presents and discusses recent advances in the emerging field of "gated nanochemistry", outlining the substantial progress made so far. The development of hybrid mesoporous silica with complex tailored pore ...
Crossing biological barriers with nanogels to improve drug delivery performance
(Elsevier Science, 2019-08)
The current limitations in the use of nanocarriers to treat constantly evolving diseases call for the design of novel and smarter drug delivery systems (DDS). Nanogels (NGs) are three-dimensional crosslinked polymers with ...

Nature-Inspired Protecto-Flexible Impact-Tolerant Materials
(Wiley-VCH Verlag, 2020-01-01)
The search for impact-tolerant, light-weight flexible materials has challenged materials scientists and engineers for decades. In this quest, many researchers have focused on studying natural armor as a guide to propose ...
Interaction with water in nature and self-cleaning potential of biological materials and species
(Facultad de Diseño y Comunicación. Universidad de Palermo, 2020)
Structural shape optimisation using boundary elements and the biological growth method
A numerical evolutionary procedure for the structural optimisation for stress reduction of two-dimensional structures is presented in this paper. The proposed procedure couples the biological growth method (BGM) with the ...
Biodistribution of titanium dioxide from biologic compartments
The layer of titanium dioxide (TiO2) of the implant is chronically exposed to the internal electrolyte milieu in the peri-implant biological compartment. Corrosion results from electrochemical attack and ensuing gradual ...
