A supramolecular look at microenvironmental regulation of limbal epithelial stem cells and the differentiation of their progeny
(2017-07-01)
Various approaches have been taken to improve our knowledge of the microenvironmental regulation of limbal epithelial stem cells. Researchers have extensively investigated the roles of growth factors, survival factors, ...
Dynamics of confined liquid crystals
(Medellín - Minas - Doctorado en Ingeniería - Ciencia y Tecnología de MaterialesDepartamento de Materiales y MineralesUniversidad Nacional de Colombia - Sede Medellín, 2020-09-07)
Thermotropic nematic liquid crystals in contact with surfaces at the nanoscale were studied by means of beyond equilibrium thermodynamics and computational simulations. In particular, nanoparticles of different geometries ...
Chorismate synthase: An attractive target for drug development against orphan diseases
(2007-03-01)
The increase in incidence of infectious diseases worldwide, particularly in developing countries, is worrying. Each year, 14 million people are killed by infectious diseases, mainly HIV/AIDS, respiratory infections, malaria ...
Bloch surface waves in photonic crystal fibers
(Medellín - Ciencias - Doctorado en Ciencias - FísicaEscuela de físicaUniversidad Nacional de Colombia - Sede Medellín, 2019-09-13)
An electromagnetic surface wave (ESW) is a wave that travels at the interface between two media, and their fields decay exponentially on both sides of the boundary. ESWs are widely studied due to their potential applications ...
Structural and morphological characteristics of (Pb1-x Sr (x) )TiO3 powders obtained by polymeric precursor method
(Springer, 2010-01-01)
Pb1-x Sr (x) )TiO3 powders with different compositions (x = 0, 0.10, 0.50, 0.90 and 1) were synthesized by the polymeric precursor method and heat treated at 800 A degrees C for 2 h under air atmosphere. The thermogravimetric ...
Physicochemical characterization of drug nanocarriers
(2017-07-13)
Pharmaceutical design has enabled important advances in the prevention, treatment, and diagnosis of diseases. The use of nanotechnology to optimize the delivery of drugs and diagnostic molecules is increasingly receiving ...
Insights on Luminescent Micro- and Nanospheres of Infinite Coordination Polymers
(2022-01-10)
Coordination polymers have been extensively studied in recent years. Some of these materials can exhibit several properties such as permanent porosity, high surface area, thermostability and light emission, as well as open ...

(Universidade Federal de São CarlosUFSCarCâmpus São CarlosQuímica - Q, 2021-02-26)
Theoretical and experimental study of inorganic crystals is an interdisciplinary subject that have been attracting intense research and development due to both the fundamental and applied scientific value. Molybdates matrix ...
Phospholipase A(2) myotoxins from Bothrops snake venoms: Structure-function relationship
(Bentham Science Publ Ltd, 2004-11-01)
Phospholipases A(2) constitute the major components from Bothrops snake venoms and have been extensively investigated not only because they are relatively very abundant in these venoms but mainly because they display a ...
Precipitación de carbonatos inducida microbiológicamente como alternativa para remediar entornos naturales contaminados con metales y metaloides tóxicos
(Bogotá - Ciencias - Maestría en Ciencias - QuímicaDepartamento de QuímicaUniversidad Nacional de Colombia - Sede Bogotá, 2020-06-30)
This document shows in depth the scope and limitations of microbiologically induced calcium carbonate precipitation (MICP) in the remediation of environments contaminated with toxic metals (e.g.: Cd, Cr and Pb) and metalloids ...
