Tracking dipeptides at work-uptake and intracellular fate in CHO culture
(AMB Express, 2016)
Market demands for monoclonal antibodies (mAbs) are steadily increasing worldwide. As a result, production processes using Chinese hamster ovary cells (CHO) are in the focus of ongoing intensification studies for maximizing ...
Assessing soil water repellency of a sandy field with visible near infrared spectroscopy
(Scopus, 2015)
Soil water repellency (WR) is a widespread phenomenon caused by aggregated organic matter (OM) and layers of hydrophobic organic
substances coating the surface of soil particles. These substances have a very low surface ...
Synthesis, properties, and two-dimensional adsorption characteristics of 5-amino[6]hexahelicene
(Willy, 2016)
A convergent synthesis of racemic 5-amino[6]hexahelicene
is described. Cross-coupling reactions are used to
assemble a pentacyclic framework, and a metal-catalyzed
ring-closure comprises the final step. The enantiomers ...
Effect of pretreatment temperature on the surface modification of diatomite with trimethylchlorosilane
(Journal of Porous Materials, 2016)
Diatomite samples from Costa Rica were purified
using acidic treatments with hydrochloric acid, thermally
treated (400–1000 C) and then silylated with
trimethylchlorosilane in toluene under inert atmosphere.
The ...
Comparative study of the optical behavior of a porphyrin encapsulated in sol-gel silica coatings and in solution as a function of pH
(Elsevier, 2016)
We report a comparative optical spectral study as a function of pH on a porphyrin encapsulated in a solgel
matrix and in methanol solution. Its response has been discussed in terms of pH-sensitivity as a
function of the ...
Site-specific cleavage of ribosomal RNA in Escherichia coli-based cell-free protein synthesis systems
(PLoS ONE, 2016)
Cell-free protein synthesis, which mimics the biological protein production system, allows
rapid expression of proteins without the need to maintain a viable cell. Nevertheless, cellfree
protein expression relies on ...
Inventarios de gases de efecto invernadero de las escuelas primarias de Belén, Heredia, Costa Rica Greenhouse gases produced by primary schools in Belén, Heredia, Costa Rica
(Cuadernos de Investigación UNED, 2015)
There is no published information on
greenhouse gas emision in public schools of Costa Rica. Using as reference
the national voluntary standard INTE / ISO 12-01-06: 2011 I measured
emissions in three primary schools: ...
