Nanostructured hydrogels of acrylamide and determining their ability to absorb water and ethanol [Hidrogeles microestructurados de acrilamida y determinación de su capacidad de absorber agua y etanol]
(2013)
This paper reports the synthesis of nanostructured hydrogels of acrylamide by a two-step polymerisation process. The first step is performed by inverse microemulsion polymerization (water-in-oil) of N-isopropylacrylamide ...

Heat loss of a trapezoidal cavity absorber for a linear Fresnel reflecting solar concentrator
(Pergamon-Elsevier Science Ltd, 2012-03)
The present paper studies the heat loss of a linear absorber with a trapezoidal cavity and a set of pipes used for a linear Fresnel reflecting solar concentrator. The study includes the measurements on a 1.4 m long prototype ...
