Abstract:
... Realization of photo-electrochemical water splitting to generate H₂ alternative fuel requires the facilitation of the kinetically-sluggish oxygen evolution reaction (OER) occurring at the photoanode. To do so, there is a need to develop new methods to assemble suitable OER co-catalysts at the semiconductor–solution interface. Although Metal–Organic Frameworks (MOFs) are frequently used as precurso ...

Abstract:
... Photo-active metal–organic frameworks (MOFs) are considered as promising materials for the study of photo-electrochemical cells (PECs). They can be utilized as porous, high surface area scaffolds for the assembly of molecular chromophores atop semiconducting electrodes. Usually, however, the lack of prominent electronic interactions between adjacent MOF-installed chromophores impedes the developme ...

Abstract:
... The impact of addition of palmitic acid (PA) on the amylose‐lipid complexes formation and their influence on amylopectin retrogradation were studied. Tortillas prepared with 0.0%, 1.0% and 1.5% (w/w) of PA were stored for 0, 7, and 14 days at 4 °C. Tortillas with 1.0% and 1.5% of PA were softer than tortillas without PA during storage time; this change can be associated with reduction in starch re ...

Abstract:
... Quality problems observed at certain times of year, related to low soluble solids content (°Brix), have restricted the exportation market and, thus, the expansion of papaya cultivation in the Canary Islands. In order to develop new management strategies oriented to maintain a steady marketable fruit supply all year around, it is necessary to improve our knowledge of crop phenology under the specif ...
