Zn-doped titania nanoparticles as building blocks for solid foam filters of water and air via photocatalytic oxidation
Photocatalytic oxidation (PCO) could provide energy-efficient purification of water and air. Its efficacy is constrained mainly by limited photocatalytic activity and active surface. To address both, solid foams with hierarchic porous structures spanning multiple length-scales, stabilized by photocatalytic Zn-doped titania nanoparticles (NP) were synthesized and tested. The NP were characterized by SEM, EDS, DLS, XRD, Raman and UV–Vis spectroscopies. Solid foams were stabilized by NP complexes with cationic surfactants. The foam morphology was characterized and photocatalytic activity was demonstrated in water. The present work paves the way for the development of efficient systems for air and water purification in demanding technological sectors, such as aerospace
Biochemical and PMF MALDI-TOF analyses of two novel papain-like plant proteinases
Two cysteine endopeptidases from latex of Araujia angustifolia (araujiain aI and araujiain aIII) were purified and characterized by means of conventional and proteomics techniques (MALDI-TOF). N-terminal sequences showed a high percentage of identity with cysteine proteinases belonging to the papain family. The peptide mass fingerprint analysis demonstrated a close homology among both proteinases.Centro de Investigación de Proteínas Vegetale
