Ludzik, D.S. NeovAbstractWater confined in nanoscale exhibits unique structural properties compared to the bulk phase. The effects of confinement of water in carbon nanopores were investigated in this study using differential scanning calorimetry (DSC), dielectric spectroscopy (DS), and neutron diffraction (ND). The ice was confined in slit-shaped pores of activated carbon fibers (ACF) and cylindrical-shaped porous system (ordere...

In this study, we report a simple method to synthesize a novel green nanocatalyst using titanium dioxide, graphene and Citrus sinensis peel extract using a low-power CO2 laser fabrication. The relevance of the resulting nanomaterial (Lp-TiO2/G-nCSP) for the photocatalytic degradation of reactive red-45 (RR-45) was studied exhaustively. Compared to the commercial TiO2 photocatalyst, the green synthesized and laser-fabricated nanocatalyst exhibited better UV-light irradiated photocatalytic activity for RR-45 degradation. The laser fabricated nanocatalyst was systematically characterized by scanning electron microscope (SEM),...

SalehAbstractThe removal of cetylpyridinium chloride (CPC) (as a cationic surfactant) on nanoporous nickel phosphate (nano-NiPOx) particles is studied for the first time. The structure and morphology of the material are investigated using X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDAX), transmission electron microscopy (TEM) and BET surface area determination. Various operating parameters, such as the initial CPC concentration, ...

In this study, we investigated the occurrence of xyloglucan and cellulose in pea border cells and mucilage using cytochemical staining, immunocytochemistry and laser scanning confocal microscopy. Our data show that i) unlike cellulose, xyloglucan is highly present in the released mucilage as a dense fibrillary network enclosing border cells and ii) that xyloglucan and cellulose form molecular cross-bridges that tether cells and maintain them attached together. These findings suggest that secreted xyloglucan is essential for mucilage strengthening and border cell attachment and functioning.

It is commercially available as a bio-pesticide targeting a wide variety of pests. The present study was intended to evaluate the biochemical interactions of karanjin with bovine serum albumin (BSA) and study its toxicological effects on mammalian and bacterial cell lines. Karanjin bound to BSA at a single site with a ...

VarelaAbstractThe effect of the nitrate salt addition on the liquid range of the protic ionic liquid ethylammonium nitrate (EAN) was studied in this work. The salts used were monovalent, LiNO3; divalent, Mg(NO3)2 and Ca(NO3)2, and trivalent, Al(NO3)3; inorganic salts containing metals relevant for electrochemical applications. Solid-liquid transitions, which define the lower limit of the liquid range of the fluids, were determined using differe...
