Morphological modifications and surface amorphization in ZnO sonochemically treated nanoparticles
(2013-05-01)
Application of nanoscale materials in photovoltaic and photocatalysis devices and photosensors are dramatically affected by surface morphology of nanoparticles, which plays a fundamental role in the understanding of the ...
The interaction of bothropstoxin-I (Lys49-PLA(2)) with liposome membranes
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
Bothropstoxin-I (BthTx-I) is a Lys49-PLA(2) from the venom of the snake Bothrops jararacussu, which permeabilizes biological and artificial membranes by a mechanism independent of lipid hydrolysis. This mechanism has been ...
Synthesis, characterization and spectroscopy of the europium doped lanthanum trimetaphosphate
(1998-07-24)
Orthorhombic modification of europium doped lanthanum trimetaphosphate has been prepared. The compound was obtained by precipitation of rare earth chloride solution with trimetaphosphoric acid. The characterizations were ...

Modified woodflour as thermoset fillers Part I. Effect of the chemical modification and percentage of filler on the mechanical properties
(Elsevier, 2001-12)
Composites made from an unsaturated polyester/styrene thermoset matrix and esterified woodflour have been prepared and tested. Different degrees of esterification of the wood particles with maleic anhydride were obtained ...
Sulfated xylomannans from the red seaweed Sebdenia polydactyla: Structural features, chemical modification and antiviral activity
(International Medical Press, 2009-04)
Background: Many viruses display affinity for cell surface heparan sulfate proteoglycans with biological relevance in virus entry. This raises the possibility of the application of sulfated polysaccharides in antiviral ...
