Macromolecular and functional properties of galactomannan from mesquite seed (Prosopis glandulosa).

Abstract: In this work, galactomannans from Prosopis glandulosa seeds were evaluated for their chemical composition and functional properties for potential industrial applications. In addition, those characteristics were compared with the commercial galactomannan guar gum. Mannose and…

Enhancing the Mechanical Performance of Bleached Hemp Fibers Reinforced Polyamide 6 Composites: A Competitive Alternative to Commodity Composites.

Rosa Idalia Narro-Céspedes Abstract: Automotive and industrial design companies have profusely used commodity materials like glass fiber-reinforced polypropylene. These materials show advantageous ratios between cost and mechanical properties, but poor environmental yields. Natural fibers have been…

Synthesis and phase evolution of a glass-ceramicbiomaterial with near-eutectic composition of thepseudo-binary system diopside–tricalciumphosphate.

Claudia Magdalena López-Badillo A glass-ceramic biomaterial with near-eutectic composition of the pseudo-binary systemdiopside (CMS2, CaMgSi2O6)–tricalcium phosphate [C3P, Ca3(PO4)2], with a weight compo-sition of 61% CMS2–39% C3P, was synthesized by the so-called “petrurgic method”. Threedifferent cooling rates…

IMPROVED NITRIDING CAPABILITY OF NONALLOYED STEELS ASSISTED WITH ACTIVE SCREEN PLASMA TREATMENT.

Claudia M. Lopez-Badillo The nonalloyed steels are very cost-e®ective, but their usefulness in numerous applications is imbedded due to low mechanical strength. The strength of several steels can be improved by nitriding; however, nonalloyed steels are…

Goethite–titania composite: disinfection mechanism under UV and visible light†.

Claudia M. Lopez-Badillo Goethite–titania (a-FeOOH–TiO2) composites were prepared by co-precipitation and mechanical milling. The structural, morphological and optical properties of as-synthesized composites were characterized by X-ray powder diffraction, scanning electron microscopy and UV-Vis diffuse reflectance spectroscopy,…
