The dehydration of fructose and glucose to 5-hydroxymethylfurfural was studied using LaOCl/Nb2O5 in hot compressed water conditions. The catalysts were prepared by impregnation of LaCl3 on Nb2O5 with different loadings. The solids were characterized by EDX, XRD, TGA and N2 physisorption at 77 K and pyridine and CO2 adsorption followed by FTIR; the strength of acidity and basicity was determined by...
This paper presents an embedded system for access control in restricted area through the integration of two authentication strategies: facial recognition and RFID TAGs. Once face recognition, in an embedded system, is susceptible to failures, the integration with RFID tags aims to increase the robustness of access control system. This system can be easily deployed into enterprise environments, meetings...
