A highly sensitive electrochemical biosensor for the detection of trace amounts of methotrexate has been designed. Double stranded (ds)DNA molecules are immobilized onto a pretreated glassy carbon electrode (GCE(ox)) surface with Langmuir–Blodgett (LB) technique. The adsorptive voltammetric behaviors of methotrexate on DNA-modified electrode were explored by means of cyclic voltammetry (CV) and square...
The influences of statically deformed state including both the elastic and plastic deformations induced by applied uniaxial stresses on the Love waves in layered rocks are investigated on the basis of the acoustoelastic theory for elastic-plastic materials. The phase velocity equations of the Love waves are obtained by direct boundary conditions. The acoustoelastic effects of elastic and elastic-plastic...
A fundamental issue in wireless sensor network is to extend network lifetime while maintaining network coverage and connectivity. Protection for sensors themselves is another important concern. An energy-aware coverage based node scheduling scheme (ECNS) is proposed to provide protection for sensors and guarantees network connectivity and desired coverage level. ECNS enables each node to decide whether...
Eight lanthanide complexes of the type [LnB 2 Cl 3 ] nH 2 O (Ln = La, Pr, Sm, Tb, Ho, n = 2; Eu, n = 1; Nd, n = 4; Dy, n = 3; and B = benzoin) have been synthesized and characterized by chemical analysis, molar conductance, IR, electronic, resonance Raman, fluorescence, 1 H NMR and X-ray photoelectron spectroscopies and TG-DTA analysis.
