A new procedure is described for the determination of Hg2+ ions in water samples. Rhodamine based fluorescent sensor was synthesized and experimental conditions were specifically optimized application to environmental samples, which requires low detection limits high selectivity competitive experiments with realistic concentrations other metal ions. Incorporation a Rhodamine-6G fluorophore prev...

A finite element model is proposed permitting prediction of elastic wave bandgaps periodic composite microplates incorporating flexoelectric effect. In this model, we applied curvature-based flexoelectricity and Mindlin plate theories derived a formulation that has been implemented for bandgap analysis. The utilizes three-node triangle with 30 degrees freedom satisfying kinematics assumptions. ...

In this work, a new displacement-based Trefftz plate element is developed for size-dependent bending analysis of the thin structures in context modified couple stress theory. This achieved via two steps. First, functions, that are derived by introducing assumptions into three-dimensional governing equations elasticity, adopted as basis functions designing element's displacement interpolations. ...
