In this paper, a nonenzymatic glucose biosensor based on perovskite LaTiO3-Ag0.2(LTA) modified electrode was presented. The morphology and the composition of the perovskite LaTiO₃-Ag0.2 nanomaterials were characterized by using scanning electron microscopy (SEM) and X-ray diffraction (XRD) respectively. The LaTiO₃-Ag0.2(LTA)

Targeted radiotherapies maximize cytotoxicty to cancer cells. In vivo α-generator targeted radiotherapies can deliver multiple α particles to a receptor site dramatically amplifying the radiation dose delivered to the target. The major challenge with α-generator radiotherapies is that traditional chelating

Phoslock(®) is increasingly used worldwide to control sediment phosphorus (P) release and cyanobacterial blooms despite the fact that little is known about its mode of action in lake bed sediments. This study quantified the effects of Phoslock(®) on sediment elemental

The lattice dynamics of La(1/2)Na(1/2)TiO(3) single crystal have been investigated by far-infrared and Raman scattering spectroscopy. Far-IR reflectivity spectra revealed Slater, Last and Axe modes near 140, 190 and 555 cm(-1), respectively. The frequency of the Slater mode decreases by about
