Activation of Nrf2 by lead sulfide nanoparticles induces impairment of learning and memory

This study aimed to determine, using rats, the mechanism of action of PbS NPs, exposure to which results in persistent alterations in nervous system function. The results showed that PbS NPs significantly impaired learning and memory.

Особенности транспорта электронов и фотопроводимости в слое наноразмерных частиц сульфида свинца

In the lead sulfide nanoparticles-based layers deposited from alcohol suspensions, analysis of the current-voltage characteristics made it possible to establish the basic mechanism of electron transport. Previously, using optical measurements in the range of 3500 nm, it was shown that the organic component in such layers was practically absent. When exposed to wide range radiation corresponding to the “transparency window” of the atmosphere of 8000–14000 nm, a current change in PbS nanodust was detected, where, as previously shown, absorption on free charge carriers can occur.
