ZnCoO/g-CN/Cu nanocomposite as a new efficient and recyclable heterogeneous photocatalyst with enhanced photocatalytic activity towards the metronidazole degradation under the solar light irradiation.

In this study, ZnCoO/g-CN/Cu is synthesized as a new and highly effectual solar light-driven heterogeneous photocatalyst. The prepared photocatalyst is characterized using FT-IR, XRD, XPS, DRS, FESEM, TEM, EDS, and elemental mapping techniques. The performance of ZnCoO/g-CN/Cu is studied towards the metronidazole (MNZ) degradation under solar light irradiation.

Frequency of latent and smear positive tuberculosis in chronic psychotic disorders.

Objective: Screening is one of the ways to combat Tuberculosis (TB) and should be mostly concentrated on groups showing some symptoms of the disease. Tuberculosis can be transferred from person to person in laboratories, prisons and psychiatry hospitals. The purpose of this study was to survey pulmonary TB in patients with schizophrenia in Rasht.
