Green microwave synthesis of ZnO and CeO nanorods for infectious diseases control and biomedical applications.

Control of Infectious diseases such as; bacteria and viruses, has become a globally critical issue, since the appearance of COVID-19 virus in 2020. In addition to the microbial resistance of the currently available therapeutic drugs as well as, its prolonged side effects make its use is of health care concern. Green nanotechnology approach is a promising solution for controlling such infectious diseases and many biomedical purposes.

Simple and Fast Microwave-Assisted Synthesis Methods of Nanocrystalline TiO and rGO Materials for Low-Cost Metal-Free DSSC Applications.

Nanocrystalline TiO and reduced graphene oxide (rGO) materials have been synthesized by a simple and low-cost microwave-assisted hydrothermal method and applied in dye-sensitized solar cells (DSSCs) as photoactive and metal-free counter electrodes, respectively. Different TiO nanocrystalline materials have been synthesized via the acid hydrolysis sol-gel method, followed by microwave hydrothermal treatment at 210 °C and 300 psi and at different microwave irradiation times (20, 30, 45, and 60 min) instead of the usual hydrothermal time of 12 h. The properties of the produced mesoporous nanocrystalline TiO are investigated in terms of their morphology, crystal structure, optical properties, and surface area behavior using relevant characterization techniques.

Synthesis, characterization and color performance of novel Co²+-doped alumina/titania nanoceramic pigments.

Blue-green nanoceramic pigments from Co(2+)-doped alumina-titania (xCo(2+)-Al(2)O(3)/TiO(2)) have been synthesized by alkoxide sol-gel route from a mixture of titania and boehmite sols that derived from titanium isopropoxide and aluminum nitrate precursors. The composition of the alumina/titania (AT) matrix is 3:1M ratio. A series of xCo(2+):3TiO(2):1Al(2)O(3) mixed oxides with different Co(2+)-dopant ion concentration has been prepared.

Effect of general and epidural anesthesia on hemostasis and fibrinolysis in hepatic patients.

This study was designed to compare the effect of general anesthesia using isoflurane and epidural anesthesia using ropivacaine on hemostasis in hepatic patients. Sixty patients were randomly allocated into two groups to receive either general or epidural anesthesia which further subdivided into control and hepatic subgroups. Blood samples were collected preoperatively, immediate post-operatively and on third post-operative day to measure hemoglobin (Hb), platelet count (PLT),), prothrombin time (PT), partial thromboplastin time (PTT), and thrombin time (TT).

Enhancing the photoelectrical performance of dye-sensitized solar cells using TiO2:Eu3+ nanorods.

TiO(2):Eu(3+) nanorods are hydrothermally grown and used to fabricate a bilayer film electrode in a dye-sensitized solar cell. A light-to-electrical energy conversion efficiency of 8.0% and a quantum efficiency of 93.

High efficiency dye-sensitized solar cell based on novel TiO2 nanorod/nanoparticle bilayer electrode.

High light-to-energy conversion efficiency was achieved by applying novel TiO2 nanorod/nanoparticle (NR/NP) bilayer electrode in the N719 dye-sensitized solar cells. The short-circuit current density (J SC), the open-circuit voltage (V OC), the fill factor (FF), and the overall efficiency (η) were 14.45 mA/cm(2), 0.
