Efficient counter electrode for quantum dot sensitized solar cells using p-type PbS@reduced graphene oxide composite.

This study developed a novel PbS-rGO composite counter electrode to enhance the performance of quantum dot-sensitized solar cells (QDSSCs). The composite was synthesized a hydrothermal method by anchoring PbS nanocubes onto reduced graphene oxide (rGO) sheets. The effect of the mass ratio of rGO to PbS (0.

Optimizing pterygoid implant placement without sinus intrusion in edentulous vietnamese patients: A comprehensive tomographic analysis and cross-sectional study.

Background: Severe maxillary resorption presents challenges in dental implant placement. This research aims to assess the feasibility, angular orientation, and appropriate length of pterygoid implants in patients with significant maxillary atrophy.

Material And Methods: The study examined Cone Beam Computed Tomography (CBCT) scans from 60 completely edentulous patients classified as Cawood and Howell's Classes V or VI, with less than 4mm residual bone height in their posterior maxilla.

Novel mixed nickel/cobalt hexacyanoferrate microcubes with synergistic effects for aqueous hybrid supercapacitors.

Combining different metals in coordination compounds is an efficient strategy to improve their various properties. Herein, mixed nickel-cobalt hexacyanoferrate (NiCoHCF) microcubes of varying  :  molar ratios are synthesized a co-precipitation route and comprehensively characterized to study their material and electrochemical properties. NiCoHCF microcubes display the battery-type electrochemical energy storage mechanism in aqueous electrolytes.
