Three-dimensional BiO/Ti microspheres as an advanced negative electrode for hybrid supercapacitors.

Herein, we report a novel, low-temperature solvothermal method to grow 3D-Bi2O3 flower-like microspheres on Ti substrates as a binder-free negative electrode for supercapacitor applications. The Bi2O3/Ti electrode showed an areal capacitance of 1.65 F cm-2 at 4 mA cm-2.

Nano-CeO2 decorated graphene based chitosan nanocomposites as enzymatic biosensing platform: fabrication and cellular biocompatibility assessment.

The present study summarizes the designing of a green transducer phase based on nano-cerium oxide (CeO2) decorated reduced graphene oxide (RGO) reinforced chitosan nanocomposites as an effective enzyme immobilizer and bio-sensing matrix for glucose analyte. Also, it scrutinizes the biocompatibility and cell viability of the synthesized nanohybrid with human fibroblastic macrophage cell line. CeO2 nanoparticles (NPs) were successfully grown on graphene nanosheet in the presence of cationic surfactant followed by facile hydrothermal treatment.

Cross-sectional analysis of psychological aspects of adolescent underachievers.

Background: Previous research supports that factors commonly associated with underachievement include low academic self-concept, low self-efficacy, low self-motivation, low goal valuation and negative attitude toward school and teachers.

Purpose: The purpose of this study was to assess the feeling about reading of adolescent underachievers, including emotional difficulties, physical problem (usually eye dysfunction), mechanism of reading, self-concept, and interest in reading.

Materials And Methods: Forty-eight underachievers were compared with 40 achievers from 6 to 10 standard students on "My feeling about reading" checklist.
