2D Hierarchical NiMoO Nanosheets/Activated Carbon Nanocomposites for High Performance Supercapacitors: The Effect of Nickel to Molybdenum Ratios.

Supercapacitors have the potential to be used in a variety of fields, including electric vehicles, and a lot of research is focused on unique electrode materials to enhance capacitance and stability. Herein, we prepared nickel molybdate/activated carbon (AC) nanocomposites using a facile impregnation method that preserved the carbon surface area. In order to study how the nickel-to-molybdenum ratio affects the efficiency of the electrode, different ratios between Ni-Mo were prepared and tested as supercapacitor electrodes, namely in the following ratios: 1:1, 1:2, 1:3, 1:4, and 1:5.

The impact of diabetes mellitus on health-related quality of life in Saudi Arabia.

Objective: To evaluate the effect of different demographic, clinical and social factors on diabetic patients' quality of life (QOL).

Research Design And Methods: A cross sectional study conducted on patients with type 2 diabetes who attended King Abdulaziz University Hospital outpatient clinics between February and March 2017. The patients were asked about sociodemographic data including age, sex, educational level, exercise history and marital status in addition to clinical data such as duration of diabetes, presence of comorbidities as well as medication history.
