To advance the photodetection capabilities of type II core/shell nanowire‐based photodetectors, ZnSe has been employed to coat on ZnO nanowire array creating a type‐II heterojunction core/shell nanowire array with additional lower indirect band gap (≈1.84 eV), via a facile two‐step process of chemical vapor deposition and pulse laser ablation. The integrated photodetector based on the ZnO/ZnSe core/shell structure is capable of detecting the entire range of the visible spectrum, from blue to red excitation source, as well as UV light. The absolute sensitivity and the percentage change in responsivity of the photodetector are enhanced by one and three orders of magnitude, respectively. The whole range visible light photodetection and enhanced photocurrent response are attributed to the unique ZnO/ZnSe energy band realignment and the piezophototronic effect. Moreover, the photodetector exhibits self‐powered photodetection behavior under UV/visible light illumination. This study grants a potential application using ZnO/ZnSe type II heterostructure core/shell nanowire array for broad band UV/visible photodetection in both powered and self‐powered circumstances.

Objective: To investigate the association between the parental education and occupation and their effects on childhood obesity. Methods: This cross-sectional retrospective study was conducted in Jeddah, Saudi Arabia in 2017. The data were collected from children and adolescents aged 2-18 years old. The participants were directed to an ambulatory clinic in King Abdul-Aziz Hospital for executing anthropometric measurements. Results: Of the total 328 participants 170 were male children and 158 were female children. The prevalence rates of overweight, obese and severely obese children were 139, 160 and 29 respectively. It is identified in this study that those children were more to be obese if they had employed fathers (93.3%) with pvalue= (0.031) and non-working mothers (55.7%) with p-value= (0.047). It is identified that there was no significant relation between BMI categories and father's education level (P-value= 0.226, ρ = 0.059) and mother's education (P-value= 0.291, ρ = 0.052). Conclusion: Overweight and obesity among children living in Jeddah, Saudi Arabia is not associated with the educational levels of both parents, however, it is also identified that overweight and obesity were associated with employed father and non-employed mothers.
