The United Arab Emirates is moving towards the use of renewable energy for many reasons, including country’s high consumption, unstable oil prices, and increasing carbon dioxide emissions. usage electric vehicles can improve public health reduce emissions that contribute to climate change. Thus, resources meet demands major challenge influencing development an optimal smart system satisfy requirements, enhance sustainability negative environmental impacts. objective this study was examine...
Together, advanced technologies and metallic materials rapidly progress in the field of Laser Powder Bed Fusion (PBF-LB) additive manufacturing (AM). Although PBF-LB drastically shortens design-to-manufacture time, post-processing operations on metal parts, including heat-treatments, are often labour intensive time-consuming. Therefore, we assess feasibility conductingin-situ heat-treatments during AlSi10Mg parts. A build plate heated at set temperatures up to 500 °C was employed while...
This paper presents a facile and economic development of dye-sensitized solar cells using nonprecious counter electrode made from ball-milled tellurium-doped graphene (Te-Gr) natural sensitizer extracted Calotropis gigantea leaves. The prepared materials were characterized various techniques, such as Raman spectroscopy, X-ray diffraction (XRD), atomic force microscopy (AFM), impedance scanning electron with built-in energy-dispersive spectroscopy (SEM EDS). electrochemical activity the...
The United Arab Emirates (UAE) enjoys abundant solar radiation with high ambient temperature. A operating temperature for photovoltaics is therefore expected in this region. applications of the third generation dye-sensitized cells (DSSCs) are currently hindered by production costs associated synthetic ruthenium-based dyes. Furthermore, performance most DSSCs considerably drops at elevated cell which disadvantageous to Natural dyes extracted from native desert plants UAE offers a potentially...

Laser powder bed fusion (L-PBF) additive manufacturing has reached wide-scale technology readiness for various sectors. However, some challenges posed by the complex nature of process persist. Limited studies investigated correlation between micro- and macroscopic properties L-PBF AlSi10Mg parts features’ sizes with build orientation in mind. Therefore, this study presents a comprehensive view on “size effect” samples larger than those available literature (up to 12 mm) defects,...
The purpose of this pilot study is to assess the United Arab Emirates dentists' preparedness manage medical emergencies. Ninety-seven licensed dentists participated in study. Dentists responded self-administrated questionnaires that contained 23 questions divided into five parts. first part collected data on participants' sex, years experience, and whether they are general dental practitioner (GDP) or specialists. second included seven asked participants indicate if took history, obtained...
