Research ArticleOpen accessIn the abstractApplication of Titanium Dioxide Self-Cleaning Coatings on Photovoltaic Modules for Soiling Related Losses ReductionAnnalisa Andaloro, Francesco FrontiniSeveral studies have assessed the influence of soiling deposition on Photovoltaic (PV) modules front-cover with regards to performance losses over time. In fact, soiling phenomena in PV systems are ascribed as responsible for medium and long-term yield reduction up to 16% over the first-year of outdoor exposure. Provided that PV technology is a low yield energy production source, maintaining module … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 1 · 5 Feb 2017 · 7,670 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSynthesis of Graphene Oxide via Liquid Exfoliation Using Self-Custom-Made Tweeter Piezoelectric Ultrasound Generator and Assisted by Surfactant from Commercial DetergentAchmad Ainul Fikri, Aminah Nur Aisyah, Suhufa Alfarisa, Wipsar Sunu Brams DwandaruRapid progress in nanotechnology requires the production of novel nanomaterials. This study aims to synthesize Graphene Oxide (GO) via the Liquid Exfoliation (LE) method using a self-custom-made tweeter piezoelectric system as the ultrasound generator.
