Three benzimidazole-based organic dyes, possessing the same triphenylamine donors and cyanoacrylic acid acceptors with the bithiophene π-bridges combined in different nuclear positions of benzimidazole, were investigated in the utility of dye-sensitizer solar cells. The structure, molecular orbital and energy, absorption spectra and some important parameters (such as light harvesting efficiency...

<p>Fabrikasi DSSC dengan menggunakan sensitizer zat warna sintetik yang mahal dan susah diperoleh dapat diatasi memanfaatkan alami dari limbah biomassa kulit bawang merah. Penelitian tentang ekstraksi antosianin merah <em>(Allium cepa)</em> pemanfaatannya sebagai pemeka (<em>sensitizer</em>) pada <em>Dye Sensitized Solar Cell</em> (DSSC) telah dilakukan...

Objective(s): Low penetration depth of light is the main defect of photodynamic therapy (PDT), which could be improved by sonodynamic therapy (SDT). In this study, a combination of PDT and SDT known as sonophotodynamic therapy (SPDT) was investigated using two reverse arrangements in CT26 tumor model. Materials and Methods: The liposomal zinc phthalocyanine was synthesized and characterized. It...

Objective(s) Sonodynamic therapy is a physical treatment which utilizes ultrasound waves with an appropriate sensitizer such as protoporphyrin IX (PpIX). The activation of sensitizer depends on cavitation, and therefore, high intensity ultrasound is an important necessity. Beside, high intensity ultrasound can induce side effects on the healthy tissues which have surrounded tumor. The particle...
