    This research was aimed to examine conditions on synthesis of nanoporous carbon materials from durian peel via the process of hydrothermal carbonization (HTC) as an application for delaying durian ripening process. The experiment was conducted by using durian peel as materials for producing nanoporous carbon via the process of hydrothermal at 160-200 C for 8-24 hours. It also included the process of carbonization at 500-900 C for 2 hours under nitrogen atmosphere for developing pore structure and removing contaminants to obtain the nanoporous carbon. The properties of nanoporous carbon were characterized by scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FT-IR) and Raman spectrometer analysis. The results indicated that the process of hydrothermal at 200 C for 12 hours and carbonization at 900 C for 2 hours was suitable for delaying ripe durian. This is become of the carbon content, porous structure and amorphous structure increased with HTC temperature.

    The electrical and optical properties of organic-inorganic hybrid light emitting diodes (HLED) have been investigated. The HLED is consisted of organic material N,N'-di(naphthalene-1-yl)-N,N'- diphenyl-benzidine (NPB) as a hole transport layer and inorganic material zinc selenide (ZnSe) as an electron transport layer and emitting layer as well. The electrical and optical properties have been characterized by current-voltage measurement and electroluminescence (EL) spectroscopy, respectively. The current of HLED decreases with increasing ZnSc thickness, while the threshold voltage increases. The EL spectrum exhibits two peaks at 457 nm and 500 nm, due to electron-hole recombination from energy gap of ZnSe and recombination from defect states in ZnSe layer, respectively. The emission mechanism is described by electric field in organic and inorganic layers. © 2007 IEEE.
