in this article, hybrid organic-inorganic materials were prepared by free radical copolymerization of 2-hydroxyethyl methacrylate (hema) and 3-methacryloxy-propyltrimethoxysilane (mptms) via sol-gel process. the methoxysilane-containing copolymer precursors were synthesized at different compositions. these copolymer precursors were then hydrolyzed and condensed to produce phema-sio2 nanocomposi...

The POM-based inorganic–organic hybrids with different structures were assembled and used as the friction materials to construct TENGs results demonstrated that output performance was closely related dielectric constant.

The construction of well-defined organic architectures on solid surfaces is a key step toward the development of more efficient and robust electronic devices. Indeed, a number of self-assembly strategies have been applied to building supramolecular structures for use in devices such as organic lightemitting diodes (OLEDs), organic transistors, and solar cells. Recently, self-assembled coordinat...

Introduction Advances in microelectronic materials and processing techniques have pushed device sizes much smaller than micrometer dimensions. Hence, the new realm of electronic devices can be more accurately described as nanoelectronics. Phenomenon in thin film organic materials is now being used to create operational devices with active elements approaching single molecule dimensions. We have...

we investigated the distribution of asbestos containing materials(acms) in korea for 15 school buildings built before and after 1990, including elementary schools, middle schools and high schools. in order to perform risk assessments of samples gathered from the buildings, the study used four different rules as the criteria: results from the ahera rule, the hse rule and the astm rule on acms we...

Several photocatalytic nanoparticles are synthesized and studied for potential application for the degradation of organic and biological wastes. Although these materials degrade organic compounds by advance oxidation process, the exact mechanisms of microbial decontamination remains partially known. Understanding the real mechanisms of these materials for microbial cell death and growth inhibit...
