Abstract. Zinc oxide (ZnO) is an important material for hybrid inorganic−organic devices in which the characteristics of the interface can dominate both the structural and electronic properties of the system. These characteristics can be modified through chemical functionalization of the ZnO surface. One of the possible strategies involves covalent bonding of the modifier using silane chemistry. Whereas a significant body of work has been published regarding silane attachments to glass and SiO2, there is less information about the efficacy of this method for controlling the surface of metal oxides. Here we report our investigation of molecular layers attached to polycrystalline ZnO through silane bonding, controlled by an amine catalyst. The catalyst enables us to use triethoxysilane precursors and thereby avoid undesirable multilayer formation. The polycrystalline surface is a practical material, grown by sol−gel processing, that is under active exploration for device applications. Our study included terminations with alkyl and phenyl groups. We used water contact angles, infrared spectroscopy, and X-ray photoemission spectroscopy to evaluate the modified surfaces. Alkyltriethoxysilane functionalization of ZnO produced molecular layers with submonolayer coverage and evidence of disorder. Nevertheless, a very stable hydrophobic surface with contact angles approaching 106° resulted. Phenyltriethoxysilane was found to deposit in a similar manner. The resulting surface, however, exhibited significantly different wetting as a result of the nature of the end group. Molecular layers of this type, with a variety of surface terminations that use the same molecular attachment scheme, should enable interface engineering that optimizes the chemical selectivity of ZnO biosensors or the charge-transfer properties of ZnO−polymer interfaces found in oxide−organic electronics.

Abstract. Periodic mesoporous organosilicas (PMOs) are one of the most promising candidates to be used as ultra-low-k dielectrics in microelectronic devices. In this paper, PMO thin films that combine an ultra-low-k value, a hydrophobic property and a high resistance against aggressive chemical conditions are presented. The films are synthesized via spin-coating of a 1,1,3,3,5,5-hexaethoxy-1,3,5-trisilacyclohexane, hydrochloric acid, water and ethanol mixture using polyoxyethylene (10) stearyl ether as a porogen template. The obtained highly porous films are hydrophobic, crack-free and an ultra-low k-value of 1.8 is achieved. Finally, the chemical resistance of these PMO films against alkaline solutions is investigated in detail and compared with the resistance of mesoporous silicas and PMOs synthesized with cetyl trimethylammonium chloride.

Abstract. In the present study, surface modification of novel environment-friendly Rice Bran Carbon was carried out by mixed acid treatment followed by reaction with multifunctional silane, (3-Mercaptopropyl) trimethoxysilane. Then a new class of styrene-butadiene rubber/Rice Bran Carbon composites were prefabricated by using latex compounding method on the basis of pretreatment of RBC. Specifically, extra 3phr 3-MPTMS was added into the composites to construct a systematic filler-silane-matrix net framework. The chemical interaction mechanism of silane agent with the oxidized RBC was confirmed by Fourier Transform Infrared Spectroscopy, Energy Dispersive Spectroscopy, Thermogravimetric Analysis and Field Emission Scanning Electron Microscopy. The effect of silane modified RBC on the mechanical, wear and friction property of SBR vulcanizates was investigated.

Abstract. Mitochondria are the powerhouse of cells. They are vital organelles that maintain cellular function and metabolism. Dysfunction of mitochondria results in various diseases with a great diversity of clinical appearances. In the past, strategies have been developed for fabricating subcellular-targeting drug-delivery nanocarriers, enabling cellular internalization and subsequent organelle localization. Of late, innovative strategies have emerged for the smart design of multifunctional nanocarriers. Hierarchical targeting enables nanocarriers to evade and overcome various barriers encountered upon in vivo administration to reach the organelle with good bioavailability. Stimuli-responsive nanocarriers allow controlled release of therapeutics to occur at the desired target site. Synergistic therapy can be achieved using a combination of approaches such as chemotherapy, gene and phototherapy. In this Review, we survey the field for recent developments and strategies used in the smart design of nanocarriers for mitochondria-targeted therapeutics. Existing challenges and unexplored therapeutic opportunities are also highlighted and discussed to inspire the next generation of mitochondrial-targeting nanotherapeutics.
