A silicon-based microfabricated fuel cell running on formic acid vapor as a fuel has been developed to provide on-chip power for MEMS devices, without using any ancillary devices such as heaters, water management, air pumps, etc. As a demonstration instrument, an integrated silicon-based membrane electrode assembly and fuel evaporative structure was packaged in a plastic package to test the vap...

The primary objective of this paper is to enhance the water-vapor-adsorption capacity of multiwall-carbon-nanotube (MWCNT) from nitrogen gas by grafting sulfonic acid groups and doping palladium nanoparticles into the adsorbent. MWCNT has been selected to be modified because of having homogeneous adsorption energy compared to silica gel. As a result, it is capable of creating isotherm having sh...

We report the discovery of a layer of enhanced water vapor in the Arctic summer mesosphere that was made utilizing two new techniques for remotely determining water vapor abundances. The first utilizes Middle Atmosphere High Resolution Spectrograph Investigation (MAHRSI) OH measurements as a proxy for water vapor. The second is a reanalysis of Halogen Occultation Experiment (HALOE) water vapor ...

polyamide 6 has been widely used in food packaging applications and also green tea contains amounts of antioxidant compounds. the aim of this study was investigation of green tea effects on properties of polyamide packaging polymer. polyamide 6 was dissolved in methanol which was saturated with calcium chloride. the active packaging film was produced by incorporation of methanol green tea extra...

novel citric acid modified starch-carboxy methyl cellulose (cmc) -montmorillonite (mmt) bionanocomposite films were prepared by casting method and the effect of mmt on the structural and physical properties of the starch-cmc biocomposites was studied. x-ray diffraction test showed thatstrong polar interactions between the hydroxyl groups present in the starch and cmc chains and in the silicate ...

polylactic acid based biodegradable nanocomposites reinforced with acetylated nanocellulose were fabricated with solution casting procedure. the nanocomposites were prepared by adding 1, 3 and 5% nanofiber loadings. the microstructure, physical, mechanical and thermal properties of the prepared nanocomposites were investigated. scanning electronic microscope (sem) analysis of the composites con...
