Hydrogen storage by reduced graphene oxide and graphene-like nanosheets decorated with Fe nanoclusters

Hudson M.S.L., Srivastava O.N., Simizu S., Sankar S.G., Central University of Tamil Nadu, IN

Here, we present the high pressure hydrogen sorption isotherm up to 50 bar of graphene oxide (GO) reduced by thermal reduction (TR-GO), chemical reduction (CR-GO) and graphene like nanosheets decorated with Fe nanoclusters (Fe-GS). GO [...]

Hydrogen Recharge Dynamics and Vessel Design for Porous Silicon Storage Media

Schubert P.J., Urbanek A., IUPUI, US

Porous silicon as a storage media can store up to 7.1% hydrogen by weight [1,3]. The round-trip energy difference is 1.2 kJ/mol, but the as-synthesized energy barrier requires 410 C for complete thermal discharge [2]. [...]

3-Dimensional Carbon Nanotube-Graphene Structure for Flexible Li-ion Battery

Kang C., Baskaran R., Mumukshu P., Choudhary N., Choi1 W., University of North Texas, US

Flexible electronics have attracted great attention for use in next-generation portable devices and their major applications include roll-up displays, wearable devices, active radio frequency identification (RFID) tags, integrated circuit smart cards and implantable medical devices. [...]

Capturing and Using CO2 as Feedstock for Clean Chemical Processes Technologies

Demirel Y., University of Nebraska Lincoln, US

Chemical-looping technology for capturing CO2 are discussed with critical assessments of the circulating fluidized bed systems and the packed bed reactor with periodic switching of the feed streams of fuel and air. Beside, some industrial [...]

Pelletized silica and polyethyleneimine composites for CO2 capture via adsorption

Knowles G.P., Chaffee A.L., Monash University, AU

Amine adsorbent powders are of broad interest to facilitate CO2 capture towards reducing atmospheric greenhouse gas. It is recognized, however, that industrial adsorption processes require pelletized rather than powdered adsorbents. Mesoporous silica and branched polyethyleneimine [...]

Development of the Novel Functionality of Probiotics Fermented Noni Hydrolysates

Yin L.J., Lee H.-H., Wu J.J., Jiang S.T., National Kaohsiung Marine University, TW

This study aimed to help the release of functional nutrients from noni fruit by enzymatic hydrolysis, and to subsequently shorten the fermentation time during the biotransformation of some compounds. This study firstly investigated the optimal [...]

Commercial pilot for closed-loop wastewater treatment and biofuel production using microalgae

Atwood M., Novoveska L., Sundstrom E., Valdez P., Algae Systems LLC, US

In wastewater treatment, significant energy is used to dilute, discharge, or landfill valuable resources. This situation is untenable due to energy costs and global scarcity of clean water. Algae Systems has developed and patented a [...]

Analysis of low temperature effects on the performance of SEPIC in a fuel cell system

Noh M.D., Kim S., Park Y.W., Chungnam National University, KR

A single-ended primary-inductance converter (SEPIC) is to be used at the output of a direct-methanol fuel cell (DMFC) system. In this paper, SEPIC is investigated in terms of the performance variations when the operating temperature [...]

Enhanced fuel cell performance with modified Nafion® membranes

Krishnan L., Yeager G., Clark K., Kerr J., Soloveichik G., Miebach T., GE Global Research, US

The interaction of Nafion® 212 membrane with a carbocyclic fuel, decalin was studied. Decalin treatment of N212 improved vapor sorption and membrane conductivity. In addition a substantial increase of peak power in a H2/Air fuel [...]

Molecular Hydrogen Storage in Fullerenes for Use on Board Fuel Cell Vehicles – A Density Functional Theory Study

Durbin D.J., Allan N.L., Malardier-Jugroot C., Royal Military College, CA

Hydrogen gas is a potential fuel to replace gasoline on board vehicles. However, viable storage methods must be developed. Carbon nanomaterials are promising because they are cheap, lightweight and abundant but carbon-hydrogen physisorption is weak [...]
