Transparent conducting electrodes based on thin, ultra-long Copper nanowires and graphene nano-composites
(
SPIE
, 2014 , Conference Paper)
High aspect-ratio ultra-long (> 70 ?m) and thin (< 50 nm) copper nanowires (Cu-NW) were synthesized in large quantities using a solution-based approach. The nanowires, along with reduced graphene-oxide sheets, were coated ...

A case study on innovation and creativity in engineering design instruction has been presented. The novel approach emphases on the role of student engagement, team spirit and industry support to students. This paper presented ...
Highly transparent low sheet resistance electrodes for solar cell applications
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
High aspect ratio copper nanowires were synthesized, using a solution-based approach. The nanowires along with reduced graphene oxide thin films were sprayed onto glass and flexible substrates and later annealed in order ...
Metal nanowire-graphene composite transparent electrodes
(
SPIE
, 2014 , Conference Paper)
Silver nanowires with 40 nm diameter and copper nanowires with 150 nm diameter were synthesized using low-temperature routes, and deposited in combination with ultrathin graphene sheets for use as transparent conductors. ...
Non-invasivemonitoring of fetal movements using time-frequency features of accelerometry
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
This paper presents a time-frequency approach for fetal movement monitoring which is based on the instantaneous amplitude (IA) and instantaneous frequency (IF) of signals collected using 3axial accelerometers placed over ...
Solar thermochemical conversion of CO2 into synthetic fuels via ferrite based redox reactions
(
AIChE
, 2014 , Conference Paper)
In this contribution, we report the synthesis NiFe2O4 and CoFe2O4 redox materials via sol-gel method. For the synthesis of these materials via sol-gel approach, the Ni, Co, and Fe precursors were first dissolved in ethanol ...
Solution combustion synthesis of active catalysts for hydrogen production from ethanol
(
AIChE
, 2014 , Conference Paper)
Solution combustion synthesis method was used to synthesize Cu and Ni based catalysts active for hydrogen production from ethanol decomposition reaction. The catalyst synthesis parameters (such as fuel to oxidizer ratio, ...
