Highly textured and transparent RF sputtered Eu2O3 doped ZnO films. (2015)
Journal Article
SREEDHARAN, R. S., GANESAN, V., SUDARSANAKUMAR, C. P., BHAVSAR, K., PRAHBU, R. and PILLAI, V.P.P.M., 2015. Highly textured and transparent RF sputtered Eu2O3 doped ZnO films. Nano reviews [online], 6, Article 26759. Available from: https://doi.org/10.3402/nano.v6.26759

Background: Zinc oxide (ZnO) is a wide, direct band gap II-VI oxide semiconductor. ZnO has large exciton binding energy at room temperature, and it is a good host material for obtaining visible and infrared emission of various rare-earth ions. Method...

The prospect of deepwater heavy oil production using CO2-EOR. (2015)
Journal Article
TCHAMBAK, E., OYENEYIN, B. and OLUYEMI, G. 2015. The prospect of deepwater heavy oil production using CO2-EOR. Energy sources, part A: recovery, utilization and environmental effects [online], 37(3), pages 318-325. Available from: https://doi.org/10.1080/15567036.2011.585373

The prospect of unconventional oil development has long been coming to offset the rapid decline of conventional crude. And looking ahead, the worry is already turning away from the onshore exploitation to the challenging offshore environment, with th...

Angular dependent light emission from planar waveguides. (2015)
Journal Article
PETER, J., PRABHU, R., RADHAKRISHNAN, P., VALLABHAN, C.P.G., NAMPOORI, V.P.N. and KAILASNATH, M. 2015. Angular dependent light emission from planar waveguides. Journal of applied physics, 117(1), Article 015301. Available from: https://doi.org/10.1063/1.4905011

We have investigated the angular dependence of amplified spontaneous emission (ASE) and laser emission from an asymmetric and free-standing polymer thin films doped with rhodamine 6G, which is transversely pumped by a pulsed Nd:YAG laser. A semi-leak... Read More about Angular dependent light emission from planar waveguides..

Suppressing stick-slip oscillations in underactuated multibody drill-strings with parametric uncertainties using sliding-mode control. (2015)
Journal Article
