Ultrasonic guided wave sensing properties of PVDF thin film with inter digital electrodes
Vivek T. Rathod,D. Roy Mahapatra +1 more
TL;DR: In this paper, a large area PVDF with Inter Digital Electrodes (IDE) was used for ultrasonic strain sensing at very high frequencies of 200 kHz, where the authors used a laser Doppler Vibrometer (LDV) and a wave propagation model.
Journal ArticleDOI
Effects of Isothermal and Adiabatic Thermal Loadings on Size and Strain Rate Dependence of Copper Nanowire
TL;DR: In this article, the effect of strain rate on the mechanical properties of copper nanowires was analyzed, which showed that elastic properties are independent of thermal loading for a given strain rate and cross-sectional dimension of nanowire.
Proceedings ArticleDOI
Photonic hydrogel beads for controlled release of risedronate
TL;DR: In this article, a photonic composite hydrogel beads composed of sodium alginate and risedronate sodium (SA/RIS) was prepared crosslinked by Ca 2+ owing to the ionic gelation of SA.

Role of electrodes on perovskite solar cells performance: A review
Proceedings ArticleDOI
Electronic band Structure and Photoemission Spectra of Graphene on Silicon Substrate
Brahmanandam Javvaji,Abhilash Ravikumar,Bhamy Maithry Shenoy,D. Roy Mahapatra,M. R. Rahman,G. M. Hegde +5 more
TL;DR: A combination of molecular dynamics and density functional theory has been used to predict the electronic energy band structure and photo-emission spectrum for graphene-Si system with silicon as a substrate for graphene as discussed by the authors.
