Stress-induced phase transformation and pseudo-elastic/pseudo-plastic recovery in intermetallic Ni-Al nanowires.
TL;DR: A stress inducedcentered-tetragonal (BCT) phase transformation and a novel temperature and cross-section dependent pseudo-elastic/pseudo-plastic recovery from such an unstable BCT phase with a recoverable strain of approximately 30% as compared to 5-8% in polycrystalline materials are shown.
Journal ArticleDOI
Lamb wave based monitoring of plate-stiffener deboding using a circular array of piezoelectric sensors
Vivek T. Rathod,D. Roy Mahapatra +1 more
TL;DR: In this paper, the authors proposed an efficient way of localization and parametric identification of metallic plate-stiffener debonding based on a circular array of piezoelectric Wafer Active Sensors (PWASs).
Journal ArticleDOI
Carbon Nanotube Thin Film Field Emitting Diode: Understanding the System Response Based on Multiphysics Modeling
TL;DR: In this article, the evolution and self-assembly of randomly oriented carbon nanotubes (CNTs), grown on a metallic substrate in the form of a thin film for field emission under diode configuration, is studied.
Journal ArticleDOI
Pathogenic Escherichia coli (E. coli) detection through tuned nanoparticles enhancement study.
Gargibala Satpathy,Gargibala Satpathy,Goutam Kumar Chandra,Elayaperumal Manikandan,Elayaperumal Manikandan,D. Roy Mahapatra,Siva Umapathy,Siva Umapathy +7 more
TL;DR: It is concluded that when two E. coli strains are respectively mixed and kept overnight, the growth of bacteria are inhibited by ZnO-NPs due to changes in cell membrane permeability and intracellular metabolic system under fluorescence microscopy, however, SPR possessed Au-nPs result in enhanced fluorescence of both pathogens.
Journal ArticleDOI
Prophylactic Effects of Propranolol versus the Standard Therapy on a New Model of Disuse Osteoporosis in Rats.
TL;DR: It is shown that the bone resorption induced by immobilization/disuse in rats can be suppressed by treatment with propranolol, and the anti-osteoporotic property of propr ethanol was comparable with zoledronic acid and alfacalcidol.
