Structure-Property Relations on Strain-Mediated Multiferroic Heterostructures
… materials like BiFeO3 (BFO) thin films, and strain-mediated magnetoelectric (ME) nanocomposites, have the potential to fulfill a number of functional requirements in actual applications—principally, direct control of magnetization by the application of an electric field (E) and vice-versa. …

Mechanical Strain-Mediated Syndecan Regulation and Its Effects on Adhesion of Vascular Smooth Muscle Cells
… centrifugation assay, and an antisense-mediated reduction in gene expression was found to correlate with decreased adhesive strength. Regulation of syndecan-1, syndecan-2, and syndecan-4 gene expression was observed experimentally by mechanical strain of SMCs. Using real-time polymerase …

Weak Commitment to School, Deviant Peers, and Cyberbullying Victimization-Strain in Adolescent Cyberbullying
… deviant peers, and cyberbullying victimization-strain variables can explain cyberbullying offending. In addition, it attempts to explain the mediation effects among weak commitment to school, deviant peers, cyberbullying victimization-strain, and cyberbullying offending variables. Using data …

Imaging magnetic order in magneto-structural phases of Mn3O4
… We attribute the magnetic patterns observed to strain-mediated phase separation. Phases are separated by a unique wall type, stabilized by the magneto-elastic coupling in Mn3O4. This result and the technique developed enable study of similar phase separation behaviors in related strongly …

Anisotropic behaviour of magneto-electric coupling in multiferroic composites
… textured nickel ferrite/lead zirconate titanate strain mediated bilayer composites has been studied. The magnetic layers of these samples have been crystallographically textured in planes of the form {100}, {110} and {111}. In this study, it is shown that the optimum bias field and the maximum …

Investigation of the effects of Mechanical Strain in Human Tenocytes
… aims to investigate the effect of cyclic tensile strain loading and TGFβ stimulation on protease and ECM protein expression by human tenocytes and begin to characterise the pathway of mechanotransduction. Human tenocytes were seeded at 1.5x106 cells/ml into collagen gels (rat tail type I, 1mg/ml) …

Caloric effects in ferroic materials
… effects in La0.7Ca0.3MnO3 (LCMO) driven using strain. LCMO’s intrinsic caloric effect near its ferromagnetic transition is small (-1.2 J kg−1 K−1 T−1 ) [1]. Moya et al. have discovered that LCMO thin films grown on BaTiO3 (BTO) substrates can produce extrinsic magnetocaloric effects as large as …

Gender differences in coping: Implications for depression and crime
… from social psychological theories of stress and strain, I sought to build on earlier approaches to gender and coping by applying the stress process model to both mental health and criminological outcomes. Based on a representative sample of 1,803 young adults in Miami-Dade County, Florida, I …

Transmission Electron Microscopy Study of Domains in Ferroelectrics
… that the relaxation of the out-of-plane constraint gives rise to an undetermined set of linear equations which can be solved for compatible domain wall orientations and volume fractions of domains, indicating that groups of adjacent grains can form stress-free domain patterns. STEM in-situ …
