We have theoretically demonstrated that phonon heat flux can be significantly suppressed in Si and Si/SiO2 nanowires with the periodically modulated cross-section area—referred to as the cross-section-modulated nanowires—in comparison with the generic uniform cross-section nanowires. The phonon energy spectra were obtained using the five-parameter Born–von Karman-type model and the face-centere...

BACKGROUND AND OBJECTIVES Infant mortality is an indicator of overall societal health, and a significant proportion of infant deaths occur in NICUs. The objectives were to identify causes of death and to define potentially preventable factors associated with death as areas for quality improvement efforts in the NICU. METHODS In a prospectively defined study, the principal investigator in 46 l...

Medical care of infants in the neonatal intensive care unit (NICU) is so complex that professionals have been almost exclusively responsible for providing care to the infants and information to their families. Although federal law now mandates early intervention programs and service providers to include families in decision making and treatment implementation for their children, family-centered...

This thesis involves an extensive experimental and theoretical study of the thermoelectric-related transport properties of Bii_2Sb. nanowires, and presents a theoretical framework for predicting the electrical properties of superlattice nanowires. A template-assisted fabrication scheme is employed to synthesize Bi-based nanowires by pressure injecting liquid metal alloys into the hexagonally pa...

in this study, we synthesis one-dimensional (1d) manganese(iii) schiff base coordination polymer [mn(brsalophen)(μ1,3-n3)]n by reaction of mncl2·6h2o and tetradentate schiff base ligand brsalophen at the presence of nan3 in methanol and characterized by elemental analyses (chn) and ft-ir spectroscopy. it was used as a new precursor to prepare spinel type manganese oxide nanowires by a facile so...

We have synthesized and characterized three types of perovskite alkaline niobate nanowires: NaNbO(3), KNbO(3), and LiNbO(3) (XNbO(3)). All three types of nanowires exhibit strong nonlinear response. Confocal imaging has been employed to quantitatively compare the efficiency of synthesized nanowires to generate second harmonic signal and to show that LiNbO(3) nanowires exhibit the strongest nonl...

The thermal conductivity of individual single-crystalline Bi nanowires grown by the on-film formation of nanowires (ON-OFF) has been investigated. We observed that the thermal conductivity of single-crystalline Bi nanowires is highly anisotropic. Thermal conductivity of nanowires (diameter ∼100 nm) in the off-axis [102] and [110] directions exhibits a difference of ∼7.0 W/m·K. The thermal condu...

piezoelectric nanobeams having circular, rectangular and hexagonal cross-sections are synthesized and used in various nano structures; however, piezoelectric nanobeams with hexagonal cross-sections have not been studied in detail. in particular, the physical mechanisms of the surface effect and the role of surface stress, surface elasticity and surface piezoelectricity have not been discussed t...

OBJECTIVES To determine the proportion of infants admitted to our neonatal intensive care unit (NICU) from multiple gestations resulting from artificial reproductive technology (ART), the complications experienced and interventions required by these infants, and the estimated effect of a mandatory policy of single embryo transfer on admissions and complication rates in our hospital and across C...

The aim of this article is to articulate the essence and constituents of neonatal intensive care unit (NICU) nurses' experiences in enacting skin-to-skin care (SSC) for preterm newborns and their parents. SSC is commonly employed in high-tech NICUs, which entails a movement from maternal-infant separation. Parents' opportunities for performing the practice have been addressed to NICU staff, wit...
