The kinetics of nanocrystallization and microstructural observations in FINEMET, NANOPERM and HITPERM nanocomposite magnetic materials

This paper presents experimental observations of the nanocrystallization process in materials having Fe–Si (FINEMET), a-Fe (NANOPERM), and a0-FeCo (HITPERM) nanocrystals coupled through an amorphous phase. Crystallization kinetics and chemical partitioning during crystallization are described. Isothermal nanocrystallization is discussed in the framework of the Johnson–Mehl–Avrami–Kolmogorov mod...

the effect of authentic listening materials on the listening proficiency of efl learners in the intermediate level

having conducted the experiment and analysed the data, the researcher computed the groups mean scores and variances for the test relating to the research question. as the final atep, a t-test was conodonted for the hypothesis. as noted earlier, the significance level was determined at .05 and .01 respectively. the observed t-value was higher than the critical t-value at. 5 and .01 levels. conse...

Nanomechanics of Amyloid Materials Studied by Atomic Force Microscopy

Amyloids are usually used to refer to a wide range of fibrous nanostructures formed from natural and synthetic proteins and peptides. The self-propagating protein aggregates are rich in ┚-sheets, which stack in hundreds to thousands units perpendicular to the fibrous axis, forming fibrils 5-15 nm in width and several micrometers in length (Dobson, 1999; Jaroniec et al., 2004; Luhrs et al., 2005...

Porosity of Low-κ Materials Studied by Slow Positron Beam

Until the past few years, aluminium was used in semiconductor technology as interconnect metal and silicon dioxide (SiO2, κ = 3.9) as the interand intra-level insulator. With the demand of scaling the dimension of advanced integrated circuits well below the 100 nm DRAM 1/2 pitch technology node [1], the signal delay (resistance–capacitance RC delay) becomes one limitation in increasing the spee...
