Abstract Spin–orbit torque magnetic random-access memory exhibits great potential for next-generation memory. Annealing is an essential process SOT tunnel junctions (SOT-MTJs) thin films. To optimize the SOT-MTJ films, studying different dimensions from micro-size to nano-size very necessary. Here, we investigate annealing effect on magneto-electric properties of micro-scaled and nano-scaled SO...

Nano-fibrillated cellulose was produced from flax and wheat straw cellulose pulps by high pressure disintegration. The reinforcing potential of both disintegrated nano-celluloses in a polyvinyl-alcohol matrix was evaluated. Disintegration of wheat straw was significantly more time and energy consuming. Disintegration did not lead to distinct changes in the degree of polymerization; however, the...

The present research effort developed a real-space formulation for orbital-free density functional theory and Kohn-Sham density functional theory in order to conduct large-scale electronic structure calculations that take an important step towards addressing the prevailing domain-size and geometry limitations of existing electronic-structure codes. In particular, by combining the real-space for...

Ge and B diffusion was studied in nano-crystalline Si, and Pd and Si self-diffusion was studied in nano-crystalline Pd2Si during and after Pd/Si reactive diffusion. These experiments showed that grain boundary (GB) diffusion kinetic is the same in microand nano-GBs, whereas triple junction (TJ) diffusion is several orders of magnitude faster than GB diffusion. In addition, GB segregation and GB...

Field emission has been reported to occur at much lower fields in carbon based thin film systems than from any other material systems. The emission has been shown to depend on the various material parameters, but whichever carbon based system is used, it is found that emission occurs at localised sites rather than uniformly over the entire surface. Carbon films with mixed sp3 sp2 bonding, like ...

In this paper, ZnO thin film is deposited on slide glass substrate using the sol-gel process. Presenting well-defined orientation of ZnO thin films Nanostructure were obtained by dip coating of zinc acetate dihydrate, monoethanolamine (MEA), de-ionized water and isopropanol alcohol. The annealed ZnO thin films were transparent ca 85-90% in visible range with an absorption edges at about 375 nm....

We experimentally demonstrate that hybridized nanocavities in optically thick metal films radiate in coherence, and act as an efficient single-polarized plasmonic nano-antenna array. We employ propagating and localized plasmons to enhance polarization control along one axis, with total suppression of the perpendicular polarization component. The relationship between the near-field and far-field...

We report the development of a pulsed inductive microwave magnetometer for measurements of ultra fast magnetization dynamics of soft magnetic thin films. This article details the instrument construction and the measurement procedure. We show experimentally that our instrument detects nano-second and sub-nano second magnetization precession / relaxation processes, in real time, without the need ...

Halloysite nanotubes (HNTs) were loaded with lsozyme, as antimicrobial molecule, at a HNTs/lysozyme ratio of 1:1. Such a nano-hybrid was incorporated into a poly (ε-caprolactone) (PCL) matrix at 10 wt % and films were obtained. The nano-composites were submitted to a cold drawn process at three different draw ratios, λ = 3, 4, and 5, where λ is l(final length)/l0(initial length). Morphology, ph...
