In this study, we have investigated amorphous 20-nm-thick Tb/Fe80Co20 multilayer samples with different individual layer thicknesses and their corresponding alloy counterpart. particular, the structural magnetic properties were analyzed upon post-annealing. Up to a certain critical thickness of layers in multilayer, no significant difference between multilayers is observed as-deposited states, ...

Abstract The Gd thickness dependence of spin–orbit torque (SOT) and critical current density SOT switching in ferrimagnetic Gd/FeCo multilayers grown on a Ta seed layer was investigated compared with the results GdFeCo alloy/Ta bilayers. Critical J sw almost same as those alloy films. magnitudes damping-like field-like effective fields, H DL FL , respectively, were confirmed to increase near co...

Synchrotron far-IR spectroscopy and density-functional calculations are used to characterize the low-frequency dynamics of model heme FeCO compounds. The "doming" vibrational mode in which the iron atom moves out of the porphyrin plane while the periphery of this ring moves in the opposite direction determines the reactivity of oxygen with this type of molecule in biological systems. Calculatio...

BACKGROUND Neonatal appendicitis is difficult to diagnose, and is associated with high mortality. CASE CHARACTERISTICS A preterm (33 wk) neonate developed abdominal distension feeding intolerance and erythema of left inguinal region on day 4 of life. OBSERVATION Testicular torsion was suspected but inguinal exploration revealed normal testis with feco-purulent fluid draining into processus ...

Abstract The manipulation of polymeric micelles across extended-length scales is a key challenge in the design integrated mesoporous materials with well-defined geometry and advanced functions. Herein, we demonstrate modular assembly strategy to construct metal nanoparticle functionalized carbon two-dimensional (2D) nanosheets by organizing zero-dimensional (0D) spherical monomicelle modules on...

Helicobacter pylori is a worldwide spread bacterium, that invades the submucosal membrane of stomach via feco-oral or feco-fecal transmission, causing several gastric and duodenal diseases. The study aims to assess risk factors for symptomatic infection their epidemiological distribution. A cross-sectional was conducted from October 2020 May 2021 in Baquba, Iraq. It on sample outpatient patient...

In CO 2 environments, an increase in the temperature can influence carbon steel flow-induced corrosion (FIC) and erosion-corrosion (EC) degradation processes. Increasing typically results acceleration of electrochemical mechanisms absence protective product layers. Furthermore, presence sand corrosive process fluids could aggravate service conditions. Although iron carbonate (FeCO 3 ) film or/a...

The combination of nanostructured transition metal oxides and carbon materials is a promising approach to obtain inexpensive, highly efficient, stable bifunctional electrocatalysts for the oxygen reduction (ORR) evolution (OER) reactions. We present strategy improving ORR/OER activity supported FeCoOx nanoparticles by tuning properties multi-walled nanotubes (MWCNT) via nitrogen doping during t...
