Normal Electrochemical Deposition NiFe

Due to heating of the electrolyte is an excluded abnormal codeposition alloy components and reduced variation of process parameters to achieve optimal magnetic properties Ni81Fe19 films of magnetic field concentrators. Proposed chloride electrolyte pH adjusted with hydrochloric acid, which provides congruent electrochemical deposition of permalloy at heating and stirring. Magnetic properties of permalloy films are very sensitive to the variation of component relationships of 4.26. Control of accuracy of preparation of chloride electrolyte for electrochemical deposition of NiFe conducted using spectrophotometry. It is shown that the selection process of cooking the electrolyte for electrodeposition of Ni81Fe19 alloy and temperature allow to get normal, congruent electrochemical deposition of permalloy films. It has been established that the anomalous character of permalloy deposition associated with the main feature of iron ions-the existence of variable Valence iron with two or three values in the charge of ions during the hydrolysis of iron salts.

Anomalous molecular infiltration in graphene laminates

Molecular transport in graphene laminated coatings exhibits anomalous character: penetrant infiltration occurs through molecular-sized nano-channels having distributed path lengths.

The Teotihuacan Anomaly: The Historical Trajectory of Urban Design in ancient Central Mexico

The ancient Mexican city of Teotihuacan had the most aberrant design of any city in ancientMesoamerica. I examine similarities and differences between the design of Teotihuacan and otherMesoamerican cities. During the Preclassic period, a set of common Mesoamerican planning principlesemerged. The designers of Teotihuacan rejected most of these principles in favor of a new and radical setof planning concepts. After the fall of Teotihuacan, subsequent urban planners ignored the Teotihuacanprinciples and returned to ancient Mesoamerican planning ideas. Elements of the Teotihuacan plan didnot resurface until the Mexica of Tenochtitlan revived them for a specific goal. The historical sequenceof central Mexican city layouts highlights the anomalous character of Teotihuacan’s principles of urbandesign within the canons of ancient Mesoamerican urbanism.
