Density Functional Theory points to a key role of K(+) solvation in the low-energy two-dimensional arrangement of water molecules on the basal surface of muscovite. At a coverage of 9 water molecules per 2 surface potassium ions, there is room to accommodate the ions into wetting layers wherein half of them are hydrated by 3 and the other half by 4 water molecules, with no broken H-bonds, or wh...

An intergrowth of mucovite and biotite from Mitchell Creek Mine, Upson County, Georgia, was studied with a high resolution transmission electron microscope. Atomic arrangements of the interface between muscovite and biotite have been derived, revealing far more complexity for the interface structure than that proposed previously based on optical and X-ray analysis (Gresens and Stensrud, l97l). ...

By taking advantage of the mechanical anisotropy of crystalline materials, processing at a single-layer level can be realized for layered crystalline materials with periodically weak bonds. Mica (muscovite), graphite, molybdenum disulfide (MoS2), and boron nitride have layered structures, and there is little interaction between the cleavage planes existing in the basal planes of these materials...

abstract low molecular weight carboxylic acids (lmw) play an important role in improving the bioavailability of soil nutrients. nonexchangeable soil k, trapped between the interlayers of clay minerals, is an important source of k for plants in many soils. the objectives of this study were to determine the effect of selected lmw organic acids on the release of k from micaceous minerals and to in...

Abstract In modern technology, recent advances in multi-functional devices are rapidly developed for the diverse demands of human beings. Meanwhile, durability and adaptability to extreme environmental conditions also required. this study, a flexible magnetoelectric (ME) heterostructure based on CoFe 2 O 4 /Pb(Zr,Ti)O 3 composite thin film muscovite is presented, with two geometries constituent...

Field evidences, petrographic features and geochemical studies show that the garnet-muscovite granitoids of Boland Parchin area are S-type and they have sharp contact with the host rocks (metamorphic rocks). Granitoids of Boland Parchin contain minerals such as quartz, K-feldspars, plagioclase, biotite and Al-rich minerals (such as muscovite and garnet). Chemical composition of K-feldspars, pla...
