The first life was believed to emerge in the early Earth via a process involving synthesis of organic compounds and formation protocells. However, it is still puzzle how protocell with hierarchal structure desirable functions spontaneously generated non-living environment composed mainly water minerals. In this work, using muscovite as an example minerals, we systemically studied coacervation p...

abstract the association between neotyphodium spp. endophytes and cool-season grasses, particularly tall fescue (festuca arundinacea, schreb), represents a widespread type of mutualism in nature. numerous researches were performed about positive effect of symbiosis on plant resistance to different stresses but the role of symbiosis on nutrients uptake particularly potassium uptake and k-bearing...

That some of the potassium added in the form of fertilizers or otherwise becomes fixed in the soil had been known for a long time. With the clarification of the phenomena of base exchange in soils by Gedroiz it was revealed that the K-ion is fixed in the exchange complex not only in replaceable but also in non-replaceable form. A review of the work in this connection may be found in the paper b...

The high temperature treatment of kaolinite-muscovite alternate layers doped by bismuth oxide was studied by TGA and DTA, X ray diffraction, and electron microscopy (SEM). Thermal analyses shows that the two main transformation stages are the dehydroxylation of phyllosilicates and the structural reorganization of the whole assembly. During dehydroxylation, a progressive decrease of the structur...

Muscovite is a major constituent mineral in the continental crust that exhibits very strong seismic anisotropy. alignment rocks can significantly affect magnitude and symmetry of In this study, deformation microstructures muscovite-quartz phyllites from Geumseongri Formation Gunsan, Korea, were studied to investigate relationship between muscovite chlorite fabrics strongly deformed anisotropy o...

Defined crystal growth is highly demanded for technological applications but also fundamental research. Within this work, the crystal growth of the asymmetric molecule caffeine was studied on single crystalline surfaces of muscovite mica, sodium chloride and potassium chloride. While elongated needle-like crystals grow on muscovite mica and sodium chloride, smaller individual "bird-like" struct...

The Christian-Muslim frontier frequently acted as a barrier that separated religions, cultures, and societies from one another. But it was a permeable barrier in that ideas, commodities, and technology often passed through it. To demonstrate the precise mechanism of that permeability can be difficult to do. As Lynn White has remarked: ‘‘No medieval text documents with explicit words the amazing...
