Many studies are currently focusing on the mechanical properties of granite from macroscopic and microscopic perspectives, but only several influence rock mineral composition using a combined macro-micro assessment. The biotite in Gaoligong Mountains was selected as research object, variation strength characteristics at 20–130°C were obtained through uniaxial compression experiments. rock’s com...

Unique features of diatoms are their intricate cell covers (frustules) made out of hydrated, amorphous silica. The frustule defines and maintains cell shape and protects cells against grazers and pathogens, yet it must allow for cell expansion during growth and division. Other siliceous structures have also evolved in some chain-forming species as means for holding neighboring cells together. C...

The calcifuge and calcicole character of wild plants has been related to nutrient availability shortages, including iron (Fe)-deficiency. Surprisingly, just a few studies examined the relation between root Fe uptake and plant distribution in different soil types. We assessed the root Fe acquisition efficiency of two Ulmus species with calcareous (Ulmus minor) and siliceous (U. laevis) soil dist...

Abstract The abandonment of agricultural lands triggers a secondary succession plant species which implies important changes in soil quality. Annual Mediterranean grasslands are known to be persistent on abandoned agriculture the western Mediterranean. We used taxonomic and functional approaches determine role as an indicator ecosystem biodiversity functionality. tested hypothesis that suitable...

This study examines the performance of a new adsorbent, hexagonal nanostructured zeolite particles (HNZP) for acetone adsorption and compares the results with that of commercial mobil synthetic zeolite-5 (ZSM-5) type zeolite. The HNZP is a pure siliceous adsorbent with different values of pore diameter and surface area being adjustable by the manufacturing condition. The results indicate that a...
