Recent studies have revealed new unstable regimes of the counter-beaming electrons specific to hot and dilute plasmas from astrophysical scenarios. The (counter-)beaming electron firehose instability (BEFI) is induced for highly oblique angles of pro
On the interplay of solar wind proton and electron instabilities: linear and quasi-linear approaches
Important efforts are currently made for understanding the so-called kinetic instabilities, driven by the anisotropy of different species of plasma particles present in the solar wind and terrestrial magnetosphere. These instabilities are fast enough

In collision-poor space plasmas the main physical processes are governed by fluctuations and their interactions with plasma particles. An important source of waves and coherent fluctuations are kinetic instabilities driven by, e.g., protons and elect

Classification of volcanic rocks is a fundamental task in the geologic studies. Volcanic rocks are igneous rocks that cooled rapidly above the surface of the Earth's crust. They are classified according to their oxide chemical content. Furthermore, v

A novel coumarin hydrazide ligand derived from the condensation of 7-hydroxy coumarin-4-ethylacetate with salicylaldehyde hydrazone and its complexes with Sm(III) and Eu(III) have been synthesized. The ligand and its complexes have been characterized

Local rice husk ash was precleaned with chemical treatment using NaOH and HCl solutions and well incorporated with other components forming zeolites; under hydrothermal conditions, to synthesize ZSM-5. ZSM-5 zeolites were characterized with several t
