The ion-acoustic instability in a dusty negative ion plasma is investigated, focusing on the parameter regime in which the negative ion density is much larger than the electron density. The dynamics of the massive dust grains are neglected, but collisions of electrons and ions with dust grains in addition to other collisional processes are taken into account. The presence of a population of cha...

Baterai merupakan salah satu komponen terpenting pada kendaraan listrik. Dari beberapa jenis aki yang ada di pasaran saat ini, Indonesia harus bisa mengkolaborasikan antara ketersediaan bahan baku dan teknologi pembuatan perakitan baterai tersebut agar dikembangkan efektif mampu bersaing pasaran. Penelitian ini dilakukan untuk mensimulasikan Lead Acid, Nickel Metal Hydride (NiMH), Lithium-ion (...

steel slags are the by products of steel industries, which forms during reduction process of iron melting. the chemical composition of it changes depending to the melting procedure. its mineralogical composition also varies based on the cooling procedure. two different types of steel slag were used as absorbing bed for various concentrations of pb2+ ions in the form of lead chloride, and the co...

Electron transfer in collisions between Rydberg atoms and targets that attach free low-energy electrons can lead to the formation of heavy-Rydberg ion-pair states comprising a positive-negative ion pair that orbit each other at large separations weakly bound by their mutual electrostatic attraction. It is shown that measurements of the velocity distribution of the ion-pair states produced in su...

Finite amplitude Alfvén-cyclotron waves are believed to play an important role in coronal heating and nonthermal properties of velocity distribution functions. These effects are thought to be due to parametrically unstable Alfvén-cyclotron waves and electrostatic bursts of ion-acoustic like waves. It is shown here that large amplitude Alfvéncyclotron waves propagating in multi-ion plasmas with ...

In partially ionized plasma, where ions can be in different ionization states, each charge state described as a fluid for the purpose of multi-ion collisional transport. case two transport pushes plasma toward equilibrium which is found to combination local and generalized pinch relations between ion fluids representing states. Combined, these conditions lead dramatic deconfinement ions. This h...

The staining of thin sections of Osmium tetroxide (OsO4)-fixed biological materials with the lead hydroxide preparat ion of Watson (5) or with semisaturated solutions of lead subacetate (1) represents a considerable advance in electron microscope technique. The contrast of the image viewed in the electron microscope is so far enhanced that accurate focusing is now possible at appreciably higher...
