Quasi-monoenergetic carbon ions generation from a double-layer target driven by extreme laser pulses

New Journal of Physics, 2023
High quality energetic carbon ions produced via laser-plasma have many applications in tumor therapy, fast ignition and warm dense matter generation. However, the beam achieved in current experiments is still limited by either a large energy spread or a ...

Simulations of stable compact proton beam acceleration from a two-ion-species ultrathin foil

, 2011
We report stable laser-driven proton beam acceleration from ultrathin foils consisting of two ion species: heavier carbon ions and lighter protons. Multi-dimensional particle-in-cell (PIC) simulations show that the radiation pressure leads to very fast ...

Determination of carbonate ion by ion chromatography.

BUNSEKI KAGAKU, 1996
Determination of carbonate ion by ion chromatography was investigated. The separation was performed on a TSKgel IC-Anion-PWXL (4.6 mm i.d.×35 mm) with boric acid-ethylenediamine buffer. The influence of the eluent pH on the capacity factors of carbonate and some inorganic anions was studied.

Helium-3 and Helium-4 acceleration by high power laser pulses for hadron therapy

, 2015
The laser driven acceleration of ions is considered a promising candidate for an ion source for hadron therapy of oncological diseases. Though proton and carbon ion sources are conventionally used for therapy, other light ions can also be utilized ...

Fe-substituted mullite powders for the in situ synthesis of carbon nanotubes by catalytic chemical vapor deposition [PDF]

, 2009
Powders of iron-substituted mullite were prepared by combustion and further calcination in air at different temperatures. A detailed study involving notably Mo¨ssbauer spectroscopy showed that the Fe3+ ions are distributed between the mullite phase and a

Effect of impurities on the transition between minority ion and mode conversion ICRH heating in (3He)-H tokamak plasmas [PDF]

, 2013
Hydrogen majority plasmas will be used in the initial non-activated phase of ITER operation. Optimizing ion cyclotron resonance heating (ICRH) in such scenarios will help in achieving H-mode in these plasmas.

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)
