Ions and carbon nanostructures
Radiation Effects and Defects in Solids, 2013First experiments on swift ion irradiation of highly oriented pyrolythic graphite led to formation of carbon nanotubes (CNT) at the cascade eruption points. CNT length was in the micron range, which corresponded to an explosive crystallization of the carbon plume with about sound velocity.

Cleaving carbon-carbon bonds in cyclopropenium ions
Journal of the American Chemical Society, 1980A cyclopropenium ion breaking one of its carbon-carbon bonds furnishes an orbital template which can be exploited by sundry mononuclear and binuclear transition metal fragments.

Carbon Electrodes for K-Ion Batteries
Journal of the American Chemical Society, 2015We for the first time report electrochemical potassium insertion in graphite in a nonaqueous electrolyte, which can exhibit a high reversible capacity of 273 mAh/g. Ex situ XRD studies confirm that KC36, KC24, and KC8 sequentially form upon potassiation, whereas depotassiation recovers graphite through phase transformations in an opposite sequence ...

Clinical Indications for Carbon Ion Radiotherapy
Clinical Oncology, 2018Compared with photon and proton therapy, carbon ion radiotherapy (CIRT) offers potentially superior dose distributions, which may permit dose escalation with the potential for improved sparing of adjacent normal tissues. CIRT has increased biological effectiveness leading to increased tumour killing compared with other radiation modalities.

Microdosimetry of proton and carbon ions
Medical Physics, 2014Purpose:To investigate microdosimetry properties of 160 MeV/u protons and 290 MeV/u12C ion beams in small volumes of diameters 10–100 nm.Methods:Energy distributions of primary particles and nuclear fragments in the beams were calculated from simulations with the general purpose code SHIELD‐HIT, while energy depositions by monoenergetic ions in ...

Metal Ion Function in Carbonic Anhydrase
Angewandte Chemie International Edition in English, 1972AbstractThe purpose of this review is to present an up‐to‐date account of the chemistry of the metal ion in the enzyme carbonic anhydrase. The interest lies in how the study of the metal may lead to deductions concerning the chemistry of the enzyme's action and in the way that metalloenzyme chemistry seems to demand a new appraisal of some aspects of ...

Ion Deposited Carbon Coatings.
1983Abstract : The overall objective of this program is to demonstrate a system capable of reproducibly coating polycarbonate plastic sheet with ion deposited transparent carbon. The carbon coatings are to be characterized on the plastic sheet for potential use as a durable, abrasion resistant coating for windshield and canopy assemblies.

Strip injection for carbon ion synchrotrons
Review of Scientific Instruments, 2007Requirements and effects of strip injection of C4+ at 6MeV∕u into carbon ion synchrotrons are studied. The setup is composed of three chicane dipoles, one Lambertson septum, and one carbon stripping foil at a thickness of 60μg∕cm2. The required length of the injection section is about 4.1m.
