Carbenium ion formation by fragmentation of electrochemically generated oxonium ions
Organic & Biomolecular Chemistry, 2018Fragmentation of electrochemically generated oxonium ions can be exploited to form carbenium ions at a low oxidation potential in the presence of a nucleophile such as allylsilane.

It has to be expected that both ions and electrons will damage specimens under examination to a greater or lesser degree. Electrons are low in mass but can travel at velocities which are a significant fraction of the speed of light. In general, electrons do not significantly damage metallic or inorganic specimens, but even relatively low doses of ...

Physics World, 2004
When high-temperature superconductors were discovered in 1986, many physicists made wild claims that these materials would immediately transform the power, transport and communication industries. Although no such revolution has yet happened, the number of applications is rapidly growing.

What Ion Is Generated When Ionizing Acetonitrile?
The Journal of Physical Chemistry A, 2005It has long been assumed that ionizing neutral acetonitrile produces ions with the same atomic connectivity, CH(3)CN(+*). Recent calculations on the C(2)H(3)N(+*) potential energy surface have suggested that it may be difficult to generate pure CH(3)CN(+*) when ionizing acetonitrile.

Ion Channels in Action Potential Generation
Hospital Practice, 1992Molecular structure-function studies have identified the two key regions--the voltage sensor and pore--of the sodium and potassium channels responsible for the action potential in nerve axon. Mutational analysis has focused on the amino acids that are most important in each region. Similar studies in myocytes and nerve cell bodies are now being pursued.

Recent Advances in Aqueous Zinc-Ion Batteries
ACS Energy Letters, 2018Although current high-energy-density lithium-ion batteries (LIBs) have taken over the commercial rechargeable battery market, increasing concerns about limited lithium resources, high cost, and insecurity of organic electrolyte scale-up limit their ...

Pulse generator for ion implantation
Digest of Technical Papers. 11th IEEE International Pulsed Power Conference (Cat. No.97CH36127), 2002Plasma source ion implantation (PSII) requires a high-power pulse generator (megawatts average power and peak pulse power of over 5 MVA) that is efficient, very reliable and robust. The robustness is required because plasma arcs, spits and sputters.

Particle generation in ion implanters
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1995Abstract Optical elements at potential represent a serious concern for particle generation in ion implanters. Conditioning of acceleration columns is a well known phenomenon in accelerators but less well known is the fact that the microdischarging, which accompanies the conditioning process, results in high particle production.
