Charged-Molecule Physics

ACS Nano, 2014
Commonly, chemical modification is considered to be the ultimate way to tune properties of graphene for new devices. The work of Riss and colleagues reported in this issue of ACS Nano demonstrates a reverse approach that enables tuning of molecular properties with graphene.

Physical Charged Sectors in Quantum Electrodynamics. II. The Charge Operator

Fortschritte der Physik, 1984
AbstractThe properties of Maxwell type equations and the related problem of approximation of physical charged states are studied in the framework of axiomatic gauge quantum field theory. The charge operator and the physical charged sectors of quantum electrodynamics are constructed under a set of hypotheses which can be verified in perturbation theory ...

Overcharging, charge reversal: Chemistry or physics?

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2006
Abstract Overcharging, also called charge reversal or charge inversion, is the occurrence of electric double layers in which, as measured by electrokinetics or interaction, there is more countercharge than charge on the surface. The trend is that the propensity of overcharging increases with the valency of the counterion.

Physical look at vacuum fermionic charge

Physical Review D, 1987
Using general principles, we present a simple physical derivation of the formula for the induced vacuum charge in 1+1 dimensions, and give some criteria for the dependence of that charge on the details of the background-field configuration.

Is gravitational dual charge physical?

International Journal of Theoretical Physics, 1977
It has been shown that nonzero gravitational dual charge cannot be found in a spinmanifold space-time. Nevertheless, gravitational dual charge is not physically inconsistent with spin-1/2, because spinor nodal regions should be excluded from the manifold.

Physics hypercumulation and comdined shaped charges

2012 IEEE 11th International Conference on Actual Problems of Electronics Instrument Engineering (APEIE), 2012
The novel points of view to the formation of shaped charge jets are described. The physics of so-called hypercumulation are described in details and confirmed by numerical simulations. It has been shown that hypercumulation effects allow to increase both the speed and mass of a cumulative jets much more than the theory by Lavrentyev-Birkhoff predict ...

Charged Particle Therapy: The Physics of Interaction

The Cancer Journal, 2009
Particle therapy has a long and distinguished history with more than 50,000 patients having been treated, mainly with high-energy proton therapy. Particularly, for proton therapy, there is an increasing interest in exploiting the physical characteristics of charged particles for further improving the potential of radiation therapy.
