The traditional separation of electrons in molecules into core and valence types is often based on molecular orbital energies. This method is known to lead in some cases to large relative errors in correlated calculations. Instead, we propose a method based on the definition of molecular core char...

The capture cross-sections for electrons and holes were assigned as 10−13 and 10−14 cm2 respectively. Unless specifically analyzing the impact of changing Nit, Nit was maintained at a fixed value of 1010 cm−2. To validate the robustness and accuracy of our simulation methodology, we ...
This effect arises from the lower refractive index of plasma due to the strong negative polarisability of free electrons. At sufficiently high pump intensities, plasma formation occurs very rapidly around the temporal peak of a soliton, leading to a fast drop of the refractive index, and ...

The main 3𝑑3d peak, 8, which includes the 3𝑑3d(i) contribution, systematically shifts to larger BEs if the symmetry is lowered, since more electron density at the (i)-side makes the 3𝑑3d(i)-electrons less strongly bound. Pulling the ionic iodine away from the other two, the ...
which reduces the polarization electric field and provokes the flow of electrons. Thus, the overall electric output of the composite nanofibers is readily enhanced. For the mentioned reasons, it is important to reduce the resistance in a wearable nanogenerator. The electrical resistance of the device...
The term “El/2” refers to the practical definition of the formal potential (E°) of a redox process as defined by E1/2=E°+(RT/nF)ln(Dox/Dred) where R is the gas constant, T is temperature in K (Kelvin), n is the number of electrons involved in the process, F is the Farad...
This biosensor can exchange electrons between the enzymes and the electrode without a mediator. The lack of need for mediators in this type of glucose biosensor has increased selectivity [16]. Enzyme biosensors are commercially successful bioanalytical devices that display high sensitivity and selectivity...
This core radius is simply related to a number of physical parameters; the value of the wave vector at which the form factor of the model potential first reaches zero, the radius of the atom in the solid, the interelectron spacing of the conduction electrons, the De Bye temperature, and ...
