Large amplitude dust ion acoustic solitons: considering dust polarity and nonextensive electrons

The characteristics of arbitrary amplitude dust ion acoustic solitary waves (DIASWs) are studied in unmagnetized dusty plasmas whose constituents are cold uid ions, nonextensive electrons and stationary negative/positive dust particles. The pseudopotential approach has been used to investigate the structure of localized waves. It is found that, solitary waves exist in a definite interval for th...

Quantum transistors : toward nanoelectronics Electrons that tunnel through insulating barriers and hop on and off

Nanoelectronics: Making light of electrons.

Electrons have been channelled through graphene wires using the principles of optical guiding by fibre optic cables.

How the surrounding water changes the electronic and magnetic properties of DNA.

We study the influence of humidity on the transport and magnetic properties of DNA within the quantum chemistry methods. Strong influence of water molecules on these properties, observed in this study, opens up opportunities for application of DNA in molecular electronics. Interaction of the nucleobases with water molecules leads to breaking of some of the pi bonds and appearance of unbound pi ...

خواص ساختاری و الکترونی بلور سریم حاصل از محاسباتLDA+U

 In this work structural, electronic and magnetic properties of alpha and gamma phases of cerium crystal have been calculated by means of the LDA and LDA+U methods. The equilibrium volume and magnetic moment obtained from the GGA approximation in agreement with the experiment are equal to 27.64 Å3 and 0.00018 µB, respectively. This agreement shows that the 4f electrons in alpha phase are itiner...
