Electron spin resonance (ESR), called also electron paramagnetic resonance (EPR) together with the spin trapping technique, has allowed us to study and understand how free radicals are involved in various pathologies. In this review, the importance of spin trapping technique in the study of diseases such as cancer, diabetes, hypertension and parasitic diseases is discussed. In addition, advance...

We study spin-dependent transport in a suspended carbon nanotube quantum dot in contact with two ferromagnetic leads and with the dot’s spin coupled to the flexural modes. We consider a spinvibrational interaction inducing spin-flip processes between the two Zeeman levels of the dot due to spin-orbit interaction or a magnetic field gradient. The inelastic vibration-assisted spin-flips give rise...

As the data writing scheme of magnetization reversal driven by spin-transfer torque can overcome shortcomings traditional magnetic-field mechanism, it has become a mainstream way implementing information in magnetic random access memory. However, explosive growth shows higher requirements for storage and processing, thus memories based on method pose several issues, including barrier reliabilit...

Abstract The effect of CdS/ZnS composite-sensitized TiO 2 nanotube array (TNTA) on the photocatalytic reduction CO was studied. quantum dots sensitized TNTA by successive ionic layer adsorption and reaction (SILAR) cycle method, CdS/ZnS-TNTA composite semiconductor materials were prepared. loading amount depends number SILAR cycles. effects times, volume flow, light intensity performance main p...

We report an inexpensive TiO2 based quantum dot solar cell (QDSSC) with improved power conversion efficiency prepared by simple techniques. Barium doped zinc sulfide has been successfully deposited on cadmium dots (QDs) successive ion layer adsorption and reaction (SILAR) technique. The is utilized as a passivation in the QDSSC, which helped better charge separation. copper (Cu2S) reduced graph...

in this paper, we study the electronic properties of a concentric triple quantum ring using exact diagonalization technique. the energy spectra and magnetization for a single electron and two electrons, in the presence of an applied magnetic field, are calculated and discussed. it is shown that, for two-interacting electrons, the period of aharonov-bohm oscillations decreases to the half of tha...
