Magnetic nanoparticles (MNPs) have emerged as efficient materials for thermo-therapeutic modalities viz. magnetic fluid hyperthermia (MFH) and photo-thermal therapy (PTT). Nevertheless, the quest to further enhance the ...

In the present paper, a dual frequency resonance antenna is achieved by introducing half U-shaped slot in semicircular disk. It is analysed by using circuit theory concept. The resonance frequency is found to be 1.50 GHz ...

Rifabutin loaded floating gellan gum beads were prepared by ionotropic gelation in acidic medium. Buoyancy to the beads was attributed to the use of gas-generating agent, which produced an extremely porous internal structure ...

A problem of propagation of strong plane and converging shock wave is studied in a mixture of a gas and small solid particles. It is assumed that the solid particles are continuously distributed in the gas. Jump conditions ...

Using kinetic Monte Carlo simulations, we study the effect of oscillatory kinetics due to surface reconstructions on Ziff-Gulari-Barshad (ZGB) model discontinuous phase transition. To investigate the transition, we do ...

Chitosan has become a focus of major interest in recent years due to its excellent biocompatibility, biodegradability and non-toxicity. Although this material has already been extensively investigated in the design of ...

Alloys of Fe-Si-B with varying compositions of Mn were prepared using high energy planetary ball mill for maximum duration of 120 h. X-ray diffraction (XRD) analysis suggests that Si gets mostly dissolved into Fe after 80 ...

Pitch-angle diffusion coefficients have been calculated for resonant interaction with electrostatic electron cyclotron harmonic (ECH) waves in the magnetospheres of Earth, Jupiter, Saturn, Uranus and Neptune. Calculations ...

We study the intensity oscillations in the upper chromosphere/transition region (TR) and corona, above a bright point (BP) in the solar atmosphere. We analyse the time series of He ii 256 Å, Fe xii 195 Å and Fe xv 284 Å, ...

In this paper, the axi-symmetric peristaltic transport of a viscous incompressible visco-elastic fluid has been investigated through a circular tube whose cross section changes along the length. The wall motion is governed ...
