Abstract In this paper, a latent infection susceptible–exposed–infectious–recovered model with demographic effects is used to understand the dynamics of the COVID-19 pandemics. We calculate the basic reproduction number ( $${R}_{0}$$ R 0 ) by s

The heavy rare-earth GdFeO3-type RFeO3 (R = Dy, Ho and Er) orthoferrites (space group Pnma, N 62) show spin reorientation transition characterized by a turning point on the magnetization curves. The basic Arrott plots curves showing positive slopes c

Experiments for heavy rare-earth iron garnets Ho3Fe5O12 and Er3Fe5O12 show a compensation effect characterized by a near zero magnetization at 134 K and 80 K, respectively. The magnetic entropy change calculated according to the Maxwell's relation is

Obtaining tunable magnetic states in geometrically frustrated multiferroic compound CoCr2O4 by tuning the sublattice magnetic coupling is indeed of high interest from the fundamental and applied points of view. In this work, Fe substitution effects i

Structural and magnetic properties were studied in a series of single-phased polycrystalline EuCr1-xFexO3 (0 ≤ x ≤ 0.6) ceramic samples which were successfully synthesized by Pechini method. The dc magnetic measurements revealed that Fe-doping in

Electrochemical carbon dioxide (CO2) reduction into valuable chemicals is usually implemented at high overpotential, and most bimetallic catalysts suffer from the dramatic evolution of surface composition especially in case of long-term operation. In
