The Montgomery method is extensively employed to determine the electrical resistance tensor of anisotropic samples. This technique relies on two essential parameters describing an isotropic system: the geometric factor (H1) and the effective thicknes

Dissolved oxygen (DO) is an essential parameter of water quality, and the surface reaeration process (K2) is the main source of DO in aquatic ecosystems. On a laboratory scale, reaeration measurements are performed using water-stirring setups (WSSs),

In this paper, a comprehensive study of the effects of Ni-doping on structural, electrical, thermal and magnetic properties of the NbB2 is presented. Low amounts (\leq 10 %) of Ni substitution on Nb sites cause structural distortions and induce drast

MoO y with 1.85 ≤ y ≤ 2.20 has been studied by X-ray diffractometry and photoemission spectroscopy at room temperature and by electrical resistance as a function of temperature from 2 to 300 K. Although X-ray diffractograms are very similar to th
