Dissymmetrical tunnelling in heavy fermion metals [PDF]
JETP Lett. 81, 222 (2005)., 2005 A tunnelling conductivity between a heavy fermion metal and a simple metallic point is considered. We show that at low temperatures this conductivity can be noticeably dissymmetrical with respect to the change of voltage bias.

Quasiparticles near quantum phase transition in heavy fermion metals [PDF]
Physica B 378-380, 127 (2006), 2005 We have shown that the Landau paradigm based upon both the quasiparticle concept and the notion of the order parameter can be used to explain the anomalous behavior of heavy fermion metals.

Iron (oxyhydr)oxides are responsible for the stabilization of Cu and Zn in AMD after treatment with limestone [PDF]
PeerJ, 2023 The formation and transformation of secondary iron (oxyhydr)oxides and their role in the stabilization of copper (Cu) and zinc (Zn) in acid mine drainage (AMD) after limestone treatment are worth studying to better understand the impacts of limestone AMD

Forest humus type governs heavy metal accumulation in specific organic matter fractions [PDF]
, 2020 Soils have the potential to accumulate heavy metals and the capacity to do so is strongly related the properties of each soil. Soil organic matter is a key factor in the retention, release, and bioavailability of heavy metals, and here we have determined
