Synthesis and characterization of AgPd alloy coatings as beneficial catalysts for low temperature fuel cells application
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
The Ag, Pd and AgPd alloys of different morphologies and compositions were electrodeposited onto Au and glassy carbon (GC) disc electrodes from the solution containing 0.001 M PdCl2 + 0.04 M AgCl + 0.1 M HCl + 12 M LiCl ...
Ab Initio Study of the Electronic, Vibrational, and Mechanical Properties of the Magnesium Diboride Monolayer
(MDPI, Basel, 2019)
Magnesium diboride gained significant interest in the materials science community after the discovery of its superconductivity, with an unusually high critical temperature of 39 K. Many aspects of the electronic properties ...
Silicon alleviates copper (Cu) toxicity in cucumber by increased Cu-binding capacity
(Springer, Dordrecht, 2019)
Aims Although silicon (Si) is known to increase plant resistance to metal toxicity stress, the mechanisms responsible for alleviation of copper (Cu) toxicity are still insufficiently clear. We investigated the role of Si ...
Structure and Magnetic Properties of (Ni1- Zn-x(x))Fe2O4 Ceramics with a Spatial Change in the Composition
(Pleiades Publishing Inc, Moscow, 2019)
Samples of homogeneous (x = 0, 0.1, and 0.2) and multilayer ceramics based on solid solutions of nickel-zinc ferrites (Ni1 - Zn-x(x))Fe2O4 with a "contrary" composition gradient (x = 0.2 -> 0 -> 0.2) have been prepared by ...
