An In Vitro Corrosion Study of Open Cell Iron Structures with PEG Coating for Bone Replacement Applications
(MDPI, 2018-06-28)
Iron-based substrates with polyethylene glycol coating were prepared as possible materials for biodegradable orthopedic implants. Biodegradable materials that provide mechanical support of the diseased tissue at the time ...
Methods for recycling photovoltaic modules and their impact on environment and raw material extraction
(Acta Montanistica Slovaca, 2017-12-11)
This work deals with methods of recycling of photovoltaic modules and evaluates contribution of recycling to the environment and reduction of raw materials extraction. The article describes the materials needed to manufacture ...
Sodno-iontové akumulátory - budoucnost a aktuální vývoj

Aby bylo možné používat olověných akumulátorů v mimořádně obtížných podmínkách v těžebním průmyslu, je velmi důležité pochopit děje, ke kterým dochází při trakčním provozu těžebních vozíků nebo při používání pomocného ...
Improved Electrochemical Performance of NCM Cathode Materials Based on the Modification of the Salt Content in the Electrolyte
(IOP Publishing, 2019-11-25)
In this work, NCM cathode materials, for Li-ion batteries, were synthesized via a solid-state reaction routine, in which manganese (IV) dioxide, nickel (II) oxide, cobalt (II) hydroxide and lithium hydroxide monohydrate ...
The Effect of a Spiral Gradient Magnetic Field on the Ionic Conductivity of Water
(MDPI, 2017-09-02)
We discuss the experimental verification of changes in the structure of a liquid water sample inserted in a special spiral “gradient” magnetic field. The magnetic flux components are characterized by a high degree of ...
Characterization of the Embryogenic Tissue of the Norway Spruce Including a Transition Layer between the Tissue and the Culture Medium by Magnetic Resonance Imaging
(De Gruyter Open, 2017-02-25)
The paper describes the visualization of the cells (ESEs) and mucilage (ECMSN) in an embryogenic tissue via magnetic resonance imaging (MRI) relaxometry measurement combined with the subsequent multi-parametric segmentation. ...
Low-frequency noise measurements used for quality assessment of GaSb based laser diodes prepared by molecular beam epitaxy
(Faculty of Electrical Engineering and Information Technology of the Slovak University of Technology, 2015-08-01)
The paper reports on a non-destructive method of reliability prediction for semiconductor lasers diodes GaSb based VCSE. Transport and noise characteristic of forward biased were measured in order to evaluate the new MBE ...
