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 ...
Sodno-iontové akumulátory - budoucnost a aktuální vývoj
(NZEE, 2019-05-15)
The lithium-ion technology is widely known and spread technology. The based of this technology lies on transport of lithium ions during charging or discharging from one electrode to the other, this principle is call “rocking ...

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. ...
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 ...
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 ...
Supercapacitors: Properties and applications
(Elsevier, 2018-03-26)
Energy accumulation and storage is one of the most important topics in our times. This paper presents the topic
of supercapacitors (SC) as energy storage devices. Supercapacitors represent the alternative to common ...
Redox and optically active carbohelicene layers prepared by potentiodynamic polymerization
(Elsevier, 2020-02-19)
This short paper describes the preparation of thin layers based on carbohelicenes, which are inherently chiral polyaromatics existing in the enantiomeric forms P and M. Specifically, [5]-, [6]- and [7]helicene were subjected ...
Availability of Suitable Raw Materials Determining the Prospect for Energy Storage Systems Based on Redox Flow Batteries
(Faculty of Mining, Ecology, Process Control and Geotechnologies (FBERG), Technical University of Kosice, 2018-04-30)
Successful large-scale deployment and manufacturing of newly designed products depends on the availability of raw materials and therefore even fundamental research on electrochemical energy sources cannot ignore the need ...
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 ...
