Improving Biocompatibility of Co-Cr Alloy Used in Dentistry by Surface Modification with Electrochemical methods-Corrosion of Untreated Co-Cr Alloy in Solution with Different pH
(Universitatea 'Dunărea de Jos" din Galați, 2014)
The use of metals and alloys in dentistry has seen remarkable progress due to
the deep research on their biocompatibility or the application of advanced
technologies to improve surface properties by controlling ...
Effective Electromechanical Coupling for the Partially Electroded Ceramic Resonators of Different Geometries
(Universitatea "Dunărea de Jos" din Galați, 2015)
Effective electromechanical coupling factor (ECF) was studied on bar, disc
and ring ceramic resonators partially covered by electrodes. ECFs were calculated
theoretically and verified experimentally. Bar resonators ...
Detailed Microcontroller Architecture Based on a Hardware Scheduler Engine and independent Pipeline Registers
(Universitatea "Dunărea de Jos" din Galați, 2015)
In the world of real time operating systems, task switching, communication
between threads and synchronization are implemented in software. Some of the
mechanisms used may introduce big latencies in task recurrence, task ...
Conductive-Atomic Force Microscopy Investigation of the Electrical Properties of Low Temperature Deposed ZnO Transparent thin Films
(Universitatea "Dunărea de Jos" din Galați, 2015)
The paper presents the investigation by conductive-atomic force microscopy
(C-AFM) of the variation of the local conductivity and topography of the
transparent ZnO thin films deposed onto soda lima glass substrates by ...
Determination of Glass Transition Temperature for Polyester/Graphene Oxide and Polyester/Graphite Composite by TMA and DSC
(Universitatea "Dunărea de Jos" din Galați, 2015)
The influences of oxide grapheme and grapheme in thermosetting polymer
composites are complex and they very much depend on the chemical bonds formed
between the additives and the polymer matrix. This study has used ...
Selective Recovery by solubilization of Metals Ions of Chromium, Iron and Zinc from Electroplating Sludge to Develop Pigments for Ceramics Industry
(Universitatea 'Dunărea de Jos" din Galați, 2015)
Electroplating industries discharge large amounts of heavy metals, including
chromium (Cr), iron (Fe) and zinc (Zn) ions, in the wastewater resulted from
technological processes, as well as in the sludge from wastewater ...
The Electromagnetic Proprieties of Hybrid Composites
(Universitatea "Dunărea de Jos" din Galați, 2015)
This research investigates the electromagnetic behaviour of hybrid composites
with heterogeneous epoxy matrix. The hybrid composites were formed by the wet
lay-up method and were made of three types of simple plain fabrics ...
Applications Based on Variabile Frequency Rotating Magnetic Field Electromechanical Agitator With Dual Direction
(Universitatea "Dunărea de Jos" din Galați, 2015)
This paper presents a series of experimental results obtained by studying the
specific effects and phenomena of the rotating magnetic field. During the research,
an interesting phenomenon, specific to the variable frequency ...

In this paper the authors have done a characterization of the electrical
properties of vinyl ester based nanocomposites containing different percentages of
carbon nanomaterials
The carbon fillers used in this study were ...
The Importance of Using Membranes in Seawater Desalination as a Result of Excessive Exploitation of Water Sources
(Universitatea "Dunărea de Jos" din Galați, 2017)
This paper is a detailed study of the need to find and implement new solutions
for water filtration and the promotion of modern techniques that are more effective
than traditional methods. As a result of extension waste ...
