Structurally and surface-modified alumina particles as a reinforcement in polyester-based composites with an improved toughness
(Springer, New York, 2020)
Commercial gamma - Al2O3 particles, Al2O3 n, and synthesized Al2O3 doped with iron oxide (Al2O3 Fe) were used as reinforcements to enhance the toughness of an unsaturated polyester resin (UPR). Alumina modification with ...
Antibacterial activity of metal-containing clinoptilolite in natural seawater
(Desalination Publ, Hopkinton, 2019)
Antibacterial activity of a natural zeolite, clinoptilolite (Z), enriched with about 0.4-0.5 mmol of Ag (Ag-Z), Cu (Cu-Z) or Zn (Zn-Z) was tested toward two strains of Gram-negative bacteria - Escherichia coli and Acinetobacter ...

(John Wiley and Sons Inc, 2019)
Purpose: To investigate with Doppler ultrasonography the maxillary and middle meningeal arteries in the infratemporal fossa, and describe their hemodynamic characteristics. Methods: We included 24 female and 11 male ...
Experimental Investigation of Microstructure and Phase Transitions in Ag-Cu-Zn Brazing Alloys
(Springer, 2018)
Microstructure and phase transitions of selected brazing alloys from the Ag-Cu-Zn ternary system were investigated. Four ternary alloys with silver content in the compositional range from 25 to 60 wt.% were studied using ...
A Spontaneous Cervical Epidural Hematoma Mimicking a Stroke: A Challenging Case
(Elsevier USA, 2019)
Background: A spontaneous cervical epidural hematoma (SCEH) is a rare occurrence, with < 500 cases reported to date. Clinically, it usually presents with quadriparesis, but in extremely rare cases it can present with ...

Characterisation of biomedical titanium layers deposited by a vacuum plasma spray process
(Materiali in Tehnologije, 2021)
In this paper we will describe the process of the deposition of thick layers of VPS-Ti coating, which is used as a bonding layer for the upper porous Ti coatings on implant substrates. In order to deposit the powder, we ...
The effect of CaO and MgO addition and cooling rate on stability of slag obtained after jarosite and neutral leaching residue treatment in the Waelz process
(Oficyna Wydawnicza Politechniki Wroclawskiej, Wroclaw, 2018)
Jarosite and neutral leaching residue (NLR) are the greatest environmental problems of hydrometallurgical zinc production due to their high quantity and hazardous content. Pyrometallurgical processes, such as the Waelz ...
