Matrix resistance stress: A key parameter for immobilized cell growth regulation
(Elsevier Sci Ltd, Oxford, 2017)
Microenvironmentally restricted yeast cell growth within Ca-alginate beads with and without entrapped gas bubbles was considered based on experimental data. Cell growth dynamics was described by (1) the dimensionless cell ...
Antifungal activity of the onion (allium cepa l.) Essential oil against aspergillus, fusarium and penicillium species isolated from food
(Wiley, Hoboken, 2017)
The aim of this study was to investigate the antifungal potential of onion (Allium cepa L. cultivar Kupusinski jabuar) essential oil against fungal species isolated from food. Twenty one compounds were identified in the ...
Absorption boost of TiO2 nanotubes by doping with N and sensitization with CdS quantum dots
(Elsevier Sci Ltd, Oxford, 2017)
A process of obtaining N-doped TiO2 nanotubes sensitized by CdS nanoparticles is presented, including detailed characterizations performed along the synthesis. Transparent TiO2 films consisting of nanotubes, 2.5 mu m long ...
Nanomechanical and anti-stabbing properties of Kolon fabric composites reinforced with hybrid nanoparticles
(Elsevier Sci Ltd, Oxford, 2017)
In this study carbon nanotubes (CNT) and silica nanoparticles (SiO2) were added to enhance the dynamic mechanical and anti-stabbing properties of the polyurethaneip-aramid multiaxial fabric (Kolon fabric) composites for ...
Separation of phytochemicals from Helichrysum italicum: An analysis of different isolation techniques and biological activity of prepared extracts
(Pergamon-Elsevier Science Ltd, Oxford, 2017)
Helichrysum italicum presents a valuable source of natural bioactive compounds. In this work, a literature review of terpenes, phenolic compounds, and other less common phytochemicals from H. italicum with regard to ...
Step-controlled Brownian motion of nanosized liquid Pb inclusions in a solid Al matrix
(Pergamon-Elsevier Science Ltd, Oxford, 2017)
We have made direct observations of the Brownian motion of individual nanosized liquid lead inclusions in solid aluminum by in-situ transmission electron microscopy. The process was found to depend strongly on the size of ...
Melt Extrudate Swell Behavior of Multi-Walled Carbon Nanotubes Filled-Polypropylene Composites
(Wiley, Hoboken, 2017)
The extrudate swell behavior of polypropylene (PP) composite melts filled with multi-walled carbon nanotubes (MWCNTs) was studied using a capillary rheometer in a temperature range from 190 to 230 degrees C and at various ...
Structural Properties of the Multiwall Carbon Nanotubes/Poly(Methyl Methacrylate) Nanocomposites: Effect of the Multiwall Carbon Nanotubes Covalent Functionalization
(Wiley, Hoboken, 2017)
The structural characteristics of polymer nanocomposites with functionalized multiwall carbon nanotubes (MWCNTs) in poly(methyl methacrylate) matrix have been studied in relation to nanofiller loading and surface functionality. ...
Simultaneous enhancement of natural sunlightand artificial UV-driven photocatalytic activity of a mechanically activated ZnO/SnO2 composite
(Royal Soc Chemistry, Cambridge, 2017)
Mechanical milling of commercial ZnO and SnO2 was used to produce a ZnO/SnO2 composite with a high density of surface defects; in particular, zinc interstitials (Zni) and oxygen vacancies (VO). To determine the impact of ...
Optimization of the process of Cu(II) sorption by mechanically treated Prunus persica L. - Contribution to sustainability in food processing industry
(Elsevier Sci Ltd, Oxford, 2017)
This paper presents an eco-friendly approach for minimizing heavy metal pollution, offering food waste valorization and energy source at the same time. It focuses on Cu(II) sorption by low cost sorbent developed by mechanical ...
