Spacetimes admitting the Z-symmetric tensor
(Natl Inquiry Services Centre Pty Ltd, 2020)
This paper aims to introduce the spacetimes admitting the Z-symmetric tensor. We investigate the properties of these spacetimes for a perfect fluid and a pressureless perfect fluid (a dust). Some theorems about the properties ...
Electrical, optical, and mechanical percolations of multi-walled carbon nanotube and carbon mesoporous-doped polystyrene composites
(Sage Publications Ltd, 2020)
In this study, we have investigated and compared electrical, optical, and mechanical properties of polystyrene thin films with added multi-walled carbon nanotube and carbon mesoporous. Surface conductivity (sigma), scattered ...
Fractal dimension and phase transition of graphene oxide (GO) doped polyacrylamide
(Elsevier Sci Ltd, 2020)
Graphene Oxide (GO)- Polyacrylamide composites prepared between 5 and 50 mu l GO were performed by Fluorescence Spectroscopy. The phase transition performed on the composites was measured by calculating the critical ...
Electrical, optical and mechanical properties of chitosan biocomposites
(Sage Publications Ltd, 2020)
In this work, chitosan/graphene nanoplatelets (CS/GNP) and chitosan/multi-walled carbon nanotube (CS/MWCNT) biocomposite films were prepared using a simple, eco-friendly and low-cost method. The electrical, optical and ...
Electrical, mechanical, and optical changes in MWCNT-doped PMMA composite films
(Sage Publications Ltd, 2020)
In this study, we report the preparation of poly (methyl methacrylate)/multi-walled carbon nanotube (MWCNT) composite thin films by simple and efficient solution mixing and ultrasonic method and the electrical, optical, ...
Poly(azomethine-imide)s containing siloxane moities: Optical, thermal, mechanical, and morphological properties
(Wiley, 2020)
A new series of poly(azomethine-imide)s having siloxane moities in backbone was prepared using different dianhydrides.Thermal, optical, and morphological properties of these polymers were clarified. Also, bulky Symbol of ...
Antibacterial nano cerium oxide/chitosan/cellulose acetate composite films as potential wound dressing
(Pergamon-Elsevier Science Ltd, 2020)
Novel chitosan and cellulose acetate polymer composites with nanosized cerium oxide were prepared as potential wound dressing materials. Chitosan and cellulose acetate are natural polymer derivatives with biocompatible ...
An overview of wire arc additive manufacturing (WAAM) in shipbuilding industry
(Taylor & Francis Ltd, 2020)
Increasing competition in the international shipbuilding industry pushes the naval architect's pressure to reduce the costs of design and manufacturing of new buildings. Using newly developed Additive Manufacturing (AM) ...
Production and characterization of recycled polyester (r-PET) blend vortex and ring spun yarns
(Taylor & Francis Ltd, 2020)
Nowadays, many major fashion brands are now producing recycled polyester (r-PET) textile products from PET bottles to contribute to sustainability. Of course, this means that textiles containing r-PET will now be produced ...
Predicting air permeability and porosity of nonwovens with image processing and artificial intelligence methods
(Taylor & Francis Ltd, 2020)
This study was conducted to investigate the relationship between the fiber distribution and the permeability properties of the hydroentangled nonwoven fabrics in terms of air permeability and porosity. The fiber distribution ...
