Journal ArticleDOI
Recent advances in 3D printing of porous ceramics: A review
TL;DR: In this paper, 3D printing technology is evaluated for its compatibility with porous ceramic materials, due to its competitive process in terms of speed and specific tooling, especially for good quality fabrication.
Journal ArticleDOI
A Review on the Pharmacological Activities and Phytochemicals of Alpinia officinarum (Galangal) Extracts Derived from Bioassay-Guided Fractionation and Isolation.
TL;DR: This review summarizes the phytochemical and pharmacological properties of the extracts and fractions from A. officinarum, a plant species of the Zingiberaceae family, and studies their biological activities – antioxidant, antibacterial, anti-inflammatory, anticancer, antiproliferative, inhibition of enzymes, as well as the inhibition of nitric oxide production.
Journal ArticleDOI
Chemical composition, antioxidant and antimicrobial activities of essential oils from leaves, aerial stems, basal stems, and rhizomes of Etlingera fimbriobracteata (K.Schum.) R.M.Sm.
A.F.M. Shahid Ud-Daula,Fatih Demirci,Kamariah Abu Salim,Betül Demirci,Linda B.L. Lim,Kemal Hüsnü Can Başer,Norhayati Ahmad +6 more
TL;DR: Schum et al. as mentioned in this paper analyzed essential oils from the leaves, aerial stems, basal stems, and rhizomes of Etlingera fimbriobracteata (K.Schum.) R.Sm.
Journal ArticleDOI
Properties of Si3N4–TiN composites fabricated by spark plasma sintering by using a mixture of Si3N4 and Ti powders
TL;DR: In this paper, the sintering mechanism for SPS was a hybrid of dissolution-reprecipitation and viscous flow, and the electrical resistivity decreased with an increasing SPS temperature up to a minimum at 1250-1350°C and then increased with the increasing Sintering temperature.
Journal ArticleDOI
Microstructural evaluation of a slurry based Ni/YSZ thermal barrier coating for automotive turbocharger turbine application
Muhammad Rabiu Abbas,Muhammad Rabiu Abbas,M.B. Uday,Alias Mohd Noor,Norhayati Ahmad,Srithar Rajoo +5 more
TL;DR: In this paper, a slurry-based coating method was used for the fabrication of functionally graded thermal barrier coating (FG-TBC) for turbocharger application in order to minimize the production cost of ceramic thermal barrier coatings.
