Effect of Nano Clay and Marble Powder Waste as a Hybrid Addition on the Behavior of Normal and High Strength RC Columns Subjected to Axial Compressive Loading

by Mostafa Ahmed Mahdi, Ahmed Hassan Ghallab, El-Saaid Ibrahim Zaki and Ahmed Sayed Elmannaey

Advances in Science, Technology and Engineering Systems Journal, Volume 6, Issue 3, Page # 367–384, 2021; DOI: 10.25046/aj060343

Abstract:

This paper studied the influence of using hybrid additives of Nano Clay (NC) and Marble Powder (MP) on the structural behavior of columns, in terms of ultimate capacity, axial strain, lateral strain, toughness, and failure pattern. For this purpose, ten column specimens were made from reinforced concrete (RC), either normal or high strength, and were…

Johnson Noise and Optical Characteristics of Polymer Nanocomposites Based on Colloidal Quantum Dots and In-Situ Nanoparticles Formation

by Fatin Hana Naning, S. Malik, Lee Feng Koo, Tze Jin Wong and Pang Hung Yiu

Advances in Science, Technology and Engineering Systems Journal, Volume 5, Issue 5, Page # 750–756, 2020; DOI: 10.25046/aj050591

Abstract:

Electrical and optical properties of polymer nanocomposite thin films have been analyzed to study their reliability and competency as a component for optoelectronic devices such as LED and solar cells. Polymer nanocomposite encounters various challenges, such as the dispersion of nanoparticles in the matrix that hinders their efficiency for potential devices. In this paper, two…
