Diaphragm shear strength and stiffness of aluminum roof panel assemblies
( Elsevier Ltd , 2016 , Article)A diaphragm is an assembly of planar structural elements interconnected to each other to provide in-plane bracing system and transmit in-plane forces. The diaphragm geometry, supporting frame, type of the panel profiles, ... -
Diatomite chemical activation for effective adsorption of methylene blue dye from model textile wastewater
( International Journal of Environmental Science and Development , 2021 , Article)Dye wastewater produced in textile industries is a warning issue that threatens the environment due to discharge into the waterway. This study reviewed the adsorption of Methylene Blue (MB), as a toxic dye, onto diatomite ... -
Dicarbonyl stress, protein glycation and the unfolded protein response
( Springer , 2021 , Article Review)The reactive dicarbonyl metabolite, methylglyoxal (MG), is increased in obesity and diabetes and is implicated in the development of insulin resistance, type 2 diabetes mellitus and vascular complications of diabetes. ... -

Dielectric and electromagnetic interference shielding properties of germanium dioxide nanoparticle reinforced poly(vinyl chloride) and poly(methylmethacrylate) blend nanocomposites
( Springer New York LLC , 2018 , Article)Germanium dioxide (GeO2) nanoparticles reinforced poly(vinyl chloride) (PVC) and poly(methyl methacrylate) (PMMA) blend nanocomposite films were prepared using solution casting technique. The PVC/PMMA/GeO2 nanocomposite ... -
Dielectric properties of Mn doped Bismuth Barium Titanate based ceramic thin films prepared by PLD technique
( Elsevier Ltd , 2017 , Article)In this article, the effect of Mn doping on the permittivity and dielectric loss in 0.67BiFeO3-0.33BaTiO3 (BF-BT) based film bulk acoustic resonator test structures has been investigated. BF-BT thin films were deposited ... -
Dielectric properties of polyvinyl alcohol (PVA) nanocomposites filled with green synthesized zinc sulphide (ZnS) nanoparticles
( Springer New York LLC , 2019 , Article)In this study, zinc sulphide nanoparticles (ZnS NPs) have been synthesized by green synthesis approach. These ZnS NPs were used as nanofiller to fabricate polyvinyl alcohol (PVA) based nanocomposite films via solution ... -
Dielectric sensitization of zeolitic imidazolate framework-8 (ZIF-8) nanopowder.
( Academy of Sciences and Arts of the Republic of Srpska , 2017 , Article)Metallo-organic complexes are a class of materials that are increasingly used in sensory applications. Zeolitic imidazolate frameworks (ZIFs) are their subclass that are topologically isomorphic with zeolites. The porosity ... -
Dielectric Spectroscopy
( Elsevier , 2017 , Book chapter)In this chapter, an attempt has been made to review dielectric spectroscopy (DS) as a technique for the characterization of nanomaterials. DS involves the study of the response of a material to an electric field, which ... -
Diesel-fired boiler performance and emissions measurements using a combination of diesel and palm biodiesel
( Elsevier Ltd , 2021 , Article)Biodiesel is widely accepted as a fuel that is similar to diesel with various advantages. Biodiesel's low-temperature flow qualities are one of its characteristics that limits its use. The goal of this study was to see how ... -
