(Iop Publishing Ltd, 2020)Motivated by the recent successful synthesis of double-M carbides, we investigate structural and electronic properties of WCrC and WCrCO2 monolayers and the effects of biaxial and out-of-plane strain and electric field ... -
ADSORPTION OF BOVINE SERUM ALBUMIN ONTO ACTIVATED CARBON PREPARED FROM ELAEAGNUS STONE
(Chem Soc Ethiopia, 2018)In this study, the adsorption of bovine serum albumin was studied using the activated carbon prepared from Elaeagnus stone with chemical activation. Elaeagnus stone activated carbon was characterized using the point of ... -
Dual curves associated with the Bonnet ruled surfaces
(World Scientific Publ Co Pte Ltd, 2020)An interest problem arises to determine the surfaces in the Euclidean three space, which admit at least one nontrivial isometry that preserves the principal curvatures. This leads to a class of surface known as a Bonnet ... -
Investigation of neutron and gamma radiation protective characteristics of synthesized quinoline derivatives
(Taylor & Francis Ltd, 2020)Purpose: Quinoline is formed by various natural compounds, such as alkaloids from the cinchona plant, which exhibit various biological activities, and is an important building material for the development of new drugs. ... -
Combating domestic violence in Turkey
(Editura Pro Universitaria Srl, 2016)The matters of preventing domestic violence against women and enabling gender equivalence have been discussed since the end of 1960s. The issue of violence against woman has stayed as an unspoken matter until recently in ... -
Boron doped graphene based linear dynamic range photodiode
(Elsevier Science Bv, 2018)The boron-doped graphene oxide film was prepared using drop casting/coating technique. The film was coated by hydrothermal method on p-Si substrate and thus Al/p-Si/B-doped GO/Au diode was fabricated. The structural ... -
Tunable electronic and magnetic properties of graphene/carbon-nitride van der Waals heterostructures
(Elsevier, 2020)In this paper, we explore the electronic properties of C3N, C3N4 and C4N3 and graphene (Gr) van der Waals heterostructures by conducing extensive first-principles calculations. The acquired results show that these ... -
AFM induced diffusion of large scale mobile HOPG defects
(Springer Heidelberg, 2019)Defects on crystal and/or thin film surfaces play an important role in their physical and chemical properties. Diffusion or motion of such structures results in microstructural dynamic changes. The diffusion of single ... -
Novel dendrimers containing redox mediator: Enzyme immobilization and applications
(Elsevier Science Bv, 2019)In this study, new dendrimers with a ferrocene core were produced by means of a divergent method for the immobilization of the glucose oxidase enzyme (GOx). Pt(II) and Pt(IV) ions were attached to the terminal groups of ... -
A TYCHONOFF THEOREM FOR GRADED DITOPOLOGICAL TEXTURE SPACES
(Ankara Univ, Fac Sci, 2020)In this paper, initial and product graded ditopologies are formulated and accordingly it is shown that dfGDitop is a topological structure over dffex x dffex. By means of spectrum idea, (di)compactness in graded ditological ... -
