Linear and nonlinear optical properties of a superlattice with periodically increased well width under electric and magnetic fields
(Elsevier, 14.04.2022)In this paper, we have studied the electronic and optical properties of GaAs/AlxGa1-xAs superlattice with periodically increased well width. Under effective mass approximation, the finite element method is used to obtain ... -
Nonlinear optical properties in AlxGa1-xAs/GaAs double-graded quantum wells: The effect of the structure parameter, static electric, and magnetic field
(Elsevier, 2022)We present a theoretical simulation of the impact of applied external electric and magnetic fields, as well as of the change in structure parameters, on the nonlinear optical rectification (NOR), second harmonic ... -
Novel automatic group identification approaches for group recommendation
(Elsevier, 2021)Group recommender systems are specialized in suggesting preferable products or services to a group of users rather than an individual by aggregating personal preferences of group members. In such expert systems, the initial ... -
Novel natural spider silk embedded electrospun nanofiber mats for wound healing
(Elsevier, 2021)In recent years, electrospun nanofiber mats based on biopolymers have been extensively investigated for tissue and biomedical engineering, mainly because of remarkable morphological similarity with the natural ... -
Optimization of temperature and pretreatments for methane yield of hazelnut shells using the response surface methodology
(Elsevier, 2020)In this study, NaOH pretreatment, H2SO4 pretreatment, thermal pretreatment and production temperature were optimized to ensure maximum methane yield from hazelnut shells (HS) using the response surface methodology (RSM). ... -
Preparation and characterization of nanosized Fe3O4-biochar electrocatalysts with large surface area for H2O2 sensing
(Elsevier, Nisan 2022)A nanoscale Fe3O4-biochar (Fe-BC) composite material was prepared using hazelnut shell (HNS) biochar and FeCl2. Biochar was prepared by phosphoric acid (H3PO4)-assisted pyrolysis (BCA) and H3PO4 + microwave (MW)-assisted ... -
Removal of Cr(VI) from tanning wastewater using chitosan-SDS complexes in PEUF: Optimization and analysis via response surface methodology
(Elsevier, 2023)In this study, we addressed the removal of hexavalent chromium (Cr(VI)), a highly toxic and soluble anionic heavy metal, using enhanced ultrafiltration (UF). The objective was to eliminate Cr(VI) species with molecular weights ... -
Sequential use of the electrocoagulationelectrooxidation processes for domestic wastewater treatment
(Elsevier, 2022)Nowadays, the decrease in useable water resources day by day necessitates studies on the protection of resources by treating wastewater. It is also one of the best options for reusing the water to be treated, and electrochemical ... -
Shallow mixing and column performances of lime, fly ash and gypsum on the stabilization of swelling soils
(Elsevier, 2021)Swelling soils are problematic in terms of geotechnique and they necessitate mitigation actions in preliminary works. The most commonly used method to mitigate the damage caused by swelling soils is to stabilize soil with ... -
Treating adverse effects of blockbuster bias on beyond-accuracy quality of personalized recommendations
(Elsevier, 2022)Collaborative filtering recommendation algorithms are vulnerable against the popularity bias, including the most popular items repeatedly into the produced ranked lists. However, the research on popularity bias focuses ...
