ZrO2 coating via e-beam evaporation on PE separators for lithium-ion batteries
(Springer Heidelberg, 2021)
In this paper, ZrO2 is deposited on a polyethylene-based separator via electron beam evaporation method. The analyses reveal that the application of the ceramic-based coating enhances the electrolyte uptake capability from ...
Production and characterization of re3+:Yb2o3 nanoparticles
(Trans Tech Publications Ltd, 2021)
In this study, doped ytterbium oxide (Yb2O3) nanoparticles (NPs) with different dopant type (Eu and/or Tb) and undoped were synthesized by wet chemical method using nitrate salt as a starting source. Afterwards, they were ...
Synthesis, characterization and radioluminescence properties of erbium-doped yttria phosphors
(Springer, 2021)
Radioluminescence (RL) behaviour of erbium-doped yttria nanoparticles (Y2O3:Er3+ NPs) which were produced by sol-gel method was reported for future scintillator applications. NPs with dopant rates of 1at%, 5at%, 10at% and ...
Effects of dopant rate and calcination parameters on photoluminescence emission of Y2O3:Eu3+ phosphors: A statistical approach
(Elsevier Sci Ltd, 2019)
In this study, Y2O3:Eu3+ phosphorescent powders with different dopant rates were synthesized by sol-gel method. Statistical experimental design methods were used to investigate the effects of calcination temperature (800, ...
Effect of Particle Morphology on Physical, Mechanical and Wear Properties of Cobalt Metal Powders
(Springer India, 2021)
Cobalt is used in applications that require high densities and good mechanical properties. Cobalt powder is used in batteries, cemented carbides, stainless steel, machine tools and also in manufacturing of metal matrix ...
Fabrication and characterization of Yb-doped Y2O3 powders and thin films
(Carl Hanser Verlag, 2020)
Yttrium oxide (Y2O3) and ytterbium (Yb)-doped Y2O3 particles were synthesized via the sol-gel method from the aqueous solution of their nitrate salts. The synthesized powders were then deposited on Corning glass substrates ...
A Novel Permutation Based Solution Representation Technique for Vehicle Routing Problems on GPUs
(2021)
In this study, the vehicle routing problem (VRP) which is a well-known NP-hard combinatorial optimization problem is handled on graphic processing units (GPUs). Solving any kind of VRP is extremely hard when the instance ...
Photoluminescence Investigation of Tb Doped Yb2O3 Phosphors Produced by Precipitation Method
(2021)
In this study, un-doped and Tb doped ytterbium oxide (Yb2O3:Tb3+) particles with different dopant rates (2, 4, 6 and 8 at. %) were produced by precipitation method, followed by subsequent calcination at 1000 °C for 2 h. ...
Farklı kaynaklardan doğal renk maddesi üreten mikroorganizmaların izolasyonu, tanısı ve elde edilen pigmentlerin karakterizasyonu
(Gıda Teknolojisi Derneği, 2013)
Bu çalışmada çeşitli kaynaklardan renk maddesi üreten mikroorganizmalar izole edilmiş ve uygun çözücüler kullanılarak renk maddeleri ortamdan ayrılmıştır. Çözünen renk maddeleri saflaştırılmış ve elde edilen renk maddelerine ...
Fourier dönüşümlü kızılötesi (FTIR) spektroskopisi ve gıda analizlerinde kullanımı
(Gıda Teknolojisi Derneği, 2014)
Kızılötesi (IR) absorbsiyon spektroskopisi bir tür titreşim spektroskopisidir; IR ışınları molekülün titreşim hareketleri tarafından soğurulmaktadır. Her dalga boyunu ayrı ayrı tarama gerekmeksizin hızlı ve yüksek çözünürlükte ...
