First-principles methods have started to be widely used in materials science for the prediction of propel-ties of metals, alloys, and compounds. In this study, we demonstrate how first-principles methods can be used to predict the average open-circuit voltage that can be obtained from a lithium battery with spinel or layered manganese oxides used as the cathode. For this purpose we combine a basic thermodynamical model with the ab initio pseudopotential method. The good agreement between the computed and experimental average output potentials suggests that first-principles methods can be an important tool to design novel battery materials.

Theoretical prediction of bulk glass forming ability (BGFA) of Ti-Cu based multicomponent alloys
SUER, Sila; Mehrabov, Amdulla; Akdeniz, Mahmut Vedat (Elsevier BV, 2009-03-01)
The bulk glass forming ability (BGFA) of Ti-Cu based multicomponent alloys has been evaluated via theoretical modeling and computer simulation studies based on a combination of electronic theory of alloys in the pseudopotential approximation and the statistical thermodynamical theory of liquid alloys The. magnitude of atomic ordering energies, calculated by means of the electronic theory of alloys in the pseudopotential approximation, was subsequently used for calculation of the key thermodynamic parameters...
Efficient Ceria-Supported Rhodium Nanoparticles as an Electrocatalyst for Hydrogen Evolution
Akbayrak, Merve; Önal, Ahmet Muhtar (The Electrochemical Society, 2019-12-13)
Rh-0/CeO2 catalystwas prepared by the reduction of Rh+3 ions on CeO2 surface and characterized by transmission electron microscopy, inductively coupled plasma optical emission spectrometry, X-ray photoelectron spectroscopy and powder X-ray diffractometry techniques. To investigate its electrocatalytic activity for H-2 evolution reaction, a glassy carbon electrode (GCE) was modified with Rh-0/CeO2. The modified electrode was found to exhibit a high electrocatalytic activity (turnover frequency (TOF): 1.56 s(...
Paper Based Glucose Biosensor Using Graphene Modified with a Conducting Polymer and Gold Nanoparticles
GOKOGLAN, Tugba Ceren; KESİK, Melis; SOYLEMEZ, Saniye; YÜKSEL, Recep; Ünalan, Hüsnü Emrah; Toppare, Levent Kamil (The Electrochemical Society, 2017-01-01)
In this work a novel approach was reported for glucose detection using disposable paper based electrodes consisting graphene modified with a conducting polymer, glucose oxidase (GOx) and gold nanoparticles. For the first time, a conducting polymer; poly(9,9-di-(2-ethylhexyl)-fluorenyl-2,7-diyl)-end capped with 2,5-diphenyl-1,2,4-oxadiazole (PFLO) was spread over graphene coated papers and used as a matrix for glucose detection. To finalize the desired biosensor, the enzyme GOx was immobilized with gold nano...
PARTIAL MOLAR PROPERTIES OF MGCL2 IN MGCL2-KCL-CACL2 MELTS
ZHU, J; Karakaya, İshak; THOMPSON, WT (The Electrochemical Society, 1988-01-01)
To further the understanding of electrolytes of value in industrial magnesium electrolysis, the reversible emf for the formation of in fused salts containing and was studied. The data made possible the calculation of thermodynamic solution properties which were used with other data to construct features of the ternary phase diagram. The multiple discrete complex anion (MDCA) model was tested against the thermodynamic findings from the present study. Reasonable agreement was obtained between the experimen...
Can chemically etched germanium or germanium nanocrystals emit visible photoluminescence?
Kartopu, G; Karavanskii, VA; Serincan, U; Turan, Raşit; Hummel, RE; Ekinci, Y; Gunnaes, A; Finstad, TG (Wiley, 2005-06-01)
Photoluntinescence (PL) properties of various Ge-based nanostructured materials, prepared using methods such as chemical etching, ion implantation and spark processing, have been studied. The PL was much stronger from the samples containing Ge nanocrystals, in comparison with their counterparts with no or less Ge nanoparticles, hinting at the likely role of the quantum confinement in Ge nanocrystals (NCs) in the light emission process. On the other hand, defects in the oxides or Ge-O bonded material alone a...
