Thermal grooving by surface diffusion: a review of classical thermo-kinetics approach
(Hitit University, 2017)
In polycrystalline materials wherever a grain boundary intersects a free surface and whenever the topographic variation associated with the atomic motion is favored by total free energy dissipation, the material surface ...
Mechanochemical activation of sodium geopolymers containing carbon-nano powder
(Gazi Üniversitesi, 2017)
Mekanokimyasal aktivasyon için 9 veya 18 mol karbon nano-tozlar içeren iki farklı sodyum geopolymer iyi bilinen geopolymer yöntemi ile hazırlanmıştır. 9 mol karbon, geopolimer üretimi aşamasında geopolimer reçineye dahil ...
Geopolimerlerden mekanokimyasal aktivasyon ile silisyum karbür tip nano parçacıkların üretilebilirliğinin araştırılması
(Gazi Üniversitesi, 2017)
Mekanokimyasal olarak 6, 12, 24, 48 saat süreyle aktive edilen ve M= (Na+ veya K+) olmak üzere, sodyum veya potasyum alkali metal içeren (M2OoAl2O3o4.5SiO2o12H2O+18C) geopolimer karbon kompozisyonlarının karbotermal ...
Structural, electronic, and electrochemical analyses of sputter-coated Pt and Pt–Co/GCE electrodes with ultra-low metal loadings for PEM fuel cell applications
(Springer Netherlands, 2017)
In this study, unsupported platinum and platinum–cobalt ultra-thin catalyst layers with varying metal loadings were prepared by a sequential magnetron sputtering technique. The deposited catalyst layers were characterized ...
Fully reacted high strength geopolymer made with diatomite as a fumed silica alternative
(Elsevier Ltd, 2017)
Geopolymers are formed by mixing of aluminosilicate sources with alkaline meta-silicate solution at room temperature. In the current study, diatomite of Turkish origin was fully utilized as a fumed silica alternative for ...
