The present study was undertaken to improve photocatalytic efficiency of TiO2 powder by silver doping and/or particle size reduction through mechanical ball milling. A planetary ball mill was employed to reduce the particle size of TiO2 powders to nanoscale and silver loading to TiO2 powders. Silver nitrate was used as silver source to obtain about 1% Ag load. Slurry taken from ball mill was separated by centrifugal separator into nano and micro sols. Separated nanosol was taken into the furnace to be dried...
Production of graded porous polyamide structures and polyamide-epoxy composites via selective laser sintering
Jande, Yusufu A. C.; Erdal Erdoğmuş, Merve; Dağ, Serkan (SAGE Publications, 2014-06-01)
Selective laser sintering was used for producing uniformly porous and graded porous polyamide structures. The porous structures were infiltrated with epoxy to produce composites. The porous and composite specimens were physically and mechanically characterized. Within the capabilities of the selective laser sintering machine and the materials used, porosities in the range 5-29% could be obtained in a controlled, repeatable manner. The ultimate tensile strength of the produced uniformly porous polyamide stru...
Production of martite nanoparticles with high energy planetary ball milling for heterogeneous Fenton-like process

Natural martite microparticles (NMMs) were prepared with a high energy planetary ball mill to form a nanocatalyst for a Fenton-like process. Martite nanoparticles (MNs) of different scales are formed when the milling time ranges from 1 to 5 h at the milling speed of 300 rpm. The catalytic performances of MNs are higher than the NMMs for the degradation of acid blue 5 (AB5) in a heterogeneous Fenton- like process. The NMMs and the MNs were characterized by SEM, EDX, BET, XRD and FT-IR analyses. The size dist...
Production of graphene oxide and polymer based nanocomposite microsieves via breath figure method
Kıratlı, Ayşe Elif; Bat, Erhan; Çulfaz Emecen, Pınar Zeynep; Department of Chemical Engineering (2017)
Porous polymer films are used in various different fields such as electronics, sensors, biomedical, catalysis, and separation. Breath figure (BF) is a method of obtaining porous polymers via a self-assembly process based on water condensation. In this process condensed water droplets can be regularly arranged on surface depending on process conditions. They continue to grow or sink until all solvent is evaporated. After complete evaporation, honeycomb shaped porous polymeric films are obtained. Amphiphilic ...
Production of boron nitride nanotubes from the reaction of NH₃ with boron and iron powder mixture
Noyan, Selin; Sezgi, Naime Aslı; Department of Chemical Engineering (2012)
Boron nitride nanotubes (BNNTs), which are structurally similar to carbon nanotubes (CNTs), were synthesized in 1995 for the first time. They are made up by folding atom sheets which consist of boron and nitrogen atoms into cylindrical form. After their discovery, BNNTs have been attracting great attention due to their extraordinary mechanical, thermal, electrical, and optical properties. In this study, BNNTs were synthesized from the reaction of ammonia gas with the boron and iron powder mixture in a tubul...
