The aim of this thesis study was to investigate the effects of composition and sintering variables on the microstructural characteristics of W-rich W-Ni-Co heavy alloys. W-Ni-Co alloys containing 90 to 97 wt% W and different Ni/Co ratios were investigated in the study. The alloys studied were produced by applying conventional powder metallurgy methods and subjected to microstructural and mechanical characterization by using suitable techniques. All of the alloys investigated reached almost full density when...

Liquid crystal (LC) based devices such as displays, spatial light modulators (SLM) and different switchable phase masks constitute the main part of the graphic information display and light control. Mechanical rubbing and photo-alignment are the most widely used industrial technologies to create anisotropic surfaces for these devices. Recently, nonlinear laser lithography (NLL) was introduced as a fast, cost effective method for large area nano-grating fabrication based on laser-induced periodic surface str...
Liquid Crystal-Templated Synthesis of Anisotropic Ultrafiltration Membranes
Karausta, Aslı; Büküşoğlu, Emre (2018-08-30)
In this study, we developed a method that provides determination ofthe internal structure of the polymeric films by using LCs as template. For thesynthesis of the material, we photopolymerized the mixture of reactive(4-(3-acryloyoxypropyloxy) benzoic acid 2-methyl-1,4-phenylene ester (RM257))and non-reactive (4-cyano-4′-pentylbiphenyl (5CB)) mesogens confined in filmgeometries with thickness of 20-200 µm, and then extracted nonreactive mesogenswith solvent to yield polymeric films of area in the order of 10...
Liquid Crystal Templates Combined with Photolithography Enable Synthesis of Chiral Twisted Polymeric Microparticles
AKDENİZ, BURAK; Büküşoğlu, Emre (Wiley, 2019-08-01)
Liquid crystals (LC), when combined with photolithography, enable synthesis of microparticles with 2D and 3D shapes and internal complexities. Films of nematic LCs are prepared using mixtures of reactive (RM257) and non-reactive mesogens with controlled alignment of LCs at the confining surfaces, photo-polymerized the RM257 using a photomask, and then extracted the unreacted mesogens to yield the polymeric microparticles. The extraction results in a controlled anisotropic shrinkage amount dependent on the R...
