The nematic-smectic A tricritical phase transition has been studied in binary mixtures of liquid crystals. By making the analogy between the "quasi-binary" fluid mixture and binary mixture of liquid crystals, we adapt the thermodynamic model for fluid mixtures due to Griffiths to the case of mixtures of liquid crystals.

Flexible waveguides with amorphous photonic materials
Sarihan, Murat Can; Yilmaz, Yildirim Batuhan; Erdil, Mertcan; Aras, Mehmet Sirin; Yanik, Cenk; Wong, Chee Wei; Kocaman, Serdar (2019-01-01)
Amorphous photonic materials offer an alternative to photonic crystals as a building block for photonic integrated circuits due to their shared short-range order. By using the inherent disorder of amorphous photonic materials, it is possible to design flexible-shaped waveguides that are free from restrictions of photonic crystals at various symmetry axes. Effects of disorder on photonic crystal waveguide boundaries have examined before, and it is shown that flexible waveguides with high transmission are pos...
Ionic liquid pretreatment allows utilization of high substrate loadings in enzymatic hydrolysis of biomass to produce ethanol from cotton stalks
Haykir, Nazife Isik; Bakir, Ufuk (Elsevier BV, 2013-11-01)
To enhance the enzymatic conversion of cotton stalks to glucose at high substrate loadings and subsequently to produce ethanol, biomass was subjected to ionic liquid and alkaline pretreatments. Ionic liquid, 1-ethyl-3-methylimidazolium acetate (EMIMAc), which reduced biomass crystallinity, was effective in improving the conversion of cotton stalks to glucose (82-85%) regardless of the substrate loading used during enzymatic hydrolysis. On the other hand, the glucose yield decreased from 67% to 55% with an i...
Cloud point preconcentration of germanium and determination by hydride generation atomic absorption spectrometry
Boyukbayram, AE; Volkan, Mürvet (2000-07-14)
Cloud point methodology has been successfully employed for the preconcentration of germanium at trace levels from aqueous samples prior to hydride generation flame atomic absorption spectrometry (HGAAS). Germanium was taken into complex with quercetin in aqueous non-ionic surfactant (Triton X-114) medium and concentrated in the surfactant rich phase by bringing the solution to the cloud point temperature (19 degrees C). The preconcentration of only 50 mi of solution with 0.1% Triton X-114 and 2 x 10(-5) M q...
Linewidth narrowing and purcell enhancement in photonic crystal cavities on an Er-doped silicon nitride platform
Gong, Yiyang; Makarova, Maria; Yerci, Selçuk; Li, Rui; Negro, Luca Dal; Vučković, Jelena (null; 2010-12-01)
Light emission from Er-doped amorphous silicon nitride coupled to photonic crystal resonators is studied. The results demonstrate Purcell enhanced Er absorption and linewidth narrowing of the cavity resonance with increasing pump power.
Linewidth narrowing and Purcell enhancement in photonic crystal cavities on an Er-doped silicon nitride platform
Gong, Yiyang; Makarova, Maria; Yerci, Selcuk; Li, Rui; Stevens, Martin J.; BAEK, Burm; Yerci, Selçuk; Hadfield, Robert H.; Dorenbos, Sander N.; ZWİLLER, Val; Vuckovic, Jelena; Dal Negro, Luca (2010-02-01)
Light emission at 1.54 mu m from an Er-doped amorphous silicon nitride layer coupled to photonic crystal resonators at cryogenic and room temperatures and under varying optical pump powers has been studied. The results demonstrate that small mode volume, high quality factor resonators enhance Er absorption and emission rates at the cavity resonance. Time resolved measurements give 11- to 17-fold Purcell enhancement of spontaneous emission at cryogenic temperatures, and 2.4-fold enhancement at room temperatu...
