    Feedback and Reactive Flow Effects on Living Crystal Formation
    (Elsevier, 2022) Zafer, Ayturk Hamdi; Akguc, Gursoy B.
    Active spherical particles in a water film form aggregate on two neighboring water bubbles, where one of the bubbles' half surface is heated by a laser source, creating a convective flow field. The specific geometry is similar to the experimental setup we used for colloidal particles (Ilday et al., 2017). Water flow is considered reactive during the simulation due to changing flow field, as well as temperature field. A feedback interaction is introduced, which may be due to the concentration of particles in some region of fluid, effectively a time-dependent accumulation. We show the effect of attractive and repulsive feedback forces, and observe, under attractive feedback, the formation of patches of aggregate distributed all over the space, and eventually a greater aggregate formation on the bubble surface. Reactive flow effects, with and without feedback effects, are analyzed, by examining the pair correlation and mean square displacement indicators, as well as the single-particle trajectories.

    Active Particle Aggregate on Complex Bubble Surfaces
    (Canadian Science Publishing, Nrc Research Press, 2018) Akguc, Gursoy B.
    Recently, colloids have been shown to form complex structures on bubble surfaces on demand. With the help of a high power pulse laser shining on a thin water film, water bubbles can be formed and heat unbalance creates a convective flow, which carries colloids on the surface of these water bubbles to form aggregates. Here, active particles are studied in a similar setup and conditions are laid out to form aggregates on water bubble surfaces. The effect of motility and chirality of active particles on formation of aggregate are discussed. The simulation results obtained here will hopefully help the experimental endeavors in future.

    Stirring Active Particles To Form Life Crystal Using Convective Flow
    (Elsevier, 2019) Akguc, Gursoy B.
    A convective flow concentrating active particles in a region bounded by complex surfaces can be used as a dynamic confinement to form aggregates. To achieve this, a special geometry inspired by thin film experiments was modeled. There is a discussion of the effect of motility and chirality of active particles in the formation of crystalline like structures. (C) 2018 Elsevier B.V. All rights reserved.

    Thermoelectric Efficiency of Nanowires in Contact.
    (Amer Inst Physics, 2018) Akguc, Gursoy B.
    Divergence of density of state near Fermi level at low dimensional systems helps to increase efficiency of thermoelectric materials. It is shown here two contacting nanowires in the middle results in electron conduction resonances that enhance the efficiency of overall thermoelectric output of the system. A non-linear response approach as well as efficiency at max power are necessary ingredients for the analysis.

    Aktif Nano Parçacıkların İki Boyutlu Karmaşık Yüzeylerde İncelenmesi; Yaşayan Kristal Oluşumu
    (2021) Zafer, Aytürk Hamdi; Akgüç, Gürsoy Bozkurt
    İnce su filmindeki aktif küresel parçacıklar birisi lazer kaynağı ile ısıtılmış komşu iki su kabarcığı üzerinde ısıdan dolayı oluşan su akıntısı yardımıyla birikirler. Bu özel geometri daha önce pasif parçacıklar için yapılan deneyimizden alınmıştır. Su akışı zamanla değişen birikinti dolayısı ile farklılık gösterir bu anlamda aktif bir akım olarak düşünülebilir. Ayrıca parçacıkların arasında bir zaman bağımlı geri besleme kuvveti de eklenmiştir. Geri beslemenin çekici veya itici olması incelenmiş çekici bir geri besleme ile öbekleşmeler gözlenmiş birikintinin daha kolay olduğu gözlemlenmiştir. Hem aktif su akımı hem de geri besleme parçacıkların çift korelasyonları ve ortalama uzaklaşma bilgilerine bakılarak tartışılmıştır.
