ÖMER İLDAY MSN Graduate Program and UNAM Self-organization is the spontaneous emergence of an ordered state. Despite its ubiquity, how self-organization reduces entropy was never clarified. In this talk, we present a new theoretical framework, whereby we decompose a self-organized system into two parts, one that gets ordered and another that reduces the entropy of […]
T. SERKAN KASIRGA MSN Graduate Program and UNAM Strong electronic correlations among various degrees of freedoms in solids result in the emergence of fascinating phenomena. To name a few we can list metal-insulator transitions, charge density wave transitions and superconductivity. However, these phenomena are notoriously difficult to study experimentally as they are typically associated with […]
Wonmi Ahn MSN Graduate Program and UNAM Noble metal nanoparticles supporting collective oscillations of conduction electrons, i.e., surface plasmon resonances, exhibit excellent light-focusing ability and high spectral sensitivity to changes in the surrounding medium. These capabilities explain the increasing role of plasmonic nanomaterials in nanoimaging, sensing, energy, and biomedical applications. However, high dissipative losses in […]
Bilge Baytekin MSN Graduate Program and UNAM The mechanism of static electricity generation and mitigation on insulator surfaces upon rubbing/contact is one of the few scientific questions that have remained unanswered for millennia. Static charging (tribocharging) of insulators is not just a scientific mystery – it is also a significant problem, especially critical for various […]
Ayça Arslan Ergül MSN Graduate Program and UNAM In this talk I will not focus on one research, but instead I will try to give glimpses of all the topics that we work on or ideas that we nourish. In this way you may also join or contribute to one of the projects, if you […]
Aykut Erbaş MSN Graduate Program and UNAM There are over 40 million cells in our body. Despite carrying an identical genome, these cells are specialized into 200 different types to undertake particular biological tasks in various tissues. The main factor determining a cell’s biological identity is the type and amount of cell-specific proteins. In turn, […]
Hasan Yılmaz MSN Graduate Program and UNAM Optical waves scattered or emitted by materials carry information in temporal (spectral) or spatial domains. Perhaps, the most prominent example of optical information is an optical image that is created by an optical microscope. With the emergence of information technology, optical information can be digitized and computationally processed. […]
Hasan Yılmaz MSN Graduate Program and UNAM Optical fibers are versatile waveguides that have numerous application areas such as telecommunication, lasers, biomedical and infrared (IR) optics. Hollow-core optical fibers (HCFs) are microstructured fibers with a hollow-core surrounded by cladding elements that further diversify the applications of fibers in nonlinear optics, chemical sensing, plasma generation and […]
Prof. Martin Wegener Karlsruhe Institute of Technology Two-photon based 3D laser printing routinely allows for the making of complex three-dimensional sub-micrometer and nanometer structures and has become a mature, widespread, and commercially available technology. After briefly reviewing the basic principle and the state-of-the-art, I focus on recent progress in my group. This includes replacing two-photon […]
Seymur Jahangirov MSN Graduate Program and UNAM Imagine a system that consists of interconnected cells each having an inner state. The inner state of each cell is changed based on the inner states of a specific subset of cells according to a certain rule. This is a general definition of cellular automata. Now replace those […]
NanoDay will take place on Thursday, May 12th this year as a hybrid event. This annual event held at Bilkent UNAM hosts the best international names in their respective fields and awards the best nano-scale visual through its NanoArt competition. This year on NanoDay, we will be hosting two important names—Prof. Oliver Hayden from […]
Anton Samusev ITMO University Planar periodic structures such as metasurfaces and photonic crystal slabs strongly coupled to an exciton resonance attract particular attention since they provide vast opportunities for on-demand engineering of the dispersion of guided and leaky polariton resonances. In this regard, experimental characterization and control of the over modes’ dispersion is of great […]
