      The conventional robotics, which involves utilization of robots made out of hard materials like metals and hard plastics, has helped humankind automate many different sorts of labor and such robots have been assisting the ...
    • Joint design and fabrication for multi-material soft/hybrid robots 

      Aygül, Cern; Kwiczak-Yiğitbaşı, Joanna; Baytekin, Bilge; Özcan, Onur (IEEE, 2019-04)
      The premises of safer interactions with surroundings and the higher adaptability to its environment make soft robotics a very interesting research field. Some robots try to achieve these feats using soft materials in their ...
    • Mechanical control of periodic precipitation in stretchable gels to retrieve information on slastic deformation and for the complex patterning of matter 

      Morsali, Mohammad; Khan, Muhammad Turab Ali; Ashirov, Rahym; Holló, G.; Baytekin, H. Tarık; Lagzi, I.; Baytekin, Bilge (Wiley-VCH Verlag, 2020-03)
      Material design using nonequilibrium systems provides straightforward access to complexity levels that are possible through dynamic processes. Pattern formation through nonequilibrium processes and reaction–diffusion can ...
    • Mechanochemical generation of singlet oxygen 

      Türksoy, Abdurrahman; Yıldız, Deniz; Aydonat, Simay; Bedük, Tutku; Canyurt, Merve; Baytekin, Bilge; Akkaya, E. U. (Royal Society of Chemistry, 2020)
      Controlled generation of singlet oxygen is very important due to its involvement in scheduled cellular maintenance processes and therapeutic potential. As a consequence, precise manipulation of singlet oxygen release rates ...
    • Minimizing friction, wear, and energy losses by eliminating contact charging 

      Sayfidinov, K.; Cezan, S. D.; Baytekin, Bilge; Baytekin, H. T. (American Association for the Advancement of Science, 2018)
      One-fourth of the global energy losses result from friction and wear. Although friction and tribocharging were presented to be mutually related, reduction of friction and wear by eliminating tribocharges on common polymers, ...
    • The morphological changes upon cryomilling of cellulose and concurrent generation of mechanoradicals 

      Laçin, Özge; Kwiczak-Yiğitbaşı, Joanna; Erkan, Meltem; Cevher, Ş. C.; Baytekin, Bilge (Elsevier, 2019)
      With mechanical input, chemical bonds in polymers can be broken. Recently, it was shown that reactive ends formed by homolytic cleavage, so-called mechanoradicals, can be used in driving further chemical reactions or in ...
    • Self-regulating plant robots: bioinspired heliotropism and nyctinasty 

      Cezan, Süleyman Doruk; Baytekin, Hasan Tarık; Baytekin, Bilge (Mary Ann Liebert, 2020)
      Self-regulation (or so-called homeostasis) is a property of all living organisms to maintain an internal stable state through specialized biofeedback mechanisms under varying external and internal conditions. Although these ...
    • Slit tubes for semisoft pneumatic actuators
