Thermomechanical Transformations for Thermoelasticity and Superelasticity in Shape Memory Alloys

 We are delighted to announce that Dr. Osman Adiguzel from Firat University, Turkey, will be delivering an insightful presentation at the International Congress on Materials Science and Nanotechnology, scheduled to take place on November 20-22, 2025, at Village Hotel Changi, Singapore, with both in-person and online participation options.

About the Presentation

Shape memory alloys (SMAs) are among the most fascinating classes of smart materials, capable of responding to external stimuli by altering their shapes in a reversible manner. Dr. Adiguzel’s talk, titled “Thermomechanical Transformations for Thermoelasticity and Superelasticity in Shape Memory Alloys”, will focus on the fundamental mechanisms governing these unique behaviors.

The presentation will highlight how SMAs exhibit shape memory effect through thermal and stress-induced martensitic transformations. At low temperatures, deformation leads to stored strain energy, which is later released upon heating, enabling the material to recover its original shape. This process, often described as thermal memory or thermoelasticity, is complemented by superelasticity, where alloys revert to their original form under constant temperature after mechanical stressing.

Dr. Adiguzel will also share findings from x-ray and electron diffraction studies conducted on copper-based alloys such as CuAlMn and CuZnAl. These investigations reveal complex layered structures and superlattice reflections, offering deeper insights into atomic rearrangements, lattice twinning, and martensitic transformations that define the remarkable properties of SMAs.

About the Speaker

Dr. Osman Adiguzel is an esteemed physicist with a career spanning over 45 years in academia and research. He graduated from Ankara University in 1974, earned his PhD from Dicle University, and pursued post-doctoral studies at Surrey University, UK. He has published over 80 research papers, supervised several PhD and MSc theses, and contributed extensively as a keynote and invited speaker at more than 120 international and national conferences. Even after his retirement in 2019, he continues to actively engage with the global scientific community, especially through numerous online conferences during the pandemic years.

📢 Keynote Speaker Spotlight: Prof. Vladimir G. Chigrinov on Azodye Nanolayers – New Trend in Liquid Crystal Devices

We are excited to announce that Professor Vladimir G. Chigrinov, from the Hong Kong University of Science and Technology, will be delivering a Keynote Virtual Presentation at the International Congress on Materials Science and Nanotechnology, taking place November 20-22, 2025, in Singapore and Online.

Keynote Title:
Azodye nanolayers: New trend in liquid crystal devices


Abstract

Photoalignment and photopatterning have been explored for decades as promising methods for controlling the molecular arrangement in liquid crystal (LC) devices. Light not only provides the energy required for these processes but also delivers critical phase and polarization information to the material systems.

Recent advancements have shown that photoalignment of liquid crystals using azodye nanolayers enables exceptionally precise molecular alignment within LC cells. Over the years, this technology has undergone numerous refinements, unlocking innovative applications in photonics. Today, it plays a vital role in optical signal processing, communications, and the development of LC-based sensors for detecting external electric fields, pressure, and even air and water flow—making them valuable tools for climate change monitoring.

In his presentation, Prof. Chigrinov will introduce a physical model of photoalignment and photopatterning grounded in rotational diffusion in solid azodye nanolayers. He will further showcase emerging applications in display and photonics, including:

  • High-speed, high-resolution LC displays (e.g., field sequential color ferroelectric LCDs)
  • LC sensors and LC lenses
  • Electrically and optically rewritable LC E-paper
  • Photo-induced semiconductor quantum rods alignment for next-gen displays
  • 100% polarizers based on photoalignment
  • LC smart windows with photopatterned diffraction structures
  • LC antennas with voltage-controlled frequency

About the Speaker

Professor Vladimir G. Chigrinov has been with the Hong Kong University of Science and Technology since 1999 and is globally recognized as a pioneer in flat panel technology. A SID Fellow since 2008, Prof. Chigrinov has authored 6 books, 31 reviews/book chapters, 317 journal papers, 668+ conference presentations, and holds 121 patents (including 36 US patents) in liquid crystal science and technology.

His distinguished career includes numerous awards, such as the Excellent Research Award from HKUST (2012), Gold Medal and Best Award at MTE 2014, the Slotto Owaki Prize of SID (2018), and recognition as a Distinguished Fellow of multiple international scientific institutes. Since 2018, he has also served as Professor at the School of Physics and Optoelectronics Engineering, Foshan University, China.
