Engineering Piezoelectric Properties: A Glycine Crystal Modification Strategy for Poly(3-hydroxybutyrate) in Tissue Engineering
Dear colleagues! We are pleased to announce the publication of our new paper in the journal Advanced Composites and Hybrid Materials (Impact Factor 21). 🏆
Our research team has successfully addressed a key challenge in the field of biocompatible materials—the weak piezoelectric response of the biodegradable polymer poly(3-hydroxybutyrate) (PHB).
The study developed an innovative composite material based on PHB fibers modified with β-glycine crystals. This approach enabled a significant, more than tenfold increase in the piezoelectric response of the scaffolds without compromising their biocompatibility. 👩‍🔬
Key Achievements:

1. Substantial Enhancement of the Piezoelectric Effect: The lateral piezoelectric response was increased from 0.28 ± 0.13 pm/V to 3.9 ± 1.0 pm/V for the composite with 30% glycine content.
2. Improved Physicochemical Properties: The integration of glycine led to the formation of a nanoporous fiber surface, increased wettability, and a higher degree of polymer crystallinity.
3. Elucidation of the Modification Mechanism: Computational studies revealed the nature of the interaction between glycine molecules and PHB, which involves the formation of hydrogen bonds.

This work opens new prospects for the development of highly efficient materials for regenerative medicine and expands fundamental knowledge in the field of polymer property engineering. 🧪

We congratulate Lada Shlapakova and Anastasia Fetisova, as well as their supervisors from the Research Center "Physical Materials Science and Composite Materials," on their brilliant results! 👏👏👏
Success on prestigious international platforms is a clear testament not only to personal talent and perseverance but also to the effective system of research training at Tomsk Polytechnic University.

Research Engineer and postgraduate student Lada Shlapakova won the diploma for the best oral presentation at the VII International Scientific Conference "Advances in Synthesis and Complexing" in Moscow.
The event, held at RUDN University, brought together leading scientists, researchers, and students from different countries working in the field of chemical synthesis and complexation.

"Participating in the conference provided me with invaluable experience and a powerful impetus for further growth! Such events offer opportunities to present my work to an international audience, establish contacts with colleagues from different countries, exchange ideas, and develop public speaking skills and confidence," shared Lada. "I thank the organizers, the scientific committee, my colleagues, and everyone who supported me in preparing the presentation."

Another victory was achieved by postgraduate student Anastasia Fetisova. She received a diploma for the best oral presentation at the VI International Baltic Conference on Magnetism, held at Immanuel Kant Baltic Federal University (BFU).
The conference served as a platform for interdisciplinary exchange of ideas and discussion of new achievements at the intersection of physics, materials science, and bioengineering.
The scientific program covered key areas of modern science: fundamental and applied magnetism, magneto-optical effects and devices, 2D materials, digital twins in magnetism, as well as additive technologies and "smart" functional composites for biomedical and sensor systems.

Anastasia presented an oral presentation on "Shape memory effect in 3D-printed biocompatible composite poly(lactic acid)-based scaffolds for bone tissue engineering," which sparked keen interest among the participants. The discussion focused on the specifics of printing shape memory effect composites, their biocompatibility, and prospects for use in modern medicine.

We are proud of our young scientists and wish them further discoveries and victories!

The International Conference "Biomaterials: From Research to Practice" (BioMATs 2025) was held from September 22nd to 25th in Moscow at the Institute of Metallurgy and Materials Science. This authoritative forum serves as a platform for presenting cutting-edge research and applied developments in the field of biomaterials for regenerative medicine, implantology, drug delivery, and diagnostics. 🧪🧫🧬
The scientific program focused on key areas: the creation of new biocompatible materials (polymers, ceramics, metals, and composites); engineering methods for surface modification to enhance cell adhesion and biointegration; the development of systems for targeted drug delivery and controlled release; the creation of biosensors and diagnostic platforms based on new materials; as well as issues of standardization and safety assessment of biomaterials.
The event brought together leading Russian and international scientists, engineers, physicians, and industry representatives for an open dialogue, strengthening scientific ties, and promoting innovations in materials science aimed at advancing healthcare and improving the quality of life.
The Center successfully presented its latest developments through oral reports by Director Roman Anatolyevich Surmenev and Research Engineer Lada Evgenyevna Shlapakova. The study "Magneto-Responsive Piezopolymer Matrices for Bone Regeneration" was recognized by the organizers with a commemorative diploma. 🏆
We sincerely congratulate our colleagues on this well-deserved achievement! 🌟
