Overview

Bernard Lotz is affiliated with the University of Strasbourg in France and has contributed extensively to the field of Materials Science, particularly focusing on polymers and plastics. Their research spans various subfields, including biomaterials, mechanical engineering, organic chemistry, and molecular biology.

Their scholarly output is concentrated on topics such as biodegradable polymer synthesis and properties, polymer crystallization and properties, polymer nanocomposites and properties, fiber-reinforced polymer composites, advanced polymer synthesis and characterization, synthesis and properties of aromatic compounds, and supramolecular self-assembly in materials.

Lotz's work has been published in several scientific venues, with a notable presence in the journal Macromolecules, contributing five papers there. Other venues include ChemBioChem, Advanced Fiber Materials, and Polymer Engineering and Science.

Recent publications illustrate a focus on polymer crystal structures and transitions. Key papers include:

  • Original Crystal Structures of Even-Even Polyamides Made of Pleated and Rippled Sheets, 2021, Macromolecules
  • Brill Transition in Nylons: The Structural Scenario, 2021, Macromolecules
  • Fold Surfaces of Polymer Crystals Are Nucleation Sites: The Link between Polymer Decoration, Secondary Crystallization, and the Rigid Amorphous Fraction (RAF), 2023, Macromolecules
  • Rippled Sheets: The Early Polyglycine Days and Recent Developments in Nylons, 2022, ChemBioChem
  • A Fresh Look at the Structures of Nylons and the Brill Transition, 2021, Advanced Fiber Materials

The researcher has collaborated with several coauthors, including Tao Wen, Hao-Jan Sun, Stephen Z. D. Cheng, Ziwei Lai, and Nan Zheng, indicating a networked approach across related fields of polymer science.

Bernard Lotz was recognized as a Fellow of the American Physical Society (APS) in 1985, based on contributions to the understanding of crystalline polymers and polypeptides' crystallography.
