Ms. Yun Liu | Material Science | Research Excellence Award 

Ms. Yun Liu | Beihua University | China

Yun Liu is a materials researcher affiliated with Beihua University, specializing in wood protection, wood anatomy, and weather-resistant material modification. With a strong academic foundation supported by a Master’s degree in Materials and Chemical Engineering, Yun Liu has developed expertise in material characterization, performance testing, and advanced analytical techniques used to evaluate structural, chemical, and aesthetic changes in lignocellulosic materials. A key contribution of Yun Liu’s work is the innovative investigation into the dynamic weathering behavior of heat-treated wood. This research integrates continuous monitoring of visual and structural degradation with in-depth chemical analysis, offering a holistic framework for understanding the durability of modified wood materials. By correlating changes in color, gloss, and surface properties with transformations in lignin, extractives, and microstructural features, the study provides essential insights into how heat treatment influences early-stage weathering. Importantly, the findings reveal that heat treatment adjusts the degradation pathways of lignin, contributing to enhanced color stability rather than merely slowing chemical deterioration. This mechanistic understanding supports the development of targeted modification strategies for improving the long-term service life and aesthetic performance of outdoor wood products. Yun Liu has published as first author in the journal Polymers, where the study on dynamic weathering of heat-treated Chinese fir highlights the scientific and practical relevance of this research. This work establishes a foundation for future advancements in sustainable wood protection technologies and environmentally conscious material engineering. Committed to academic integrity and professional growth, Yun Liu maintains active research links through recognized scholarly platforms and contributes to the broader scientific community through collaboration and knowledge dissemination. With a focus on innovation, material durability, and eco-friendly wood modification, Yun Liu aims to advance high-impact research aligned with the standards of the Research Excellence Award category.
