Representative work:

Researchers led by Benlin Hu at the Ningbo Institute of Materials Technology and Engineering (NIMTE), Chinese Academy of Sciences, have developed an intrinsically elastic ferroelectric material by integrating ferroelectric response and elastic resilience into a single polymer system through precise slight cross-linking. The team utilized the Soft X-ray Absorption Spectroscopy (sXAS) at the photoemission end-station to investigate the material, confirming its lightly cross-linked internal structure. This research provides new insights for the development of wearable electronics. The findings were published in the prestigious journal Science under the title: Intrinsically elastic polymer ferroelectric by precise slight cross-linking.

A research team led by Professor Junwang Tang at Tsinghua University has proposed the concept of an “intramolecular junction”. They developed a photocatalyst featuring this junction, CTF-1, composed of alternating benzene and triazine units. This intramolecular junction photocatalyst drives the coupling and oxidation of methane to ethanol with high selectivity and significantly enhanced conversion efficiency. Utilizing the operando irradiation soft X-ray absorption spectroscopy (sXAS) capabilities at the photoemission end-station (BL10B) of the Hefei Light Source (HLS), the team investigated the mechanism by which the intramolecular junction regulates charge carriers. This “intramolecular heterojunction” strategy holds promise for the development of highly efficient and selective catalysts for the production of C2+ products via methane C-C coupling. Furthermore, the approach has the potential to be extended to other catalytic reactions. The findings were published in the prestigious journal Nature under the title: “Methane oxidation to ethanol by a molecular junction photocatalyst”.
