NSRRC-associated research images selected for cover of three prestigious journals

Recently the NSRRC has had more international visibility after being on the cover of three prestigious journals. Three NSRRC-associated research were published in the Royal Society of Chemistry: Journal of Materials Chemistry A, Journal of Materials Chemistry C and the Physical Chemistry Chemical Physics. Being the representative image of a journal issue is definitely a source of pride to researchers.

The illustration on the front cover of the Journal of Materials Chemistry C (vol. 6, no. 38, published on 2018/10/14) was chosen from the study led by Prof. Ru-Shi Liu (Department of Chemistry, National Taiwan University). It depicts the synthesis of a nitride phosphor phase, under high pressure. This study adopted powder X-ray synthesis diffraction technique on TLS 01C2, focusing on how different synthesis pressure affects SrLiAl3N4:Eu2+ (SLA) narrow-band red phosphors. The result not only suggests a mechanism of a pressure-induced high-quality phosphor via enhancement of particle size and suppression of defect formation, but also indicates SLA phosphor could be a potential candidate for backlighting.

The image appearing inside the back cover of the Journal of Materials Chemistry A (vol. 6, no. 42, published on 2018/11/14) comes from the collaborative work of Profs. Ming-Jay Deng and Li-Hsien Yeh (Department of Chemical Engineering, National Yunlin University of Science and Technology), and Dr. Jin-Ming Chen (NSRRC). The team successfully fabricated a 3D network of vanadium oxide (VOx) and manganese oxide (MnOx) nanofibers on conductive paper to act as electrodes that were surrounded by an eco-friendly solvent-based gel electrolyte. Such materials have great potential as high voltage wearable asymmetric super capacitors (HVWASCs) suitable for wearable electronic devices and multiple other devices within the Internet of Things (IoT). To analyze the crystal structure and the composition of the electrodes, the team used the NSRRC facilities, X-ray diffraction at SPring-8 12B1 and the X-ray photoemission spectroscopy at TLS 20A, respectively.

The latest issue of Physical Chemistry Chemical Physics (vol. 20, no. 42, published on 2018/11/14) highlights the research from Dr. Chun-Jen Su and Prof. U-Ser Jeng (NSRRC) inside the back cover. The image illustrates structure and binding thermodynamics of melittin-bound, phosphocholine-based unilamellar vesicles (ULVs). This study has potential applications in biomedicine. The investigation demonstrates that the binding affinity of a model peptide melittin to zwitterionic phospholipid ULVs can be enhanced significantly at elevated temperatures owing to thermally enhanced membrane thinning. The data was collected and analyzed at TLS 23A, integrating small-angle X-ray scattering and diffraction and low-angle X-ray diffraction.
