Summary: Lignin-derived carbon electrode materials with a high carbon content and a rich benzene ring structure were studied for supercapacitors, and it was found that the nanoporous structure significantly affects the capacitive performance. Three nitrogen-doped nanoporous carbons were prepared using alkali lignin as a carbon source, and the effect of different nanopore distributions on the electrochemical performance was examined. The carbon activated by ZnC2O4 showed a hierarchical porous structure composed of nanosheets, enabling it to store charge and transfer ions simultaneously. It achieved a maximum specific capacitance of 254F/g at 0.5 A/g, surpassing the microporous-dominated carbon activated by K2CO3 and mesoporous-dominated carbon obtained by the SiO2 template method. This study provides theoretical guidance for the preparation of excellent lignin-derived carbon electrode materials.

Summary: This study used natural language processing to create a cohort of nonalcoholic fatty liver disease (NAFLD) patients in primary care. The study assessed advanced fibrosis risk using the Fibrosis-4 Index (FIB-4) and NAFLD Fibrosis Score (NFS), and evaluated the agreement between these risk scores. The study found that many patients had elevated FIB-4 and NFS risk scores, and these risk categories were often in disagreement. The choice between FIB-4 and NFS for fibrosis risk assessment can impact clinical decision-making and may contribute to disparities of care.

Summary: A novel n-i heterostructure strategy using CeO2 and amorphous alumina has been proposed to develop composite electrolytes for low-temperature solid oxide fuel cells (LT-SOFCs). The CeO2/a-Al2O3 electrolyte exhibits high ionic conductivity and fuel cell performance due to the suppressing effect on electron conduction and the promotion of ion transport caused by the potential energy barrier and thermoelectric effect at the heterointerface. This study presents a practical electrolyte design and opens frontiers in developing high-efficiency electrolytes for LT-SOFCs using insulating materials.

Summary: In this study, we demonstrated the improvement in output power of a self-frequency-doubling (SFD) green laser in Nd:LCB crystal. The spectra were measured and calculated using the Judd-Ofelt theory, providing design guidelines for SFD lasers. By taking advantage of energy level splitting of Nd3+ ions, we achieved an output power of 1.7W for a SFD green laser at a wavelength of 540nm, which represents the highest output power in the Nd:LCB crystal and avoids intrinsic absorption of Nd3+ ions. This work not only develops a promising SFD laser crystal, but also provides an effective approach for enhancing SFD laser output power.
