Abstract

The article discusses Lupus Miliaris Disseminatus Faciei (LMDF), a rare inflammatory skin condition primarily affecting the face. Reflectance confocal microscopy (RCM) was used to study the skin lesions of seven patients with LMDF, revealing specific features such as inflammatory cells, granulomas, and dilated vessels in the dermis. The study aimed to describe the RCM features of LMDF and their correlation with pathology, providing valuable insights for diagnosis and treatment. Further research is needed to fully characterize the RCM findings in LMDF. [Extracted from the article]

Abstract

The application of Si-based anodes is mainly impeded by their intrinsic volumetric stress. Recently proposed elastic binders have been demonstrated as an efficient approach to alleviate this large stress, but the excessive dosage of binders leads to inadequate energy density. Herein, a 3D resilient ion/electron dual conductive network (LPCC) composed of carboxylic carbon nanotubes (c-CNTs) interwoven with carboxymethyl chitosan (c-CS) and lithiated poly(acrylic acid) (LiPAA) was developed. The formed covalent and hydrogen bonds can endure and dissipate volumetric stress, thereby maintaining electrode integrity. Additionally, the LPCC network intimately wraps Si–C particles and provides a continuous ion/electron dual conductive skeleton. Therefore, this novel 3D network enables Si–C anodes to deliver superior electrochemical performance even at a high Si–C content of 96 wt%. Moreover, an NCM811‖Si–C/LPCC full-cell (>3.1 mA h cm−2) achieves unprecedented high gravimetric and volumetric energy densities of 510 W h kg−1 and 1173 W h L−1, respectively. This study provides novel insights for developing efficient Si-based binders for next-generation high-energy-density systems. [ABSTRACT FROM AUTHOR]

82. Solvation structure fine-tuning enables high stability sodium metal batteries.

Abstract

Unstable solid electrolyte interface (SEI) films, disordered growth of sodium dendrites and relatively large volume expansion of metal sodium are huge bottlenecks for the safety and stability of sodium metal batteries (SMBs). Herein, 2-propyn-1-ol methanesulfonate (PMS) has been proposed as a preferential anode film-forming additive to stabilize Na‖Na3V2(PO4)3 (NVP) batteries. Molecular dynamics simulations indicate that PMS additive can actively induce the solvation behavior of fluoroethylene carbonate (FEC), effectively suppressing further decomposition of solvent molecules. Moreover, in situ optical experiments, scanning electron microscopy, and X-ray photoelectron spectroscopy indicate that PMS and FEC synergistically construct a SEI film rich in inorganic components such as NaF and Na2S, significantly inhibiting the growth of sodium dendrites. Consequently, Na‖NVP full cells in 3 vol% PMS electrolyte exhibit ultra-high average coulombic efficiency of 99.9% and a capacity retention rate of 92% after 1000 cycles at 2C. This work offers an optimistic prospect for achieving safe and stable SMBs. [ABSTRACT FROM AUTHOR]
