Porphyrinic N channels of zinc ions for the electrochemical reversibility of zinc plating/stripping.

A Zn-coordinated porphyrinic artificial solid-electrolyte interphase (αSEI) layer, named [Zn]PP-4COO-(Zn), was developed to improve the reversibility of zinc metal plating/stripping in aqueous zinc-ion batteries (ZIBs). Inspired by nitrogen-terminating sites of biological molecules coordinating and transporting zinc in zinc metabolic processes, the αSEI layer was designed with zinc ions connecting porphyrinic building blocks to form two-dimensional clathrate sheets and stacking -plane sheets along the -axis to allow N cages to align and form porphyrinic N channels for zinc transport. The [Zn]PP-4COO-(Zn) αSEI layer was Zn-conductive and structurally durable during repeated stripping/plating.

Multimodality Imaging Features of Various Splenic Lesions: Clinical and Histopathologic Correlation.

The spleen is occasionally referred to as the 'forgotten organ' because splenic lesions are less common and encountered rarely compared to pathologies of other abdominal solid organs. Therefore, although well-demonstrated using various abdominal imaging modalities, radiologists tend to be less familiar with splenic diseases, making interpretation challenging. This study aimed to review common and uncommon splenic diseases and illustrate the multimodal imaging (including ultrasonography, CT, MRI, and PET/CT) features of these lesions in correlation with their histopathology.

Standardized Ultrasound Evaluation for Active Surveillance of Low-Risk Thyroid Microcarcinoma in Adults: 2024 Korean Society of Thyroid Radiology Consensus Statement.

Active surveillance (AS) has been widely adopted as an alternative to immediate surgery owing to the indolent nature and favorable outcomes of papillary thyroid microcarcinoma (PTMC). AS is generally recommended for tumors measuring ≤1 cm without aggressive cytological subtypes, risk of gross extrathyroidal extension (ETE), lymph node metastasis (LNM), or distant metastasis. AS requires careful patient selection based on various patient and tumor characteristics, and ultrasound (US) findings.

Boosting Photocatalytic Selective Oxidation of 5-Hydroxymethylfurfural to 2,5-Diformylfuran via Atomically Bridged Indium in In-SnS.

The photocatalytic conversion of biomass-based platform molecules, such as 5-hydroxymethylfurfural (HMF), holds significant importance for the utilization of biomass resources. This study focuses on the unique ability of atomically bridged indium (In) atoms that encourages inactive SnS surface and steer the selective HMF oxidation process under solar light. Experimental results suggest that In confined SnS structure provides not only favorable sites and electronic structures for the synergistic activation of HMF/O but also benefit in charge carrier dynamics, thus influencing the overall activity and selectivity of the SnS catalyst.
