Solid-state metallic potassium batteries (SSMPBs) afresh have attracted incremental attention because of their potential to supplement solid-state metallic lithium batteries. However, SSMPBs suffer poor electrochemical performances due to the low ionic conductivity of solid electrolytes and huge electrode/electrolyte interfacial resistance. Herein, high-rate SSMPBs are achieved by in situ ring-opening polymerization of 1,3-dioxolane with succinonitrile as a plasticizer and Al(OTf) as the catalyst, where the succinonitrile enables short-chain polyether electrolytes.

The Mass Spectrometry Data Center (MSDC) has recently started improving existing libraries and creating new ones for identifying and analyzing plastics-related compounds (PRC) and materials (PRM) as part of the NIST circular economy program. PRC are small molecules of dissimilar chemical nature; hence, to increase coverage, we have used three types of ionizations: EI, ESI, and APCI. PRM are solids that include polymers, polymer mixtures, and commercial plastics, so we have used pyrolysis-gas chromatography (py-GC-MS) to create a new searchable library.

Burn wounds are challenging to treat due to considerable tissue damage and fluid loss. Creating wound dressings from natural and biological materials makes it possible to treat wounds and promote rapid epithelialization to speed healing and restore skin function. As a result, the ability of a collagen scaffold (Col) made from rainbow trout (Oncorhynchus mykiss) and putative bioactive phytochemical components from a Sargassum glaucescens (S.

January 2025
Department of Restorative Dentistry, Graduate School of Dental Medicine, Hokkaido University, Sapporo, Japan.
Objectives: To evaluate the shear bond strength (SBS) of universal cements (UCs) to dentin prepared with different diamond burs using various adhesive strategies.
Materials And Methods: One-hundred-twenty molars were prepared to expose the mid-coronal dentin. The teeth were divided into two groups according to diamond bur preparations: coarse and super-fine grit burs.
Do perilunate dislocations and fracture-dislocations result in different radiological outcomes following wrist alignment reconstruction? A single-center retrospective study including 51 patients with perilunate injuries.

Introduction: Perilunate dislocations (PLD) and perilunate fracture-dislocations (PLFD) are high-energy wrist injuries often linked to significant post-traumatic osteoarthritis. This study aims to determine whether PLD and PLFD yield different radiological outcomes following surgical treatment while identifying prognostic factors for worse outcomes.
Materials And Methods: We retrospectively analyzed 51 patients treated for perilunate injuries between 2000 and 2022.
