Background There are few randomized controlled trials (RCTs) in pediatric surgery, and their risk of bias is unknown. There is also little known about the methodological or reporting quality of systematic reviews (with or without meta-analyses) in pediatric surgery. Therefore, we conducted a cross-sectional meta-research study to determine the risk of bias and reporting quality of RCTs and systematic reviews and meta-analyses in pediatric surgery, and the associations between these outcomes and study characteristics. Methods We searched MEDLINE, Embase, Cochrane Library, JBI EBP database, Centre for Reviews and Dissemination and Web of Science for all RCTs and systematic reviews in pediatric surgery published in 2021. We also searched the 2021 indexes of high-impact pediatric surgery journals. We assessed the risk of bias and reporting quality of RCTs using the RoB 2 and CONSORT tools respectively. We assessed the same parameters for systematic reviews and meta-analyses using the ROBIS and Preferred Reporting Items for Systematic Reviews and Meta-analyses tools. Findings We found 82 RCTs and 289 systematic reviews/meta-analyses published in 2021. More than half ( n = 46, 56%) of RCTs and almost all (n = 278, 96%) systematic reviews and meta-analyses were at high risk of bias. Only one (1%) RCT and four (1%) systematic reviews and meta-analyses were adequately reported. Less than half ( n = 40, 49%) of RCTs and just over a quarter ( n = 77, 27%) of systematic reviews and meta-analyses had a registered protocol. Surprisingly, we found that more than half of systematic reviews and meta-analyse ( n = 162, 56.1%), had no risk of bias assessment. Conclusions Recently published RCTs and systematic reviews in pediatric surgery are at high risk of bias and have poor reporting quality. Journals, universities, and research institutions should train authors to conduct and report higher quality studies and develop strategies to reduce risk of bias. However, research with high bi

Lithium sulfide (Li 2 S) is considered as a promising cathode material for sulfur-based batteries. However, its activation remains to be one of the key challenges against its commercialization. The extraction of Li + from bulk Li 2 S has a high activation energy ( E a ) barrier, which is fundamentally responsible for the initial large overpotential. Herein, a systematic investigation of accelerated bulk Li 2 S oxidation reaction kinetics was studied by using organochalcogenide-based redox mediators, in which phenyl ditelluride (PDTe) can significantly reduce the E a of Li 2 S and lower the initial charge potential. Simultaneously, it can alleviate the polysulfides shuttling effect by covalently anchoring the soluble polysulfides and converting them into insoluble lithium phenyl tellusulfides (PhTe-S x Li, x >1). This alters the redox pathway and accelerates the reaction kinetics of Li 2 S cathode. Consequently, the Li||Li 2 S-PDTe cell shows excellent rate capability and enhanced cycling stability. The Si||Li 2 S-PDTe full cell delivers a considerable capacity of 953.5 mAh g −1 at 0.2 C.

Electrolyte Interphases in Aqueous Batteries

The narrow electrochemical stability window of water poses a challenge to the development of aqueous electrolytes. In contrast to non-aqueous electrolytes, the products of water electrolysis do not contribute to the formation of a passivation layer on electrodes. As a result, aqueous electrolytes require the reactions of additional components, such as additives and co-solvents, to facilitate the formation of the desired solid electrolyte interphase (SEI) on the anode and cathode electrolyte interphase (CEI) on the cathode. This review highlights the fundamental principles and recent advancements in generating electrolyte interphases in aqueous batteries.

Triptycene-Fused Sterically Shielded Multi-Resonance TADF Emitter Enables High-Efficiency Deep Blue OLEDs with Reduced Dexter Energy Transfer

引用

Angewandte Chemie 2023年第32期135卷

Designing multi-resonance (MR) emitters that can simultaneously achieve narrowband emission and suppressed intermolecular interactions is challenging for realizing high color purity and stable blue organic light-emitting diodes (OLEDs). Herein, a sterically shielded yet extremely rigid emitter based on a triptycene-fused B,N core (Tp-DABNA) is proposed to address the issue. Tp-DABNA exhibits intense deep blue emissions with a narrow full width at half maximum (FWHM) and a high horizontal transition dipole ratio, superior to the well-known bulky emitter, t -DABNA. The rigid MR skeleton of Tp-DABNA suppresses structural relaxation in the excited state, with reduced contributions from the medium- and high-frequency vibrational modes to spectral broadening. The hyperfluorescence (HF) film composed of a sensitizer and Tp-DABNA shows reduced Dexter energy transfer compared to those of t -DABNA and DABNA-1. Notably, deep blue TADF-OLEDs with the Tp-DABNA emitter display higher external quantum efficiencies (EQE max =24.8 %) and narrower FWHMs (≤26 nm) than t -DABNA-based OLEDs (EQE max =19.8 %). The HF-OLEDs based on the Tp-DABNA emitter further demonstrate improved performance with an EQE max of 28.7 % and mitigated efficiency roll-offs.
