Chemical Upcycling of Polyphenylene Sulfide at Room Temperature

open access: yesAdvanced Science, EarlyView.
Poly(phenylene sulfide) (PPS) is a semi‐crystalline super engineering plastic with exceptional properties. An iron‐photocatalyzed strategy is reported for chemical upcycling of PPS plastics at room temperature using 1,2‐dichloroethane. The method demonstrates remarkable efficiency across diverse PPS resins and post‐consumer composites, even within ...

Rapid Determination of Lead in Barium-bearing Ores by EDTA Compleximetry

open access: yesYankuang ceshi, 2013
For the determination of lead content in barium-bearing samples by the EDTA volumetric method, the lead analysis result is low due to the presence of lead sulfate and barium sulfate double salt formed during the analysis process.

Barium aspiration ‐ Accident or complication?

open access: yesClinical Case Reports, 2020
Aspiration of barium sulfate is possible during radiographic contrast procedures and is potentially life‐threatening in severe cases. In patients with dysphagia or suspected tracheoesophageal fistula, barium compounds may be used, considering lateral ...

Cortical Somatostatin Neurons Regulate Seizure Susceptibility via MINAR1/Gαs–cAMP Signaling

open access: yesAdvanced Science, EarlyView.
Our study identifies MINAR1 as a novel regulator of cortical interneuron excitability and seizure susceptibility. MINAR1 is preferentially expressed in SST+ interneurons. Genetic ablation of MINAR1 leads to seizure hypersensitivity, reduced SST+ neuron excitability, and impaired Gαs–cAMP signaling, disrupting the E/I balance.

Stepwise De‐solvation and Diffusion Kinetics of Hydrated Zn‐ion in Hierarchical Porous Carbon Anode for Improved EDLC Behavior

open access: yesAdvanced Science, EarlyView.
The size mismatch between the micropore channel and [Zn(H2O)6]2+ in porous carbon anode during the discharge process was addressed by regulating the hierarchical channel. The inducted stepwise de‐solvation of [Zn(H2O)6]2+ significantly reduced its de‐solvation energy, promoted the EDLC behavior, and strengthened the diffusion kinetic.

An integrated multicriteria decision making framework for the selection of waste cement dust filled automotive brake friction composites

open access: yesScientific Reports
This work discusses selecting optimal brake friction composite alternatives based on an integrated MABAC (multi-attributive border approximation area comparison) and AHP (analytic hierarchy process) approach.
