Insights on Prussian Blue Analogue Cathode Material Engineered with Polypyrrole Surface Protection Layer for Aqueous Rechargeable Zinc Metal Battery.

One of the key intricacies against using Prussian blue analogues (PBAs) in aqueous batteries is their gradual dissolution in aqueous electrolytes, resulting in inadequate cycling stability. Besides, the rate capability of PBAs is limited due to their poor electrical conductivity. To overcome these challenges, it is essential to tune the physical and chemical properties of PBAs at the nano regime without affecting the inherent charge storage properties, especially at high-voltage operating conditions.

An Overview of Randomized Controlled Trials Examining Prescription and Nonprescription Pharmacological Interventions for Moderate to Severe Traumatic Brain Injury.

To characterize randomized controlled trials (RCTs) of pharmacological interventions (prescription medications, nonprescription medications, and supplements) for the management of moderate to severe traumatic brain injury (MSTBI). Systematic searches were conducted in MEDLINE, PubMed, Scopus, CINAHL, EMBASE, and PsycINFO for RCTs up to December 2022 inclusive in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Inclusion criteria were RCT study design; participants' mean age ≥ 18 years and ≥ 50% had MSTBI; examined ≥ 1 pharmacological intervention(s), either alone or in combination with other interventions.

Naphthalene dianhydride organic anode for a 'rocking-chair' zinc-proton hybrid ion battery.

Rechargeable batteries consisting of a Zn metal anode and a suitable cathode coupled with a Zn ion-conducting electrolyte are recently emerging as promising energy storage devices for stationary applications. However, the formation of high surface area Zn (HSAZ) architectures on the metallic Zn anode deteriorates their performance upon prolonged cycling. In this work, we demonstrate the application of 1,4,5,8-naphthalenetetracarboxylic dianhydride (NTCDA), an organic compound, as a replacement for the Zn-metal anode enabling the design of a 'rocking-chair'zinc-proton hybrid ion battery.

An In Situ Cross-Linked Nonaqueous Polymer Electrolyte for Zinc-Metal Polymer Batteries and Hybrid Supercapacitors.

This work reports the facile synthesis of nonaqueous zinc-ion conducting polymer electrolyte (ZIP) membranes using an ultraviolet (UV)-light-induced photopolymerization technique, with room temperature (RT) ionic conductivity values in the order of 10 S cm . The ZIP membranes demonstrate excellent physicochemical and electrochemical properties, including an electrochemical stability window of >2.4 V versus Zn|Zn and dendrite-free plating/stripping processes in symmetric Zn||Zn cells.

Two rare presentations of epidermal cyst.

Epidermal cysts are very rare. It is more common in males than in females and the most common site of presentation are the hairy sites. We came across two rare cases of epidermal cysts.
