Electrolyte Engineering Challenges and Opportunities for Next‐Generation Aqueous Ammonium‐Ion Batteries

Advanced Materials, EarlyView.
Aqueous ammonium‐ion batteries (AAIBs) face a hydrogen‐bond paradox: the HB network enables fast NH4+ transport but triggers water decomposition. This review dissects this dilemma, evaluates multiple electrolyte engineering strategies, and outlines four future directions for next‐generation AAIB design ABSTRACT Aqueous ammonium‐ion batteries (AAIBs ...

Investigation of Electro‐Oxidation and Ozonation for Removal of Organics in Wastewater Derived From Recycling Process for Lithium‐Ion Batteries

CleanMat, EarlyView.
To develop recycling processes for lithium‐ion batteries, wastewater treatment for the removal of organic compounds originating from the electrolyte was investigated using electro‐oxidation and ozonation. Based on the results, this paper proposes a process which combines these two methods to remove alcohols derived from the solvent and additives ...

Thermal Ignition of ADN‐Based Propellants [PDF]

Propellants, Explosives, Pyrotechnics, 2019
AbstractAmmonium dinitramide (ADN, NH4+ N(NO2)2−) based monopropellants are extremely promising as hydrazine replacement. Thermal igniters are attractive for ADN thrusters as they allow a more prompt ignition and may be better suited for larger engines (100‐500 N) compared to the currently used preheated catalysts.

Verification of False Reactivity in HIV Rapid Diagnostic Tests and Its Translation Into the Three Tests Algorithm in Cameroon

Journal of Clinical Laboratory Analysis, EarlyView.
Verification study enabled the detection of HIV false reactivity ranging from 0‐4% across rapid diagnostic tests. A reliable three‐tests algorithm ranked First Response HIV 1‐2‐0 Card, First Response HIV1+2/Syphilis Combo or STANDARD Q as suitable test 1 to mitigate false positive events. As countries move toward HIV elimination, implementing the three‐
