A Closed‐Loop Direct Recycling Process for Prussian White From Scrap and End‐of‐Life Sodium‐Ion Batteries

Advanced Energy Materials, EarlyView.
A closed‐loop direct recycling route for Prussian White sodium‐ion battery cathodes is demonstrated. Ice‐stripped scrap and end‐of‐life electrodes are regenerated via low‐temperature aqueous resodiation (80°C), restoring sodium content, Fe2+ redox chemistry, and structural integrity.

Technical analysis: the psychology of the market of dry bulk freight rates

Journal of Shipping and Trade, 2020
Financial technical analysis of markets and trends differs from fundamental analysis in that econometrics are used on “fundamental” economic data in fundamental analysis.

Monetary Policy with Incomplete Markets [PDF]

We consider an extension of a general equilibrium model with incomplete markets that considers cash-in-advance constraints. The total amount of money is supplied by an authority, which produces at no cost and lends money to agents at short term nominal ...

Ether‐Based Electrolytes and the Solvation Structure in Sodium Ion Batteries

Advanced Energy Materials, EarlyView.
Ether electrolytes enable high‐performance sodium‐ion batteries through their unique physicochemical properties, particularly distinctive solvation structures and co‐intercalation behavior. However, the localized solvation structure and its dynamic evolution during electrochemical processes remain a “black box”.

Nickel‐Free Perovskite Solar Cells Enabled by Self‐Assembled Monolayers: A Pathway to Efficient and Recyclable Devices

Advanced Energy Materials, EarlyView.
Replacing toxic NiOx with phenyl‐substituted phosphonic‐acid carbazole monolayers (Ph‐5PACz) yields inverted perovskite solar cells that are efficient and recyclable. The nickel‐free interface reaches 25.3% efficiency and enables closed‐loop ITO recovery with near‐98% performance retention, while life‐cycle and techno‐economic analyses confirm lower ...

On the Properties of General Equilibrium with Default in Economies with Incomplete Markets [PDF]

In this paper we study the properties of general equilibrium with default in economies with incomplete markets. It is noted that, in equilibrium, an agent makes two types of comparisons when deciding whether to participate in the credit market: as a ...

Coprecipitation‐Enabled Scalable Synthesis of High‐Energy Density Polyanion‐Integrated Disordered Rocksalt Cathodes for Lithium‐Ion Batteries

Advanced Energy Materials, EarlyView.
A coprecipitation‐enabled solid‐state route enables scalable synthesis of the metastable polyanion‐integrated disordered rocksalt cathode, Li1.67Mn1.5P0.17O4, without mechanochemical phase formation or post‐synthesis pulverization. Coprecipitation establishes local Mn–P–O integration in the precursor, while eutectic LiOH/LiNO3‐assisted lithiation ...

Closed-Form Pricing of European Call Options Under a Sub-Mixed Fractional Brownian Motion with Jumps via Three Pricing Approaches

Mathematics
The Black–Scholes model laid the mathematical foundation for modern option pricing; however, its assumptions—stationary, independent, and Gaussian returns—are frequently violated in real markets, where long-memory volatility and sudden price jumps are ...
