Modulating the Evolution of Metastable CaO* for the Near‐Theoretical Performance Breakthrough of Ni/CeO2‐CaO in Integrated CO2 Capture and Methanation

Advanced Science, EarlyView.
A low‐temperature hydrogen spillover decomposition strategy is proposed to reveal the influence of the CaCO3 parent conversion process on the properties of nascent CaO. Under the guidance of the advanced synthesis strategy, the properties of calcium‐based dual‐functional materials are maximally exploited.

Sustainability of cities under declining population and decreasing distance frictions: The case of Japan [PDF]

arXiv
This study develops a statistical model that integrates economic agglomeration theory and power-law distributions of city sizes to project future population distribution on 1-km grid cells. We focus on Japan -- a country at the forefront of rapid population decline.

The Study of the Effects of Economies of Industrial Agglomeration on Economic Growth in Iran’s Provinces [PDF]

پژوهشهای اقتصادی, 2016
In urban and regional economics’ literature, according to the concepts of new economic geography model (NEG) and endogenous growth model, spatial agglomeration of economic activities and economic growth are interrelated processes.

A New Quasi‐Solid Polymer Electrolyte for Next‐Generation Na–O2 Batteries: Unveiling the Potential of a Polyamide‐Polyether System

Advanced Science, EarlyView.
This study introduces a novel, sustainable Pebax1657‐based quasi‐solid polymer electrolyte (QSPE) that enhances the performance and safety of sodium–oxygen (Na–O2) batteries. The developed QSPE shows improved Na+ ion transport, reduced overpotentials, and better cycling stability compared to the conventional liquid systems, highlighting its potential ...

Quantitative characterization of hydrophobic agglomeration at different mixing intensities using a copula-based probabilistic modeling approach [PDF]

arXiv
The agglomeration of small poorly wetted alumina particles in a stirred tank is investigated. For different experimental conditions, two bivariate probability densities for the area-equivalent diameter and aspect ratio of primary particles and agglomerates, respectively, are determined, using 2D image data from an inline camera system.

Adaptive Catalytic Nanointerfaces for Controlled Hydrogen Evolution: an in Situ Electrochemical Approach

Advanced Science, EarlyView.
The ability to switch the HER activity of precious metals at will through a reconfigurable step‐edge/nanoparticle interface, using sulfur as an inorganic mediator, is demonstrated for the first time. This methodology addresses the durability issue of highly catalytic precious metals, which are typically single‐use, thereby extending their lifespan ...
