Universal Electronic‐Structure Relationship Governing Intrinsic Magnetic Properties in Permanent Magnets

open access: yesAdvanced Functional Materials, EarlyView.
Permanent magnets derive their extraordinary strength from deep, universal electronic‐structure principles that control magnetization, anisotropy, and intrinsic performance. This work uncovers those governing rules, examines modern modeling and AI‐driven discovery methods, identifies critical bottlenecks, and reveals electronic fingerprints shared ...

FAMILY SIZE, INCREASING BLOCK TARIFF AND ECONOMIES OF SCALE OF HOUSEHOLD ELECTRICITY CONSUMPTION IN VIETNAM FROM 2010 TO 2014

open access: yesJournal of International Economics and Management, 2018
Household electricity consumption potentially offers economies of scale, since lighting, cooling or cooking can be shared among household members. This idea needs to be tested empirically.

Covalent Organic Frameworks for Photocatalytic CO2 Reduction: Metal Integration Principles, Strategies and Functions

open access: yesAdvanced Functional Materials, EarlyView.
Covalent organic frameworks (COFs) with metals have been recognized as versatile platforms for photocatalytic CO2 reduction (CO2PRR). Herein, an overview of metal integration strategies for COFs is systematically summarized. Regulatory mechanisms and structure–activity relationships between metal integration and COF‐based CO2PRR are emphasized.

Agglomeration Economies: Ambiguities and Confusions [PDF]

open access: yes
The concept of agglomeration economies, first considered in a systematic (though rather restrictive) manner by Weber, has proven to be an important feature in the analysis of industrial location, whether this is of a theoretical or empirical nature.

Bio‐Inspired Molecular Events in Poly(Ionic Liquids)

open access: yesAdvanced Functional Materials, EarlyView.
Originating from dipolar and polar inter‐ and intra‐chain interactions of the building blocks, the topologies and morphologies of poly(ionic liquids) (PIL) govern their nano‐ and micro‐processibility. Modulating the interactions of cation‐anion pairs with aliphatic dipolar components enables the tunability of properties, facilitated by “bottom‐up ...

Scale Externalities of the G7 Countries [PDF]

open access: yes
Scale effects in per capita production are an outcome of many theoretical economic models like second generation growth models, models of the new trade theory or the new economic geography. The prediction is that larger economies should have a higher per

High Energy Density Asymmetric Aqueous Supercapacitor Based on a 2D Manganese Carbide as a Positive Electrode

open access: yesAdvanced Functional Materials, EarlyView.
A circular route, involving upcycling of waste surgical masks, affords a Mn‐based layered carbide with porosity, redox activity and low work function. These features enable its effective operation as positive supercapacitor electrode in an aqueous asymmetric supercapacitor delivering 213 Wh L−1 energy density.

A Simple Model of Dairy Product Supply [PDF]

open access: yes
Dairy products are characterized by two properties, namely, perishability and short-periodic production. These properties are so unique that conventional studies in agricultural economics or in industrial organization might not explain the dairy product ...
