High‐Index, Low‐Loss Optical Material Platforms for Ultra‐Broadband Ultraviolet‐to‐Visible Achromatic Metalenses

open access: yesAdvanced Functional Materials, EarlyView.
An integrated material platform combining engineered SiNx thin films and printable ZrO2 nanoparticle‐embedded resin enables broadband achromatic metalenses from the ultraviolet to visible range. The demonstrated meta‐optics achieve near‐diffraction‐limited focusing with minimal chromatic aberration.

Convergence and Regional Productivity Divide in Italy: Evidence from Panel Data

open access: yes
: Using a panel data model to control for differences in regional technological levels and to take into account endogeneity, we find two key results for the growth of Italian regions.

Dual‐Salt Carbothermal Shock Strategy Enabling Ultrafast and Sustainable Regeneration of Spent LiFePO4 Cathode Materials

open access: yesAdvanced Functional Materials, EarlyView.
Lithium iron phosphate (LFP) accounts for over 50% of the global cathode market, underscoring the need for efficient recycling and regeneration. We propose a dual‐salt carbothermal shock (CTS) strategy using LiI and NaI to in situ repair Li vacancies.

Regional Inequalities and Economic Convergence in Turkey

open access: yes, 2019
Doğu ve batı bölgeleri arasındaki ciddi düzeydeki bölgesel gelişmişlik farkları politikacıların ve devletin bölgesel gelişme politikalarının temel ilgi alanı ola gelmiştir. Türkiye bu gelişmişlik farklarını azaltmak için bir takım bölgesel gelişme araçları ve mekanizmaları geliştirmiştir. Ancak, 2000'li yıllara kadar uygulanan geleneksel yukarıdan

Interplay Between Phase Evolution, Fe Migration, and Oxygen Redox in O3‐Type NaxFeyMn1−yO2 Cathodes

open access: yesAdvanced Functional Materials, EarlyView.
Why do Na‐ion battery cathodes, that are compositionally closely related, follow different structural paths during battery operation? This work shows how Fe content controls when iron atoms migrate from their original sites. Early migration locks the layers and blocks key phase transitions, whereas delayed migration permits fuller structural ...
