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.

New Forms of Metropolitan Developments: Stockholm in the 20-th century [PDF]

open access: yes, 2003
The main conclusion of this article is that we in many respects can observe new tendencies in the development of Stockholm from the 1970s and on. The population growth rate has for instance been high compared to other Swedish cities, and that was not the

The battle of Detroit and anti-communism in the depression era [PDF]

open access: yes, 2008
This article is an exploration of Diego Rivera's visit to Detroit in 1932-3. It seeks to use his experiences, and in particular the spectacular popular reaction to the Detroit Industry murals he pointed, as a prism for anaylsing varieties of anti ...

Establishing a Model Precursor System: Over a Decade of Research on Carbon Dots from the Citric Acid‐Urea System

open access: yesAdvanced Functional Materials, EarlyView.
The citric acid/urea (CA‐Urea) precursor system offers a versatile, scalable route to carbon dots with tunable luminescence and multifunctionality. Mechanistic insights into precursor chemistry and reaction parameters have enabled doping, surface modification, and hybridization strategies, yielding CDs for luminescent devices, sensing, catalysis ...

Neoliberalism in the Information Age, or Vice Versa? Global Citizenship, Technology, and Hegemonic Ideology

open access: yestripleC: Communication, Capitalism & Critique, 2011
Contingent as they are upon technological globalization, contemporary notions of global citizenship tend to run parallel to theories of ‘post-industrialism’ and ‘information society’.

Toward Stable Multivalent Metal Batteries: Understanding the Interfacial Chemistry for Magnesium and Calcium Metal Anodes

open access: yesAdvanced Functional Materials, EarlyView.
Interphase chemistry governs the stability of multivalent metal batteries. We summarize state‐of‐the‐art developments in calcium and magnesium metal batteries by focusing on the correlation among electrolytes, interphase layers, and the electrochemical performance of corresponding metal anodes.

Der Fortschritt der Kritischen Theorie

open access: yesÖsterreichische Zeitschrift für Geschichtswissenschaften, 2009
Critical Theory in the 1940s contributed a significant modification of the classic idea of ‚progress‘ by arguing that development of the means of production implies development of the means of domination at the same time. This does not (against Habermas)

Balancing Electrons to Break the Activity‐Selectivity Trade‐Off in H2O2 Electrosynthesis

open access: yesAdvanced Functional Materials, EarlyView.
Carrier‐concentration balancing in CuS is achieved by coupling cobalt dopants with cobalt vacancies, converting CuS from p‐ to n‐type to accelerate 2e− ORR while withdrawing excess carriers to optimize *OOH binding for H2O2 desorption. The catalyst reaches 8.14 mol g−1 h−1 with >84% selectivity in 1.0 M KOH and drives robust electro‐Fenton dye ...
