Electron‐Deficient Linkers Enhance H2O2 Electrosynthesis in Covalent Organic Frameworks

open access: yesAdvanced Functional Materials, EarlyView.
Linker π‐conjugation modulates the electronic state of the Ni–N4 centers and their interaction with the key *OOH intermediate while preserving the primary coordination motif. NiPc‐PTDA delivers an H2O2 selectivity of 92% and a production rate of 34.8 mol gcat−1 h−1, highlighting linker electronic properties as a molecular design parameter for NiPc ...

Prospects and problems of increasing electricity production from mid-size (<30 MW) renewable energy generation facilities on the South-West Interconnected System (SWIS) [PDF]

open access: yes, 2011
Western Australia (WA) is truly blessed by abundant and readily available renewable energy resources. Yet most of its energy use still comes from fossil fuel energy. In the case of the South-West Interconnected System (SWIS), which is the largest grid of

Desert Plant Inspired Hierarchical Nanofibrous Membranes for Integrated Solar Desalination and Heavy Metal Remediation

open access: yesAdvanced Functional Materials, EarlyView.
An Alhagi maurorum inspired hierarchical composite membrane (NFCu) was developed by integrating heavy metal remediation and solar‐driven interfacial evaporation in a single platform. Beyond the photothermal effect, a localized photocatalytic process is realized on the CuO surface, deepening the mechanistic understanding of light–matter–water ...

Decoupling the Size and Loading Effects in Silver Nanoparticles for Efficient Paired Carbon Dioxide and Formaldehyde Electrolysis

open access: yesAdvanced Functional Materials, EarlyView.
We investigate size‐dependent CO selectivity on Ag nanoparticles, where optimized Ag loading achieves nearly 100% Faradaic Efficiency for CO at −100 mA·cm−2. In situ SERS and XPS reveal the crucial role of optimized loading in catalytic performance. The Ag/C catalyst further exhibits bifunctional activity, enabling efficient electrolysis of CO2 and ...

The Role of Renewable Gas Energy Communities in Austria’s Energy Transformation

open access: yesEnergies
Renewable energy communities (RECs) can play a vital role in integrating renewable gases like biomethane into Austria’s energy system. This study examines critical gaps in national regulations for renewable gas RECs (short ‘gas RECs’) and the need for ...

CONTRIBUTION TO THE STRUCTURAL STUDY AND PETROLEUM INTEREST OF THE NORTHERN PART OF THE TANGANYIKA BASIN OF THE WESTERN BRANCH OF THE EAST AFRICAN RIFT OF D.R. CONGO [PDF]

open access: yesRomanian Journal of Petroleum & Gas Technology
Discoveries are succeeding each other as oil was perceived, a long time ago, as a rather rare resource in sub-Saharan Africa. Paradoxically, it is found everywhere, from Angola to Guinea-Bissau, then along the entire western coast, notably in Ghana ...

Market Stimulation of Renewable Electricity in the EU: What degree of harmonisation of support mechanisms is required? CEPS Task Force Reports No. 56, 1 October 2005 [PDF]

open access: yes, 2005
Over the last two decades, renewable energy sources (RES) have attracted heightened interest for a number of different reasons. RES promise strategic improvements in the security of supply, reduce the long-term price volatility to which the EU is ...

UK renewable energy policy since privatization [PDF]

open access: yes, 2011
The aim of this paper is to look at the UK’s renewable energy policy in the context of its overall decarbonisation and energy policies. This will allow us to explore the precise nature of the ‘failure’ of UK renewables policy and to suggest policy ...
