In a significant development for sustainable technology, scientists have discovered a method to transform waste oil into a powerful material for energy storage, creating nitrogen-doped hierarchical porous carbons (HPCs) specifically designed for supercapacitors. This innovative template-free approach, developed by researchers at the University of Shanghai for Science and Technology and Tongji University, produces HPCs with enhanced conductivity and electrochemical performance, marking a meaningful step forward in the pursuit of efficient, eco-friendly energy storage solutions.

Can financial subsidy increase electric vehicle (EV) penetration—evidence from a quasi-natural experiment
Abstract Electric vehicles (EVs) are considered a promising solution for reducing emissions in urban transportation and addressing energy crises. Several countries, including China, have implemented direct financial subsidies to encourage the adoption of EVs. However, there is a lack of…
Rapid Joule-heating synthesis of metal/carbon-based electrocatalysts for efficient carbon dioxide reduction
In comparison with conventional pyrolysis processes, the researchers developed a rapid thermal shock method to achieve a uniform dispersion of metal nanoparticles on carbon supports. This approach effectively prevented nanoparticle aggregation, ensuring the full utilization of active sites.
What Was Behind the 2021-2022 Energy Crisis Within Europe?
A team of researchers had already been working with electricity price data for years before Russia’s invasion of Ukraine, exploring statistics and developing forecasting methods. Now they zero in on how prices in different countries relate and how countries were affected by the energy crisis and address the interdependencies of different markets.
Why natural gas is not a bridge technology
The study was headed by Professor Claudia Kemfert from the German Institute for Economic Research (DIW) and Leuphana University Lüneburg in collaboration with Franziska Hoffart from Ruhr-Universität Bochum, Fabian Präger from Technische Universität Berlin and Isabell Braunger and Hanna Brauers from the University of Flensburg.
