Lattice Distortion‐Driven Metal Exsolution in Perovskite Oxides

Advanced Science, EarlyView.
This study elucidates the mechanism of lattice distortion‐driven exsolution through a combination of computational simulations and experimental approaches. Lattice distortion facilitates the formation of oxygen vacancies and subsequent metal segregation, thereby enhancing the exsolution behavior.

Coupling natural-social models can better quantify the interactions in achieving carbon neutrality in China

Environmental Research Letters
Human activities have greatly altered Earth’s radiative balance, necessitating assessments that couple natural and social systems to address the resulting impacts and interactions. However, traditional Earth System Models (ESMs) and integrated assessment

Efficient Direct Recycling of Spent Batteries: Integrated Lithiation and Delamination

Advanced Science, EarlyView.
An integrated process for the delamination and relithiation of spent cathodes, LixNi0.6Co0.2Mn0.2O2 and LixFePO4, under open‐air conditions is proposed. The transition‐metal (Ni) oxidation state in the cathode is reduced by the oxidation of diethylene glycol, facilitating relithiation. Glycol aldehyde formation induces 100% electrode delamination.

Construction of Sabatier Volcanoes for CO2 Hydrogenation to C1‐2 Oxygenates Using Data‐Efficient Machine Learning

Advanced Science, EarlyView.
A new data‐efficient framework combining DFT calculations, a neural network model, and automated graph analysis of catalytic reaction networks is proposed and applied to CO2 hydrogenation on transition metal nanoparticles. The analysis shows how efficient C2 oxygenate production requires a balance between CHx formation, C–C coupling, protonation, and ...

Effort at Constructing Big Data Sensor Networks for Monitoring Greenhouse Gas Emission

International Journal of Distributed Sensor Networks, 2014
Global warming is an important environment issue rapidly becoming a part of popular culture. Scientists are 95–100% certain that it is primarily caused by increasing concentrations of greenhouse gases produced by human activities.

Thermally Processable, Transparent, Mechanically Tunable and Robust Bioplastics From Wastepaper

Advanced Science, EarlyView.
Unlike conventional inefficient or low‐value wastepaper recycling, a directional transformation strategy is employed to convert whole wastepaper into intact bioplastics with tunable mechanical properties in our work. These bioplastics can be processed into flexible bags or rigid containers and exhibit high transparency, water resistance, repairability,

China is a Key to Mitigate Global Climate Change

Andalas Journal of International Studies, 2015
This paper attempts to discuss China’s response on the global climate change. China, well known as the world’s largest emitter of greenhouse gases, the largest energy consumer and the second largest economy in the world, contributes for a third of the ...

Closed‐Loop Radiative Cooling Mulch Upcycled From Agricultural Residues for Efficient Soil Heat–Water Stress Mitigation

Advanced Science, EarlyView.
Conventional passive radiative cooling films rely on costly feedstocks and energy‐intensive fabrication, with poor end‐of‐life compatibility in agriculture. To address this challenge, a sustainable radiative cooling mulch (SRCM) is developed from waste maize leaves via spontaneous hydrogen‐bond self‐assembly.

Re-assessment of net energy production and greenhouse gas emissions avoidance after 40 years of photovoltaics development

Nature Communications, 2016
While the photovoltaic industry aims to achieve cleaner energy production, it consumes energy and emits greenhouse gases during production and deployment. Here, Louwenet al.
