Thus, we analyzed the mass and chemical composition variation of EDL within electrochemical operation by electrochemical quartz crystal microbalance, in-situ X-ray photoelectron spectroscopy, and time-of-flight secondary ion mass spectrometry. We found that N-doping triggers specifically adsorbed propylene...
Abstract ( 5 ) PDF (2084KB) ( 2 ) Precisely quantifying transition metal (TM) redox in bulk is a key to understand the fundamental of opti-mizing cathode materials in secondary batteries. At present, the commonly used methods to probe TM redox are hard X-ray absorption spectroscopy (hXAS...
The term “normal” means that the alkane has no branches. If the secondary carbon atom of propane loses a hydrogen atom, a secondary alkyl group known as the isopropyl group is formed. The abbreviations of propyl and isopropyl are n-Pr and i-Pr. Sign in to download full-size image ...
They proposed to adopt the term “rotaxane effect” to identify the large thermodynamic stabilization (reflected in a very low acidity) of the secondary-ammonium moiety due to the strong interaction with the crown ether wheel. The first strategy involved an exchange with a competitive counter ion ...
Green chemistry, also called sustainable chemistry, is a new field that encourages the design and development of chemicals using principles that minimize the use and generation of toxic chemicals. Paul Anastas coined the term “green chemistry,” and it consists of 12 principles that he developed....

Through a hermeneutic phenomenological research perspective, the teaching journal of a first year chemistry teacher was examined to address the question: What is the nature of creating a professional identity of science teacher? We describe three dilemmas the teacher experienced, the metaphors she create...

This work not only presents a far-reaching significance for large-scale recycling of spent LIBs in the future, but also proposed a sustainable and economical method to design new-type secondary batteries as recycling of spent LIBs. Polar interaction of polymer host-solvent enables stable solid ...
Second-life batteries can be used in a wide variety of secondary applications. Second-life batteries can be connected with off-grid or on-grid photovoltaic and wind systems, vehicle charging stations, forklifts, and frequency control. The present work aims to analyze the main challenges imposed ...
