Designing a learning environment based on the spiral of skills to overcome the didactic obstacles associated with teaching the Daniell cell

Autor: Mennani Mourad, Raouf Khadija, Khyati Abderrahim

Publikováno v: Chemistry Teacher International, Vol 5, Iss 4, Pp 379-395 (2023)

In a teaching context based on the competency approach, the creation of an appropriate teaching-learning environment requires, among other things, teachers to master the meaning of the concepts taught and teaching-learning activities designed accordi

Energy on demand: A brief history of the development of the battery

Autor: Christopher L Heth

Publikováno v: Substantia, Vol 3, Iss 2 (2019)

Portable, readily available electrical energy provided by batteries is ubiquitous in modern society and can easily be taken for granted. From the early Voltaic piles to modern lithium ion cells, batteries have been powering scientific and technologic

Electromotive Force versus Electrical Potential Difference: Approaching (but Not Yet at) Equilibrium

Autor: Luiz H. S. Gasparotto, Leandro da Silva Rodrigues, Jones de Andrade

Publikováno v: Journal of Chemical Education. 95:1811-1815

One of the most elusive concepts in electrochemistry is that of electromotive force (EMF). Often students, and even instructors, mistakenly take it as “electric potential difference” (EPD) or “voltage difference”. To clarify this issue proper

Boosting of the output voltage of a galvanic cell

Autor: Karel Lacina, Petr Vanýsek, Petr Skládal, Jakub Sopoušek

Publikováno v: Electrochimica Acta. 282:331-335

The output voltage of a galvanic cell can be increased by insertion of two pairs of anodes and cathodes into a single volume of an electrolyte. The anode from the first pair and the cathode from the second pair are galvanically connected using extern

Unfolding the Hidden Reactions in Galvanic Cells

Autor: Nicholas A. Payne, Eric Martineau, Tomer Noyhouzer, Janine Mauzeroll, Daphnée Bellemare-Alford

Publikováno v: Electrocatalysis. 9:531-538

The relationship between the potential of the cell reaction (Ecell), the entropy change (ΔS), and the enthalpy change (ΔH) is well established. Yet, there is surprisingly a very narrow range of experimental aqueous galvanic cells that follow thermo

The finding of nickel extraction material: How nickel ferrocyanide offer excess capacity

Autor: Maoting Xia, Ying Xie, Huihui Yan, Haoxiang Yu, Zhen-Bo Wang, Chenchen Deng, Jie Shu, Xikun Zhang, Liyuan Zhang

Publikováno v: Nano Today. 41:101327

In alkali metal ion batteries, insoluble ferrocyanide with few alkali metal ions can provide excess initial charge capacity which is much higher than the contribution from the extraction of alkali metal ions. Why? This commonly encountered fatal prob
