Mathematics education: new perspectives on gender

mathematics education

Leder G, Forgasz H.
GSID: k-aD9wKshp0J
G Leder, H Forgasz - Zdm, 2008 - Springer

Concern about the education of females is long standing. Over three centuries ago, for example, the English author Daniel Defoe wrote: I have often thought of it as one of the most barbarous customs in the world that we...

Engineering educators have, in the past, shrugged off too easily any blame for the abysmally low numbers of women students going through their schools. The fact that girls often do not …

The structural and chemical origin of the oxygen redox activity in layered and cation-disordered Li-excess cathode materials.

Nature chemistry

Seo DH, Lee J, Urban A, Malik R, Kang S, Ceder G.
PMID: 27325096
Nat Chem. 2016 Jul;8(7):692-7. doi: 10.1038/nchem.2524. Epub 2016 May 30.

Lithium-ion batteries are now reaching the energy density limits set by their electrode materials, requiring new paradigms for Li(+) and electron hosting in solid-state electrodes. Reversible oxygen redox in the solid state in particular has the potential to enable...

Thermodynamics of Phase Selection in MnO.

Journal of the American Chemical Society

Kitchaev DA, Dacek ST, Sun W, Ceder G.
PMID: 28140575
J Am Chem Soc. 2017 Feb 22;139(7):2672-2681. doi: 10.1021/jacs.6b11301. Epub 2017 Feb 13.

While control over crystal structure is one of the primary objectives in crystal growth, the present lack of predictive understanding of the mechanisms driving structure selection precludes the predictive synthesis of polymorphic materials. We address the formation of off-stoichiometric...

Electrolyte-Induced Surface Transformation and Transition-Metal Dissolution of Fully Delithiated LiNi.

Langmuir. 2017 Sep 19;33(37):9333-9353. doi: 10.1021/acs.langmuir.7b00863. Epub 2017 Jun 22.

Enabling practical utilization of layered R3̅m positive electrodes near full delithiation requires an enhanced understanding of the complex electrode-electrolyte interactions that often induce failure. Using Li[Ni

Mitigating oxygen loss to improve the cycling performance of high capacity cation-disordered cathode materials.

Nature communications

Lee J, Papp JK, Clément RJ, Sallis S, Kwon DH, Shi T, Yang W, McCloskey BD, Ceder G.
PMID: 29042560
Nat Commun. 2017 Oct 17;8(1):981. doi: 10.1038/s41467-017-01115-0.

Recent progress in the understanding of percolation theory points to cation-disordered lithium-excess transition metal oxides as high-capacity lithium-ion cathode materials. Nevertheless, the oxygen redox processes required for these materials to deliver high capacity can trigger oxygen loss, which leads...

Odyssey of Multivalent Cathode Materials: Open Questions and Future Challenges.

Chemical reviews

Canepa P, Sai Gautam G, Hannah DC, Malik R, Liu M, Gallagher KG, Persson KA, Ceder G.
PMID: 28269988
Chem Rev. 2017 Mar 08;117(5):4287-4341. doi: 10.1021/acs.chemrev.6b00614. Epub 2017 Feb 13.

The rapidly expanding field of nonaqueous multivalent intercalation batteries offers a promising way to overcome safety, cost, and energy density limitations of state-of-the-art Li-ion battery technology. We present a critical and rigorous analysis of the increasing volume of multivalent...

Reaction of five-membered zirconacycloallenoids with the strong Lewis acid B(C6F5)3.

Dalton transactions (Cambridge, England : 2003)

Bender G, Daniliuc CG, Wibbeling B, Kehr G, Erker G.
PMID: 25010740
Dalton Trans. 2014 Aug 28;43(32):12210-3. doi: 10.1039/c4dt01137f.

Two alkyl and aryl substituted five-membered zirconacycloallenoids underwent a typical σ-alkyl metallocene reaction with B(C6F5)3, namely cleavage of the Zr-C(sp(3)) bond with formation of zwitterionic (η(2)-allenyl)zirconium/alkylborate products. Both products were characterized by X-ray crystal structural analyses.
