We report a molecular crystal that exhibits four successive phase transitions under hydro-static pressure, driven by aurophilic interactions, with the ground-state structure re-emerging at high pressure. The effect of pressure on two polytypes of tris(μ

Scientific reports

Shirakashi Z, Goto T, Takagi H, Nakamura Y, Lim PB, Uchida H, Inoue M.
PMID: 28993640
Sci Rep. 2017 Oct 09;7(1):12835. doi: 10.1038/s41598-017-12442-z.

Hologram memory is expected to be the next-generation of optical data storage technology. Bismuth-substituted yttrium iron garnet is typically used for rewritable magnetic hologram media. The diffraction efficiency of magnetic holography depends on the Faraday rotation angle, but the...

Mutable Properties of Nonheme Iron(III)-Iodosylarene Complexes Result in the Elusive Multiple-Oxidant Mechanism.

Journal of the American Chemical Society

Kang Y, Li XX, Cho KB, Sun W, Xia C, Nam W, Wang Y.
PMID: 28524647
J Am Chem Soc. 2017 Jun 07;139(22):7444-7447. doi: 10.1021/jacs.7b03310. Epub 2017 May 24.

Although nonheme iron(III)-iodosylarene complexes present amazing oxidative efficiency and selectivity, the nature of such complexes and related oxidation mechanism are still unsolved after decades of experimental efforts. Density functional calculations were employed to explore the structure-reactivity relationship of the...

Highly Stable Three-Dimensional Porous Nickel-Iron Nitride Nanosheets for Full Water Splitting at High Current Densities.

Chemistry (Weinheim an der Bergstrasse, Germany)

Yan F, Wang Y, Li K, Zhu C, Gao P, Li C, Zhang X, Chen Y.
PMID: 28590063
Chemistry. 2017 Jul 26;23(42):10187-10194. doi: 10.1002/chem.201701662. Epub 2017 Jul 04.

A noble-metal-free and highly efficient bifunctional catalyst for overall water splitting is greatly desirable to generate clean and sustainable energy carriers such as hydrogen, but enormous challenges remain. Herein, porous interconnected iron-nickel nitride nanosheets are designed and grown on...

Signal enhancement in cantilever magnetometry based on a co-resonantly coupled sensor.

Beilstein journal of nanotechnology

Körner J, Reiche CF, Gemming T, Büchner B, Gerlach G, Mühl T.
PMID: 27547621
Beilstein J Nanotechnol. 2016 Jul 18;7:1033-43. doi: 10.3762/bjnano.7.96. eCollection 2016.

Cantilever magnetometry is a measurement technique used to study magnetic nanoparticles. With decreasing sample size, the signal strength is significantly reduced, requiring advances of the technique. Ultrathin and slender cantilevers can address this challenge but lead to increased complexity...

Multiwalled carbon nanotube hybrids as MRI contrast agents.

Beilstein journal of nanotechnology

Kuźnik N, Tomczyk MM.
PMID: 27547627
Beilstein J Nanotechnol. 2016 Jul 27;7:1086-103. doi: 10.3762/bjnano.7.102. eCollection 2016.

Magnetic resonance imaging (MRI) is one of the most commonly used tomography techniques in medical diagnosis due to the non-invasive character, the high spatial resolution and the possibility of soft tissue imaging. Contrast agents, such as gadolinium complexes and...

Polymorphism of a chiral iron(ii) complex: spin-crossover and ferroelectric properties.

Dalton transactions (Cambridge, England : 2003)

Han WK, Qin LF, Pang CY, Cheng CK, Zhu W, Li ZH, Li Z, Ren X, Gu ZG.
PMID: 28590481
Dalton Trans. 2017 Jun 27;46(25):8004-8008. doi: 10.1039/c7dt01634d.

Two solvent-free polymorphs of a chiral iron(ii) complex have been obtained, and their polymorphism dependent spin-crossover and ferroelectric properties have been demonstrated. Polymorph I shows a gradual spin-crossover behavior, whereas polymorph II remains in a high-spin state but shows...

Controlled generation of highly saddled (porphyrinato)iron(III) iodide, tri-iodide and one-electron oxidized complexes.

Chemical communications (Cambridge, England)

Sahoo D, Rath SP.
PMID: 26435362
Chem Commun (Camb). 2015 Dec 07;51(94):16790-3. doi: 10.1039/c5cc07111a.

For the first time, three iron(III) porphyrinato complexes have been synthesized selectively by varying the iodine concentration in the reaction mixture which eventually forms both five and six coordinate complexes with iodide and/or tri-iodide as axial ligands. Combined analysis...
