Pathway to the identification of C60+ in diffuse interstellar clouds.

Philosophical transactions. Series A, Mathematical, physical, and engineering sciences

Maier JP, Campbell EK.
PMID: 27501976
Philos Trans A Math Phys Eng Sci. 2016 Sep 13;374(2076). doi: 10.1098/rsta.2015.0316.

The origin of the attenuation of starlight in diffuse clouds in interstellar space at specific wavelengths ranging from the visible to the near-infrared has been unknown since the first astronomical observations around a century ago. The absorption features, termed...

Temperature dependence of the conversion efficiency of photochromic perylene bisimide dithienylcyclopentene triads embedded in a polymer.

Physical chemistry chemical physics : PCCP

Thurn J, Maier J, Pärs M, Gräf K, Thelakkat M, Köhler J.
PMID: 28926050
Phys Chem Chem Phys. 2017 Oct 04;19(38):26065-26071. doi: 10.1039/c7cp03634e.

Photochromic molecules that are covalently linked to a strong fluorophore combine the requirements of external control and strong fluorescence, which will become increasingly important for super-resolution microscopy techniques based on single molecules. However, given the bulky structure of such...

Electrochemical Circuit Elements.

PMID: 27640384
Acta Chim Slov. 2016;63(3):578-82. doi: 10.17344/acsi.2016.2398.

The vast majority of electrochemical processes can be modelled by resistors and capacitors. These will then be, in addition to usual circuit elements, electrochemical and chemical resistors or chemical capacitors. The paper shows the significance of understanding these parameters...

A Lamellar Hybrid Assembled from Metal Disulfide Nanowall Arrays Anchored on a Carbon Layer: In Situ Hybridization and Improved Sodium Storage.

Advanced materials (Deerfield Beach, Fla.)

Ding YL, Kopold P, Hahn K, van Aken PA, Maier J, Yu Y.
PMID: 27358115
Adv Mater. 2016 Sep;28(35):7774-82. doi: 10.1002/adma.201602009. Epub 2016 Jun 30.

A lamellar hybrid assembled from metal disulfide (MoS2 , WS2 ) nanowall arrays anchored on nitrogen-doped carbon layers is developed via an in situ hybridization strategy through a synergistic pyrolysis reaction of thiourea and oxometalates. Such a hybrid provides...

Dual-Functionalized Double Carbon Shells Coated Silicon Nanoparticles for High Performance Lithium-Ion Batteries.

Advanced materials (Deerfield Beach, Fla.)

Chen S, Shen L, van Aken PA, Maier J, Yu Y.
PMID: 28295665
Adv Mater. 2017 Jun;29(21). doi: 10.1002/adma.201605650. Epub 2017 Mar 15.

To address the challenge of huge volume change and unstable solid electrolyte interface (SEI) of silicon in cycles, causing severe pulverization, this paper proposes a "double-shell" concept. This concept is designed to perform dual functions on encapsulating volume change...

Deliberate Switching of Single Photochromic Triads.

Scientific reports

Maier J, Pärs M, Weller T, Thelakkat M, Köhler J.
PMID: 28139764
Sci Rep. 2017 Jan 31;7:41739. doi: 10.1038/srep41739.

Photochromic molecules can be reversibly converted between two bistable conformations by light, and are considered as promising building blocks in novel macromolecular structures for sensing and imaging techniques. We have studied individual molecular triads consisting of two strong fluorophores...

"Job-Sharing" Storage of Hydrogen in Ru/Li₂O Nanocomposites.

Nano letters

Fu L, Tang K, Oh H, Manickam K, Bräuniger T, Chandran CV, Menzel A, Hirscher M, Samuelis D, Maier J.
PMID: 25915434
Nano Lett. 2015 Jun 10;15(6):4170-5. doi: 10.1021/acs.nanolett.5b01320. Epub 2015 May 20.

A "job-sharing" hydrogen storage mechanism is proposed and experimentally investigated in Ru/Li2O nanocomposites in which H(+) is accommodated on the Li2O side, while H(-) or e(-) is stored on the side of Ru. Thermal desorption-mass spectroscopy results show that...

Electronic spectra of oxygen containing polycyclic hydrocarbon cations and the protonated analogues.

The Journal of chemical physics

Chakraborty A, Fulara J, Maier JP.
PMID: 26328848
J Chem Phys. 2015 Aug 28;143(8):084312. doi: 10.1063/1.4929484.

The electronic transitions of 9-fluorenone FL(+) and 2,3,6,7-dibenzotropone DBT(+) cations were detected in 6 K neon matrices following a mass-selective deposition. The absorptions at 649.2 and 472.2 nm are assigned to the 2 (2)B1←X̃(2)A2 FL(+) and 2(2)A(')←X̃(2)A(') DBT(+) transitions....

Clinical and radiological repercussions of plexiform neurofibroma in the pelvic region.
