Two-dimensional topological insulators (2D TIs) are a remarkable class of atomically thin layered materials that exhibit unique symmetry-protected helical metallic edge states with an insulating interior. Recent years have seen a tremendous surge in research of this intriguing new...

BACKGROUND: Camelina sativa is an oilseed crop with great potential for biofuel production on marginal land. The seed oil from camelina has been converted to jet fuel and improved fuel efficiency in commercial and military test flights. Hydrogenation-derived renewable...

Modeling CO2 reduction on Pt(111).

Physical chemistry chemical physics : PCCP

Shi C, O'Grady CP, Peterson AA, Hansen HA, Nørskov JK.
PMID: 23552398
Phys Chem Chem Phys. 2013 May 21;15(19):7114-22. doi: 10.1039/c3cp50645b.

Density functional theory was used to model the electrochemical reduction of CO2 on Pt(111) with an explicit solvation layer and the presence of extra hydrogen atoms to represent a negatively charged electrode. We focused on the electronic energy barriers...

Enhancement of chemical stability and crystallinity in porphyrin-containing covalent organic frameworks by intramolecular hydrogen bonds.

Angewandte Chemie (International ed. in English)

Kandambeth S, Shinde DB, Panda MK, Lukose B, Heine T, Banerjee R.
PMID: 24127339
Angew Chem Int Ed Engl. 2013 Dec 02;52(49):13052-6. doi: 10.1002/anie.201306775. Epub 2013 Oct 14.

A strong bond: A strategy based on intramolecular hydrogen-binding interactions in 2D covalent organic frameworks (COFs) is shown to improve the crystallinity, porosity, and chemical stability of the material. The concept is validated by removing the hydrogen-bonding interaction in...

Colloidal synthesis of single-layer MSe2 (M = Mo, W) nanosheets via anisotropic solution-phase growth approach.

Journal of the American Chemical Society

Jung W, Lee S, Yoo D, Jeong S, Miró P, Kuc A, Heine T, Cheon J.
PMID: 26053408
J Am Chem Soc. 2015 Jun 17;137(23):7266-9. doi: 10.1021/jacs.5b02772. Epub 2015 Jun 08.

The generation of single-layer 2-dimensional (2D) nanosheets has been challenging, especially in solution-phase, since it requires highly anisotropic growth processes that exclusively promote planar directionality during nanocrystal formation. In this study, we discovered that such selective growth pathways can...

Exploration of Functional Connectivity During Preferred Music Stimulation in Patients with Disorders of Consciousness.

Frontiers in psychology

Heine L, Castro M, Martial C, Tillmann B, Laureys S, Perrin F.
PMID: 26617542
Front Psychol. 2015 Nov 09;6:1704. doi: 10.3389/fpsyg.2015.01704. eCollection 2015.

Preferred music is a highly emotional and salient stimulus, which has previously been shown to increase the probability of auditory cognitive event-related responses in patients with disorders of consciousness (DOC). To further investigate whether and how music modifies the...

Spectra Transfer Between a Fourier Transform Near-Infrared Laboratory and a Miniaturized Handheld Near-Infrared Spectrometer.

Applied spectroscopy

Hoffmann U, Pfeifer F, Hsuing C, Siesler HW.
PMID: 27170780
Appl Spectrosc. 2016 May;70(5):852-60. doi: 10.1177/0003702816638284.

The aim of this contribution is to demonstrate the transfer of spectra that have been measured on two different laboratory Fourier transform near-infrared (FT-NIR) spectrometers to the format of a handheld instrument by measuring only a few samples with...

Catalytic and hydrodynamic properties of styrene monooxygenases from Rhodococcus opacus 1CP are modulated by cofactor binding.

AMB Express

Riedel A, Heine T, Westphal AH, Conrad C, Rathsack P, van Berkel WJ, Tischler D.
PMID: 26054733
AMB Express. 2015 Dec;5(1):112. doi: 10.1186/s13568-015-0112-9. Epub 2015 Jun 04.

Styrene monooxygenases (SMOs) are flavoenzymes catalyzing the epoxidation of styrene into styrene oxide. SMOs are composed of a monooxygenase (StyA) and a reductase (StyB). The latter delivers reduced FAD to StyA on the expense of NADH. We identified Rhodococcus...

Decoding the Morphological Diversity in Two Dimensional Crystalline Porous Polymers by Core Planarity Modulation.

Angewandte Chemie (International ed. in English)

Halder A, Kandambeth S, Biswal BP, Kaur G, Roy NC, Addicoat M, Salunke JK, Banerjee S, Vanka K, Heine T, Verma S, Banerjee R.
PMID: 26953562
Angew Chem Int Ed Engl. 2016 Jun 27;55(27):7806-10. doi: 10.1002/anie.201600087. Epub 2016 Mar 08.

Two new chemically stable triazine- and phenyl-core-based crystalline porous polymers (CPPs) have been synthesized using a single-step template-free solvothermal route. Unique morphological diversities were observed for these CPPs [2,3-DhaTta (ribbon) and 2,3-DhaTab (hollow sphere)] by simply altering the linker...

Chemistry. 2016 Feb 18;22(8):2708-18. doi: 10.1002/chem.201503725. Epub 2016 Jan 21.

The complexes [MCl2 (TzH)4] (M=Mn (1), Fe (2); TzH=1,2,4-1H-triazole) and [ZnCl2 (TzH)2] (3) have been obtained by mechanochemical reactions of the corresponding divalent metal chloride and 1,2,4-1H-triazole. They were successfully used as precursors for the formation of coordination polymers...
