Homogeneity of doping with paramagnetic ions by NMR.

Physical chemistry chemical physics : PCCP

Li W, Celinski VR, Weber J, Kunkel N, Kohlmann H, Schmedt auf der Günne J.
PMID: 27003194
Phys Chem Chem Phys. 2016 Apr 14;18(14):9752-7. doi: 10.1039/c5cp07606d. Epub 2016 Mar 22.

In NMR, paramagnetic dopants change the relaxation behavior and the chemical shift of the nuclei in their immediate environment. Based on the concept that the "immediate environment" in a diamagnetic host material can be described as a sphere with...

Thermodynamic laws in isolated systems.

Physical review. E, Statistical, nonlinear, and soft matter physics

Hilbert S, Hänggi P, Dunkel J.
PMID: 25615053
Phys Rev E Stat Nonlin Soft Matter Phys. 2014 Dec;90(6):062116. doi: 10.1103/PhysRevE.90.062116. Epub 2014 Dec 09.

The recent experimental realization of exotic matter states in isolated quantum systems and the ensuing controversy about the existence of negative absolute temperatures demand a careful analysis of the conceptual foundations underlying microcanonical thermostatistics. Here we provide a detailed...

Implementing a Veteran-Centered Community Health Clinical Experience in a Baccalaureate Nursing Program.

The Journal of nursing education

Champlin BE, Kunkel DE.
PMID: 28263359
J Nurs Educ. 2017 Mar 01;56(3):186-190. doi: 10.3928/01484834-20170222-12.

BACKGROUND: In a baccalaureate nursing curriculum, students focused on the unique health care needs of veterans and their families. The learning experiences aimed to equip them with the knowledge, skills, and attitudes (KSAs) to provide holistic relation-centered care to...

Defect formation dynamics in curved elastic surface crystals.

Soft matter

Stoop N, Dunkel J.
PMID: 29487938
Soft Matter. 2018 Mar 28;14(12):2329-2338. doi: 10.1039/c7sm02233f. Epub 2018 Feb 28.

Topological defects shape the material and transport properties of physical systems. Examples range from vortex lines in quantum superfluids, defect-mediated buckling of graphene, and grain boundaries in ferromagnets and colloidal crystals, to domain structures formed in the early universe....

Electronic structure of ternary rhodium hydrides with lithium and magnesium.

Inorganic chemistry

Becker JN, Bauer J, Giehr A, Chu PI, Kunkel N, Springborg M, Kohlmann H.
PMID: 24372174
Inorg Chem. 2014 Jan 21;53(2):1135-43. doi: 10.1021/ic402687p. Epub 2013 Dec 27.

Chemical bonding in and electronic structure of lithium and magnesium rhodium hydrides are studied theoretically using DFT methods. For Li3RhH4 with planar complex RhH4 structural units, Crystal Orbital Hamilton Populations reveal significant Rh−Rh interactions within infinite one-dimensional ∞ 1...

Meaning of temperature in different thermostatistical ensembles.

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

Hänggi P, Hilbert S, Dunkel J.
PMID: 26903095
Philos Trans A Math Phys Eng Sci. 2016 Mar 28;374(2064):20150039. doi: 10.1098/rsta.2015.0039.

Depending on the exact experimental conditions, the thermodynamic properties of physical systems can be related to one or more thermostatistical ensembles. Here, we survey the notion of thermodynamic temperature in different statistical ensembles, focusing in particular on subtleties that...

Innovations in science and scenarios for assessment.

Climatic change

Kunkel KE, Moss R, Parris A.
PMID: 27397947
Clim Change. 2016;135:55-68. doi: 10.1007/s10584-015-1494-z. Epub 2015 Aug 29.

Scenarios for the Third National Climate Assessment (NCA3) were produced for physical climate and sea level rise with substantial input from disciplinary and regional experts. These scenarios underwent extensive review and were published as NOAA Technical Reports. For land...

Variation of the Eu(II) emission wavelength by substitution of fluoride by hydride in fluorite-type compounds EuH(x)F(2-x) (0.20 ≤ x ≤ 0.67).

Inorganic chemistry

Kunkel N, Meijerink A, Kohlmann H.
PMID: 24806073
Inorg Chem. 2014 May 19;53(10):4800-2. doi: 10.1021/ic500744s. Epub 2014 May 07.

Mixed-hydride fluorides EuHxF2-x were prepared by the solid-state reaction of EuF2 and EuH2 under hydrogen gas pressure in an autoclave. Eu(II) luminescence is observed for 0.20 ≤ x ≤ 0.67, while pure EuF2 does not show any emission. The...

Perpendicular spin orientation in ultrasmall Fe islands on W(110).

Physical review letters

Röhlsberger R, Bansmann J, Senz V, Jonas KL, Bettac A, Leupold O, Rüffer R, Burkel E, Meiwes-Broer KH.
PMID: 11415310
Phys Rev Lett. 2001 Jun 11;86(24):5597-600. doi: 10.1103/PhysRevLett.86.5597.

We have studied the magnetism of Ag-coated Fe islands on W(110) by nuclear resonant scattering of synchrotron radiation at the 14.4 keV resonance of (57)Fe. Separated islands with an average diameter of 2.0 nm and monolayer thickness are formed...
