Two families of copper lanthanide phosphonate clusters have been obtained through reaction of [Cu2(O2C(t)Bu)4(HO2C(t)Bu)2] and either Ln(NO3)3·nH2O or [Ln2(O2C(t)Bu)6(HO2C(t)Bu)6] and tert-butylphosphonic acid or an amino-functionalized phosphonic acid. The clusters, with general formula [Cu(MeCN)4][Cu3Ln9(μ3-OH)7(O3P(t)Bu)6(O2C(t)Bu)15] and [Cu6Ln6(μ3-OH)6(O3PC(NH2)Me2)6(O2C(t)Bu)12], were structurally characterized through...

The spin dynamics of Cr8 Mn, a nine-membered antiferromagnetic (AF) molecular nanomagnet, are investigated. Cr8 Mn is a rare example of a large odd-membered AF ring, and has an odd-number of 3d-electrons present. Odd-membered AF rings are unusual and...

BACKGROUND: Enteral nutrition (EN) is a widely used, standard-of-care technique for nutrition support in critically ill and trauma patients.OBJECTIVE: To review the current techniques of gastrointestinal tract access for EN.METHODS: For this traditional narrative review, we accessed English-language articles...

Large-region acoustic source mapping using a movable array and sparse covariance fitting.

The Journal of the Acoustical Society of America

Zhao S, Tuna C, Nguyen TN, Jones DL.
PMID: 28147604
J Acoust Soc Am. 2017 Jan;141(1):357. doi: 10.1121/1.4974054.

Large-region acoustic source mapping is important for city-scale noise monitoring. Approaches using a single-position measurement scheme to scan large regions using small arrays cannot provide clean acoustic source maps, while deploying large arrays spanning the entire region of interest...

Molecular and electronic structure of terminal and alkali metal-capped uranium(V) nitride complexes.

Nature communications

King DM, Cleaves PA, Wooles AJ, Gardner BM, Chilton NF, Tuna F, Lewis W, McInnes EJL, Liddle ST.
PMID: 27996007
Nat Commun. 2016 Dec 20;7:13773. doi: 10.1038/ncomms13773.

Determining the electronic structure of actinide complexes is intrinsically challenging because inter-electronic repulsion, crystal field, and spin-orbit coupling effects can be of similar magnitude. Moreover, such efforts have been hampered by the lack of structurally analogous families of complexes...

INTRODUCTION: Relapses of multiple sclerosis (MS) are usually treated with high-dose intravenous methylprednisolone (IVMP), given over 3-10 days. There is no consensus on the optimal duration of treatment. In this study, we aimed to investigate whether longer treatment provides...

Coherent optomechanical state transfer between disparate mechanical resonators.

Nature communications

Weaver MJ, Buters F, Luna F, Eerkens H, Heeck K, de Man S, Bouwmeester D.
PMID: 29018193
Nat Commun. 2017 Oct 10;8(1):824. doi: 10.1038/s41467-017-00968-9.

Systems of coupled mechanical resonators are useful for quantum information processing and fundamental tests of physics. Direct coupling is only possible with resonators of very similar frequency, but by using an intermediary optical mode, non-degenerate modes can interact and...
