Metal nanoparticle catalysts decorated with metal oxide clusters.

Chemical communications (Cambridge, England)

Mashayekhi NA, Wu YY, Kung MC, Kung HH.
PMID: 22945251
Chem Commun (Camb). 2012 Oct 18;48(81):10096-8. doi: 10.1039/c2cc34885c.

Au nanoparticles decorated with mononuclear Ti-oxo units dispersed in silica clusters were formed by activating Au nanoparticles (~2 nm) stabilized with Ti- and amine-functionalized siloxane oligomers. These Au nanoparticles were active catalysts for selective oxidation of propane to acetone,...

Bis(mandelato)borate: an effective, inexpensive spiroborate anion for chiral resolution.

Chemical communications (Cambridge, England)

Wong LW, Kan JW, Nguyen TH, Sung HH, Li D, Au-Yeung AS, Sharma R, Lin Z, Williams ID.
PMID: 26369891
Chem Commun (Camb). 2015 Nov 11;51(87):15760-3. doi: 10.1039/c5cc04977f.

Bis(mandelato)borate [B(Man)2](-) (R- or S-) anions are simply prepared and appear widely effective for resolution of racemic cations. Three examples demonstrate their scope; the alkaloid tetrahydropalmatine (THP), 1,2-diaminopropane (1,2-dap) and the metal-organic complex [Co(phen)3](3+) are readily resolved, either by...

Nanotechnology. 2017 Oct 05; doi: 10.1088/1361-6528/aa9172. Epub 2017 Oct 05.

Over the past few years, two-dimensional (2D) nanomaterials, such as MoS2, have been widely considered as the promising channel materials for next-generation high-performance phototransistors. However, their device performances are still mostly suffered from the slow photoresponse (e.g. with the...

Heterometallic Ce(IV)/M (M = Mo(VI), Re(VII), V(V)) oxo clusters supported by the Kläui tripodal oxygen ligand [(η(5)-C5H5)Co{P(O)(OEt)2}3](-) (LOEt(-)) have been synthesized and structurally characterized, and the catalytic activity of the Ce(IV)/V(V) oxo cluster in the oxidation of thioanisoles has...

Intrinsic Polarization and Tunable Color of Electroluminescence from Organic Single Crystal-based Light-Emitting Devices.

Scientific reports

Ding R, Feng J, Zhou W, Zhang XL, Fang HH, Yang T, Wang HY, Hotta S, Sun HB.
PMID: 26207723
Sci Rep. 2015 Jul 24;5:12445. doi: 10.1038/srep12445.

A single crystal-based organic light-emitting device (OLED) with intrinsically polarized and color-tunable electroluminescence (EL) has been demonstrated without any subsequent treatment. The polarization ratio of 5:1 for the transversal-electric (TE) and transversal-magnetic (TM) polarization at the emission peak of...

2014 Guidelines of Taiwan Society of Cardiology (TSOC) for the Management of Pulmonary Arterial Hypertension.

Acta Cardiologica Sinica

PMID: 27122817
Acta Cardiol Sin. 2014 Sep;30(5):401-44.

UNLABELLED: Pulmonary hypertension (PH) is a hemodynamic and pathophysiologic condition, defined as a mean pulmonary arterial pressure exceeding 25 mmHg at rest. According to the recent classifications, it is grouped into pulmonary arterial hypertension (PAH), heart-related, lung-related, thromboembolic, and...

Nat Commun. 2017 Jun 21;8:15894. doi: 10.1038/ncomms15894.

Low modulus, compliant systems of sensors, circuits and radios designed to intimately interface with the soft tissues of the human body are of growing interest, due to their emerging applications in continuous, clinical-quality health monitors and advanced, bioelectronic therapeutics....

Electrical tunability due to coalescence of exceptional points in parity-time symmetric waveguides.

Optics letters

Wang J, Dong HY, Wu RP, Mok TC, Fung KH.
PMID: 28146521
Opt Lett. 2017 Feb 01;42(3):535-538. doi: 10.1364/OL.42.000535.

We demonstrate theoretically the electric tunability due to the coalescence of exceptional points in PT-symmetric waveguides bounded by imperfect conductive layers. Owing to the competition effect of multimode interaction, multiple exceptional points and PT phase transitions could be attained...

Topological edge plasmon modes between diatomic chains of plasmonic nanoparticles.

We study the topological edge plasmon modes between two "diatomic" chains of identical plasmonic nanoparticles. Zak phase for longitudinal plasmon modes in each chain is calculated analytically by solutions of macroscopic Maxwell's equations for particles in quasi-static dipole approximation....
