The amphiphilic polymers poly[2,5,8,11,14-pentaoxapentadecamethylene(5-hexadecyloxy-1,3-phenylene)] I (abbrev. C16O5), its homologues C16On, n = 1-4, and its copolymers with C16O1 have been synthesised by two Williamson procedures. Method X gives polyether-esters; method Y gives pure polyethers.

We report a quantum-chemical study of the electronic and optical properties of several platinum(II) dimers, [Pt(pip2NCN)]2(L)(2+) (pip2NCNH = 1,3-bis(piperidylmethyl)benzene, L represents the bridging ligands pyrazine, 4,4'-bipyridine, or trans-1,2-bis(4-pyridyl)ethylene). The theoretical calculations reveal that as the pi-conjugated length of bridging...

ESI-FTICR-MS studies on gas phase fragmentation reactions of ArPd(PPh3)2I complexes.

Journal of the American Society for Mass Spectrometry

PMID: 16904338
J Am Soc Mass Spectrom. 2006 Nov;17(11):1582-9. doi: 10.1016/j.jasms.2006.07.009. Epub 2006 Aug 09.

Gas-phase fragmentation reactions of [ArPd(PPh3)2]+ were studied by electrospray ionization Fourier transform ion cyclotron resonance mass spectrometry (ESI-FTICR-MS). The results of sustained off-resonance irradiation collision-activated dissociation (SORI-CAD) experiments provide detailed insights into mechanisms for the gas-phase fragmentation reactions of...

Improvement to human-face recognition in a volume holographic correlator by use of speckle modulation.

Applied optics

Cao L, He Q, Ouyang C, Liao Y, Jin G.
PMID: 15726951
Appl Opt. 2005 Feb 01;44(4):538-45. doi: 10.1364/ao.44.000538.

We show that a speckle-modulation technique can improve the parallelism and the recognition accuracy of volume holographic correlators. The object patterns are modulated by a speckle pattern generated by a diffuser. These modulated patterns are stored as Fourier holograms...

Systematic study of the structure-property relationship of a series of ferrocenyl nonlinear optical chromophores.

Journal of the American Chemical Society

Liao Y, Eichinger BE, Firestone KA, Haller M, Luo J, Kaminsky W, Benedict JB, Reid PJ, Jen AK, Dalton LR, Robinson BH.
PMID: 15725034
J Am Chem Soc. 2005 Mar 02;127(8):2758-66. doi: 10.1021/ja0449123.

A series of novel nonlinear optical (NLO) chromophores 1-4 incorporating the ferrocenyl (Fc) group as an electron donor and 2-dicyanomethylene-3-cyano-4-methyl-2,5-dihydrofuran (TCF) derivatives as electron acceptors are presented. The use of a constant Fc donor and varied acceptors and bridges...

Tuning the field-induced magnetic transition in a layered cobalt phosphonate by reversible dehydration-hydration process.

Chemical communications (Cambridge, England)

Yang TH, Liao Y, Zheng LM, Dinnebier RE, Su YH, Ma J.
PMID: 19462074
Chem Commun (Camb). 2009 Jun 07;(21):3023-5. doi: 10.1039/b903324f. Epub 2009 Apr 09.

A layered cobalt phosphonate, Co(2-pmp)(H(2)O)(2) (1) (2-pmpH(2) = 2-pyridylmethylphosphonic acid) is reported, which provides the first example of metamagnetic cobalt system that shows reversible changes in both structures and magnetic behaviors upon dehydration-hydration process.

NO signaling and S-nitrosylation regulate PTEN inhibition in neurodegeneration.

Molecular neurodegeneration

PMID: 21067594
Mol Neurodegener. 2010 Nov 10;5:49. doi: 10.1186/1750-1326-5-49.

BACKGROUND: The phosphatase PTEN governs the phosphoinositide 3-kinase (PI3K)/Akt signaling pathway which is arguably the most important pro-survival pathway in neurons. Recently, PTEN has also been implicated in multiple important CNS functions such as neuronal differentiation, plasticity, injury and...

Optical metal-oxide tunnel detectors with microstructured electrodes.

Optics letters

Glass AM, Liao PF, Olson DH, Humphrey LM.
PMID: 19714096

Order-of-magnitude improvement of the quantum efficiency of metal-oxide-metal detectors is achieved in the visible spectrum by fabricating the devices on silica substrates structured with a periodic array of bumps separated by about 0.25 microm. Structuring metallic films affords improved...

J Phys Chem A. 2009 Oct 15;113(41):10994-1001. doi: 10.1021/jp902293q.

We investigate the molecular first hyperpolarizability (beta) for donor/acceptor (D/A) substituted pi-conjugated organic molecules with different D/A groups and pi-systems (including up to eight pi-bonds). The results of the MP2 and density functional theory (PBE0, BMK, M05, M05-2X) calculations...

Synergistic effect of silicate clay and phosphazene-oxyalkyleneamines on thermal stability of cured epoxies.

Amine substitution of hexachlorocyclophosphazene (HCP) with poly(oxypropylene)diamines (POP) afforded HCP-POP adducts which were subsequently intercalated into a layered silicate clay. The relative thermal stabilities of the epoxies cured with the phosphazene-amines and the intercalated clays were studied. The organoclays,...
