Inorg Chem. 2006 Jun 26;45(13):4880-2. doi: 10.1021/ic060397t.

Dinuclear and cubane-shaped lanthanide cluster complexes containing EuIII)and TbIII were synthesized by step-by-step construction using p-tert-butylsulfonylcalix[4]arene as a cluster-forming ligand. The sulfonylcalixarene adopts a pinched-cone conformation in the dinuclear complexes and a cone conformation in the cubane complexes. Because...

Variable on-demand release function of magnetoresponsive hybrid capsules.

Magnetoresponsive hybrid capsules formed with polyelectrolytes, amphiphile bilayers and Fe(3)O(4) nanoparticles were fabricated by a colloid-templating technique. Melamine-formaldehyde (MF) core particles with polyelectrolyte multilayer shell were prepared by layer-by-layer assembly. Fe(3)O(4) nanoparticles were additionally deposited on the capsular surface....

Immunoglobulin A deficiency (IgAD) is the most common immunodeficiency, but the pathogenesis of most cases of IgAD is poorly understood. The gene and protein expression levels of members of the IgA subclasses in IgAD patients were analyzed by a...

Cascade-connective optical parallel logic processor using electrophotonic devices.

Applied optics

Kawai S, Tashiro Y, Ichinose H, Kasahara K.
PMID: 20717390
Appl Opt. 1992 Jan 10;31(2):178-85. doi: 10.1364/AO.31.000178.

To perform image or arithmetic processing optically, it is necessary that a large number of required optical processors be connected in a series. For such cascade connections, however, coding and decoding processes are undesirable because of the necessity for...

Free-space optical bus using cascaded vertical-to-surface transmission electrophotonic devices.

Applied optics

Yamanaka Y, Yoshihara K, Ogura I, Numai T, Kasahara K, Ono Y.
PMID: 20725477
Appl Opt. 1992 Aug 10;31(23):4676-81. doi: 10.1364/AO.31.004676.

A free-space optical bus, which consists of cascaded optical switch devices, is proposed. The switch devices have multiple functions, such as data transmission, data detection, and data repetition. Basic interconnection characteristics were measured with vertical-to-surface transmission electrophotonic devices. Optical...

A 41-year-old woman had a general health examination and was diagnosed with a non-functioning adrenocortical carcinoma (ACC). Despite surgery and chemotherapy with mitotane, the ACC progressed with metastases to the lymph nodes, liver and lung. Initially, she developed adrenal...

Triple helicate constructed by covalent bondings: crystal structure and effective synthesis based on propeller-like substructures.

Organic letters

The title salt, C(16)H(18)N(6)O(2) (2+)·2ClO(4) (-)·2H(2)O, was obtained unintentionally as a major product in the reaction of Zn(ClO(4))(2)·6H(2)O with the N',N'(2)-bis-[(1E)-1-(2-pyrid-yl)ethyl-idene]ethanedihydrazide (H(2)L) ligand. The (H(4)L)(2+) cation lies across a centre of inversion. The pyridiniumimine fragments of (H(4)L)(2+) adopt syn...
