Abnormal behavior of dopant activation was observed in P + /B + ion shower doped poly-Si upon post implant annealing. Phosphorous or boron was implanted by ion shower doping using a source gas mixture of PH3/H2 or B2H6/H2. Activation annealing was conducted using a tube furnace in the temperature ranges from 350 o C to 650 o C. Hall measurement revealed that reverse annealing occurred for poly-...

Oxidative cleavage of poly(cis-1,4-isoprene) by rubber oxygenase RoxA purified from Xanthomonas sp. was investigated in the presence of different combinations of (16)O(2), (18)O(2), H(2)(16)O, and H(2)(18)O. 12-oxo-4,8-dimethyl-trideca-4,8-diene-1-al (ODTD; m/z 236) was the main cleavage product in the absence of (18)O-compounds. Incorporation of one (18)O atom in ODTD was found if the cleavage...

In this work, Phosphotungstic Acid modified Carbon Paste Electrode (PWA-CPE) is used as a substrate for electro-polymerization of o-Anisidine (OA). Also, Triton X-100 (TX-100) surfactant is used as an additive for electrochemical polymerization of OA onto the PWA-CPE, which is investigated as a novel matrix for dispersion of nickel species. The prepared electrodes are characterized by...

We prove the following results: (i) PV proves NP ⊆ P/poly iff PV proves coNP ⊆ NP/O(1). (ii) If PV proves NP ⊆ P/poly then PV proves that the Polynomial Hierarchy collapses to the Boolean Hierarchy. (iii) S2 proves NP ⊆ P/poly iff S 1 2 proves coNP ⊆ NP/O(log n). (iv) If S2 proves NP ⊆ P/poly then S 1 2 proves that the Polynomial Hierarchy collapses to P[log n]. (v) If S2 proves NP ⊆ P/poly the...

The title compound, [Na(C12H8N2O8P)], consists of one Na(+) cation and one bis-(p-nitro-phen-yl)phosphate anion with a considerable distortion of the phosphate tetra-hedron due to the presence of two P-O ester bonds. The anion bridges five Na(+) cations whereby each cation is chelated by the nitro O atoms of one anion and bonded via a nitro O atom and phosphate O atoms to four other anions. Thi...

Poly(4-vinylpyridine)-supported copper iodide nanoparticles is reported as a new, green and recyclable catalyst for the synthesis of aryl-14H-dibenzo [a-o] xanthenes under solvent-free conditions. This catalyst can be recovered by simple filtration and recycled up to 8 consecutive runs without any loss of their efficiency.

The beneficial health effects of cranberries have been attributed to their (poly)phenol content. Recent studies have investigated the absorption, metabolism and excretion of cranberry (poly)phenols; however, little is known about whether they follow a dose response in vivo at different levels of intake. An acute double-blind randomized controlled trial in 10 healthy men with cranberry juices co...

Poly(2'-O-methyladenylic acid) [poly(Am)] inhibited tumor development and death induced by the Moloney sarcoma virus-leukemia virus complex in newborn mice. The compound was effective at 10 mug per mouse when given at least 1 hr before inoculation of virus, but the greatest inhibition was seen in mice treated at least 4 hr before infection. Poly(2'-O-methyluridylic acid) and poly(vinyladenine) ...
