In this work, a series of Pr3+ doped Bi2WO6 had been successfully prepared by one-step hydrothermal method. The Pr- were characterized XRD, UV–Vis DRS, PL, SEM, TEM, XPS and N2 adsorption–desorption to study their physical–chemical properties. Rhodamine B (RhB) was photodegraded as target organic pollutant investigate the photocatalytic activity as-prepared samples. results show that Pr doping ...

We present an extension of the atomic frequency comb protocol that utilizes Stark effect to perform noise-free, on-demand, control. An experimental realization this was implemented in Pr3+:Y2SiO5 solid-state system, and a recall efficiency 38% for 0.8 ?s storage time achieved. Experiments were performed with both bright pulses as well weak-coherent states, latter achieving signal-to-noise ratio...

Frequency-multiplexed quantum communication usually requires a single-shot identification of the frequency mode single photon . In this paper, we propose scheme that can identify with high-resolution even for spontaneously emitted photons whose generation time is unknown, by combining time-to-space and frequency-to-time mapping. We also demonstrate mapping (100 MHz intervals) to temporal (435 n...

Reactions of [Pd(styrene)(PR3)2], generated from trans-[PdEt2(PR3)2] and styrene, with 2 equiv. of benzyl isocyanate in THF at room-temperature afforded unusual cyclic Pd-tetramers of five-membered rings consisting of organic isocyanate dimers and palladium, [Pd(PR3){-C(O)N(R)C(O)N(R)-}]4 (PR3 = PMe3, ; PR3 = PMe2Ph, ). Additionally, a cyclic trimer, (RNCO)3, (R = benzyl) was produced as a cata...

OBJECTIVE Secreted enzymatically inactive proforms of hematopoietic serine proteases proteinase 3 (PR3), azurocidin, and granzymes A, B, H, K, and M are able to reduce the fraction of granulopoietic progenitors (CFU-GM) in S-phase, whereas human leukocyte elastase (HLE) and cathepsin G lack this ability. The objective of the present study was to map the specific sequence(s) of PR3 and other hem...

ANCA vasculitis encompasses several autoimmune conditions characterised by destruction of small vessels, inflammation of the respiratory tract and glomerulonephritis. Most patients harbour autoantibodies to myeloperoxidase (MPO) or proteinase 3 (PR3). Clinical and experimental data suggest that pathogenesis is driven by ANCA-mediated activation of neutrophils and monocytes. We investigated a po...

AIM To assess the possible relationship between serum alpha-1 antitrypsin (AAT) levels and anti-neutrophil cytoplasmic antibodies (ANCA) in autistic children with severe GI disease and to test the hypothesis that there is an association between low serum AAT levels, the presence of ANCA and inflammatory GI disease seen in some autistic children. SUBJECTS AND METHODS Serum from 40 autistic chi...
