New Synthesis of 2-Substituted Imidazo[2, 1-b]thiazoles and their Antimicrobial Activities
Mahfouz, A.Abdel Aziz,Elhabashy, F.M. The Pharmaceutical Society of Korea 1990 Archives of Pharmacal Research Vol.13 No.1
4, 5-Diphenyl-2-mercaptiomidazole (I) was reacted with hydraziodyl halides IIa-d togive the S-alkyl derivatives III-a-d. Cyclization of IIIa-d afforded imidazo[2, 1-b]-thiazole derivatives Vla, b and VII. Treatment of 1 with a-chloroethylacetoaccetate (IV) gave ethyl 2(4, 5-diphenyl-2-imidazolinylthio)-3-keto-butyrate (V). Compound V coupled with benzendiazonium chloride to give the corresponding phenylhydrazo compound IIId. On heating V with polyphosphoric acid, cyclization took place and 2-acetyl-5, 6-diphenyl-imidazo [2, 1-b] thiazol-3-one (VIII) was obtained. The compound VIII was condensed with aromatic aldehydes to yield the cinnamoyl derivatives 1Xa, b. The antimicrobial activities of compounds IIIa-d, V, VIa, VII were examined.
Facile and rapid preparation of platinum counter electrodes for dye-sensitized solar cells
Sarker, S.,Seo, H.W.,Bakare, F.O.,Aziz, Md.A.,Kim, D.M. Elsevier Sequoia 2016 Journal of photochemistry and photobiology Chemist Vol. No.
<P>Here, we report on the deposition of platinum nanoparticles (PNPs) on fluorine-doped tin oxide (FTO) substrate by synthesizing PNPs through chemical reduction of potassium tetrachloroplatinate with formic acid, and subsequently depositing the PNPs on FTO substrate at 70 degrees C; and application of the chemically reduced Pt electrodes (CRs) as the counter electrodes (CEs) of dye-sensitized solar cells (DSSCs). The surface morphology and catalytic activity of the prepared CRs were studied along with conventional thermally decomposed Pt electrodes (TDs). Electrochemical study showed that the catalytic performance of the CRs toward the reduction of I-3(-) was comparable to that of TDs. Also, the photovoltaic performance of the DSSCs with CRs were similar to that with TDs. The method of preparing Pt electrodes through chemical reduction is so fast that the whole process of preparing a set of CRs, after pre-cleaning of the FTO substrates, takes less than 30 min. Most importantly, the present method enables low temperature fabrication of Pt electrodes even on flexible substrates. (C) 2016 Elsevier B.V. All rights reserved.</P>

<P><B>Abstract</B></P> <P>The Belle II experiment comes with a substantial upgrade of the Belle detector and will operate at the SuperKEKB energy-asymmetric <SUP> e + </SUP> <SUP> e − </SUP> collider with energies tuned to ϒ ( 4 S ) resonance s = 10 . 588 GeV. The accelerator has successfully completed the first phase of commissioning in 2016 and the first electron–positron collisions in Belle II took place in April 2018. Belle II features a newly designed silicon vertex detector based on DEPFET pixel and double-sided strip layers. Currently, a subset of the vertex detector is installed (Phase 2 of the experiment). Installation of the full detector (Phase 3) will be completed by the end of 2018.</P> <P>This paper describes the Phase 2 arrangement of the Belle II silicon vertex detector, with focus on the interconnection of detectors and their integration with the software framework of Belle II. Alignment issues are discussed based on detector simulations and first acquired data.</P>
Highly accurate film thickness measurement based on automatic fringe analysis
Abdelsalam, D.G.,Baek, B.J.,Abdel-Aziz, F.,Chegal, W.,Kim, D. Wissenschaftliche Verlagsgesellschaft m. b. H 2012 OPTIK -STUTTGART- Vol.123 No.16
This paper describes an automated multiple-beam interferometry for measuring a calibrated step height of (27.00+/-3.00) nm nominally. The fringes captured from the multiple-beam Fizeau-Tolansky interferometer were thinned by using a written program to obtain accurate measurement. We claim that multiple-beam interferometry based on automatic fringe thinning process can provide a real time solution for calibrating step heights precisely and with high accuracy. The uncertainty budget of the multiple-beam interferometry method due to incomplete parallelism of the incident beam and the inhomogeneity of the reflecting layers was calculated automatically with a written ray tracing program. The uncertainty budget in multiple-beam interferometry was estimated to be of the order of 3.00nm.

We aimed to investigate any association between hepatitis C virus (HCV) infection and non-Hodgkin's lymphoma (NHL) in the view of cytokines that control inflammation/angiogenesis and their correlation with certain CD markers. NHL patients with or without HCV infection were studied. CD5, CD30, CD3, CD20 and CD45 were immunohistochemically evaluated. Plasma levels of vascular endothelial and platelet derived growth factors (VEGF, and PDGF), tumor necrosis factor (TNF-${\alpha}$), transforming growth factor (TGF-${\beta}$), interleukin-6 (IL-6), IL-8, IL-4, IL-12 and interferon gamma (IFN-${\gamma}$) were detected by enzyme-linked immunosorbent assay (ELISA). HCV+ve NHL patients showed a significant reduction in VEGF, PDGF, IFN-${\gamma}$, CD5 and CD45 and a significant increase in IL-12 and IL-8. In conclusion, there was a significant change in cytokine secretion and expression of CD markers in HCV+ve NHL patients. Based on our results, HCV infection in NHL patients requires more in-depth investigations to explore any role in lymphoma progression.
Feasibility of clay-shielding material for low-energy photons (Gamma/X)
S.M. Tajudin,A.H.A. Sabri,M.Z. Abdul Aziz,S.F. Olukotun,B.M. Ojo,M.K. Fasasi 한국원자력학회 2019 Nuclear Engineering and Technology Vol.51 No.6
While considering the photon attenuation coefficient (m) and its related parameters for photonsshielding, it is necessary to account for its transmitted and reflected photons energy spectra and dosecontribution. Monte Carlo simulation was used to study the efficiency of clay (1.99 g cm 3) as a shieldingmaterial below 150 keV photon. Am-241 gamma source and an X-ray of 150 kVp were calculated. Thecalculated value of m for Am-241 is higher within 5.61% compared to theoretical value for a single-energyphoton. The calculated half-value layer (HVL) is 0.9335 cm, which is lower than that of ordinary concretefor X-ray of 150 kVp. A thickness of 2 cm clay was adequate to attenuate 90% and 85% of the incidentphotons from Am-241 and X-ray of 150 kVp, respectively. The same thickness of 2 cm could shield thegamma source dose rate of Am-241 (1 MBq) down to 0.0528 mSv/hr. For X-ray of 150 kVp, photons below60 keV were significantly decreased with 2 cm clay and a dose rate reduction by ~80%. The contributionof reflected photons and dose from the clay is negligible for both sources.
