The Strange Death of Ibrahim Khalil Khan of Qarabagh
No full textIbrahim Khalil Khan, the octogenarian ruler of Qarabagh in the southern Caucasus, was shot by Russian soldiers on the night of June 14, 1806. In one sense, there is nothing mysterious about the khan's death. Qarabaghi, Russian, and Iranian sources agree that he was killed for having sided with Iran against Russia's attempt to take control of his khanate and all the lands between the High Caucasus and the Aras River. However, this explanation raises more important questions which have gone unanswered. For years Ibrahim Khalil had sided with Georgia and then Russia against Iran. What made him switch sides in time of war? Russia did not plan to supplant rule by khan in Qarabagh and did not kill every ruler it deposed. Why then did the Russians kill this khan? How was it possible for the execution of Russian policy to slip out of St. Petersburg's control?</jats:p

Get PDFAuthentication, detection and quantification of the ingredients, and adulterant in the food, meat and meat products are of high importance in current days. However, the conventional meat species detection techniques based on lipid, protein and DNA biomarkers have been confronting challenges due to the poor selectivity, sensitivity, and unsuitability for processed food products or complex food matrices. Hence, nanoparticle based DNA biosensing strategies have attracted the most interests and considered as one of the best alternatives to conventional strategies. Among these, surface enhanced Raman scattering (SERS) has gained the substantial acceptance as an excellent, fast and ultrasensitive sensing technique due to its ability to produce molecule specific distinct spectra, narrow spectral bandwidth and multiplexing ability. However, the performance of the SERS DNA biosensor relies on the DNA probe length, platform composition, presence and position of Raman tags and the chosen sensing strategy. Herein, it was demonstrated for the first time SERS DNA sensing for the detection meat species using short-length DNA probe and two different strategies of Raman tag attachment either co adsorbed with or intercalated in the DNA probe sequences. Moreover, SERS-active dual platforms comprising of graphene oxide-gold nanoparticles (GO-AuNPs), graphene oxide-gold nanorod (GO-AuNR), and AuNPs were used in different combinations. At the first sensing strategy, GO-AuNP functionalized with capture probe 1 (CP1) and AuNPs with co-adsorbed CP2 and Cy3 were used to fabricate the SERS biosensor for the quantitative detection of the Malayan Box Turtle (MBT). Hybridization mediated coupling of the two platforms generated the huge amplified SERS signal which in consequence facilitated to achieve a greater sensitivity with a limit of detection (LOD) of 10 fM (synthetic target DNA) and 100 fM (real sample). In the second strategy, a uniquely
designed Raman tag (ATTO Rho6G) integrated signal probe (SP) sequence immobilized AuNPs and the CP DNA functionalized GO-AuNR were utilized to detect the pig species. This biosensing approach showed an outstanding sensitivity with an LOD of 100 aM as well as validated with DNA extracted from pork sample (LOD
– 1fM). Finally, a duplex SERS DNA biosensor was fabricated following the same strategy using Cy3 and ATTO Rho6G intercalated SP sequences specific to MBT and pig species respectively as well as GO-AuNPs and AuNPs as sensor platforms for the simultaneous detection of both species. In the presence of the target DNA sequences, covalent linking of the CP functionalized GO-AuNPs and SP functionalized AuNPs triggered the huge SERS signal enhancement due to the multi-component agglomeration. The duplex DNA biosensor exhibited an excellent sensitivity with an LOD of 10 fM for the synthesized target DNA and 100 fM for real sample. Moreover, the fabricated SERS biosensors showed an outstanding selectivity and specificity to differentiate the DNA sequences of the closely related non-target species and the target DNA sequences with single and three nucleotide base-mismatches. The developed short-length DNA conjugated dual platforms based SERS biosensors proved as a selective, sensitive and convenient technology for the detection of single and dual species, hence could be universally applicable for the versatile applications and opted for the simultaneous multiplex detection

No full textSynthesis and characterization of core-shell electrocatalysts for fuel cells application
Get PDFPolymerelektrolytbrennstoffzellen (PEMFC) sind eine vielversprechende Technologie, um Elektrizität durch die direkte Umwandlung chemischer in elektrische Energie zu erhalten. Das größte Problem für eine PEMFC-Kommerzialisierung stellt immer noch die träge Kinetik der elektrokatalytischen Sauerstoffreduktionsreaktion (ORR) im sauren Elektrolyten dar. In dieser Arbeit wurde eine Reihe von legierten PtCu/CNTs- und Cu@Pt/CNTs-Elektrokatalysatoren durch die Mikrowellen-gestützte Polyol-Methode, mit und ohne Natriumborhydrid (NaBH4), in einem einstufigen oder zweistufigen Herstellungsverfahren hergestellt. Dabei konnte beobachtet werden, dass, abhängig von der Präparationsmethode, die Kern-Schale-Katalysatoren eine bis zu 4,5-fach höhere spezifische und massenbezogene Aktivität im Vergleich zu kommerziellen Pt/C-Katalysatoren aufwiesen.Polymer electrolyte membrane fuel cell (PEMFCs) is a promising technology supplying electricity by converting the energy stored in chemical fuels into electrical energy. Several challenges impede PEMFC commercialization among them the slow kinetics of the oxygen reduction reaction (ORR) even on Pt. Core-shell nanoparticles have emerged as a novel class of catalysts with high activity for ORR. A set of PtCu/CNTs alloys have been prepared by microwave-assisted polyol method, the core-shell structure was obtained by electro/chemical dealloying of the prepared alloys in an acidic solution. Depending on the preparation process/parameters the most active catalysts demonstrated up to 4.5 fold enhancement in the ORR activities when compared to the commercial Pt/C catalyst.vorgelegt von Heba Ali Ibrahim Khalil El Dee
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
