    Description: A study was conducted to analyze the influence of chloride substitution in the fast ion conductor Ag3SBr. Results indicated the presence of free AgS2 that promotes an electronic contribution to conductivity above room temperature. Findings also showed that the overall magnitude of ionic conductivity does not change appreciably as a function of composition near the superionic-covalent phase transition temperature.

    Description: Byline: H.S. Saeed, R.B. Wright, S.K. Ghosh Keywords: allergy 〈 rhinology; complications 〈 rhinology; rhinitis 〈 rhinology; rhino-sinusitis; specialties Objectives Our aim is to present data depicting geographical prescribing trends and expenditure related to topical nasal agent prescriptions across clinical commissioning groups (CCG's) in England. We assess if prescribing trends can act as a surrogate marker for allergic rhinitis (AR) and rhinosinusitis disease burden (RS). Design NHS England primary care prescriptions dispensed for topical drugs used in nasal allergy (BNF chapter 12.2.1) were accessed using OpenPrescribing beta software. Graphical data over a 5-year period was generated to highlight nationwide trends in prescribing and expenditure. Out of 211 CCG districts, the highest and lowest 40 prescribing rate CCG's were subdivided according to rural/urban output and geographical location to highlight specific regional trends. Two sampled, paired and unpaired t tests of unequal variance were performed to determine the significance of observed trends. Results The 5-year trend in prescription rate (mean yearly expenditure A[pounds sterling]40 725 258) for drugs used in nasal allergy marginally increased. Peak prescription was during months of high environmental pollen. Regardless of pollen season (June 2016 vs November 2015), CCG's of urban districts had significantly lower rates of prescribing (P [less than or equal to] .001). Amongst the 40 lowest and 40 highest prescribing rate CCG's, prescription rates fell significantly between months of high and low environmental pollen (P [less than or equal to] .0001). Regardless of pollen season, rural eastern and eastern coastal districts of England had persistently high rates of prescription. Conclusions This study shows marked geographical variation in prescribing for topical nasal agents in England. There is propensity for eastern districts to have higher rates of prescribing in England. Adopting prescribing trends as a surrogate marker for disease burden could allow allergy and endoscopic sinus surgery services to be concentrated to specific regions. This would provide more effective, economical treatment for both AR and RS.

    Description: Zr--Ni intermetallic compounds, Zr sub 2 Ni, ZrNi, ZrNi sub 3 , Zr sub 2 Ni sub 7 and ZrNi sub 5 have been investigated by X-ray photoelectron spectroscopy (XPS) for their response to oxidation and reduction. Chemical and structural changes were found to be composition dependent. Results indicate that preferential reaction, segregation and oxide ordering of one metal component or the other under specific treatment conditions explain the observed catalytic activity of these materials for ethylene hydrogenation. 54 ref.--AA

    Description: This paper presents the test results and analysis of the power and capacity fade resulting from the cycle-life testing using PNGV (now referred to as FreedomCAR) test protocols at 25 and 45 degrees C of 18650-size Li-ion batteries developed by the US Department of Energy sponsored advanced technology development (ATD) program. Two cell chemistries were studied, a Baseline chemistry that had a cathode composition of LiNi0.8Co0.15Al0.05O2 with binders, that was cycle-life tested at 25 and 45 degrees C, and a Variant C chemistry with a cathode composition of LiNi0.8Co0.10Al0.10O2 with binders, that was tested only at 45 degrees C. The 300 Wh power, and % power fade were determined as a function of test time, i.e. the number of test cycles for up to 44 weeks (369, 600 test cycles) for the Baseline cells, and for 24 weeks (201, 600 test cycles) for the Variant C cells. The C/1 and C/25 discharge capacity and capacity fade were also determined during the course of these studies. The results of this study indicate that the 300 Wh power for the Baseline cells tested at 25 degrees C (up to 44 weeks of testing) decreased as a linear function of test time. The % power fade for these cells increased as a linear function of test time. The Baseline cells tested at 45 degrees C (up to 44 weeks of testing) displayed a decrease in their power proportional to the square root of the test time, with a faster rate of decrease of the power occurring at approximately 28 weeks of testing. The % power fade for these cells also increased as the square root of the test time, and exhibited an increase in the % power fade rate at approximately 28 weeks of testing. The 45 degrees C tested Baseline cells' power decreased, and their % power fade increased at a greater rate than the 25 degrees C tested Baseline cells. The power fade was greater for the Variant C cells. The power of the Variant C cells (tested at 45 degrees C) decreased as the square root of the test time, and their % power fade was also found to be a function of the square root of the test time (up to 24 weeks of testing), i.e. the rate of decrease in the power and the increase in the % power fade rate was greater for the Variant C cells than for the Baseline cells also tested at 45 degrees C. The C/1 and C/25 Ah capacities of the Baseline cells tested at 25 and 45 degrees C were determined to be a function of the square root of the cycle time (i.e. number of test cycles) for test times up to 44 weeks. The capacity fade was greater at 45 degrees C than at 25 degrees C. Similarly, the C/1 and C/25 charge capacities of the Variant C cells were found to be a function of the square root of the test time (up to 24 weeks of testing). The C/1 and C/25 charge capacities decreased as a function of test time and the rate of decrease was smaller for the Variant C cells as compared to the Baseline cells over comparable test times (24 weeks).

    Description: In sehr ausfuehrlicher mathematischer Weise wird ueber die theoretische Grundlagen eines mit Laserstrahlanregung arbeitenden Fluoreszenz-Spektroskopieverfahrens (LIF) zur Bestimmung der Geschwindigkeitsverteilung von Zirkoniumatomen berichtet, die sich beim Metalltargetbeschuss mit 1 bis 3 keV in der Edelgasumgebung von Kr(+) und Ar(+) einstellt. Die Anregung erfolgt mit einem abstimmbaren, gepumpten Farblaser. Die Bestimmung der Geschwindigkeitsverteilung erfolgt durch Abtastung der Laserfrequenz durch die Doppler-verschobenen Absorptionsfrequenzen der auftretenden Atome mit einem Laserstrahlnormal der Targetoberflaeche. Zur Beschreibung dieser LIF-Prozesse entwickelte man ein Modell mit 3 Atomenergiebereichen (Wechselwirkung eines Laserstrahls mit bekannter Bandbreite, Strahldichte, Pulsdauer und Strahldurchmesser). Ein weiterer wichtiger Modellparameter war die Uebergangsgeschwindigkeit in diesen Atomenergiebereichen (Fluoreszenzerregung, Emissionsbereiche). Von der Targetkammer wird ein Schnittbild gezeigt. Im LIF-Spektroskopieverfahren bei unterschiedlichen Energiedichten des Anregungslaserstrahls erhaltene Geschwindigkeitsverteilungsergebnisse fasste man in zahlreichen Diagrammen zusammen.
