    Publikationsdatum: 2013-08-30
    Beschreibung: Author(s): I. Razdolski, D. G. Gheorghe, E. Melander, B. Hjörvarsson, P. Patoka, A. V. Kimel, A. Kirilyuk, E. Th. Papaioannou, and Th. Rasing Surface plasma resonance (SPR) excitation in a Co-based two-dimensional magnetoplasmonic crystal was found to strongly enhance the second-harmonic generation (SHG) efficiency. Large changes in the phase shift between magnetic and nonmagnetic SHG contributions were observed in the transversal Kerr ef... [Phys. Rev. B 88, 075436] Published Thu Aug 29, 2013

    Zone electrophoretic sample treatment coupled on-line with column liquid chromatography for the determination of basic and acidic compounds in biological samples (1992)

    Notizen: Summary A modified valve arrangement for zone-electrophoretic sample treatment (ZEST)-which is coupled on-line with column liquid chromatography — is used to pretreat biological (plasma) samples. Carry-over of plasma proteins depends on the pH of the electrophoresis buffer. The determination of propranolol, metoprolol, cromolyn and salicylic acid demonstrates that both basic and acidic analytes can be isolated from the plasma matrix with high selectivity. Analogous piperazines, with different protein binding properties, were used to study the influence of protein binding on the recovery. It is shown that high protein can cause a decreased recovery.

    A new valve for zone-electrophoretic sample treatment coupled on-line with high performance liquid chromatography (1990)
    Springer
    Chromatographia 29 (1990), S. 217-222 
    Details
    ISSN: 1612-1112
    Schlagwort(e): Column liquid chromatography ; Sample treatment ; Zone electrophoresis
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Chemie und Pharmazie
    Notizen: Summary The design of a new valve arrangement for zone-electrophoretic sample treatment (ZEST) coupled online with high performance liquid chromatography is described. Characteristics of this valve, such as the internal heat development as a function of the current, have been investigated. By using quinidine and desipramine as model compounds it is shown that charged compounds can be isolated from biological samples, in about 15 min, with high selectivity. The carry-over of proteins to the analytical column has been compared with the carry-over using a pre-column sample clean-up method. The detection limits of quinidine and hydroquinidine (50 ng/ml), using zone-electrophoretic sample treatment coupled with column liquid chromatography, are in the same range as with direct injections using pre-columns.

    Electrodialytic sample treatment coupled on-line with high-performance liquid chromatography (1990)
    Springer
    Chromatographia 30 (1990), S. 361-366 
    Details
    ISSN: 1612-1112
    Schlagwort(e): Column liquid chromatography ; Electrodialytic sample treatment ; On-line coupling
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Chemie und Pharmazie
    Notizen: Summary An electrodialytic sample treatment method coupled on-line with high-performance liquid chromatography (EDIST-HPLC) is discussed in this paper. The performance of EDIST as a function of the donor-phase (sample solution) flow rate, the voltage applied over the electrodialysis block, and the time of dialysis has been studied using the basic drug ephedrine as a model compound. Enrichment of the analyte by a factor of 10–20 was possible. The determination of human plasma spiked with ephedrine is briefly discussed.

    Theoretical models for electrodialytic sample treatment in trace analysis by liquid chromatography (1994)
    Springer
    Chromatographia 39 (1994), S. 460-468 
    Details
    ISSN: 1612-1112
    Schlagwort(e): Column liquid chromatography ; Electrodialytic sample treatment ; Computer models ; Analyte enrichment
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Chemie und Pharmazie
    Notizen: Summary Basic considerations for analyte enrichment and recovery obtainable by electrodialysis as a sample treatment method are given. Equations are derived which describe the dependence of the concentration profiles of ionic compounds on the electric field strength in a set-up with stagnant donor and acceptor solutions. It is shown that analyte recovery increases when less ion-selective membranes are used in the electrodialysis cell. Computer models are used to estimate the analyte enrichment for a flowing donor (sample) and a stagnant acceptor phase. About 10-fold enrichment can be obtained in an electrodialytic sample treatment system within 20 min under maximum current conditions. A compromise has to be found between analyte recovery and the donor (sample) flow rate.

    Vijfde aanvulling op de naamlijst van Nederlandse sluipvliegen (Diptera: Tachinidae) (2016)

    Beschreibung: De familie der sluipvliegen is één van de soortenrijkste vliegenfamilies in ons land. De larven ontwikkelen zich inwendig in ongewervelden, veelal vlinderrupsen. De groep is in ons land relatief goed bestudeerd en de afgelopen jaren zijn diverse aanvullingen op de checklist uit 2002 gepubliceerd. In dit artikel worden wederom twee soorten voor het eerst uit ons land vermeld. Hiermee komt het totaal aantal soorten dat in Nederland is vastgesteld op 336. Daarnaast wordt de herontdekking van een soort beschreven die al meer dan een eeuw niet meer waargenomen was.

    Beschreibung: Faunistic review of the Dutch woodlouse-flies (Diptera: Rhinophoridae) The faunistics of the seven Dutch species of Rhinophoridae are discussed. Of each species a short diagnosis , its distribution in the Netherlands, habitat and phenology are given. The larvae of all Rhinophoridae are endoparasites on woodlice (Isopoda: Oniscidae). In a separate paper information on associations with hosts and other ecological information will be discussed.

    Diplocoelus fagi nieuw voor de fauna van Nederland (Coleoptera: Biphyllidae) (2015)

    Beschreibung: In 2007 werd Diplocoelus fagi bij Wageningen gevonden. De larven van deze kever leven in dood hout. Na de eerste vondst zijn diverse andere waarnemingen gedaan en D. fagi is nu bekend uit vier provincies. Omdat de soort in de omringende landen al lang bekend was, is deze late ontdekking opmerkelijk. Mogelijk hangt dit samen met het verbeterde bosbeheer, waarbij minder dood hout uit de bossen wordt verwijderd.
