Als Humboldt sein 1804 geschriebenes Tagebuch seiner Reise von Mexico City nach Veracruz 1853 nochmals sichtete, schrieb er an den Rand einer Passage die kritischen Worte “Alte neptunistische Verrücktheiten!” Dieser Text und seine spätere Randbemerkung beweisen nun endgültig, daß Humboldt noch gegen Ende seiner Amerikareise Neptunist war, was von Forschern oft bezweifelt worden war. Seltsamerweise hat Humboldt dieses Manuskript nicht mit in die Tagebücher aufgenommen, als er sie gegen Ende seines Lebens in 9 Hefte neu binden ließ. Der Nachlaß Humboldts galt zusammen mit der Autographensammlung der Staatsbibliothek Berlin seit der Auslagerung im zweiten Weltkrieg als verschollen. Er befindet sich heute in Krakau, wo ich diesen Tagebuchteil vor einiger Zeit entdeckte, das nun eine wertvolle Ergänzung zur Edition der Tagebücher durch Margot Faak bildet. Der folgende Text stellt diesen Tagebuchteil vor und zeigt die Entwicklung einzelner Ansichten Humboldts in naturwissenschaftlichen Disziplinen, die z. T. paradigmatische Wandel von Theorien - beispielsweise in der Geologie - anzeigen.

Am 19. Dezember 1831 wurde der verdienstvolle Mikrobiologe Christian Gottfried Ehrenberg zum korrespondierenden Mitglied des Institut de France gewählt. Alexander von Humboldt, der Ehrenberg als Wissenschaftler hoch schätzte, hat sich energisch für diese Wahl eingesetzt. Ein Zeugnis seines Engagements ist ein Brief an den Mediziner Antoine Baron Portal (1742-1832), den er um seine Stimme bei der bevorstehenden Wahl bat. Die Geschichte der Wahl Ehrenbergs in Verbindung mit diesem Brief und die Gründe für Humboldts Interesse daran sollen hier kurz skizziert werden.

An alternative method for the structure tuning of carbon nitride materials by using a supramolecular approach in combination with caffeine as lining-agent is described. The self-assembly of the precursor complex consisting of melamine and cyanuric acid can be controlled by this doping molecule in terms of morphology, electronic, and photophysical properties. Caffeine is proposed to insert as an edge-molecule eventually leading to hollow tube-like carbon nitride structures with improved efficiency of charge formation. Compared to the bulk carbon nitride, the caffeine-doped analogue possesses a higher photocatalytic activity for the degradation of rhodamineB dye. Furthermore, this approach is also shown to be suitable for the modification of carbon nitride electrodes.

Background: There is an increasing awareness of the impact of parental risk perception on the weight course of the child and the parent's readiness to engage in preventive efforts, but only less is known about factors related to the parental perception of the right time for the implementation of preventive activities. The aim of this study was to examine parental perceptions of the appropriate time to engage in child weight management strategies, and the factors associated with different weight points at which mothers recognize the need for preventive actions. Methods: 352 mothers with children aged 2-10 years took part in the study. We assessed mothers' perceptions of the actual and preferred weight status of their child, their ability to identify overweight and knowledge of its associated health risks, as well as perceptions of the right time for action to prevent overweight in their child. A regression analysis was conducted to examine whether demographic and weight related factors as well as the maternal general risk perception were associated with recognizing the need to implement prevention strategies. Results: Although most of the parents considered a BMI in the 75th to 90th percentile a valid reason to engage in the prevention of overweight, 19% of the mothers were not willing to engage in prevention until their child reached the 97th percentile. Whereas the child's sex and the identification of an elevated BMI were significant predictors for parents' recognition of the 75th percentile as right point to engage in prevention efforts, an inability to recognize physical health risks associated with overweight silhouettes emerged as a significant factor predicting which parents would delay prevention efforts until a child's BMI reached the 97th percentile. Conclusion: Parental misperceptions of overweight and associated health risks constitute unfavorable conditions for preventive actions. Feedback on the health risks associated with overweight could help increase maternal readiness for change.

Driven mostly by the search for chemical syntheses under biocompatible conditions, so called "click" chemistry rapidly became a growing field of research. The resulting simple one-pot reactions are so far only scarcely accompanied by an adequate optimization via comparably straightforward and robust analysis techniques possessing short set-up times. Here, we report on a fast and reliable calibration-free online NMR monitoring approach for technical mixtures. It combines a versatile fluidic system, continuous-flow measurement of H-1 spectra with a time interval of 20 s per spectrum, and a robust, fully automated algorithm to interpret the obtained data. As a proof-of-concept, the thiol-ene coupling between N-boc cysteine methyl ester and ally] alcohol was conducted in a variety of non-deuterated solvents while its time-resolved behaviour was characterized with step tracer experiments. Overlapping signals in online spectra during thiol-ene coupling could be deconvoluted with a spectral model using indirect hard modeling and were subsequently converted to either molar ratios (using a calibration free approach) or absolute concentrations (using 1-point calibration). For various solvents the kinetic constant k for pseudo-first order reaction was estimated to be 3.9 h(-1) at 25 degrees C. The obtained results were compared with direct integration of non-overlapping signals and showed good agreement with the implemented mass balance. (C) 2017 Elsevier Inc. All rights reserved.

La "antiquización" de América – implementar motivos clásicos como modelos de apropriación imperial – es una de las estrategias retóricas más importantes en la relación de viaje de Alexander von Humboldt. Mediante la experiencia colonial, sin embargo, este discurso se deestabiliza: Se ponen en contradicción referencias metafóricas y metonímicas, connotaciones positivas y negativas, diferentes modos de temporalización, identificaciones coloniales y disidentes etc. El concepto de Antigüedad se de-autoriza – está deconstruido. Observamos la disolución del clasicismo europea como dispositivo político-estético en el contacto con la diferencia cultural.
