Published: December 2014

ObjectivesIn 1828, between 8,000 and 15,000 Indians from the Jesuit Missions were brought to Uruguay. There, they were settled in a village, presently named Bella Unión, in the northwest corner of the country. According to historic sources, the Indians abandoned the settlement shortly thereafter, with the village subsequently repopulated by “criollos” and immigrants from abroad. As a first approach to reconstruct the genetic history of the population, data about the living population genetic structure will be used. Based on the analysis of the maternal lineages of the inhabitants of Bella Unión, and of those from two nearby villages, we expect to partially answer what happened with the first and subsequent inhabitants.MethodsWe analyzed the maternal lineages of the present inhabitants of Bella Unión and neighboring localities through the sequencing of the mitochondrial DNA control region.ResultsA total of 64.3%, 5.7%, and 30% of the mtDNAs were of Native, African, and West Eurasian origin, respectively. These figures are quite similar to that of the population of Tacuarembó, which is located in northeastern Uruguay. The four main Native American founding haplogroups were detected, with B2 being the most frequent, while some rare subhaplogroups (B2h, C1b2, D1f1) were also found. When compared with other Native American sequences, near‐ matches most consistently pointed to an Amazonian Indian origin which, when considered with historical evidence, suggested a probable Guaraní‐Missionary‐related origin.ConclusionsThe data support the existence of a relationship between the historic and present inhabitants of the extreme northwest Uruguay, with a strong contribution of Native Americans to the mitochondrial DNA diversity observed there.

Poröse und formanisotrope Einkristalle des Halbleiter‐Perowskits CH3NH3PbI3 aus einer neuen Single‐Source‐Vorstufe

Published: December 2014

AbstractSignifikante Fortschritte in der Solarzellforschung werden aktuell von der Substanzklasse der metallorganischen Perowskite (MOPs) dominiert. Ursächlich dafür sind herausragende Eigenschaften dieser Materialien, wie hohe Absorptionskoeffzienten und die Fähigkeit zur effektiven Trennung photogenerierter Ladungsträger. In Analogie zu etablierteren Halbleitern kann erwartet werden, dass die Materialeigenschaften auch der MOPs durch eine definierte Nanostrukturierung stark verbessert werden können. Ihre chemische Anfälligkeit (z. B. gegen Hydrolyse) erschwert aber die direkte Übertragung gängiger Verfahren zur Herstellung von Nanomaterialien. Wir berichten über einen originären Ansatz zur Synthese verschiedener (CH3NH3)PbI3‐Nanostrukturen unter Verwendung einer neuartigen Single‐Source‐Vorstufe. Nanoporöse MOP‐Einkristalle können durch eine Kristall‐Kristall‐Umwandlung erhalten werden, die mit einer spinodalen Mikrophasenseparation der Triethylenglykol‐haltigen Vorstufenverbindung einhergeht. Die Steuerung der Nanopartikelform gelingt durch Einsatz eines selektiv bindenden Kristallisationsinhibitors.
Highly soluble and thermally stable copolyimides modified with trifluoromethyl and siloxane

Published: December 2014

ABSTRACTA series of highly soluble aromatic polyimides with excellent thermal properties were fabricated by traditional two‐step polycondensation reaction of dianhydride monomer 4,4′‐(4,4′‐isopropylidenediphenoxy)bis(phthalic anhydride) or 4,4‐(hexafluoroisopropylidene)diphthalic anhydride with diamine monomer 1,3‐bis(4‐aminophenoxy)benzene or 1,3‐bis(3‐aminopropyl) tetramethyldisiloxane in N,N‐dimethylacetylamide solvent. Results revealed that copolyimide of PI‐4 containing trifluoromethyl and tetramethyldisiloxane possessed excellent solubility and remarkable thermal properties. PI‐4 could dissolve well in common low boiling point solvents such as THF of up to 80 mg/mL and acetone of 40 mg/mL. Moreover, the 10% weight loss temperature of the PI‐4 was 539°C and the Tg value of the PI‐4 was 311°C. PI‐4 might be easily cast into flexible and tough films applied in optoelectronic devices. © 2014 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2015, 132, 41713.
Preparation of bi‐modified amphoteric oligochitosan derivatives and electrochemical evaluation on anticorrosion performances
Authors: Zhang Huixin , Wang Dongdong , Jin Xiuhong , Yang Tingru , Shen Xiaoli 
Published: December 2014

ABSTRACTFour bi‐modified amphoteric oligochitosan derivatives were synthesized chemically using quaternization, sulfonation, and carboxylation. The anticorrosion characteristics and mechanism of anticorrosion of these four oligochitosan derivatives on Q235 steel in 1.0 mol/L HCl solution were studied by potentiodynamic polarization and electrochemical impedance spectroscopy at constant temperature. The results suggest that these derivatives are hybrid corrosion inhibitors in which anodic inhibition predominates following the mechanism of adsorption film formation on the surface of the metal. They all have their own optimal dosages for anticorrosion application. Their inhibiting efficiencies are closely related to the nature and the amount of heteroatoms in their molecules. © 2014 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2015, 132, 41714.
A chromosome separation checkpoint
Authors: Maiato Helder , Afonso Olga , Matos Irina 
Published: December 2014

AbstractHere we discuss a “chromosome separation checkpoint” that might regulate the anaphase‐telophase transition. The concept of cell cycle checkpoints was originally proposed to account for extrinsic control mechanisms that ensure the order of cell cycle events. Several checkpoints have been shown to regulate major cell cycle transitions, namely at G1‐S and G2‐M. At the onset of mitosis, the prophase‐prometaphase transition is controlled by several potential checkpoints, including the antephase checkpoint, while the spindle assembly checkpoint guards the metaphase‐anaphase transition. Our hypothesis is based on the recently uncovered feedback control mechanism that delays chromosome decondensation and nuclear envelope reassembly until effective separation of sister chromatids during anaphase is achieved. A central player in this potential checkpoint is the establishment of a constitutive, midzone‐based Aurora B phosphorylation gradient that monitors the position of chromosomes along the spindle axis. We propose that this surveillance mechanism represents an additional step towards ensuring mitotic fidelity.
Die Invasion der Stechmücken
Authors: Becker Norbert , Jöst Artur , Storch Volker 
Published: December 2014

AbstractDie Wissenschaftler der “Kommunalen Aktionsgemeinschaft zur Bekämpfung der Stechmücken” (KABS) und der Universität Heidelberg haben von 1995 bis 2011 vier neue Stechmückenarten als Neozoen für Deutschland nachweisen können. Aedes albopictus und Ochlerotatus j. japonicus sind im Rahmen der Globalisierung mit Handelsgütern bzw. als blinde Passagiere in Kraftfahrzeugen nach Deutschland eingeschleppt worden. Insbesondere die Ausbreitung von Ae. albopictus wird durch die Klimaerwärmung begünstigt. Die rapide Ausbreitung von Ae. albopictus und Oc. j. japonicus sowie die damit verbundenen Risiken der Übertragung von Krankheitserregern, insbesondere von Arboviren auf den Menschen, haben dazu geführt, dass die Culicidenforschung erneut im Fokus der Wissenschaft steht.

Thermodynamic Properties of CO2 Conversion by Sodium Borohydride
Authors: Zhao Yi , Zhang Zili 
Published: December 2014

AbstractIn order to verify the resource utilization of CO2 from coal‐fired flue gas, the conversion of CO2 by sodium borohydride was investigated under atmospheric pressure and moderate temperature. According to the product analysis results of mass spectrometry and ion chromatography, combined with the comparison of electrode potentials, the mechanism of CO2 reaction with sodium borohydride was deduced, in which formate was confirmed as the main reduction product, and the intermediates of [BHi(HCO2)(OH)3–i]−1 were considered as the essential mediums for the formation of formate. The feasibility of this conversion was studied thermodynamically.
