Soft ferromagnetic Fe-based bulk metallic glass key-shaped specimens with a maximum and minimum width of 25.4 and 5 mm, respectively, were successfully produced using a high pressure die casting (HPDC) method, The influence of die material, alloy temperature and...

Evidence of excited state absorption in PS II membrane fragments.

Photosynthesis research

Bittner T, Voigt J, Kehrberg G, Eckert HJ, Renger G.
PMID: 24414972
Photosynth Res. 1991 Jun;28(3):131-9. doi: 10.1007/BF00054126.

Utilizing a two-beam technique in the frequency domain, the pumped absorption of PS II membrane fragments from spinach and of acetonic chlorophyll-a solutions was measured at room temperature. In a very narrow wavelength region (0.2 nm around the pump...

Products of lipid, protein and RNA oxidation as signals and regulators of gene expression in plants.

Frontiers in plant science

Chmielowska-Bąk J, Izbiańska K, Deckert J.
PMID: 26082792
Front Plant Sci. 2015 Jun 02;6:405. doi: 10.3389/fpls.2015.00405. eCollection 2015.

Reactive oxygen species (ROS) are engaged in several processes essential for normal cell functioning, such as differentiation, anti-microbial defense, stimulus sensing and signaling. Interestingly, recent studies imply that cellular signal transduction and gene regulation are mediated not only directly...

AEKF-SLAM: A New Algorithm for Robotic Underwater Navigation.

Sensors (Basel, Switzerland)

Yuan X, Martínez-Ortega JF, Fernández JAS, Eckert M.
PMID: 28531135
Sensors (Basel). 2017 May 21;17(5). doi: 10.3390/s17051174.

In this work, we focus on key topics related to underwater Simultaneous Localization and Mapping (SLAM) applications. Moreover, a detailed review of major studies in the literature and our proposed solutions for addressing the problem are presented. The main...

INBREEDING DEPRESSION IN PARTIALLY SELF-FERTILIZING DECODON VERTICILLATUS (LYTHRACEAE): POPULATION-GENETIC AND EXPERIMENTAL ANALYSES.

Evolution; international journal of organic evolution

Eckert CG, Barrett SCH.
PMID: 28564454
Evolution. 1994 Aug;48(4):952-964. doi: 10.1111/j.1558-5646.1994.tb05285.x.

Inbreeding depression is a major selective force favoring outcrossing in flowering plants. Some self-fertilization, however, should weaken the harmful effects of inbreeding by exposing genetic load to selection. This study examines the maintenance of inbreeding depression in partially self-fertilizing...

Inorganic chemistry

Mikhailova D, Karakulina OM, Batuk D, Hadermann J, Abakumov AM, Herklotz M, Tsirlin AA, Oswald S, Giebeler L, Schmidt M, Eckert J, Knapp M, Ehrenberg H.
PMID: 27367435
Inorg Chem. 2016 Jul 18;55(14):7079-89. doi: 10.1021/acs.inorgchem.6b01008. Epub 2016 Jul 01.

Layered Li(M,Li)O2 (where M is a transition metal) ordered rock-salt-type structures are used in advanced metal-ion batteries as one of the best hosts for the reversible intercalation of Li ions. Besides the conventional redox reaction involving oxidation/reduction of the...

Influence of the Ag concentration on the medium-range order in a CuZrAlAg bulk metallic glass.

Scientific reports

Gammer C, Escher B, Ebner C, Minor AM, Karnthaler HP, Eckert J, Pauly S, Rentenberger C.
PMID: 28322304
Sci Rep. 2017 Mar 21;7:44903. doi: 10.1038/srep44903.

Fluctuation electron microscopy of bulk metallic glasses of CuZrAl(Ag) demonstrates that medium-range order is sensitive to minor compositional changes. By analyzing nanodiffraction patterns medium-range order is detected with crystal-like motifs based on the B2 CuZr structure and its distorted...
