Self-referencing biosensors using Fano resonance in periodic aluminium nanostructures.

Nanoscale 2021 Sep 15. Epub 2021 Sep 15.

Research Center for Applied Sciences, Academia Sinica, Taipei 11529, Taiwan.

Surface plasmon resonance (SPR) is an important technique for real-time and label-free detection of specific binding biomolecules. However, conventional SPR signals come from both the surface binding biomolecules and the variation in the bulk refractive index. This work demonstrates that Fano resonance in an aluminum capped nanoslit array has the ability to remove the signal of bulk refractive index changes from the SPR signal. Read More

Abiotic reduction of nitrite by Fe(II): a comparison of rates and NO production.

Environ Sci Process Impacts 2021 Sep 13. Epub 2021 Sep 13.

Department of Civil and Environmental Engineering, University of Iowa, Iowa City, Iowa 52242, USA.

Abiotic reduction of nitrite (NO) by Fe(II) species (, chemodenitrification) has been demonstrated in a variety of natural environments and laboratory studies, and is a potentially significant source of atmospheric nitrous oxide (NO) emissions. It is, however, unclear how chemodenitrification rates and NO yields vary among heterogeneous Fe(II) species under similar conditions and whether abiotic reduction competes with biological NO reduction.

The association between female reproductive performance and leukocyte telomere length in wild Soay sheep.

Mol Ecol 2021 Sep 12. Epub 2021 Sep 12.

Institute of Evolutionary Biology, School of Biological Sciences, University of Edinburgh, Edinburgh, EH9 3FL, UK.

Telomere length (TL), typically measured across a sample of blood cells, has emerged as an exciting potential marker of physiological state and of the costs of investment in growth and reproduction within evolutionary ecology. While there is mounting evidence from studies of wild vertebrates that short TL predicts raised subsequent mortality risk, the relationship between reproductive investment and TL is less clear cut, and previous studies report both negative and positive associations. In this study, we examined the relationship between TL and different aspects of maternal reproductive performance in a free-living population of Soay sheep. Read More

Parameter Identification from Normal and Pathological Middle Ears Using a Tailored Parameter Identification Algorithm.

J Biomech Eng 2021 Sep 10. Epub 2021 Sep 10.

Reutlingen University, 72762 Reutlingen, Germany.

Current clinical practice is often unable to identify the causes of conductive hearing loss in the middle ear with sufficient certainty without exploratory surgery. Besides the large uncertainties due to interindividual variances, only partially understood cause-effect principles are a major reason for the hesitant use of objective methods such as wideband tympanometry in diagnosis, despite their high sensitivity to pathological changes. For a better understanding of objective metrics of the middle ear, this study presents a model that can be used to reproduce characteristic changes in metrics of the middle ear by altering local physical model parameters linked to the anatomical causes of a pathology.

Temperature Dependence of Sorption.

Langmuir 2021 Sep 9. Epub 2021 Sep 9.

Division of Chemical Engineering, Graduate School of Engineering Science, Osaka University, Toyonaka, Osaka 560-8531, Japan.

Understanding how sorption depends on temperature on a molecular basis has been made difficult by the coexistence of isotherm models, each assuming a different sorption mechanism and the routine application of planar, multilayer sorption models (such as Brunauer-Emmett-Teller (BET) and Guggenheim-Anderson-de Boer (GAB)) beyond their premises. Furthermore, a common observation that adsorption isotherms measured at different temperatures fall onto a single "characteristic curve" when plotted against the adsorption potential has not been given a clear explanation, due to its ambiguous foundation. Extending our recent statistical thermodynamic fluctuation theory of sorption, we have generalized the classical isosteric theory of sorption into a statistical thermodynamic fluctuation theory and clarified how sorption depends on temperature.
