Structural Porosity and Low Mineral Density in Enamel Rods Drive Molar Incisor Hypomineralisation
Advanced Functional Materials, EarlyView.This study uses advanced imaging modalities on multiple length scales to show that molar‐incisor hypomineralization does not present as a locally homogeneous pathology. Instead, microstructural defects, characterized through non‐mineralized, protein‐rich sheaths and an altered mineral structure in between prism rods, resulting in local differences in ...

The 14C(n,g) cross section between 10 keV and 1 MeV [PDF]
, 2008 The neutron capture cross section of 14C is of relevance for several nucleosynthesis scenarios such as inhomogeneous Big Bang models, neutron induced CNO cycles, and neutrino driven wind models for the r process.

Advanced Functional Materials, EarlyView.Materials exist that are useful for gamma scintillation, radiation shielding, neutron‐gamma pulse shape discrimination (PSD), thermal neutron detection, or high refractive index applications. While certain materials have exhibited optimal performance for each of these applications, none achieve multiple functions.

Atmospheric pollution assessment with mosses in Western Rhodopes, Bulgaria [PDF]
Journal of BioScience and Biotechnology, 2016 The moss analysis technique was applied to monitor 10 heavy metals and toxic elements deposition. Our study was the first attempt to assess spatial patterns in a border mountain region (area 8732 km2) with a low population density and high proportion of ...

Bio‐Inspired Molecular Events in Poly(Ionic Liquids)
Advanced Functional Materials, EarlyView.Originating from dipolar and polar inter‐ and intra‐chain interactions of the building blocks, the topologies and morphologies of poly(ionic liquids) (PIL) govern their nano‐ and micro‐processibility. Modulating the interactions of cation‐anion pairs with aliphatic dipolar components enables the tunability of properties, facilitated by “bottom‐up ...

Wear studies made of slip rings and gas bearing components [PDF]
, 1967 Neutron activation analysis techniques were employed for the study of the wear and performance characteristics of slip ring and rotor assemblies and of the problems arising from environmental conditions with special reference to surface contamination ...
