Using Polymerization-Induced Self-Assembly in Orthogonally-Reactive Dispersants to Design Tough Nanostructured Materials: Application to Epoxy Networks. [PDF]

Angew Chem Int Ed Engl
Polymerization‐induced self‐assembly (PISA) can be efficiently performed in orthogonally reactive dispersants such as epoxides (DGEBA or ECC) to generate a range of reactive block copolymer dispersions displaying different morphologies. Subsequent polymerization of the epoxide dispersant (through epoxy‐amine reaction or cationic photopolymerization ...

An arbuscular mycorrhiza from the 407-million-year-old Windyfield Chert identified through advanced fluorescence and Raman imaging. [PDF]

New Phytol
Summary Mycorrhizal associations between fungi and plants are a fundamental aspect of terrestrial ecosystems. Mycorrhizas occur in c. 85% of extant plants, yet their geological record remains sparse. Rare fossil evidence from early terrestrial environments offers crucial insights into these ancient symbioses, but visualizing fossil fungi at the ...

Correlated X-Ray and Electron Microscopies of a Single Biphasic GaAs Nanowire. [PDF]

Small Methods
Nano‐focused scanning X‐ray diffraction microscopy at a synchrotron light source, combined with transmission electron microscopy, reveals a clear correlation between the nanoscale distribution of cubic and hexagonal segments in a GaAs nanowire with subtle variations in inter‐reticular spacing, bending, and twisting.

Phenotypical and Genomic Characterization of the Mollusk Pathogen Francisella halioticida. [PDF]

Microbiologyopen
Phenotypic and genetic characterization of French isolates of Francisella halioticida and comparison with Canadian and Japanese strains. The study revealed similarities between FR22s and previous isolates but distinct differences with FR21. A major finding is the absence of the Francisella pathogenicity island in the less virulent isolate, FR22b ...

Characterizing precipitation defects in nickel based 718 alloy [PDF]

, 2010
In the present study we examine the crystallographic structure of the ϒ, ϒ'' and δ phases present in nickel base 718 alloy. The chemical ordering of Nb atoms and possible planar faults that may be observed in ϒ'' precipitates are detailed.

Validity of the Cauchy-Born rule applied to discrete cellular-scale models of biological tissues. [PDF]

, 2013
The development of new models of biological tissues that consider cells in a discrete manner is becoming increasingly popular as an alternative to continuum methods based on partial differential equations, although formal relationships between the ...

Morphological and Morphometric Analysis of Animal Hair From 18th Century Burial Sites in Mazamet (Southwest France)

Archaeometry, EarlyView.
ABSTRACT Morphological and morphometric analysis of archaeological animal hairs offers a nondestructive method to explore past clothing. We examined hair from two 18th‐century burial areas (SP03 and SP04) in Mazamet, France. SP03 specimens exhibited a continuous medulla, a low medullary index (0.2 ± 0.03) and cuticular features suggesting goat or ...

Streaming potential analysis of hair variation: Ethnicities and environmental exposures

International Journal of Cosmetic Science, EarlyView.
Ethnicity and weathering shape electrokinetic behaviour and particle deposition in hair. ζ‐potential magnitudes ranked Caucasian > Indian > Chinese with no significant root‐tip variations. Deposition patterns generally correlate with ζ‐potential but differ by ethnicity, implicating other factors.

Effect of the over-ageing treatment on the mechanical properties of AA2024 aluminum alloy. [PDF]

, 2012
The evolution of the hardness of the over-ageing AA2024 alloy scale was followed by measurements of Vickers hardness. The nanoindentation is adapted to the determination of elastoplastic properties (hardness and Young’s modulus) of the matrix and also of

Investigation into the delivery and evaluation of a unique Avena sativa (Oat) Lipid Extract on skin barrier using LC‒MS/MS, Raman spectroscopy, immunostaining analysis and skin efficacy

International Journal of Cosmetic Science, EarlyView.
Abstract Objectives Oat lipids are rich in ceramides. In this investigation, we analysed the delivery of a specific Oat Lipid Extract derived from Avena sativa, comprising ‘skin identical’ ratios of fatty acids, ceramides and cholesterol/sterol. This investigation is the first reported investigation of oat lipids utilizing Raman spectroscopy for the ...
