Conformational and thermal characterization of a synthetic peptidic fragment inspired from human tropoelastin: Signature of the amyloid fibers [PDF]

open access: yes, 2014
Objectives : This work deals with the conformational and thermal characterization of a synthetic peptide (S4) released during the proteolysis of human tropoelastin by the matrix metalloproteinase-12 that was shown to form amyloid-like fibres under ...

Ideal Molecular Sieving with a Dense MOF for Helium Upgrading with Highly Diffusion Selective Mixed Matrix Membranes

open access: yesAdvanced Functional Materials, EarlyView.
The separation of Helium gas from natural gas is challenging but highly important. MIL‐116(Ga), a “non‐porous” metal–organic framework is used as a molecular sieve to separate He from CH4. Druse‐like MIL‐116(Ga) particles are integrated into polysulfone mixed matrix membranes.

Structural and morphological studies of polypropylene/kaolin nanocomposite [PDF]

open access: yes, 2018
Nanocomposite of polypropylene (PP) was made by melt intercalation technique with nanokaolin. Kaolin particles were modified with urea by intercalation to produce nanokaolin. Structural and morphological analyses of polypropylene/kaolin nanocomposite was

Highly Efficient 3D‐Printed PVDF‐Based Triboelectric Nanogenerators Featuring Polymorphic Perovskite Nanofillers

open access: yesAdvanced Functional Materials, EarlyView.
This study demonstrates the use of a low‐cost 3D printing technique to prepare a large‐area PVDF‐FAPbI3 composite dielectric film for flexible TENG application. The δ→α phase transformation of the FAPbI3 nanofillers has significantly improved the β‐phase content, morphology, and dielectric properties of the PVDF film.

FT‐IR spectroscopy for the detection of liver damage [PDF]

open access: yesJournal of Spectroscopy, 2004
A spectroscopic analysis of hepatotoxic effects on rat liver, caused by a single administration of carbon tetrachloride (CCl4), has been performed by Fourier Transform Infrared (FT‐IR) absorption technique in a wide range of frequency 3000–400 cm–1. The spectral investigation has permitted us to mark the dynamical changes of rat liver samples vs.

Hyperbranched Interpenetrating Hydrogen Bond Network (HIHBN) Proton Exchange Membrane for Fuel Cells Above 220 °C

open access: yesAdvanced Functional Materials, EarlyView.
A novel polymer electrolyte membrane with a hyperbranched interpenetrating hydrogen bond network structure is developed. The unique structure of the hyperbranched polymer contributes to a high glass transition temperature exceeding 400 °C, enabling its operation at elevated temperatures for fuel cell applications.
