Surfactant (PEG 400) effects on crystallinity of ZnO nanoparticles

, 2016
The surfactant effects on the size and crystallinity of ZnO powders prepared by Solid-state mechanochemical method. The present method is a simple and efficient method for the preparation of nanoparticles with high yield at low cost.

Role of Intrinsic Electron Trapping in Negative Charging of Amorphous Alumina

Advanced Functional Materials, EarlyView.
Intrinsic electron trapping in amorphous Al2O3 is examined using hybrid‐DFT models spanning a wide density range. Both spontaneous and thermally activated trapping are identified, with pronounced spontaneous localization in dense, partly crystallized structures.

Fracture of polypropylene: 2. The effect of the crystallinity

, 1998
The effect of crystallinity on the fracture behaviour of polypropylene was studied under impact conditions. The crystallinity was varied by taking low- and high-isotactic polypropylenes and mixtures thereof.

Liquid Phase Transmission Electron Microscopy: A Window into the Early Stages of Complex Material Formation

Advanced Functional Materials, EarlyView.
Liquid‐phase transmission electron microscopy enables direct observation of nucleation and growth processes in solution. This review is dedicated to the remembrance of Helmut Cölfen and highlights recent studies on complex materials—oxides, biominerals, organic–inorganic crystals—which were central to his research activity. It summarizes key milestones,

Research of Oxidation Starch Conversion and Crystallinity

, 2011
In order to analyze the antioxidant conversion rate of hydrogen peroxide as oxidant to make oxidation starch, and the change of starch crystallinity when mixing different amount of antioxidant, the determination of carboxyl content and X-ray diffraction ...

Human Gut Bacteria and Lipidic Nanoparticles: Particle Composition Predicts Structural Transformation and Bacterial Biocompatibility

Advanced Functional Materials, EarlyView.
Lipidic nanoparticles (LNPs) were incubated with 21 gut bacteria frequently associated with the human microbiome. SAXS revealed that ∼75% of tested species induced structural transformations in monoolein LNPs, whereas phytantriol and phospholipid formulations remained unaffected.

Strain‐Programmable Luminescent Adhesive Patch With Tartrazine‐Mediated Optical Skin Clearing for Photochemical Tissue Bonding

Advanced Functional Materials, EarlyView.
We propose a suture‐complementary approach that integrates optical skin clearing with a strain‐programmable luminescent adhesive patch. Hyaluronic acid promotes transdermal delivery of tartrazine to improve optical clearing and stabilizes its interaction with a photosensitizer. Optical clearing increases the penetration depth of visible light into skin,

Crystals and crystallinity in polymers diffraction analysis of ordered and disordered crystals

, 2014
"Polymeric crystals are more complex in nature than other materials' crystal structures due to significant structural disorder present. In fact, they actually exist in a semicrystalline state where the crystals are embedded in an amorphous phase to ...
