Formation and Characterization of Insoluble Anthocyanins‐λ‐carrageenan Biopolyelectrolyte Complexes: Structural Morphology, Thermal Stability, and Release Dynamics

open access: yesChemFoodChem, EarlyView.
Insoluble biopolyelectrolyte complexes formed between blackberry anthocyanins and λ‐carrageenan are investigated. Optimal complexation occurs at low carrageenan ratios and acidic pH, producing porous hydrogel‐like structures with enhanced thermal stability.

Integrating-sphere coating [PDF]

open access: yes, 1973
Sodium chloride, used with proper solvent-dispersant combination, forms very durable reflective coatings. Several other inorganic salts, such as barium sulfate, barium carbonate, sodium fluoride, potassium chloride, sodium hexafluorosilicate, and ...

Enhancing Stability of Metallic Magnesium Nanoparticles toward Oxidation in Water via PEG‐Phosphonate Passivation

open access: yesChemistry – A European Journal, EarlyView.
Metallic magnesium nanoparticles are stabilized against rapid oxidation in water through surface passivation with phosphonic acid–terminated poly(ethylene glycol). By controlling the timing of ligand addition during synthesis, nanoparticle growth, morphology, and aqueous lifetime are tuned, extending stability from minutes to hours while preserving ...

Production of Ultrafine, High-purity Ceramic Powders Using the US Bureau of Mines Developed Turbomill [PDF]

open access: yes, 1993
Turbomilling, an innovative grinding technology developed by the U.S. Bureau of Mines in the early 1960's for delaminating filler-grade kaolinitic clays, has been expanded into the areas of particle size reduction, material mixing, and process reaction ...

Development of Nanofluids for Perdurability in Viscosity Reduction of Extra-Heavy Oils

open access: yesEnergies, 2019
The primary objective of this study is the development of nanofluids based on different diluent/dispersant ratios (DDR) for extra-heavy oil (EHO) viscosity reduction and its perdurability over time.

C‐Terminal Nucleobase Modification Amplifies Peptide‐Mediated Liposome Fusion

open access: yesChemistry – A European Journal, EarlyView.
Let's come together right now. Cationic peptides are known to promote aggregation of negatively charged liposomes through electrostatic interaction. The process is reversible: once neutrality is achieved, liposomes disaggregate. Here, we demonstrate that end‐capping peptides with nucleobases turns the process into irreversible fusion.

Anodization process produces opaque, reflective coatings on aluminum [PDF]

open access: yes, 1965
Opaque, reflective coatings are produced on aluminum articles by an anodizing process wherein the anodizing bath contains an aqueous dispersion of finely divided insoluble inorganic compounds. These particles appear as uniformly distributed occlusions in
