Silica Coating on Carbonaceous Mesophase Spherules

Oxygen Isotope Ratios of Large Cosmic Spherules: Carbonaceous and Ordinary

Introduction: Based on petrographic and ion probe investigation of small micrometeorites (150–250 μm), previous studies (e.g. [1]) have concluded that 99% of them should come from carbonaceous, possibly cometary parent bodies (CM/CR related). Our oxygen isotope measurements of 33 large (>500 μm) silicate type cosmic spherules (CS), using IR-laser fluorination/mass spectrometry, indicate that 30...

Electrophoretic silica-coating process on a nano-structured copper electrode.

A method for silica-coating at the nanoscale by electrophoretic deposition is presented here, using raw or grafted silica dispersions.

Reducing ZnO nanoparticles toxicity through silica coating

ZnO NPs have good antimicrobial activity that can be utilized as agents to prevent harmful microorganism growth in food. However, the use of ZnO NPs as food additive is limited by the perceived high toxicity of ZnO NPs in many earlier toxicity studies. In this study, surface modification by silica coating was used to reduce the toxicity of ZnO NPs by significantly reducing the dissolution of th...
