Analysis of the expanding thermal argon-oxygen plasma gas phase

, 2003
An expanding thermal argon plasma into which oxygen is injected has been analyzed by means of Langmuir and Pitot probe measurements. Information is obtained on the ion d. profile and the flow pattern in the downstream plasma.

Structural and Physical Properties of Glutamic Acid Oligopeptide‐Modified Silk Fibroin

Macromolecular Materials and Engineering
Silk fibroin (SF) exhibits excellent properties as a safe biomaterial. Although blending SF with certain polymers enhances its properties, such as its flexibility, degradability, and cell affinity, this integration also presents some challenges.

Impact of MgO Additions on the Oxidation Resistance and Compression Behavior of Vanadium Alloys

Advanced Engineering Materials, EarlyView.
An increase in oxidation resistance at 600 °C is achieved for alloys containing more than 2.5 wt.% MgO. It has been established that, along with V2O5, MgO6V2, and Mg2O7V2 are formed, which are presumed to enhance oxidative stability. Furthermore, the possible transformation of Mg‐vanadates through reaction with CO2, which presumably occurs in this ...
