An investigation on injectable composites fabricated by 45S5 bioactive glass and gum tragacanth: Rheological properties and in vitro behavior

The injectable composites were formulated from melt-derived 45S5 bioactive glass powder and gum tragacanth. The effect of tragacanth concentration (2 and 4 w/v%) and powder to liquid ratio (P/L= 1.5 to 2.5) on rheological properties, injectability, degradation, swelling, and bioactivity the composites was studied. With the increase of P/L ratio and tragacanth concentration, the force requ...

Flexible n-Type Tungsten Carbide/Polylactic Acid Thermoelectric Composites Fabricated by Additive Manufacturing

Flexible n-type tungsten carbide/polylactic acid (WC/PLA) composites were fabricated by additive manufacturing and their thermoelectric properties were investigated. The preparation of an n-type polymer-based thermoelectric composite with good stability in air atmosphere via additive manufacturing holds promise for application in flexible thermoelectric devices.
