Purpose This study aims to make foamed polylactic acid (PLA) structures with different densities by varying deposition temperatures using the material extrusion (MEX) additive manufacturing process. Design/methodology/approach The multiplier (EM) was calibrated for each temperature control foaming expansion. Material density determined extruded cubes optimal EM value temperature. influence of o...

The number of people receiving facial filler injections is increasing as it relatively safe than the other cosmetic procedures. However, complications injection range from mild redness and inflammation to cerebral infarction. We report case a patient who was diagnosed with infarction intracranial hemorrhage after injection. A 61-year-old male presented emergency department ocular pain visual lo...

Design of a low-cost, eco-friendly, self-poled and flexible piezoelectric nanogenerator based on lead-free H 2 (Zr 0.1 Ti 0.9 ) 3 O 7 piezo-nanowires polylactic acid biodegradable piezopolymer.

Gelatin-hydroxyapatite-polylactic acid (PLA) nanocomposites were synthesized using five different formulations. The nanocomposites were loaded with ibuprofen and the amount of drug in the carriers was determined. X-ray diffraction (XRD) analysis was conducted before and after drug loading to ensure the presence of ibuprofen on the nanocomposites. Drug delivery was evaluated in phosphate buffere...
