Influence of scaffold geometry on the degradation rate of 3D printed polylactic acid bone scaffold.

Fabricating scaffolds using three-dimensional (3D) printing is an emerging approach in tissue engineering (TE), where filaments with a controlled arrangement are printed. Using fused deposition modeling in bone replacement enables the simulation of bone structure. However, the microenvironment created by the scaffold must meet specific requirements.

Sensing of Acetaminophen Drug Using Zn-Doped Boron Nitride Nanocones: a DFT Inspection.

During environmental testing, scientists face the problem of developing and designing a new type of sensor electrode with distinguished stability, high activity, and cost-effectiveness to detect acetaminophen (ACE). Density functional theory (DFT) calculations were used to investigate the interaction and electrical response of Zn-doped and pristine boron nitride nanocones (BNNCs) with and to ACE with the disclination angle of 240°. The adsorption energy for ACE in the Zn-doped was - 56.
