Multi‐Objective RSM Optimization of Emission and Performance Characteristics in a Diesel Engine Fueled With BaTiO3 Nano‐Enhanced Jojoba Biodiesel

Energy Science &Engineering, EarlyView.
This study uses response surface methodology to optimize Jojoba biodiesel blended with BaTiO3 nanoparticles in a single‐cylinder diesel engine. Results show that ~48.95–51.31 ppm of BaTiO3 achieves balanced performance and emission, decreasing CO and NOx while increasing torque and brake thermal efficiency.

Imaging Ionic Displacements Across Inclined Ferroelectric Domains by a Reciprocity Approach to 4D‐STEM

Small, EarlyView.
Four‐dimensional STEM comprises a vast portfolio of electron microscopy methods in one data set, conventional plane‐wave illumination TEM being one of them. Here, the principle of reciprocity is employed to produce true structural projections of misoriented ferroelectric domains at atomic resolution. By reciprocal TEM imaging from four‐dimensional STEM
