The performance of whey protein isolate (WPI) and pectin as wall materials in encapsulation of Ziziphora clinopodiodes essential oil by ultrasonication method was compared. In this regard, using the response surface methodology, the influence of ultrasonication (US) power (50-150W) and core-coating ratio (10-100%) on the properties of microcapsules was evaluated. Increasing US power and core-coating ratio, caused to increase and decrease the particle size, respectively. The polydispersity index (PDI) of WPI coated microcapsules was increased by increasing of US power. The Zeta potential values were increased by increasing of core-coating ratio. Also, the effect of core-coating ratio on encapsulation efficiency was more than US power. Morphological studies by SEM on optimized microcapsules showed regular spherical shapes. X-ray diffraction analysis revealed that the type of the wall material had no effect on the structural properties of the microparticles. FT-IR analysis confirmed the pronounced effect of electrostatic interactions in the formation of microcapsules.

The purpose of this study was to optimize black garlic encapsulation parameters (core/coating ratio, extract concentration, and coacervate/maltodextrin [MD] ratio) using central composite design of the response surface methodology based on encapsulation efficiency (EE) (%). The optimum parameters were determined as 4.0 for the coating material/core ratio, 50% for the extract concentration, and 6.

Structures and their components experience substantially large vibration amplitudes at resonance, which can cause their failure. The scope of this study is the utilization of silicone-coated steel balls in concrete as damping aggregates to suppress the resonance vibration. The heavy steel cores oscillate with a frequency close to the resonance frequency of the structure.

Resonance vibration of structures is an unpleasant incident that can be conventionally avoided by using a Tuned Mass Damper (TMD). The scope of this paper contains the utilization of engineered inclusions in concrete as damping aggregates to suppress resonance vibration similar to a TMD. The inclusions are composed of a stainless-steel core with a spherical shape coated with silicone.
