“…Aldol condensation, transesterification in biodiesel production, and Schiff base formation have been reported to be catalyzed using ACE. [8][9][10][11][12] In the previous study, some salts and bases, such as KCl, KNO3 and KOH were impregnated onCaO-based catalyst to improve their catalytic activity. [13][14][15] Hu et al prepared KNO3/CaO via dry impregnation method and applied it for glycerol carbonate synthesis.…”

Potassium nitrate impregnated on activated chicken eggshell (KNO3/ACE) was successfully prepared, and then it was characterized by means of IR, XRD, FESEM and EDAX spectroscopy. The KNO3/ACE showed high activity for the synthesis of chalcone compound, (2E,4E)-1,5-diphenylpenta-2,4-dien-1-one (3) from the reaction between acetophenone (1) and cinnamaldehyde (2). The highest yield of compound 3 was achieved up to 93% after reaction at 60 o C for 2 h in the presence of 15 wt% catalyst. Then, compound 3 was further treated with hydrazine hydrate (4) to produce (E)-3-phenyl-5-styryl-1H-pyrazole (5) up to 97% yield using the same optimized condition as in chalcone synthesis.

“…Techniques for impregnating liquids into metal meshes have a variety of applications in a wide range of fields, [1][2][3] such as the fluoropolymer coating 4,5) of meshes used for conveyor belts or insulation materials. For the efficient impregnation of droplets into meshes, it is necessary to improve the wettability between the droplets and the meshes, where the wettability refers to the ease of a droplet adhering to a solid surface.…”

For efficient impregnation, it is important to improve the wettability between the samples used. However, the traditional impregnation method using ultrasonic waves suffers from the following problems: that the vibration source must be brought into direct contact with the sample and impregnation with liquids with high viscosities is difficult. Also, the method has the possibility that impurities will be mixed in the sample when bringing the ultrasonic vibration source directly into contact with the sample. Therefore, we investigated the use of intense aerial ultrasonic waves as a new noncontact method of impregnating into meshes while observing the extent of the droplet spread. In this study, we observed droplet deformation and impregnation when changing the droplet volume and input power and after installing a sound waveguide for focusing the sound wave. Consequently, we were consequently able to demonstrate the impregnation of droplets into the mesh.

“…Recently, researcher's attention has been paid to heterocycles containing nitrogen atom, particularly pyrazoles and their derivatives [10]. They have been found to denote versatile biological activities such as monoamine oxidase inhibitor [11,12], antihepatotoxicity [13,14], antileishmanial [15][16][17], anti-inflammatory [18][19][20], antiproliferative [21], tissue non-specific alkaline phosphatase inhibitor [22], cyclin-dependent kinase inhibitor [23], anticancer [24][25][26][27], antimicrobial [28][29][30], and antioxidant [31][32][33]. Development of novel chemical structures of pyrazole derivatives is currently a trending topic due to their wonderful biological actions [34][35][36][37].…”
