In order to analyze the effects of various sizes of pyramid structure on solar cell characteristics, a pyramid structure was formed on the wafer through various etching processes.In this paper, etching was performed using one-step etching processes such as alkaline solution etching, reactive ion etching (RIE), and metal-assisted chemical etching (M
The average yield of bulb onions is still quite low.The purpose of this study was to improve the techniques and methods of cultivating onions using new generation preparations against the background of N180P60K60 in a drip irrigation method.To achieve the objective of this study, field surveys, observations and measurements were carried out using g
Clay soil and their related irregular behavior such as shrinkage, swelling, desiccation cracks etc.are the main concern for the construction of composite clay liner (CCL) in waste landfill site.In this study, an investigation was conducted on a scaled model of prototype landfill liner to quantify both the geometrical and morphological characteristi
A novel piezoelectric actuator using a two-stage flexure hinge structure is proposed in this paper, which is used in a compact and high-precision electromechanical field.The two-stage flexure hinge structure is used to provide horizontal thrust and vertical clamping force to the driving feet, which solves the problems of unstable clamping force and
