The investigation of novel cell-to-cell interconnection methods has gained importance with the increase wafer sizes. Shingling (i.e., overlapping) solar cells is not only a solution for smaller but also chance to output power density by (i) increasing active cell area within module, (ii) decreasing shading losses, and (iii) reducing electrical losses. Replacing commonly used expensive materials...

Oil-impregnated paper condenser transformer bushings are an important part of equipment, and partial discharge (PD) occurred when defects exist on the aluminum foil layers. Firstly, to study PD process oil-paper insulated capacitance graded bushing with defect broken foil, a defective sample is constructed parameters capacitance, carbonization traces at different voltage levels. Then, in order ...

The Aims of this study are to determine the effect embossing roll roughness and forming temperature on damage menthol-coated aluminum foil packaging, best quality menthol coating packaging. In study, independent variables were embossed wave (roughness level 1000,500.0 µm) (22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46 °C) be manipulated, observed, measured know with dependent variable. And...

Abstract This study utilizes a hot water treatment (HWT) method for introducing antibacterial properties to aluminum (Al) surfaces, which has relevance in several industries ranging from food packaging and ventilation systems biomedical materials. The HWT process can produce nanostructured oxide layer on wide range of metallic materials by simply immersing the metal at temperatures 75 °C 95 °C....

Introduction: The samples from the Stardust space probe will offer the first opportunity for analyzing cometary matter collected under controlled conditions together with contemporary interstellar dust particles [1, 2]. Moreover, Stardust is the first sample return mission ever that provides material from a known solar system object other than the moon. The primary goal after sample arrival is ...

We demonstrate the generation of patterns on overhead projector paper (OHP) and glass slides with the dimension at the submicron scale and in various colors. We have used the commercially available permanent marker pen to write lines on the surface of OHPs and glass slides and transferred the patterns of a compact disk (CD) onto the line. Observation under an optical microscope exhibited variou...

Anodization of Al foil under low voltages of 1-10 V was conducted to obtain porous anodic aluminas (PAAs) with ultrasmall nanopores. Regular nanopore arrays with pore diameter 6-10 nm were realized in four different electrolytes under 0-30°C according to the AFM, FESEM, TEM images and current evolution curves. It is found that the pore diameter and interpore distance, as well as the barrier lay...
