Test printed circuit test boards (PCBs) with various surface finishes were subjected to a mixed flowing gas environment with gaseous composition adjusted to achieve a targeted 500600 nm/day copper corrosion rate. Board surface finishes included immersion silver (ImAg), organic solderability preservative (OSP) and lead-free hot-air-solder leveling (Pbfree HASL). The PCB test specimens were prepa...
A composite catalyst of rosin carbon/Fe3O4 with marvellous morphology was synthesized and applied as a counter electrode (CE) in dye-sensitized solar cells (DSCs), demonstrating notable electrocatalytic activity for the reduction of I3(-). Based on this CE, a high power conversion efficiency of 8.11% was achieved, comparable to that of the traditional Pt CE.
Pine rosin of Pinus merkusii Jung at de Vriese is produced industrially from a distillation process pine sap. The high total Indonesian production leads the primary derivatization strategy into several derivates to fulfill market demand. Abietic acid (AA) major compound in rosin, used as object observation this study. general methodology for transformation reported involves using palladium (Pd)...
Colophonium (rosin, CAS no. 8050-09-7) is a complex mixture of >100 different compounds derived from pine trees. It is a good tackifier, can be used as an emulsifier, and has acid properties without causing corrosion. Because of these properties, colophonium is used in various products, such as soldering fluxes, paper, cosmetics (depilatory waxes, soaps, hair gel, and nail polish), cutting flui...
