Sublimable dye thermal transfer printer.

Transfer of bisphenol A from thermal printer paper to the skin.

Of 13 thermal printing papers analyzed, 11 contained 8-17 g/kg bisphenol A (BPA). When taking hold of a receipt consisting of thermal printing paper for 5 s, roughly 1 microg BPA (0.2-6 microg) was transferred to the forefinger and the middle finger if the skin was rather dry and about ten times more if these fingers were wet or very greasy. This amount transferred to dry skin was neither signi...

Measurement and compensation of printer modulation transfer function

bstract. The capacity of a printing system to accurately reproduce etails has an impact on the quality of printed images. The ability of system to reproduce details is captured in its modulation transfer unction (MTF). In the first part of this work, we compare three exsting methods to measure the MTF of a printing system. After a horough investigation, we select the method from Jang and Alleac...

Electron Transfer in Dye-Sensitized Nanocrystalline TiO2 Solar Cell

The dye-sensitized solar cells (DSSC) have been regarded as one of the most promising new generation solar cells. Tremendous research efforts have been invested to improve the efficiency of solar energy conversion which is generally determined by the light harvesting efficiency, electron injection efficiency and undesirable electron lifetime. In this review, various characteristics of dye-...
