Quantum efficiencies remain a critical issue for general applications of semiconducting polymers in optoelectronics and others. In this work, we demonstrate that nearly 100% quantum efficiencies (η's) in thin solid films can be reached when the polymer molecules are mechanically stretched into molecular confinement. We selected three conjugated polymers of varied backbone stiffness and interchain coupling, prepared in both diluted and pristine states.

Methods: The liver fibrosis model was induced in male Wistar rats by administering 8 weeks of twice weekly CCL4 intraperitoneal injections without (untreated model) or with once daily FZHY (treated model). Normal, untreated rats served as the control group.
Purpose: Hepatitis C virus (HCV) infection causes chronic hepatitis in approximately 80 % of cases. Although it is well recognized that the immune system plays an important role in determining the outcomes of HCV infection, the underlying molecular mechanisms of persistent HCV infection and hepatic injury are incompletely understood. Tumor necrosis factor-α-induced protein 8-like 2 (TNFAIP8L2, TIPE2) is a newly identified negative regulator of innate and adaptive immunity.

However, disc rotation usually causes pixel migration, thus reducing signal quality. This study proposes a special geometrical arrangement to counteract pixel migration.
