High-performance polymer solar cells via Al-doped ZnO cathode interlayer
Recently accomplished landmark power conversion efficiency (PCE) over 10% of polymer solar cells (PSCs) presents promising potential for the practical application of the printable photovoltaics. However, for achieving the top-level performances, particular design and huge effort have
Alcohol and prostate cancer risk
In a large follow-up study, we found that heavy regular alcohol consumption and binge drinking during midlife were associated with a significantly increased risk of prostate cancer risk. Specifically, men who were heavy drinkers (>14 drinks/week) were
Patterns of mutation in cancer genes
In most cancers, the majority of the changes to the DNA (termed mutations), acquired during the disease process are inconsequential in terms of driving the cancer, however a few of the changes in a small set of
Rating perceived exertion using facial expressions for children
Workload or exercise level can be subjectively or objectively assessed. Heart rate (HR), oxygen uptake, and blood lactate level are often used to objectively assess workload or exercise level. These physiological responses can be measured using instruments.
