An unsolved problem is how to produce efficiently and economically. Quickly with a quickly with a thin film of the organic compound in the solution, dried by a by a semiconductor layer. But for big arrays like displays, this layer must be patterned into electrically isolated devices. In that requires one or more additional steps, which do costly, time consuming and / or difficult to precisely.

Conventional semiconductors which require high-temperature processing steps, organic semiconductor devices can be made at room temperature. They could be built on flexible polymers instead of rigid silicon wafers.Interventions.. A team promoted to Dr.
The highest total levels of activity has been Join whereas long summer days . To researchers suggest that the main difference between long days and a short or medium term day from 17.00 and 20 to what would be expected if sunlight instead weather Been the decisive factor been. Besides outlook after the capture at statement inclement weather stayed constantly . Goodman says: ‘The fact that more time outdoors more time outdoors and are physically active total of in these longer days may important in a populations layer to promote their a fitness or in the prevention of adiposity in children This strengthens arguments for public health.
The study – published in the Journal of Physical Activity and Health – determined that child were physically active at on long summer days, with the biggest effects from 17.00 bis 08.00 clock by day longer. It is important to, light rather than the weather be like keeps a key, view of the authors , because the effect was strongest in the late afternoon and early evening, and because remained unchanged, considered although inclement weather has..
