Báo cáo hóa học: " Periodically Aligned Si Nanopillar Arrays as Efficient Antireflection Layers for Solar Cell Applications" ppt

... fabrication of PASiNP-based solar cell is similar to the traditional Si solar cell technology. After removal of residual PS spheres and silver particles on the surface of PASiNP arrays, a thin ... respectively. For the solar cell without PASiNP arrays, as shown in Fig. 5b, the V OC is almost the same as the device with PASiNP arrays, but the J SC is only half of that ob...

... lines), as the number of sessions passing through a GW increases, latency of code update for a single session increases linearly, but for SET sessions, as the number of sessions increases, as a ... setup, SM at SN assigns separate buffer for each TM session. Initially, this buffer is the same for each session. Later on, SM dynamically adjusts the buffer for each session by measur...

... phosphati- dylinositol-3 kinase (PI3K) attenuates ROS production. These findings suggest that these kinases are involved in upstream signaling cascades responsible for activating NADPH oxidase assembly ... activation of the src-family kinases Lyn and Fyn as well as the tyrosine kinase Syk [30,32,52]. Activation of these signaling cascades are linked to the synthesis and secretion of pro...

We assume that phase variations ... 0.5 for a sub-block size of N b = 100 symbols. Through simulations, we found that the code with sub-block size of 100 symbols gives the best BER performance for the amounts of phase noi...

In order to evaluate the formation of defects on the nanotube surface by the ECR plasma treatment using different gas compositions, ... defect density on the walls of the MWCNTs [30]. Therefore, the intensity ratio can be used to evaluate the formation of defects which are preferential sites for functionalization. As...
