Launch-vehicle primary structures like cylindrical shells are increasingly being built as monolithic composite and sandwich composite shells. These imperfection sensitive shells are subjected to axial compression due to the weight of the upper structural elements and tend to buckle under axial compression. In the case of composite shells the buckling load and imperfection sensitivity depend on the...
Neuronal oscillations have been shown to be associated with perceptual, motor and cognitive brain operations. While complex spatio-temporal dynamics are a hallmark of neuronal oscillations, they also represent a formidable challenge for the proper extraction and quantification of oscillatory activity with non-invasive recording techniques such as EEG and MEG. In order to facilitate the study of neuronal...
In this paper we present the latest R&D results of Q.Cells' high-efficiency solar cell and module concept Q.antum that is currently transferred into mass production. The current work is focused on solar cells and modules produced in our Reiner-Lemoine Research Center. Our optimized rear passivation concept in combination with innovations on the front side of the solar cell resulted in record module...
The fluorescence of p-N,N-dimethylaminobenzonitrile (DMABN) in molecular sieve pores of ZSM-5 shows two maxima. However, these maxima are located at shorter wavelengths compared with DMABN in solutions. In addition, the polarizations of both bands are different compared with the fluorescence polarizations in solutions. In molecular sieve pores, the high energy emission is positively, the low energy...
