In summary, we have developed an easy and scalable non-lithographic approach for creating sub-wavelength structured antireflection coatings directly on silicon nitride anti-reflection coatings for the first time to improve the solar cell efficiency.
We conduct a systematic study of the effect of various boundary conditions (bounce back and three versions of diffuse reflection) for the two-dimensional first-order upwind finite difference Lattice Boltzmann model.
The orange and red arrows show in the V L -V M projection of the calculated jumps by the first and second specular reflections, starting from the solar wind velocity for the first reflection (orange) and from the end point of the observed second ring (corresponds to second injection) for the second reflection.
When we first see Hanna X, she is looking at her reflection in a mirror for the first time in more than three years.
She then lies back and cups her belly with her hands, a gesture that suggests that this woman who, seconds before was captivated by, or just lost in, her own reflection, has begun, perhaps for the first time, to think about the life growing inside her.
The feasibility of functional imaging of neonatal brains was studied in a noninvasive transcranial manner by using reflection mode photoacoustic technique for the first time.
New freely available digital elevation data derived from the Shuttle Radar Topography Mission (SRTM-3) and the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) allow, for the first time, the use of area-wide high-resolution elevation models.
Variations of reflection and transmission coefficients for the first order of approximation of the corrugation versus angle of incidence, corrugation and angle between propagation and attenuation vectors are computed and depicted graphically.
