WebThe Milne metric follows when the scale factor of the FRLW metric is a constant over time, yielding: ds2 = c2dt2 − dr2 − r2dΩ2. where: dΩ2 = dθ2 + sin2θdφ2. r gives the proper … WebMilne, Adele M. ; Zhao, Jianhua ; Green, Martin A. A new silicon solar cell structure, the passivated emitter and rear cell, is described. The cell structure has yielded independently confirmed efficiencies of up to 22.8%, the highest ever reported for a silicon cell. Publication: Applied Physics Letters Pub Date: September 1989 DOI:

WebWe study an unconventional cosmology, in which we investigate the consequences that antigravity would pose to cosmology. We present the main characteristics of the Dirac-Milne Universe, a cosmological model where antimatter has a negative active gravitational mass. In this non-standard Universe, separate domains of matter and antimatter coexist at our … Web12 nov. 2008 · ABSTRACT We have performed a first-principles density functional theory investigation of the penetration of helium atoms through a graphene monolayer with defects. The relaxation of the graphene layer caused by the incoming helium atoms does not have a strong influence on the height of the energy barriers for penetration. healthcare ireland group jobs
