Light sources based on reliable and energy-efficient light-emitting diodes (LEDs) are instrumental in the development of solid-statelighting (SSL). Most research efforts in SSL have focused on improving both the intrinsic quantum efficiency (QE) and the stability oflight emitters. For this reason, it is broadly accepted that with the advent of highly efficient (QE close to 1) and stable emitters, thefundamental research phase of SSL is coming to an end. In this study, we demonstrate a very large improvement in SSL emission (above70-fold directional enhancement for p-polarized emission and 60-fold enhancement for unpolarized emission) using nanophotonicstructures. This is attained by coupling emitters with very high QE to collective plasmonic resonances in periodic arrays of aluminumnanoantennas. Our results open a new path for fundamental and applied research in SSL in which plasmonic nanostructures are able tomold the spectral and angular distribution of the emission with unprecedented precision.

SARS-CoV-2 is a novel RNA coronavirus responsible of a deadly pandemic: the clinical illness COVID-19. With only one authorized drug for emergency use in critically ill patients: Remdesivir, there is not any other approved drug or vaccine yet with proven potential to overcome this infection. We exposed here many scientific evidences to support our novel idea that a macrolide, basically Clarithromycin, could be effective as a single agent for treatment and prophylaxis of COVID-19. Clarithromycin could change the history of this pandemic. It could reduce the costs of treatment and the potential adverse effects when combining more than one drug such as with Hydroxychloroquine. Clarithromycin treatment and prophylaxis as a single agent could be much more simple, safe and cheaper as giving Chloroquine or Hydroxychloroquine alone or in combination with Azithromycin as well as other therapeutic options.

太阳能电池可以将光能直接转化为电能，长期以来一直是人们寄予厚望的满足人类未来能源需求的新型环保能源．可是太阳能电池目前的发展状况却是不尽如人意，低下的发电效率使它的发电成本居高不下，极大地影响了它在现实中的应用．造成太阳电池效率低下的一个主要原因就是有太多的光能被它反射出去而白白浪费掉．如果能提高光能的利用率就可以大大提高太阳能电池的效率．
