Article Synopsis
- - A new species of roughy fish from the genus Hoplostethus, specifically the subgenus Leiogaster, has been identified based on three specimens from Sumatra, Indonesia.
- - This new species can be recognized by specific features such as the gular region having ctenoid scales, a smooth pelvic-fin spine, and distinct measurements of the head and pectoral fins.
- - The study also includes a detailed comparison with similar species and discusses the diagnostic traits of related species like Hoplostethus rubellopterus and Hoplostethus melanopus.
Photons do not carry sufficient momentum to induce indirect optical transitions in semiconducting materials, such as silicon, necessitating the assistance of lattice phonons to conserve momentum. Compared to direct bandgap semiconductors, this renders silicon a less attractive material for a wide variety of optoelectronic applications. In this work, we introduce an alternative strategy to fulfill the momentum-matching requirement in indirect optical transitions.
View Article and Find Full Text PDFMetal-mediated base pairing of DNA has been a topic of extensive research spanning over more than four decades. Precise positioning of a single metal ion by predetermining the DNA sequence, as well as improved conductivity offered by the ions, make these structures interesting candidates in the context of using DNA in nanotechnology. Here, we report the formation and characterization of conjugates of long (kilo bases) homoguanine DNA strands with silver ions.
