Chromosome study of peled (Coregonus peled, Salmoniformes)
Folia Biologica, 2004 Chromosomes of Coregonus peled were examined by Giemsa, CMA3, Ag-NOR and C-banding. The karyotype of peled had a diploid number 2n=76, arm number NF=96 and consisted of twenty meta-submeta chromosomes and 56 subtelo-acrocentric chromosomes. C-positive blocks of heterochromatin were observed on the telomeric regions of meta- and submetacentric ...

Mixed‐Polymer Hole Transport Layers Reinforce Au‐Anode Top Emitting Perovskite Light Emitting Diodes
Advanced Science, EarlyView.Au‐anode corrosion is shown to occur rapidly under voltage bias in MAPbI3 perovskite LEDs. Resulting Au+ migration quickly leads to device shorting and unstable emission during constant current driving. We demonstrate that using a simple mixed‐polymer hole transport layer containing polyTPD and PVK can reduce Au‐corrosion and stabilize LED operation ...

Advanced Science, EarlyView.Metal‐anode batteries using Li, Na, Mg, and Ca offer exceptionally high energy density, but dendrites, unstable interphases, cracking, and pore formation hinder durability and safety. This review shows how careful electrolyte and interphase design can stabilize these reactive metals.
