Abstract Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron sublineages BA.2.12.1, BA.4 and BA.5 exhibit higher transmissibility than the BA.2 lineage 1 . The receptor binding immune-evasion capability of these recently emerged variants require immediate investigation. Here, coupled with structural comparisons spike proteins, we show that (BA.4 are hereafter referred collectively to as BA.4/BA.5) similar affinities for angiotensin-converting enzyme (ACE2) receptor. Of note,...
Abstract SARS-CoV-2 Omicron sublineages BA.2.12.1, BA.4 and BA.5 exhibit higher transmissibility over BA.2 1 . The new variants’ receptor binding immune evasion capability require immediate investigation. Here, coupled with Spike structural comparisons, we show that BA.2.12.1 BA.4/BA.5 comparable ACE2-binding affinities to BA.2. Importantly, display stronger neutralization than against the plasma from 3-dose vaccination and, most strikingly, post-vaccination BA.1 infections. To delineate...
Perovskite solar cells (PSCs) are multilayer structures. The interface between electron transport layer and perovskite is the mechanical weakest point in flexible PSCs due to its low fracture energy.
