Sone052mp4 Work May 2026

I need to consider possible typos. Could "sone052mp4" be "Sono52MP4"? Maybe a conference or a specific material code? Alternatively, the user might be looking for a paper in solid-state communications related to MP4 materials. However, MP4 is more related to video compression, so that seems off. Maybe "MP4" here is part of a material classification, like a compound's designation?
