Earliest simultaneous multi-color optical observations of GRB 230328B: from 41 seconds to the host-galaxy identification

Abstract We present a multiwavelength study of the long-duration gamma-ray burst GRB 230328B, combining prompt γ-ray observations with exceptionally early simultaneous optical photometry and extensive X-ray, radio, and host-galaxy follow-up. NUTTELA-TAO began simultaneous g′r′i′...

Advanced hybrid nanofiltration membranes enabled by dual-zwitterionic locking for salt and heavy metal removal

The development of nanofiltration (NF) membranes is critical for achieving sustainable water purification and resource recovery. However, conventional polyamide NF membranes often encounter trade-offs between ion selectivity and water permeability. Herein, we introduce a dual-zwi...
