On-Tip Polymerization Method for Multimodal Characterization of Nanoparticles with Electron/Ion Imaging and Atom Probe Tomography. [PDF]

Small Methods
This study presents an on‐tip polymerization method that employs a needle substrate with a designed through‐microchannel (“needle‐eye”) to retain a picoliter‐scale solution of nanoparticles. Using a resin precursor as the solution, polymerization is carried out in situ at the needle tip.

Comparative Transcriptome Analysis During the Seven Developmental Stages of Channel Catfish (Ictalurus punctatus) and Tra Catfish (Pangasianodon hypophthalmus) Provides Novel Insights for Terrestrial Adaptation

Frontiers in Genetics, 2021
Tra catfish (Pangasianodon hypophthalmus), also known as striped catfish, is a facultative air-breather that uses its swim bladder as an air-breathing organ (ABO). A related species in the same order (Siluriformes), channel catfish (Ictalurus punctatus),
