Polyimide‐Linked Hexaazatriphenylene‐Based Porous Organic Polymer with Multiple Redox‐Active Sites as a High‐Capacity Organic Cathode for Lithium‐Ion Batteries

Advanced Materials, EarlyView.
A high‐capacity polyimide‐linked porous organic polymer (HAT‐PTO) incorporating numerous redox‐active centers is synthesized via a hydrothermal reaction, delivering a high theoretical capacity of 484 mAh g−1. In situ hybridization with carboxyl‐functionalized multiwalled carbon nanotubes enhances conductivity and stability, achieving 397 mAh g−1 at C ...

Embedded Fe‐Cu Pairs Enable Tandem Nitrate‐to‐Ammonia Electroreduction

Advanced Materials, EarlyView.
A tandem Fe‐Cu pair catalyst, composing a single copper atom (Cu–N3) coordinated to adjacent iron clusters (Fe3N8), is designed. The electron‐deficient copper sites markedly enhance nitrate adsorption, while the electron‐rich iron clusters facilitate nitrite adsorption and water activation, thereby accelerating the electroreduction of nitrate and ...

Nitrite metabolism in the cyanobacterium Anabaena cycadeae: Regulation of nitrite uptake and nitrite reductase by ammonia [PDF]

FEMS Microbiology Letters, 1992
Nitrogen regulation of nitrite uptake and nitrite reductase was studied in the cyanobacterium Anabaena cycadeae and its glutamine-auxotrophic mutant. The development of the nitrite-uptake system preceded, and was independent of, the development of nitrate reductase.

Polyethyleneimine‐Modified Biosorbent Based on Banana Pseudostem Biomass for Environmental Remediation and Food Analysis

Advanced Sustainable Systems, EarlyView.
Biosorbents derived from banana pseudostem are functionalized with polyethyleneimine, with or without glutaraldehyde, and evaluated for dye removal and solid‐phase extraction. The materials exhibit high adsorption capacities and broad pH applicability in dye removal, while computational studies reveal amino groups as key interaction sites.
