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.

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.

Nitrification-denitrification in WSP: a mechanism for permanent nitrogen removal in maturation ponds [PDF]
, 2009 A pilot-scale primary maturation pond was spiked with 15N-labelled ammonia (15NH4Cl) and 15N labelled nitrite (Na15NO2), in order to improve current understanding of the dynamics of inorganic nitrogen transformations and removal in WSP systems.

Gas‐ and Liquid‐Phase Catalysts for Solar‐Driven Catalytic Ammonia Decomposition
Advanced Sustainable Systems, EarlyView.Amid the drive toward carbon‐neutral hydrogen, this review analyzes photocatalytic ammonia decomposition in gas‐ and liquid‐phase systems. It examines catalyst families—TiO2, ZnO, Ru, single‐atom, and antenna–reactor designs. This study summarizes advances in bandgap tuning, active‐site and cocatalyst engineering, photothermal coupling, and machine ...

Lifespan‐Regulated CAR‐Macrophages from Myeloid Progenitors for Enhanced Colorectal Cancer Therapy
Advanced Science, EarlyView.Using a tamoxifen‐inducible Hoxb8 system, proliferative bone marrow progenitors can be generated, which are subsequently engineered with an anti‐CEA CAR construct containing a suicide gene (iCas9) and differentiated into CAR‐macrophages. This method facilitates scale up the production of CAR‐macrophages.

Oxidation of Native and Modified Hemoglobin and Myoglobin by Sodium Nitrate. Effect of Inositol Hexaphosphate [PDF]
, 1981 Native and modified hemoglobin, myoglobin and a and phemoglobin subunits were oxidized by sodium nitrite at pH 6. The experiments were carried out under oxy and deoxy conditions with and without inositol hexaphosphate (IHP).

Highly Ordered DNA Framework Interface Enables Efficient Enzymatic Oligonucleotide Synthesis
Advanced Science, EarlyView.Tetrahedral DNA nanostructures (TDN) ‐based nanoscopic interface provides ordered upright orientation and optimal spacing for initiator primers, enhancing enzyme accessibility in interfacial enzymatic oligonucleotide synthesis (EOS). Notably, efficient TDN‐based EOS is employed for DNA information storage by synthesizing a 60‐nucletide DNA fragment ...
