Magnesium-based hydrogen storage materials represent a hydrogen storage technology with broad application prospects. As the global energy crisis and environmental pollution issues become increasingly severe, hydrogen, as a clean and efficient energy source, has garnered growing attention. Magnesium-based hydrogen storage, serving as a crucial means for storing and transporting hydrogen, is gaining prominence due to its abundant resources, low cost, low density, and high hydrogen storage density. However, challenges in terms of absorption/ desorption rates, temperature, activation energy, and enthalpy during hydrogen application impede its development. To address these challenges, this paper systematically reviews current research on magnesium-based hydrogen storage materials, encompasses their types, characteristics, and hydrogen absorption mechanisms. Furthermore, it delves into the impacts of nanoscale dimensions, alloying, doping, and catalysis on the performance of magnesium-based materials. The aim is to provide valuable insights for research in related fields.

Necrotizing enterocolitis(NEC)is a devastating gastrointestinal disease over decades,which,however,remains the leading cause of morbidity and mortality in preterm infants.^([1])Although multiple factors,including gastrointestinal tract bacterial colonization,immaturity,and formula feeding,are reported to be involved in the pathogenesis of NEC,the precise mechanisms are not well *** to the advances in metagenomic sequencing,ample evidences have illustrated the presence of gut dysbacteriosis in infants with NEC,which is characterized by an elevated abundance of Proteobacteria,reduced abundance of Firmicutes phyla,and an overall decrease in bacterial diversity,providing novel insights into NEC progression.^([1,2])Additionally,the bacterial replication rates,particularly those of Enterobacteriaceae,rapidly increase two days prior to NEC diagnosis.^([2])
