Nano-confined multi-synthesis of a Li-Mg-N-H nanocomposite towards low-temperature hydrogen storage with stable reversibility
No full textA Li–Mg–N–H system is a highly promising source of hydrogen storage materials due to its favorable thermodynamics and potential reversibility. Its application has been greatly hindered, however, by its rather high activation energy barriers. Herein, we report a novel multi-reaction methodology for the synthesis of nanosized Li₂Mg(NH)₂ space-confined into thin-film hollow carbon spheres (THCSs) with a uniform dispersion. It shows that a completely depressed release of ammonia and reversible hydrogen sorption at a temperature of 105 °C, the lowest temperature reported so far, were achieved for the nano-confined Li₂Mg(NH)₂. Furthermore, a stable cycling capacity close to the theoretical value was also successfully realized, even through up to 20 cycles of de-/re-hydrogenation.Guanglin Xia, Xiaowei Chen, Cuifeng Zhou, Chaofeng Zhang, Dan Li, Qinfen Gu, Zaiping Guo, Huakun Liu, Zongwen Liu and Xuebin Y
Hierarchical porous Li(2)Mg(NH)(2)@C nanowires with long cycle life towards sStable hydrogen storage
Full text linkThe hierarchical porous Li₂Mg(NH)₂@C nanowires full of micropores, mesopores, and macropores are successfully fabricated via a single-nozzle electrospinning technique combined with in-situ reaction between the precursors, i.e., MgCl₂ and LiN₃, under physical restriction upon thermal annealing. The explosive decomposition of LiN₃ well dispersed in the electrospun nanowires during carbothermal treatment induces a highly porous structure, which provides a favourable way for H₂ delivering in and out of Li₂Mg(NH) nanoparticles simultaneously realized by the space-confinement of the porous carbon coating. As a result, the thus-fabricatedLi₂Mg(NH)@C nanowires present significantly enhanced thermodynamics and kinetics towards hydrogen storage performance, e.g., a complete cycle of H2 uptake and release with a capacity close to the theoretical value at a temperature as low as 105°C. This is, to the best of our knowledge, the lowest cycling temperature reported to date. More interestingly, induced by the nanosize effects and space-confinement function of porous carbon coating, a excellently stable regeneration without apparent degradation after 20 de-/re-hydrogenation cycles at a temperature as low as 130°C was achieved for the as-prepared Li₂Mg(NH)₂@C nanowires.Guanglin Xia, Yingbin Tan, Dan Li, Zaiping Guo, Huakun Liu, Zongwen Liu and Xuebin Y

Particle Size and Particle-Size Distribution Effects on Li+ Extraction/Insertion Kinetics for Li-Rich Mn-Based Oxides
No full textA series
of Li-rich Mn-based layered material Li1.2Ni0.13Co0.13Mn0.54O2 (LMR) with
different particle sizes and particle-size distributions (PSDs) have
been successfully synthesized via a combustion method using different
manganese sources. The particle size of the N-LMR material prepared
using Mn(NO3)2·4H2O as the manganese
source is the smallest, and its PSD range is the narrowest among all
of the samples. The unique particle size and PSD have a great influence
on the electrochemical kinetics of Li-ion extraction/insertion reactions,
leading to enhanced electrochemical performance when used as a cathode
material for both the half and full Li-ion cells, especially the specific
charge capacity at high current rates. The value of the charge specific
capacity will determine the state of charge at the initial discharge
stage and then influence the discharge process of these Li-rich Mn-based
oxides. The N-LMR electrode delivers an initial discharge capacity
of 309.2 mA h g–1 at 0.1C, and the specific capacity
can reach up to 208.1 mA h g–1 at 1C. After 140
cycles, the electrode can still maintain 95.6% of its initial specific
capacity at 1C. Moreover, the material displays a superior high-temperature
lithium storage property at 55 °C and the full cells using N-LMR
as the cathode material also show a much better electrochemical performance

A comparison study of decomposition mechanisms of single-cation and double-cations (Li, Al) ammine borohydrides
No full textThe decomposition mechanisms of [Li(NH 3 )][BH 4 ], [Al(NH 3 ) 6 ][BH 4 ] 3 and [Al(NH 3 ) 6 ][Li 2 (BH 4 ) 5 ] were investigated using Density functional theory (DFT) calculation. The calculated results show that [Li(NH 3 )][BH 4 ] has low NH 3 vacancy formation energy and diffusion barrier, therefore ammonia would easily release at relatively low temperature. Both [Al(NH 3 ) 6 ][BH 4 ] 3 and [Al(NH 3 ) 6 ][Li 2 (BH 4 ) 5 ] show relatively high NH 3 vacancy formation energies and diffusion barriers, which avoid ammonia release at low temperature. In addition, the calculated H 2 formation energy barriers, i.e., [Al(NH 3 ) 6 ][Li 2 (BH 4 ) 5 ] < [Al(NH 3 ) 6 ][BH 4 ] 3 < [Li(NH 3 )][BH 4 ], are in agreement with the tendency of dehydrogenation temperatures determined experimentally. The incorporation of [BH 4 ] - into [Al(NH 3 ) 6 ][BH 4 ] 3 play an important role in decreasing the dehydrogenation temperature and improving the hydrogen purity of [Al(NH 3 ) 6 ][Li 2 (BH 4 ) 5 ]

Annexin A, expressed in vertebrates, has been implicated in a variety of regulated cell death (RCD) pathways, including apoptosis, autophagy, pyroptosis, ferroptosis, and neutrophil extracellular trap-induced cell death (NETosis). Given that inflammation is a key driver of cell death, the roles of Annexin A in inflammation have been extensively studied. In this review, we discuss the regulatory roles of Annexin A in RCD and inflammation, the development of related targeted therapies in translational medicine, and the application of animal models to study these processes. We also analyze current challenges and discuss future directions for improved diagnostic and therapeutic strategies.Keywords: Annexin A, regulated cell death, inflammation, translational medicin
