To understand the impact of probed sensors on local electrode lithiation mechanisms, we studied two graphite | |NMC622 lithium-ion battery cells: i) a commercial multi-layered prismatic cell in jelly-roll configuration equipped with a reference electrode and an optical fiber, and ii) a paren...
Rechargeable sodium batteries are receiving increasing attention as potential technology for large﹕cale energy storage systems owing to the abundant nature and low cost of Na. Replacing the commonly used nonaqueous liquid electrolytes with polymer solid electrolyte s, is expected to provide new ...
Etching (often considered as decomposition) is one of the key considerations in the synthesis, storage, and application of metal nanoparticles. However, the underlying chemistry of their etching process still remains elusive. Here, we use real-time elect
However, the realization of the theoretical value of these materials still faces significant challenges, such as the need for a deep understanding of the energy storage mechanism of MOFs. The metal atoms used in MOFs is known to be critical to their properties and extensive studies on the ...
residing in the harsh natural sources often exhibit inherent desirable properties of high thermal stability, resistance to organic solvent, and long-term storage. The comprehensive metagenomic investigation of the ecological niches facilitates taxonomic binning, and the assessment of the metabolic and ...
The average postmortem interval (PMI) prior to the collection of brain specimens was 19.6±1.89 (hours). The average pH of the brain tissue for this group was 6.58±0.08. The average freezer storage time at the time of this investigation was 11.67±3.40 (years). Assessment of postmortem ...
First, general recommendations for the design of efficient NGCs are provided with special attention to electrospun NGCs. Then, the mechanisms underlying electrical stimulation of neural tissue regeneration are thoroughly considered. Next, published findings about nerve scaffolds based on PVDF, PLLA, PHB...
