Abstract All-solid-state batteries incorporating lithium metal anode have the potential to address energy density issues of conventional lithium-ion that use flammable organic liquid electrolytes and low-capacity carbonaceous anodes. However, they suffer from high ion transfer resistance, mainly due instability solid against metal, limiting their in practical cells. Here, we report a complex hydride superionic conductor, 0.7Li(CB 9 H 10 )–0.3Li(CB 11 12 ), with excellent stability...

Rechargeable Ca batteries offer the advantages of high energy density, low cost, and earth-abundant constituents, presenting a viable alternative to lithium-ion batteries. However, using polymer electrolytes in practical is not often reported, despite its potential prevent leakage preserve battery flexibility. Herein, Ca(BH
Lithium-sulfur batteries offer the highest theoretical energy density among enclosed rechargeable batteries. However, there are various issues that need to be addressed before their practical adoption, such as dissolution of intermediate lithium polysulfides (Li2Sn) into electrolyte solution, which causes rapid degradation battery. Herein, we used nuclear magnetic resonance (NMR) and in-situ imaging (MRI) visualize species formed during discharge–charge process in Li-S A strong enhancement...

The motion inside germanium-doped was investigated through pulsed-field gradient nuclear magnetic resonance spectroscopy temperature-dependent ionic studies. superior charge carrier mobility germanium enhanced...
In the present work, a novel approach has been made to evaluate extraction mechanism of neodymium (Nd) using trihexyl-tetradecyl-phosphonium benzoate (TTPB) ionic liquid through nuclear magnetic resonance (NMR) techniques. A detailed study on interactions between extractant and (IL) is presented. The
The use of Ca metal in battery technology is a promising approach owing to its high energy density and sustainability. However, the increased resistance during extended cycling significantly narrows application range. This study aimed improve long-term stability deposition by employing dual-salt strategy based on calcium monocarborane, Ca(CB11H12)2, which demonstrated favorable characteristics as single-salt electrolyte. addition LiBr Ca(CB11H12)2 resulted low even after 200 h contrast...
Treatment of metastatic lymph nodes (LNs) is challenging due to their unique architecture and biophysical traits. Systemic chemotherapy fails impede tumor progression in LNs poor drug uptake retention by LNs, resulting fatal systemic metastasis. To effectively treat LN metastasis, achieving specific prolonged drugs the tumor-draining essential. The lymphatic drug-delivery system (LDDS) an ultrasound-guided methodology for administration that addresses these requirements. However, early-stage...
Complex hydrides have collected recent attention as a new class of solid electrolytes with potential applications in all-solid-state batteries. To improve ionic conduction the complex hydrides, multi-cation crystal structure can be attractive. It will allow tuning cation dynamics via modification depending on types and number additional cations. However, struggles inter-cation scattering among different address this issue, understanding mechanisms multi-cationic crystals is indispensable....
