Purpose: This study aims to develop a free-breathing cardiac DTI method with fast and robust motion correction.
Methods: Two proposed image registration-based motion correction (MOCO) strategies, MOCO and MOCO, were applied to diffusion-weighted images acquired with M2 diffusion gradients under free-breathing. The effectiveness of MOCO was assessed by tracking epicardium pixel positions across image frames.

Constructing high cycling stability and rate performance under limited or ideally zero sodium excess, namely initially anode-free design, which can obtain the ultimate energy density of sodium metal batteries, is highly desired yet remains challenging. Here, highly ordered and regularly arranged Al(100) single crystal current collector is constructed based on the grain boundary migration theory through a simple high-temperature calcination method, which eliminates the diffusion resistance of Na migration at grain boundaries, reduces the nucleation overpotential and interface diffusion energy barrier, increases the Na transfer rate, and exhibits uniform reversible sodium deposition capability. Profiting from the modified current collector surface, the Al(100) electrode can be cycled stably for 500 cycles with a Coulombic efficiency of 99.

Lithium metal anodes (LMAs) are highly promising for high energy density batteries, but their practical application is limited by challenges such as dendrite formation, electrolyte depletion, and low coulombic efficiency (CE) due to the instability of the native solid electrolyte interphase (SEI) layer. Therefore, regulating Li-ion diffusion and electron transport is crucial for overcoming these issues and enhancing the performance of LMAs. This study introduces an inorganic-rich hybrid layer-coated carbon framework (IHL@CF) as a 3D lithiophilic host designed to stabilize and optimize the SEI layer.

Composite polymer electrolytes (CPEs) are considered among the leading contenders for next-generation all-solid-state lithium-metal batteries. However, CPEs simultaneously face multiple significant challenges, including reduced ion transference number, insufficient ionic conductivity, and poor cycling stability, which severely limit their practical applicability. Herein, we have designed a multifunctional unilamellar inorganic nanosheets (TiO) additive for CPEs with cationic defects which is capable of simultaneously addressing all aforementioned challenges.
