Recent progress of density functional theory studies on carbon-supported single-atom catalysts for energy storage and conversion.

Single-atom catalysts (SACs) have become the forefront and hotspot in energy storage and conversion research, inheriting the advantages of both homogeneous and heterogeneous catalysts. In particular, carbon-supported SACs (CS-SACs) are excellent candidates for many energy storage and conversion applications, due to their maximum atomic efficiency, unique electronic and coordination structures, and beneficial synergistic effects between active catalytic sites and carbon substrates. In this review, we briefly review the atomic-level regulation strategies for optimizing CS-SACs for energy storage and conversion, including coordination structure control, nonmetallic elemental doping, axial coordination design, and polymetallic active site construction.

Solvent Engineering-Enabled Surface Defect Passivation in Cu2ZnSn(S,Se)4 Solar Cells with Low Open-Circuit Voltage Losses and Improved Carrier Lifetime.

The efficiency of earth-abundant kesterite Cu2ZnSn(S,Se)4 (CZTSSe) solar cells has been lagging behind the Shockley-Queisser limit primarily due to the presence of deep-level defects. These deep-level defects cause critical issues such as short carrier diffusion length, significant band tailing, and a large open-circuit voltage (VOC) deficit, ultimately leading to low device efficiency. To address these issues, we propose a post-fabrication defect healing strategy by dip-coating the CZTSSe film in dimethylformamide (DMF) solvent.

Traumatic brain injury (TBI) is a leading cause of death and disability worldwide, with limited effective treatment strategies. Endogenous neural stem cells (NSCs) give rise to neurons and glial cells throughout life. However, NSCs are more likely to differentiate into glial cells rather than neurons at the lesion site after TBI and the underlying molecular mechanism remains largely unknown.

Beating the Size-Dependent Limit with Spin-Lattice Coupling in Nanomagnetism.

Further miniaturization of magnetic nanomaterials is intrinsically accompanied by a reduction in spin ordered domains, resulting in size-dependent magnetic behaviors. Consequently, a longstanding roadblock in the advancement of nanodevices based on magnetic nanomaterials is the absence of a method to beat the size-dependent limit in nanomagnetism. Here, we discover and exploit a spin-lattice coupling effect in three-dimensional freestanding magnetic nanoparticles to beat the size-dependent limit for the first time.
