Summary: In this study, Ga2O3 nanoparticles with a size of about 4 nm were synthesized via a sol-gel method, and three types of carbon materials were employed to improve the conductivity of Ga2O3. Among the carbon materials, reduced graphene oxide was found to be the most effective in providing attachment points for Ga ions, leading to a more uniform distribution of Ga2O3 nanoparticles. The Ga2O3/rGO electrode showed stable capacity retention at a current density of 1000 mA g(-1) after 600 cycles, indicating a promising approach to enhance the electrochemical stability of Li-ion batteries.

Summary: The study synthesized four different MnO2 polymorphs with controlled morphology to investigate their influences in conversion-based materials. Experimental results showed that spinel-phased MnO2 was formed during charge storage reactions for all samples, but the electrochemical performance varied based on the initial crystal structure. Among the polymorphs, lambda-MnO2 exhibited the highest reversible capacity of around 1270 mAh g(-1) due to its faster kinetics and structural similarity between cycled and pristine states. These findings suggest that polymorphs are an important factor in designing high-performance materials for next-generation rechargeable batteries.

Summary: This study found that the overexpression of miRNA-152 in pulmonary artery endothelial cells (HPAECs) is associated with endothelial dysfunction. A nucleic acid nanostructure called DNT-152 was constructed and efficiently taken up by HPAECs, leading to apoptosis and inhibition of HPAEC growth under hypoxic conditions. Mechanistically, DNT-152 silenced miRNA-152 expression and upregulated its target gene Meox2, thereby inhibiting the AKT/mTOR signaling pathway. These findings suggest that miRNA-152 in HPAECs could be a potential therapeutic target for pulmonary vascular remodeling, and carefully designed framework nucleic acids hold promise as nanomedicines for noncancerous cells and diseases.
