However, a critical bottleneck in clinical application has been the lack of mRNA delivery vehicles that can efficiently transfect cells in the brain. In this report, we demonstrate that in utero intracerebroventricular (ICV) injection of densely PEGylated lipid nanoparticles (ADP-LNPs) containing an acid-degradable PEG–lipid can safely and effectively deliver mRNA for gene editing enzymes to the fetal mouse brain, resulting in successful transfection and editing of brain cells. ADP-LNPs containing Cre mRNA transfected 30% of the fetal brain cells in Ai9 mice and had no detectable adverse effects on fetal development and postnatal growth. In addition, ADP-LNPs efficiently transfected neural stem and progenitor cells in Ai9 mice with Cre mRNA, which subsequently proliferated and caused over 40% of the cortical neurons and 60% of the hippocampal neurons to be edited in treated mice 10 weeks after birth. Furthermore, using Angelman syndrome, a paradigmatic neurodevelopmental disorder, as a disease model, we demonstrate that ADP-LNPs carrying Cas9 mRNA and gRNA induced indels in 21% of brain cells within 7 days postpartum, underscoring the precision and potential of this approach.

The addition of a plasticizer into polymer electrolytes could significantly promote ion transport while inevitably decreasing their mechanical strength. Herein, we report a supramolecular plasticizer (SMP) to break the trade-off effect between ionic conductivity and mechanical properties in PEO-based polymer electrolytes. Accordingly, the SMP is constructed by tetraethylene glycol dimethyl ether (G4) and SbF₃ through halogen bonds. The SMP-plasticized PEO electrolyte (PEO/SMP) presents a simultaneously enhanced ionic conductivity of 2.4 × 10^–4 S cm^–1 (25 °C) and a high mechanical strength of 8.1 MPa, compared to those of pristine PEO-based electrolytes. Benefiting from the halogen bonds between G4 and SbF₃, the Li–O coordination in PEO/SMP is evidently weakened, and thus rapid Li⁺ transport is achieved. Furthermore, the PEO/SMP electrolyte possesses a wide electrochemical stability window of 4.5 V and, importantly, derives an inorganic-rich SEI with a low interfacial resistance on a lithium metal surface. By using PEO/SMP, the lithium-metal battery with the LiNi_0.5Co_0.2Mn_0.3O₂ cathode exhibits a good rate and long-term cycling performance with a capacity retention of 75.3% (500 cycles).

Herein, we delve into the behavior of strained bilayer molybdenum disulfide (2L-MoS₂) transferred onto a nanocone-patterned substrate. An intriguing observation is the emergence of unexpected vertical ferroelectricity in MoS₂, irrespective of whether it was prepared using chemical vapor deposition or mechanical exfoliation from the bulk crystal. Such an observation underscores the versatility and reproducibility of the emerging ferroelectricity across different preparation methods. Furthermore, the piezoelectric coefficients recorded are exceptionally high, with the values of 37.54 and 24.80 pm V^–1 for monolayer and bilayer MoS₂, respectively, outperforming most currently discovered 2D piezoelectrics. The presence of room-temperature out-of-plane ferroelectricity in strained 2L-MoS₂ is confirmed through first-principles calculations and piezoresponse force microscopy. This ferroelectric behavior can be attributed to the symmetry breaking and interlayer sliding within the strained 2L-MoS₂ structure.

By systematically optimizing the thickness of the crystalline In₂O₃ (c-In₂O₃) layer to create a narrow quantum well, we observed a significant increase in saturation mobility (μ_SAT) from 12.76 to 97.37 cm² V^–1 s^–1. This enhancement, attributed to quantum confinement, was achieved through the deposition of a 3 nm c-In₂O₃ semiconductor via spray pyrolysis. Various In₂O₃ layer thicknesses (2–5 nm) were obtained by adjusting precursor solution concentration, flow rate, and number of spray cycles. Post annealing treatments were employed to reduce the defects at the interface and within the oxide film, enhancing device stability and performance. Transmission electron microscopy (TEM) confirmed the uniformity of the c-In₂O₃ film thickness, while variations in thickness significantly influenced TFT performance, particularly the turn-on voltage (<i>V</i>_GS) due to changes in the carrier concentration. Ultraviolet photoelectron spectroscopy (UPS) and X-ray photoelectron spectroscopy (XPS) supported the formation of a potential well with a two-dimensional electron gas (2DEG). The study of single and multiple superlattice structures of consecutive c-In₂O₃ and c-ZnO layers provided insights into the effects of multiple quantum wells on the TFT performance.
