Summary: This study reveals the importance of vapor catalysis in superclean graphene growth through density functional theory calculations, an ideal gas model, and a designed experiment. The study finds that the vapor mainly consists of Cui clusters, which have a significant impact on graphene growth. DFT calculations show that Cu clusters exhibit strong capabilities for adsorption, dehydrogenation, and decomposition, providing a sufficient supply of active carbon atoms for rapid graphene growth. Experimental validation confirms that increasing the amount of Cu vapor improves the growth rate and surface cleanliness of graphene.

Summary: As the current top-down microchip manufacturing processes approach their resolution limits, alternative patterning technologies with high feature densities and nanometer resolution are needed. This study investigates the impact of thermodynamic processes on the area selectivity of chemical vapor deposition (CVD) polymerization of functional [2.2]paracyclophanes (PCP). Adhesion mapping by atomic force microscopy (AFM) reveals the geometric features of polymer islands formed under different deposition conditions. A kinetic model is developed to predict area-selective and nonselective CVD parameters for the same polymer/substrate ensemble (PPX-C + Cu), highlighting the potential for thermodynamic control in tuning area selectivity.

Summary: Synergistic additives, ammonium salts, have been used in the chemical vapor deposition (CVD) growth of MoS2 to achieve controlled domain layering and shape, as well as centimeter-scale films. This method enables direct fabrication of MoS2 electronic devices on clean substrates without the need for transfer steps, and it also promotes improved hydrogen evolution reaction (HER) performance. The use of ammonium salts in CVD paves the way for practical applications of MoS2 in modern electronics and catalysis.

Summary: Ureilite meteorites, which may be the only samples from a dwarf planet's mantle, contain abundant diamonds. Electron microscopy reveals the distribution of lonsdaleite, diamond, and graphite in ureilites, suggesting a formation process involving pseudomorphic replacement of graphite by lonsdaleite, followed by diamond and graphite formation. This process could be used to manufacture shaped lonsdaleite at high pressure and also provides a model that reconciles conflicting observations about diamond formation in ureilites.

Summary: In patients with limited-stage small-cell lung cancer, a high dose of twice-daily thoracic radiotherapy (TRT) combined with concurrent chemotherapy using the simultaneous integrated boost IMRT (SIB-IMRT) approach may improve progression-free survival (PFS) without increasing toxicities. However, this improvement in PFS did not result in significant advantages in overall survival (OS).

The results showed that age, T stage, ulcerative esophageal cancer, and the maximum thickness of the tumor were correlated with the prevalence of EF. These risk factors should be highly concerned in clinical work, and individualized treatment plans should be implemented to reduce the occurrence of EF.

Summary: Prenatal alcohol exposure has negative effects on brain development and increases the risk of poor mental health. This study found that susceptibility in the nucleus accumbens was negatively associated with internalizing problems, while amygdala susceptibility was positively associated with internalizing problems. Prenatal alcohol exposure moderated the relationships between thalamus and putamen susceptibility and internalizing and externalizing symptoms. Brain volume was not related to internalizing or externalizing symptoms.

Summary: Over 50% of individuals with esophageal cancer present with advanced stages of the disease, resulting in poor outcome following surgery alone. Neoadjuvant chemoradiotherapy has become the standard therapy for locally advanced esophageal cancer based on clinical trials. However, there are still controversies and questions regarding the optimal treatment approach. Combination therapy with immune checkpoint inhibitors is also being explored.

Summary: Deep neural networks show great potential in solving dipole inversion for QSM. However, they perform poorly when there are mismatched sequence parameters. In this study, we propose the AFTER-QSM deep neural network, which is robust against arbitrary acquisition orientation and spatial resolution. The network achieves excellent generalizability and significantly improves image quality assessments and reduces artifacts and noise levels compared to other methods.

This study uses remote sensing and ground observation data to assess the impact of O-3 on China's NPP. The findings show a significant negative correlation between NPP and O-3 concentration in farmland and grassland ecosystems. The estimated percentage of O-3-induced NPP decline ranges from 5% to 35%, with the highest declines in farmland ecosystems.

Summary: Thin film polyethylene oxide, produced by the thermal evaporation technique, exhibits structural and property differences compared to bulk polyethylene oxide. The dielectric constant of polyethylene oxide thin film is 10 times greater than that of bulk polyethylene oxide. There is consistency among dielectric constants, activation energies, and free volume fractions for both thin film and bulk samples. Polyethylene oxide thin film is observed to be more brittle than bulk polyethylene oxide.

Summary: Although molecular dynamics (MD) simulation is a powerful tool for investigating the atomic-scale structures of complex materials, its reliable and accurate application to multi-component glass systems faces challenges due to limited force fields (FFs) and the complexity of chemical environments. This study demonstrates the feasibility of efficient and accurate large-scale density functional theory (DFT) calculations for multi-component glass systems. The evaluation of classical FFs based on the results of large-scale DFT calculations reveals low accuracy for non-bridging oxygen atoms, and differences in Si-O-Si angle distribution and electronic structure for X = Mg.

Summary: In this study, vanadium oxide xerogel samples were successfully synthesized through a liquid phase reaction and the interaction of films with water. The samples were thoroughly analyzed using X-ray diffraction and Raman spectroscopy, revealing the existence of two distinct phases. It was also discovered that previous misinterpretations regarding the high-pressure polymorph structure were due to the formation of a high-temperature phase. These findings highlight the potential for further refining and expanding the current structural models of vanadium oxide xerogel in future research efforts.
