Summary: The preparation of monolayers based on an organic radical and its diamagnetic counterpart has been investigated on hydrogen-terminated silicon surfaces. The monolayers exhibit a characteristic diode behavior in solid-state metal/monolayer/semiconductor junctions, which is influenced by the electronic characteristics of the organic molecule. The presence of the radical significantly enhances the rectification ratio and photosensitivity of the junction.

Summary: The functionalization of cellulose nanocrystal aerogels with aminosilane via vapor-phase reaction resulted in similar amine loading but different crystallinity and thermal stability. The modified CNC-FD aerogel exhibited lower crystallinity and thermal stability compared to the modified CNC-SC aerogel, indicating that the modification process has an impact on the properties of the aerogels.

Summary: ALD metal oxide layers were surface modified with vapor-phase (3-aminopropyl)triethoxysilane (APTES) at different temperatures, showing uniform monolayer silane formation through various measurement techniques. Higher surface density of grafted APTES species was observed at lower temperature due to temperature-dependent reactivity of the surface hydroxyls. APTES reacted with Al2O3 and ZnO exclusively through metal siloxy bond formation, while with TiO2 through both siloxy bond formation and ammonium salt formation.

Summary: This article reports the synthesis of two-dimensional SiC and its stability on transition metal carbides. It was found that 2D-SiC is stable at high temperatures and interacts with the surface of transition metal carbides to produce a Dirac-like feature in the electronic band structure. This finding is significant for the synthesis and application of 2D-SiC.

Summary: Sub-monolayer superstructures of Eu atoms self-assembled on the silicon surface exhibit strong magnetic signals, revealing robust easy-plane magnetism in both one- and two-dimensionally ordered structures. This emergence of 2D magnetism shows a strong dependence of the effective transition temperature on weak magnetic fields, providing a versatile platform for miniaturization of 2D magnetic systems for applications in information technologies.

Summary: The surface functionalization of two-dimensional (2D) material MoS2 with organic electron donors (OEDs) has been successfully achieved using the novel molecular dopant Me-OED, which demonstrates record-breaking molecular doping with significantly higher carrier density compared to other OEDs. The impressive doping power of Me-OED is attributed to its compact size, enabling high surface coverage and molecular interactions with MoS2.

Summary: The first syntheses of functionalized sila-adamantanes via site-selective reactions are described. Mechanistic inquiry into the isomerization of sila-adamantane revealed new approaches for installing halides at the 2-position of the cluster. Optical absorbance and density functional theory studies show that sigma-withdrawing substituents at the 1-position strongly perturb optical absorbance in sila-adamantane.

Summary: Three organic monolayers coatings were developed and tested to improve the cleaning efficiency of microscale particles attached to surfaces by air flows. The coatings did not affect the laser-induced-damage threshold values and exhibited significantly improved cleaning efficiency with a gas flow. Larger particles (> 5 μm) were removed from the coated substrates with almost 100% efficiency, while the coatings improved the cleaning efficiency of smaller particles (≤ 5 μm) by 17% to 30% for stainless steel and 19% to 38% for silica particles.

Summary: A method to dope monolayer CVD graphene with nitrogen and induce ferromagnetism was demonstrated, showing a coercivity of 222 Oe at low temperatures. Changes in the angle of the applied magnetic field affected the anisotropic magnetoresistance effect in the doped graphene devices, with varying AMR values at different temperatures. The introduction of magnetism in CVD graphene after nitrogen doping was confirmed through magnetic force microscopy and electron spin resonance spectroscopy, suggesting potential applications in spintronics.

Summary: The structure and stability of monolayer Sr2S was studied using first principles calculations. The impact of termination states with F, O, and OH on the electronic properties of pure Sr2S in three different configurations was investigated. The pure Sr2S structure was found to be physically stable and a non-magnetic metal. The response of monolayer Sr2S to fluoride, oxide, and hydroxide varied for each configuration. The terminated pure monolayer Sr2S proved to be a promising material for nanoelectronics and spintronic industries.

Summary: As a promising approach in translational medicine, the decellularization of discarded livers to produce bioscaffolds that support recellularization has potential in overcoming the limitations of conventional liver transplantation. In this study, the researchers investigated the use of matrix metalloproteinase (MMP) inhibition to preserve the extracellular matrix (ECM) during liver decellularization. The results demonstrated that the application of an MMP inhibitor significantly improved the preservation of ECM components and mechanical properties of the bioscaffolds, which supported cell viability and function in vitro. The study also confirmed that the MMP inhibition led to the inhibition of MMP2 and MMP9, providing a novel method to enhance ECM preservation during liver decellularization.

Summary: Human skin equivalents (HSEs) play a crucial role in tissue engineering. This study introduces a 3D-printed culture insert to apply a static radial constraint on HSEs and examines its effects on tissue characteristics. The results show that the diameter of the culture insert significantly influences tissue contraction, fibroblast and matrix organization, keratinocyte differentiation, epidermal stratification, and basement membrane formation. This study provides important insights for the design of skin tissue engineering.

Summary: This paper reviewed the primary methods for improving the overall properties of biodegradable zinc stents. It discussed the mechanical properties, degradation behavior, and biocompatibility of various improvement strategies. Alloying was found to be the most common, simple, and effective method for improving mechanical properties. Deformation processing and surface modification further improved the mechanical properties and biological activity of zinc alloys. Meanwhile, structural design could endow stents with special properties. Manufacturing zinc alloys with excellent properties and exploring their interaction mechanism with the human body are areas for future research.
