Summary: Microbial communities that degrade natural polysaccharides were previously believed to have a hierarchical organization with one-way positive interactions from higher to lower trophic levels. However, recent research by Daniels et al. shows that reciprocal interactions between trophic levels can occur and that these interactions change over time in batch cultures.

Summary: Complex coacervate microdroplets derived from associative phase separation have shown great potential in constructing membraneless protocells. However, the lack of an enclosing membrane limits their functionality. In this Account, we present chemical strategies for the membranization of coacervate microdroplets and discuss their potential applications as functional materials. We hope that this Account will inspire further research and development in this field.

Summary: This study reports the growth of nanostructured tungsten oxide (WO3) thin film on SiO2 substrate under controlled oxidation conditions for NO sensing. The fabricated sensor demonstrates high selectivity, stability, and faster response/recovery time, with an ultra-high response for 1 ppm NO concentration at 250 degrees C. The ultra-high response is attributed to the high specific surface area and effective gas diffusion ability of the sensor.

Summary: A novel nanoplatform was developed for efficient NO production based on ultrasound-induced piezocatalysis. The nanoplatform was fabricated by coating amphiphilic poly-L-arginine (DSPE-PEG2000-Arg, DPA) on the piezoelectric material of barium titanate (BTO). The resulting BTO@DPA nanoparticles can generate H2O2, 1O2, and O2 via ultrasound-induced piezocatalysis based on BTO, and oxidize surface arginine to produce NO, inducing tumor cell apoptosis in hypoxia and normoxia.

Summary: We find a self-similar prethermal dynamical regime in the time evolution of one-dimensional spin chains when quenching near a quantum phase transition. This regime is analytically determined by the ground-state energy gap and exists universally regardless of the probe site, weak interactions, or the initial state. The resulting prethermal dynamics result in an out-of-equilibrium scaling function of the order parameter near the transition. Our theory suggests that sudden quench dynamics can lead to universal critical slowing down near the critical point.

Summary: Lithium metal anodes have great potential for high-energy-density secondary batteries. However, uncontrolled lithium dendrite growth inhibits their practical application. This study proposes an interfacial high-concentration electrolyte induced by nitrogen- and oxygen-doped carbon nanosheets (NO-CNS) to stabilize lithium metal anodes. The interfacial high-concentration electrolyte improves charge transfer kinetics and ionic mass-transfer, leading to excellent electrochemical performance.

Summary: To stabilize sodium metal anodes (SMAs), various strategies have been developed, including employing anode hosts and electrolyte additives to establish protective layers. In this study, the interaction mechanism between sodium metal and sulfur-containing functional groups was investigated using comparative model systems of alpha-sexithiophene (6T) and p-sexiphenyl (6P). The results showed that sodium atoms tend to interact with sulfur atoms and their connected carbon atoms as well as the aromatic carbon atoms of the end groups of 6T molecules, while no chemical interaction between Na and 6P molecules was observed. These findings shed light on the rational design of sulfur-containing protective materials and relevant interface engineering to stabilize SMAs.

Summary: Realizing effective Ohmic contact to SiC is a major challenge in high-power and high-frequency SiC electronics. Here, we grew a high-work-function interfacial molybdenum trioxide (MoO3) layer on 4H-SiC(0001) and investigated its surface properties during annealing in different gas environments. The results show that the MoO3 layer tends to be reduced and the surface work function decreases accordingly, making it a promising approach for achieving effective Ohmic contact with SiC.

Summary: In this study, the growth mechanism and interfacial chemistry of ultrathin platinum and molybdenum films on high-crystalline Al1-xScxN surface were investigated. The chemical and electronic structure evolution of the interface during the deposition process were examined using in-situ X-ray photoelectron spectroscopy and ultraviolet photoelectron spectroscopy. The structural properties of the interface were characterized by cross-sectional transmission electron microscopy, X-ray diffraction spectroscopy, and atomic force microscopy. The study reveals the formation of ionic Pt2+-N bonds at the Pt/Al1-xScxN interface, while molybdenum does not bond with the substrate. Furthermore, electron transfer induces upward band-bending effects on the Al1-xScxN surface upon both platinum and molybdenum interactions. The research on the chemical and structural properties of ultrathin metal electrodes and Al1-xScxN interfaces provides guidance for designing high-performance micro-electromechanical devices.

Summary: We report the phase-controlled growth of ternary monolayer MoSe2xTe2(1-x) alloys induced through in situ doping and composition tuning. The lattice constants, Mo-3d binding energy, and electronic bandgap of the alloys can be tuned by varying the selenium composition. First-principles calculations reveal that the valence band bowing effect of the monolayer alloys is attributed to the difference in coupling between anions and cations. This work provides a new pathway for phase modulation growth and controllable electronic structure of ternary monolayer transition metal dichalcogenide alloys.
