Summary: This paper investigates excitation-dependent energy dissipation during friction between graphene layers in both commensurate and incommensurate states. The results reveal that when the excitation frequency of the tip matches its natural frequency, friction resonance occurs, leading to system breakdown. The origin of this friction resonance is systematically revealed through fast Fourier transform analysis. Additionally, the influence of temperature on frictional energy dissipation differs in commensurate and incommensurate cases due to the net effect of thermal lubrication and thermal collision. Finally, the phononic mechanism of frictional energy dissipation is quantitatively analyzed by calculating the phonon number in different contact states.

Summary: Investigation on the B20-type cobalt germanide compound CoGe was conducted by measuring specific heat, resistivity, and Co-59 nuclear magnetic resonance (NMR). A phase transition at 13.7 K, along with a crossover scale T-0 and the quadrupole-order-driven commensurate-incommensurate phase transition, were observed in this study. The study suggests that the T-Q transition in CoGe may be driven by a finite electric quadrupole density arising from the low local site symmetry at cobalt sites.

Summary: The photonic moire patterns created by two mutually twisted periodic sublattices in quadratic nonlinear media can allow the formation of parametric solitons, with the geometry of the pattern significantly impacting the conditions for soliton excitation and the properties of soliton families. The geometry also broadens the phase-mismatch bandwidth for soliton generation compared to latticeless structures.

Summary: Magnetic susceptibility, specific heat, and neutron powder diffraction measurements were performed on polycrystalline Li2Co(WO4)(2) samples. Two successive magnetic transitions were observed under zero magnetic field, with the magnetic ordering temperatures decreasing as the magnetic field increases. Neutron diffraction revealed an incommensurate magnetic state in Li2Co(WO4)(2) with a temperature dependent magnetic propagation vector. Below a certain temperature, the magnetic propagation vector locked into a commensurate value. The antiferromagnetic structure was determined at 1.7 K with a magnetic moment of 2.8(1) mu (B), consistent with first-principles calculations.

Summary: The study reveals unprecedented commensurate and incommensurate charge ordered phases in the simple transition-metal mono-oxide CoO at room temperature, with periodic lattice distortions characterized by electron diffraction patterns and transmission electron microscopy. Density functional theory calculations elucidate the mechanism of introducing mixed valence states through cation disordering, leading to the stabilization of Jahn-Teller distortion and localized Co3+ states in CoO. This offers an electronic paradigm for engineering charge ordering and exploiting associated functionalities in transition-metal mono-oxides.

Summary: We investigated the occurrence of multiple friction peaks with increasing velocity in commensurate and incommensurate states between graphene layers. Fast Fourier transform analysis revealed that the frictional spectrum mainly distributed at the washboard frequency of the tip and its harmonics. Resonance occurred in both contact cases when the washboard frequency approached the natural frequency of the tip and its fractional frequencies, resulting in friction peaks. Phonon spectra of the tip and substrate matched in the commensurate state, establishing effective energy dissipation channels, but did not match in the incommensurate state. We also proposed a theoretical model to calculate the number of excited phonons and quantitatively explain the friction discrepancy in different contact states and velocities.

Summary: In this paper, an atomistic method is used to investigate the electronic structures of twisted trilayer graphene (TTG) with two independent twist angles. The lattice relaxation, twist angle, and angle disorder effects on the van Hove singularities (VHSs) are discussed, and it is found that lattice relaxation significantly influences the position and magnitude of the VHSs. The moire interference in the supermoire TTG can lead to the formation of various commensurate/incommensurate complex supermoire patterns, and a slight change in twist angles can suppress the peak of the VHSs.

Summary: Dense systems of magnetic nanoparticles can exhibit collective behavior, and it remains unclear whether the transition temperature is influenced by particle anisotropy or determined by interparticle dipolar interactions. Additionally, the minimum ratio of dipole-dipole interaction to nanoparticle anisotropy energies necessary for the crossover from individual to collective behavior is unknown. This study investigates particle assemblies with varying anisotropy and finds a threshold value to suppress collective behavior. The findings have practical applications in predicting the behavior of interacting particle assemblies.

Summary: The development of aqueous zinc-ion batteries (AZIBs) with high capacity and cycling stability is of great interest. In this study, a novel modification technology is developed by spraying a Ketjen black (KB) conductive carbon layer on the side of the cathode, resulting in improved capacity and cycle stability of AZIBs. The KB separator reduces charge transfer impedance and improves ion diffusion coefficient, contributing to excellent electro-chemical kinetics. Additionally, the unique adsorption properties of the KB separator reduce attachment of by-products on the cathode surface and electro-oxidize Mn2+ ions to generate electrochemically active layered birnessite, leading to stable electrochemical performance and improved battery capacity.

Summary: Hepatocellular carcinoma (HCC) is a highly deadly tumor with a significant rate of recurrence and metastasis. Cancer stem cells (CSCs) play a crucial role in these processes, providing a new perspective on liver cancer development. A study utilized composite magnetic nanocubes modified with polyethyleneimine (PEI) and hyaluronic acid (HA) to target HCC stem cells. The nanocubes successfully recognized the stem cells through receptor-ligand binding. The study also showed that the nanocubes inhibited HCC cell proliferation and migration by regulating the expression of epithelial-mesenchymal transition (EMT) markers.

Summary: This study reveals that CCL18 secreted by TAMs activates a CD10(+)GPR77(+) CAF phenotype in NBFs, leading to the enrichment of CSCs and chemoresistance in breast cancer cells. Mechanistically, CCL18 activates NF-kappa B signaling via PITPNM3 and enhances IL-6 and IL-8 production. Targeting CCL18 with anti-CCL18 antibody inhibits the formation of CD10(+)GPR77(+) CAFs and restores chemosensitivity, effectively controlling tumors.

Summary: This article proposes a fixed-time backstepping distributed cooperative containment control scheme for multiple unmanned aerial vehicles (UAVs). It solves the actuator saturation problem of fixed-wing UAVs with a fixed-time compensator. An improved fixed-time disturbance observer is proposed to address the excessive initial peak problem. The fixed-time differential filter solves the complexity explosion problem. For the distributed containment control of multiple UAVs, a cooperative control architecture based on a fixed-time anti-saturation compensation system is proposed. Simulation results demonstrate the effectiveness of the proposed control scheme.

Summary: The introduction of suitable passivation materials has significantly improved the power conversion efficiency (PCE) of perovskite solar cells (PSCs) in recent years. Using machine learning (ML), this study investigates the relationship between the molecular fingerprints of passivation materials and the PCE of p-i-n type PSCs. Nitrogen atoms and acryloyl groups in the passivation material are found to have the most influence on the PCE of p-i-n type PSCs. A non-fullerene material, ITIC, which contains both nitrogen atoms and acryloyl groups, is selected to passivate perovskite defects. Treatment with ITIC enhances charge transport, diminishes the defect density, improves crystallinity, and reduces surface roughness of the perovskite films. Density-functional theory (DFT) calculations validate the effective passivation of uncoordinated Pb2+ ions by incorporating ITIC. The PCE of the ITIC-treated PSC shows a 20.97% enhancement compared to a non-treated PSC. In conclusion, ML has great potential in selecting effective passivation materials for PSCs.
