Summary: The study found that tree-shaped fractal patterns could be self-assembled from Fmoc-Glu and ZnTPyP, composed of nanorod aggregate arranged in a spiral fractal way. The formation and growth of initial nucleon led to the fractal patterns, and the spiral packing and their branches were closely related to the absolute configuration of Fmoc-Glu.

Summary: This study proposes a droplet-confined, magnetic-induced self-assembly strategy for generating rotary structural color spindles (SCSPs) by fast solvent extraction. The as-prepared SCSPs exhibit an orderly close-packed lattice structure, thus appearing brilliant structural colors that serve as encoding tags for multiplexed bioassays. Based on these merits, a portable point-of-care-testing strip integrating the rotary SCSPs is further constructed and the capability and advantages of this platform for multiplexed detection of tumor-related exosomes in clinical samples are demonstrated.

Summary: This study investigates the properties of droplet deposition and splitting dynamics on patterned surfaces through experimental visualization and numerical simulations. The research finds that droplets can be successfully split using hydrophobic/hydrophilic patterned surfaces, and the splitting, satelliting, and splashing modes of the droplets are influenced by the surface pattern geometry. The derived energy conservation model confirms the experimental and numerical findings that droplet deposition dynamics are determined by fluid properties and surface wetting characteristics.

Summary: In this study, an ordered aligned halloysite nanotube (HNT) architecture on a glass substrate was successfully fabricated by drying the aqueous dispersion of HNTs with the assistance of a magnetic rotor. The perfectly ordered alignment of nanotubes was achieved when the HNT concentration was above 5 wt %. Furthermore, the fabricated HNT pattern also promoted the adhesion and proliferation of mouse fibroblast cells.

Summary: The heterogeneous self-assembly of a single type of nanoparticle is achieved by quickly evaporating a colloid-poly(ethylene glycol) (PEG) droplet, facilitated by the spatial confinement induced by a skin layer. This approach allows for the formation of face-centered-cubic (FCC) lattices with different plane orientations, generating binary bandgaps and structural colors. The self-assembly of nanoparticles can be regulated by adjusting the PEG concentration, and the method is applicable to various droplet shapes, substrates, and nanoparticle types.

Summary: Reproductive interactions among closely related plant species through pollination may play a significant role in community assembly and co-occurrence. Outcrossing congeners are more likely to co-occur in sites lacking congeners, while selfers tend to be more common in communities with multiple congeners. Flower size and reliance on outcrossing were found to be key factors influencing co-occurrence patterns among Trifolium species.

Summary: In this paper, the dynamic mechanism of controllable single-walled carbon nanotubes (SWCNTs) arrays prepared by self-assembly method is studied through a combination of experiments and simulations. Key factors such as the self-assembly template and the concentration of the SWCNTs dispersion are investigated and optimized, leading to improved fidelity of the array pattern and distribution morphology of individual SWCNTs. The application of a blade-coating procedure in the self-assembly process enhances the alignment of SWCNTs in the array.

Summary: Bioinspired, highly flexible, fast, and biodegradable heaters were fabricated using Ag nanowires and leaf skeletons of different plant species. The leaf skeletons act as transparent substrates, allowing a uniform dispersion of the Ag nanowires, leading to excellent transmittance and flexibility properties. The performance of the bioinspired heater surface is dependent on the types of fractal structures at the microscale. Insights for the fabrication of heaters suitable for practical wearable, medical, or industrial heating applications are provided based on the study.

Summary: This study aimed to evaluate the clinical characteristics and prognosis of patients with left ventricular thrombus (LVT). The results showed that atrial fibrillation, renal dysfunction, and left ventricular ejection fraction (LVEF) <= 50% were independent risk factors for major adverse cardiovascular events (MACE), while age, previous coronary artery bypass grafting (CABG), LVEF <= 50%, and large thrombus area were independent risk factors for all-cause mortality. The use of beta-blockers was found to improve the prognosis of patients with LVT. It is recommended that clinicians should consider using anticoagulants for LVT patients.

Summary: We report a high-sensitivity multimodal force-sensing transparent droplet probe for characterizing superhydrophobic surfaces, allowing simultaneous visualization of the wetting interface and measurement of interaction forces. The probe consists of a transparent glass cantilever with a droplet probe attached, which directly images the wetting interface and measures forces simultaneously. By combining top view, side view, and high-resolution force sensing, the probe can reveal force contributions from both surface tension and Laplace pressure and measure super-repellent surfaces with contact angles near 180 degrees with a low experimental uncertainty of 0.5 degrees.

Summary: Acoustic manipulation is a technique that uses sound waves to move particles, droplets, or cells. A new adaptive control method is proposed in this article, based on online machine learning of the acoustic fields. The controller can manipulate particles even on the first attempt and improve its performance through subsequent attempts, while still being able to readapt to sudden changes in system parameters. The online adaptiveness of the controller makes it easier to use in practical applications without extensive training or prior models.

Summary: Many natural and artificial water-repellent surfaces have micro- and nano-roughness and their wetting properties can be determined by observing the contact angles at the liquid-solid interface. However, a generally applicable method to directly observe the moving contact lines on such surfaces is missing. In this study, we demonstrate that a transparent droplet probe combined with a conventional optical microscope can accurately quantify the contact angles and contact area on water-repellent surfaces.

Summary: We study the CDF W-mass, muon g-2, and dark matter observables in a local U(1)L-mu-L-tau model. We find that the CDF W-mass is related to the mixing parameter of left (right)-handed fields of vector-like leptons and favors a large mass splitting between them when the differences between mixing parameters become small. The correct dark matter relic density is mainly obtained in two scenarios, one involving the annihilation of X-I X-I into Z' Z' and SS, and the other involving co-annihilation processes.
