Summary: This paper investigates the preparation of polystyrene nanosphere monolayers for the fabrication of carbon nanotube fishnet metamaterial structures. Precise control of dry etching conditions enables highly controlled diameter of polystyrene nanobeads, which are used as shadow masks for carbon nanotube preparation. Changing the hole size results in the morphological and resonant frequency variation of carbon nanotube fishnets. This study has significant potential for large-scale fabrication of carbon nanotube-based fishnet metamaterial structures, with applications in energy harvesting, energy storage, solar cells, and optoelectronic devices such as neuromorphic networks.

Summary: In this study, trions have been successfully confined in a one-dimensional restricted space of a MoSe2 device using carbon nanotube (CNT) gate electrodes. The dry transfer process, including deterministic dry transfer of aligned CNTs, has resulted in an hBN-encapsulated MoSe2 device with CNT back gate electrodes. Applying voltage via CNT gate electrodes significantly alters the PL spectra at the location with CNT gate electrodes, which is not observed at a location without CNT gate electrodes. PL imaging shows that the image contrast from trions along the CNT electrode underneath is linear, indicating the one-dimensional confinement of trions in response to the CNT local gating. The obtained confinement width from the PL image is 5.5 x 10(2) nm, consistent with nanoscale one-dimensional confined trions with diffraction limit broadening. This work demonstrates the electrical control of excitonic states at the nanoscale, leading to potential novel optoelectronic properties and exciton devices in the future.

Summary: Composite structural supercapacitors (SSC) were manufactured using aerospace-grade composite materials and CNT mat electrodes. A new design methodology was explored where the supercapacitor electrolyte was localized within the composite structure, achieving good electrochemical performance within the active region, whilst maintaining excellent mechanical performance elsewhere. The morphology of these localized SSC designs was characterized and found to be directly correlated with both electrochemical and mechanical performance. One configuration using an ionogel with an ionic liquid electrolyte achieved high energy density and corresponding short beam shear strength, while another configuration with only an ionic liquid electrolyte also achieved high energy density and shear strength. Both configurations provide a combined energy and strength superior to previous results in the literature for composite SSCs.

Summary: This study focuses on the manipulation of collagen self-assembly in vitro, revealing its significant impact on the mechanical response of biological tissues. The involvement of suprafibrillar organization is crucial for modulus at early stage of deformations and tensile toughness, while mechanisms at the fibril level affect durability under cyclic loading and stress relaxation. By altering interfibrillar interactions through changes in physicochemical environment, more biomimetic mechanical responses can be achieved, offering new possibilities for tissue engineering.

Summary: Circulating tumor cells (CTCs) have potential as biomarkers for diagnosing, predicting and monitoring cancer, but their diagnostic utility is yet to be proven. The scarcity of CTCs in biological fluids makes it difficult to identify dangerous subpopulations that could lead to metastasis. This Perspective discusses promising techniques for identifying metastatic cells, including isolating patient-derived CTCs, using 3D biomimetic matrixes for their analysis, and analyzing CTCs at the single-cell and single-molecule levels. The article also explores the combination of mechanical and morphological analysis methods with biomarker identification techniques for more accurate diagnosis.

Summary: This study demonstrates the improvement of mechanical properties and reduction of coefficient of thermal expansion (CTE) in graphene oxide (GO)/epoxy (EP) nanocomposites by enhancing the interface between GO and EP through functionalization and incorporating rigid-flexible interphases. The results reveal that the SiO2-PEA-GO hybrid exhibits better strengthening and toughening effects, as well as lower CTE, compared to the PEA-GO hybrid due to the presence of rigid-flexible interfaces with higher bonding strength and better energy dissipation mechanisms. Additionally, the nanocomposites with longer polyetheramine (PEA) molecules in the rigid-flexible interphases demonstrate higher strength and toughness, while maintaining a lower CTE. This work provides a promising strategy for constructing adjustable flexible-rigid interfacial structures and offers potential in developing GO/EP nanocomposites with high mechanical properties and low CTE.
