Frank-Kasper (F-K) and quasicrystal phases were originally identified in metal alloys only sporadically reported soft materials. These unconventional sphere-packing schemes open up possibilities to design materials with different properties. The challenge is how correlate complex built from spheres the tunable parameters of chemical composition molecular architecture. Here, we report a complete sequence various highly ordered mesophases by self-assembly specifically designed synthesized...
As emerging pollutants in the environment, nanoplastics (NPs) can cross biological barriers and be enriched organisms, posing a greatest threat to health of livestock humans. However, size-dependent toxic effects NPs higher mammals remain largely unknown. To determine potential toxicities NPs, we exposed mouse (AML-12) human (L02) liver cell lines vitro, 6-week-old C57BL/6 mice (well-known preclinical model) vivo five different sizes polystyrene (PS-NPs) (20, 50, 100, 200 500 nm). We found...
Abstract Strain sensors utilizing mechanoluminescent (ML) materials have garnered significant attention and application due to their advantages, such as self‐powering, non‐contact operation, real‐time response. However, ML‐based strain sensing techniques typically rely on the establishing of a mathematical relationship between ML intensity mechanical parameters. The absolute is vulnerable environmental factors, which can result in measurement errors. Herein, an color‐resolved visualized...
Abstract Uncontrolled and excessive photothermal heating in therapy (PTT) inevitably causes thermal damage to surrounding normal tissues, severely limiting the universality safety of PTT. To address this issue, an intelligent cooling thermal‐responsive (ICTR) gel containing poly(N‐isopropylacrylamide‐co‐acrylamide) (P(NIPAM‐AM))microgel is applied onto skin realize PTT, which can avoid accidental injury. The high near‐infrared (NIR) light transmittance (> 95%) ICTR ensures effective...
The recent Mamba model has shown remarkable adaptability for visual representation learning, including in medical imaging tasks. This study introduces MambaMIR, a Mamba-based image reconstruction, as well its Generative Adversarial Network-based variant, MambaMIR-GAN. Our proposed MambaMIR inherits several advantages, such linear complexity, global receptive fields, and dynamic weights, from the original model. innovated arbitrary-mask mechanism effectively adapt to our reconstruction task,...
The bottom-up construction of Frank–Kasper (FK) phases in soft matter requires intricating tuning to balance entropic and enthalpic interactions. In contrast, sophisticated rules have been established Metallurgy dictate the packing structures metal alloys. Inspired by alloy metallurgy, we develop a new self-sorting approach construct nanostructures condensed matters. This utilizes blends nano-sized giant molecules supramolecular motifs ("mesoatoms") with controlled size heterogeneity, which...
This work reports the molecular design, synthesis, and systematic study on bulk self-assembly behaviors of three series polyhedral oligomeric silsesquioxane (POSS)-based multiheaded giant surfactants XDPOSS-PSn (X = 2, 3, 4), which are composed two, three, or four hydrophilic hydroxyl-group-functionalized DPOSS cages attached via one junction point to a hydrophobic polystyrene (PS) chain. These hybrid polymeric amphiphiles with precisely defined chemical structure controllable architecture...
Mental health literacy (MHL) is rarely reported in the Chinese elderly. This study explored pattern of MHL elderly relation to depression, anxiety and poor sleep quality.A cross-sectional was conducted among older adults Guangzhou, south China. Participants were investigated face-to-face using National Health Literacy Scale, Patient Questionnaire-9 item (PHQ-9), 7-item Generalized Anxiety Disorder (GAD-7) Pittsburgh Sleep Quality Index (PSQI). Scale contains three dimensions: mental...
Chronotype and sleep quality have been shown to play significant roles in influencing people’s physical mental health. The current study focuses on examining the relationship between chronotype among Chinese college students exploring mediating role of bedtime procrastination moderating hygiene awareness. A sample 2822 (female = 71.4%) aged 17 29 years (M 19.77, SD 1.41) were included completed measures Pittsburgh Sleep Quality Index (PSQI), Morningness–Eveningness Questionnaire (MEQ),...

Abstract Thermal runaway poses a critical safety concern for fuel cells, significantly impairing their performance and durability. Uneven current often leads to uneven temperature, exacerbating the risk of thermal runaway. The inadequate electrical conductivity gas diffusion layer (GDL) is identified as primary cause issues. To address this, multilayer composite (MC‐GDL) proposed designed enhance both conductivity. in‐plane MC‐GDL reaches an impressive 9.1 × 10 4 S m −1 . Under extreme...
A series of noncrystalline ABn dendron-like giant molecules DPOSS–MPOSSn (n = 2–6, DPOSS: hydrophilic polyhedral oligomeric silsesquioxane (POSS) cage; MPOSS: hydrophobic POSS cage) were synthesized. These samples present a thermodynamically stable phase formation sequence from the hexagonal cylinder (plane group P6mm), to Frank–Kasper (F–K) A15 (space Pm3̅n), and further F–K σ P42/mnm), with increasing number MPOSS in single molecule (n, 2 6). Moreover, for DPOSS–MPOSS5 DPOSS–MPOSS6, an...
How biomembranes are self-organized to perform their functions remains a pivotal issue in biological and chemical science. Understanding the self-assembly principles of lipid-like molecules hence becomes crucial. Herein, we report mesostructural evolution amphiphilic sphere-rod conjugates (giant lipids), study roles geometric parameters (head-tail ratio cross-sectional area) during this course. As prototype system, giant lipids resemble natural lipidic by capturing essential features. The...
Correlating nanoscale building blocks with mesoscale superlattices, mimicking metal alloys, a rational engineering strategy becomes critical to generate designed periodicity emergent properties. For molecule-based nevertheless, nonrigid molecular features and multistep self-assembly make the molecule-to-superlattice correlation less straightforward. In addition, single component systems possess intrinsically limited volume asymmetry of self-assembled spherical motifs (also known as...
For liquid crystals (LCs) and crystalline polymers (LCPs), a chiral smectic C (SmC*) phase has been mandatory for breaking the symmetry achieving ferroelectricity. However, this SmC* leads to rather low spontaneous polarization (Ps, 0.1-5 mC/m2), which limited their usage in various electronic electro-optical applications. In mini-review, we highlight three new types of ferroelectric LCPs with high Ps values reported last decade. The first system refers nematic LCs LCPs. large dipole moment...
