Abstract Environmentally sensitive fluorescent probes (including AIEgens) play pivotal roles in numerous biological studies. Many of these functional materials are developed based on the twisted intramolecular charge transfer (TICT) mechanism. However, TICT tendency dialkylated amino groups biocompatible main‐stream fluorophores (i.e., coumarins and rhodamines) is weak, limiting their sensitivities. Herein, by replacing donors with an N ‐methylpyrrole group to enhance TICT, a simple general...

Iris × germanica L. (bearded iris) is a popular ornamental plant with numerous commercially important cultivars; however, little known about the genetic diversity and population structure of species, as limited DNA markers have been explored. In this study, 34 722 expressed sequence tag (EST)-simple repeat (SSR) loci were identified from RNA sequencing data. The most abundant SSR motifs belonged to tri-nucleotide type, which common AGG/CCT followed by AAG/CTT. Overall, 50 primer pairs...

Discriminative sensing for mixture by either fluorescent sensor or other sensors remains a challenge. This issue is attributed to the absence of separation unit prior sensor. Here, we report new medium, named porous monolith, which can separate and meanwhile be integrated into discriminative detection. The monoliths are prepared via polymerization 4,4′,4″,4‴‐(ethene‐1,1,2,2‐tetrayl)tetrabenzaldehyde with diamines. Their photophysical property hierarchical porosity systematically studied. On...

Nowadays, test strips are widely applied, but their use is mostly limited to the qualitative or half-quantitative analysis of targets. The main reason for "Coffee Ring Effect" (CRE) probe materials, which leads a heterogeneous distribution and poor testing reproducibility sensitivity. In present work, fluorescent strip was fabricated with suppressed CRE silver nanocluster (AgNC) probes coated by gelatin (Gel) under vacuum-aided fast lyophilization. Uniform stable deposition AgNC achieved...

Developing highly flexible, mechanically strong, and efficient microwave absorption materials is urgently needed to solve the electromagnetic (EM) wave pollution problems in areas of fast-growing electronic devices. Herein, poly(vinylidene difluoride) (PVDF) composite nanofibrous mats combined with functionalized carbon nanotubes (CNTs) were fabricated by a facile electrospinning process. The hydrogen-bonding heterointerfaces between PVDF acidified CNTs (a-CNTs) favored interfacial...

d-Lactic acid holds significant industrial importance due to its versatility and serves as a crucial component in the synthesis of environmentally friendly biodegradable thermal-resistant poly-lactic acid. This polymer exhibits promising potential substitute for nonbiodegradable, petroleum-based plastics. The production d-lactic from lignocellulosic biomass, type biorenewable nonfood resources, can lower costs improve product competitiveness. Glucose xylose are most abundant sugar monomers...

Inspired by visual-tactile cross-modal bidirectional mapping of the human brain, this paper introduces a novel approach to between visual and tactile data, an area not fully explored in predominantly unidirectional existing studies. First, we adopt separate Variational AutoEncoder (VAE) models for data. Furthermore, introduce conditional flow model built on VAE latent feature space, enabling data using one model. The experimental results show that our method achieves excellent performance...

Ferromagnetism in graphite/graphenes is attractive for fundamental science and potential applications carbon-based magnetism spintronics. In this work, we show that magnetic particle inspection can be miniaturized to detect local moments with a high spatial resolution of ∼1.0 nm using scanning electron microscopy. A metal nanowire adjacent nanogap found at the edges graphenes graphite atoms (Fe, Co, Ni, Mn, Pd, Al), whereas no similar characteristics are diamagnetic metals (Au, Ag). By...
