“…Molecular-mediated self-assembly technology was applied to guide the AgNPs into the VF surface, forming a monodispersive coating. Briefly, HBPAA-capped AgNPs were firstly synthesized as described in our previous study [ 10 ]. Then, self-assembly of AgNPs on VFs were conducted by impregnation with 2 g VFs in a solution of HBPAA-capped AgNPs (4000 mg/L) at 98 °C for 3 h. AgNP-coated VFs were dried in an oven and stored in the dark.…”

Anisotropic nanomaterial-modified carbon fibers attract increasing attention because of their superior properties over traditional ones. In this study, activated carbon fibers (ACFs) “thickly overgrown” by Ag nanohair were prepared through self-assembly and rapid thermal annealing. Viscose fibers with well-dispersed silver nanoparticles (AgNPs) on surfaces were first prepared through self-assembly of hyperbranched poly(amino-amine) (HBPAA)-capped AgNPs on viscose surfaces. HBPAA endowed the AgNP surfaces with negative charges and abundant amino groups, allowing AgNPs to monodispersively self-assemble to fiber surfaces. Ag nanohair-grown ACFs were prepared by sequential pre-oxidation and carbonization. Because the carbonization furnace was open-ended, ACFs are immediately transferrable to the outside of the furnace. Therefore, the Ag liquid adsorbed by ACF pores squeezed out to form Ag nanowires through thermal contraction. FESEM characterization indicated that Ag nanohairs stood on ACF surface and grew from ACF caps. XPS and XRD characterization showed that Ag successfully assembled to fiber surfaces and retained its metallic state even after high-temperature carbonization. TG analysis suggested that Ag nanohair-grown ACFs maintained their excellent thermal stabilities. Finally, the fabricated ACFs showed excellent and durable antibacterial activities, and the developed method may provide a potential strategy for preparing metal nanowire-grown ACFs.

“…The surface of each object shows its unique texture characteristics, and this difference constitutes a colorful world (Tjnns et al, 2015). Because the basic data based on text does not contain the visual characteristics of the image, it is difficult for these descriptive keywords to fully reflect the visual characteristics of the image, especially for some features in the image such as texture and shape (Xiong et al, 2015). Flexible, efficient and accurate image retrieval strategy is one of the key technologies to solve these problems.…”

This paper explores the integration of eco-friendly materials in clothing design to maintain high-quality and aesthetically pleasing interior clothing design. Texture, as a fundamental element in images, reveals surface characteristics and aids in visual interpretation. The paper introduces an enhanced DCNN-based algorithm for extracting texture features from clothing materials. The algorithm addresses the limitation of moment invariants by combining them with boundary direction characteristics, enhancing its ability to capture shape and spatial distribution information across the entire image. Experimental results validate the algorithm’s effectiveness in image analysis and the extraction of apparel material texture features. Applying environmental design principles to the apparel design domain, this study offers a novel perspective on sustainable clothing design. Overall, the paper emphasizes the importance of using eco-friendly materials in clothing design for a better future.

“…Furthermore, due to their superparamagnetism, 26 low toxicity, 27 and high biocompatibility, 28 Fe 3 O 4 nanoparticles have become the focus of magnetic separation technology research. 29 The problem that the powdery adsorbent is difficult to separate from the adsorption system has been solved by this novel method. 30 In recent years, many magnetic ion-imprinted materials, through the combination of surface ion-imprinting and magnetic separation technology, have been synthesized to separate specific metal ions from salt lake brine.…”
