Optical physical unclonable functions (PUFs) are gaining attention as a robust security solution for identification in the expanding Internet of Things (IoT). To enhance and functionality PUFs, integrating multiple optical responses─such fluorescence structural color─into single system is essential. These diverse properties enable multilevel authentication, where different layers can be verified under varying light conditions, greatly reducing risk counterfeiting. However, compactly these...
Dynamic rheological measurements indicate that supra-molecules, polymers and carbogenic nanoparticles are generated successively during pyrolysis of citric acid based nanodots.
In this work, few layer graphene quantum dots (GQDs) with a size of 3-5 nm are purposely treated highly concentrated aqueous NaBH4 solutions to obtain the reduced (rGQDs). Fourier transform infrared spectroscopy (FT-IR), X-ray photoelectron (XPS) and Raman demonstrate that number carbonyl groups decreases but -OH related defects increase during chemical reduction. Green weak emissions original GQDs originate from carrier recombination in disorder-induced localized state (mainly including...
Natural-fiber-reinforced polypropylene (PP) composites with a series of advantages including light weight, chemical durability, renewable resources, low in cost, etc., are being widely used many fields such as the automotive industry, packaging, and construction. However, flammability plant fiber PP matrix restricts application range, security, use these composites. Therefore, it is great significance to study flame retardants In this paper, sisal-fiber-reinforced (PP/SF) flame-retardant...
A simple and efficient copper-catalyzed one-pot synthesis of substituted 1,2,4-triazoles through reactions two nitriles with hydroxylamine has been developed. The protocol uses readily available hydrochloride as the starting materials inexpensive Cu(OAc)2 catalyst, corresponding 1,2,4-triazole derivatives are obtained in moderate to good yields. include sequential intermolecular addition one nitrile provide amidoxime, treatment amidoxime another nitrile, intramolecular...
Fluorophores coupled with supramolecules lead to “dot” topologies in citric-acid derived carbon dots under the effect of hydrogen bonding.
Carbon dots are used to label nanofibers with four challenge–response pairs, creating an in-built and high-capacity physically unclonable function. This allows for signature, authentication data encryption of fiber PUF be demonstrated.
Versatile species have been increasingly recognized as important components and possible fluorescence origins in carbon dots synthesized via a bottom-up route. Herein, we use 2,7-naphthalenediol dimethylformamide precursors to synthesize novel type of an ethanothermal reaction. Two main luminescent with entirely different structures, including molecular fluorophores carbogenic nanodots, are independently acquired by column chromatography separation dialysis, respectively. Through detailed...
A type of trialkoxysilane‐containing naphtholoxazine compound (Naph‐boz) was successfully synthesized and combined with ammonium polyphosphate/melamine (APP/ME) as an intumescent flame retardant (IFR) to improve the flame‐retardant efficiency polyoxymethylene (POM). The Underwriters Laboratories 94 (UL94) vertical burning test, limiting oxygen index (LOI), cone calorimeter, thermogravimetric analysis (TGA), scanning electron microscopy (SEM), Raman spectral were used study properties related...
Abstract Ligand responsiveness is one of the typical mechanisms in biological organization to trigger sophisticated channel switching. Here, we report a new type helical trimer which can undergo transition between hollow single helix and an intertwined double with no cavity by complexation decomplexation Cu ions. In addition, dimensional (1D) tubes spontaneously generated from helices via π‐π interactions embedded into lipid bilayers displayed satisfactory stability efficiency. With addition...
Goblet cells and their secreted mucus are important elements of the intestinal mucosal barrier, which allows host to resist invasion by pathogens. Porcine deltacoronavirus (PDCoV) is an emerging swine enteric virus that causes severe diarrhea in pigs large economic losses pork producers worldwide. To date, molecular mechanisms PDCoV regulates function differentiation goblet disrupts barrier remain be determined. Here, we report newborn piglets, infection barrier: specifically, there villus...
Osteosarcoma (OS) is the most common bone malignancy worldwide. The vascular endothelial growth factor (VEGF) gene plays an important role in pathogenesis of OS. objective this study aimed to detect potential association between VEGF genetic polymorphisms and OS susceptibility Chinese Han population. We recruited 330 patients 342 cancer-free controls case-control study. Three single-nucleotide (SNPs) (-634 G > C, +936 C T, +1612 A) were investigated by using polymerase chain...
Benzoxazine monomers of traditional bisphenol‐A benzoxazine (BA‐a) and containing trialkoxysilane (BA‐a‐Si) were synthesized incorporated into polyoxymethylene/ammonium polyphosphate/melamine (POM/APP/ME) to improve the fire retardancy POM.
