PC coatings with structural colors are fabricated by embedding method through cooperative DSDV process. • Different from traditional strategies, the embedding method adopts a new “coating before assembly” strategy. • Conformal PC coatings are prepared on 33 substrates, including boards, fabrics, inorganics, metals, plastics, and rubbers. • The embedding method works for the polystyrene-arylate, alkyd, polyurethane, and polyvinyl alcohol-based PC coatings. Colloidal photonic crystal (PC) coating has wide application in automotive manufacturing, textile dyeing, packaging and printing, cosmetics and personal care, and anti-counterfeiting materials. However, the traditional methods based on strategies of “coating after assembly” and “coating along with assembly” show poor compatibility with the substrates and polymer components. Here, a new method based on the embedding of colloidal crystals into the precoated polymer layer was developed to prepare durable PC coatings with bright and uniform structural colors. This embedding method pioneers a new synthetic strategy, which is “coating before assembly”. The coating formation is proved to follow the DSDV mechanism, which refers to the cooperative “polymer dissolution”, “liquid photonic crystal (LPC) sinking”, “polymer diffusion”, and “solvent volatilization” processes. The embedding method successfully produces conformal SiO 2 /(PS-PMMA) PC coatings with fine surface features on 33 substrates, including fibrous boards, fabrics, inorganics, metals, plastics, and rubbers, and it also works for the fabrication of alkyd resin, polyurethane, and polyvinyl alcohol-based PC coatings, which will accelerate its practical implementation in various scenarios. An embedding method following the “Coating before Assembly” strategy is developed to prepare durable PC coatings with bright and uniform structural colors. This method yields conformal coatings on diverse substrates, including fibrous boards, fabrics, inorganic materials, metals, plastics, and rubbers. Additionally, it is applicable to coatings based on acrylic resin, alkyd resin, polyurethane, and polyvinyl alcohol. Download: Download high-res image (100KB) Download: Download full-size image

Flexible alternating current electroluminescent (ACEL) devices have garnered significant research interest due to their potential applications in illumination and display. However, challenges remain in fabricating ACEL devices with high brightness and excellent working stability over a large luminescent area. In this study, we demonstrate a simple aerosol spraying method with modified luminescent ink to fabricate meter-scale flexible ACEL devices. In the fabrication process, the particle dispersibility of luminescent ink and the uniformity of sprayed film have been significantly improved. This improvement is primarily attributed to the introduction of long-chain molecular groups of the surfactant, which can bind to the surface of ZnS:Cu luminescent particles at one end, while the other end remains suspended in the oily solvent, providing substantial steric hindrance. The fabricated planar thin-film ACEL devices demonstrated excellent substrate compatibility and flexibility, with exceptional operational stability in high-temperature, humid, and water-rich environments. Remarkably, we achieved a maximum brightness of nearly 500 cd·m −2 in small-sized devices, while a brightness of 303.3 cd m −2 from an ultra-large device of 1.2 m × 1.2 m. These devices have been further explored as navigation signs for autonomous takeoff and landing of industry drones.

Although the compound profiles in extracts are linked to the solid-phase microextraction (SPME) position (headspace or liquid), a theoretical interpretation of this scenario has not yet been provided. In this study, the dynamic linked position unity (DLPU)-SPME is proposed as a method that allows balanced extraction of volatile and semi-volatile compounds. Furthermore, the pH, temperature, and salt were confirmed as the key factors affecting the extraction efficiency of DLPU-SPME. Theoretical calculations indicated that K fs 0 K fs is a key factor directly indicating the SPME extraction position ( K fs 0 K fs > 1, headspace; K fs 0 K fs = 1, any position; K fs 0 K fs < 1, in liquid), while the target analytes determined that V h K hs + V s V e K fh K hs regulates the effect of the extraction position on the extracted amount. The proposed DLPU-SPME method containing both extraction positions (i.e., headspace and liquid) can simultaneously extract volatile and semi-volatile compounds, thus avoiding extraction bias.

Textile-based light-emitting devices are attracting more and more attention because of their potential applications in smart clothing, human–computer interfaces, safety warnings, entertainment fashion, etc. However, simple and efficient manufacturing of luminescent devices on fabrics even clothing with excellent stretchability and washability remains challenging. Here, a solvent-free thermal lamination process combined with laser engraving has been proposed to fabricate electroluminescent (EL) devices on textiles. All the preprepared components, such as the bottom electrode, the EL layer, and the top transparent electrode, were thermally laminated on the surface of textiles employing thermoplastic polyurethane (TPU) as the binding matrix. The stretchability, luminance, and interface adhesion of the EL devices were systematically studied, showing excellent mechanical durability at high temperature, in humid environments, withstanding repeated machine washing, and resistant to various forms of physical damage. As a demonstration of potential application, textile-based EL devices were fabricated, which could display colored and pixelated patterns as well as dynamic images. The thermal lamination technology developed in this work can potentially enable people to DIY (do it yourself) fabricate light-emitting devices on clothing using daily tools, which could facilitate the widespread use of textile-based wearable displays.

The odor-active compounds in Fu-brick tea and their release behaviors during boiling-water were studied. Fifty-one odor-active compounds were identified, and their release behaviors were identified by continuously recovering 16 sections of condensed water combined with sensory, instrumental, and nonlinear curve fitting analysis. The odor intensities of condensed water and the concentrations of odor-active compounds could be significantly fitted ( p < 0.01) to power-function type curves. Hydrocarbons showed the fastest release rate, while organic acids showed the slowest. The release rates had very little correlation with their concentrations, molecular weights, and boiling points. Most odor-active compounds (≥70 %) released need to evaporate more than 24 % of the added water during boiling-water extraction. Meanwhile, on the basis of odor activity value (OAV) calculation, the aroma recombination experiments were performed to explore the odor-active compounds that made major contributions to the formation of the aroma profile of each condensed water.

A novel dual emissive fluorescent probe SFQ was designed and synthesized by linking dicyanisophorone and thiophene aldehyde units to carbazole groups. The probe SFQ has high selectivity and sensitivity toward ClO − . Upon addition of ClO − to the solution of probe SFQ resulted in a noticeable color changed from orange to pink under natural light. Meanwhile, SFQ could make a ratiometric fluorescence response to ClO − at two different excitation wavelengths, with the change of color from orange-red fluorescence to cyan fluorescence under the 365 nm UV lamp. The detection limit was 1.4 × 10 −7 mol/L under ratiometric conditions. The study on the reaction mechanism showed that when SFQ reacted with ClO − , the cyano group disappeared and the cyclic ketone SFQ -O came into being. Furthermore, probe SFQ was successfully used to monitor ClO − in HepG2 cells and detect ClO − in actual environmental water samples.

Hydrogen sulfide (H2S) is an important endogenous gas signal molecule in living system, which participates in a variety of physiological processes. Very recent evidence has accumulated to show that endogenous H2S is closely associated with various cancers and can be regarded as a biomarker of cancer. Herein, we have constructed a new near-infrared fluorescent probe (DCP-H2S) based on isophorone-xanthene dye for sensing hydrogen sulfide (H2S). The probe shows remarkable NIR turn-on signal at 770 nm with a large Stokes shift of 200 nm, together with high sensitivity (15-fold) and rapid detection ability for H2S (4 min). The probe also possesses excellent selectivity for H2S over various other analytes including biothiols containing sulfhydryl (−SH). Moreover, DCP-H2S has been successfully applied to visualize endogenous and exogenous H2S in living cells (293T, Caco-2 and CT-26 cells). In particular, the excellent ability of DCP-H2S to distinguish normal mice and tumor mice is shown, and it is expected to be a powerful tool for detection of H2S in cancer diagnosis.

A novel dicyanoisophorone-based red-emissive fluorescence probe (YT) with large Stokes shift (230 nm) was synthesized for rapid (<20 s) and selective detection of hypochlorite ions in nearly 100% aqueous medium. YT responded to hypochlorite ions via the ClO − -promoted oxidative deprotection of thioacetal , leading to a red shift in its fluorescence maximum from 590 nm to 640 nm accompanied by naked-eye color change from orange to red. The emission response of the probe toward ClO − presented a good linear relationship in the 5–160 μM concentration range, with the LOD of 4.64 μM. Further, the probe YT was successfully employed in exogenous and LPS-induced endogenous imaging of ClO − in live cells and zebrafish, demonstrating its potential applications in biological science.

Textile-based electronics hold great promise because they can endow wearable devices with soft and comfortable characteristics. However, the inherent porosity and fluffiness of fabrics result in high surface roughness, which presents great challenges in the manufacture of high-performance fabric electrodes. In this work, we propose a thermal transfer printing method to address the above challenges, in which electrodes or circuits of silver flake/thermoplastic polyurethane (TPU) composites are prefabricated on a release film by coating and laser engraving and then laminated by hot-pressing to a variety of fabrics and textiles. This universal and scalable production technique enables fabric electrodes to be made without compromising the original wearability, washability, and stretchability of textiles. The prepared fabric electrodes exhibit high conductivity (5.48 × 104 S/cm), high adhesion (≥1750 N/m), good abrasion/washing resistance, high patterning resolution (∼40 μm), and good electromechanical performance up to 50% strain. To demonstrate the potential applications, we developed textile-based radio frequency identification (RFID) tags for remote identification and a large-sized heater for wearable thermotherapy. More importantly, the solvent-free thermal transfer printing technology developed in this paper enables people to DIY interesting flexible electronics on clothes with daily tools, which can promote the commercial application of smart textile-based electronics.

The sensory qualities , aroma profile, and microstructural features of instant Pu-erh teas (IPTs) produced by electrostatic spray drying (ESD) were evaluated by sensory and instrumental analyses and compared with those produced by other drying methods (freeze-drying [FD], vacuum drying [VD], and conventional spray drying [CSD]). The sensory qualities of ESDIPT were similar to those of FDIPT, and better than those of VDIPT and CSDIPT. Eighty-eight volatiles were detected in all IPTs, and 45 odor-active compounds were captured. Most of their OAVs were higher in ESDIPT than in VDIPT and CSDIPT but were lower than those in FDIPT. Dihydro-β-ionone had the highest OAV. Aroma recombination experiments were performed to verify the identification results. ESDIPT was present in the shape of microspheres with many regular concave surfaces, which was different from those treated by other drying methods. In terms of sensory quality and productivity, ESD would be a potential method for IPT production.

Volatiles in four Allium tenuissimum flower samples were detected and characterized by headspace-gas chromatography-olfactometry-mass spectrometry, and odor activity values. The key aroma compounds were determined by combining the sensory analysis with the omission and recombination experiments. The results illustrated that a total of 36 volatiles were identified and divided into six types, including sulfur-containing compounds, aldehydes, alcohols, ketones, nitrogen-containing compounds, and others. The sulfur-containing compounds and aldehydes were the two most abundant compounds in A. tenuissimum flower. The volatiles were quantified through authentic reference compounds, and the contents of these compounds in four A. tenuissimum flower samples were obtained. Five key aroma compounds of A. tenuissimum flower were confirmed as dimethyl disulfide, dimethyl trisulfide, linalool, 2-methylbutanal, and nonanal. Among these, the predominant compounds dimethyl disulfide and dimethyl trisulfide having strong onion and sulfur aroma, significantly contributed to the aroma of A. tenuissimum flower. The main aroma profiles of A. tenuissimum flower were onion, sulfur, flower, green and burnt. The closer the geographical location and environment of A. tenuissimum flower growth are, the more similar their chemical composition.

Herein, an environmentally friendly biomimetic strategy was proposed and validated for the catalytic hydrogenation reaction in live bacteria. First, we used a thermophilic hydrogen-producing bacterial strain to in situ prepare ultrafine gold nanoparticles (AuNPs) and palladium nanoparticles (PdNPs). Then, by utilizing AuNPs or PdNPs as catalysts and on-site hydrogen gas generated directly through living thermophilic hydrogen-producing bacteria, we realized highly efficient asymmetric hydrogenation reactions.
