In the process of creation, innovation subjects spontaneously form a technological innovation network by cooperation and sharing knowledge and resources. The data of patent joint applications can ...reflect the cooperation and interaction between innovation subjects, so the patent technological innovation network, patent cooperation network (PCN), can be constructed based on the data. The willingness of technological innovation subjects to continue cooperation directly affects the sustainable development of innovation networks. Considering the inequality of resources between enterprises and research institutions, a new game model is established, and the influence of various factors on the evolutionary game process is analyzed. And it is applied to the weighted directed patent technology innovation network. When the patent promoter has paid the project startup fund or salary to other patent institutions that accept the invitation and can obtain government subsidies, a higher proportion of patent excess income and government subsidies will be allocated to the outgoing nodes, which will enable them to have greater patent cooperation and R&D motivation; When the excess revenue of patents can be equally distributed, even if a small amount of salary or project startup fund is paid to the inbound nodes, the cooperation between them can be promoted. The government reduces the burden on R&D institutions by providing subsidies and incentive funds, but government subsidies can promote cooperation even if they are small.

Rapid growth of electronic textile increases the demand for textile‐based power sources, which should have comparable lightweight, flexibility, and comfort. In this work, a self‐charging power ...textile interwoven by all‐yarn‐based energy‐harvesting triboelectric nanogenerators (TENG) and energy‐storing yarn‐type asymmetric supercapacitors (Y‐ASC) is reported. Common polyester yarns with conformal Ni/Cu coating are utilized as 1D current collectors in Y‐ASCs and electrodes in TENGs. The solid‐state Y‐ASC achieves high areal energy density (≈78.1 µWh cm−2), high power density (14 mW cm−2), stable cycling performance (82.7% for 5000 cycles), and excellent flexibility (1000 cycles bending for 180°). The TENG yarn can be woven into common fabrics with desired stylish designs to harvest energy from human daily motions at high output (≈60 V open‐circuit voltage and ≈3 µA short‐circuit current). The integrated self‐charging power textile is demonstrated to power an electronic watch without extra recharging by other power sources, suggesting its promising applications in electronic textiles and wearable electronics.

Recently, many studies have shown the potential use of circulating exosomes as novel biomarkers for monitoring and predicting a number of complex diseases, including cancer. However, reliable and ...cost-effective detection of exosomes in routine clinical settings, still remain a difficult task, mainly due to the lack of adequately easy and fast assay platforms. Therefore, we demonstrate here the development of a visible and simple method for the detection of exosomes by integrating single-walled carbon nanotubes that being excellent water solubility (s-SWCNTs) and aptamer. Aptamers, specific to exosomes transmembrane protein CD63, are absorbed onto the surface of s-SWCNTs and improve the minic peroxidase activity of s-SWCNTs, which can efficiently catalyze H2O2-mediated oxidation of 3,3′,5,5′-tetramethylbenzidine (TMB) and lead to a change from colorless to blue in solution. However, after adding exosomes, the aptamers are bound with CD63, leaving from the surface of s-SWCNTs through conformational changes, which results the color of solution from deep to moderate, and this can be observed by the naked eye and monitored by UV–vis spectrometry. Under optimal conditions, the linear range of exosomes is estimated to be 1.84×106 to 2.21×107 particles/μL with a detection of limit (LOD) of 5.2×105 particles/μL. Consequently, a visible and simple approach detecting exosomes is successfully constructed. Moreover, this proposed colorimetric aptasensor can be universally applicable for the detection of other targets by simple change the aptamer.
•An aptasensor based on DNA-cappeds-SWCNTs for detection of exosomes was proposed.•The s-SWCNTs that are rich in carboxyl groups and water solubility were synthesized.•The peroxidase activity of s-SWCNTs was improved and tuned by DNA.•The factors of peroxidase activity of DNA-capped s-SWCNTs were studied in detailed.

A major challenge accompanying the booming next-generation soft electronics is providing correspondingly soft and sustainable power sources for driving such devices. Here, we report stretchable ...triboelectric nanogenerators (TENG) with dual working modes based on the soft hydrogel–elastomer hybrid as energy skins for harvesting biomechanical energies. The tough interfacial bonding between the hydrophilic hydrogel and hydrophobic elastomer, achieved by the interface modification, ensures the stable mechanical and electrical performances of the TENGs. Furthermore, the dehydration of this toughly bonded hydrogel-elastomer hybrid is significantly inhibited (the average dehydration decreases by over 73%). With PDMS as the electrification layer and hydrogel as the electrode, a stretchable, transparent (90% transmittance), and ultrathin (380 μm) single-electrode TENG was fabricated to conformally attach on human skin and deform as the body moves. The two-electrode mode TENG is capable of harvesting energy from arbitrary human motions (press, stretch, bend, and twist) to drive the self-powered electronics. This work provides a feasible technology to design soft power sources, which could potentially solve the energy issues of soft electronics.

•Unpetaled pomegranate flowers are usually discarded, rich in resources and valuable for exploitation.•Ultrasound-assisted extraction of active ingredients from pomegranate ...flowers.•Ultrasound-assisted extraction of active ingredients from pomegranate flowers.
This study was designed to optimize the extraction rate of total polyphenols and ellagic acid from pomegranate flowers. Single factors were investigated for liquid-to-material ratio (5–25), ethanol concentration (20%–60%), sonication time (5–60 min), and sonication power (150–500 W). The level range of the Box-Bokhen design was determined with respect to the single-factor results. The components of each index were normalized using the entropy weighting method for obtaining the comprehensive evaluation value. Under the actual conditions, the final optimization results were 17 for liquid-to-material ratio, 43% for ethanol concentration, 10 min for ultrasonic time, and 300 W for ultrasonic power. The extracts obtained under optimal conditions were tested for the inhibition of Streptococcus mutans and its biofilm, and results showed that pomegranate flowers exerted some inhibitory effects on the bacterium. Phosphomolybdenum and FRAP assays were used, and DPPH, ABTS, and O2− radical scavenging tests were conducted, indicating that pomegranate flower extracts have good antioxidant capacity.

Rapid advancements in stretchable and multifunctional electronics impose the challenge on corresponding power devices that they should have comparable stretchability and functionality. We report a ...soft skin-like triboelectric nanogenerator (STENG) that enables both biomechanical energy harvesting and tactile sensing by hybridizing elastomer and ionic hydrogel as the electrification layer and electrode, respectively. For the first time, ultrahigh stretchability (uniaxial strain, 1160%) and transparency (average transmittance, 96.2% for visible light) are achieved simultaneously for an energy-harvesting device. The soft TENG is capable of outputting alternative electricity with an instantaneous peak power density of 35 mW m
and driving wearable electronics (for example, an electronic watch) with energy converted from human motions, whereas the STENG is pressure-sensitive, enabling its application as artificial electronic skin for touch/pressure perception. Our work provides new opportunities for multifunctional power sources and potential applications in soft/wearable electronics.
