Zn anode-based electrochromic devices(ZECDs)stand out as a highly promising technology in the upcoming era of multifunctional electronic devices,offering a blend of electrochromic capabilities and energy storage functions within a single transparent platform.However,significant challenges persist in achieving efficient patterning,ensuring long-term stability,and fast color-switching kinetics for these devices.In this study,heterogeneous tungsten oxide nanowires(W_(17)O_(47)/Na_(0.1)WO_(3),WNOs)are formulated into inkjet printing ink to assemble patternable ZECDs.The heterogeneous electrode structure of WNO enables a highly capacitive-controlled mechanism that promotes fast electrochromic/electrochemical behavior.Notably,by utilizing a three-dimensional MXene mesh modified substrate,the inkjet-printed ZECDs exhibit a wide optical modulation range of 69.13%,rapid color-changing kinetics(t_(c)=4.1 s,t_(b)=5.4 s),and highly reversible capacities of 70 mAh cm^(-2)over 1000 cycles.This scalable strategy develops the patterned electrodes with a wide optical modulation range and substantial energy storage properties,offering promising prospects for their application in next-generation smart electronics. 展开更多

AIM: To investigate the expression of triggering receptor expressed on myeloid cells-1(TREM-1) in the aberrant inflammation within the corneal epithelium at early period of fungal infection.METHODS: A total of 65 Wistar rats were randomly divided into control group, sham group and fungal keratitis(FK) group, in which the cornea was infected by Aspergillus fumigatus(A. fumigatus). After executed randomly at 8, 16, 24, 48 and 72 h after experimental model being established, the severity of keratomycosis in rats was scored visually with the aid of a dissecting microscope and slit lamp. Then corneas in three groups were collected to assess the expression of TREM-1through quantitative reverse transcription-polymerase chain reaction(RT-PCR), immunofluorescence technique and Western blot analysis. The correlation between FK inflammation and expression of TREM-1 was also analyzed.RESULTS: Corneal inflammation scores increased with time after fungal infection(F =49.74, P =0.000). The inflammation scores in FK group were obviously higher than those in sham group on the whole(F =137.78, P =0.000). Levels of TREM-1 in the infected rat corneal epithelium had elevated at 8h and peaked at 48h(P 【0.001,compared with control group). Western blot analysis also showed an obviously elevated TREM-1 level in rat corneal epithelium at 24 h and 48 h after fungal infection.Immunofluorescence technique showed that TREM-1mainly existed in corneal epithelium and infected corneal stoma of rat. TREM-1 protein expression was enhanced after fungal infection. Moreover, severity of FK inflammation was significantly related to TREM-1expression in FK(r =0.942, P =0.000).CONCLUSION: TREM-1 may contribute to amplify theinflammation in the cornea infected with A. fumigatus and play critical roles in the battle against A. fumigatus in the innate immune responses. 展开更多

Then HCECs pretreated with or without laminarin(Dectin-1 blocker, 0.3 mg/m L) and curdlan were stimulated by A. fumigatus hyphae. The m RNA and protein production of tumor necrosis factor-α(TNF-α)and interleukin-6(IL-6) were determined by real-time quantitative polymerase chain reaction and enzyme-linked immunosorbent assay, respectively. The protein level of Dectin-1 was measured by Western blot.· RESULTS: Curdlan stimulated m RNA expression of TNF-α and IL-6 in a dose and time dependent manner in HCECs. Curdlan pretreatment before A. fumigatus hyphae stimulation significantly enhanced the expression of TNF-α and IL-6 at m RNA and protein levels compared with A. fumigatus hyphae stimulation group(P 【0.05).Both curdlan and A. fumigatus hyphae up-regulated Dectin-1 protein expression in HCECs, and Dectin-1expression was elevated to 1.5- to 2-fold by curdlan pretreatment followed hyphae stimulation. The Dectin-1blocker laminarin suppressed the m RNA expression and protein production of TNF-α and IL-6 induced by curdlan and hyphae(P 【0.05).· CONCLUSION: These findings demonstrated that curdlan pretreatment enhanced the inflammatory response induced by A. fumigatus hyphae in HCECs.Dectin-1 is essential for the immunomodulatory effectsof curdlan. Curdlan may have high clinical application values in fungal keratitis treatment. 展开更多

Timbre,as one of the essential elements of sound,plays an important role in determining sound properties,whereas its manipulation has been remaining challenging for passive mechanical systems due to the intrinsic dispersion nature of resonances.Here,we present a meta-silencer supporting intensive mode density as well as highly tunable intrinsic loss and offering a fresh pathway for designable timbre in broadband.Strong global coupling is induced by intensive mode density and delicately modulated with the guidance of the theoretical model,which efficiently suppresses the resonance dispersion and provides desirable frequency-selective wave-manipulation capacity for timbre tuning.As proof-of-concept demonstrations for our design concepts,we propose three meta-silencers with the designing targets of high-efficiency broadband sound attenuation,efficiency-controlled sound attenuation and designable timbre,respectively.The proposed meta-silencers all operate in a broadband frequency range from 500 to 3200 Hz and feature deep-subwavelength sizes around 50 mm.Our work opens up a fundamental avenue to manipulate the timbre with passive resonances-controlled acoustic metamaterials and may inspire the development of novel multifunctional devices in noise-control engineering,impedance engineering,and architectural acoustics. 展开更多
