However, ZnO nanoparticles are easy to agglomerate, which will significantly affect the ultraviolet absorption and bacteriostatic properties, and the reactive oxygen species induced by the photocatalytic activity may result in irreversible secondary damage to the skin. Herein, the ZnO nanoparticles are dispersed uniformly on the surface of latex particles, and these composite particles are used as shell materials to construct self-assembled colloidosomes by high-gravity technology, which can improve the application properties with synergistic enrichment of the hollow structure. The ultraviolet resistance of colloidosomes is significantly higher than that of the pure ZnO nanoparticles. The higher the loading capacity, the more obvious the inhibition effect of colloidosomes on the growth of Gram bacteria. Furthermore, the antioxidant anthocyanin is in situ encapsulated in colloidosomes, and at a concentration of 2 g/L, the high free radical scavenging rate of 78% can be achieved. The construction of multifunctional colloidosomes provides a route for sunscreen and cosmetics applications.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"80 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2024-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142858286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper describes the development of a stable passive Q-switched ytterbium-doped fiber laser (YDFL) with operating wavelengths of 1032.9 and 1030.6 nm using two saturated absorbing materials: tantalum sulfide (TaSSe) and tantalum disulfide (TaS2). Our experimental results show that TaSSe, as a saturable absorber (SA), can generate a higher single-pulse energy and withstand higher pump power, and the single maximum pulse energy can reach 108.81 nJ. In the TaS2-SA Q-switched YDFL, increasing pump power from 180 to 330 mW results in a minimum pulse width of 3.18 μs. The maximum pulse energy is 50.68 nJ. This study showed that Janus TMD TaSSe has superior optical properties compared to traditional TMD TaS2, indicating that it has great potential for use in fiber laser development.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"97 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2024-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142858287","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, two completely nonfused MWBG acceptors, TBT-38 and TBT-43 with different alkoxy substituent positions on the thiophene rings, are synthesized. Due to the simple synthetic route and high yield, TBT-38 achieves the lowest material-only cost among high-efficiency MWBG acceptors.

In contrast, primarily due to higher exciton dissociation efficiency, charge transport capability, and favorable morphology, the TBT-38-based OPV cell delivers a PCE of 13.5% under one sun illumination, which is one of the highest results for completely nonfused OPV cells with absorption onset below 800 nm.

Herein, we present a bionic entanglement-interlocking microphase separation strategy for in situ growth of multiresponsive structural color patterns within hydrogel matrixes. The precursor solutions of common polymerization-induced phase-separated materials are used as small-molecule nutrients. The newly generated polymer networks can thus spontaneously collapse into phase-separated microspheres within hydrogels during polymerization. In particular, the dense internetwork entanglements form between the microspheres and hydrogel networks during phase separation, anchoring the microspheres firmly onto hydrogel networks to hinder their gathering. Consequently, these newly grown microspheres can be maintained at the desired nanoscale for yielding the structural blue color by light scattering. Multiresponsive schemochrome patterns can be readily created by growing different microspheres within hydrogel matrixes for multiple information encryptions. We demonstrate that this facile self-growth strategy is applicable to different polymerization-induced phase-separated materials and hydrogel matrixes, regardless of cross-linking modes and geometries.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"12 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2024-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142841269","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the structural effect of the angular/linear fusion mode and number of fused rings for A–D–A type NFAs on the photovoltaic performance in OSCs devices remains unclear. Herein, the A–D–A type NFAs (F-0Cl, IDIC8-H, and ITIC) have been selected to obtain the intrinsic role of structural design strategies including the angular/linear fusion mode and the number of fused rings. The results indicate that compared to the linear fusion mode in ITIC, the angular fusion mode in F-0Cl effectively diminishes electronic vibrational coupling within the low-frequency range, leading to lower charge reorganization during the exciton diffusion process. Meanwhile, it facilitates the generation of multiple charge transfer mechanisms at the donor/acceptor (D/A) interface and increases the rates of hole transfer. On the other hand, the decreased number of fused rings of NFAs could inhibit the exciton decay and charge recombination but increase the rates of exciton diffusion and exciton dissociation for individual NFAs and the rates of electron separation for D/A interface. This work provides theoretical insights into structural design strategies, such as linear/angular fusion, and the number of fused rings of NFA, which presents a promising outlook for further enhancing PCE of high-performance A–D–A type NFAs.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"56 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2024-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142841277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, efficient ammonia production remains challenging due to the complex electron transfer process in ENO3RR. In this study, we fabricated a Cu3P/CoP heterostructure on carbon cloth (CC) by electrodeposition and vapor deposition, which exhibits an exceptional ENO3RR performance in alkaline medium, and showcases a Faradaic efficiency of ammonia (FENH3) and an ammonia yield rate as high as 97.95% and 17,637.3 μg h–1 cm–2 at −0.9 V vs RHE. Moreover, Cu3P/CoP also has excellent catalytic activity for nitrite reduction to ammonia, with an FENH3 up to 98.31% at −0.7 V vs RHE. The experimental and theoretical calculations reveal and confirm that the formation of a heterogeneous interface between Cu3P and CoP effectively promotes the electron transfer, where Cu3P as an electron donor induces the decrease of electron density around Cu and results in an enhancement of NO2– adsorption, thereby accelerating the ENO3RR process while inhibiting the competitive hydrogen evolution reaction (HER).

For the first time, we present X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy evidence of Cu(I)–O–Si bond formation at silane-treated interfaces.

Failure mechanisms of Cu interconnects with cuprous and cupric oxide (CuO, CuII) are explored using scanning electron microscopy (SEM) and Auger electron spectroscopy (AES).

Furthermore, the biosensor displayed excellent selectivity for PAEs, with an analysis error factor below 0.277 when the concentration of interfering species was 100 times that of the target. The high performance of the biosensor was attributed to the excellent photoelectronic properties of CdS NPs/TiO2 NTs, high density of PAEs-apt for PAEs, high affinity of PAEs-apt for PAEs, and specific recognition of PAEs.
