Among these, BaZrS3 has attracted the most attention due to its optimal bandgap and its ability to be synthesized at relatively low temperatures. BaZrS3 exhibits a high light absorption coefficient, excellent stability under exposure to air, moisture, and heat, and is composed of earth-abundant elements. These properties collectively position BaZrS3 as a promising candidate for a wide range of applications, although traditional high-temperature synthesis has primarily been a significant challenge. In this review, we provide a critical discussion of the various synthesis methods employed to fabricate BaZrS3, including solid-state synthesis, nanoparticle synthesis, and vacuum-based as well as solution-based approaches to synthesize thin films. We also comprehensively examine the experimentally measured and theoretically calculated optical, optoelectronic, electronic, and defect properties of BaZrS3. Furthermore, this review highlights the functional devices based on BaZrS3, showcasing applications spanning photovoltaics, photodetection, thermoelectrics, photoelectrochemical water splitting, piezoelectricity, and spintronics. Lastly, we propose a future roadmap to maximize the potential of this material. Additionally, this review extends its focus to BaHfS3 and BaTiS3, discussing their synthesis methods, properties, and explored applications, thereby offering a comparative perspective on this emerging family of chalcogenide perovskites.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"9 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142981601","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to fabricate COFs with high performance for the selective transformation of SM simulant 2-chloroethyl ethyl sulfide (CEES) to nontoxic 2-chloroethyl ethyl sulfoxide (CEESO), three porphyrin-based COFs with different donor groups (R=H, OH, OMe) were synthesized. Among these COFs, COF-OMe, which possesses the strongest electron-donating ability, demonstrated a faster and higher detoxification rate of CEES at various concentrations, achieving selective oxidation of CEES to non-toxic CEESO with 99.2% conversion and 100% selectivity using white LED light irradiation within three hours. The facilitated charge transfer and separation as well as efficaciously produced reactive oxygen species (ROS) including singlet oxygen (1O2) and superoxide radical anions (O2•−) are supposed to contribute to the excellent performance. The results demonstrated that the donor-enhanced porphyrin-based COFs could act as heterogeneous photocatalysts for visible light driven organics transformation and detoxification of sulfur mustards.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"24 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142981582","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional fecal waste management methods are insufficient, particularly in addressing the related health risks and environmental threats. This study explores the synthesis of biochar from pig manure as a carbon substrate to disperse and stabilize Cu nanoparticles, resulting in the formation of an efficient Cu-NB-2000 electrocatalyst for electrocatalytic CO2 reduction (ECR). Through characterization analyses and electrolysis tests, the structure-activity relationships were evaluated, revealing enhanced catalytic activity and selectivity towards value-added multicarbon products. At optimal potential, the catalyst achieved a remarkable faradaic efficiency for ECR (87.14%) and multicarbon products (44.80%), outperforming previously reported biochar-supported Cu catalysts. The high selectivity was attributed to the substantial presence of pyridine N and the distinctive Cu-N coordination structure. This work introduces, for the first time, a method for preparing an ECR catalyst by loading Cu nanoparticles onto biochar derived from pig manure. This approach not only promotes the valorization of organic waste but also efficiently converts CO2, offering an effective strategy for an integrated \"pollution reduction-carbon mitigation\" management system.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"7 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142981583","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this critical mechanism, we present NanoAid, a biomimetic nanoplatform designed to target inflammatory pro-tumor processes to advance glioblastoma chemotherapy. NanoAid employs macrophage-membrane-liposome hybrids to optimize the delivery of COX-2 inhibitor parecoxib and paclitaxel. By inheriting macrophage characteristics, NanoAid not only efficiently traverses the blood-brain barrier and precisely accumulates within tumors but also enhances cancer cell uptake, thereby improving overall anticancer efficacy. Notably, the combination of parecoxib and paclitaxel effectively disrupts inflammatory pro-tumor processes while inducing a synergistic effect that inhibits tumor growth, overcomes therapeutic resistance, and minimizes adverse effects. This results in substantial tumor growth inhibition and extends the median survival of tumor-bearing mice. Thus, our study bridges clinical insights with fundamental research, potentially revolutionizing tumor therapy paradigms.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"16 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142975226","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Black silicon (b-Si) would be an ideal candidate for some applications due to its nanoscale topography made with a convenient lithography-free step and Complementary Metal-Oxide-Semiconductor (CMOS) compatible fabrication process. However, its use is hindered by serious issues with mechanical robustness. This study presents ‘nanojungle b-Si,’ characterized by elongated and deep nanostructures and fabricated through photoresist micromasks associating with Bosch etching. These nanojungle structures exhibit enhanced robustness and sustain superhydrophobicity under abrasive conditions, outperforming traditional ‘nanograss b-Si.’ Optical analysis indicates that the nanojungle structures dissipate abrasive impact energy more effectively, preserving surface roughness and hydrophobicity. Notably, nanojungle b-Si maintains its superhydrophobicity even after impinging by 20 g of sand impacting from a height of 40 cm. This advancement in b-Si surfaces holds significant potential for enhancing future technological applications.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"76 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142975232","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, a high gate bias is indispensable for perovskite-based phototransistors to optimize detection performances, since ion migration seriously screens the gate electric field, and the deposition process introduces intrinsic defects, which induces severe leakages and large power dissipation. In this work, an ultrasensitive phototransistor based on (PEA)2SnI4 perovskite and Al:HfO2 ferroelectric layer is meticulously proposed, working without an external gate voltage. The nonvolatile remanent polarization provides a stable floating-gate to locally define potential profile, regulate Schottky barrier contact, modulate carrier transport properties and charge redistributions, which facilitates ultralow level of dark current and accurate photocurrent extraction at zero gate bias. Consequently, the fabricated phototransistor exhibits an outstanding responsivity and detectivity of 4918 A W-1 and 2.15×1015 Jones, respectively. The developed phototransistor is positioned to contribute to advancements in optoelectronic applications including large-scale intelligent sensor arrays, light-wave communications and integrated circuits.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"41 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142975272","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we have successfully prepared a well-defined core-satellite superstructure (ZIF-8@Ag) through solvent-induced assembly of silver nanoparticles (Ag NPs) on truncated rhombic dodecahedral ZIF-8. By wisely selecting toluene as the solvent, the assembly process can be easily initiated through ultrasonic treatment and allows for precise morphological adjustments to build a range of superstructures with different assembly density of Ag NPs via feed ratio tuning. The as-prepared ZIF-8@Ag substrate leverages the high-density distribution of Ag NPs and the exceptional adsorption capabilities of ZIF-8. This combination makes it an outstanding SERS substrate for the detection of crystal violet (CV) and methylene blue (MB), achieving a concentration as low as 1×10-10 M and 1×10-9 M, respectively. Moreover, the Raman analytical enhancement factor (AEF) of this ZIF-8@Ag substrate can reach 1.35 × 107, and the Raman signals exhibited high homogeneity.

The preparation of catalytically active nanoparticles on the bacterium Paracoccus yeei represents a more suitable approach to increase the reaction efficiency due to its resistance to metal salts. We introduce an efficient method that significantly reduces the preparation time of Pd nanoparticles on Paracoccus yeei VKM B-3302 bacteria to only 7 min, greatly accelerating the process compared with traditional methods. Our findings reveal the major role of live bacterial cells in the formation and stabilization of Pd nanoparticles, which exhibit high catalytic activity in the Mizoroki–Heck reaction. This method not only ensures high yields of the desired product but also offers a greener and more sustainable alternative to conventional catalytic processes.
