In line with this objective, we present green preparation of a colloidal pesticide formulation using optimized lysine-derived carbon dots (LysCDs)-modified CaCO₃ (LysCDs/CaCO₃) particles as the carrier and abamectin (Abm) as the active ingredient. The loading capacity of abamectin in this colloidal pesticide (LysCDs/CaCO₃/Abm) is 1.7 to 2.1 times higher than that of its counterpart (CaCO₃/Abm) prepared without LysCDs, which is attributed to the increased specific surface area and pore volume of LysCDs/CaCO₃ particles. Due to the acid-induced degradation of CaCO₃, the release of abamectin for LysCDs/CaCO₃/Abm is accelerated under weakly acidic conditions, which is accompanied by the release of Ca²⁺ ions and the fluorescence changes of LysCDs. The incorporation of LysCDs enhances the photostability and foliar adhesiveness of this colloidal pesticide, resulting in the highest degree of foliar retention when exposed to ultraviolet (UV) light or rainfall, compared to free-form abamectin and CaCO₃/Abm. This results in the best performance of pest control on <i>Plutella xylostella</i> for LysCDs/CaCO₃/Abm in both indoor and outdoor tests. Nontarget biocompatibility evaluations show that LysCDs/CaCO₃/Abm exhibits lower acute toxicity to zebrafish and earthworms than free-form abamectin. In addition, this colloidal pesticide is favored by the minimal residue of the adjuvant material after abamectin release, which is converted into harmless Ca²⁺ ions, CO₂, and LysCDs. Therefore, this work designs a safer and more effective colloidal pesticide formulation to deliver abamectin with minimal adjuvant residue, realizing its trajectory as basically “circular and green”.","PeriodicalId":21,"journal":{"name":"ACS Nano","volume":"18 797 1","pages":""},"PeriodicalIF":17.1,"publicationDate":"2024-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142867538","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we demonstrated the “efferocytosis-like” effect of NMVs endocytosed by macrophages, supplementing the TCA cycle intermediate metabolite α-KG by promoting glutamine metabolism, which in turn facilitates oxidative phosphorylation and inhibits the NF-κB signaling pathway to reprogram inflammatory macrophages to the pro-regenerative phenotype. Based on these findings, a “Trojan horse” composite fiber scaffold was constructed; this comprised a carboxylated poly-<span>l</span>-lactic acid shell encapsulated with NMVs and a core loaded with brain-derived neurotrophic factor to spatiotemporally modulate the inflammatory microenvironment by 39.23% and sustainably promote nerve regeneration by 85.67%. In vivo experiments further confirmed the effect of NMV-coated fiber scaffolds on the regulation of early innate immune inflammation and the continuous promotion of nerve regeneration.

Furthermore, understanding the van der Waals (vdW) interactions between these materials in thin-film semiconductor processes is essential. Optimizing these interactions requires precise control over the properties of the vdW interface through specific pre- or post-treatment methods. This study utilizes Se-environment annealing as a post-treatment technique, which allows for modification of the vdW gap distance and enhancement of the stability of the interfacial structure through the process of Se intercalation and deintercalation at the 2D–3D interface. The depth of Se intercalation and deintercalation is adjusted by varying the temperature and duration of the postannealing process in an Se environment. This precise control over the process enables the effective metallization of 2D semiconductors. The results indicate that expanding the vdW gap and stabilizing the interface structure through this post-treatment significantly improve the metal contact properties in devices such as field-effect transistors and photovoltaic Schottky diodes by minimizing metal-induced gap states, thus reducing Fermi level pinning. The application of Se intercalation and deintercalation techniques achieves an exceptionally low contact resistance of 773 Ω·μm between p-type WSe₂ and Au. Additionally, the integration of doping-free WSe₂ complementary metal-oxide-semiconductor (CMOS) circuits using Se-environment annealing and blocking layers is demonstrated, establishing a promising advancement in semiconductor technology.","PeriodicalId":21,"journal":{"name":"ACS Nano","volume":"24 1","pages":""},"PeriodicalIF":17.1,"publicationDate":"2024-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142867534","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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 report a Zeeman effect-driven spin-polarized band splitting phenomenon in diluted magnetic semiconductors that show efficient photocatalytic CO₂ reduction under visible-light irradiation. A flexible Ni²⁺-doped BaTiO₃ nanofiber film is used as the diluted magnetic semiconductor model to prove this concept. The interstitial Ni²⁺ dopant induces the spin-polarized bands in Ni-BaTiO₃ nanofibers to split under light excitation, generating spin-excited electrons and holes. This Zeeman effect induced by the magnetic field is more obvious since it intensifies the spin-polarized band splitting and generates more spin-excited electrons and holes, suppressing the carrier recombination and extending the carrier lifetime for CO₂ photoreduction. As a result, the evolution rates of CO and CH₄ are as high as 86.47 and 96.06 μmol/g/h under a small magnetic field of 50 mT. The proposed mechanism of Zeeman effect-driven spin-polarized band splitting is feasible to improve the CO₂ photoreduction efficiency of broadly applied diluted magnetic semiconductors.","PeriodicalId":21,"journal":{"name":"ACS Nano","volume":"31 1","pages":""},"PeriodicalIF":17.1,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142857762","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"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 ammonia yield and Faraday efficiency of electrocatalytic nitrogen reduction have been challenges due to low nitrogen solubility and competitive hydrogen evolution reaction (HER) in electrolyte solution. Herein, inspired by the asymmetric wetting behavior, i.e., superhydrophobicity/hydrophilicity, of floating lotus leaves, we demonstrated a gas-conduction electrode with asymmetric gas wetting behavior on the opposite surface, i.e., Janus-Ni/MoO₂@NF, for efficient nitrogen reduction. It can provide an abundant three-phase interface (TPI) at interfaces of Janus-Ni/MoO₂@NF in electrolyte solution to enhance the contact among N₂, electrolyte, and electrode. Ascribed to this advantage, the hydrophobic side of the Janus electrode not only can repel water molecules to suppress the HER process but also can increase the concentration of N₂ on the interface microenvironment. Consequently, the well-designed gas-conducting electrode breaks gas mass transfer limitation. Furthermore, Janus-Ni/MoO₂@NF delivers a record-high NH₃ yield rate of 5.865 μg·h^–1·cm^–2 and a Faradaic efficiency of 36.14% at an extremely low potential of 0 V vs RHE in 0.1 M Na₂SO₄ under ambient conditions, which are 22 and 18 times higher than those of the conventional electrode, respectively. Therefore, the gas-conducting electrodes can dramatically improve the activity and selectivity in electrocatalytic NRR. Additionally, the unique interface design provides inspiration for other sustainable electrochemical reactions involving gas electrocatalytic correlation.","PeriodicalId":21,"journal":{"name":"ACS Nano","volume":"27 1","pages":""},"PeriodicalIF":17.1,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142858075","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, a three-in-one strategy for a separator based on a localized electrostatic field is demonstrated to simultaneously achieve shuttle inhibition of polysulfides, catalytic activation of the Li–S reaction, and dendrite-free plating of lithium ions. Specifically, an interlayer of polyacrylonitrile nanofiber (PNF) incorporating poled BaTiO₃ (PBTO) particles and coating with a layer of MoS₂ (PBTO@PNF-MoS₂) is developed on the PP separator. Theoretical calculations and experimental work show that the electric field generated at the membrane facilitates the fast and uniform transport of Li⁺ ions, thereby inhibiting dendrite growth. Additionally, the generated electric field promotes the MoS₂ catalytic activity toward the Li–S redox reactions, particularly by reducing the reaction barriers for both the solid–liquid and solid–solid conversions. As a result, symmetrical Li//PBTO@PNF/PP/PBTO@PNF//Li cells demonstrate remarkable stability over 1200 h, and LSBs with a PP/PBTO@PNF-MoS₂ composite separator maintain a specific capacity of 318.3 mA h g^–1 after 4000 cycles at 2C, with an ultralow capacity decay rate of 0.015%.

Since, for some applications, the desired resolution for spatial omics approaches the nanometer scale, classical tools have inherent limitations when applied to spatial omics analyses, and they can measure only a limited number of targets. Nanotechnology applications have been instrumental in overcoming these bottlenecks. When nanometer-level resolution is needed for spatial omics, super resolution microscopy or detection imaging techniques, such as mass spectrometer imaging, are required to generate precise spatial images of target expression. DNA nanostructures are widely used in spatial omics for purposes such as nucleic acid detection, signal amplification, and DNA barcoding for target molecule labeling, underscoring advances in spatial omics. Other properties of nanotechnologies include advanced spatial omics methods, such as microfluidic chips and DNA barcodes.

Enhancing spin-splitting strength is promising to achieve high spin–orbit torque (SOT) efficiency for low-power-consumption spintronic devices. However, the energy scale of natural ISB at the interface is relatively small, leading to the weak Rashba effect. In this work, we report that orbital hybridization inducing additional asymmetry potential at the interface observably enhances spin-splitting strength, verified in the hexagonal boron nitride (h-BN)/Co₃Pt heterostructures. First-principles calculations suggest the sizable Rashba spin-splitting derived from the out-of-plane <i>p</i>–<i>d</i> hybridization combined with SOC at the h-BN/Co₃Pt interface.
