Thermocatalytic CH4 decomposition is an effective pathway toward their production, forming H2 as the only byproduct. However, catalyst deactivation due to sintering and blockage of the active sites, together with their detachment from the support remains a challenge. In this work, nickel phyllosilicate is employed as a catalyst precursor for the formation of active and stable metal sites. Surprisingly, the particles remain attached to the support, switching from the typical tip-growth reported for state-of-the-art catalysts to a base growth mechanism. The nickel nanoparticles remain stable against sintering even under harsh conditions up to 750 °C. A combination of DFT calculations, in situ TEM, and in situ XRD studies reveals that the reduction of Ni─O bonds, particularly those involving silicon-bonded oxygen (Si─O─Ni; apical oxygen), requires high temperatures. Post-activation, the small, dispersed nickel nanoparticles catalyze CH4 decomposition into carbon nanotubes and H2. Unlike prior reports, in situ XRD confirms no nickel carbide formation in the bulk. Additionally, in contrast to any known nickel-based catalyst, it is demonstrated that particles below 10 nm can effectively activate CH4 cracking, avoid encapsulation, and enable the base-growth of micrometer-long, narrow carbon nanotubes.","PeriodicalId":228,"journal":{"name":"Small","volume":"19 1","pages":""},"PeriodicalIF":13.3,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144211291","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}

The results confirm the uniform growth of Co2P-Ni2P nanoparticles (NPs) with octahedral morphology embedded in the carbon-nitrogen matrix. Co2P-Ni2P NPs (9.26 nm) express prominent interfacial interaction and a strong electronic modulation through phosphorous (P) inducing. Thus, the dual active sites (Co2P, Ni2P) synergistically increase the catalytic activity of the optimized catalyst Co2P-Ni2P-NC with excellent efficiency for ammonia borane hydrolysis with hydrogen evolution (rB = 4495 mL min−1 g−1Co), turnover frequency (TOF = 1214.4 h−1), and apparent activation energy (Ea = 36.17 kJ mol−1). The P-activated nickel foam in Co2P-Ni2P-NC contributes significantly to increasing the catalytic activity of the as-prepared catalysts.

Efficient single-cell isolation technology can significantly enhance low-abundance single-cell detection sensitivity. However, the lack of individual control over each target cell hinders further bio-analysis. Here, a “cell-on-demand” large-scale digital microfluidics platform is reported for real-time low-abundance single-cell manipulations. Compared to the conventional strategy that sequentially identifies the target cells among the heterogeneous population, the “cell-on-demand” method can conduct targeted-search-guided target cell isolation, enabled by on-demand droplet splitting. The results demonstrate that “cell-on-demand” is nearly eightfold more effective compared to the conventional strategy in dealing with low-abundance (1%) single-cells. To validate the system's feasibility, heterogenous tumor spheroids samples are used for isolating homogeneous single-target tumor spheroids, in integration with subsequent drug sensitivity testing and analysis. Drug sensitivity results show significant differences in half-maximal inhibitory concentration (IC50) for three chemotherapy drugs: Fluorouracil, Irinotecan, and Oxaliplatin, while in high consistency with well-plate-based assays. With the capability of processing both high and low-abundance samples, the proposed platform shows potential in handling various samples and in broader applications.","PeriodicalId":228,"journal":{"name":"Small","volume":"4 1","pages":""},"PeriodicalIF":13.3,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144211713","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 study explored doping alginate hydrogels with micro–nanomaterials to improve their electro–mechano–chemical performance. Carboxylated multi–walled carbon nanotubes are covalently bonded to sodium alginate (SA) through esterification, enhancing electrical conductivity and response actuation. Graphene oxide formed a compact structure via carboxyl and hydroxyl interactions, dispersing SA molecules, reducing agglomeration, and enhancing ion channel stability, which reduced resistance by 36.8%. Meanwhile, the sulfonic acid group in polystyrene sulfonate sodium improved water retention and lowered the elastic modulus. Crosslinking with SA created a stable hydrogel network, boosting anion concentration and aiding hydrated cation migration. This led to a 52.3% decrease in the elastic modulus of AHAM, resulting in a maximum actuated force–mass ratio up to 5.9 times higher than the control group.","PeriodicalId":228,"journal":{"name":"Small","volume":"16 1","pages":""},"PeriodicalIF":13.3,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144211286","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 technique utilizes fuel and oxidizer-ligands within the precursor to promote an exothermic reaction, enabling the low-temperature thin film deposition of various conductive, semiconductive, and high permittivity dielectric metal oxides. However, there are nearly no reports on the low-temperature deposition of metal sulfide thin film. In this study, leveraging the flexibility in precursor selection afforded by mist chemical vapor deposition, a solution-based combustion-assisted film deposition technique is employed to achieve the low-temperature deposition of Bi2S3 thin films. The Bi(NO3)3 and thiourea & hydrazine hydrate are applied as the oxidizer and fuel, respectively. The deposition mechanism is discussed from the temperatures and the concentration of additives (hydrazine hydrate and NaOH). The photoelectrochemical photodetectors fabricated using the solution-processed Bi2S3 thin films demonstrated interesting photodetection performance, exhibiting remarkable responsivity, rapid response speed, and high stability over 3600 s.

The resulting PS-grafted SiO2 particles exhibit exceptional colloidal stability and compatibility with conventional hydrophobic NCs, enabling their ordered coassembly into hybrid binary superlattices with unprecedented structural diversity. In particular, hidden subsurface NCs are revealed at interstitial voids in multiple binary phases, highlighting structural complexities beyond those of conventional binary colloidal crystals.

In this study, molecular dynamics (MD) simulations are employed to systematically investigate the complete Li-ion transport progress, encompassing the electrolyte, organic/inorganic SEI components, and two critical interfaces: electrolyte/organic SEI and organic SEI/inorganic SEI. The results indicate that Li ions in the organic SEI retain either full or partial solvation shells. Free energy profiles reveal that the highest energy barrier emerges at the organic–inorganic SEI interface due to the complete desolvation of Li ions and structural differences between the organic and inorganic SEI layers.

Herein, a method for post-treating perovskite films in p-MPSCs at room-temperature using halogen-free aromatic amines, including Benzylamine (BA), 1-Naphthalenemethylamine (NMA), and 1-Naphthalenecarboximidamide (NFA), is reported. The halogen-free aromatic amines prevent the formation of iodine vacancy defects in perovskite films by interacting with under-coordinated Pb2+, significantly reducing the trap state density of the perovskite films. Meanwhile, the halogen-free aromatic amines can form low-dimensional perovskites with type II energy level alignment at the perovskite film/carbon electrode interface, which significantly suppresses non-radiative recombination of interfacial carriers and reduces VOC loss. As a result, the champion power conversion efficiency (PCE) of p-MPSCs based on NFA room-temperature post-treatment is improved from 17.51% in control devices to 20.27%, and the VOC is increased from 0.975 V in control devices to 1.049 V. Furthermore, the unencapsulated p-MPSCs retained more than 95% of their initial PCE after being stored in air for 3500 h.
