The double-shell structure is generally composed of a crown ether molecule sandwiched between different metal halide units. Here, we synthesize six new hybrid trimetallic halides and their solid solutions with the general formula [(<i>A</i>18C6)₃<i>MX</i>₄][<i>BX</i>₄] (where <i>A</i> = K⁺, Rb⁺, Cs⁺; M = Mn²⁺ or Mn_1–<i>x</i>Zn_{<i>x</i>²⁺}; <i>B</i> = In³⁺; <i>X</i> = Cl^– or Br^–), abbreviated as <i>A</i>-<i>M</i>-<i>X</i>. Through the structural analysis of the crystal structure and characterizations of the optical properties of these materials, we have found a direct correlation between the photoluminescence quantum yield (PLQY) and the suitability of the coordination between the <i>A</i>-site metal and the crown ether. Specifically, as the radius of the alkali metal increases (from K to Rb), the PLQY decreases due to poorer suitability. The suitability of the coordination has been analyzed in detail by quantifying the structural parameters (i.e., <i>A</i>–O bond distance, O–<i>A</i>–O bond angle, and distance from <i>A</i> metal to the crown ether center). This trend has been further confirmed via two independent systems using solid solutions through <i>M</i>-site alloying and comparing the chloride and bromide analogs. Surprisingly, a selective coordination mode has surfaced when alloying on the A-site, where the larger alkali metal preferentially coordinates with the connected crown ether instead of the isolated one. This effective approach leads to a wide range of tunability of the PLQY from 21.7 to 95.2% within the total 12 materials. Through further analysis, we have found that the substitution of the <i>A</i>-site metal from K to Cs increases the Mn–<i>X</i> distance, which weakens the crystal field strength of Mn and aligns with the observed trend in PLQY. Our work has further expanded the material space of hybrid trimetallic double-shell clathrates and provides determining insights into controlling the structure and PLQY.</p>","PeriodicalId":7,"journal":{"name":"ACS Applied Polymer Materials","volume":"36 21","pages":"10651–10660 10651–10660"},"PeriodicalIF":7.2,"publicationDate":"2024-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142608764","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we report the first single-crystal structures of Nb₁₂MoO₃₃ and Ta₁₂MoO₃₃ that are consistent with other (3 × 4 × ∞) WR phases. The lithiation of Ta₁₂MoO₃₃ is reported to enable an isostructural comparison with Nb₁₂MoO₃₃. These two compounds have similar unit cell volumes and atomic radii, where the Ta₁₂MoO₃₃ unit cell is 0.2 vol % smaller. Despite the similarities in structure, the lithiation capacities, voltage windows, C rate-dependent capacities, and ionic diffusivities are distinctly different. These experimental trends align well with density functional theory calculations showing (1) a lower activation energy for Li transport within Ta₁₂MoO₃₃ consistent with its measured 1.5–4.9-fold higher diffusion coefficients (lithiation) and (2) an ∼25% greater measured lithiation stoichiometry for Nb₁₂MoO₃₃, which is attributed to the calculated smaller octahedral distortions (compared to Ta₁₂MoO₃₃). These findings reveal that smaller channels in Ta₁₂MoO₃₃ stabilize the transition state with 5-fold coordination, which both decreases the activation energy for diffusion and limits the extent of lithiation.

Furthermore, the interplay among the pore structure, specific mesoporosity, and accessibility of acidic sites is crucial for optimizing Florol synthesis. Strong Brønsted acid sites enhance the formation of the dehydration products, while mild-acidic Brønsted acid sites with a medium strength of accessible acid sites improve the formation of Florol.

The newly discovered marine cyanobacterium <i>Synechococcus</i> sp.

To promote its application, we developed genetic toolboxes applicable to PCC 11901 in this study. First, a cobalamin (V_B12)-independent chassis was constructed, allowing for cheaper cultivation. Second, genome copy numbers and transformation methods were, respectively, measured and optimized. Then, 14 neutral sites were identified and characterized within the genome PCC 11901, providing locations for genetic integration of exogenous cassettes. Subsequently, promoter libraries were developed, reaching an expression range of approximately 800 folds for constitutive promoters and an induction fold of up to approximately 400 for inducible promotors, respectively. As a proof of concept, natural production of the total lipid and phycocyanin was investigated using V_B12-independent chassis, which realized an increase of 14.91% with lipid content compared with that of the wild-type strain. Further, we engineered the synthetic pathways of glucosylglycerol (GG) into PCC 11901 using the established toolboxes, reaching 590.41 ± 21.48 mg/L for GG production and self-sedimentation in photoreactors with the highest OD_750 nm at 17.57 ± 0.77.

Herein, we introduce an innovative approach for producing scalable, biodegradable, and removable hot-melt adhesives, offering sustainability. Polybutylene succinate (PBS) was selected as the base polymer because of its excellent melt processability, biodegradability, and commercial availability. To impart adhesiveness, three biomass-derived tackifiers were incorporated; basic rosin, disproportionated rosin, and rosin ester. The use of a twin-screw extruder enabled the efficient mixing of the base polymer and tackifiers for large-scale production at the kilogram scale. Our investigation revealed that basic rosin exhibited optimal compatibility and wettability, which were attributed to its high acid value. The high acid value promoted rapid crystallization and minimized crystal defects. A correlation between the crystallization behavior and adhesion strength was also established, identifying the optimal composition. The optimal composition yields a satisfactory adhesion strength (2.5 N/25 mm) that makes it suitable for removable or repositionable adhesives. Additionally, our optimized adhesive exhibited sufficient biodegradability and was completely decomposed by lipase within 21 d, which has not been observed in previous sustainable hot-melt adhesive studies.
