Then, the nucleation effects of <em>E. huxleyi</em> coccoliths as seeding agent (0.5, 1, 3, or 5 wt % additions) and limestone filler (5 and 15 wt % cement replacements) were studied using isothermal conduction calorimetry and compressive strength testing. The results were compared with five commercially available CaCO₃ sources used as nucleation agents and fillers. While the high surface area of coccoliths (12.22 m²/g) enhanced water demand, it also enhanced nucleation during cement hydration without accelerating hydration, leading to enhanced early-age strength without detriments to 28-day strength.

Inspired by the dynamic equilibrium of atmospheric clouds, we present thermo-induced reversible nanoemulsification of biphasic liquid systems through cyclic heating and cooling processes. With our strategy, nanodroplets dissipate through dissolution upon heating and re-emerge through nucleation upon cooling, driven by temperature-dependent solubility. Combining experimental, numerical, and theoretical studies, we identify the critical conditions for nanoemulsification, elucidate the physicochemical mechanism of nucleation, and predict the size of nanodroplets. Thermo-induced nanoemulsification (TINE) offers a reversible, facile, and scalable method for energy-efficient, surfactant-free production of nanoemulsions, characterized by good emulsion stability, diverse emulsion types, and precise control over droplet size.</div></div>","PeriodicalId":388,"journal":{"name":"Matter","volume":"8 7","pages":"Article 102103"},"PeriodicalIF":17.3,"publicationDate":"2025-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143806422","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}

RNA is transcribed in hydrogel “generators” and degraded in bulk, producing a sustained concentration gradient with a well-defined shape. The concentrations of fields produced by generators sum so that composite fields with complex patterns, e.g., hills and valleys, can be created by prescribing generator positions. Using an empirical model, we automatically design a desired field by optimizing generator placements. This versatile approach supports multi-hour stability and is readily extensible to 3D or to fields of multiple sequences.

This TMT process resulted in significant microstructural refinement, including grain-size reduction, a high density of dislocations, and crucially, the formation of homogeneously distributed B2 and Zr₅Al₃-type nanophases. These nanophases are a direct consequence of solute segregation to dislocations during cold rolling, followed by precipitation during a subsequent heat treatment. The good mechanical properties of this RHEA are attributed to the combined effects of solid-solution strengthening, grain-boundary strengthening, dislocation strengthening, and precipitation hardening. Interestingly, solute segregation along dislocations is observed after cold rolling, resulting in the formation of B2 and Zr₅Al₃-type phases during the post-rolling heat treatment.

Our previous work to date entailed reacting Ti-precursors (e.g., TiB₂, TiOSO₄, TiN, TiC, etc.) with the quaternary ammonium compound (quat) tetramethylammonium hydroxide (TMAH) for tens of hours under ambient pressures at temperatures ranging from 50°C to 80°C. Herein, we expand the list of quats that result in 1DL NFs to tetraethylammonium hydroxide (TEAH), tetrapropylammonium hydroxide (TPAH), tetrabutylammonium hydroxide (TBAH), and choline hydroxide (ChoH). We also show that tetrabutylphosphonium hydroxide (TBPH) can be used to the same end result. These quats and TBPH are less toxic than TMAH, especially Cho⁺, which is fully biocompatible. And, while all the quats and TBPH result in the same 1D product, their de-flocculation in various organic solvents is different. Reacting with less polar quats (e.g., TBA) and washing with less polar solvents (e.g., dichloromethane) favors the formation of porous mesostructured particles. 2D structures are favored if the opposite is chosen. Said otherwise, by the judicious choice of a quat (e.g., TPAH) and solvent (e.g., <em>tert</em>-butanol) combination, we produced stable 1DL colloidal suspensions in dimethyl sulfoxide, methanol, ethanol, acetonitrile, isopropyl alcohol, butanol, and acetone. This enhanced colloidal stability is critical in applications in coatings, inks, and catalytic systems where non-aqueous stable dispersions are paramount. The high band-gap energies, E_g, measured (3.8–3.9 eV) confirm quantum confinement. The E_g are also quite insensitive to <em>d</em> spacings between the 2D sheets. These 1DLs exhibit significant adsorption and dye (rhodamine 6G) degradation capabilities. For example, TEA-1DL colloidal suspensions adsorb 64% of the dye in the dark in about 5 min and decolorize 99% of the remaining dye within 30 min under the irradiance of one sun.</div></div>","PeriodicalId":388,"journal":{"name":"Matter","volume":"8 7","pages":"Article 102260"},"PeriodicalIF":17.3,"publicationDate":"2025-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144523023","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}

PMs are engineered materials that exhibit frequency ranges, known as band gaps, where wave propagation is significantly inhibited. Our findings show that these band gaps effectively mitigate unsteadiness in hypersonic shockwave/boundary-layer interactions (SWBLIs). Specifically, we analyze a bilayer PM subsurface exposed to a Mach 7.2 cylinder-induced SWBLI, comparing its performance to a rigid wall control. Spectral analysis reveals that the PM selectively attenuates disturbances and significantly stabilizes flow structures away from the fluid-PM interface.
