However, whether the critical strain is uniquely determined by temperature remains unclear, particularly at the dendrite scale. In this study, solidification-cracking behavior in an Fe-15Mn-10Cr-8Ni-4Si alloy was investigated using in-situ synchrotron X-ray transmission imaging combined with local strain and temperature analyses. Crack-initiation events were identified from the time-resolved X-ray images, and the corresponding critical equivalent strains and critical temperatures were extracted at individual positions along the crack path. Solidification cracking occurred over approximately 1320-1000°C, corresponding to the effective solid-liquid coexistence region predicted by a Scheil-Gulliver calculation. The median critical strain was higher at lower temperatures and generally decreased toward higher temperatures. A broad critical-strain distribution remained within each 30°C temperature range. After subtraction of the temperature-bin median, the remaining variation was spatially nonuniform along the crack path. Comparison with a non-cracking case showed that most equivalent-strain values remained below the critical-strain distribution obtained in the cracking case, although the upper tail partially overlapped its lower part. These results provide experimental evidence that the critical strain at solidification-crack initiation is better represented as a temperature-dependent distribution than as a single-valued curve. The physical factors governing the distribution width and spatial variation remain to be identified.","PeriodicalId":21588,"journal":{"name":"Science and Technology of Advanced Materials","volume":"27 1","pages":"2736326"},"PeriodicalIF":6.6,"publicationDate":"2026-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13686218/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149246434","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ultrafast optical Kerr effect (OKE) spectroscopy can follow molecular reorientational relaxation in liquid phase, but it is not obvious whether the slow picosecond component arises from the rotation of the solute itself or from water slowed by the increased viscosity when it is applied to aqueous solution systems. Here, we use OKE spectroscopy to investigate the reorientational dynamics of three amino acids (alanine, proline, and lysine monohydrochloride) in aqueous solution in terms of concentration, temperature, and chirality. Using poly(vinyl alcohol) (PVA) as a control, we found that increasing the macroscopic viscosity by approximately eightfold did not alter the reorientational relaxation time of water. This result indicates that OKE provides information on the local rotational friction associated with the solute and highlights its unique role as a technique complementary to rheometry, which measures macroscopic viscosity. This study provides new insight into the local rotational environment experienced by solutes in aqueous amino acid solutions.","PeriodicalId":21588,"journal":{"name":"Science and Technology of Advanced Materials","volume":"27 1","pages":"2736324"},"PeriodicalIF":6.6,"publicationDate":"2026-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13700517/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149272904","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The emission perpendicular to the surface and the independence of the peak photon energy on emission direction are significant features, unlike those of surface phonon polaritons (SPhP). However, this emission is restricted to the optical polarization perpendicular to the stripes. In this research, two-dimensional (2-D) square-lattice and ring-type surface structures are fabricated and almost unpolarized LORE spectra are observed at 8.5 THz at 630 K, persisting to 323 K. Although the local spectrum minima due to optical absorption via SPhP show dependence on structural periods, the LORE peak energy is found to be robust. The LORE intensity averaged over polarizations is nearly twice that of the one-dimensional structure. In contrast, when fabricating a rectangular emission window with the side length short enough for the LO-phonon coherence, no LORE is observed. A finite-difference time-domain calculation suggests that this phenomenon is due to the disappearance of electric dipoles. Thus, two-dimensional structures enable control over the allowance and prohibition of THz wave emission, as well as its polarization.","PeriodicalId":21588,"journal":{"name":"Science and Technology of Advanced Materials","volume":"27 1","pages":"2724893"},"PeriodicalIF":6.6,"publicationDate":"2026-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13715342/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149300338","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we demonstrate thermally evaporated C60 based films as high-rate anodes in planar LiPON-based thin-film solid-state half-cells. Structural characterization by X-ray diffraction and transmission electron microscopy shows that the as-deposited films lack long-range fullerite crystallinity and are best described as structurally disordered C60-derived layers. Electrochemically, the 200 nm films deliver reversible multistep lithiation with capacities up to ~560 mAh g-1, exceeding the nominal Li12C60 composition, and retain substantial capacity at extreme C-rates. The cells provide ~410 mAh g-1 at 1 mA cm-2 and ~220 mAh g-1 at 12 mA cm-2, corresponding to real rates of approximately 75 C and 1600 C, respectively. Long-term cycling is highly stable, with capacities above 400 mAh g-1 at 75 C maintained over more than 7000 cycles and only minor impedance growth. Impedance analysis indicates that, at the highest current densities, the cell polarization is heavily influenced by the LiPON electrolyte with C60 not limiting the cell performance.

Here, first-principles calculations are used to investigate how group IV elements and the associated valence electron concentration (VEC) influence the defect energetics of body-centered cubic refractory alloys. Increasing the group IV concentration enhances lattice distortion and softens shear-related elastic moduli, effects that are generally associated with mechanical properties in refractory alloys. The VEC dependence of the dislocation-dipole formation energy persists after normalizing by the continuum-elastic dipole energy computed from the composition-dependent elastic constants, indicating a contribution beyond the linear-elastic response. A qualitatively similar trend is obtained in the chemically averaged VCA model, showing that such a trend can arise in the absence of explicit local chemical fluctuations. Direct electronic-structure evidence is still required to establish its microscopic origin. A Nye-tensor analysis of all dislocation configurations shows that the core broadens continuously with group IV content, with no composition threshold, while its sensitivity to the local chemical environment grows by an order of magnitude. Together, these results quantify how the defect energetics of a BCC medium-entropy alloy vary with group IV content and valence electron concentration, while showing that these quantities describe defect formation rather than dislocation mobility, strength, or ductility.","PeriodicalId":21588,"journal":{"name":"Science and Technology of Advanced Materials","volume":"27 1","pages":"2736330"},"PeriodicalIF":6.6,"publicationDate":"2026-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13686216/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149246394","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we investigate the optical properties of Er-doped GaAs, where the Er atoms provide the ratchet states and the intermediate states are formed by Er-related oxygen defects, to elucidate the actual energy offsets in this system. The temperature dependence of our photoluminescence data shows two activation energies, 214 meV and 10 meV, and we attribute the former to thermal activation from the Er3+ excited state labelled 4 I 11/2 to the GaAs conduction band and the latter to thermal activation from the ratchet state (4 I 13/2) to localized states related to the oxygen defects. By using photoluminescence excitation spectroscopy, we identified the 4 I 9/2 state within the GaAs conduction band, which suggests that the Er3+ ground-state manifold (4 I 15/2) is energetically aligned with the GaAs valence-band maximum.

Moreover, a single physical stimulus is often inadequate to achieve sustained tumor suppression, highlighting the need for complementary therapeutic modalities.

The engineered nanofibers exhibited enhanced piezoelectric performance under ultrasound stimulation, alongside efficient heat generation under magnetic excitation.
