This makes it a promising method for high-throughput screening of the plasticizing properties of novel sugar replacers.

The Thermoelectric Cooler Technology and Its Applications in Athletic Field Thermoelectric Cooling (TEC) technology has emerged as a crucial foundation for the development of modern society in various aspects. This paper begins by introducing the development of general refrigeration technology, noting that TEC has evolved as an innovative system due to its effectively combination between semiconductor materials and scientific theories, particularly in response to the design and reliability limitations of traditional refrigeration methods. Then it explains the three thermo electric effects—the Seebeck effect, Peltier effect and Thomson effect ---examines the interrelationships among them, which builds the solid scientific foundation for TEC. Next, the paper concentrates on TEC’s numerous advantages, such as precise temperature control, adaptability in harsh circumstances, vibration and noise eliminating. These attributes give TEC a competitive edge in comprehensive fields like medical, commercial and military, ranging from grand industry to individuals. After that, the paper specifically takes athletic field as a representative example. Inventions like cooling vests, handheld fans, the intellectual national football league (NFL) helmet developed at Purdue University, and the TEC embedded seats have enhanced people’s life quality and contributed to advancements in scientific practices. In conclusion, while challenges still remain, the prospects of TEC technology are promising and bright.

Thermoelectric Property Mapping for High‐Performance Integrated MgAgSb‐MgCuSb System To achieve high conversion efficiency in thermoelectric (TE) modules, not only thermoelectric materials (TEMs) with high figure-of-merit zT but also the optimization of thermoelectric interface materials (TEiMs) is required. For TEMs, enhancing zT relies on increasing power factor PF and lowering thermal conductivity κ, while for TEiMs, high electrical conductivity and κ are essential, which highlights the importance of the integrated design of TEMs and TEiMs. In this work, we select p-type MgAgSb as the object and construct a TE property mapping of the integrated MgAgSb-MgCuSb two-phase system by tuning the Ag/Cu ratio. Based on the thermoelectric property mapping, Ag-rich compositions exhibit superior PF and zT values for TEM, maximized in PF∼21 µW cm<sup>-1</sup> K<sup>-2</sup>, zT = 1.12 for MgAg<sub>0.97</sub>Cu<sub>0.03</sub>Sb. Conversely, Cu-rich composition MgAg<sub>0.05</sub>Cu<sub>0.95</sub>Sb is identified as the optimal TEiM for its low contact resistance and superior carrier and phonon transport properties, reducing energy loss. A two-pair thermoelectric module integrated with n-type Mg<sub>3</sub>(Sb, Bi)<sub>2</sub> is successfully fabricated, yielding a peak conversion efficiency of ∼7.2%, thereby advancing the performance of current Mg-based TE modules. Overall, this study realizes the synergistic optimization of high-performance TE materials and compatible TE interface materials, paving the way for the fabrication of efficient and scalable TE modules.

Prospective ICH Q2(R2)-aligned total-error validation of label-free untargeted proteomics for host cell protein quantification in biotherapeutics Untargeted proteomics enables quantitative determination of host cell proteins (HCPs) in biotherapeutics, yet no workflow has been validated under ICH Q2(R2) for regulated quality control. We report a prospective validation of label-free untargeted proteomics for HCP quantification using a total-error (TE) approach. A stable isotope-labeled whole-proteome standard was spiked into NISTmAb at seven levels (20–80 ng). Four independent assays (198 injections) supported hierarchical replication and one-way random-effects ANOVA variance decomposition with Welch–Satterthwaite adjustment. Dual entrapment analysis demonstrated empirical peptide-level false discovery proportions below 1% at q = 0.01. Deterministic parsimony inference ensured invariant protein-group definition. Weighted least-squares regression (R² = 0.993) identified stable proportional compression with recoveries of 81–85%. Repeatability dominated the variance structure (median CV 2.7%); intermediate precision total SD ranged from 0.69% to 3.81% over the validated range. Accuracy profiles integrating empirical bias with a log– log variance model showed 95% β-expectation and 95/95 content tolerance intervals fully contained within ±30%, with a lower limit of quantification (LLOQ) of 20 ng. Abundance-stratified TE analysis revealed concentration-dependent calibration heterogeneity masked by aggregate-level estimation; stratum-specific β-expectation intervals within ±35% defined an abundance-aware LLOQ of 3.6 ppm (P95 = 3.87 ppm). Robustness under independent search software (FragPipe, CCC = 0.998, LoA ±9%) and cross-platform acquisition (Astral, CCC = 0.980, LoA ±18%) remained within predefined ±30% agreement limits. System suitability criteria were derived empirically from validation performance. This is the first prospective ICH Q2(R2)-aligned validation of untargeted proteomics for HCP quantification, with a statistical framework applicable to other high-dimensional analytical methods requiring regulatory qualification.

Dynamic dielectric permittivity tensor of in-plane hyperbolic van der Waals MoOCl2 and emergent chiral photonic applications Van der Waals (vdW) crystals offer unique opportunities for modern nanophotonic applications owing to their intrinsic anisotropic nature. While most of them exhibit uniaxial anisotropy arising from weak out-of-plane vdW interaction, some of their representative families also exhibit an in-plane biaxial anisotropy. Among the latter, outstand vdW oxychlorides with in-plane axes of a different physical character (metallic or dielectric at optical frequencies). Here, we present accurate dynamic dielectric permittivity tensor components of vdW MoOCl₂ in the ultraviolet (UV) to visible (Vis) spectral region partly covering near-infrared (NIR). Addressing its enormously anisotropic Vis to NIR hyperbolic spectral region optical constants, we further identify another hyperbolicity window of vdW MoOCl2 emerging in UV spectral region, which may potentially unlock rich light-matter interaction effects. Furthermore, we propose an approach towards designing nanoscale handedness preserved Vis light circular polarizers based on twisted helical vdW MoOCl₂ heterostructures. Our findings display that vdW MoOCl₂ provides a highly promising platform not only for hyperbolic, but also for chiral nanophotonic applications. van der Waals force ; Anisotropy ; Nanophotonics ; Permittivity ; Dielectric ; Tensor (intrinsic definition) ; Polarizer ; Photonics ; Dielectric permittivity 2D Materials and Applications ; Metamaterials and Metasurfaces Applications ; Quantum Mechanics and Non-Hermitian Physics

Enhancing Magneto-Optical Performance in LaFeO3 Thin Films via Cubic-Phase Transition Induced by Ce3+/Ti4+ Co-Doping Birefringence, arising from the low-symmetry structure in orthorhombic LaFeO3, limits the observation and utilization of magneto-optical effects. In this study, the pure-phase perovskite-typed La1−xCexFe1−xTixO3/SiO2 thin films were successfully fabricated via radio-frequency magnetron sputtering, where the co-doping of Ce3+ and Ti4+ ions effectively induced a structure transition from orthorhombic to a highly symmetric cubic phase, eliminating birefringence effect and thus reducing optical transmission loss. At the same time, the doped Ce3+ ions also effectively enhanced the magnetic and magneto-optical effects of the system due to their strong spin coupling effect and superexchange interaction with Fe3+ ions. The results show that the cubic-phase La0.5Ce0.5Fe0.5Ti0.5O3/SiO2 thin film exhibits excellent magnetic and magneto-optical performance. Their saturation magnetization reaches 180 emu/cm3 with an in-plane easy magnetic axis. And their magnetic circular dichroic ellipticity |ψF| reaches 3054 degrees/cm.

Antiferroaxial altermagnetism The antiferroaxial state is emerging as an important ferroic order in condensed matter systems. Here, we establish antiferroaxial altermagnetism as a broadly prevalent, generic, and microscopically grounded multiferroic mechanism, in which antiferroaxial counter-rotating distortions both induce altermagnetism and enable its deterministic and reversible switching. Within a unified Landau-theory and symmetry framework, we identify a symmetry-allowed trilinear invariant coupling the antiferroaxial order, the Néel vector, and the altermagnetic order, and derive general symmetry criteria for its occurrence. This coupling locks the induced altermagnetism to the antiferroaxial order, so that reversing the latter reverses the spin splitting and associated time-reversal-odd responses, such as anomalous Hall conductivity. We provide a practical spin group dictionary mapping Néel-vector representations to the resulting $d$-, $g$-, and $i$-wave antiferroaxial altermagnetism, validate the mechanism with ligand-rotation tight-binding models and first-principles calculations, and identify many candidate materials by screening the MAGNDATA and C2DB databases. Our results elevate antiferroaxiality to a universal ferroic control knob for structurally programmable altermagnetic spintronics.

The microendemic Aegla expansa (Aeglidae) survives in highly disturbed micro-basins of southern Chile <i>Aegla expansa</i> was described from an exoskeleton by Jara (1992). The type specimen (holotype) of the species was obtained from the hamlet of La Leonera, approximately six km east of the town of Hualqui in the Biobío region of Chile. Since this find, no further biological information has been generated on this species, and it was even thought to have become Extinct in the Wild. By systematic sampling in the commune (district) of Hualqui, we were able to find populations of <i>A. expansa</i> in many of the district's rivers. In this work, we present the first biological information on the species and assess its phylogenetic position within the genus <i>Aegla</i>.

Observation of Iso-Symmetric Structural and Lifshitz Transitions in Quasi-one-dimensional CrNbSe$_5$ Chalcogenides-rich transition metal compounds host a rich landscape of emergent quantum phenomena that are intimately governed by their quasi-one-dimensional chemical-bonding frameworks and their response to external perturbations such as pressure. Here, we report a pressure-induced iso-symmetric structural transition in the quasi-one-dimensional compound CrNbSe$_5$, in which the electronic ground state is controlled not by symmetry breaking but by a continuous reorganization of local bonding interactions. Applied pressure reversibly tunes CrNbSe$_5$ between semiconducting and semimetallic states, enabling access to low- and high-carrier electronic regimes through direct modulation of metal-chalcogen bonding. High-pressure single-crystal X-ray diffraction directly resolves the evolution of Cr-Se and Nb-Se bond distances, coordination polyhedra, and connectivity, revealing a fully reversible semimetal-semiconductor-semimetal transition driven by gradual yet cooperative bond rearrangements within a preserved crystallographic symmetry. In contrast to chemical substitution, which irreversibly alters composition and introduces disorder, pressure acts as a clean, continuous control parameter that reshapes the bonding landscape without disrupting structural symmetry. These results establish CrNbSe$_5$ as a model system for electronically driven phase switching via tunable chemical bonding, highlighting iso-symmetric bond reorganization as a powerful design principle for pressure-controlled electronic and spintronic functionalities.

Effect of Crystal-to-Detector Distance Variations on Serial Femtosecond Crystallography Data Collected at PAL-XFEL Serial femtosecond crystallography (SFX) using X-ray free electron lasers (XFELs) enables the determination of room-temperature structures of biological macromolecules without radiation damage. The accuracy of detector geometry parameters, including the crystal-to-detector distance (CTDD), is critical for reliable data processing. In SFX experiments, the CTDD may shift during data collection due to changes in the experimental setup or installation of the sample delivery system. Such CTDD variations can affect the quality of SFX datasets; however, their impact has not been fully elucidated in the context of SFX data processing. In this study, we investigated the influence of CTDD variations on SFX datasets collected at Pohang Accelerator Laboratory X-ray Free Electron Laser (PAL-XFEL) with thermolysin, lysozyme, and glucose isomerase crystals processed by four indexing algorithms. At the optimized CTDD, the distribution of unit cell parameters exhibited a Gaussian pattern; however, it became distorted as the CTDD deviated further from the optimal value. Data analysis indicated that the CTDD tolerance for successful data processing and structure determination was approximately ±3–5 mm from the optimized CTDD. These findings provide insight into indexing behavior in SFX data processing at PAL-XFEL and offer practical guidance for improving data processing efficiency.

Remarkably High Effective Mobility of 301 cm2/V·s in 3 nm Ultra-Thin-Body SnO2 Transistor by UV Annealing At an ultra-thin 3 nm SnO<sub>2</sub> channel thickness, a record-high effective mobility (µ<sub>eff</sub>) of 301 cm<sup>2</sup>/V·s, field-effect mobility (µ<sub>FE</sub>) of 304 cm<sup>2</sup>/V·s, and a sharp subthreshold swing (<i>SS</i>) of 201 mV/decade are achieved at a high carrier density (N<sub>e</sub>) of 5 × 10<sup>12</sup> cm<sup>-2</sup>. These excellent transport properties are attributed to ultraviolet (UV) light annealing. The resulting µ<sub>eff</sub> is significantly higher than that of Molybdenum Disulfide (MoS<sub>2</sub>) and Tungsten Diselenide (WSe<sub>2</sub>), and is more than twice that of single-crystalline Si channel transistors at the same quasi-two-dimensional (2D) thickness of 3 nm (equivalent to five monolayers of MoS<sub>2</sub>). UV annealing not only enhances µ<sub>eff</sub> and µ<sub>FE</sub> but also sharpens the <i>SS</i>, which is crucial for low-power operation. This improved <i>SS</i> is attributed to reduced scattering from charged interface traps, as supported by µ<sub>eff</sub>-N<sub>e</sub> analysis, thereby increasing the transistor's mobility. The realization of such high-mobility devices at a quasi-2D thickness of only 3 nm is of particular importance for the further downscaling of ultra-thin-body transistors for high-speed computing and monolithic three-dimensional (M3D) integration. Furthermore, the wide bandgap of SnO<sub>2</sub> (3.7 eV) enables operation at relatively high voltages, paving the way for pioneering ternary logic applications.
