Preparation and Properties Study of One-Part Additive Curing Silicone Composites Applying in Advanced Packaging In 2.5D/3D stacked advanced packaging, one-part additive curing silicone composites are widely employed to achieve structural bonding and efficient heat dissipation. In this study, a thermally conductive silicone adhesive was prepared using medium viscosity vinyl silicone oil, hydrogen containing silicone oil, and micron-sized alumina powder as the primary components. The results demonstrated that the adhesive exhibited excellent thermal and mechanical performance. Specifically, its thermal decomposition temperature exceeded 400 °C, the thermal conductivity reached over 1.80 W·m⁻¹·K⁻¹, and the thermal resistance was below 12.0 °C·cm²·W⁻¹. The shear strength exceeded 5.00 MPa. Furthermore, after exposure to uHAST for 384 h, 1,000 thermal cycles, and thermal aging for 1,000 h, the adhesive maintained stable thermal conductivity and mechanical properties. The thermal conductivity remained above 1.70 W·m⁻¹·K⁻¹, and the shear strength remained higher than 5.00 MPa. In addition, the tensile modulus was maintained below 100 MPa, and the coefficient of linear thermal expansion was less than 160 ppm·°C⁻¹. Overall, the comprehensive performance of the adhesive satisfies the reliability requirements for advanced packaging substrates and heat dissipation lid assemblies.

Post-translational modifications of silk proteins Post-translational modifications (PTMs) endow silk proteins with chemical diversity that governs their higher-order assembly, hydration, and covalent connectivity. This review highlights the principal PTMs that define silk protein function, including hydroxylation, glycosylation, phosphorylation, and covalent crosslinking. We also describe their contributions to protein structural stability and mechanical properties. Recent advances in proteomics have begun to reveal low-abundance PTMs, whereas synthetic biology and bioorthogonal chemistry enable the programmed installation of modifications to tune physicochemical properties. Understanding and harnessing these chemistries provides a foundation for the predictive design of next-generation protein-based materials at the interface of chemical biology and materials science.

Metastable twin boundary mediating superelasticity and ferroelasticity in monolayer group IV monochalcogenides Abstract Although covalent and ionic inorganic semiconductors have traditionally been excluded from exhibiting superelastic behavior, recent atomic-scale high-resolution transmission electron microscopy has revealed superelasticity in bulk group-IV monochalcogenides (e.g., GeSe). In this study, we extend the concept of superelasticity to the two-dimensional (2D) atomic limit using ab initio simulations, with GeSe serving as a paradigmatic example. Under uniaxial tensile strain under zigzag direction, resonant-bonding-induced transverse phonon softening is activated, triggering a reversible structural transition mediated by metastable twin boundary—an essential characteristic that distinguishes superelasticity from ferroelasticity. Through systematic analysis, we identify GeSe, SnS, and GeS as promising superelastic candidates, while SnSe, Bi, and Sb exhibit ferroelastic behavior under similar zigzag tensile strain. Additionally, we demonstrate that uniaxial compressive strain along the armchair direction universally induces ferroelasticity in Bi, Sb, GeSe, SnS, and SnSe. These findings not only confirm the existence of superelasticity in 2D materials but also establish a clear criterion for differentiating superelasticity from ferroleasticity. This work provides a transformative framework for understanding and designing flexible electronic devices based on superelastic monolayer group-IV monochalcogenides.

Carbon quantum dots as transcutaneous drug carriers: mechanisms, challenges and prospects Incorporation of nanoparticles has revolutionized drug delivery by optimizing the targeted transport of drugs, boosting the solubility and stability of pharmaceuticals, and facilitating precise, controlled release. These breakthroughs have made a significant contribution, especially in personalized medicine for many health issues. A variety of nanoparticles, including lipid-based systems, polymeric carriers, dendrimers, metallic nanoparticles, and nanogels, have been employed in drug delivery to improve drug solubility, protect active compounds from degradation, and achieve controlled release. Quantum dots are zero dimensional nanoparticles distinguished by intrinsic fluorescence, in particular carbon quantum dots allow for real-time imaging, superior biocompatibility, and antimicrobial properties rendering them highly adaptable for sophisticated therapeutic and diagnostic uses. Transcutaneous drug delivery devices offer a non-invasive approach for administering medications through the skin, enabling drugs to bypass the gastrointestinal tract and first-pass metabolism thereby improving bioavailability, and promoting enhanced patient compliance. Nanoparticles, particularly those sized between 1 and 10 nm in all dimensions, significantly enhance skin penetration, thereby improving drug delivery to deeper tissues, thus making carbon dots an ideal candidate as a nanocarrier in the transcutaneous system. A focused review on carbon quantum dots as novel nanocarriers to overcome present obstacles in transcutaneous drug administration is critically presented.

Characterization of Sequence Distributions in Random and Semi-Random Copolymers We report a strategy for analyzing and distinguishing the sequence distributions of random and semirandom poly-(lactic-<i>co</i>-glycolic acid) (PLGA) analogs using selective digestion at cleavable olefin-containing monomer units. Semirandom copolymers were synthesized via a parallel-successive (P-S) approach that enables coarse-grained sequence control by coupling telechelic oligomers of varied composition and length. Following cross-metathesis digestion, the resulting fragment distributions were fractionated and analyzed via NMR, SEC, and MALDI-MS. These postdigestion data directly reflect the microstructural arrangement of the cleavable units in the predigestion copolymers. Monte Carlo simulations were employed to model both random and P-S copolymerizations, offering in silico digestion data that elucidate the influence of oligomer feed ratios and dispersity on the resulting block-length distributions. Experimental and simulated results demonstrate that P-S copolymers exhibit broader and sometimes bimodal fragment distributions compared to their random analogs, validating the method's capacity to encode and detect distinct microstructural features. This approach provides a scalable, analytically tractable platform for tuning and characterizing sequence distributions in degradable polyesters and potentially other polymer systems where sequence plays a critical role in material properties.

Self-assembly of quasicrystals under cyclic shear We investigate the self-assembly of two-dimensional dodecagonal quasicrystals driven by cyclic shear, effectively replacing thermal fluctuations with plastic rearrangements. Using particles interacting via a smoothed square-shoulder potential, we demonstrate that cyclic shearing drives initially random configurations into ordered quasicrystalline states. The resulting non-equilibrium phase diagram qualitatively mirrors that of thermal equilibrium, exhibiting square, quasicrystalline, and hexagonal phases, as well as phase coexistence. Remarkably, the shear-stabilised quasicrystal appears even where the zero-temperature equilibrium ground state favours square-hexagonal coexistence, suggesting that mechanical driving can stabilise quasicrystalline order in a way analogous to entropic effects in thermal systems. The structural quality of the self-assembled state is maximised near the yielding transition, even though the dynamics are slowest there. Yet, the system still quickly forms monodomain quasicrystals without any complex annealing protocols, unlike at equilibrium, where thermal annealing would be required. Finite-size scaling analysis reveals that global orientational order decays slowly with system size, indicative of quasi-long-range order comparable to equilibrium hexatic phases. Overall, our results establish cyclic shear as an efficient pathway for the self-assembly of complex structures.

The Sensor Modules of a Dedicated Automatic Inspection System for Screening Smoked Sausage Coloration The external color of smoked sausages is a critical indicator of quality and uniformity in processing. Commercial colorimeters are unsuitable for high-throughput sorting due to the challenges posed by the sausage's curved cylindrical surface and the need for an inline application. This study introduces a novel non-contact sensing module (LEDs at 45°, fiber optic collection at 0°) to acquire spectral data (400-700 nm) and derive CIE LAB. First, a handheld prototype validated the accuracy of the sensing module against a benchtop spectrophotometer. It successfully categorized five color grades ('Over light', 'Light', 'Standard', 'Dark', and 'Over dark') with a clear distribution on the a*-L* diagram. This established acceptable color boundary conditions (44.2 < L* ≤ 61.3, 14.1 < a* < 23.9). Second, three sensing modules were integrated around a conveyor belt at 120° intervals, forming the core of an automated inline sorting system. Blind field tests (<i>n</i> = 150) achieved high sorting accuracies of 95.3-97.3% with an efficient inspection time of less than 2 s per sausage. This work realizes the standardization, digitalization, and automation of food color inspection, demonstrating strong potential for smart manufacturing in the processed meat industry.

Robust (n,m) Assignment of Single-Walled Carbon Nanotubes from Electron Diffraction Patterns via Near-Neighbor Search and Cross-Check Correction The chirality (n,m) of single-walled carbon nanotubes (SWCNTs) strongly influences their properties and growth behavior, creating a need for accurate and reproducible evaluation methods. Nanobeam electron diffraction (NBED) is a powerful approach for (n,m) assignment, but practical analysis is often affected by analyst-dependent steps, manual measurement errors, and sample tilt. Here, based on a previously reported calibration-free diffraction analysis framework, we developed a practical SWCNT chirality-assignment protocol that combines near-neighbor (n,m) search with cross-check correction under assumed manual measurement errors and tilt. Feature extraction and candidate screening were semi-automated using an ImageJ script and an Excel VBA macro, thereby reducing analysis time, improving reproducibility, and minimizing operator dependence. Using 2394 simulated NBED images covering CNT diameters of 0.4–2.3 nm, chiral angles of 0–30°, and tilt angles of 0.5–16.5°, with added noise, direct electron beam intensity, and beam-stop effects, the assignment accuracy improved from 71.6% for conventional TRUNC-based analysis to 97.7% with the proposed protocol. Errors in mean CNT diameter, mean chiral angle, and metallic CNT fraction were also nearly eliminated. The substantial improvement in assignment accuracy was primarily attributable to the newly introduced overlap ratio, which effectively reduced the ambiguity and instability present in the initial candidate discrimination.

Insights into gaseous hydrogen permeation behavior in welds of X65 pipeline steel Abstract This study compares the gaseous hydrogen permeation behavior of API 5L X65 pipeline steel welds produced using hybrid laser–arc welding (HLAW) and gas metal arc welding (GMAW). Electron backscatter diffraction (EBSD) and high-pressure hydrogen permeation tests were used to evaluate the grain boundary characteristics and hydrogen diffusion in the welds. The HLAW weld displayed a finer microstructure with a higher fraction of high-angle grain boundaries (HAGBs) compared to the GMAW weld. This resulted in a lower effective hydrogen diffusion coefficient (3.13 × 10⁻ 6 cm 2 /s) and a higher surface hydrogen concentration (6.63 × 10⁻ 12 mol/cm 3 ) in the HLAW specimen. Thermal desorption spectroscopy (TDS) further revealed higher hydrogen accumulation due to stronger hydrogen trapping associated with HAGBs in the HLAW welds, which are formed by the rapid cooling inherent to this welding technique. These results show that enrichment of HAGBs effectively hinders hydrogen diffusion. Therefore, optimizing weld design using HLAW can reduce hydrogen permeation in pipeline steels intended for hydrogen transport applications.

Mechanistic insights into the color transformation of a non-FRET substrate for RNase activity detection DNA-templated silver nanoclusters (DNA/AgNCs) have created a new class of non-FRET DNase substrates, termed Subak, that exhibits a color change upon DNase digestion. Although Subak substrates offer advantages such as ratiometric readouts and low manufacturing costs over traditional FRET substrates, the mechanism governing AgNC color switching remains unclear. Here, using a site-specific cleavage strategy, we identify color-switching hotspots and demonstrate that AgNC transformation can be controlled by the cleavage positions within the nucleic acid host. Our data support a cleavage-driven reorganization of the AgNC coordination environment, converting a non-emissive precursor into a red-emitting cluster, rather than direct enzyme-cluster interactions. Leveraging this insight, we engineer rSubak, an RNA-incorporated Subak that displays 95 nm red shift (530 to 625 nm) upon RNase cleavage. In amplification-free CRISPR/Cas13 assays for SARS-CoV-2, influenza A (A/H5N1), and measles viruses (MV) detection, rSubak achieved a limit of detection of 0.3 pM, superior to that of the commercial RNaseAlert (∼250 pM). Collectively, our results establish Subak as a generalizable, non-FRET platform for sensitive ratiometric reporting the activities of diverse nucleases.

Compounds <b>9</b> and <b>17</b> exhibited the most promising antiproliferative activity against TNBC cell lines (MDA-MB-468: IC<sub>50</sub> = 36.62 µM for <b>9</b> and 38.29 µM for <b>17</b>; MDA-MB-231: IC<sub>50</sub> = 37.32 µM for <b>9</b> and 32.86 µM for <b>17</b>; Hs578T: IC<sub>50</sub> = 57.26 µM for <b>9</b> and 34.87 µM for <b>17</b>), while maintaining acceptable selectivity toward non-cancerous cells. The lead compounds were further assessed in vivo using a <i>Danio rerio</i> model to evaluate general toxicity and cardiotoxicity. In addition, ADME parameters were predicted for all compounds using biomimetic chromatography. Overall, compounds <b>9</b> and <b>17</b> emerged as promising small-molecule candidates for TNBC treatment, requiring further toxicological evaluation in more human-relevant in vivo models.
