Nanocrystal-in-glass (NIG) is an exciting class of composites, because it can not only combine the advantages of crystal and glass materials but also potentially generate new physical phenomenon in a cooperative manner. Herein, the nonlinear light–matter interaction processes in a broad range of NIG composites homogeneously embedded with LiNbO 3 are investigated. It is shown that, by rational control of the organization manner of crystal and glass phases, second-harmonic generation (SHG) can be precisely tuned. Importantly, an unusual SHG phenomenon, transverse SHG (TSHG), can be realized in the special region of the microstructure map combined with the features of high loading, nanoscale size, and homogenous distribution of nanocrystals. Furthermore, NIG composites exhibit broadband optical response, allowing TSHG in a wide waveband region to be achieved. Based on the above effects, the applications of the constructed NIG composite for precise measurement of the group velocity and duration of ultrashort optical pulses with femtosecond time scales are demonstrated. Indeed, the findings outline a fundamental principle to design NIG configurations for creating new properties, providing new directions for expanding the scope of NIG functional materials.

Coupling the effects of flexoelectricity with piezoelectricity has been proved to effectively harvest mechanical energy. In this study, a composition-graded core–shell structure (HAP@FAP) was prepared by surface-gradient F-doping in hydroxyapatite, which could introduce flexoelectricity by a built-in strain gradient. A flexoelectric-boosted piezoelectric response was demonstrated by piezoresponse force microscopy (PFM) characterization, showing that the piezoelectric constant of HAP@FAP was increased by 2.25 times via a lattice strain gradient induced by chemical heterogeneities derived from the unique composition-graded core–shell structure. Thus, the piezocatalytic activity of HAP@FAP for phenanthrene (PHE) degradation in soil was enhanced. This work provides a new strategy for the modification of piezoelectric catalysts for the remediation of organics-contaminated soils on industrial land.

Volume expansion and polysulfide shuttle effect are the main barriers for the commercialization of lithium-sulfur (Li-S) battery. In this work, we in-situ polymerized a cross-linked binder in sulfur cathode to solve the aforementioned problems using a facile method under mild conditions. Polycarbonate diol (PCDL), triethanolamine (TEA) and hexamethylene diisocyanate (HDI) were chosen as precursors to prepare the cross-linked binder. The in-situ polymerized binder (PTH) builds a strong network in sulfur cathode, which could restrain the volume expansion of sulfur. Moreover, by adopting functional groups of oxygen atoms and nitrogen atoms, the binder could effectively facilitate transportation of Li-ion and adsorb polysulfide chemically. The Li-S battery with bare sulfur and carbon/sulfur composite cathodes and cross-linked PTH binder displays much better electrochemical performance than that of the battery with PVDF. The PTH-bare S cathode with a mass loading of 5.97 mg/cm 2 could deliver a capacity of 733.3 mAh/g at 0.2 C, and remained 585.5 mAh/g after 100 cycles. This in-situ polymerized binder is proved to be quite effective on restraining the volume expansion and suppressing polysulfide shuttle effect, then improving the electrochemical performance of Li-S battery.

Edge structures are highly relevant to the electronic, magnetic, and catalytic properties of two-dimensional (2D) transition metal dichalcogenides (TMDs) and their one-dimensional (1D) counterparts, i.e., nanoribbons, and should be precisely tailored for the desired application. In this work, we report the formation of novel Mo 6 S 6 nanowire (NW)-terminated edges in monolayer molybdenum disulfide (MoS 2 ) via an e–beam irradiation process combined with high temperature heating. The atomic structures of the NW-terminated edges and the dynamic formation process were observed experimentally using scanning transmission electron microscopy. Further analysis showed that the NW-terminated edge could be formed on both the Mo-zigzag (ZZ) edge and S-ZZ edge and could exhibit a stability superior to that of the pristine ZZ and armchair (AC) edges. In addition, analogous edge structures could also be formed in MoS 2 nanoribbons and other TMD materials such as Mo x W 1− x Se 2 . We believe that these novel edge structures may impart novel properties to the 2D and 1D TMD materials and provide new opportunities for their applications in catalytic, spintronic, and electronic devices.

Solid electrolytes, as the core components of all-solid-state batteries, are a prominent research focus due to its lithium-ion rapid diffusion capability. The halide solid electrolyte Li 3 InCl 6 , distinguished by its high ionic conductivity and remarkable moisture reversibility, has garnered considerable attention in the realm of electrochemistry. This study systematically investigates the influence of Li + vacancy defect concentration on lattice configuration and ionic transport properties through In-rich compositional modulation in Li 3 InCl 6 electrolytes with varying Li/In cation ratios. Experimental results reveal that, under an invariant primary lattice framework, increasing In 3+ content induces preferential occupation of the 4 g Wyckoff sites by In 3+ , generating lattice distortion that deforms the cation layer in the (001) crystallographic plane. Concurrently, substantial tetrahedral vacancy defects emerge within the Li + layer of the (002) plane. This synergistic structural evolution markedly enhances lithium-ion transport kinetics by weakening anion framework constraints on Li + migration. Correspondingly, electrochemical characterization demonstrates that the optimized Li 2.55 In 1.15 Cl 6 electrolyte achieves a threefold increase in ionic conductivity compared to the pristine sample. The performance enhancement originates from distorted non-migrating ion sites and generated vacancy defects within the crystal lattice. Consequently, all-solid-state lithium batteries incorporating this optimized electrolyte exhibit significantly improved cycling stability and rate capability. This study prepares Li 3-3x In 1+x Cl 6 via ball milling and investigates the structure-performance relationships through vacancy regulation, demonstrating a viable strategy for solid-state electrolyte design.

In order to evaluate the influence of asphaltene polarity on the behaviors of hydrates, four subfractions with different polarities fractionated from asphaltenes are used for hydrate nucleation, growth, and dissociation experiments. It is found that the subfraction with higher polarity shows a higher self-aggregate tendency in emulsions and tends to adsorb less at the oil–water interface, which is mainly caused by its larger C/H ratio and higher aromaticity. The addition of asphaltenes increases the induction time of hydrates, and this effect is strengthened in the emulsion with the less polar subfraction. The calculation results of total gas consumption indicate that the amount of formed hydrate decreases with the increase of asphaltenes, especially in the emulsion with the higher polarity subfraction. Moreover, asphaltene subfractions are observed to accelerate the dissociation process of hydrates.

Surface-enhanced Raman spectroscopy (SERS) has achieved extensive applications through carefully engineered plasmonic metasurfaces. Disordered plasmonic metasurfaces are widely used for SERS applications due to their simple fabrication and low cost. However, their poor spatial uniformity usually causes severe signal fluctuations, degrading the repeatability and robustness of SERS measurements. We propose an order-in-disorder metasurface to address this challenge. The design relies on regulating the degree of disorder by introducing a controlled level of ordered features, facilitating the orderly manipulation of photonic Anderson localization. As a representative proof-of-concept example, we fabricate a flexible plasmonic nanoflower-like metasurface by a cost-effective process and each nanoflower contains randomly distributed nanosheets. Compared with the traditional disordered metasurface, it shows competitive SERS signal intensities while dramatically reducing the relative standard deviation (RSD). In detecting trace pesticide residues on fruit surfaces, this metasurface exhibits a low RSD. The enhanced robustness stems from the strong electromagnetic coupling between short-range disordered states of Anderson localization and long-range ordered plasmonic polaritons. The disordered states provide great near-field enhancement, while the ordered mode manipulates hotspot uniformity. This scheme supports the development of a low-cost, high-repeatability, versatile SERS metasurface, and will inspire more practical agriculture and supply chain applications.

Intellectual disability (ID) is a common neurodevelopmental disorder that severely affects cognitive function and social adaptability. Although its pathogenic factors are complex and diverse, genetic causes—particularly de novo variants—play a critical role in sporadic cases. Here we identified two de novo variants in the MAGED1 (Melanoma-Associated Antigen D1) in two independent ID families: a frameshift variant (NM_001005332.2: c.410dupT, Leu137PhefsTer4) and a missense variant (NM_001005332.2: c.932 A > G, Gln311Arg). Functional experiments revealed distinct molecular mechanisms by which these variants may contribute to ID pathogenesis. Our co-immunoprecipitation and immunofluorescence studies indicated that Leu137PhefsTer4 variant disrupted the interaction between MAGED1 and the E3 ubiquitin ligase Praja-1, impairing the degradation of the truncated variant protein and leading to its abnormal stabilization and elevated expression which proven by Western blot. Additionally, wound healing and transwell migration assays revealed Leu137PhefsTer4 abolished the wild-type (WT) MAGED's inhibitory effect on HeLa cell migration, suggesting potential interference with normal neuronal migration. In contrast, by detecting the cell cycle and apoptosis, we found that Gln311Arg variant significantly dysregulated apoptosis and cell cycle progression compared to the WT, implicating its role in disrupting neurodevelopmental homeostasis. Our findings establish a link between MAGED1 de novo variants and ID, expanding the genetic spectrum of ID. These results further highlight the critical role of MAGED1 in neurodevelopment and open new avenues for investigating the pathological mechanisms of ID.

Carbon capture with chemical absorption method represents a critical pathway toward carbon neutrality in industry. However, its application faces challenges including high capture energy requirement for CO 2 desorption and limited CO 2 utilization routes. This study employed diethanolamine (DEA) as a CO 2 absorbent to prepare CO 2 –absorbed DEA (termed DEA–CO 2 ) with different CO 2 absorption amount. DEA–CO 2 was employed to modulate cement strength development, bypassing the energy-intensive CO 2 desorption step. Effects of DEA–CO 2 on cement hydration and the microstructure of the hardened cement pastes were investigated to reveal the regulation mechanism by in-situ carbonation. Results demonstrate that DEA-CO 2 additions show the potential to enhance 3d and 28d strength. Optimal performance occurs with 0.15% DEA and 0.22% CO 2 (D0.15%C0.22%), elevating 3d and 28d compressive strength by 15.3% and 29.3%, respectively. The enhancement is attributed to the accelerated hydration of aluminates and silicates by DEA–CO 2 to achieve a more condensed structure. Moreover, carbonation in cement pastes by DEA–CO 2 effectively mitigates the retardation effect of 0.15% DEA on early cement hydration. However, in the presence of DEA–CO 2 , the accelerated reaction of C 3 A with gypsum delays C 3 S hydration, especially for D0.15%C1.32%. It is hypothesized that the precipitated CaCO 3 or CaCO 3 –AFm on the surface of cement particles also inhibits further silicates hydration. Therefore, D0.15%C1.32% reduces the compressive strength before 28d. These results confirm the potential of utilizing DEA–CO 2 without desorption to optimize the strength development of cementitious materials, provided that the CO 2 dosage is carefully controlled.

Li 2 CO 3 was introduced into LiPF 6 -based electrolytes and the electrolytes were stored at 40 °C. Nuclear magnetic analysis of electrolytes and X-ray diffraction characterization of reaction residues demonstrate the formation of LiPO 2 F 2 and LiF during storage. This reformulated electrolyte boosts lifespan and Coulombic efficiency (CE) in Li||Li and Li||Cu cells, with Li||Li cells stably cycling for >800 h and 300 h at 0.5 mA/cm 2 and 1.0 mA/cm 2 , respectively. Moreover, with the optimal content of Li 2 CO 3 , the CE of the reformulated electrolyte (91.56%) is greatly improved compared to that of the standard electrolyte (81.99%). The compatibility and enhanced rate performance of the reformulated electrolyte are also exhibited in Li||NCM full cells with a moderately high mass loading of 9.6 mg/cm 2 .

In order to induce esophageal muscle cells’ orientation, the silicon wafer with prototype 1 and prototype 2 was designed. Prototype 1 has micro-channels of 200 µm width and 30 µm depth with 30 µm wide wall as the interval. Prototype 2 has channels of 100 µm width and 30 µm depth with a discontinuous wall which has 30 µm gap for each 100 µm channel. The poly(ester urethane) scaffolds with pattern prototype 1 and prototype 2 were fabricated using solution casting method and abbreviated as PU1 and PU2, respectively. Silk fibroin was grafted individually on PU1 and PU2 surface (PU1-SF, PU2-SF) using our previous protocol, aiming at improving scaffolds’ biocompatibility. The primary esophageal smooth muscle cell was seeded to evaluate the scaffolds’ cytocompatibility in vitro. Characterizations like MTT assay, immunocytochemistry, scanning electron microscope, and Western blotting were applied. After that, poly(ester urethane) scaffolds with double patterns, prototype 1 on the exterior, and prototype 2 in the lumen were implanted into the rabbit esophagous to test the regeneration of the muscle tissue. Results from these preliminary tests showed that the growth and differentiation of primary smooth muscle cells were promoted, but also the muscle tissue with endocircular and exolongitudinal architecture was in regenerating, against non-constitution in the animals without the patterned scaffold or with poly(ester urethane) plane membrane at the defaulted sites. This micro-channel pattern together with silk fibroin grafting and vascular endothelial growth factor coating greatly promoted the regeneration of esophageal muscle with normal histological structure.
