Precise and reproducible control of polymer molecular-weight distributions, especially weight-average molecular weight (Mw) and dispersity (Ð), remains a major challenge for semiconducting polymers. Here, we introduce a two-dimensional Mw–Ð space that reformulates distribution engineering as a coordinate-based design problem. Extending two-batch to three-batch mixing (x + y + z = 1) expands accessible distributions from a one-dimensional trajectory to a continuous two-dimensional surface, enabling independent tuning of Mw and Ð within the batch-defined feasible region. Experiments using representative semiconducting polymers validate the framework by reproducing target Mw–Ð coordinates with errors below 4.4%. Machine learning maps performance across Mw–Ð space, where direct power-conversion-efficiency (PCE) prediction outperforms reconstruction from photovoltaic parameters. This framework enables direct PCE prediction without decomposing interdependent properties governing device performance. Inverse design achieves high PCEs with <0.15% deviation, surpassing the original batch limit. The batch-defined Mw–Ð framework enables practical molecular-weight-distribution optimization in semiconducting polymers.
聚合物分子量分布的精确和可重复性控制,特别是重量-平均分子量(Mw)和分散性(Ð),仍然是半导体聚合物的主要挑战。在这里,我们引入一个二维Mw -Ð空间,将配电工程重新表述为一个基于坐标的设计问题。将两批混合扩展到三批混合(x + y + z = 1)将可访问分布从一维轨迹扩展到连续的二维表面,从而可以在批定义的可行区域内独立调整Mw和Ð。使用代表性半导体聚合物的实验通过再现目标Mw -Ð坐标来验证该框架,误差低于4.4%。机器学习映射了Mw -Ð空间的性能,其中直接功率转换效率(PCE)预测优于光伏参数重建。该框架可以直接预测PCE,而无需分解控制设备性能的相互依赖属性。反设计实现了pce <0.15%的高偏差,超过了原批次限制。批量定义的Mw -Ð框架使半导体聚合物中的实际分子量分布优化成为可能。

The use of biomolecules for degradable plastics is key to a sustainable plastics industry. However, current biomolecule-based plastics are often brittle or rely on nondegradable crosslinkers, limiting their practicality. Inspired by natural biominerals, we crosslinked bovine serum albumin (BSA) and sodium alginate (SA), using calcium phosphate oligomers (CPO), to form a biomineral (BSA/SA/CPO; abbreviated as BSC) plastic. Unlike traditional crosslinking, CPO undergo ionic polymerization within the biomolecular network to form flexible hydroxyapatite nanowires, which establish hydrogen bonding and ionic-crosslinking networks with BSA/SA chains. This gives BSC mechanical properties comparable to conventional plastics, along with flame retardancy, solvent resistance, and degradability. BSC can be ingested by land and marine organisms, enter natural matter cycles through digestion, and pose minimal anticipated risks. Thus, BSC is a promising candidate for replacing certain polymers and reducing plastic pollution. This strategy can be extended to various biomolecular systems, paving the way for a green plastics industry.
生物分子在可降解塑料中的应用是塑料工业可持续发展的关键。然而,目前基于生物分子的塑料通常很脆或依赖于不可降解的交联剂,限制了它们的实用性。受天然生物矿物的启发,我们利用磷酸钙低聚物(CPO),将牛血清白蛋白(BSA)和海藻酸钠(SA)交联,形成生物矿物(BSA/SA/CPO,简称BSC)塑料。与传统的交联不同,CPO在生物分子网络内进行离子聚合,形成柔性羟基磷灰石纳米线,从而与BSA/SA链建立氢键和离子交联网络。这使得BSC的机械性能与传统塑料相当,同时具有阻燃性、耐溶剂性和可降解性。平衡计分卡可以被陆地和海洋生物吸收,通过消化进入自然物质循环,并构成最小的预期风险。因此,平衡记分卡是替代某些聚合物和减少塑料污染的有希望的候选者。这一策略可以扩展到各种生物分子系统,为绿色塑料工业铺平道路。

Soft magnetoelastic materials and bioelectronics are emerging as transformative paradigms in personalized healthcare and sustainable energy. However, the physical origin of giant magnetoelasticity in soft material systems remains insufficiently understood, limiting material design and optimization. Here, we develop a continuous-fiber model for giant magnetoelasticity in soft matter by mapping the wavy-chain architecture onto an equivalent virtual continuous-fiber representation, which transforms a complex particulate system into a tractable analytical description. Within this framework, the anisotropic mechanical behavior of particulate-reinforced magnetoelastic materials is recast as an equivalent transversely isotropic, fiber-reinforced constitutive description. The model captures the essential mechanics imparted by the wavy-chain microstructure, while enabling concise, closed-form analysis of magnetoelastic coupling. Building on this framework, we further introduce microstructure-informed optimization strategies. Overall, this work establishes a quantitative and scalable framework for understanding and optimizing giant magnetoelasticity in soft matter.
软磁弹性材料和生物电子学正在成为个性化医疗保健和可持续能源的变革范例。然而,软材料系统中巨磁弹性的物理起源仍然没有得到充分的了解,这限制了材料的设计和优化。在这里,我们通过将波链结构映射到等效的虚拟连续纤维表示上,开发了软物质巨磁弹性的连续纤维模型,该模型将复杂的粒子系统转换为可处理的分析描述。在此框架内,颗粒增强磁弹性材料的各向异性力学行为被重铸为等效的横向各向同性,纤维增强本构描述。该模型捕捉了波浪链微观结构所赋予的基本力学,同时实现了简洁、封闭的磁弹性耦合分析。在此框架的基础上,我们进一步介绍了微结构优化策略。总的来说,这项工作为理解和优化软物质的巨磁弹性建立了一个定量和可扩展的框架。

The environmental threat of petroleum-based plastics drives demand for sustainable alternatives, yet biodegradable materials often fail in humid conditions due to hydrophilicity and weak interfaces. Here, inspired by brick-and-mortar structure of mussel shells and interfacial adhesion mechanisms of mussel byssus, a dual bioinspired strategy is reported that leverages a thermal activation at 150°C to trigger in situ interfacial curing within an intrinsic network of pollen, cellulose, and chitosan. This process yields a hierarchically organized biocomposites with outstanding mechanical performance (tensile strength, 98.55 MPa; wet tensile strength, 77.30 MPa) and enables binder-free shaping into complex structures ranging from flexible films to rigid bulk materials. Notably, the biocomposites also exhibit superior barrier performance compared with representative biodegradable polymers, featuring low water vapor permeability (∼41.11 ± 4.87 g·m−2·day−1), oxygen permeability (∼3.31 ± 0.33 cm3·m−2·day−1), and efficient ultraviolet shielding (UV absorption > 99.8%). This work offers a green, scalable route to high-performance sustainable biocomposites with integrated functionality.
石油基塑料对环境的威胁推动了对可持续替代品的需求,但由于亲水性和弱界面,可生物降解材料往往在潮湿条件下失效。在这里,受贻贝壳的砖和砂浆结构和贻贝足的界面粘附机制的启发,报道了一种双重生物激发策略,利用150°C的热激活来触发花粉、纤维素和壳聚糖内在网络中的原位界面固化。该工艺生产出具有优异机械性能的分层组织生物复合材料(抗拉强度,98.55 MPa;湿抗拉强度,77.30 MPa),并且可以在无粘合剂的情况下成型成复杂的结构,从柔性薄膜到刚性体材料。值得注意的是,与代表性的生物可降解聚合物相比,生物复合材料还表现出优越的屏障性能,具有低水蒸气渗透性(~ 41.11±4.87 g·m−2·day−1),氧渗透性(~ 3.31±0.33 cm3·m−2·day−1)和有效的紫外线屏蔽(UV吸收> 99.8%)。这项工作为具有集成功能的高性能可持续生物复合材料提供了一条绿色、可扩展的途径。

Lignin-based carbon fiber offers a sustainable and cost-effective alternative to petroleum-derived products, yet research has failed to achieve commercially relevant performance. We demonstrated crystallite orientation enhancement as a new strategy to improve performance. Functionalized single-walled carbon nanotubes (F-SWCNTs) were introduced as a crystallization inducer, followed by external stress-guided structure adjustment and carbonization optimization. The resulting carbon fiber exhibited an increased crystallite orientation that substantially improved mechanical performance and electrical conductivity. Further analysis confirmed that the incorporation of F-SWCNTs significantly enhanced the structural integrity and crystallite orientation when tension application and carbonization temperature were co-optimized. The industrially relevant wet-spun lignin-based carbon fiber achieved a tensile strength of 2.04 GPa and an elastic modulus of 176 GPa, surpassing the automotive industry application standard. Techno-economic and life cycle analyses indicated substantial potential to reduce cost and environmental footprint. The study revealed critical design principles for high-quality materials and enabled a sustainable path for lightweight materials.
木质素基碳纤维为石油衍生产品提供了一种可持续且具有成本效益的替代品,但研究未能实现与商业相关的性能。我们证明了晶体取向增强是提高性能的新策略。引入功能化单壁碳纳米管(F-SWCNTs)作为结晶诱导剂,然后进行外部应力引导结构调整和碳化优化。由此产生的碳纤维显示出增加的晶体取向,大大提高了机械性能和导电性。进一步分析证实,当张力施加和碳化温度共同优化时,F-SWCNTs的掺入显著增强了结构完整性和晶体取向。工业相关湿纺木质素基碳纤维的抗拉强度为2.04 GPa,弹性模量为176 GPa,超过汽车工业应用标准。技术经济和生命周期分析表明,降低成本和环境足迹的潜力巨大。该研究揭示了高质量材料的关键设计原则,并为轻质材料开辟了一条可持续发展的道路。

In this study, we report a novel single-atom nanozyme (SAzyme) architecture characterized by unique dual-active sites comprising IrN4Cl single atoms adjacent to IrO2−x nanoclusters within a zirconium-based metal-organic framework (MOF). Combined with pore-wall engineering via electron-withdrawing –NO2 groups, the resulting Zr–TCPP(Ir)/IrO2−x–NO2 MOF SAzyme redirects the H2O2 activation pathway from the conventional homolytic cleavage that produces hydroxyl radicals to a heterolytic cleavage that selectively generates singlet oxygen (1O2) (H2O2→∗OOH→∗OO→1O2), overcoming the kinetic limitations of homolytic pathways. Experimental and theoretical calculations reveal that the strong electronic coupling between the spatially proximate IrN4Cl and IrO2−x pair, combined with electron-withdrawing –NO2 groups, optimally modulates the Ir electronic state and stabilizes key ∗OOH intermediates. Consequently, the designed SAzyme exhibits a specific activity of 1,258 U/mg, about 88 times that of Fe-N4 MOF nanozymes and 3.62 times that of horseradish peroxidase, marking the highest value reported to date for single-atom catalysts.

Lithium-sulfur batteries suffer from sluggish sulfur redox reactions and lithium polysulfide (LiPS) shuttling. Here, we develop oxygen-doped molybdenum diselenide (O-MoSe2) as a multifunctional sulfur host with electronically engineered trap states. Aberration-corrected STEM, EPR, and XAFS reveal abundant Se vacancies and Mo-O coordination, evidencing defect-dopant-induced local electronic reconstruction. DFT calculations show that oxygen doping lowers the occupation of Mo 4d antibonding eg orbitals toward a near-half-filled configuration, creating complementary deep and shallow trap states. Deep traps promote electron transfer and Li2S decomposition, whereas shallow traps strengthen LiPS anchoring through Mo–S and Se–Li interactions. In situ Raman and DRT analyses confirm accelerated LiPS conversion and sulfur redox kinetics. Consequently, O-MoSe2/S cathodes retain 480 mAh g−1 after 1,000 cycles at 1C, deliver 660 mAh g−1 at 5C, and operate stably from 0°C to 60°C.
锂硫电池存在硫氧化还原反应缓慢和锂多硫化物(LiPS)穿梭的问题。在这里,我们开发了氧掺杂二硒化钼(O-MoSe2)作为具有电子工程陷阱态的多功能硫宿主。像差校正后的STEM、EPR和XAFS显示了丰富的Se空位和Mo-O配位,证明了缺陷掺杂引起的局部电子重建。DFT计算表明,氧掺杂降低了mo4d反键eg轨道的占据,使其接近半填充构型,形成了互补的深阱和浅阱态。深阱促进电子转移和Li2S分解,而浅阱通过Mo-S和Se-Li相互作用加强LiPS的锚定。原位拉曼和DRT分析证实了lip转化和硫氧化还原动力学的加速。因此,O-MoSe2/S阴极在1C下循环1000次后保持480 mAh g - 1,在5C下提供660 mAh g - 1,并在0°C至60°C范围内稳定工作。

Morphological evolution across multiple timescales, sustained by spatiotemporally evolving reactive species (STERS), underpins living systems’ development and adaptation. However, synthetic materials rarely recapitulate such evolving morphodynamics. Here, we propose a novel strategy that enables life-like generation of STERS, programming hydrogel morphological evolution across micro- to macro-scales and over minutes to weeks. This STERS system integrates gallium-based liquid metal particles, vinyl monomers, and near-infrared (NIR) light to establish spatiotemporal reactive species gradients for weeks following a single NIR exposure. STERS drive progressive free radical polymerization and ionic complexation, generating spatiotemporally evolving crosslinking gradients and enabling programmable shape transformations. We further extend these morphology-evolving hydrogels to biomedical applications, including directing stem cell differentiation and monitoring electroencephalogram signals in the developing brain. These advances pave the way for a new paradigm in the design of next-generation intelligent materials and devices, with promising applications in robotics, regenerative medicine, and brain-machine interfaces.
多时间尺度的形态进化,由时空进化的反应物种(reactive species, STERS)维持,是生命系统发展和适应的基础。然而,合成材料很少再现这种进化的形态动力学。在这里,我们提出了一种新颖的策略,能够生成类似生命的STERS,编程水凝胶形态进化,跨越微观到宏观尺度,几分钟到几周。该STERS系统集成了镓基液态金属颗粒、乙烯基单体和近红外(NIR)光,在单次近红外照射后数周内建立了时空反应物质梯度。STERS驱动渐进的自由基聚合和离子络合,产生时空演变的交联梯度,并实现可编程的形状转换。我们进一步将这些形态进化的水凝胶扩展到生物医学应用,包括指导干细胞分化和监测发育中的大脑中的脑电图信号。这些进步为下一代智能材料和设备设计的新范式铺平了道路,在机器人、再生医学和脑机接口方面有着广阔的应用前景。

Currently, commercial thermoluminescence (TL) dosimeters predominantly employ inorganic doped phosphors, which are commonly plagued by issues such as stringent synthesis conditions and complex preparation processes. In this work, a non-doped TL dosimeter based on copper-cluster-based framework (CuI-TLD) was synthesized via a mild preparation process. The TL spectral integral area of CuI-TLD shows excellent linear response to X-ray doses, with a limit of detection (LOD) as low as 0.014 mGy. In addition, based on the excellent scintillation performance and TL properties of CuI-TLD, an integrated TL dosimetry/X-ray imaging technology was developed, which enables accurate in situ determination of the actual accumulated radiation dose absorbed by an imaged object during X-ray imaging. This work provides a new perspective for development of high-performance TL materials and offers a novel chemometric tool for fields such as radiation-based medical diagnosis and treatment, as well as radiation-based plant breeding.
目前,商用热释光(TL)剂量计主要采用无机掺杂荧光粉,普遍存在合成条件严格、制备工艺复杂等问题。本文通过温和的制备工艺合成了一种基于铜簇基框架(CuI-TLD)的非掺杂TL剂量计。CuI-TLD的TL光谱积分面积对x射线剂量有良好的线性响应,检出限低至0.014 mGy。此外,基于CuI-TLD优异的闪烁性能和TL特性,开发了一种TL剂量学/ x射线成像集成技术,可以准确地原位测定被成像物体在x射线成像过程中实际吸收的累积辐射剂量。这项工作为高性能TL材料的开发提供了新的视角,并为辐射医学诊断和治疗以及辐射植物育种等领域提供了新的化学计量工具。

Chirality governs numerous optical phenomena. Imparting chirality to photonic materials yields diverse chiroptical functions, among which circularly polarized luminescence (CPL) is particularly valuable for advanced optoelectronic and display applications. Cholesteric liquid crystals (CLCs), with long-range helical superstructures, are attractive templates for CPL generation. However, achieving arbitrarily patterned chiral architectures with high luminescence dissymmetry factors remains challenging. Here, we present a large-area-compatible screen-printing strategy for high-fidelity CLC patterns with intense CPL emission. By optimizing ink viscosity and screen-stencil geometry, uniform ≈50 μm CLC patterns are achieved on rigid and flexible substrates. Screen printing facilitates liquid-crystal pre-alignment, while evaporation-induced self-assembly produces highly oriented helical superstructures. Incorporating fluorescent dyes into these chiral templates enables full-color CPL with |glum| up to 1.72. Opposite-handed pixel microarrays demonstrate the stereoscopic 3D display concept through orthogonal polarization channels. This strategy offers a potentially scalable route to patterned CPL architectures for information encryption and next-generation 3D displays.
手性支配着许多光学现象。赋予光子材料手性可以产生多种手性功能,其中圆偏振发光(CPL)在先进的光电和显示应用中特别有价值。具有长程螺旋超结构的胆甾型液晶(CLCs)是生成CPL的有吸引力的模板。然而,实现具有高发光不对称因素的任意图案手性结构仍然具有挑战性。在这里,我们提出了一种大面积兼容的丝网印刷策略,用于具有强烈CPL发射的高保真CLC图案。通过优化油墨粘度和丝网模板几何形状,在刚性和柔性衬底上实现了均匀≈50 μm的CLC图案。丝网印刷有利于液晶预对准,而蒸发诱导的自组装产生高度定向的螺旋上层结构。将荧光染料纳入这些手性模板中,使|glum|高达1.72的全彩CPL成为可能。相反手像素微阵列通过正交极化通道展示了立体3D显示概念。该策略为信息加密和下一代3D显示提供了一种可扩展的模式CPL架构。
