Coxsackievirus B3 (CVB3) is a member of the enterovirus genus and linked to several diseases, including myocarditis, which can progress to dilated cardiomyopathy. Despite ongoing preclinical efforts, no clinically approved vaccines against CVB3 are currently available, highlighting the urgent need for effective prophylactic solutions. In this study, a nanovaccine platform based on spider minor ampullate silk protein (MiSp) is introduced. This platform utilizes protein nanoparticles engineered from chimeric proteins that incorporate CVB3 antigenic peptides into customized MiSp, subsequently loaded with all‐trans retinoic acid (RA). These functional nanovaccines are capable of eliciting both mucosal and systemic immune responses following subcutaneous administration and demonstrate significant protective effects against CVB3 infection in mice. This study signifies an approach in peptide‐based parenteral vaccine strategies, utilizing engineered MiSp nanoparticles combined with RA. This methodology represents a promising pathway for preventing enterovirus infections by leveraging the unique immunomodulatory properties of spidroins and RA to combat these pathogens effectively.

柯萨奇病毒 B3（CVB3）是肠道病毒属的一种，与包括心肌炎在内的多种疾病有关，心肌炎可发展为扩张型心肌病。尽管临床前研究一直在进行，但目前还没有获得临床批准的 CVB3 疫苗，因此迫切需要有效的预防性解决方案。在本研究中，介绍了一种基于蜘蛛小安培蚕丝蛋白（MiSp）的纳米疫苗平台。该平台利用嵌合蛋白制成的蛋白质纳米颗粒，将 CVB3 抗原肽纳入定制的 MiSp，然后再加入全反式维甲酸（RA）。这些功能性纳米疫苗经皮下注射后能引起粘膜和全身免疫反应，对小鼠感染 CVB3 有显著的保护作用。这项研究标志着一种基于肽的肠外疫苗策略，即利用工程化 MiSp 纳米颗粒与 RA 结合。这种方法是一种很有前景的预防肠道病毒感染的途径，它利用了刺鞘氨醇和 RA 的独特免疫调节特性来有效对抗这些病原体。

Alkaline Water Electrolysis

In article number 2316150, Yong-Tae Kim and co-workers introduce a catalytic approach for enhancing the RC by decorating lead on Ni catalysts. Decorating Ni catalyst with lead (Pb/Ni) catalyst exhibits improved HER activity as well as remarkable RC-flow resistance. The decoration of the Ni catalyst with Pb offers high-RCSFη (6.35) and -RCAFη (14.11 mA cm⁻²) under repetitive shutdown conditions, which are 5 times higher than those of bare Ni. Moreover, they validate the operational durability of Pb/Ni against RC flow phenomena using an actual AWE stack.

The lifespan of lithium (Li) metal batteries (LMBs) can be greatly improved by the formation of inorganic‐rich electrode‐electrolyte interphases (EEIs) (including solid‐electrolyte interphase on anode and cathode‐electrolyte interphase on cathode). In this work, a localized high‐concentration electrolyte containing lithium bis(fluorosulfonyl)imide (LiFSI) salt, 1,2‐dimethoxyethane (DME) solvent and 1,2‐bis(1,1,2,2‐tetrafluoroethoxy)ethane (BTFEE) diluent is optimized. BTFEE is a fluorinated ether with weakly‐solvating ability for LiFSI so it also acts as a co‐solvent in this electrolyte. It can facilitate anion decomposition at electrode surfaces and promote the formation of more inorganic‐rich EEI layers. With an optimized molar ratio of LiFSI:DME:BTFEE = 1:1.15:3, LMBs with a high loading (4 mAh cm−2) lithium nickel manganese cobalt oxide (LiNi0.8 Mn0.1 Co0.1) cathode can retain 80% capacity in 470 cycles when cycled in a voltage range of 2.8–4.4 V. The fundamental understanding on the functionality of BTFEE revealed in this work provides new perspectives on the design of practical high‐energy density battery systems.

通过形成富含无机物的电极-电解质相（EEIs）（包括阳极上的固体-电解质相和阴极上的阴极-电解质相），可以大大提高锂（Li）金属电池（LMB）的寿命。这项研究优化了一种局部高浓度电解质，其中包含双（氟磺酰）亚胺锂盐、1,2-二甲氧基乙烷（DME）溶剂和 1,2-双（1,1,2,2-四氟乙氧基）乙烷（BTFEE）稀释剂。BTFEE 是一种氟化醚，对 LiFSI 具有弱溶解能力，因此也可作为该电解质的助溶剂。它可以促进阴离子在电极表面的分解，并促进形成更多富含无机物的 EEI 层。通过优化 LiFSI:DME:BTFEE = 1:1.15:3 的摩尔比，采用高负载（4 mAh cm-2）锂镍锰钴氧化物（LiNi0.8 Mn0.1 Co0.1）阴极的 LMB 在 2.8-4.4 V 的电压范围内循环 470 次后仍能保持 80% 的容量。这项研究揭示了对 BTFEE 功能的基本认识，为设计实用的高能量密度电池系统提供了新的视角。

In this paper, the effect of p–n heterostructures on the electro‐optical and heat regulation performances of polymer dispersed liquid crystal (PDLC) dimming films are studied. In detail, the WO3, Ag2O, and WO3/Ag2O p–n heterostructures are successfully synthesized via the co‐precipitation method. The products are analyzed by XRD, SEM, TEM, and XPS and the results demonstrated that the WO3 nanorods successfully grew on the surface of Ag2O. Compared to the primitive sample, the incorporation of p–n heterostructures into the composite films significantly enhances the electro‐optical properties. For a 20µm‐thick film, the saturation voltage (Vsat) decreases by 38.7% from 24.8 to 15.2 V, and the threshold voltage (Vth) is reduced by 22.9% from 12.7 to 9.8 V, while the contrast ratio reaches 132. Due to the molecular structure of the polymer monomers and the micro‐network structure of the film, the film exhibits high emissivity in the mid infrared spectrum, enabling enhanced dynamic cooling management through radiative cooling around the clock. Matrix & laboratory (MATLAB) calculations show that the maximum cooling power during the day and night reached 97.63 and 136.24W m‐2 K‐1, respectively. This research has great significance for the development of highly energy‐efficient smart windows.

As continuous wearable physiological monitoring systems become more ubiquitous in healthcare, there is an increasing need for power sources that can sustainably power wireless sensors and electronics for long durations. Wearable energy harvesting with thermoelectric generators (TEGs), in which body heat is converted to electrical energy, presents a promising way to prolong wireless operation and address battery life concerns. In this work, high performance TEGs are introduced that combine 3D printed elastomers with liquid metal epoxy polymer composites and thermoelectric semiconductors to achieve elastic compliance and mechanical compatibility with the body. The thermoelectric properties are characterized in both energy harvesting (Seebeck) and active heating/cooling (Peltier) modes, and examine the performance of wearable energy harvesting under various conditions such as sitting, walking, and running. When worn on a user's forearm while walking outside, the TEG arrays are able to power circuitry to collect photoplethysmography (PPG) waveform data with a photonic sensor and wirelessly transmit the data to an external PC using an on‐board Bluetooth Low Energy (BLE) radio. This represents a significant step forward on the path to sustainable body‐worn smart electronics.

Unprecedented Strength Enhancement Observed in Interpenetrating Phase Composites of Aperiodic Lattice Metamaterials 在非周期性晶格超材料的互穿相复合材料中观察到前所未有的强度增强效果

Simultaneous high strength and high toughness are highly sought‐after in lattice metamaterials, but these properties are typically mutually exclusive. To overcome this challenge, the development of interpenetrating phase composite (IPC), which incorporates a net matrix infill into the lattice, has shown great potential in overcoming these constraints and is thus of continuous practical interest. In this work, a novel aperiodic monotile truss lattice and polymer IPC that exhibit unprecedented enhancement in both strength and toughness are reported. Specifically, the aperiodic unit cell is inspired by Einstein's monotile, a single space‐filling shape where the cell orientation never repeats. The IPCs are achieved through 3D‐printed Ti‐6Al‐4V truss lattices and epoxy infiltration. The highest gain in compressive strength reveals an impressive 246.61% increase, significantly exceeding the “1 + 1 > 2” idealization typically associated with strength in IPC metamaterials. Furthermore, a high specific energy absorption of 46.2 J g−1 demonstrates superior toughness. The underlying mechanisms, including damage sequences, two‐phase interactions, and geometric effects between truss and epoxy, are fully elucidated. Overall, this work reports unprecedented enhancement in IPC's properties and demonstrates the potential of utilizing idealized structures to achieve an optimal combination of strength and toughness in mechanical metamaterials.
