The swift advancement of the Internet of Things (IoT) and the subsequent proliferation of smart devices have precipitated an exponential surge in demand for integrated analog-to-digital converters (ADCs) that exhibit low power consumption and high stability across a broad spectrum of applications. Despite the notable progress witnessed in conventional silicon-based ADCs, they continue to confront constraints pertaining to miniaturization, wearability, and power efficiency—critical parameters for the effective functionality of IoT devices. In recent years, two dimensional semiconductors (2DSCs) have attracted notable interest in low-power circuitry and flexible electronics due to their intrinsically atomic-scale thickness and exceptional electrical properties. However, integrating 2DSCs into analog circuits poses substantial challenges, especially in the context of complex mixed-signal circuits. The divergent design requirements for digital and analog circuits also complicate the achievement of high-performance ADCs on a single chip. This paper presents an innovative 3-bit Flash ADC circuit utilizing 2DSCs. Through the synergistic optimization of materials, fabrication processes, and circuit design, the nonlinearity of the ADC is significantly reduced, resulting in a differential nonlinearity (DNL) of 0.072 least significant bit (LSB), an integral nonlinearity (INL) of 0.128 LSB, and a remarkably low power consumption of only 3.36 μW.

物联网（IoT）的迅速发展和随后智能设备的激增促使对集成模数转换器（adc）的需求呈指数级增长，这些转换器在广泛的应用中表现出低功耗和高稳定性。尽管传统硅基adc取得了显著进展，但它们仍然面临着与小型化、可穿戴性和功率效率相关的限制，这些参数是物联网设备有效功能的关键参数。近年来，二维半导体（2dsc）由于其固有的原子尺度厚度和优异的电学性能，在低功耗电路和柔性电子领域引起了人们的极大兴趣。然而，将2dsc集成到模拟电路中面临着巨大的挑战，特别是在复杂的混合信号电路中。数字和模拟电路的不同设计要求也使单芯片上高性能adc的实现复杂化。本文提出了一种利用2dsc的新颖的3位Flash ADC电路。通过对材料、制造工艺和电路设计的协同优化，显著降低了ADC的非线性，差分非线性（DNL）为0.072最低有效位（LSB），积分非线性（INL）为0.128 LSB，功耗仅为3.36 μW。

Thermal superinsulation, arising from nanoporous aerogels with pore sizes < 70 nm, involves ultralow heat conduction with a thermal conductivity lower than that of stationary air (24 mW m⁻¹ K⁻¹). However, the inherently weak necklace connection mechanism between building units and the confined deformation space within nanopores result in the intrinsic brittleness of these materials. Additionally, improvements in their mechanical flexibility typically result in compromised thermal insulation performance. To address this limitation, we herein report a core–sheath structure design of La₂Y_0.4TiZr₂O_9.6 ceramic aerogel (CSCA) featuring a nanofibrous core framework for flexible deformation and a nanoporous aerogel sheath for thermal superinsulation. The resulting aerogel demonstrates remarkable mechanical flexibility with a compressive strain of up to 80% , a fracture strain of up to 21.9% and a bending strain of up to 100%, as well as thermal superinsulation with a conductivity of 21.96 mW m⁻¹ K⁻¹ at 26 °C and remains stable at working temperatures exceeding 1300 °C. Ultimately, proposed CSCA constitutes a fundamentally new approach in structure design to resolving the formidable mechanical–thermal tradeoff of aerogels, and it offers promising material configuration for further advancements in thermal superinsulation.

孔径小于70 nm的纳米多孔气凝胶具有超低热传导特性，其导热系数低于静止空气（24 mW·m-1·K-1）。然而，建筑单元之间固有的弱项链连接机制和纳米孔内有限的变形空间导致了这些材料的固有脆性。此外，其机械灵活性的提高通常会导致隔热性能的降低。为了解决这一限制，我们在此报道了La2Y0.4TiZr2O9.6陶瓷气凝胶（CSCA）的核心-鞘结构设计，该结构具有用于柔性变形的纳米纤维核心框架和用于超保温的纳米多孔气凝胶鞘。所制备的气凝胶具有优异的机械柔韧性，压缩应变高达80%，断裂应变高达21.9%，弯曲应变高达100%，并且在26℃时具有21.96 mW·m-1·K-1的超保温性能，并且在超过1300℃的工作温度下保持稳定。最终，提出的CSCA构成了一种全新的结构设计方法，以解决气凝胶的机械-热权衡问题，并为进一步发展超保温材料提供了有前途的材料配置。

Confinement capillarity based on functional coatings is an effective way to enhance water evaporation via generating thin water in the internal surfaces of porous photothermal materials. However, current functional coatings with confinement capillarity tend to be single-functional and easily detach from the substrates under mechanical compression, limiting their practical applications. Endowing evaporator with both durable confinement capillarity and versatility is still a great challenge due to the trade-offs among functional designs. Herein, inspired by nature, multifunctional cracked metal-phenolic networks (MC-MPNs) with durable confinement capillarity and photocatalysis are developed, which can be firmly decorated on porous sponges to fabricate high-performance and multifunctional evaporators. The crack patterns and surface microstructures of the MC-MPNs can be controlled, which not only generates an ultrathin water layer in the internal pores of a sponge to realize confinement capillarity, but also optimizes its photocatalysis properties. Therefore, the resultant evaporator can realize highly efficient evaporation (3.2 kg m⁻² h⁻¹) and dye photocatalysis without requiring H₂O₂ addition. Moreover, the cracks can act as a buffer zone to significantly enhance the stability of the MC-MPNs coatings under compression (negligible performance loss after 1000 cycles), breaking the bottleneck for the practical applications of confinement capillarity toward solar desalination and water remediation. This study will open an avenue to design multifunctional photothermal coatings with durable confinement capillarity, paving the way for their practical application in solar desalination and water remediation.

基于功能涂层的约束毛细作用是一种通过在多孔光热材料的内表面产生薄水来促进水分蒸发的有效方法。然而，目前具有约束毛细作用的功能涂层往往功能单一，在机械压缩下容易与基体分离，限制了其实际应用。由于功能设计之间的权衡，赋予蒸发器持久的约束毛细管和多功能性仍然是一个巨大的挑战。本文从自然界中获得灵感，开发了具有持久约束毛细和光催化作用的多功能裂纹金属-酚醛网络（mc - mpn），该网络可以牢固地装饰在多孔海绵上，用于制造高性能多功能蒸发器。mc - mpn的裂纹模式和表面微观结构可被控制，不仅在海绵内部孔隙中形成超薄水层，实现约束毛细作用，而且优化了其光催化性能。因此，合成蒸发器无需添加H2O2即可实现高效蒸发（3.2 kg m-2 h-1）和染料光催化。此外，裂缝可以作为缓冲带，显著提高MC-MPNs涂层在压缩下的稳定性（1000次循环后性能损失可以忽略不计），打破了约束毛细在太阳能脱盐和水修复中的实际应用瓶颈。该研究将为设计具有持久约束毛细管的多功能光热涂层开辟一条道路，为其在太阳能脱盐和水修复中的实际应用铺平道路。
