Carbon nanotubes (CNTs) are ideal candidates for constructing transparent conductive networks due to their excellent flexibility, desirable optical properties, and outstanding electrical characteristics. However, their performance is severely degraded by the junction resistance between individual CNTs. Herein, we prepared nearly invisible and transferable ultralong CNT conductive networks with high transmittance (>99% at 550 nm). The centimeter-scale length of ultralong CNTs facilitated the successful assembly of conductive and suspended networks with a minimal thickness, absorption area, and junction density, enabling ultrahigh transmittance and transferability. Further, we developed an ultralong CNT-based flexible and transparent pressure sensor to verify their practical value. The sensor exhibited a high sensitivity (225.11 kPa–1), a broad operating range (up to 160 kPa), a rapid response time (11 ms), and robust stability over 10,000 cycles, outperforming most state-of-the-art transparent pressure sensors.

Due to the inevitable dendrite and corrosion in metallic Zn anodes, alternative anodes of intercalation-type materials are desirable, but they still suffer from low energy efficiency, unsatisfactory capacity, and insufficient cycle life. Here, we develop a high-performance anode for aqueous Zn-ion batteries via a lattice expansion strategy in combination with a Zn2+/H+ synergistic mechanism. The anatase TiO2 with expanded lattice exhibits an appropriate deintercalation potential of 0.18 V vs Zn/Zn2+ and a high reversible capacity (227 mAh g-1 at 2.04 A g-1) with an outstanding rate capability and excellent cycle stability. The high electrochemical performance is attributed to a decrease in the Zn2+/H+ diffusion barriers, which results from lattice expansion and also a H+-promoted Zn2+ intercalation effect. The anode intercalates Zn2+/H+ via a solid-solution mechanism with a minor volume change, which contributes to the high reversibility and thus high energy efficiency. When paired with different types of cathodes, including NV, I2, and activated carbon, to construct corresponding full cells, high specific energy, high specific power, long cycle life, and extremely high energy efficiency can be achieved. This study provides a prospect for developing high-performance Zn-ion batteries.","PeriodicalId":21,"journal":{"name":"ACS Nano","volume":" ","pages":""},"PeriodicalIF":15.8,"publicationDate":"2024-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142666394","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two-dimensional (2D) MXenes possess adjustable structures and interlayer spacing, which provide an ideal platform for in-depth investigation of ion transport in 2D confined space; however, the strong interaction of the negatively charged terminations in MXenes hinders the transport of intercalated cations. In this work, we proposed a strategy that precisely regulates the surface modification of Ti3C2Tx MXene with the weak polarity of boron atoms (SCB-MXene) via the distinct effect of supercritical CO2. This not only could effectively substitute -OH termination in MXene but also can prevent the loss of -O active sites, and then, both ultrafast ion transport and high volumetric capacitance can be achieved simultaneously. Ideally, a volumetric capacitance up to 742.7 C cm-3 at 1000 mV s-1 for the SCB-MXene film as pseudocapacitive materials that provides an energy density of 66.3 Wh L-1 even at an ultrahigh power density of 132.5 kW L-1 is obtained, which is a prominent record of energy density and power density reported up to now. Subsequently, it can be used in large-scale energy storage and conversion devices.","PeriodicalId":21,"journal":{"name":"ACS Nano","volume":" ","pages":""},"PeriodicalIF":15.8,"publicationDate":"2024-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142646025","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A combined experimental and theoretical exploration of optical matter is essential to advance our understanding of the phenomenon and potentially design applications. Most studies have focused on nanoparticles composed of a single material (either metallic or dielectric), representing two extreme regimes, one where the gradient force (dielectric) and one where the scattering force (metallic) dominates. To understand their role, it is important to investigate hybrid materials with different metallic-to-dielectric ratios. Here, we combine numerical calculations and experiments on hybrid metal-dielectric core-shell particles (200 nm gold spheres coated with silica shells with thicknesses ranging from 0 to 100 nm). We reveal how silica shell thickness critically influences the essential properties of optical binding, such as interparticle distance, reducing it below the anticipated optical binding length. Notably, for silica shells thicker than 50 nm, we observed a transition from a linear arrangement perpendicular to polarization to a hexagonal arrangement accompanied by a circular motion. Further, the dynamic swarming assembly changes from the conventional dumbbell-shaped to lobe-like morphologies. These phenomena, confirmed by both experimental observations and dynamic numerical calculations, demonstrate the complex dynamics of optical matter and underscore the potential for tuning its properties for applications.","PeriodicalId":21,"journal":{"name":"ACS Nano","volume":" ","pages":""},"PeriodicalIF":15.8,"publicationDate":"2024-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142646028","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most existing distillation membranes exhibit three-dimensional (3D) stacking bulk structures, where the zigzag water-repellent channels often lead to limited permeability and high energy costs.

By tailoring the phase separation rate, the polymer phase evolved into continuous hydrophilic webs in situ weld on the microporous hydrophobic layer. The webs possess true-nanoscale architectures (internal fiber diameter of ∼20 nm, pore size of ∼140 nm) with enhanced roughness, serving as a superspreading surface to reach a water contact angle of 0° in 1.7 s. Benefiting from the architecture and wettability dual asymmetries, the obtained Janus membrane shows high-efficiency desalination performance (salt rejection >99%, flux of 11 kg m-2 h-1, and energy efficiency of 79%) with a thickness of 6.7 μm.

However, due to water isolation, achieving a hydrochromic effect in perovskite-polymer composite remains elusive, notwithstanding its importance as a potentially commercial-ready material. Here, we demonstrate a hydrochromic effect of perovskite-polymer-based porous composite via a nonsolvent-induced phase separation method, comprising of FA2PbBr4/poly(vinylidene fluoride) (FA = formamidinium). The naturally formed pores serve as microchannels, facilitating moisture diffusion. The penetrated water induces a phase transition of perovskite material from the nonfluorescent two-dimensional FA2PbBr4 to the fluorescent three-dimensional FAPbBr3.

Chemical vapor deposition (CVD) is a widely used technique for preparing large-area and high-quality TMDCs. Yet, it suffers from the challenge of transfer due to the strong interaction between 2D materials and substrates. The traditional PMMA-assisted wet etching method tends to induce damage, wrinkles, and inevitable polymer residues. In this work, we propose an etch-free and clean transfer method via a water intercalation strategy for TMDCs, ensuring a high-fidelity, wrinkle-free, and crack-free transfer with negligible residues. Furthermore, metal electrodes can also be transferred via this method and back-gate field-effect transistors (FETs) based on CVD-grown monolayer WSe2 with van der Waals (vdW) metal/semiconductor contacts are fabricated. Compared to the PMMA-assisted transfer method (∼1.2 cm2 V-1 s-1 hole mobility with ∼2 × 106 ON/OFF ratio), our high-fidelity transfer method significantly enhances the electrical performance of WSe2 FET over one order of magnitude, achieving a hole mobility of ∼43 cm2 V-1 s-1 and a high ON/OFF ratio of ∼5 × 107 in air at room temperature.","PeriodicalId":21,"journal":{"name":"ACS Nano","volume":" ","pages":""},"PeriodicalIF":15.8,"publicationDate":"2024-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142646013","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While advanced water production plants are prevalent in urban areas, remote islands and sparsely populated regions face significant obstacles in establishing such technologies. Consequently, there is an urgent need for efficient, affordable, and sustainable water production technologies in these areas. Herein, we present a facile approach utilizing an ultrashort-pulsed laser to directly convert cotton fabric into graphene under ambient conditions. The resulting laser-induced graphene (LIG) demonstrates the highest light absorption efficiency of 99.0% and a broad absorption range (250-2500 nm). As an excellent solar absorber, LIG on cotton fabric can efficiently absorb 98.6% of the total solar irradiance and its surface temperature can reach 84.5 °C under sunlight without optical concentration. Moreover, we propose a cost-effective 3D LIG evaporator (LIGE) for continuous solar-powered desalination. This innovative design effectively mitigates salt formation issues and enhances the steam generation efficiency. The water evaporation rate and the solar-to-vapor conversion efficiency are measured to be around 1.709 kg m-2 h-1 and 95.1%, respectively, which surpass those reported in previous studies.
