AbstractSolar steam generation (SSG) presents a promising approach to addressing the global water crisis. Central to SSG is solar photothermal conversion that requires efficient light harvesting and management. Hierarchical structures with multi‐scale light management are therefore crucial for SSG. At the molecular and sub‐nanoscale levels, materials are fine‐tuned for broadband light absorption. Advancing to the nano‐ and microscale, structures are tailored to enhance light harvesting through internal reflections, scattering, and diverse confinement effects. At the macroscopic level, light capture is optimized through rationally designed device geometries, configurations, and arrangements of solar absorber materials. While the performance of SSG relies on various factors including heat transport, physicochemical interactions at the water/air and material/water interfaces, salt dynamics, etc., efficient light capture and utilization holds a predominant role because sunlight is the sole energy source. This review focuses on the critical, yet often underestimated, role of hierarchical light harvesting/management at different dimensional scales in SSG. By correlating light management with the structure‐property relationships, the recent advances in SSG are discussed, shedding light on the current challenges and possible future trends and opportunities in this domain.

AbstractSurgery remains an essential treatment for managing drug‐resistant focal epilepsy, but its accessibility and efficacy are limited in patients without distinct structural abnormalities on magnetic resonance imaging (MRI). Potassium ion (K+), a critical marker for seizure‐associated neuronal signaling, shows significant promise for designing sensors targeting hidden epileptic foci. However, existing sensors cannot cross the blood‐brain barrier and lack the ability to specifically enrich and amplify K+ signals in the brain with high temporal and spatial resolution. Here, an intravenously administered neuronal signal sorting and amplifying nanosensor (NSAN) is reported that combines real‐time dynamic reversible K+ fluorescence imaging with high‐resolution structural MRI, enabling electroencephalogram‐concordant imaging of MRI‐negative epileptic foci. Guided by NSANs, minimally invasive surgery is successfully performed in both intrahippocampal kainic acid (KA) epilepsy model with foci confined to the ipsilateral hippocampus, and intraperitoneal KA model where foci are randomly distributed, resulting in sustained seizure control and cognitive improvement. These findings highlight the NSAN as a transformative tool for visualizing hidden epileptic foci, thereby broadening eligibility for minimally invasive and precision surgical intervention.

AbstractAmmonia (NH3) is widely recognized as a crucial raw material for nitrogen‐based fertilizer production and eco‐friendly hydrogen‐rich fuels. Currently, the Haber–Bosch process still dominates the worldwide industrial NH3 production, which consumes substantial energy and contributes to enormous CO2 emission. As an alternative NH3 synthesis route, electrocatalytic reduction of NOx species (NO3−, NO2−, and NO) to NH3 has gained considerable attention due to its advantages such as flexibility, low power consumption, sustainability, and environmental friendliness. This review timely summarizes an updated and critical survey of mechanism, design, and application of Ru‐based electrocatalysts for NOx reduction. First, the reason why the Ru‐based catalysts are good choice for NOx reduction to NH3 is presented. Second, the reaction mechanism of NOx over Ru‐based materials is succinctly summarized. Third, several typical in situ characterization techniques, theoretical calculations, and kinetics analysis are examined. Subsequently, the construction of each classification of the Ru‐based electrocatalysts according to the size of particles and compositions is critically reviewed. Apart from these, examples are given on the applications in the production of valuable chemicals and Zn−NOx batteries. Finally, this review concludes with a summary highlighting the main practical challenges relevant to selectivity and efficiency in the broad range of NOx concentrations and the high currents, as well as the critical perspectives on the fronter of this exciting research area.

AbstractPolymer dielectrics are crucial for electronic communications and industrial applications due to their high breakdown field strength (Eb), fast charge/discharge speed, and temperature stability. The upcoming electronic‐electrical systems pose a significant challenge, necessitating polymeric dielectrics to exhibit exceptional thermal stability and energy storage capabilities at high temperatures. Here, ultra‐high dielectric constant (ɛr) and charge/discharge efficiency (η) of 0.55Bi0.5(Na0.84K0.16)0.5TiO3‐0.45(Bi0.1Sr0.85)TiO3 (BNKT‐BST) ceramics are prepared by the solid‐phase reaction method and added to polyetherimide (PEI) to form BNKT‐BST/PEI nanocomposites with various structures. The findings indicate that the sandwich‐structured BNKT‐BST/PEI nanocomposite achieves the highest discharged energy density (Ud) of 7.7 J cm−3 with η of 80.2% when the Eb is 650 MV m−1 at 150 °C. This is primarily due to the incorporation of BNKT‐BST nanoparticles and the multilayer structure design, which significantly improves the composite's ɛr and Eb. Additionally, the sandwich‐structured composites show excellent cycling stability at 500 MV m−1 and 150 °C, with Ud of ≈ 4.7 J cm−3 and η greater than 90%. The research presents nanocomposites with high energy storage density and excellent stability, crucial for the practical application of polymer dielectrics in high‐temperature environments.

Published: December 2024

AbstractSurface‐enhanced Raman spectroscopy (SERS) technology boasts merits of fingerprint recognition, a low detection limit, high sensitivity, and straightforward operation, and holds a significant position in the realm of molecular detection (even at the single‐molecule level). Recently, molybdenum disulfide (MoS2), as a special SERS substrate, has demonstrated various advantages like high molecular compatibility and an anti‐fluorescence background, thus emerging as a promising non‐metal substrate. Nevertheless, so far, how to improve and achieve SERS effects comparable to metal substrates remains a challenge for MoS2 based substrates. Therefore, this work presents and acquires a 3D hollow structured MoS2, which can be achieved through a simple hydrothermal method. Fortunately, the substrate achieves a detection limit of 10−8 M and an enhancement factor of 106 for rhodamine 6G (R6G) molecules, significantly improving the performance of the non‐noble‐metal MoS2 SERS. Theoretical analysis suggests that this should be attributed to the enhanced charge transfer between the substrate and probe molecules brought by the distinct monolayer self‐assembly and oxygen substitution in the 3D MoS2 architecture. The work provides a novel method to enhance the SERS performance of 2D materials, which is readily achievable and is expected to become a key cornerstone for the development of composite substrates.

Authors: Zhu Jun , Wu Zhongbo 
Published: December 2024

AbstractColor filters are extensively utilized in various applications, including photovoltaic devices, printing, liquid crystal displays, image sensors, digital photography, projection systems, and other optical instruments. In this paper, an F‐P cavity structure based on an metal‐insulator‐metal (Ag‐ZnS‐Ag) structure is designed. By selecting specific materials and tuning structural parameters, strong coupling effects are formed through the interaction between the Fabry‐Pérot (FP) resonance in the intermediate dielectric cavity and the LSP resonance on the metal surface. This structure can generate a narrow‐band resonance peak within the visible light spectrum. By tuning the thickness of the dielectric cavity, color filtration across the 380–700 nm range can be dynamically obtained, enabling continuous multi‐band filtering within visible light. Within the visible light range, this structure, functioning as a filter, can achieve a transmission efficiency of up to 56% and a FWHM of 10–24 nm. Additionally, this structure can be used to design wide‐color gamut plasma filters for constructing RGB color spaces. When the ZnS thickness is 55 nm, it corresponds to the blue channel of the color space; at 75 nm, it corresponds to the green channel; and at 95 nm, it corresponds to the red channel. This color space can cover 100% of the sRGB color gamut and 99.946% of the Adobe RGB color gamut. In summary, this structure provides a new approach for designing simple, photolithography‐free plasma filters that enable multi‐band color filtration and exhibit a wide color gamut.

AbstractCr3+‐doped near‐infrared (NIR) phosphors have attracted significant attention in recent years. Despite this, achieving high‐performance NIR phosphors with broadband emission and excellent thermal stability remains a considerable challenge. This study presents Lu3Ga5O12:Cr3+, which demonstrates a tunable emission peak ranging from 705 to 759 nm and an increased full‐width at half‐peak maximum (FWHM) from 46 to 139 nm by substituting the [Mg2+‐Ge4+] chemical unit for the [Ga3+‐Ga3+] unit. Additionally, in Lu3MgGa3GeO12:Cr3+, Yb3+, an energy transfer channel (Cr3+‐Yb3+) is constructed. Under blue light excitation, the characteristic emission peaks of Cr3+ (600–900 nm) and Yb3+ (900–1100 nm) are observed simultaneously. However, the emission band between 850 and 900 nm is relatively weak, resulting in a discontinuous emission spectrum. To address this, Lu3MgGa3GeO12:Cr3+, Yb3+, Nd3+ phosphors are proposed, which exhibit a continuous broadband NIR emission with a FWHM of 253 nm and internal quantum efficiency of 47.3%. The luminescence intensity retains 81% of its room temperature value even at 423 K. Combining this new phosphor with a blue LED chip results in a portable NIR light source with potential applications in non‐destructive detection, information encryption, bio‐imaging, and NIR remote control. This work offers a novel perspective for developing high‐performance NIR phosphors.

Published: December 2024

AbstractThiahelicenes, an important subclass of helicenes, are renowned for their pronounced chiroptical properties, particularly circular dichroism. However, the exploration of their circularly polarized luminescence (CPL) has been hindered due to their inherently weak fluorescence, leaving a critical gap in the development of thiahelicenes as efficient CPL emitters. To address this limitation, a novel strategy for enhancing the luminescence of thiahelicenes by integrating thiophene‐containing units with a highly emissive hexabenzoperylene (HBP) core is presented. Two isomeric HBP‐cored double thiahelicenes are synthesized, which serve as proof of concept. These molecules exhibit exceptionally high fluorescence quantum yields (ΦF = 83% and 91%), surpassing all previously reported thiahelicenes. Furthermore, their luminescence dissymmetry factors show a four‐fold enhancement compared to the parent HBP, resulting in a remarkable CPL brightness of up to 84.9 M−1 cm−1. These findings not only address the fluorescence limitation of thiahelicenes but also establish a new pathway for developing high‐performance CPL materials.

Published: December 2024

AbstractHigh‐efficiency multi‐resonance thermally activated delayed fluorescence (MR‐TADF) emitters with narrowband emission show great potential for organic light‐emitting diodes (OLEDs). However, their inherent planar rigid structures often lead to intractable challenges of spectral broadening, self‐quenching, and low device efficiency at high dopant concentrations. Herein, two steric isomers, BN‐1TPh and BN‐2TPh, are designed by incorporating bulky shielding unit (1,3,5‐triphenylbenzene) at the para‐position of the B atom in the MR skeleton to hinder intermolecular interactions. They both show enhanced photoluminescence quantum yields (PLQYs) as compared with the model compound BCzBN. The corresponding OLEDs based on BN‐1TPh and BN‐2TPh display the maximum external quantum efficiency (EQEmax) values of up to 30.8% and 30.4% with narrow full width at half maximum (FWHM) bands of 27 and 28 nm, respectively. It is worth noting that even at the high doping ratio of 20%, the EQEs are still maintained 24.8% and 25.7% with almost unchanged emission spectra. These results show that segregating the planar MR‐TADF skeleton with spatial shielding structure can weaken the intermolecular interaction, which is one of the effective ways to resist the aggregation‐caused quenching effect and achieve high‐efficiency concentration‐indispensible MR‐TADF OLEDs.

AbstractThe high photoelectric conversion efficiency (PCE) of solar cells and their environmentally friendly, low‐carbon manufacturing processes are crucial for advancing carbon neutrality goals. This study introduces Fresnel lenses to focus sunlight for the sintering of mesoporous titanium dioxide (m‐TiO2) layers as an innovative method for fabricating perovskite solar cells (PSCs), effectively circumventing the energy‐intensive and carbon‐emitting high‐temperature furnace sintering traditionally required. Through this concentrated solar annealing technique, an efficient and eco‐friendly sintering of the m‐TiO2 layer is successfully achieved by removing organic residues from the precursor film and enhancing the film's transmittance, electrical conductivity, and grain size. Consequently, this has led to improved coverage of the perovskite layer and enhanced overall photovoltaic performance of the solar cells. Experimental results indicate that the m‐TiO2 film subjected to 60 min of concentrated sunlight sintering (CSS) demonstrates optimal photovoltaic performance, with the fabricated compact‐layer‐free PSCs achieving an impressive photoelectric conversion efficiency of up to 17.69%. This research not only offers a novel, cost‐effective approach for the sustainable production of PSCs but also contributes tangible solutions for the green transformation of the photovoltaic industry and the achievement of carbon neutrality. This work points the way toward using solar energy to prepare solar power generation devices.

AbstractImmune checkpoint inhibitors have demonstrated remarkable efficacy across various cancer types. However, immune‐related adverse events (irAEs) pose a significant challenge in immunotherapy, particularly the associated pneumonia as the primary adverse reaction, which can lead to irreversible pulmonary fibrosis. Additionally, monotherapy with programmed death ligand (PD‐L1) inhibitors has shown limited effectiveness. Therefore, to improve the response rate of immunotherapy and reduce pulmonary fibrosis, this study designed and prepared an intelligent nanodrug based on dendritic mesoporous silica nanoparticles (DMSNs) loaded with a sono‐sensitive agent protoporphyrin IX (PpIX). Additionally, a reactive oxygen species (ROS) sensitive linker is used to attach the immunotherapeutic drug PD‐L1 inhibitor (aPD‐L1) to DMSNs via covalent bonds. The external ultrasound (US) activates PpIX to generate ROS, which breaks the linker to release aPD‐L1 to induce sonodynamic therapy (SDT) and immunotherapy. This sono‐immnotherapy approach demonstrated excellent outcomes in tumor inhibition, eliciting immune responses, and reducing pulmonary fibrosis. Overall, this study offers a new, efficient, and safe method for breast cancer treatment, and expands the application of immunotherapy.

AbstractAfter the publication of “Direct formation of hard‐magnetic tetrataenite in bulk alloy castings” Ivanov et al., Advanced Science 10 (2022) 2204315, the authors identified a potential misinterpretation of the experimental data. Further work confirms that the original conclusions cannot be supported, and accordingly the paper is retracted. X‐ray diffraction shows the presence of (Fe,Ni)3P, giving additional Bragg peaks that were previously attributed to tetrataenite. Extra Bragg reflections observed in transmission electron diffraction, and earlier considered to be superlattice reflections from tetrataenite, instead result from oxidation of the sample surface during preparation. Measurements of magnetic hysteresis show no regions of high coercivity of the kind expected when tetrataenite is present. It is concluded that as‐cast bulk samples of Fe‐Ni‐P‐(C) show no evidence of tetrataenite on any length scale. Nevertheless, the addition of phosphorus should remain of interest in ongoing efforts to manufacture tetrataenite.

AbstractBig data and artificial intelligence are driving increasing demand for high‐density data storage. Probe‐based data storage, such as mechanical storage using an atomic force microscope tip, is a potential solution with storage densities exceeding hard disks. However, the storage medium must be modifiable on the nanoscale. While polymers are promising storage media, they face challenges with synthesis, erasing temperatures, and stability. Here, a low‐cost and robust polymer system is reported that allows repeated writing, reading and erasing. The polymer is made by inverse vulcanization, providing a network of S─S bonds that can be broken and re‐formed repeatedly. This property is leveraged in mechanical indentation to encode information, and thermal S─S metathesis and polymer re‐flow to erase. Exquisite control of indentation depth is possible over 1–30 nm. This control enables data encoding not just as a function of the presence or absence of an indent, but also indentation depth. This ternary coding increases the data density four‐fold over binary coding. Furthermore, the coding can be done at room temperature which is rare for mechanical information storage. The low cost, ease of synthesis, and dynamic S─S bonds in these polymers are a promising advance in polymer storage media for probe‐based data storage.

AbstractDespite rapid advancements in anion exchange membrane water electrolysis (AEMWE) technology, achieving pure water‐fed AEMWE remains critical for system simplification and cost reduction. Under pure water‐fed conditions, electrochemical reactions occur solely at active sites connected to ionic networks. This study introduces an eco‐friendly patterning technique leveraging membrane swelling properties by applying mechanical stress during dehydration under fixed constraints. The method increases active sites by creating additional hydroxide ion pathways at the membrane‐electrode interface, eliminating the need for additional ionomers in the electrode. This innovation facilitates ion conduction via locally shortened pathways. Membrane electrode assemblies (MEAs) with patterned commercial membranes demonstrated significantly improved performance and durability compared to MEAs with conventional catalyst‐coated substrates and flat membranes under pure water‐fed conditions. The universal applicability of this technique was confirmed using in‐house fabricated anion exchange membranes, achieving exceptional current densities of 13.7 A cm−2 at 2.0 V in 1.0 M potassium hydroxide (KOH) and 2.8 A cm−2 at 2.0 V in pure water at 60 °C. Furthermore, the scalability of the technique was demonstrated through successful fabrication and operation of large‐area cells. These findings highlight the potential of this patterning method to advance AEMWE technology, enabling practical applications under pure water‐fed conditions.
