We highlight the emerging and rapidly developing area of dual-atom catalysts (DACs) for electrochemical CO2 reduction (ECR). The DAC concept should be ideal for the efficient catalysis of the ECR reaction, as DACs offer the same intrinsic advantages as single-atom catalysts, yet the additional atom also presents an additional degree of freedom for synergistic catalyst design. This is especially important for the effective catalysis of multi-step reactions such as the ECR reaction, hence the particular relevance of DACs for this reaction. Yet DACs still present many challenges that must be overcome. Here, we first report the unique advantages of the DAC concept for the ECR reaction. This serves as a basis for discussing potential design strategies for realizing effective ECR from DACs. Our review concludes with an exploration of the challenges in the field and how these might be addressed.

To realize magnonic devices, finding a way to make magnons better transport and efficiently pump their spin angular momentum across a ferromagnetic insulator (FMI)/normal metal (NM) interface is crucial. Here, we demonstrate that modulating magnon temperature in an FMI offers an effective way to manipulate magnon transport and can lead to significantly enhanced spin pumping when the process is driven by a temperature gradient. This modulation is achieved by engineering the interface between the substrate and the FMI in a substrate/FMI/NM heterostructure, such that the interface provides stronger energy exchange between phonons in the substrate and magnons in the FMI. We report a 265% enhanced spin Seebeck effect, which represents the thermally driven spin-pumping process, and a 122% enhanced magnon current density participating in the spin pumping. Theoretical and experimental evidence coherently indicate that the observed enhancement should be attributed to the modified magnon temperature profile in the FMI.

Layered hybrid perovskites (LHPs) have emerged as promising reduced-dimensional semiconductors for next-generation photonic and energy applications, wherein controlling the size, orientation, and distribution of quantum wells (QWs) is of paramount importance. Here, we reveal that bulky molecular spacers act as crystal-terminating ligands to form colloidal nanoplatelets (NPLs) during early stages of LHP formation. NPLs template the crystallization of LHPs. Using multi-modal diagnostics, we prove that NPLs ripen and grow, playing a decisive role in the time evolution of QW size, population distribution, and orientation. We demonstrate antisolvent drip interrupts NPL ripening and thereby controls QW orientation, population, and energy cascades within LHP films. Using this approach, we achieve low-threshold amplified emission (AE) with remarkable reproducibility. We further introduce synthesized NPLs in the antisolvent step of 3D perovskites to control facet orientation and achieve enhanced efficiency and stability in wide-bandgap solar-cell devices compared to untextured controls.

Water scarcity affects a significant portion of the global population, with two-thirds experiencing at least 1 month of water scarcity annually. To address this issue, research efforts have focused on developing renewable solar-driven desalination and atmospheric water harvesting (AWH) technologies. However, existing energy-free freshwater harvesting methods are limited by weather conditions and time constraints, hindering their widespread applications. In this critical review, we explore the potential application and research efforts aimed at achieving a full-day (24 h) water supply to enhance their commercial viability. We begin by discussing the material design for solar-driven 3D evaporators, highlighting their potential for water supply during both daytime and nighttime. Subsequently, we delve into promising materials and devices for developing full-day AWH technologies, including fog harvesting, dewing-condensation water harvesting, and adsorption-based water harvesting. Moreover, we examine hybrid water harvesting techniques that combine AWH with solar-driven desalination, highlighting promising material designs to fulfill dual functionality. Finally, we outline the remaining challenges and offer our insights to stimulate further breakthroughs in achieving a year-round full-day water supply. By advancing these technologies and overcoming existing limitations, we can make significant progress in alleviating water scarcity worldwide.

Fiber electronics-enabled smart textiles are highly desirable for applications such as biosensing, personal healthcare, and human-machine interactions. Previous works on fiber electronics have focused on optimizing the sensitivity/accuracy of electronic signals, whereas user-centric visual interfaces have not been extensively explored. Additionally, current optical sensing mechanisms face challenges in power supply, system integration, and scalable manufacturing. Here, we introduce a body-coupled visual sensing mechanism that utilizes ambient electromagnetic energy as a power source. This mechanism enables independent sensing of multiple nodes on a single fiber without the need for additional electronic components integrated into the fiber. Moreover, continuous manufacturing of this visual sensing fiber has been successfully achieved, ensuring compatibility with modern weaving techniques. We also demonstrate the applications of this visual fiber electronic device in touch sensing, humidity sensing, and solvent polarity detection. These findings provide a feasible strategy for future advancements in user-interactive visual fiber electronics.

Hot carriers generated by localized surface plasmon resonance (LSPR) in metal nanoparticles can drive chemical reactions such as secondary metal deposition and catalytic reactions. Rationally designing plasmonic nanostructures requires understanding how particle geometry impacts hot carrier reaction dynamics. Here we use liquid-phase transmission electron microscopy (LP-TEM) and an electron radiolysis-resistant solvent to visualize hot carrier-mediated silver deposition and gold nanorod (AuNR) reshaping. AuNRs grew primarily in the transverse direction and displayed tip sharpening and preferential growth at LSPR hotspots. Ex situ white-light illumination produced similar morphological and compositional changes, whereas radiolysis products did not. Growth dynamics relative to electron beam flux and AuNR orientation were consistent with numerical simulations of hot carrier generation. Isolating hot carrier-induced redox processes on AuNRs during LP-TEM enabled quantifying spatially varying hot electron reaction dynamics. This approach is expected to enable quantifying and visualizing a broad range of plasmonic carrier-mediated reactions.

Cancer-cell-secreted small extracellular vesicles, known as exosomes, represent a rapidly emerging family of cancer biomarkers. However, the current protocols for exosome analysis require complex equipment and lengthy procedures, which prevents their broad utilization for cancer diagnosis. We have engineered plasmonic gold nanoparticles combining molecular and nanoscale chirality, and have demonstrated that such nanoparticles in self-assembled films in a microfluidic device can isolate and analyze exosomes directly from blood plasma due to marker-specific chiroptical responses and volumetric electromagnetic resonance. Cancer exosomes can be distinguished from those from healthy donors by their giant polarization rotation signatures, and the observed dependence of plasmonic resonances on mutations of epidermal growth factor receptor suggests the possibility of in-line mutation/deletion analysis of protein cargo based on molecular chirality. The present microfluidic chips eliminate ultracentrifugation and improve the sensitivity and detection speed by at least 14 times and 10 times, respectively, enabling the rapid liquid biopsy of cancer.

Increasing extreme heat stress puts humans at risk of heat stroke and dehydration in outdoor environments. However, current personal thermal management (PTM) approaches in hot summers suffer from low cooling efficiency. Here, we designed a lightweight, hierarchically porous hydrogel (HPHG) with low density, robust breaking strength, high evaporation enthalpy, high solar reflectance, and infrared emissivity, and controlled evaporation speed. The HPHG shows strong and prolonged passive cooling: sub-ambient temperature cooling up to 22.5°C under direct sunlight and a prolonged cooling time of >15 h. The HPHG can also be fabricated into a lightweight cooling vest (<350 g), achieving an average temperature drop of 11°C compared to air temperature. The concept of HPHG proposed in this study opens an avenue for hydrogel as a lightweight and wearable material in PTM and solves the bottleneck problem of passive cooling under extreme heat stress in an outdoor environment.
