Summary: In this study, a novel SnO2 nanorod/spindle-like Fe2O3 heterostructure was successfully fabricated through a simple two-step hydrothermal route, which showed improved gas sensing performance on volatile organic compounds compared to pure Fe2O3. The enhanced gas-sensitivity performance of the hierarchical SnO2/Fe2O3 heterostructures can be attributed to the synergistic effect and heterojunction of the interface between spindle-like Fe2O3 and SnO2 nanorod. This research may provide new insight and a rational strategy for upgrading the sensing performance of certain semiconductor metal oxide materials through the design of novel layered nanostructures in the future.

Summary: This study developed a noble metal decoration strategy to enhance the NO2 responses of alpha-Fe2O3/SnO2-rGO hybrids. The Pt modified alpha-Fe2O3/SnO2-rGO hybrids exhibited the highest response value attributed to their narrow band gap, small particle size, and excellent catalytic activity. The findings not only broaden the study of room-temperature gas sensors but also provide suggestions for discovering the gas sensing mechanism.

Summary: The alpha-Fe2O3/MoSe2 composite fabricated via a simple hydrothermal route shows high response to H2S gas sensing, with a faster response/recovery rate, outstanding repeatability, and anti-humidity interference at room temperature, as well as excellent selectivity for H2S compared to other potentially interfering gases. This improved performance is attributed to the increased active sites and specific surface area, as well as the formation of n-n heterojunctions at the interface between alpha-Fe2O3 hollow nanospheres and MoSe2 nanoflowers.

Summary: Alkali metals (Li, Na, and K) show promise as high-performance rechargeable alkali metal battery anodes due to their high theoretical specific capacity and low electrochemical potential. However, challenges such as high chemical reactivity, uncontrolled dendrite growth, unstable solid electrolyte interphase, and volume expansion during cycling processes hinder their practical application. The introduction of carbon nanotube-based nanomaterials in alkali metal anodes provides a solution to these issues. These nanomaterials with high specific surface area, superior electronic conductivity, and excellent mechanical stability have attracted considerable attention. This review summarizes recent progress on the application of carbon nanotube-based nanomaterials in stable and dendrite-free alkali metal anodes, discusses the merits and issues of alkali metal anodes, as well as their stabilizing strategies, and explores the relationship between synthesis methods, nano- or microstructures, and electrochemical properties of carbon nanotube-based alkali metal anodes. Additionally, advanced characterization technologies on the reaction mechanism of carbon nanotube-based nanomaterials in alkali metal anodes are reviewed. Finally, the challenges and prospects for future study and applications of carbon nanotube-based AMAs in high-performance alkali metal batteries are discussed.

Summary: Formaldehyde exposure during pregnancy can cause fetal congenital heart disease (CHD). High-throughput sequencing was used to identify the expression profiles of long non-coding RNAs (lncRNAs) in heart tissues of normal and formaldehyde-exposed newborn rats. A total of 763 differentially expressed lncRNAs were identified, and the Ras and hedgehog signaling pathways were identified as important regulatory pathways in CHD caused by formaldehyde exposure. Several upregulated lncRNAs were validated and may provide a reference for diagnosing and treating CHD.

Summary: Researchers developed coral-like carbon nanowires doped with nitrogen as a binder-free anode material for potassium-based dual-ion batteries. The unique porous nanostructure and amorphous/short-range-ordered composite feature of the carbon nanowires enhance structural stability, facilitate ion transfer, and improve active site utilization. The anode exhibits diffusive behavior and capacitive adsorption, delivering a high capacity of 276 mAh g-1 at 50 mA g-1, good rate capability up to 2 A g-1, and long-term cycling stability with 93% capacity retention after 2000 cycles at 1 A g-1. Assembling this anode with an environmentally benign cathode yields a potassium-based dual-ion battery with high specific capacity, excellent rate capability, and long-term cycling stability.

Summary: Researchers developed a one-pot solvothermal method to construct an amorphous/crystalline MoO2 (a/c-MoO2) homojunction for high-efficiency sodium-ion batteries. Theoretical simulations showed that electrons redistributing at the homogeneous interface of a/c-MoO2 facilitated charge carrier adsorption and electron/ion transfer. The a/c-MoO2 homojunction exhibited superior Na adsorbability (-1.61 eV) and low Na diffusion energy barrier (0.519 eV), leading to higher capacity, rate capability, and cycling stability compared to a-MoO2 or c-MoO2. Mechanistic studies using in-situ XRD and ex-situ XPS techniques revealed the 'adsorption-insertion-conversion' mechanism for Na' storage of MoO2. This work provides new opportunities for optimizing electrode materials through crystallographic engineering and enhances understanding of the effects of homojunction structure on electrochemical performance.
