Room-temperature ammonia sensing via Nb2CTₓ/SnS2 nanocomposite sensor with enhanced selectivity

Authors: Waqas Saeed, Liaqat Rasheed, Ye Tian, Irshad Ahmad Mir, Baoji Miao, Shakeel Ahmed, Amina Zulfiqar, Xing Chen, Amna Manzoor

The detection of ammonia (NH3) is essential for environmental monitoring, industrial safety, and medical diagnosis. However, fluctuating environmental conditions and the limited stability of conventional sensing materials make it difficult to achieve highly selective, highly sensitive, and reliable NH3 sensing at room temperature. To improve NH3 selectivity, we investigated a dual-functionalized Nb2CTx/SnS2 composite containing both amine and carboxyl groups. Combining the superior NH3 adsorptio

Unraveling in-situ electrochemical reconstruction of indium oxide catalysts with oxygen vacancy for enhanced electrocatalytic CO2-to-formate conversion

Authors: Biao Hong, Wei Xiao

Indium-based materials have emerged as promising alternative catalysts for the selective electroreduction of CO2 to formate, yet the optimal catalytic configuration remains elusive. Herein, theoretical calculation reveals that metallic indium over oxygen vacancy-containing In2O3 support (In/In2O3-VO) possesses the lowest energy barriers (0.99 eV) for CO2 reduction to formate. A rational air-annealing strategy applied to In3+-adsorbed resin is developed to synthesize indium oxide catalysts contai

Enhancing the activation and cycling properties of V-based alloys by trace Ce doping

Authors: Haiyan Leng, Shangxuan Gao, Shuai Wang, Fenghang Jiang, Xinlong Shen, Siwei Chen, Xingbo Han, Qun Luo, Lei Yan, V. N. Kudiiarov

This study focused on improving the activation property and cycling stability of V78Ti6Cr16 alloy through trace Ce doping. V78Ti6Cr16Cex (x = 0, 0.2, 0.4) alloys were prepared by arc melting. The activation property, the kinetic and thermodynamic properties, the cycling stability and the cycling stability mechanism of the prepared alloys were investigated. The results show that trace Ce doping significantly improves the activation performance of the alloy. The kinetics changed little and the the

Impact toughness, crack initiation and propagation mechanism of Ti6422 alloy with multi-level lamellar microstructure

Authors: Jie Shen, Zhihao Zhang, Jianxin Xie

The influence of different solution and aging conditions on the microstructure, impact toughness, and crack initiation and propagation mechanisms of the novel α + β titanium alloy Ti6422 was systematically investigated. By adjusting the furnace cooling time after solution treatment and the aging temperature, Ti6422 alloy samples were developed with a multi-level lamellar microstructure, including microscale α colonies and αp lamellae, as well as nanoscale αs phases. Extending the furnace cooling

Achieving 2.6 GPa tensile strength with outstanding ductility in high-carbon low-alloy steel

Authors: Guoyang Li, Feilong Sun, Guilin Wu, Honghui Wu, Junheng Gao, Haitao Zhao, Yuhe Huang, Jun Lu, Chaolei Zhang, Shuize Wang, Xinping Mao

Increasing the carbon content in low-alloy steels is one of the most cost-effective and efficient methods for enhancing strength, often resulting in a significant reduction in ductility. In this study, a high-carbon low-alloy steel with a tensile strength of about 2.6 GPa and a total elongation of 12% was developed, through the synergistic applications of two key strategies: i) refine prior austenite grains (PAGs) leading to the transition of quenched microstructure from brittle twinned martensi

Pyrolytic/solvothermal synthesis of tubular g-C3N4@NiFe-layered double hydroxide for catalytic enhancement of hydrogen storage in LiAlH4

Authors: Riguang Cheng, Zhaoyu Liu, Hengxin Zhang, Pantrangi Manasa, Hongge Pan, Fen Xu, Lixian Sun, Federico Rosei, and Yan Wang

LiAlH4 is hindered for practical hydrogen storage by its high decomposition temperatures, slow kinetics, and poor reversibility. To address the kinetic issues, this study introduces a tubular g-C3N4-supported NiFe-layered double hydroxide (g-C3N4@NiFe-LDH) nanocomposite as a catalytic dopant for LiAlH4. The composite, synthesized via solvothermal and pyrolysis methods, features a well-defined tubular morphology (~3 μm in length, ~200 nm in diameter), which facilitates its homogeneous dispersion

Recovery of chalcopyrite from galena using ellagic acid as a lead-selective and environmentally friendly inhibitor: Experimental and mechanistic insights

Authors: Rong Peng, Liang Wang, Hao Lai, Jinpeng Cai, Peilun Shen, Dianwen Liu

This study explores the selective application of an environmentally friendly organic inhibitor, ellagic acid (EA), in the flotation separation of galena from chalcopyrite. Single-mineral flotation experiments revealed that the galena flotation recovery significantly decreased from approximately 95% to 6.16% following the addition of EA, whereas chalcopyrite maintained a high recovery of approximately 95%. In artificial mixed-ore flotation, effective separation was achieved under optimized condit

Enhanced visible light response and cytocompatibility of TiO2–TiC shell–core structured S-scheme photocatalyst

Authors: Yuanyuan Li, Sujun Guan, Yingda Qian, Liang Hao, Sheikh Mohamed Mohamed, Lijun Wang, Takaomi Itoi, Yun Lu, Xinwei Zhao

To enhance the visible light response of titanium dioxide (TiO2), titanium carbide (TiC) nanoparticles (NPs) were thermally treated in carbon powder, effectively overcoming the challenges associated with conventional doping methods. During the treatment, a TiO2 thin shell with oxygen vacancies (OVs) formed around the TiC NPs, creating a shell–core structure S-scheme photocatalyst. Transmission electron microscopy (TEM) and ultraviolet–visible (UV–vis) spectroscopy confirmed the successful format
