An Updated Kinetic Mechanism for the Combustion Inhibition of 2-Bromo-3,3,3-trifluoropropene (2-BTP)

2-Bromo-3,3,3-trifluoropropene (2-BTP, CF3CBr=CH2) is a promising halogenated flame suppressant, but its effects on flame propagation depend strongly on the coupled bromine and hydrocarbon chemistry. In this study, an updated kinetic mechanism was developed to describe the effect...

Effect of Binders on the Dynamic Slag and Iron Erosion Behavior of Taphole Clay

Dynamic slag and hot metal erosion tests were performed by the rotating cylinder method to evaluate the erosion resistance of taphole clay with different binder systems under high‐temperature flowing media. Macroscopic diameter changes, XRD phase analysis, and SEM–EDS observation...

Coupling Analysis of Multiple Meteorological Elements and Atmospheric Electric Field in the Lower and Middle Atmosphere (Troposphere and Stratosphere)

Severe convective weather can generate strong electrostatic fields and electromagnetic radiation, significantly inducing electrification processes in the lower and middle atmosphere (0–45 km) and perturbing space charge distributions. The perturbations to the lower-atmospheric el...

A multi-attribute decoupled learning network for precise segmentation of complex defects on steel surface

In the steel manufacturing industry, precise segmentation of surface defects is critical for achieving high-quality product control. Steel surface defects encompass various types such as cracks, scratches, and weld slag, which exhibit significant disparities in size, shape, and t...

Function-Switchable Superconducting-Spintronic Devices for Read-Protected Data Storage

Abstract Superconductivity and charge-to-spin conversion are both desirable for low-dissipation information processing, but they usually operate in different material platforms. Here we show that the p-orbital alloy In2Bi combines type-II superconductivity below 5.6 K with effici...

A Self-Marangoni-Propelled Droplet Microarray for Ultrafast Mixing and Point-of-Care Assay of Acute Myocardial Infarction Biomarkers

Abstract Droplet microarrays hold great promise for acute myocardial infarction (AMI) diagnosis, yet their biosensing performance is often limited by poor mixing efficiency and nonuniform signal distribution. Here, we report a self-Marangoni-propelled droplet microarray featuring...

Solid–Liquid Equilibria of the K+,Al3+//SO42–-H2O and Rb+,Al3+//SO42–-H2O Systems at 298.15 and 323.15 K

Abstract Rubidium is currently extracted primarily from rubidium ores, and its low-grade and complex associated components lead to difficult separation and high production costs, hindering large-scale utilization. Alum salt precipitation is a low-cost and industrializable method...

A review on process routes and inter-process coupling mechanisms of metallic bipolar plates for fuel cells

Metallic bipolar plates are critical components of PEMFCs, and their manufacturing involves a strongly coupled process chain comprising substrate selection, coating, forming, and joining. This review systematically analyzes the coupling mechanisms among these processes and reveal...

Development and performance evaluation of a novel borehole protection screen pipe for preventing borehole collapse in soft and fragmented rock strata

High-level roof borehole is one of the core technologies for gas control in high-gas mines in China. However, in soft and fragmented rock strata, the influence of mining-induced stress disturbance often causes compression-torsion deformation, borehole wall collapse, or dislocatio...

Preliminary analysis of the materials and production of Shang Dynasty pottery from Zhengzhou Shang City

Zhengzhou City, the capital during the early Shang period, witnessed the Shang Dynasty’s early splendor. This study presents chemical and petrographic analyses of 154 pottery artifacts from the Erligang period, excavated in the Northern Area of Shuyuan Street. The findings reveal...

How does public data openness strengthen urban economic resilience? Evidence from Chinese cities

Public data openness (PDO) has become an important component of digital government, but its effect on urban economic resilience (UER) remains insufficiently understood. Using panel data for 279 Chinese prefecture-level cities from 2011 to 2022, this paper exploits the staggered l...
