Background As the world’s largest coal producer, China was accounted for about 46% of global production. Among present mining risks, methane gas (called in this paper) explosion or ignition an underground mine remains ever-present. Although many techniques have been used, accidents associated with complex elements gassy mines need more robust monitoring warning systems to identify risks. This paper aimed determine which single method between PCA and Entropy methods better establishes a...
Abstract Monitoring nitrogen utilization efficiency and soil temperature in agricultural systems for timely intervention is essential crop health with reduced environmental pollution. Herein, this work presents a high‐performance multi‐parameter sensor based on vanadium oxide (VO X )‐doped laser‐induced graphene (LIG) foam to completely decouple oxides (NO ) temperature.

Abstract Organometal halide perovskites have been considered as promising candidates for high‐performance low‐cost photodetectors. Nonetheless, perovskite photodetectors are usually built on glass or polymer substrates, their UV‐C (200–280 nm) photodetection ability is quite limited due to the high absorption of substrates. Here, a uniform UV photodetector array which integrates photodiodes with inorganic CsPbBr 3 quantum dot (QD) fluorophor reported. not only acts an efficient...
With the in-depth development of Internet Things (IoT) and constant discussion 6G visions, future indoor location-based services (LBSs) in 6G-enabled IoT is attracting people's attention. In fact, due to continuous updating network techniques, complexity environment number connected wireless access points (APs) will increase dramatically, which leads diversity received signal strength (RSS) on performance propagation distance estimation, resulting low positioning accuracy poor robustness....

Abstract A new type of spin-current filter is proposed that consists a single-molecule magnet (SMM) coupled to two normal metal electrodes. It shown this tunneling junction can generate highly spin-polarized current, whose spin polarization be switched by means magnetic fields and gate voltages applied the SMM. This switching in SMM tunnel arises from spin-selective single-electron resonant via lowest unoccupied molecular orbit The electron current spectrum still polarized absence an...
