High sensitivity plays a crucial role in the development of wearable electronic devices. For fiber-based wearable sensors, the sensitivity mainly depends on the conductive properties and surface structure of the fibers. Researchers have made great progress in exploring novel structures and...

In this study desigs a new of orthogonal decagonal ring three-dimensional cutting force sensor. First, the viability of the sensor structure is established and the prototype is fabricated by theoretical analysis and simulation verification. Then the strain gauges are pasted to the orthogonal...

SnO 2 nanoparticles (NPs) have been widely employed as electron transport layers (ETLs) in planar n-i-p perovskite solar cells (PSCs). Perfect SnO 2 ETL/perovskite interface plays a key role in high efficiency PSCs, however, the main issues caused by the self-aggregation of the SnO 2 NPs and the...

China pledges to have its carbon emissions peak before 2030 and achieve carbon neutrality before 2060 (“Dual Carbon” targets). Beijing, the capital of China, needs to take the lead in promoting carbon emissions reduction so as to provide an example for other cities. Based on the extended...

Pupil segmentation is a first and important topic of iris recognition, identity recognition and eye movement information extraction for mental analysis. However, due to the negative effects of eyelash occlusion, eyelid occlusion and off-gaze deflection, making a precise pupil segmentation is a...

FeS2 was applied as an activator and reductant in nano calcium peroxide (nCP) based Fenton-like system to degrade naphthalene (NAP). The results indicated that 96.9% of NAP was removed within 180 min at optimal dosages in the nCP/FeS2 system and the NAP degradation efficiency was influenced by...

Aqueous energy storage systems based on ammonium-ion (NH4+) as charge carrier have attracted increasing interest owing to their great potential for large-scale application. Developing suitable cathodes (especially binder-free electrodes) for excellent NH4+ storage is still in their infancy....

It is crucial to design and synthesize a catalyst that can catalyze the production of cyclic carbonates from carbon dioxide and epoxide under mild conditions. Herein, we successfully synthesized a two-dimensional metal organic framework FeTPyP, which displays an outstanding capability to...
