Abstract Phase change materials (PCMs) possess remarkable capability to store and release substantial amounts of energy during the processes melting crystallization across a wide temperature range, thus holding great promise in applications related regulation thermal storage. Herein, effectively address PCM leakage enhance conduction, microcapsules with melamine–formaldehyde resin (MF) shell were prepared using situ polymerization Pickering emulsions stabilized by cellulose nanofibrils...
In order to further optimize the microstructure and mechanical properties of TiB/TiAl composites, individual synergistic effects Ta Mn were investigated in this study. Ti43Al6Nb1.6B-xTa-yMn (x + y = 1, at%) termed as TNB, TNB-1Ta, TNB-1Mn TNB-0.5Ta0.5Mn, fabricated by vacuum arc melting. X-ray diffraction results showed that peak B2 phase appeared TNB-1Ta while it was not obvious TNB-0.5Ta0.5Mn counterpart, which indicated higher content formed with 1% or addition. According solidified...
The advancement of the digital economy is vital for decreasing agricultural carbon emissions and fostering high-quality development. Using panel data from 31 Chinese provinces between 2000 2021, this paper employs a dual machine learning model causal inference to analyze impact financial inclusion on intensity, its underlying mechanisms, characteristics heterogeneity. study finds that inclusive finance significantly reduces intensity through two main channels: enhancing scientific...
With the continuous development of deep learning, how to use computer vision technology accurately locate bolts and identify defects in complex natural backgrounds has become a common problem faced by both academia industry. Aiming at problems slow detection speed high false rate current bolt defect detection, an improved Faster R-CNN algorithm for transmission lines is proposed. First, with as basic framework, through experimental comparison three different backbone networks, ResNeSt higher...
