Ultraviolet (UV)-induced degradation is one of yazhi design saree the major problems in the field of perovskite solar cells (PSCs).Therefore, exploring materials and techniques to prevent UV light from penetrating into the device is urgently necessary.Here, we developed a special transparent fluorinated polyimide (FPI) resin, which can be directly
Lignin is a major component of lignocellulosic biomass along with cellulose and hemicellulose, currently underutilized with the bulk of technical lignin being combusted for heat generation in plant.From the technoeconomic perspective, the success of a future biorefinery is highly dependent on lignin valorization.However, structural complexity, hete
This paper analyses the causes of an incident in an aircraft propeller hub.The aluminum alloy propeller blade hub was detached from the plane bearing one of its two blades with the other one being jettisoned away.Stereoscopic examination of the fractured hub festool fs-wa/90 revealed that it was initially cracked by fatigue, with the crack initiati
Dung beetles are secondary seed dispersers, incidentally moving many of the seeds defecated by mammals vertically (seed burial) and/or horizontally as they process and relocate dung.Although several studies have quantified this ecological function of dung beetles, very few have followed seed fate until seedling establishment, and most of these have
