The quest for lightweight and functional materials poses stringent requirements on mechanical performance of porous materials. However, the contradiction between high strength elevated porosity severely limits their application scenarios in emerging fields. Herein, high-strength multifunctional mullite-based ceramic monoliths were fabricated utilizing waste fly ash hollow microspheres (FAHMs) by protein gelling technique. Owing to unique shell-pore structure inspired shell-protected...
A type of renewable energy, wind power, which has a large generating capacity, increasingly captured the world's attention. Forecasting speed is great significance in wind‐related engineering studies, planning and designing packs, farm management integration power into electricity grids. Because chaotic nature intrinsic complexity speed, reducing forecasting errors related to been an important research subject. This article proposes hybrid model based on wavelet neural network (WNN) method...
Based on the observation data of daily temperature and precipitation in summer autumn 68 representative meteorological stations Fujian Province from 1971 to 2018, using climate Tendency Rate, Mann-Kendall trend test, Morlet wavelet analysis other methods, this paper analyzes variation trends air annual periodic characteristics time series over a period approximately 48 years. The results show that years, showed an obvious upward trend, which had mutation around 2000, but was different,...
Intelligent and diversified development of modern detection technology greatly affects the battlefield survivability military targets, especially infrared, acoustic wave, radar expose targets by capturing their unavoidable infrared radiation, electromagnetic wave information, affecting survival penetration capabilities. Therefore, there is an urgent need to develop stealth-protective materials that can suppress reduce characteristics, weaken signals. Fibrous three-dimensional porous...
Abstract The objective of this paper is to propose a novel computational model for solving the problem accurately evaluating randomly induced road vibration response engineering vehicles traveling on rural roads. model, first, focuses unique pavement characteristics roads, constructs tire grounding function and innovatively introduces dynamic friction factor, successfully develops coupled stochastic excitation system interaction between loads 1/4 vehicle tires roads by applying power...
The carbon emissions of new energy vehicles (NEVs)have transited from the use stage to production stage, indicating that environmental impact NEVs in manufacturing cannot be ignored. To reduce and maintain profits, this study proposes a fuzzy multi-objective optimization model achieve sustainable planning scheme for NEVs. proposed not only considers maximum profits automobile enterprises but also minimum target process, coordinate optimal quantity. results show output different price ranges...
The Si3N4 foam ceramics with an outer shell (~500 ?m) have been prepared by utilizing reactive sintering and pre-embedded activated carbon powder. After at 1400 ?C for 6 h, the microstructure of exhibited staggered columnar crystals. And when nitridation temperature was increased to 1450 ?C, length crystal column in has increased, which resulted a higher aspect ratio. Moreover, time 10 transformed into equiaxed crystals, reduced ratio columns. However, inner porous region irregular...
Herein, the mixed α-Si3N4 nanowires with large diameter differences (35-400 nm) were prepared by repeated re-filling of nitrogen gas during high temperature nitridation, and length thereof was substantially above 500 μm (the longest even could reach centimeter level). And there significant in interplanar spacing growth direction different diameters. Moreover, oxidation resistance systematically analyzed obtained following results: reaction Si3N4 became intensified significantly at about 1100...
?-Si3N4 nanowires with diameters of 100-180 nm (Si3N4-W1) and 420-510 (Si3N4-W2) were synthesized by a modified chemical vapour deposition (CVD) method their microstructure changes after high-temperature oxidation studied. The results showed that both Si3N4 not significantly oxidized when the temperature was lower than 900?C. However, Si3N4-W1 began to change at 1200?C, while Si3N4-W2 remained almost unchanged. Moreover, Si3N4- W1 treatment 1400?C, weight gain 26.4% 13.7%, respectively.
Abstract Traditional structural safety criteria are difficult to apply in assessing the of refractory ceramics. Herein, a three-factor comprehensive criterion for assessment high-temperature ceramics is proposed based on failure mechanism For critical temperature difference criterion, changes sharply (530 °C) after boiler stop 120 s. Correspondingly, left crack length found be 21 μ m and finally propagates 10.87 cm (with density N = 1 −3 ) under thermal shock. strength attenuation cracks...
