Multifunctional tissue scaffold material nanodiamond (ND)/chitosan (CS) composites with different diamond concentrations from 1 wt % to 5 were synthesized through a solution casting method. The microstructure and mechanical properties of the characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), nanoindentation. Compared pristine CS, addition ND resulted in significant improvement properties, including 239%, 276%,...
Infrared imaging can overcome visual limitations in low-light and complex environments, but the presence of mixed noise significantly affects its practical performance. Existing denoising methods struggle to handle infrared images, while traditional visible light techniques cannot be directly applied due differences types principles. To address this, we propose a Transformer-based method that leverages ability learn long-range dependencies, effectively removing various noise. Experimental...
There is a pressing need to develop efficient and sustainable approaches harvesting microalgae for biofuel production water treatment. CO2-switchable crystalline nanocellulose (CNC) modified with 1-(3-aminopropyl)imidazole (APIm) proposed as reversible coagulant microalgae. Compared native CNC, the positively charged APIm-modified which dispersed well in carbonated water, showed appreciable electrostatic interaction negatively Chlorella vulgaris upon CO2-treatment. The gelation between...
An acidic mixture of sulfuric and fluosilicic acid (H2SO4+H2SiF6) was employed as lixiviant to enhance leaching lithium from lepidolite. The H2SiF6 obtained a byproduct anhydrous hydrofluoric production, aiming provide HF molecules. It found that the molecules were main reaction component played key role in strengthening dissolution Different factors, including mass ratio ore/H2SO4/H2SiF6, concentrations H2SO4 H2SiF6, temperatures (40−80 °C) time (15−75 min), investigated. Moreover, an...
Abstract The solid-state transformer (SST) in the renewable energy grid is developing way of high voltage and frequency, which often results a sharp increase heat production equipment accelerates failure insulating materials. Epoxy resin (EPR) commonly used as an insulation material for SST due to its excellent electrical properties, processing performance (viscosity), low price. However, thermal conductivity EPR only about 0.2 W/(m·K), leads poor under frequency temperature. To enhance...
Abstract Increasing forest soil organic carbon (SOC) storage is important for reducing dioxide (CO 2 ) emissions from terrestrial ecosystems and mitigating global climate change. Although the effects of altitude, temperature rainfall on have been studied extensively, it difficult to increase SOC by changing these factors in actual management. This study determined SOC, physical chemical properties, nutrient elements, heavy metal minerals microbial biomass 0–140‐cm layer monsoon broad‐leaved...
Uniform hematite polyhedra enclosed by high-activity facets could be selectively synthesized acetates-induced synthetic strategy.
The in-plane electrical and thermal conductivities of several polycrystalline platinum gold nanofilms with different thicknesses are measured in a temperature range between the boiling point liquid nitrogen (77 K) room by using direct current heating method. result shows that both reduce greatly compared their corresponding bulk values. However, conductivity drop is considerably greater than drop, which indicates influence internal grain boundary on heat transport from charge transport,...
Coal seam water injection is an important technical method to prevent and control coal gas outburst other disasters. Water can soften change its mechanical properties. In order study the properties of samples with different moisture content, briquette five moistures content (4%, 6%, 8%, 10%, 12%) were selected carry out triaxial compression tests under confining pressures (0.1, 0.2, 0.4, 0.8, 1.2 MPa). Then, response mechanism water-bearing was analyzed. The results show that slope linear...
In this study, a series of nano-Al2O3 reinforced polyimide (PI) composites were fabricated using the hot compression method. A silane coupling agent was used to modify surface powder enhance PI/Al2O3 interface compatibility. The effects Al2O3 contents on microstructures, thermal behavior and mechanical properties investigated. results suggested that chemical reactions occurred during in situ modification. cross-linked PI matrix, which reduced mobility chains improved elastic modulus...
