1. März 2024 · The film's luminous modulation increased from −2.05 % to + 1.86 %, and its solar modulation increased to 8.35 % with luminous transmittance of 57.18 % at 30 °C, which was the best experimental result reported for a single layer film structure of the same thickness. Also, this study offered a new approach for improving the relationship between luminous transmittance and solar modulation ...
7. Dez. 2023 · Spin coating has been widely used to deposit functional thin films 2,7.To understand the role played by substrates on the texture, α-Fe 2 O 3 films were fabricated via spin coating with ...
Polylactide (PLA) composites with three types of fillers, calcium carbonate, barium sulfate, and mica, have been prepared. Methods of preparation were melt mixing in a Brabender plasticorder at ...
27. Juli 2020 · Well-controlled multilayer graphene up to four layers thick with a defined stacking sequence is synthesized via SiC alloy formation on a Cu(111) substrate.
PLA films and industrial hemp fiber-based biocomposites were then prepared by the film stacking process at varying fiber weight fractions (30, 35, and 40%). The PLA films and industrial hemp fiber mats were then alternately stacked in a mold (220 X 150 X 3.5 mm 3 ) and precompressed (2 MPa) at 185°C for 5 min using a compression molder.
1. Juni 2008 · Film stacking is used commercially for a variety of products where impregnation occurs in a double belt press [13], [14]. The FF process uses UD carbon fibres that have been spread under tension to give a highly aligned homogeneous un-impregnated (dry) fibre strip or ‘band’ that forms the full tape width, and hence the inter bundle effect is not applicable here, leading to a single scale ...
6. Okt. 2020 · In this research, we focus on China’s film market, the second-largest box office in the world. Our model is based on data regarding the nature of a film itself without word-of-mouth data from social platforms. Combining extreme gradient boosting, random forest, light gradient boosting machine, k-nearest neighbor algorithm, and stacking model ...
