在许多实际应用中,纺织品的疏水性和抗渗性非常重要。研究中,用六氟乙烷(C_2F_6)或六氟乙烷与氢气(H_2)或乙烯(C_2H_4)的混合物进行的等离子体表面氟化处理,被用来改善聚酯微纤织物的拒水性能。改变泵入气体的组分和处理工艺(即使用混合气体,还是两种气体依次使用)对材料表面进行的改性可通过测定材料表面接触角与滑动角以及用X-射线光电子谱(XPS)进行了分析。值得注意的是,用混合气体(C_2F_6加H_2或者C_2H_4)处理后,疏水性随着还原物质用量的增加而降低,而两步法(先用氢气或者乙烯气体处理后,再用C_2F_6处理)疏水性不随气体流速的改变而变化。通过测定一连串的水洗后的接触角和滑动角研究了被处理表面的稳定性。在等离子体C_2F_6中添加还原剂后,表面改性具有显著的水洗稳定性。

Gravity models given by higher-order scalar curvature corrections are believed to bear important consequences. Einstein-bel-Robinson (EbR) gravity with quartic curvature modification motivated Sajadi et al. to explore static spherically symmetric black hole solutions using perturbative methods. In this study, inspired by their work, we investigate AdS black hole shadows in EbR gravity and demonstrate how the gravity parameter alters the energy emission rate. Finally, we address the same problem in the presence of plasma, because the black holes are thought to be surrounded by a medium that changes the geodesic of photons.

With the increased interest of plants in space, gravity cannot be ignored when studying soil-plant-water relations. Therefore, it is important to understand the water relations of soils under zero gravity in space or under reduced gravity on the Moon or Mars. This paper outlines the problems of moving water in soils under zero gravity or microgravity, as well as growing plants in these soils. It is suggested that microgravity experiments could be done on Earth using both soils and plants. Results from such experiments could be used to grow plants when mankind establishes bases on the Moon and Mars.

In this work,we propose a stateless blockchain called CompactChain,which compacts the entire state of the UTXO(Unspent Transaction Output)based blockchain systems into two RSA *** first accumulator is called Transaction Output(TXO)commitment which represents the TXO *** second one is called Spent Transaction Output(STXO)commitment which represents the STXO *** this work,we discuss three algorithms:(i)To update the TXO and STXO commitments by the *** miner also provides the proofs for the correctness of the updated commitments;(ii)To prove the transaction’s validity by providing a membership witness in TXO commitment and non-membership witness against STXO commitment for a coin being spent by a user;(iii)To update the witness for the coin that is not yet spent;The experimental results evaluate the performance of the CompactChain in terms of time taken by a miner to update the commitments and time taken by a validator to verify the commitments and validate the *** compare the performance of CompactChain with the existing state-of-the-art works on stateless *** shows a reduction in commitments update complexity and transaction witness size which inturn reduces the mempool size and propagation latency without compromising the system throughput(Transactions per second(TPS)).
