Here, we report the construction of magnetic core-shell microparticles for oil removal with thermal driving regeneration property. Water-in-oil-in water (W/O/W) emulsions from microfluidics are used as templates to prepare core-shell microparticles with magnetic holed poly (ethoxylated trimethylolpropane triacrylate) (PETPTA) shells each containing a thermal-sensitive poly (N-Isopropylacrylamide) (PNIPAM) core. The microparticles could adsorb oil from water due to the special structure and be collected with a magnetic field. Then, the oil-filled microparticles would be regenerated by thermal stimulus, in which the inner PNIPAM microgels work as thermal-sensitive pistons to force out the adsorbed oil. At the same time, the adsorbed oil would be recycled by distillation. Furthermore, the adsorption capacity of the microparticles for oil keeps very stable after 1st cycle. The adsorption and regeneration performances of the microparticles are greatly affected by the size of the holes on the outer PETPTA shells, which could be precisely controlled by regulating the interfacial forces in W/O/W emulsion templates. The optimized core-shell microparticles show excellent oil adsorption and thermal driving regeneration performances nearly without secondary pollution, and would be a reliable green adsorption material for kinds of oil.

Emerging applications such as smart city infrastructures and virtual reality landscapes are setting rigorous benchmarks for 6G mobile networks, requiring elevated levels of confidentiality, integrity, nonrepudiation, authentication, and stringent access controls. Blockchain technology is heralded as a transformative enabler for meeting 6G standards, owing to its intrinsic attributes. However, a gap exists in the holistic investigation of blockchain's applicability in 6G realms, particularly addressing the “whether”, “when”, and“how” of its deployment. Present research trails in developing robust methodologies to gauge blockchain's efficacy within 6G use cases. Addressing this, our study introduces a novel confluence of blockchain with 6G networks, where data resides in distributed Hash tables(DHTs) while their hashes are secured in distributed ledger technology(DLT), harnessing blockchain's core strengths-immutability, traceability, and fortified security. We delineate seven specific 6G use cases poised for enhancement through blockchain integration,and scrutinize the rationale, nature, and timing of this convergence. Furthermore, we devise a comprehensive methodology for assessing blockchain's performance metrics and scalability in 6G environments. Our extensive experimental analyses evaluate the synergistic performance of this integration, revealing that the Quorum blockchain satisfactorily supports 80% of 6G scenarios. The findings suggest that, with appropriate configurations, consortium blockchains are well-equipped to fulfill the demanding performance and scalability requisites of 6G networks.

可动页岩油综合定量评价是优选研究区有利区块、有利层段、有利岩性组合的基本依据,侏罗系页岩油是四川盆地当前勘探的重点层系,但对其大安寨段页岩油可动性的综合评价和可采层段预测还未见报道。以大安寨段储层为研究对象,通过扫描电镜、低温氮气吸附等微观实验手段,研究不同岩性组合的储集空间、赋存机理及孔隙结构特征;在烃源岩特征基础上,分析大安寨段储层的含油性和吸附差异性;根据基础含油性分析,进一步通过动态岩心实验深入分析目标储层的可动性,并明确其可动性影响因素;最后,通过可动性影响因素分析,依据模糊层次分析法、和积法、平移极差变换法,建立了大安寨段页岩油可动性综合评价指标体系和综合量化方法,筛选了页岩油可动性主要影响因素,优选了大安寨段有利岩性组合,并预测了相应的有利开采层段和可动资源量,通过勘探突破井获得了证实。研究结果表明:大安寨段介壳灰岩致密、泥页岩微裂缝欠发育,含油性最好的纹层状灰质介壳页岩的OSI(即热解游离烃量S1与有机碳含量的比值)可达121.86 mg/g,页岩油可动性最好的是不等厚泥页岩与介壳灰岩互层,其采油指数达34 mg/g。因此,大安寨段可开采的页岩油为互层型/夹层型岩性组合页岩油,致密介壳灰岩顶底板间夹层频率高的大安寨段一亚段下部和大安寨段二a亚段上部、以及大安寨段二b亚段为预测可开采层段,平面上分布在南充—阆中—仪陇—平昌一带、涪陵和三台地区,Ⅰ类有利区页岩凝析油可动资源为1.91×10^(8)t、凝析气可动资源为3232.39×10^(8)m^(3),具有良好的前景。
