In this study, a highly efficient and simple in situ one-step hydrothermal process is demonstrated to synthesize the yolk-shell [email protected] flower-like hollow MgAl layered double hydroxides (LDH). The morphology analysis further confirmed its unique structure and the [email protected] flower-like hollow MgAl LDH was 2–3 μm in diameter with 10...

Hollow microtubule structured nano-/micromaterials of hollow tubular g-C3N4 (TCN) enwrapped with nanosheets were fabricated by a three-step method. By calcining NiCo-layered-double-hydroxides/tubular-cyanuric acid-melamine (NiCo-LDH/TCM) precursor prepared through using 2-methylimidazole as precipitant and methanol as solvent, the as-prepared [emai...

Left and right single-handed helical polysilane (L-HPS and D-HPS) and racemic helical polysilane (R-HPS) were synthesized by the Wurtz-type coupling reaction. The chiral dichloro(methoxycarbonyl ethyl propyl ether)methylsilane monomers applied in copolymerization were derived from methyl d/l-lactate. The obtained polymers were characterized by ¹H a...

A facile template-free hydrothermal method was proposed to synthesize 3D flower-like hollow Mg-Al layered double hydroxides (LDHs) microspheres. The structure and morphology characterization revealed that 3D flower-like hollow Mg-Al LDHs microspheres with a diameter of about 2.5 μm were assembled with numerous nanosheets. Interestingly, based on th...

... In this work, HTLCs' microsphere with 3D structure was synthesized by one-stephigh-temperature solvothermal method [27] and then modifed by KF·2H 2 O. Te structure and morphology were characterized by several measurements methods, which confrmed its three-dimensional spherical structure. Te prepared catalyst was used for the transesterifcation reaction to produce biodiesel, and the results showed that the catalysts presented excellent catalytic activity. ...
... On the basis of the above evidence, we propose an MA mechanism for the SLF materials, as shown in Figure 9. First, the three-dimensional spherical flower structure creates more interfaces and generates significant interfacial polarization, which leads to more dielectric and magnetic losses [41]. Second, the resulting high specific surface area, along with the numerous pores and spaces, provides multiple reflection and scattering channels, which further enhance the attenuation of incident waves [42]; in addition, the generated three-dimensional interconnected conductive network can provide more conductive paths for electron transport [43]. Third, Fe3O4 anchored on the surface of 3D spherical flower-structured LDHs leads to the existence of multiple heterogeneous interfaces, including those between LDHs and Fe3O4 nanoparticles, those between LDHs and paraffin, and those between paraffin and air, which greatly improves the structure's interfacial polarization capability. ...
... F I G U R E 4 Three different disconnection approaches of Si-Si Bonds. [21][22][23] coupling method has the advantage of high-functional group compatibility, in as much as the reaction conditions are relatively not mild (the reaction is carried out in sodium suspension), numerous substituents are difficult to withstand such reaction conditions. 24 Therefore, the types of substituents in polysilane are limited, which contributes to the difficulty of the polycondensation of many monomers containing reactive functional groups. ...
... Previous studies have demonstrated that different material characteristics can be leveraged to enhance the optical scattering properties of certain materials. Relevant research includes the utilization of 3D flowershaped hollow Mg-Al layered double hydroxide (LDH) microspheres, gradient refractive index layered double-shell nanoparticle optical films, organic silicone beads (OSB) in polycarbonate (PC)/styrene-co-acrylonitrile (SAN) mixtures, polymer-dispersed liquid crystal (PDLC) films, and potassium sodium niobite (KNN) films to achieve excellent light scattering performance and high optical transparency [35][36][37][38][39]. Polycarbonate (PC) or polymethyl methacrylate (PMMA) are commonly used materials for secondary lenses. ...
... In recent years, BHPF has been modified with various functional groups such as alcohols, phenols, epoxies, acrylics, carboxylic acids, and amines. These modified derivatives can undergo addition or condensation reactions with other monomers, leading to the formation of diverse polymer materials with applications in optoelectronics, electronics, and automotive industries [39][40][41][42]. Previous studies conducted by various researchers have investigated the incorporation of bisphenol fluorene derivatives into PLA and explored their impact on the thermal properties of the resulting materials [43,44]. ...
