Special Issue Information

Dear Colleagues,

The development and processing of nanomaterials put forward new horizon and opportunities for biological and chemical separation, catalysis, sensor, monitoring, medicine, therapy, energy storage, etc., which makes it play a more and more important role in pursing advanced technology, better quality of life, and sustainable society. Liquid phase, as a typical environment for nanomaterials synthesis and processing, has merits of high capacity, mild conditions, excellent flexibility, and good controllability, which are not only suitable for biological systems specifically, but also guaranteed to achieve environment friendly and commercial production. This special issue seeks to showcase research papers and review articles that focus on the nanomaterials synthesis and processing in liquid phase towards various application fields. The synthesis methods could be nanoprecipitation, hydro/solvo-thermal decomposition, micro-emulsion method, phase conversion, liquid phase exfoliation, etc. The processing methods could be surface modification, encapsulation, doping, self-assembly, hydrothermal treatment, liquid phase deposition, etc. The contributions involving application performances are highly welcome.

The synthesized compound was characterized by 31P, 13C, and 1H NMR spectroscopy and MALDI-TOF mass spectroscopy. According to DSC data, the compound was initially crystalline, but the crystal structure was defective. The crystals suitable for X-ray diffraction study were prepared by slow precipitation of the compound from a solution by a vapor of another solvent. A study of the single crystal obtained in this way demonstrated that the phosphazene ring has a flattened chair conformation. It was found that the sphere circumscribed around the compound molecule has a diameter of 2.382 nm. Full article

Abstract
The effect of external hydrostatic pressure on the hydrothermal synthesis of the microporous silicoaluminophosphate SAPO-18 has been explored. The crystallization of the SAPO-18 phase is inhibited at 150 °C under high pressures (200 MPa) when using relatively diluted synthesis mixtures. On the contrary, [...] Read more.
The effect of external hydrostatic pressure on the hydrothermal synthesis of the microporous silicoaluminophosphate SAPO-18 has been explored. The crystallization of the SAPO-18 phase is inhibited at 150 °C under high pressures (200 MPa) when using relatively diluted synthesis mixtures. On the contrary, the use of concentrated synthesis mixtures allowed SAPO-18 to be obtained in all the studied conditions. The obtained solids were characterized with XRD, SEM, ICP-AES, TG and 27Al and 31P MAS NMR spectroscopy. The results highlight the importance of the external pressure effect on the hydrothermal synthesis of molecular sieves and its influence on the interaction between the organic molecule and the silicoaluminophosphate network.

Fe3O4 nanoclusters have attractive applications in various areas, due to their outstanding superparamagnetism. In this work, we realized a one-step flow synthesis of Fe3O4 nanoclusters, within minutes, through the sequential and quantitative introduction of reactants and modifier in a microflow system. The enhanced micromixing performance enabled a prompt and uniform supply of the modifier oleic acid (OA) for both nanoparticle modification and nanocluster stabilization to avoid uncontrolled modified nanoparticles aggregation. The size of the nanoclusters could be flexibly tailored in the range of 50–100 nm by adjusting the amount of OA, the pH, and the temperature. This rapid method proved the possibility of large-scale and stable production of magnetic nanoclusters and provided convenience for their applications in broad fields. Full article
