Abstract Simultaneously engineering the mesoscale mass transfer and surface reactions on the electrode can promote the kinetics of oxygen evolution reaction (OER). Herein, we report the simultaneously modulation of the mesoscale diffusion and Mo-Fe-C sites formation over monodispersed hollow Fe@MoS2-C sub-micro reactors for boosted OER performance. According to finite element simulation and analysis, the hollow nanostructured MoS2-C host possessed much better mesoscale diffusion properties than its solid and yolk–shell counterparts. Notably, the sulfur vacancies and intercalated carbon in the sub-micro reactor offered a unique microenvironment for Fe anchoring on Mo-Fe-C sites. The stability and activity of the sites were revealed by theoretical calculations. The resultant Fe@MoS2-C presented an OER overpotential of 194 mV, which is much better than those of the Fe-based single-atom catalysts reported to data. Our monodispersed sub-micro reactor combined the advantage of mesoscale diffusion and single-atom sites, and it may have broad prospects for complex electrocatalytic reactions.

Abstract The ASME Nuclear Engineering Division (NED), the sponsoring organization for both the creation of the Journal of Nuclear Engineering and Radiation Science and key supporter of Professor Igor Pioro as the Editor-in-Chief of the Journal, is delighted to note that the journal has been successfully publishing high impact technical articles for the benefit of the nuclear community since 2015. In keeping with the NED support of the Journal, and of course NED policy to implement and complement the position and practices of the American Society of Mechanical Engineers, the NED is acting to tailor its organization to better serve the needs of both. Recently the NED Executive Committee (EC) voted to create a flexible and dynamic organizational structure capable of providing timely and comprehensive support for nuclear engineering-related conferences and summits. A major ingredient in the NED organization are NED-lead technical committees focused on current developments and industry-related topics that support the nuclear community, for example centered on advanced reactors, thermal-hydraulics (including computational fluid dynamics as well as verification and validation), and codes and standards, etc. The focus areas for the technical committees are reflected in the track content of the NED sponsored International Conference On Nuclear Engineering (ICONE) each year. The administrative committees will focus on the organization of conferences/meetings as well as the administrative needs of NED. Presently the NED co-sponsors the Small Modular and Micro Reactor Summit (SMMR), and Advanced Clean Energy Summit (ACES) in addition to sponsoring ICONE.

Abstract This article encircles the research progress of Fe3O4 NPs loaded composite microgel particles. Preparation methodologies, properties and applications of Fe3O4 NPs loaded composite microgel particles are elaborated here. The effect of different factors on the stability and tunable properties of Fe3O4 NPs loaded composite microgel particles was also investigated in detail. These composite particles have exceptional magnetic properties that make them demanding composite nano-formulation in different fields. Applications of these composite microgel particles in different fields as micro-reactor, drug delivery vehicles, and in adsorption and catalysis have also been elaborated in detail. These composite microgel particles can easily be recovered from the reaction mixture by applying an external magnet due to the presence of fabricated Fe3O4 NPs.
