Superhydrophobic membrane that is highly resistant to wetting by aqueous solution has gained great attention because of its potential to be applied in many emerging membrane processes such as membrane gas absorption (MGA) and membrane distillation (MD).

Numerous approaches have been proposed to obtain membranes with superhydrophobic surface from materials with various degrees of hydrophobicity. This paper then reviews the progress in superhydrophobic membrane preparation and its separation properties. A brief description of superhydrophobicity is firstly presented. This article could provide an insight for further development of superhydrophobic membrane.*

Borophene: Two-dimensional Boron Monolayer: Synthesis, Properties, and Potential Applications

Reviews Volume 122,

Issue 1, Pages 1000 – 1051, 12 January 2022

Borophene, a monolayer of boron, has risen as a new exciting two-dimensional (2D) material having extraordinary properties, including anisotropic metallic behavior and flexible (orientation-dependent) mechanical and optical properties. This review summarizes the current progress in the synthesis of borophene on various metal substrates, including Ag(110), Ag(100), Au(111), Ir(111), Al(111), and Cu(111), as well as heterostructuring of borophene.

In addition, it discusses the mechanical, thermal, magnetic, electronic, optical, and superconducting properties of borophene and the effects of elemental doping, defects, and applied mechanical strains on these properties. Research and application challenges and the outlook of the whole borophene’s field

Technological solutions for long-term storage of partially used nuclear waste: A critical review

Nuclear power is an ideal option for sustainable energy sources from U-235 fission. However, this energy generates long-term radioactive waste such as partially used nuclear fuel (PUNF) during electricity production. This work reviews various technologies to provide viable, sustainable, and long-term solutions for the PUNF storage.

They include vitrification, partitioning and transmutation (P&T), pyro-processing, and deep geological repository (DGR). Their benefits and drawbacks are evaluated and compared based on previous studies. How to deal with the public perception of DGR and its impacts on the future of nuclear energy and the business opportunities of nuclear storage technology in the global market are discussed. A perspective of recycling nuclear waste into usable fuel is also elaborated.

Our literature survey of 160 published articles (1981–2021) showed that DGR is the most ideal solution for long-term storage of the PUNF, as it provides an ultimate destination in a deep underground that permanently isolates the waste from inhabitants and the environment. Although storing PUNF in a DGR maybe convenient and economical in the short-term, the waste must be stored in a retrievable form so that it can be recycled as a fuel. In the long-term, a complete recycling of used nuclear fuel is the best option. As technological solutions and sound radioactive waste management policy are important for the safe storage of PUNF, stakeholders in the nuclear industry should portray long-term radioactive waste management through viable, feasible, and permanent solutions to waste storage for the sake of public safety and the environment.*
