Special Issue Information

Dear Colleagues,

The demand for energy, globally, is expected to double to 28 terawatts in about 30 years time. In that time, increasing energy efficiency and developing clean energy sources to protect our environment will become more pronounced. Nanotechnology presents exciting and necessary approaches to address these challenges, while also retaining our energy security. For example, in rechargeable batteries:

  1. Nanostructured carbons and ceramics may improve the reliability and lifetime of electrodes.
  2. Nanoparticles may be superior to sulphur in encouraging lithium or sodium transport during charge-discharge cycles.
  3. Tin sulphide and other 2D nanosheet materials may prove useful compared to nanostructured carbons for better sodium uptake and release characteristics.
  4. Specific nanoparticles may be capable of bi-functional catalysis, namely oxygen reduction and evolution, in metal-air batteries.

Nanoscale phenomena of relevance include the rudimentary steps of energy conversion, such as charge transfer, molecular rearrangement, and chemical reactions. The development of new nanoscale materials, and the methods to characterize, manipulate, and assemble them, enable the development of potent energy technologies. Contributions are solicited in but not limited to contemporary or futuristic nanotechnology for:

  1. Scalable methods to split water with sunlight for hydrogen production
  2. Highly selective catalysts for clean and energy-efficient manufacturing
  3. Harvesting solar energy
  4. Solid-state lighting
  5. Reversible hydrogen storage materials
  6. Fuel cells, batteries, thermoelectrics, and ultra-capacitors

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Materials is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Thermal energy storage can be carried out by working fluid adsorbing and desorbing in porous materials. In this paper, the energy storage properties of four refrigerants, R1234yf, R1234ze, R134a and R32, with M-metal organic framework (MOF)-74 (M = Zn, Ni, Mg, Co) nanoparticles are investigated using molecular dynamics simulations and grand canonical Monte Carlo simulations. The results show that M-MOF-74 can adsorb more R32 and R134a than R1234yf and R1234ze, as the molecular structures of R32 and R134a are smaller than those of R1234yf and R1234ze. Mg-MOF-74 owns a higher adsorbability than the other MOFs. The energy storage properties of the studied refrigerants can be enhanced when the sum of thermodynamic energy change of MOF particles and the desorption heat of fluid in MOFs is larger than the enthalpy change of pure organic fluid. The R1234yf/M-MOF-74 (M = Co, Mg, Ni) nanofluid can store more energy than other refrigerants/M-MOF-74 (M = Co, Mg, Ni) nanofluid. The energy storage enhancement ratios of R1234yf, R1234ze and R134a with Mg-MOF-74 nanoparticles are higher than those of other M-MOF-74 (M = Co, Ni, Zn) materials. Full article

The thermal properties of refrigerants can be modified by adding porous nanoparticles into them. Here, molecular simulations, including molecular dynamics and grand canonical Monte Carlo, were employed to study the thermal energy storage properties of an R161/MOF-5 nanofluid. The results show that the thermodynamic energy change of MOF-5 nanoparticles is linear to the temperature. The adsorption heat calculated by grand canonical Monte Carlo is close to that calculated by the Clausius–Clapeyron equation. Additionally, a negative enhancement of the thermal energy storage capacity of the R161/MOF-5 nanofluid is found near the phase transition area. Full article
