Applications and Theoretical Studies of Low-Dimensional Nanomaterials

Dear Colleagues,

Low-dimensional nanomaterials, including zero-dimensional (0D) quantum dots, one-dimensional (1D) nanowires and nanotubes, and two-dimensional (2D) nanosheets and layered materials, have attracted significant scientific and technological interest due to their unique size-dependent properties. Quantum confinement effects, strong surface activity, tunable band structures, and reduced dimensionality endow these materials with exceptional electronic, optical, magnetic, mechanical, and catalytic characteristics. Rapid advances in synthesis strategies, atomic-scale characterization techniques, and theoretical modeling have enabled unprecedented control over their structure and functionality. Nevertheless, challenges remain in understanding fundamental mechanisms, improving stability and scalability, and achieving predictive material design for real-world applications.

This Special Issue aims to collect high-quality original research articles and comprehensive reviews that explore both the theoretical foundations and practical applications of low-dimensional nanomaterials. In line with the scope of Nanomaterials, contributions addressing synthesis, processing, functionalization, characterization, modeling, and device integration are particularly encouraged. We especially welcome interdisciplinary studies that combine computational simulations with experimental validation, providing mechanistic insights and guiding rational material design. The goal of this Special Issue is to bridge fundamental understanding with technological innovation and to promote the development of next-generation nanoscale materials for advanced applications.

Topics of interest include, but are not limited to, the following:

• Density functional theory (DFT), first-principles calculations, and multiscale simulations;
• Theoretical investigations of electronic, optical, thermal, and magnetic properties;
• Quantum confinement effects and excitonic phenomena;
• Controlled synthesis and scalable fabrication of 0D, 1D, and 2D nanomaterials;
• Surface engineering, defect modulation, and doping strategies;
• Van der Waals heterostructures and emerging 2D materials beyond graphene;
• Advanced characterization techniques at the nanoscale;
• Energy conversion and storage applications (batteries, supercapacitors, photovoltaics, photocatalysis);
• Nanoelectronics, optoelectronics, and flexible devices;
• Catalysis, environmental remediation, sensing, and biomedical applications.

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 submissions that pass pre-check are 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 250 words) can be sent to the Editorial Office for assessment.

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. Nanomaterials is an international peer-reviewed open access semimonthly 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 2400 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.
