Special Issue Information

Dear Colleagues,

The tight control of the nanoproducts obtained from cellulose destructuring paved the way to several fascinating applications of these materials. The possibility to isolate nanostructured cellulose building blocks with tunable dimensions (ranging from true nanocrystals up to microfibers) have been exploited in several applications: from the tuning of material structural properties to the synthesis of responsive systems and the development of drug delivery systems, to cite a few.

Compared to many other materials used for similar purposes, the use of cellulose nanocrystals (CNC) has several attractive aspects:

1) Cellulose is a renewable source. Thus, it enables a green chemistry approach to developing functional materials;

2) Cellulose nanocrystals (CNC) can be obtained as by-products from a number of industrial processes (i.e., paper, food, textiles). This fact makes it possible to fabricate high-added-value products from industrial scraps and enables a truly circular economy;

3) The chemical inertness of CNC makes it possible to separate and recover them even from complex mixtures them while maintaining their purity.

The development of materials with tailored optical properties requires high control over both physical and chemical properties. In this respect, CNC are of interest since they show high transparency in the visible range, they permit a careful control over their surface chemistry (particularly surface charge density), and they show reproducible shape. In turn, these parameters are used to modulate the interactions among CNC as well as those with external interfaces.

Since the discovery that CNC solutions self-assemble to form birefringent materials, several uses of CNC-based materials in optics have been demonstrated, and this Special Issue will collect contributions aimed at demonstrating that the research of CNC-based materials is lively and continuously innovating. We welcome manuscripts in the form of full papers, communications, and reviews. Potential topics include, but are not limited to:

  1. CNC-based nanomaterials synthesis with peculiar optical properties;
  2. Analysis specifically addressing the optical characterization of CNC materials;
  3. Novel nanotextured/nanostructured surfaces with desired optical response;
  4. Optical sensors based on CNC materials.

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. Nanomaterials 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 2000 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.
