Special Issue Information

Dear Colleagues,

We are delighted to launch a Special Issue entitled “Microstructures and Mechanical Behavior of Emerging Hybrid Composites”. This Special Issue is focused on covering the mechanical behavior of advanced monolithic composites and hybrid composites ranging from coarse to micron- and nano-scale reinforcements and/or matrices. Manuscripts addressing the correlation of microstructural evolution with the performance of composite materials are most welcome. The main goals of this Special Issue are to collect original research articles emerging from experimentation and modeling studies, as well as comprehensive review articles in the field of emerging composite materials, including polymer matrix composites, metal matrix composites, ceramic matrix composites, high-entropy composites, oxide-dispersed composites, and composite materials related to energy production and storage. Authors are encouraged to submit their works involving tensile, flexural, compression, shear, torsion, creep, fatigue, hardness, and any severe plastic deformation tests. Further, authors are encouraged to demonstrate the mechanical performance of materials relating to various characterization methods, namely, optical microscopy, advanced electron microscopy, and X-ray diffraction. In addition, we welcome papers modeling composite materials using finite element, discrete element, numerical, and optimization methods. Original full-length research articles, short communications, and review articles will be subjected to peer reviewed by eminent researchers working in the field before acceptance.

With immense pleasure, we invite authors to submit their original scientific contributions to this Special Issue.

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 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. Applied Sciences 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.

The importance of the Eudragit® E100 copolymer (E100) is recognized in the pharmaceutical industry as a pH-dependent coating material in conventional oral administration dosage applications, where a modified release profile is required. On the other hand, its arrangement for 3D printing of cylindrical-shaped filaments containing drugs (to produce customized pharmaceuticals), is still scarce in the literature, and is currently an open field of research. One of the main challenges involves the manufacture of filaments that are flexible and functional, as their cylindrical shape (which is necessary for its use on FDM 3D printers) significantly increases the material’s fragility. Thus, the objective of this work was to prepare and characterize E100/Hesperidin (Hsp) filaments, and to study in vitro dissolution from Hsp active molecules of this unconventional polymeric matrix. The hybrid filaments were produced using a surface chemical treatment of the material resulting from a hot-melt extrusion process. The microstructural characterization of the filaments was performed using SEM, XRD, FTIR and ATR. The thermal analysis of the materials was performed using DSC, and the mechanical resistance was analyzed using flexural testing. The in vitro release profiles of the filament-arranged drug were evaluated in solutions of simulated gastro and intestinal fluids. Full article
