Special Issue Information

Dear Colleagues,

Composite materials are now established as an essential part of our technological advances, and our practical applications, due to their outstanding mechanical response and tailor-made properties. Polymer composites are nowadays, a well-recognized family of composites, characterized by ease in manufacture, low cost, established processing methods, and varied applications ranging from daily-use issues to highly complicated electronics and advanced medical combinations. Also, nanocomposites made available with graphene and other types of advanced ceramic or organic nanoparticles, are into play in the late years.

This special issue shall focus on the most important fabrication techniques for polymers and polymer- composites in biomedical applications such as electrospinning, melt-extrusion, solution mixing, and melt spinning technologies, as well as in situ methods. Additive manufacturing techniques, such as various 3D printing methods, which have also facilitated the use of smart polymers and some types of filled composites in the families of medical technologies are also of great interest.

Finally, recent progress in biomedical applications and technologies are promoted, such as tissue engineering (including bone, blood vessels, oral tissues, and skin), maxillofacial, plastic surgery, dental resin-based composites, and wound dressing -healing materials as well as smart bio-implants.

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.

Proton pencil beam scanning is a dynamic beam delivery technique with excellent conformability to the tumor volume. The accuracy of spot size and scanning positions will have a significant effect on the delivered dose distribution. We employed polymer gel dosimeters to measure the spot size and the scanning positions for the Shanghai Advanced Proton Therapy facility (SAPT). Polymer gel dosimeters (MAGAT-f and PAGAT) were utilized to measure the full width at half maximum (FWHM) of the beam spot at various depths on the basis of their MRI readouts. The correlation between the spot FWHM and standard deviation (σ) was analyzed at different depths. The measured Bragg peak range was compared with the Monte Carlo (MC) simulation. Three-dimensional volume rendering of the Bragg peak was reconstructed for the 3D visualization to measure the spot size three-dimensionally. The R2 dose–response curve was investigated with polymer gel dosimeters. The deviations of the Bragg peak ranging between measurement and simulation were 0.13% and −0.53% for MAGAT-f and PAGAT, respectively. Our results ascertain the feasibility of a polymer gel dosimeter to measure the spot size and positions of a proton pencil beam. Full article

The impact of metabolic syndrome (MS) on stent performance and outcomes of patients underwent percutaneous coronary intervention (PCI), including stent implantation, had not yet been fully established. The aim of the present study was to investigate long-term safety and efficacy of 2nd generation DES vs. other stent types in MS patients underwent successful PCI for an acute coronary event. Descriptive epidemiology, angiographic characteristics and one-year clinical outcomes, including major adverse cardiovascular events (MACE) and target lesion revascularization (TLR) procedures were evaluated according to the stent type inserted for 204 patients. The occurrence of TLR (6.62% vs. 9.43%, p = 0.50) and the composite outcomes (20.52% vs. 24.52%, p = 0.54) did not differ significantly between patients having 2nd generation drug eluting stents (DES) or other stent types implanted at the index procedure. It seems that the PCI in acute coronary syndrome (ACS) is similarly efficient regardless of the stent type, suggesting that for the treatment of ACS in MS patients, all stent types show similar results, in terms of TLR or MACE.
