“…Porosity refers to the empty spaces between nanofiber components. These pores are located on the surface or inside of nanofibers, making them very lightweight and providing a large surface area ( Roodbar Shojaei et al, 2019 ; Yousefzadeh and Ghasemkhah, 2019 ). Porous nanofibers can be used in the fields of filtration, gas separation, energy, sensor, and tissue engineering.…”

“…Porous nanofibers can be used in the fields of filtration, gas separation, energy, sensor, and tissue engineering. According to the American Society for Testing and Materials (ASTM), the porosity of nanofibers can be measured by different methods such as mercury porosimetry, liquid extrusion porosimetry, capillary flow porometry (CFP), and nuclear magnetic resonance (NMR) ( Roodbar Shojaei et al, 2019 ). Porosity is an important parameter when selecting the scaffold for tissue engineering.…”

“…Raman spectroscopy is typically complemented by infrared (IR) spectroscopy ( Horzum et al, 2019 ). Raman spectroscopy has been widely used to investigate the considerable variations and other low-frequency modes in the distribution of polymers within polymeric nanofiber matrices and to assess the effects of carbonaceous or nanostructured materials on the morphology and physical properties of the electrospun nanofibers ( Chipara et al, 2013 ; Kotzianová et al, 2016 ; Roodbar Shojaei et al, 2019 ).…”

Nanotechnology is one of the most promising technologies available today, holding tremendous potential for biomedical and healthcare applications. In this field, there is an increasing interest in the use of polymeric micro/nanofibers for the construction of biomedical structures. Due to its potential applications in various fields like pharmaceutics and biomedicine, the electrospinning process has gained considerable attention for producing nano-sized fibers. Electrospun nanofiber membranes have been used in drug delivery, controlled drug release, regenerative medicine, tissue engineering, biosensing, stent coating, implants, cosmetics, facial masks, and theranostics. Various natural and synthetic polymers have been successfully electrospun into ultrafine fibers. Although biopolymers demonstrate exciting properties such as good biocompatibility, non-toxicity, and biodegradability, they possess poor mechanical properties. Hybrid nanofibers from bio and synthetic nanofibers combine the characteristics of biopolymers with those of synthetic polymers, such as high mechanical strength and stability. In addition, a variety of functional agents, such as nanoparticles and biomolecules, can be incorporated into nanofibers to create multifunctional hybrid nanofibers. Due to the remarkable properties of hybrid nanofibers, the latest research on the unique properties of hybrid nanofibers is highlighted in this study. Moreover, various established hybrid nanofiber fabrication techniques, especially the electrospinning-based methods, as well as emerging strategies for the characterization of hybrid nanofibers, are summarized. Finally, the development and application of electrospun hybrid nanofibers in biomedical applications are discussed.

Nanofibers (NF) and nanoparticles are attractive in the field of drug delivery especially to improve the drug bioavailability and administration. Easy manipulation of polymeric fibers as macroscopic bulk material may give rise to potential uses as implantable local drug delivery platforms. In this study, poly(ethylene glycol) polyethyleneimine (mPEG: PEI) copolymer blended poly ε-caprolactone (PCL) nanofibers, NFblend accommodating mesoporous silica nanoparticles (MSN) as the implantable local drug delivery system was achieved by employing spin coating and cold atmospheric plasma (CAP) post-processing. The morphology and wettability, mechanical properties, and in vitro cytocompatibility features of NFblend ensured its features as a potential implantable local drug delivery system. The electron microscopy images affirmed the macropores on NFblend are still accessible and claimed the random nanofiber alignment of the NFblend after MSN accommodation may promote cell attachments. Furthermore, the drug release profile from the NFblend and in vitro cytocompatibility and scaffolding features for cell attachment were determined. The sustained drug release profile for 48h was provided regardless of MSN impairment from mat and bulk degradation. The accumulation of curcumin loaded MSN (MSN@Cur) onto NFblend by CAP-assisted spin coating promote cell proliferation compared to its non-treated counterparts. All in all, the obtained NFblend-MSN@Cur nanofiber mats have a high potential to be employed as an implantable local drug delivery system.

Censoring schemes have received much attention over the past decades. Hybrid censoring schemes are censoring schemes mixed of type-I (T-1) and type-II (T-2) censoring schemes, a most popular area of study in life-testing or reliability experiments. More precisely, hybrid censoring can be described as a mixture of T-I and T-2 schemes. Gamma distribution is widely used, and its connection has more distributions. Mixture and single gamma distribution will be studied to estimate parameters, based on type-II hybrid censoring schemes (T-2HCS). We will apply algorithms to compute the maximum likelihood (ML) estimators and Bayesian approaches, using statistics, such as Markov chain Monte Carlo methods. Bayes estimators and corresponding highest posterior density confidence intervals will be tabled. Also, Markov chain Monte Carlo simulation is implemented to compare the performances of the different methods and the real dataset is analyzed for illustrative purposes.
