Composite cryogels for dual drug delivery and enhanced mechanical properties.
(Wiley, 2018-04)In this study, we present a simple and effective process that integrates hydrogels with drugs + ceramics via physical crosslinks resulting in improved mechanical properties. These cryogels have the potential for controlled ... -
Extraction method plays critical role in antibacterial activity of propolis loaded hydrogels.
(Elsevier, 2016-03)Extracted propolis has been used for a long time as a remedy. However, if the release rate of propolis is not controlled, the efficacy is reduced. To overcome this issue, extracted propolis was added to a cryogel system. ... -
A novel pH‐sensitive ceramic‐hydrogel for biomedical applications.
(Wiley, 2015-12)Innovations on the field of smart hydrogels are now being held with loads of advantages. With recent progress, smart polymers can now be used on the market for specific target/objectives desired on medicine. However, the ... -
Halloysite nanotube reinforced polylactic acid composite.
(Wiley, 2017-10)Polylactic acid (PLA) has long history in medical applications, and reinforced PLA has the potential to be used in the medical applications that require high mechanical strength such as coronary stents and bone fixation ... -
Synthesis and characterization of high density polyethylene / peat ash composites.
(Elsevier, 2016-06)A new type of polymer composite was synthesized from one industrial waste, peat ash, at varying mixing ratios of high density polyethylene (HDPE) and the resulting products were characterized using different experiments ... -
Characteristics of the treated calcium carbonate particles with stearic acid using different treating methods.
(Elsevier, 2016-08)Calcium carbonate (CaCO3) is often treated with stearic acid (SA) to decrease its polarity. However, the method of application of the SA treatments has a strong influence on their interface structure and distribution. ... -
Extended release of proteins following encapsulation in hydroxyapatite/chitosan composite scaffolds for bone tissue engineering applications.
(Elsevier, 2018-03)Highlights: Biocompatible, mechanically robust scaffold with an appropriate stability for bone healing when used with fixation device. Proteins can be covalently attached to the scaffold. Proteins are released for an ... -
Surface modified halloysite nanotubes reinforced polylactic acid for use in biodegradable coronary stents.
(Wiley, 2019-08)Poly(lactic acid) (PLA) was reinforced halloysite nanotubes (HNTs) in this study. To improve dispersion and interfacial adhesion of HNTs within the PLA matrix, HNTs were surface modified with 3‐aminopropyltriethoxysilane ... -
Photopolymerization for filling porous ceramic matrix: improvement of mechanical properties and drug delivering behaviour.
(Wiley, 2019-04)This work presents the photopolymerisation of composite scaffolds where a prefabricated ceramic scaffold was impregnated with poly(ethylene) glycol dimethacrylate (PEGDMA) macromonomer solution. The PEGDMA solution penetrates ... -
Review of multifarious applications of Poly (lactic acid)
(Taylor & Francis, 2016)Poly (lactic acid) is considered to be a promising alternative to petroleum-based polymers due to its renewability, biodegradability, biocompatibility, and good mechanical properties. Because of the high cost, the applications ... -
Bioactive composites fabricated by freezing-thawing method for bone regeneration applications.
(Wiley, 2016-04)Hydrogels are widely used for controlled delivery of therapeutic agents. However, hydrogels lack bioactivity to encourage bone formation and mechanical integrity. Moreover, chemically crosslinked hydrogels exhibit cytotoxic ... -
Alfa fiber/polypropylene composites: Influence of fiber extraction method and chemical treatments.
(Wiley, 2019-01)Alfa fiber/polypropylene composites were manufactured using twin-screw extrusion. Fibers were extracted following alkaline and steam explosion methods. Three chemical treatments were also applied to alkaline extracted ... -
Durum wheat seed germination response to hydrogel coatings and moisture under drought stress.
(Science Publications, 2016-11)Abstract: Technologies that can increase crop production while maintaining low pollution are essential for sustainable agriculture. This study compares the germination performance of Durum wheat seeds (Triticum durum ... -
