Development of electrospun PVA nanofibers via freeze-thawing method
(Athlone Institute of Technology, 2019)
The polyvinyl alcohol (PVA) hydrogels are proven to have the benefits of improving water retention ability, cell attachment and controlled drug release in
medical device materials for pharmaceutical applications. Due to ...
Yerba mate extract in microfibrillated cellulose and corn starch films as a potential wound healing bandage
(MDPI, 2020-11-27)
Microfibrillated cellulose films have been gathering considerable attention due to their high
mechanical properties and cheap cost. Additionally, it is possible to include compounds within the
fibrillated structure in ...
Oxide layer containing apatite formed on Ti-25Nb-25Ta alloy treated by two-step plasma electrolytic oxidation.
(Elsevier, 2020-01-25)
Hydroxyapatite (HA) is a bioactive calcium phosphate capable of enhancing the implant/bone connection improving osteoconductivity and osseointegration process. However, the HA presents mechanical properties limiting its ...
Evaluation of titanium nitride coatings in bandsaw blades for wood splitting by cold plasma
(Taylor & Francis, 2021-11-06)
Due to the advances in surface treatments, it is possible to obtain excellent cutting tools. However, the field for wood cutting tools still needs to be further investigated. In this work, titanium nitride was deposited ...
Effect of cullulose size-concentration on the structure of polyvinyl alcohol hydrogels.
(Elsevier, 2020-06-11)
Microfibrillated cellulose as a reinforcement agent has been investigated extensively due to their unique characteristics, which can reorder the structure of polymers and hydrogels leading to improved mechanical properties ...
Smart hydrogels: therapeutic advancements in hydrogel technology for smart drug delivery applications.
(Wiley, 2015-12)
Hydrogels are a fusion of solid and liquid phases which closely mimic biological tissue. As such they have enormous potential for drug delivery systems as they are biocompatible and may be tailored to specific applications. ...
Microfibrillated cellulose films containing chitosan and tannic acid for wound healing applications
(Springer, 2021-06-12)
The effectiveness of tannic acid as antimicrobial and wound healing for burns have been shown for a century; however, uncontrolled target dosage may result in undesirable side-effects. Remarkably, tannic acid polyphenols ...
Characterization of gels and films produced from Pinhão seed coat nanocellulose as a potential use for wound healing dressings and screening of Its compounds towards antitumour effects
(MDPI, 2022-07-07)
The reuse of agro-industrial waste assumes great importance today. Pinhão is the seed of
Araucaria angustifolia, which is native to the mountains of southern Brazil, Paraguay, and Argentina.
The coat is a by-product of ...
Titanium-niobium alloys covered by electrospinning technique to applications in bone implants
(Athlone Institute of Technology, 2019)
Recently, to avoid toxic metals in the human environment, there are many efforts to produce alloys containing titanium Ti and niobium Nb. Nb is a powerful stabilizer of
beta-titanium phase[1]. Depending on the composition ...
Development, characterization and cell viability inhibition of PVA spheres loaded with Doxorubicin and 4′-Amino-1-Naphthyl-Chalcone (D14) for osteosarcoma
(MDPI, 2021-08-06)
Chalcones (1,3-diaryl-2-propen-1-ones) are naturally occurring polyphenols with known anticancer activity against a variety of tumor cell lines, including osteosarcoma (OS). In this paper, we present the preparation and ...
