magnesium and its alloys are light, biodegradable, biocompatible metals that have promising applications as biomaterials. magnesium is potentially useful for orthopedic and cardiovascular applications. however, the corrosion rate of this metal is so high that its degradation occurs before the end of the healing process. one of the ways to improve the corrosion rate is to compose it’s with ceram...
A novel collagen-based bio-composite was constructed from micro-crimped long collagen fiber bundles extracted from a soft coral embedded in alginate hydrogel matrix. The mechanical features of this bio-composite were studied for different fiber fractions and in longitudinal and transverse loading modes. The tensile modulus of the alginate hydrogel was 0.60±0.35MPa and in longitudinal collagen-r...

PURPOSE The objective of this study was to compare osteoconductivity and biodegradation properties of an in-house fabricated beta-tricalcium phosphate (b-TCP)-collagen composite with those of Bio-Oss Collagen® (Osteohealth, Shirley, NY, USA) using a rat calvarial critical-size defect model. MATERIALS AND METHODS b-TCP-collagen composite material was fabricated by mixing b-TCP granules having ...
A Chitosan/sucrose/polyurethane composite bio-membrane was prepared by the facile drop coating method. The composite bio-membrane had a porous spongy structure composed of a physical mixing of each component. The water absorbability of the composite bio-membrane increased with increasing chitosan and sucrose contents. Furthermore, the composite bio-membrane with immobilized Aspergillus sojae ex...
Many bio-based materials, which have lower environmental impact than traditional synthetic materials, show good sound absorbing and sound insulation performances. This review highlights progress in sound transmission properties of bio-based materials and provides a comprehensive account of various multiporous bio-based materials and multilayered structures used in sound absorption and insulatio...
Nanofiber scaffolds and bio-ceramic nanoparticles have been widely used in bone tissue engineering. The use of human induced pluripotent stem cells (hiPSCs) on this scaffold can be considered as a new approach in the differentiation of bone tissue. In the present study, a polyaniline-gelatin-polycaprolactone (PANi-GEL-PCL) composite nanoscaffold was made by electrospinning and modified superfic...
The human skin hosts an array of sensors that are capable of detecting and interpreting many traits important to how we function and survive. The goal of mimicking this capability in composites to create intelligent composite materials has led to the development of a bio-inspired stretchable network composed of numerous micro-fabricated sensors capable of detecting multiple stimuli. The compone...
Designing bio-inspired, multifunctional organic-inorganic composite materials is one of the most popular current research objectives. Due to the high complexity of biocomposite structures found in nacre and bone, for example, a one-pot scalable and versatile synthesis approach addressing structural key features of biominerals and affording bio-inspired, multifunctional organic-inorganic composi...
چکیده سابقه و هدف polyetheretherketone یک پلیمر نیمه کریستالینی با عملکرد عالی است که در ساخت پروتزهای دندانی تحت عنوان bio hpp به کار گرفته شده است. نسل قبلی آن نیز، bio xs از گروه پلی اترکتون ها بوده ولی فاقد فیلرهای سرامیکی بوده است. در راستای ارزیابی ادعای سازندگان درباره ی خصوصیات مکانیکی این رزین ها؛ تحقیق حاضر با هدف مقایسه ی استحکام خمشی و کششی رزین های ترموپلاستیک bio hpp و bio xs د...
