Hydrogel surface properties can be modified to form bioactive interfaces modulate the osteogenic differentiation of stem cells. In this work, a hydrogel made gelatin methacrylamide (GelMA) and alginate was designed tested as scaffold control stem-cell differentiation. The hydrogel's treated with polydopamine (pDA) create an adhesive layer for adsorption osteoinductive drug dexamethasone (Dex). presence pDA coating enhanced Dex retention over 21 days. This effect resulted in delay hASCs...
Purpose: Selective laser sintering (SLS) is a rapid pro- totyping technique applied to produce tissue-engineer- ing scaffolds from powder materials. The standard scanning technique, however, often produces struts of extensive thickness, which means fabrication high- ly porous with small overall dimensions quite difficult. Nevertheless, this study aims overcome shortfall. Design/methodology/approach: To end, three methods were evaluated in terms minimum feature size and freedom design, using...
In the first part of this paper results a literature review are presented. An overview oxidation behaviour in air and combustion environments both pure MoSi2 composites temperature range from 400 to 1650°C is given. The second reports about our tests with selected (containing 15 vol.-% Al2O3, Y2O3, ZrO2, HfO2, SiC, TiB2, ZrB2, or HfB2, respectively) different development stages at temperatures pest region as well up 1700°C. third describes optimised developed on basis II.
Selective laser sintering (SLS) has the potential to fabricate bioresorbable polymer / ceramic composite scaffolds with pre-designed external and internal architecture that can be used for bone tissue engineering applications. Scaffolds were fabricated using poly-ε-caprolactone as base material. The effect of 15 30 wt% hydroxyapatite (HA) addition was investigated in terms compressive properties, accuracy, surface topology, wettability. Fabricated dimensions PCL microstructures showed great...
Breast cancer is one of the most common cancers in women. In United States alone, it accounts for 31% new cases, and second only to lung as leading cause deaths American More than 184,000 cases breast are diagnosed each year resulting approximately 41,000 deaths. Early detection intervention significant factors improving survival rates quality life experienced by sufferers, since this time when treatment effective. One promising imaging modalities microwave imaging. The physical basis active...
Microspheres, synthesized from diverse natural or synthetic polymers, are readily utilized in biomedical tissue engineering to improve the healing of various tissues. Their ability encapsulate growth factors, therapeutics, and biomolecules, which can aid regeneration, makes microspheres invaluable for future clinical therapies. While microsphere-supplemented scaffolds have been investigated, a pure microsphere-based scaffold with an optimized architecture has challenging create via 3D...

Part III: Oxidation behaviour of optimised MoSi2 composites The topic "Oxidation particle reinforced at temperatures up to 1700°C" is discussed in a three part publication. In the first this paper literature survey on oxidation and has been given. second an initial screening 1600°C revealed those which may be suitable for high temperature applications. low selected "pest" region was examined as well. Additionally, effect iron impurities explained. present deals with detailed investigation...
The assortment of low-cost 3D printers for “in-practice” use, e.g., clear aligner therapies, is ever increasing. To address concerns about the accuracy orthodontic models produced on such when cost efficient modes printing are employed, this study examined effect print model body type and angulation accuracy. Six printing-configuration groups were included: 2 types (solid or hollow shell) combined with 3 angles (0°, 70°, 90°) 10 models/group; all printed 100-µm layer thickness using a...

Abstract In the first part of this paper a literature survey on oxidation behaviour MoSi 2 and composites has been given. The present second reports about experimental results from tests with several containing 15 vol.‐% Al O 3 , Y ZrO HfO SiC, TiB ZrB or HfB respectively, different development stages. were conducted at 1600°C in air for 100 hours. It was shown that production route powders significant influence performance materials high temperatures. This attributed to contaminations....
