Stereolithography (SL) is a technique allowing additive manufacturing of complex ceramic parts by selective photopolymerization photocurable suspension containing monomer, photoinitiator, and powder. The manufactured three-dimensional object cleaned converted into dense part thermal debinding the polymer network subsequent sintering. most critical time-consuming step, often source cracks. In this study, alumina suspensions have been developed, influence resin composition on defect formation...
Abstract Current research on surface modifications has yielded advanced implant biomaterials. Various have been shown to be promising in improving bone target cell response, but more comprehensive studies whether certain can directly behavioural features such as morphogenesis and proliferation are needed. Here, we studied the response of primary alveolar cells various terms osteoblast morphology vitro. Analyses led surface-related test parameters including topographical micro-roughness,...
Bioactive composites, where the deleterious reactions between hydroxyapatite and composite matrix (in this case zirconia) are kinetically inhibited by employing a super-fast consolidation technique, spark plasma sintering (SPS), reported. The materials (see Figure) shown to be 5–7 times stronger 4–7 tougher than monolithic ceramics.
Magnetic [email protected]3O4 micro particles were synthesized by coating nanosized Mg-Al double oxides onto Fe3O4 particles. The formed hierarchical structure gave a high active surface area, which enabled these to work efficiently as catalyst in the glycolysis of poly(ethylene terephthalate) (PET). bis(hydroxyethyl) terephthalate (BHET) yield reached above 80 mol% presence 0.5 wt% reaction system within 90 min at 240 °C. After reaction, was easily retrieved magnetic decantation and can be...
This study centers on investigating the influence of conductive additives, carbon black (Super P) and graphene, within context LiFePO4 (LFP)-impregnated fibers (CFs) produced using powder impregnation method. The performance these additives was subject to an electrochemical evaluation. findings reveal that there are no substantial disparities between two at lower cycling rates, highlighting their adaptability in conventional energy storage scenarios. However, as rates increase, graphene...

Gelcasting of zirconia with agarose as a gelling agent was evaluated, and the rheological behavior suspensions studied. For certain compositions, viscosity low enough for to be processed well sufficient wet green strength avoid deformation cast components due mechanical stresses obtained. Futhermore, it possible increase storage modulus material by reduction gelation temperature, which facilitated demolding. Sintered densities above 99% were achieved high bending The results show that...
Abstract Plasma-treatment of oral implant biomaterials prior to clinical insertion is envisaged as a potential surface modification method for enhanced healing. To investigate putative effect plasma-functionalized on tissue cells, this investigation examined the response alveolar bone osteoblasts and gingival fibroblasts clinically established zirconia- titanium-based surfaces soft integration. The were either functionalized with oxygen-plasma in plasma-cleaner or left untreated controls,...
Composites of zirconia and hydroxyapatite (OHAp) have been processed via hot isostatic pressing (HIP) or sintering in air. When the composites were sintered air at a temperature 950°C, decomposition OHAp to tricalcium phosphate occurred. Using HIP technique, without any detectable degradation phase produced 1200°C. The reactivity between was dependent on both amount water lost from geometry interaction. composition materials prepared evaluated their powder X‐ray diffraction patterns,...

Abstract The development of long‐lasting zirconia‐based ceramics for implants, which are not prone to hydrothermal aging, is satisfactorily solved. Therefore, this study conceived as an overall evaluation screening novel ceria‐stabilized zirconia–alumina–aluminate composite (ZA 8 Sr ‐Ce11) with different surface topographies use in clinical applications. Ceria‐stabilized zirconia chosen the matrix material, due its lower susceptibility aging than yttria‐stabilized (3Y‐TZP). This assessment...
A structural battery is a multifunctional that can carry load while storing energy. Structural batteries have been cutting-edge research focus in the last decade and are mainly based on polyacrylonitrile (PAN)-carbon fibers (CFs).
