“…A high-precision servo motor and DC servo system power the cross-head, allowing it to achieve a variable range of speeds across the full load range. (21) Results of flexural strength showed that nanosilver modified veneering porcelain (2904±76.4, 1318±58.1Mpa) on metal and zirconia cores significantly increased their flexural strength compared to their control subgroups (2542±71.9, 1066.8±47.2Mpa) respectively. This increase might be attributed to the presence of ductile silver nanoparticles with a coefficient of thermal expansion higher than that of the glassy matrix, creating radially directed tensile stresses and tangentially directed compressive stresses with the particles.…”

Aim: Evaluation the effect of modification of veneering porcelain bonded to metallic and zirconia cores by silver nanoparticles (SNP) on flexural strength, shear bond strength (SBS), and color change. Materials and methods: A total of sixty samples were constructed and divided into two groups in accordance with the core material type (n=30). Group I: Zirconia core, while group II: Metal core. Each group was classified into 3 sub-groups (n=10) in accordance with the test performed: flexural strength, SBS, and color change, each subgroup was subdivided into two classes (n=5), according to incorporation of SNP. A control class (class I) and Class II: Modified samples. Fracture strength and SBS were tested utilizing a universal testing machine, while color change was measured using a spectrophotometer, Data were tabulated and analyzed statistically. Results: Flexural strength test results showed a significant increase in modified classes on both metallic and zirconia cores (2904±76.4, 1318±58.1MPa) compared to unmodified classes (2542±71.9, 1066.8±47.2 MPa) respectively. Where SBS mean values showed a significant increase in control classes for both metallic and zirconia cores (42.5±0.5, 27.6±0.4 MPa) compared to modified classes (41.4±0.5, 25.7±0.3) respectively. Color change results showed significantly higher mean values (ΔE=10.75±1.1) in Zirconia core group than those in metal group (1.65±0.6). Conclusions: Incorporation of SNP into the veneering porcelain significantly increased flexural strength in both groups while SBS was significantly decreased. Color change of veneering porcelain on metal core was within the acceptable clinical range, while on zirconia core showed higher mean values & was not clinically accepted.

“…Understanding the tensile strength of hydrogel biomaterials is crucial because it determines their ability to withstand mechanical stresses and deformations in biological applications, ensuring the integrity and functionality of these materials in physiological environments [226]. In a tensile test for soft materials, universal testing machine or materials testing machine is used [227]. A representative sample is clamped between specialized grips to prevent slipping.…”

In the last two decades, gelatin-based hydrogels have been widely used as tissue engineering scaffolds due to their excellent biocompatibility, biodegradability, easy processability, transparency, non-toxicity, and reasonable structural similarity to the natural extracellular matrix (ECM). However, intrinsic low mechanical properties of gelatin are not structurally and mechanically suitable to support cell growth and proliferation. That’s why various crosslinking strategies including physical, chemical, enzymatic and combination of them as well as networking patterns including double network, interpenetrating network and nano reinforcing mechanism have been utilized to enhance the structural stability and mechanical integrity of gelatin. In this review, the advances in modulating the mechanical properties of gelatin-based hydrogels for the design and development of structurally stable scaffolds for tissue engineering are discussed. The optimized crosslinking parameters with the adequate mechanical properties of gelatin-based hydrogels are reviewed. Gelatin-based scaffolds for a wide range of tissue engineering applications, such as bone, cartilage, cardiac, skin, and nerve tissue engineering are also outlined. Lastly, current challenges and future perspectives in this research field are presented.

Elastic moduli of 50–250 nm thick Al-50 at % Cu film alloys deposited by thermal evaporation on Kapton substrates and postformed by thermal diffusion are investigated. Formation of the Al2Cu alloy phase was confirmed by X-ray photoelectron spectroscopy (XPS). Surface morphology was examined by atomic force microscopy (AFM) and scanning electron microscopy (SEM) before and after tensile mechanical testing. Force-strain curves of the Al-Cu alloy were obtained by subtracting the effect of the force-strain Kapton curves from the corresponding curves of the Al-Cu/Kapton system. A reduction in the elastic modulus of the Al-Cu alloys from 106.1 to 77.8 GPa with the increase of alloy thickness was obtained. Measured elastic moduli were between the reported bulk modulus for Al and Cu. Reductions in the surface roughness and increments in the grain size were measured after tensile testing of the Al-Cu alloys.
