For samples without a catalyst, the storage modulus and tan(δ) curves are almost identical regardless of processing, which agrees well with the previous literature. (2,15,17,25,27,28,31,37,38) In contrast, …
The storage modulus, loss modulus and loss factor of the material first increase and then decrease with the increase of the nozzle temperature, and reach the maximum at about 215 C. Compared with the effect of nozzle temperature on the elastic modulus and tensile strength, the dynamic mechanical properties of the FDM-printed …
Hence, in the following discussion, some fundamentals about polymer rheology, the experimental methods using parallel-plate oscillatory rheometer, and step-by-step guides …
3D printing technologies have gotten an attention as a viable option for future manufacturing. Among them, FDM is the most popular one because it is inexpensive and can process with multiples materials. Layered surface, that has high roughness, is obtained with the technology due to layer-by-layer based process. This result highly …
3D food printing is a digitally controlled process in which food materials are deposited by the number of layers placed one above the other. The extrusion-based printers are commercially used for 3D food printing into the various innovative designs for personalized food products. The present review is compiled based on investigations in …
On the basis of the SFE, the RSM approach was used to optimize the preparation procedure to obtain LEO-NEs with the smallest droplet size. LEO-NEs exhibited good antioxidant activity when the HLB ...
From the dynamic mechanical analysis, we determined the storage modulus (G′), loss modulus (G″) and loss factor (tanδ = G″/G′) to evaluate the …
The slope of the loading curve, analogous to Young''s modulus in a tensile testing experiment, is called the storage modulus, E''. The storage modulus is a measure of …
Under such conditions, the characteristics of plasticization such as changes in T g, tensile properties, storage modulus, and dimensional size cannot be easily …
The storage modulus and glass transition temperature (T g) of CdS/PMMA nanocomposites have been evaluated as a function of concentration of CdS …
While storage modulus demonstrates elastic behavior, loss modulus exemplifies the viscous behavior of the polymer. Similar to static mechanical properties, …
The storage modulus and phase angle of UHMW-PE in Figure 3a, b show characteristic rubbery plateau behavior, with a constant low loss angle indicating elastic behavior, for …
The glassy region at low temperatures was characterized with a relatively weak dependence of the storage modulus on the temperature and low tan δ values (Fig. 1).As the heating continued, a drop in storage modulus and peak of tan δ appeared for all samples, marking the glass transition region where the material losses its stiffness.
The storage modulus and phase angle of UHMW-PE in Figure 3a, b show characteristic rubbery plateau behavior, with a constant low loss angle indicating elastic behavior, for the entire frequency range with a slight nod toward the lower frequencies that might
Temperature-dependent storage modulus of polymer nanocomposites, blends and blend-based nanocomposites was studied using both analytical and experimental approaches. The analytical strategy comprised modeling the thermomechanical property of the systems based on parameters affecting the conversion …

Meat analogues often contain blends of textured and non-textured proteins from soy, wheat or pea, which after processing can be used to create a range of morphologies 7,8.
The post-treatment resulted in an increase in failure temperature, T g and storage modulus obtained via DMA measurements. Similarly, Steyrer et al . observed that the UV post-treatment applied to their DLP samples and observed that the Young''s modulus and tensile strength of the green samples were significantly increased after the …
