The DIW of objects with isotropic structural color relies on the design of inks that simultaneously enable 3D shaping and self-assembly of colloidal glasses (Fig.1). Shaping of objects with bespoke color patterns occurs via the top-down deposition of inks of specific compositions using the program...
Yield stress refers to the normal stress when the material yields. Fig. 1a shows the relationship between the viscoelasticity of printing inks mixed with different concentrations of SPI and the oscillatory stress. The storage modulus (G') was much higher than loss modulus (G'') and was ...
Petrochemical: In the petrochemical sector, lithium stearate may be used as an lubricant or release agent. As a catalyst in petroleum cracking, lithium stearate improves cracking yield and efficiency. Lithium Stearate Production Process : Chemical Synthesis: ...
yield stress of the printing ink. As shown above (Fig.2d), PEDOT:PSS inks with concentrations from 0.1 mg mL−1to 20 mg mL−1are applicable for printing free-form hydrogels with complex architectures. The sizes of the ink threads can be readily modulated by adjusting the ...
Laser powder deposition (LPD), as one of the most widely used additive manufacturing methods for metals, is an important rapid prototype manufacturing and
Components produced using nearly all AM processes, encompassing both the PBF and DED methods, as well as casting, yield highly textured dendritic-columnar structures in industrially significant metals such as Al alloys, titanium, and stainless steels [33]. Note that the AM processes viz., ...
Mix-1 showed a maximum yield shear stress and plastic viscosity values (i.e. 56.29 Pa and 17.06 Pa·s), and they gradually decreased to 41.56 Pa and 16.46 Pa·s for Mix-2, and 25.98 Pa and 8.75 Pa·s for Mix-3, respectively. The fresh property enhancement of...
2 prove that it is possible to create overhangs and concave geometries using a shaping ink of sufficiently high yield stress, which significantly reduces the printing time. The cuboids shown in Fig. 4a,c are 15.3 mm high with side lengths of 15 mm. The wall thickness was set to 1.6...
the relationships between the EGaIn volume fraction and both the energy storage modulus and the yield stress can be fitted respectively (Supplementary Fig.10) as:G’ ~ φeff(φeff − 1.51) ΔP, τy~ φeff(φeff − 1.43) ΔP, where ΔP represents the Laplace stress (ΔP...
