3D printing and freeze casting hierarchical mxene pressure sensor
Nanocomposites, 2023 Although MXene sheets are highly conductive, it is still challenging to prepare MXene complex functional materials for flexible electronics by simple and effective methods. In 3D printing, especially direct ink writing (DIW), different materials are used

Photoacoustic monitoring of freezing-induced loading and freeze-casting processes. [PDF]
Biomed Opt ExpressBoth freezing-induced loading (FIL) and freeze-casting (FC) are used for nano- and microstructured materials fabrication, including core-shell structures, shells, porous materials, as well as ceramics. The crystallization front velocity is a critical parameter for these techniques because it defines the period of lamellar structure during FC and FIL ...

Ultrasonic Transducers Made From Freeze-Cast Porous Piezoceramics [PDF]
IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2022 Porous and composite piezoelectric ceramics are of interest for underwater ultrasonic transducers due to their improved voltage sensitivity and acoustic matching with water, compared with their dense counterparts. Commonly, these materials are fabricated by dice-and-fill of sintered blocks of polycrystalline piezoceramic, which results in a high volume

Effect of cooling rate on the microstructure and porosity of alumina produced by freeze casting [PDF]
Journal of the Serbian Chemical Society, 2012 Freeze casting is a well-known shaping technique to produce materials with directional porosity. One of the major problems is the difficulty to control the cooling rate thus leading to gradients in pore size and homogeneity.

Biomimetic Materials by Freeze Casting [PDF]
JOM, 2013 Natural materials, such as bone and abalone nacre, exhibit exceptional mechanical properties, a product of their intricate microstructural organization. Freeze casting is a relatively simple, inexpensive, and adaptable materials processing method to form porous ceramic scaffolds with controllable microstructural features. After infiltration of a second
