    Abstract: Provided herein are methods for making a freeze-cast material having a internal structure, the methods comprising steps of: determining the internal structure of the material, the internal structure having a plurality of pores, wherein: each of the plurality of pores has directionality; and the step of determining comprises: selecting a temperature gradient and a freezing front velocity to obtain the determined internal structure based on the selected temperature gradient and the selected freezing front velocity; directionally freezing a liquid formulation to form a frozen solid, the step of directionally freezing comprising: controlling the temperature gradient and the freezing front velocity to match the selected temperature gradient and the selected freezing front velocity during directionally freezing; wherein the liquid formulation comprises at least one solvent and at least one dispersed species; and subliming the at least one solvent out of the frozen solid to form the material.

    Abstract: An interactive modular device for instructing and assisting users on sample handling processes using features to guide a user through the processes in real time. The modules of the device include a processing module (e.g., pooling module), a sample-container module (e.g., tube module), a container-closure module (e.g., cap module), a sample-transfer module (e.g., pipette module), a scanning module (e.g., single barcode module), a multi-scanning module (e.g., multi-barcode module), a waste container module, and a display module. The features include mechanisms to determine presence and absence of items used for sample handling and visual, audible, and tactile indicators in real time.
