Improving microparticle arrays for engineering applications: A new technique using tiny microwells pushes the precision and scalability of microparticle arrays to a new extreme. The assembly includes empty porous microwell arrays (top left) and unassembled microparticles (top middle). A close view of the microparticles in arrays appears at top right, and a wide view of the assembly appears below.

A better way to assay

New design of large-scale microparticle arrays can make materials science and bioengineering applications more scalable, precise, and versatile.

MPC-CMSE Summer Scholar Victoria Yao shows a mixture of sodium thiosulfate being stirred in a solution of copper hexacyanoferrate where its reacts to produce larger compounds that can be filtered out of the solution. These compounds are being developed for use in electrodes for a water-based flow-driven battery for grid level storage.

At right, scanning electron microscope (SEM) images show the two types of lithium deposits, the bulky, mossy type (at top), which grows from its base, and the needle-like dendritic type (bottom), which grows from the tips. At left, SEM images show the effect of a blocking layer of ceramic material that limits the growth of the mossy deposits.

In batteries, a metal reveals its dual personality

Branchlike deposits grow on lithium electrode surfaces in two ways, one much more damaging.

The process of making a stack of parallel sheets of graphene starts with a chemical vapor deposition process (I) to make a graphene sheet with a polymer coating; these layers are then stacked (II), folded and cut (III) and stacked again and pressed, multiplying the number of layers. The team used a related method the team to produce scroll-shaped fibers.

Borrowing from pastry chefs, engineers create nanolayered composites

Method to stack hundreds of nanoscale layers could open new vistas in materials science.
