Our new paper “Tunable Atomic Layer Deposition into Ultra-High-Aspect-Ratio (>60000:1) Aerogel Monoliths Enabled by Transport Modeling” is published in Chem. Mater. We demonstrate tunable control of the ALD infiltration depth into an aerogel monolith and develop a reaction-diffusion model to accurately describe the coating process. The model allows for co-optimization of the total deposition time Continue Reading »

Solid-state battery perspective published in Joule
Our joint Perspective article with the Sakamoto group at UM was recently published in Joule, entitled “Transitioning solid-state batteries from lab to market: Linking electro-chemo-mechanics with practical considerations”. In this perspective, we consulted with three major automotive manufacturers to identify key challenges in commercialization of solid-state batteries for electric vehicles, including manufacturing, cell design, Continue Reading »
New paper published in Matter
Our paper “Operando Analysis of the Molten Li|LLZO Interface: Understanding How the Physical Properties of Li Affect the Critical Current Density” is published in Matter. We show that solid-state batteries (SSBs) using high-temperature (molten) Li metal anodes can withstand extremely high current densities of 530 mA/cm2, which is an order-of-magnitude higher Continue Reading »
Adrian and Neil win Robert M. Caddell Award
Ph.D. student Adrian Sanchez and Neil Dasgupta were awarded the 2021 Mechanical Engineering Robert M. Caddell Memorial Award for Research. This award is granted to a Faculty/Grad Student team that have jointly made significant contributions to research in materials and/or manufacturing.
New paper on PE-ALD of copper oxide
Our paper “Plasma-Enhanced Atomic Layer Deposition of p-type Copper Oxide Semiconductors with Tunable Phase, Oxidation State, and Morphology” is published in Journal of Physical Chemistry C. We demonstrate a new PE-ALD process for CuOx films using a combination of oxygen and hydrogen plasma. This enables tuning of oxidation state in Cu, which is Continue Reading »

New Battery papers published
We published two new papers on our battery research in December! The first paper, published in Chem. Commun. introduces a new process to form an inorganic-organic hybrid solid electrolyte by Molecular Layer Deposition (MLD), which is an organic analog to ALD. The films are well-behaved as solid electrolytes, with an ionic conductivity of ~5×10 Continue Reading »
New paper in ACS Nano
Our paper “Area-Selective Atomic Layer Deposition Patterned by Electrohydrodynamic-Jet Printing for Additive Manufacturing of Functional Materials and Devices” is published in ACS Nano. We demonstrate that E-jet printing of polymers with sub-micrometer linewidths (down to 312nm) can be used to block ALD deposition with sub-nm precision in the z-direction, representing a new additive nanomanufacturing Continue Reading »
