Methods and Electrolytes for Electrodeposition of Smooth Films
Electrolytes which can effectively enhance the smoothness of deposited films during electroplating process are provided. The electrolyte contains a solvent, a metal (M1) salt containing a metal to be deposited, and an additive metal (M2) salt. The cations of the additive salt can be preferentially adsorbed, but cannot be deposited on the protruded region of the deposited film, therefore forms a positively charged electrical shield which covers the protruded region. This self-assembled electrical shield (SAES) will prevent further deposition of metal (M1) in the protruded region so metal (M1) will be preferentially deposited onto the non-protruded region. This self-smoothing process will effectively improve the smoothness of deposited films during electroplating process.

Powering Up to Address Challenges in Energy Storage
In 2006, battery research was practically non-existent at PNNL. Today, the lab is lauded for its battery research. How did PNNL go from a new player to a leader in state-of-the-art storage for EVs and the grid?
Reactor, CO2 sorbent system, and process of making H2 with simultaneous CO2 sorption
A reactor and process for production of hydrogen gas from a carbon-containing fuel in a reaction that generates carbon dioxide is described. The carbon-containing fuel can be, for example, carbon monoxide, alcohols, oxygenates bio-oil, oil and hydrocarbons. In preferred embodiments, the reactor includes a monolithic structure form with an array of parallel flow channels. Methods of using the reactor are also described. In the reactor apparatus of the present invention, the catalytic reaction for hydrogen formation is conducted in conjunction with a carbonation reaction that removes carbon dioxide that is produced by the reactor. The carbonation reaction involves reaction of the carbon dioxide produced from the hydrogen formation reaction with metal oxide-based sorbents. The reactor apparatus can be periodically regenerated by regeneration of the sorbent. A carbon dioxide sorbent system comprising a solid sorbent and a eutectic, mixed alkali metal molten phase is also described.
COMPOSITION FOR PLATING METAL COATINGS AND METHODS OF MAKING AND USING THE SAME (iEdison No. 0685901-23-0215)
As a follow-on from our successful work on electroplating Zr and Ti metal (covered by US patent No. 11,613,825), we have discovered that titanium metal can be electroplated in our system from the chloride salt (TiCl4) in addition to the fluoride salts. Our intern, Bailey Byrd, was a significant contributor to the work but is not an inventor.
