Latest Patents

McLarnon's latest patents include innovations in photochromic, electrochromic, photoelectrochromic, and photovoltaic devices. One of his key inventions is a light-activated photoelectrochromic device that consists of a two-component system made up of a photoactive charge carrier generating material and electrochromic material, along with an electrolyte. This device allows light to interact with a semiconductive material, generating hole-electron charge carriers that initiate a redox reaction in the electrochromic material. Notably, one configuration utilizes hydrated nickel oxide as the electrochromic layer and polycrystalline titanium dioxide as the charge generating material. The design can be implemented with discrete layers or mixed materials, eliminating the need for an external circuit to drive the electrochromic reaction, although one can be used to enhance the process. Additionally, the hydrated nickel oxide-titanium dioxide materials can be employed to create a photovoltaic device for electricity generation.

Another significant patent involves a low-temperature process for forming metal suboxides on substrates through cathodic arc deposition. This method allows for precise control over the ratio of oxide to metal in the deposited coating by adjusting various parameters, such as the pressure of oxygen in the deposition chamber and the density of the metal flux. This innovative approach results in an electrically conductive metal suboxide, such as titanium, which can be applied to electrodes, enhancing their performance by reducing unwanted oxygen evolution during charging.
