An electrode of a chemical cell includes a substrate having a surface, an array of conductive projections supported by the substrate and extending outward from the surface of the substrate, each conductive projection of the array of conductive projections having a semiconductor composition for reduction of carbon dioxide (CO) in the chemical cell, and a catalyst arrangement disposed along each conductive projection of the array of conductive projections, the catalyst arrangement including a copper-based catalyst and an iron-based catalyst for the reduction of carbon dioxide (CO) in the chemical cell.

A method is provided for designing and fabricating a removable partial denture (RPD) framework including clasp retainers configured for removable engagement with abutment teeth of a patient. The method includes obtaining an initial digital model of the RPD framework based on patient image data. For each clasp retainer, a set of relevant geometric parameters is identified, each relevant geometric parameter being provided with a nominal value, and a target value of dislodging force is provided. The method further includes performing a force analysis on the initial digital model to determine corrected values for the relevant geometric parameters of each clasp retainer such that when the corrected values are assigned to the relevant geometric parameters, the dislodging force matches its target value. The method also includes obtaining a corrected digital model based on the corrected values, and fabricating the RPD framework based on the corrected digital model.
