Precursors for forming a plurality of multielement materials of different compositions can be deposited on different portions of a common substrate according to a combinatorial approach. The substrate can be subjected to a thermal shock, thereby converting the deposited precursors into separate multielement materials on the substrate. The thermal shock can be a temperature greater than or equal to 500° C. and a duration less than 60 seconds. In some embodiments, each multielement material can be tested with respect to an electrical property, a chemical property, or an optical property. Based on the results of the testing, a composition of a multielement material can be determined for use in a predetermined application, such as use as a catalyst, a plasmonic nanoparticle, an energy storage device, an optoelectronic device, a solid-state electrolyte, or an ion conductive membrane.

A peptide synthesis instrument can be used for small scale peptide synthesis. The instrument can include several unique features, including a compression style reaction vessel permitting quick setup of the reaction vessel, a double reaction vessel system permitting efficient mixing without loss of solvent or solvent-to-resin contact, gravity-fed heated reservoirs establishing a fixed volume for delivery to the reaction vessel, fume-free solvent addition permitting solvent addition to fixed bottles, and an improved amino acid manifold assembly which reduces the number of components and increases the ease of use of the instrument. Each of these features improve upon the current state of the art in solid phase automated peptide synthesizers.
