Abstract

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.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS The present application is a continuation of U.S. application Ser. No. 17/690,767, filed Mar. 9, 2022, which claims the benefit of U.S. Provisional Application No. 63/158,645, filed Mar. 9, 2021, entitled “Combinatorial Synthesis and High Throughput Screening of Multielement Nanoparticles and Functional Bulk Materials,” each of which is incorporated by reference herein in its entirety. FIELD The present disclosure relates generally to multielement material synthesis, and more particularly, to systems and methods for determination of a composition of multielement material (e.g., nanocluster, nanoparticle, or bulk material) for a particular application via combinatorial synthesis and screening. BACKGROUND Nanoparticles with a range of sizes and morphologies have been studied for various catalytic applications. These nanoparticles are typically comprised of no more than three elements to avoid synthetic complexity and structural heterogeneity. Multielement nanoclusters having three or more elements thus present a vast and largely undiscovered chemical space that can offer synergistic interactions between different elements. Yet, with increasing compositional complexity, conventional fabrication methods can lead to multielement particles with large size distributions and/or inhomogeneous structures (e.g., phase separation and/or elemental segregation within the particles), which may result from the inability of conventional fabrication methods to control the kinetics and dynamics of chemical reactions at the nanoscale among dissimilar constituent elements. As a result, it remains a challenge to tune the composition of fabricated materials in order to systematically study the properties thereof, thus limiting material discovery, property optimization, and mechanistic understanding for different functionalities. Embodiments of the disclosed subject matter may address one or more of the above-noted problems and disadvantages, among other things. SUMMARY Embodiments of the disclosed subject matter system provide systems and methods for combinatorial synthesis and screening of multielement materials, for example, multielement nanoclusters, nanoparticles, or bulk materials. Multielement nanomaterials hold great promise for various applications due to their widely tunable surface chemistries. Yet it remains challenging to efficiently study this multi-dimensional space because conventional approaches are typically slow and depend on serendipity. Embodiments of the disclosed subject matter can thus address these deficiencies by offering a high-throughput technique for combinatorial compositional design (e.g., formulation in solution phases) and rapid synthesis (e.g., rapid, high-temperature exposure on the order of seconds) of multielement (e.g., multimetallic) materials (e.g., nanoparticles, nanoclusters, and/or bulk materials) with a homogeneous structure. The materials with different compositions can be subject to rapid screening, for example, to discover optimal and/or synergistic compositions for particular applications, such as but not limited to use as a catalyst, a plasmonic nanoparticle, an energy storage device, an optoelectronic device, a solid-state electrolyte, an ion conductive membrane, a fluorescent material, a component thereof, or any combination of the foregoing. In one or more embodiments, a method can comprise depositing one or more first precursors on a first portion of a substrate and depositing one or more second precursors on a second portion of the substrate. The second portion can be spaced from the first portion. The method can further comprise subjecting each of the first and second portions of the substrate to a first temperature for a first time period so as to convert the deposited one or more first precursors into a first material and to convert the deposited one or more second precursors into a second material. The first material can have a different composition than the second material. The first temperature can be greater than or equal to about 500° C., and a duration of the first time period can be less than about 60 seconds. In some embodiments, the method can further comprise testing each of the first and second materials with respect to an electrical property, a chemical property, an optical property, or any combination thereof. In some embodiments, the method can also comprise determining a composition of a material for use in a predetermined application based at least in part on results of the testing. In one or more embodiments, a system can comprise a dispensing device, a heating device, and a control system. The dispensing device can have a nozzle facing a surface of a substrate and constructed to deposit precursors onto the substrate. At least one of the nozzle and the substrate can be movable with respect to the other. The heating device can be constructed to generate a first temperature of at least 500° C. The control system can be o
