成果简介	NOVELTY - Synthesizing (M1) flower-like nanostructures of zinc iron(III) oxide at pilot scale comprises: measuring and combining 0.624-0.783 kg zinc(II) nitrate hexahydrate and 0.812-0.982 kg iron(III) nitrate nonahydrate; thoroughly mixing measured quantities with 1.5-1.8 M potassium hydroxide solution to create uniformly blended slurry; and subjecting slurry to gentle heating (102) to evaporate water content to form white-colored powder. The method further comprises: transferring off-white powder into crucible made of stainless steel or silica; placing crucible inside muffle furnace; precisely setting the furnace temperature of 650-780℃; subjecting (103) powder to calcination in furnace for 8-12 hours; deactivating the muffle furnace and allowing the crucible, along with its contents, to cool to room temperature within furnace; and meticulously collecting the resulting light brown-colored perovskite material for utilization in alcohol sensitivity experiments. USE - The method is useful for synthesizing flower-like nanostructures of zinc iron(III) oxide at a pilot scale which is used to fabricate alcohol vapor sensing device (claimed). ADVANTAGE - The method: provides a highly efficient sensor capable of accurately measuring alcohol levels in the breath of drivers; enhances road safety and prevents countless accidents; employs advanced sensor technology utilizing perovskite materials, which enhances its effectiveness as a tool for detecting intoxicated drivers; and provides lightweight and compact design of the sensor which ensures portability, making it ideal for incorporation into handheld devices or other compact systems for drunk driving detection. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for fabricating (M2) an alcohol vapor sensing device, comprising utilizing a ceramic cylindrical tube with specified dimensions, applying gold paste to the tube to establish parallel electrodes, carefully inserting a cylindrical heating coil into the tube, establishing electrical contacts with the gold electrodes using platinum wire, affixing the entire assembly to a rigid plastic substrate, and ensuring optimal electrical contact through the utilization of nickel-plated bronze pins. DESCRIPTION OF DRAWING(S) - The figure illustrates schematic view for synthesizing of flower-like nanostructures of zinc iron(III) oxide for enhanced acetone sensing, and aligning seamlessly. 101Mixing zinc(II) nitrate hexahydrate, iron(III) nitrate nonahydrate, beetel-nut seed powder, and potassium hydroxide solution 102Pre-heating mixture on hot surface to remove excess water 103Conducting calcination for synthesis of nanoparticles 104Fabricating vapor sensing device 105Conducting ethanol sensitivity measurements under optimized conditions
