practical application

ewm research has suggested possible applications in excitation of optical masers, high intensity light sources communications, spacecraft propulsion, joining difficult materials such quartz, , generation of high power radio-frequency pulses. promising applications of ewm detonator, light source, , production of nanoparticles.

detonator

ewm has found use detonator, named exploding-bridgewire detonator, nuclear bombs. bridgewire detonators advantageous on chemical fuses explosion consistent , occurs few microseconds after current applied, variation of few tens of nanoseconds detonator detonator.

light source

ewm effective mechanism short duration high intensity light source. peak intensity copper wire, example, 9.6*10 candle power/cm. j.a. anderson wrote in initial spectrography studies light comparable black body @ 20,000k. advantage of flash produced in way is reproducible little variation in intensity. linear nature of wire allows shaped , angled light flashes , different types of wires can used produce different colors of light. light source can used in interferometry, flash photolysis, quantitative spectroscopy, , high-speed photography.

production of nanoparticles

nanoparticles created ewm when ambient gas of system cools produced vaporous metal. ewm can used cheaply , efficiently produce nanoparticles @ rate of 50-300 grams per hour , @ purity of above 99%. process requires relatively low energy consumption little energy lost in electric thermal energy conversion. environmental effects minimal due process taking place in closed system. particles can small 10 nm commonly below 100 nm in diameter. physical attributes of nanopowder can altered depending on parameters of explosion. example, voltage of capacitor raised, particle diameter decreases. also, pressure of gas environment can change dispersiveness of nanoparticles. through such manipulations can alter functionality of nanopowder.

when ewm performed in standard atmosphere containing oxygen, metal oxides formed. pure metal nanoparticles can produced ewm in inert environment, argon gas or distilled water. pure metal nanopowders must kept in inert environment because ignite when exposed oxygen in air. often, metal vapor contained operating mechanism within steel box or similar container.

nanoparticles relatively new material used in medicine, manufacturing, environmental cleanup , circuitry. metal oxide , pure metal nanoparticles used in catalysis, sensors, oxygen antioxident, self repairing metal, ceramics, uv ray protection, odor proofing, improved batteries, printable circuits, optoelectronic materials, , environmental remediation. demand metal nanoparticles, , therefore production methods, has increased interest in nanotechnology continues rise. despite overwhelming simplicity , efficiency, difficult modify experimental apparatus used on industrial scale. such, ewm has not seen widespread utilization in material production industry due issues in manufacturing quantity.
