Ultrasonic Dispersionf Ntawm Nanomaterials
Cov cuab yeej siv ultrasonic tau siv raws li cov hauv paus ntsiab lus hauv daim duab 1. Lub piezoelectric ultrasonic transducer hloov cov hluav taws xob hluav taws xob sinusoidal rau hauv cov tshuab hluav taws xob longitudinal resonance vibration, qhov chaw resonance zaus ntawm cov cuab yeej yog 20 kHz.

Ultrasonic Dispersionf ntawm nanomaterials
Kev sib cuam tshuam ntawm lub siab tsis (ultrasound) nrog cov kua nruab nrab ua rau tsim cov kab noj hniav hauv cov kua. Cov kab noj hniav no tau txais kev sib txuas tas mus li thiab tsis tshua muaj tshwm sim thaum lawv cuam tshuam nrog lub voj voog zoo thiab tsis zoo. Qhov no mus txog rau thaum cov kab noj hniav mus txog lub vojvoog tseem ceeb, uas yog txiav txim los ntawm qhov zaus ntawm ultrasound. Lub implosion ntawm npuas tsim ib lub zos kub ntawm 5000K thiab pressures siab li 1000atm.
Nqe lus piav qhia:
Ultrasound yog ib txoj kev ua tau zoo heev nyob rau hauv tiam thiab siv cov ntaub ntawv nano loj. Feem ntau, ultrasonic cavitation hauv cov kua yuav ua rau sai thiab ua tiav degassing: pib ntau yam tshuaj lom neeg los ntawm kev tsim cov tshuaj dawb ions (radicals); ua kom cov tshuaj tiv thaiv kab mob los ntawm kev yooj yim rau kev sib xyaw ntawm cov tshuaj reactants; txhim kho polymerization thiab depolymerization
kev cuam tshuam los ntawm kev sib cais ib ntus lossis los ntawm kev rhuav tshem cov tshuaj lom neeg ruaj khov hauv cov saw hlau polymeric; nce emulsification tus nqi; txhim kho tus nqi diffusion; ua kom muaj zog emulsions los yog cov khoom tawg yooj yim ntawm micron-loj lossis nano-size cov ntaub ntawv; pab tshem tawm cov tshuaj xws li enzymes ntawm tsiaj, nroj tsuag, poov xab, los yog kab mob hlwb; tshem tawm cov kab mob los ntawm cov ntaub so ntswg; thiab thaum kawg, erode thiab rhuav tshem cov kab mob uas cuam tshuam, nrog rau cov kab mob microorganisms. Ultrasound tuaj yeem kuaj hauv chav kuaj thiab lub rooj zaum saum toj kawg nkaus ua ntej cov txiaj ntsig tau ntsuas mus txog qib kev lag luam.

Daim ntawv thov:
Cov ntawv thov ntawm Sonochemistry•Sonochemistry tau siv rau kev sib xyaw ntawm cov khoom sib xyaw rau cov ntawv thov siv hluav taws xob xws li:
1. Ultrasound assisted synthesis tau siv rau kev npaj ntawm platinum-ruthenium nanoparticles, kub thiab platinum nanoparticles thiab lwm yam rau roj cell electrodes.
2. Synthesis ntawm Cu2O-Graphene, graphene oxide-Fe2O3 rau lithium ion roj teeb electrodes.
3. Primary/Binary/Ternary nanocomposites uas muab qhov zoo tshwj xeeb capacitance, lub zog ceev, lub zog ceev thiab cyclic stability muaj feem xyuam rau cov khoom siv electrode hauv Supercapacitors. Nanocomposites ntawm cov ntaub ntawv carbon (CNT, graphene, thiab lwm yam), ua cov polymer thiab hlau oxides vim Synergistic nyhuv muaj kev txhim kho hluav taws xob.
Qhov zoo ntawm Sonochemistry • Ultrasound pab synthesis pab nyob rau hauv kev npaj ntawm uniformly faib thiab uniformly loj nanocomposites nyob rau hauv lub sij hawm luv luv thiab siv tsawg zog piv rau txoj kev xws li mechanical attrition, electrodeposition thiab lwm yam. .•Enhanced zog tau pom nyob rau hauv lub teb ntawm kinetics, selectivity, extraction, dissolution, pom, crystallinity.•Tam sim no lub siab tshaj plaws tshwj xeeb capacitance mus txog los ntawm lub supercapacitor electrode cov ntaub ntawv uas raws li npaj siv sonochemical txoj kev yog ≈1000-1200 F /g qhov twg rau txoj kev hydrothermal tau pom tias yog ≈80-100 F / g thiab qhov ntawd rau solvothermal yog ≈200F / g.
