研究目的
Investigating the formation of a nanoscale graphite hydrosol under the influence of terahertz laser radiation.
研究成果
The study demonstrated the reproducible formation of a nanoscale graphite hydrosol under the influence of terahertz laser radiation, with potential applications in heterogeneous catalysis, mechanochemistry, and sample preparation for elemental analysis.
研究不足
The study is limited to the use of graphite GE as the container material and distilled water for hydrosol formation. The effects of other materials or solvents were not explored.
1：Experimental Design and Method Selection
The study involved the exposure of water surface to focused terahertz radiation from the Novosibirsk free-electron laser to form a nanoscale graphite hydrosol.
2：Sample Selection and Data Sources
Low-ash electrode graphite of the commonly used brand GE with a purity of 99.5% was used as the container material. Distilled water was used for the hydrosol formation.
3：List of Experimental Equipment and Materials
Novosibirsk free electron laser (FEL),Integra scanning probe nanolaboratory (NT-MDT, Zelenograd),JEM-2010 device (JEOL, Japan) with an EDX elemental analyzer,Analytical balance,Micropipette,Ultrasonic bath
4：Experimental Procedures and Operational Workflow
A hole was made in the graphite container, filled with distilled water, and briefly exposed to focused terahertz radiation. The resulting hydrosol was then analyzed using atomic force microscopy and transmission electron microscopy.
5：Data Analysis Methods
The fractional composition of the particles was determined using an Integra scanning probe nanolaboratory. Transmission electron microscopy was performed with a JEM-2010 device. Gwyddion software was used for processing microscopic images and measuring particle sizes.
