According to the estimates of many authors, in 10-15 years, the world market for nanotechnology products will amount to about 1 trillion $. The share of nanomaterials, in this case, is very large (about 340 billion). Therefore, research on nanomaterials properties becomes one of the most important tasks of the science of nanostructured materials. In this regard, it will be essential to expand research on the influence of size and thermal stability; as two common problems for almost all types of nanomaterials. This review article will discuss the most popular topics on nanomaterials, nanostructures, their history, characteristics and classification as well as status of their scientific articles published in recent years. This study focuses on a range of topics related to the development, research and manufacturing applications of nanomaterials and nanotechnology. There are many problems and challenges that scientists are investigating on them. For example: what are the main differences between the properties of interfaces of nanomaterials (including hybrid ones) from the characteristics of ordinary bulk states? How widely can the self-assembly technique of nanoscale devices elements be developed, considering possible installation errors?

“…Herein, we report on in situ heating TEM observations of triangularly shaped Au nanoprisms with aspect ratios of ~1:3, which have considerably larger contact area (with substrates) to volume ratios in comparison with other anisotropic nanoparticles such as nanorods or nanocubes [ 15 , 16 ]. Due to their unique shape, higher surface free energy, and size-dependent physical and chemical properties, etc., Au nanoprisms have potential applications in the fields of catalysis, optics, and biomedicine [ 22 , 23 , 24 , 25 , 26 ]. Our in-situ study, apart from its complementary role to the existing phase transition and kinetics investigations of metal nanoparticles, will also aim to address two emerging questions as follows.…”

“…Therefore, we will also carry out heating TEM observations of nanoparticle aggregates to identify whether the evaporation behaviors can be altered by the sintering effect. The phase-transition mechanisms revealed by the in-situ heating TEM imaging should help to the optimized preparation of nanoparticles and nanostructures through, e.g., laser ablation [ 26 ].…”

In Situ Transmission Electron Microscopy Investigation of Melting/Evaporation Kinetics in Anisotropic Gold Nanoparticles

We report on thermal stability and phase transition behaviors of triangular Au nanoprisms through in situ heating transmission electron microscopy. With rising temperature, Au nanoprisms exhibit fluctuating surface reconstructions at the corner regions. When a quasi-melting state is reached at the temperature below bulk melting points, the evaporation is initiated commonly at a corner with low curvature and containing sharp intersection points. The subsequent annealing process leads to the gradual evaporation, which, in the absence of thick carbon coverages, is accompanied by marked shape reconstructions. The thermal stability and evaporation behaviors are not evidently regulated by nanoprism aggregations.

“…Different ablation mechanisms are implemented depending on the power of the particle flow and the pulse duration [2,4,7]. In the 1960s, the thermal model formed on the basis of data obtained when study ing the results of the impact of continuous wave lasers and lasers with millisecond pulses working in the free generation mode was one of first [2].…”

Erosion of the surface of St3 type steel and BrB2 type bronze samples as well as bronze and cop per samples with zirconium coating under the effect of compression plasma flows is studied. The results show the increase in mass removed from the surface of samples with the growth of energy absorbed by the surface layer and with the growth of the number of pulses. Probable mechanisms of erosion have been discussed. Ero sion leads to the decrease in the coating element concentration in the alloyed layer in the case of the coat ing/substrate system treatment. This effect depends on thermal characteristics of the treated material.
