“…For instance, atomic force microscopy (AFM) was utilized to reveal the force–distance curve of nanotubes while buckling [ 87 ]. More direct characterizations of nanotube buckling were obtained by in situ transmission electron microscopy (TEM) [ 88 , 89 , 90 ], as partly demonstrated in Figure 2 (see Section 4.2 ). However, the experimental investigation of nanotube buckling remains a challenge because of difficulties in manipulation at the nanometric scale.…”

“…We now turn to experimental facts [ 128 ]. Because of the difficulty in sample preparation and manipulation, only a few attempts have been made to perform axial buckling measurements [ 88 , 89 , 90 ]. In particular, experimental realization of shell buckling under compression has largely behind, though its signature has been obtained via nanoindentation [ 129 ].…”

The nonlinear mechanical response of carbon nanotubes, referred to as their “buckling" behavior, is a major topic in the nanotube research community. Buckling means a deformation process in which a large strain beyond a threshold causes an abrupt change in the strain energy vs. deformation profile. Thus far, much effort has been devoted to analysis of the buckling of nanotubes under various loading conditions: compression, bending, torsion, and their certain combinations. Such extensive studies have been motivated by (i) the structural resilience of nanotubes against buckling and (ii) the substantial influence of buckling on their physical properties. In this contribution, I review the dramatic progress in nanotube buckling research during the past few years.

“…By now, there are several methods to investigate the instability properties of CNTs when subjected to an axial force. The instability phenomenon of CNTs under compressive loading was observed experimentally by TEM [59][60][61][62]. Figure 14 shows the direct observation of nanotube buckling characterization by in situ transmission TEM.…”

This paper reviews the recent research of carbon nanotubes (CNTs) used as nanomechanical sensing elements based mainly on theoretical models. CNTs have demonstrated considerable potential as nanomechanical mass sensor and atomic force microscope (AFM) tips. The mechanical and vibrational characteristics of CNTs are introduced to the readers. The effects of main parameters of CNTs, such as dimensions, layer number, and boundary conditions on the performance characteristics are investigated and discussed. It is hoped that this review provides knowledge on the application of CNTs as nanomechanical sensors and computational methods for predicting their properties. Their theoretical studies based on the mechanical properties such as buckling strength and vibration frequency would give a useful reference for designing CNTs as nanomechanical mass sensor and AFM probes.

“…Schematic of the annular cylindrical region surrounding the ion path, has such temperature and pressure conditions that favour transition from fullerene to its dimmer or polymer in terms of the lattice distortions 63 whereas the bulk Ni is known to be not affected by SHI irradiation. 64 , a very useful aspect in practical applications. Favorable changes in transition temperature have been observed in the irradiated LCMO, which are likely due to the pressure exerted by the material in the ion track to its surrounding 65 .…”

Swift heavy ions (SHI) available with 15 million Volt Pelletron accelerator at Inter University Accelerator Centre (IUAC) Delhi, formerly known as Nuclear Science Centre, (NSC), provide a unique opportunity to researchers for accelerator based materials science research. The major research areas can be broadly categorised as electronic sputtering, interface modifications, synthesis and modification of nanostructures, phase transitions and ion beam-induced epitaxial crystallisation. In, general, SHI irradiation based-materials may not be economically feasible, still it could be of interest for very specific cases in defence and space research. The paper gives a glimpse of the current research activities in materials science with SHIs, at IUAC.Keywords: Swift heavy ions, SHI, materials science, materials research systhesis of materials, characterisation of materials, nuclear energy loss, ion energy loss, electronic energy-loss-defects in materials, defect engineering INTRODUCTIONThe ions with energy ranging from a fraction of keV to GeV are useful in synthesis, modification and characterization of materials. The energetic ions during their passage through a material loose energy via two processes. These are nuclear energy loss S n and electronic energy loss S e . In the former process, the energy is lost by elastic collisions of incident ions with the atoms in the material, which is dominant at low energies. In the electronic energy loss process, dominant at high energies (>1 MeV/nucleon), the energy is lost by inelastic collisions of the ion with the atoms, leading to excitation or ionisation of the atoms. At these energies of heavy ions, the velocity of the ion is comparable to or higher than the velocity of Bohr electron. The ions with such high energies are also referred to as Swift Heavy Ions (SHI). The electronic energy loss for SHI is, generally, about two orders of magnitude higher than the nuclear energy loss1 . An interesting characteristic of the SHI is that it creates a columnar type of defect along its path (called as ion track), specially, in insulators. SHI during its passage through material can cause defect annealing, cluster of point defects and columnar type of defects depending on the mass and energy of the ion and the material. Therefore the SHI can be used for engineering the defects in the materials. The parameters of ion beam, which play crucial role in defect engineering, are the energy deposited per unit length and the fluence.The ion mass and its energy, decide the magnitudes of the electronic as well as nuclear energy losses. Especially for heavy ions at high energies (i.e., for SHI), the electronic energy loss decides the type of defects as the nuclear energy loss. The other ion beam parameter, fluence, dictates the number of defects (produced). The number of ion
