In the present study, exfoliated graphite generated from a high-pure graphite precursor through a cost-effective and environmentally friendly planetary ball milling technique has been evaluated for its supercapacitive and microwave absorption properties. The exfoliated graphite exhibits a two-fold increase in surface area compared to the high-pure graphite. The O/C ratio increased to 16.69% due to the presence of oxygen groups after ball milling, enhancing the microwave absorption and electrochemical energy storage performance of exfoliated graphite. Remarkably, the exfoliated graphite shows an enhanced microwave absorption of ∼59.15% across 8.2-12.4 GHz. Further for the realisation of the practical application, simulation study has been incorporated showing a minimum reflection loss of -25.53 dB at 9.7 GHz combining with a ferrite material. It also exhibits an excellent specific capacitance value of 177 Fg^-1 at a current density of 0.5 Ag^-1 for three electrode system. When assembled as a symmetric two-electrode system the exfoliated graphite exhibits an energy density of 1.66 Whkg^-1 with a power density of 420 Wkg^-1.

A thermophysical calculation based on an analytical solution of the heat conduction equation for a homogeneous sphere and infinite medium possess different thermal properties, allowed analyzing the dynamics of a carbon microparticle cooling in the degenerate optical microcavitation modes (long-lived microbubbles) and tracing the trend of changes in the accumulated temperature depending on laser parameters. A region of parameters (pulse number, repetition rate) in which the transition from the fragmentation to defragmentation of the agglomerates occurs has been experimentally found. Differentiation of these processes contributed to the definition of the role of degenerate optical microcavitation in combination with accumulative effects and the detailing of their mechanisms. A fragmentation mechanism has been established that takes into account degenerate optical microcavitation. A mechanism for defragmentation of carbon black nanoparticle agglomerates has been proposed based on the creation of prerequisites for water transition into the state of a supercritical fluid accompanied by partial agglomerate dissolution in laser-induced long-lived microbubbles at the cooling stage and on the decrease of agglomerate maximum heating temperature because of increased light scattering by long-lived microbubbles.

While SWCNTs can be synthesized with lengths up to several micrometers, opened SWCNTs typically show maximum lengths of only a few hundred nanometers, limiting their use for filling with long, one-dimensional arrays of molecules or studying the transport of molecules through their hollow core. Here, we present a mild opening procedure to achieve open, yet long SWCNTs. By comparing different processing steps in their ability to open SWCNTs without significantly reducing the SWCNT length, we present a simple three-step procedure including an air oxidation, a mild acidic treatment, and a high-temperature vacuum annealing, resulting in nearly complete opening of all SWCNTs in a sample, independent of the SWCNT chiral structure and diameter. The procedure has been applied to different SWCNT starting batches to confirm its general applicability. While the opening of SWCNTs is characterized by optical spectroscopy after water filling, statistical SWCNT length distributions are obtained through atomic force microscopy and hyperspectral photoluminescence imaging of SWCNTs.
