“…npg values varied in the range [10.8 (raw CNFs)-8.6] being lower when higher the activation degree was. Anyway, npg values were pretty high if compared with those reported for conventional activated carbon or activated carbon fibers, indicating that the graphitic nature of the raw CNFs remains present in the activated samples [7].…”

The influence of different activation conditions, including activating agent/CNFs ratio, activation temperature, and He flow rate, on the pore structure development of herringbone carbon nanofibers (CNFs) was studied. The best results of activated CNFs with larger specific surface area can be achieved using the following optimized factors: RbOH/CNFs ratio = 4/1, activation temperature = 900• C ,and a He flow rate = 850 ml/min. The optimization of these three factors leads to high CNFs micropore volume, being the surface area increased by a factor of 3 compared to the raw CNFs. It is important to note that only the creation of micropores (ultramicropores principally) took place, and mesopores were not generated if compared with raw CNFs.

“…), a very limited number of studies found in the literature discuss the activation of CNFs by hydroxides [7]. Moreover, it is also very important to investigate the influence of different activation conditions on the final porous texture of these materials [8].…”

“…The heat treatment consisted of a heating ramp from ambient temperature to the final heat treatment temperature (850°C) at a heating rate of 5°C/min, followed by a 3 h plateau. Then the system was cooling back to the initial temperature [4,10,11]. He was selected as inert gas with a flow rate of 500 ml/min.…”

“…There are mainly three types of carbon nanofibers: the herringbone, in which the graphene layers are stacked obliquely with respect to the fiber axis; the platelet, in which the graphene layers are perpendicular to the fiber axis; and the ribbon, in which the graphene layers are parallel to the growth axis [4,5]. The morphology of CNFs depends on the temperature and C 2 H 4 /H 2 ratio used during the synthesis process and the catalytic metals and supports [6][7][8].…”

“…Comparing carbon nanotubes and nanofibers, the latter present a nanostructure made of graphite layers stacking which is more favorable for activation and adsorption phenomena [4]. In this regard, the specific surface area and porosity of carbons can be significantly modified by an activation process that removes the most reactive carbon atoms from the structure, increasing the surface area and porosity.…”

Cancer represents one of the main causes of human death in developed countries. Most current therapies, unfortunately, carry a number of side effects, such as toxicity and damage to healthy cells, as well as the risk of resistance and recurrence. Therefore, cancer research is trying to develop therapeutic procedures with minimal negative consequences. The use of nanomaterial-based systems appears to be one of them. In recent years, great progress has been made in the field using nanomaterials with high potential in biomedical applications. Carbon nanomaterials, thanks to their unique physicochemical properties, are gaining more and more popularity in cancer therapy. They are valued especially for their ability to deliver drugs or small therapeutic molecules to these cells. Through surface functionalization, they can specifically target tumor tissues, increasing the therapeutic potential and significantly reducing the adverse effects of therapy. Their potential future use could, therefore, be as vehicles for drug delivery. This review presents the latest findings of research studies using carbon nanomaterials in the treatment of various types of cancer. To carry out this study, different databases such as Web of Science, PubMed, MEDLINE and Google Scholar were employed. The findings of research studies chosen from more than 2000 viewed scientific publications from the last 15 years were compared.
