“…In addition to amorphous-free CNT production from ethanol, it can produce vertically aligned SWCNT when acetylene was supplied intermittently [27,28]. Ultralong CNTs were produced with ethylene precursor using water and hydrogen [29]. By employing an appropriate choice of the carbon precursor and optimal feed rate of water highquality CNTs can be produced in good yields [30,31].…”

New synergic behavior is always inspiring scientists toward the formation of nanocomposites aiming at getting advanced materials with superior performance and/or novel properties. Carbon nanotubes (CNT), graphene, fullerene, and graphite as carbon-based are great fillers for polymeric materials. The presence of these materials in the polymeric matrix would render it several characteristics, such as electrical and thermal conductivity, magnetic, mechanical, and as sensor materials for pressure and other environmental changes. This review presents the most recent works in the use of CNT, graphene, fullerene, and graphite as filler in different polymeric matrixes. The primary emphasis of this review is on CNT preparation and its composites formation, while others carbon-based nano-fillers are also introduced. The methods of making polymer nanocomposites using these fillers and their impact on the properties obtained are also presented and discussed.

“…Previous papers where intensely focused on the yield of the oil, char, and gas, of different feedstocks, by varying maximum heat, heating ramp, and therewith residual times as well as moisture content [27,43,44] and the oil quality was improved with pre-treatment [45] or via upgrading [46][47][48]. Overall, the yield of bio oil, char, and gas can be calculated as follows [49]:…”

In the last few centuries the worldwide energy demand rose to a stage were traditional power-supply networks struggle to satisfy the necessary supply of energy. Consequently, humanity is still largely dependent on every energy source possible and primarily environmentally unfriendly sources such as coal, fossil-oils, nuclear etc. Governments worldwide finally realised that those recourses are limited and began to subsides renewable energy solutions such as solar and wind energy, but by neglecting the fact that those sources have problems to supply energy 24/7 to the customers. Pyrolysis from bio feedstock is one of the technologies which can not only produce oil and gas for generators as well as fertiliser, but also conquer another problem arising from modern society, garbage reduction. Pyrolysis does exist for many years now, but

“…WA-CVD was called ‘super-growth CVD’ due to the improved CNTs synthesis [58,59]. Ren et al [60] synthesized SWCNTs by using Co-MCM-41 as a catalyst in water/ethanol-assisted CVD. They found that by increasing the H 2 O/C 2 H 5 OH ratio, the SWCNTs’ diameter increased.…”

Introduction It is 23 years since carbon allotrope known as carbon nanotubes (CNT) was discovered by Iijima, who described them as “rolled graphite sheets inserted into each other”. Since then, CNTs have been studied in nanoelectronic devices. However, CNTs also possess the versatility to act as drug- and gene-delivery vehicles. Areas covered This review covers the synthesis, purification and functionalization of CNTs. Arc discharge, laser ablation and chemical vapor deposition are the principle synthesis methods. Non-covalent functionalization relies on attachment of biomolecules by coating the CNT with surfactants, synthetic polymers and biopolymers. Covalent functionalization often involves the initial introduction of carboxylic acids or amine groups, diazonium addition, 1,3-dipolar cycloaddition or reductive alkylation. The aim is to produce functional groups to attach the active cargo. Expert opinion In this review, the feasibility of CNT being used as a drug-delivery vehicle is explored. The molecular composition of CNT is extremely hydrophobic and highly aggregation-prone. Therefore, most of the efforts towards drug delivery has centered on chemical functionalization, which is usually divided in two categories; non-covalent and covalent. The biomedical applications of CNT are growing apace, and new drug-delivery technologies play a major role in these efforts.
