Water is a most crucial and limited resource on the Earth, which has contaminated due to the addition of heavy metals, pathogens, pesticides, and many organic and inorganic substances. Currently, the research has been focused on the sustainable remediation approach for waste reclamation. Therefore, an affordable technology of wastewater treatment could tackle the problem of water. Nanotechnology is an efficient, affordable, effective, and durable method for water treatment. Nanomaterials have several properties such as specific surface area, high reactivity, high degree of functionalization, size-dependent properties, etc., which make them appropriate materials in wastewater treatment. The present chapter comprehensively describes the characteristics of different nanomaterials and their role in the restoration of aquatic ecosystem.

- Fullerenes

Fullerenes are chemical structures made of carbon atoms. The stable form is molecule composed of 60 carbon atoms arranged in a soccer ball-shaped structure. With respect to its electron donor and acceptor capability and photochemical behavior fullerenes can be effective antioxidants and radical scavengers or prooxidants and photosensitizers. These properties of fullerenes have paid attention on their possible biological applications. Results of previous studies point to the great dependance of fullerenes activity upon quality, quantity and geometry of substituents in fullerene derivatives. Some of fullerene derivatives show antiviral and antimicrobial activity, including anti-HIV properties. C60 and its derivatives are able to exhibit cytotoxic and enzyme-inhibiting abilities as well as radical-quenching and antioxidative abilities. Generation of reactive oxygen species under influence of visible light is another ability of fullerene derivetives desired in photodynamic therapy.

The sonication-driven dispersion of multi-wall carbon nanotubes (MWCNTs) in aqueous surfactant solution has been monitored by UV–vis spectroscopy and transmission electron microscopy. Time dependent sonication experiments reveal that the maximum achievable dispersion of MWCNTs corresponds to the maximum UV–vis absorbance of the solution. With higher surfactant concentration the dispersion rate of MWCNTs increases and less total sonication energy is required to achieve maximum dispersion. Dispersion of higher MWCNT concentrations requires higher total sonication energy. For eﬀective dispersion the minimum weight ratio of surfactant to
MWCNTs is 1.5–1. The surfactant molecules are adsorbed on the surface of the MWCNTs and prevent re-aggregation of MWCNTs so that a colloidal stability of MWCNT dispersions could be maintained for several months. The maximum concentration of MWCNTs that can be homogeneously dispersed in aqueous solution is about 1.4 wt%.

The invention of carbon and its allotropes have transformed the electronic and optoelectronic industry due to their encouraging properties in a large spectrum of applications. The interesting characteristic of carbon is its ability to form many allotropes due to its valency. In recent decades, various allotropes and forms of carbon have been invented, including fullerenes, carbon nanotubes (CNTs), and graphene (GR). Since the inception of nanotechnology, carbon allotropes-based nanocomposites have become a leading sector of research and advancement due to their unique bonding properties. Fullerenes and CNTs-based polymer nanocomposites have attracted significant research interest due to their vast applications in every sphere of science and technology. Current research impetus reveals that carbon and its allotropes have revolutionized the industry and academia due to their fascinated properties. Recent advances in various aspects of graphene, CNTs, graphene nanoribbons, fullerenes, carbon encapsulates, and their nanocomposites with polymeric materials and their different applications are reported in this review article. Also, current status and future prospects of graphene-based polymer nanocomposites are presented in common along with proper citations extracted from the scientific literature. Moreover, this article is a unique collection of vital information about GR, CNTs, fullerenes, and graphene-based polymer nanocomposites in a single platform.

This research uses computational simulations using SIESTA (Spanish Initiative for Electronic Simulations with Thousands of Atoms) package based on Density Functional Theory (DFT) to explore the free energies, interaction energies, relative stability, stability of bonds and charge transfer abilities of Organic Photovoltaic (OPV) systems comprising of bis[methano- fullerene(6,6)-phenyl-C61-butyric acid methyl ester] (bisPCBM) as the acceptor and eight different donor polymers. The novel donor polymers are computationally designed based on poly[4,8-bis-substituted-benzo [1,2-b:4,5-b’]dithiophene-2,6-diyl-alt-4-
substituted-thieno[3, 4-b]thiophene-2,6-diyl] (PBDTTT) polymer, the main structural changes being the incorporation of Se and F atoms. From the results it was clear that PCBM makes a wiser choice as the donor compared to bisPCBM for computer simulations. Influence of F atoms was observed in the stability of the system both energetically and structurally. Incorporation of Se negatively affects the feasibility of acceptor-donor interaction.

In recent years, we have witnessed to fast developments in the medicinal field of hydrogels containing various forms of integrated nanostructured carbon that adds interesting mechanical, thermal , and electronic properties. Besides key advances in tissue engineering (especially for conductive tissue, such as for the brain and the heart), there has been innovation also in the area of drug delivery on-demand, with engineered hydrogels capable of repeated response to light, thermal, or electric stimuli. This mini-review focusses on the most promising developments as applied to the gelation of pro-tein/peptide (including self-assembling amino acids and low-molecular-weight gelators), polysaccha-ride, and/or synthetic polymer components in medicine. The emerging field of graphene-only hydro-gels is also briefly discussed, to give the reader a full flavor of the rising new paradigms in medicine that are made possible through the integration of nanostructured carbon (e.g., carbon nanotubes, nanohorns, nanodiamonds, fullerene, etc.). Nanocarbons are offering great opportunities to bring on a revolution in therapy that the modern medicinal chemist needs to master, to realise their full potential into powerful therapeutic solutions for the patient.

In recent decades, micro and nanoscale technologies have become cutting-edge frontiers in material science and device developments. This worldwide trend has induced further improvements in actuator production with enhanced performance. A main role has been played by nanostructured carbon-based materials, i.e., carbon nanotubes and graphene, due to their intrinsic properties and easy functionalization. Moreover, the nanoscale decoration of these materials has led to the design of doped and decorated carbon-based devices effectively used as actuators incorporating metals and metal-based structures. This review provides an overview and discussion of the overall process for producing AC actuators using nanostructured, doped, and decorated carbon materials. It highlights the differences and common aspects that make carbon materials one of the most promising resources in the field of actuators.

The review describes the use of microwave technology to carry out 1,3-dipolar cycloaddition reactions, an important tool for the construction of five-membered heterocycles. Microwave methodology can be applied to generate 1,3-dipoles (nitrones, nitrile oxides, azomethine ylides, azomethineimines, nitrile imines, azides, carbonyl ylides) and to promote the subsequent cycloaddition and usually avoids harsh reaction conditions. This nonconventional energy source is able to reduce chemical reaction times and to increase yields and in some cases can lead to different outcomes from those obtained with conventional heating. The review highlights the more recent developments in the area with particular emphasis on aspects related to efficiency and to regio- and stereoselectivity. (© Wiley-VCH Verlag GmbH & Co.

The development of science, technology and technique offer ample opportunities to solve problems associated with various complications in oil production technology. The innovative technologies should include nanotechnological approaches based on the effect of "low concentrations and perturbations". Currently, nanotechnology capabilities are widely used in individual technological operations at the fields of Azerbaijan using this effect. In contrast to the traditional approaches, the authors of the paper carried out a series of experimental studies on the effects of fullerene, graphene and taunit on the properties of cement stone be used for cementing of the near bottom hole zone of the productive reservoir. The developed nanotechnology is successfully introduced in the offshore fields of Azerbaijan.
