Carbon nanomaterials and compositions containing them are attracting increased attention. The high variety of carbon nanomaterials structures and morphologies as well as the simplicity of its surface functionalization, make it possible to effectively select the nanomaterial properties for the target task. The presented study provides an overview of the oil industry stages and shows the main directions of using nanotechnology in them. The main attention is focused on the trends of carbon nanomaterials (nanodiamonds, carbon nanotubes and graphene-like materials) applications in the petroleum extraction stage (drilling and enhanced oil recovery processes).

AbstractCarbon nanomaterials have unique physicochemical properties based solely on their small size, which makes them ideal for nano-oncology. While there have been tremendous advances in the current treatment of high-risk cancers, conventional treatment still causes harm to the surrounding healthy tissue. Carbon nanomaterials such as carbon nanotubes, carbon nanohorns, and graphenes have been increasingly used in the field of cancer photothermal therapy. Through surface functionalization, carbon nanomaterials can be specifically targeted to the tumorous tissue allowing for an increase in therapeutic potential. The unique photo-electron transfer features of carbon nanomaterials coupled with functional moieties, is proving useful for their use in the photothermolysis of cancer cells.

Foam In Porous Media

Abstract A laboratory study was made of the variables which affect the generation, propagation, quality und nature of foam produced inside a porous medium. It is shown that foam can be generated and propagated in porous media representative of reservoir rocks at pressure levels ranging from atmospheric to 1,000 psig, and under pressure differentials ranging from 1.0 to 50 psi/ft. The quality of foam depends on the type of foaming agent, the concentration of foaming solution, the physical properties of the porous medium, the pressure level, and the composition and saturation of fluids present. The nature of foam depends upon the type of foaming agent and its concentration in the foaming solution. The study shows that the flow behavior of foam in a porous medium is a complex one which cannot he correctly described in terms of the high apparent viscosity of foam. Also, the concept of relative permeability is not applicable to the flow of foam due to the associative nature of its components. On the basis of the discussed characteristics of foam, several applications of foam are suggested in oil recovery processes.

The scalable production of homogenous, uniform carbon nanomaterials represents a key synthetic challenge for contemporary organic synthesis as nearly all current fabrication methods provide heterogenous mixtures of various carbonized products. For carbon nanotubes (CNTs) in particular, the inability to access structures with specific diameters or chiralities severely limits their potential applications. Here, we present a general approach to access solid-state CNT mimic structures via the self-assembly of fluorinated nanohoops, which can be synthesized in a scalable, size-selective fashion. X-ray crystallography reveals that these CNT mimics exhibit uniform channel diameters that are precisely defined by the diameter of their nanohoop constituents, which self-assemble in a tubular fashion via a combination of arene-pefluoroarene and C—H---F interactions. The nanotube-like assembly of these systems results in capabilities such as linear guest alignment and permanently accessible channels, both of which are observed in CNTs but not in the analogous all-hydrocarbon nanohoop systems. Calculations suggest that the organofluorine interactions observed in the crystal structure are indeed critical in the self-assembly and robustness of the CNT mimic systems. This work establishes the self-assembly of carbon nanohoops via weak interactions as an attractive means to generate solid-state materials that mimic carbon nanotubes, importantly with the unparalleled tunability enabled by organic synthesis. <br>

A large number of methodologies for fabrication of 1D carbon nanomaterials have been developed in the past few years and are extensively described in the literature. However, for many applications, and in particular in catalysis, a translation of the materials to a macro-structured form is often required towards their use in practical operation conditions. This review intends to describe the available methods currently used for fabrication of such macro-structures, either already applied or with potential for application in the fabrication of macro-structured catalysts containing 1D carbon nanomaterials. A review of the processing methods used in the fabrication of macrostructures containing 1D sp2 hybridized carbon nanomaterials is presented. The carbon nanomaterials here discussed include single- and multi-walled carbon nanotubes, and several types of carbon nanofibers (fishbone, platelet, stacked cup, etc.). As the processing methods used in the fabrication of the macrostructures are generally very similar for any of the carbon nanotubes or nanofibers due to their similar chemical nature (constituted by stacked ordered graphene planes), the review aggregates all under the carbon nanofiber (CNF) moniker. The review is divided into methods where the CNFs are synthesized already in the form of a macrostructure (in situ methods) or where the CNFs are previously synthesized and then further processed into the desired macrostructures (ex situ methods). We highlight in particular the advantages of each approach, including a (non-exhaustive) description of methods commonly described for in situ and ex situ preparation of the catalytic macro-structures. The review proposes methods useful in the preparation of catalytic structures, and thus a number of techniques are left out which are used in the fabrication of CNF-containing structures with no exposure of the carbon materials to reactants due to, for example, complete coverage of the CNF. During the description of the methodologies, several different macrostructures are described. A brief overview of the potential applications of such structures in catalysis is also offered herein, together with a short description of the catalytic potential of CNFs in general.
