“…We observed that the average hydrodynamic diameter -a complex function that describes a Gaussian distribution -is centred at ca. 780 nm, in good agreement with the electron microscopy observations and the classification proposed by Serp et al 5 In order to determine the surface texture of the spheres, N 2 adsorption-desorption isotherms were measured. The CS showed a BET surface area value of 16.2 m 2 g À1 , indicative of the absence of mesoporosity on its surface, in accordance with previously published studies.…”

“…This value is intermediate between those measured for a carbon fiber (d 002 = 0.342) and activated carbon atoms (d 002 = 0.363), which is indicative of a relatively well-organised carbon structure. 5 Raman spectra have been recorded to disclose the graphitic ordering of CS. Fig.…”

“…1D). According to Serp et al classification of carbon nanoforms based on the maximum of the gasification rate, 5 our sample is located in the range of carbon nano-spheres with a combustion temperature of ca. 630 1C depicted in the DTA (see SI 4, ESI †).…”

“…4 Carbon spheres can be classified according to different parameters, like their size, nanometric texture or internal structure. [5][6][7][8] Recently, Deshmukh et al reviewed different techniques employed for the synthesis of CS, pointing out chemical vapour deposition (CVD) as one of the most versatile synthetic approaches. 9 These carbonaceous forms show a wide range of potential applications due to their thermal stability, electronic properties, high surface area or low density.…”

The gram-scale synthesis of carbon spheres with a diameter of ca. 740 nm has been achieved by means of a chemical vapour deposition method using NiFe-layered double hydroxides as a solid catalytic precursor. The presence of the catalyst (FeNi 3 ) allows controlling the final size distribution, resulting in a monodisperse sample. Their structural properties exhibited a high degree of graphitization according to their I D /I G ratio. In addition, their morphological features were unveiled by FIB-SEM and HRTEM, showing that they are formed by solid inner cores, and presenting labile chain-like structures due to accretion procedures. The solution and posterior sonication of the samples in toluene gave rise to the well-defined isolated spheres. The textural and electrochemical properties of the spheres have been tested showing non-mesoporous structures with a good behaviour as electrode materials for supercapacitors due to the presence of redox functionalities on their surface. Finally, magneto-transport measurements have been carried out, demonstrating semiconductor behaviour, as well as a positive magnetoresistance effect (ca. 72%) for the lowest studied temperature (2 K).

“…Various approaches have been used to prepare carbon spheres, such as chemical vapor deposition [11,12], the templating method [13,14], pyrolysis of carbon sources [15,16], and hydrothermal treatment [17]. Among the aforementioned approaches, the hydrothermal treatment method is more favorable because of mild operational conditions [18] and the controllable size of carbon spheres [19,20].…”

Carbon spheres have attracted a great deal of attention due to their applications as super capacitors, catalyst supports, and adsorbents. Carbon spheres can be prepared with controlled size and with oxygenated functional groups on the surface by the hydrothermal carbonization. The further processed products have a high surface area and high thermal stability. Among various methods for fabrication of carbon spheres, the hydrothermal carbonization is favored because of its mild operating conditions. In addition, hydrothermal carbonization can synthesize micro or nano scale carbon spheres environmentally friendly without employing organic solvents, surfactants, or catalysts. In this review, we present the effects of process parameters, structural characteristics of carbon spheres, possible formation mechanisms of carbon spheres, and applications in catalysis.

Nanomaterials are anticipated to revolutionize disease detection and treatment leading to the realization of a potential world market of medical nanotechnology estimated to be > $3 billion within the next 5 years. This article provides an up to date summary of the current research investigations on Nanomaterials for medical applications. Nanomaterials have been categorized based on their shape, and within each shape they have been further categorized based on their chemical composition. Similarly, the medical applications have been categorized into four main sections:medical diagnosis, medical treatment, medical devices, and tissue engineering. Prior to the discussion of medical applications, approaches to biofunctionalization of nanomaterials are also presented as it is very important that the nanomaterials are compatible in biological environment for their application in medicine.
