Lattice vibrations and Raman scattering in two-dimensional layered materials beyond graphene

Carbon nanotubes CNTs are receiving a great deal of attention as a catalyst support for different energy applications, due to their high surface area and high conductivity. Recent literature studies have shown that the application of CNTs mainly depends on their surface functionalization process. Typically, pristine CNTs as produced have no functional groups, which is usually considered as an obstacle to their widespread application. In this chapter, we highlight the different techniques used to functionalize the surface of CNTs, including physical and chemical functionalization processes. We show the advantages and the drawbacks of the different functionalization processes. Additionally, we explain in detail the different techniques used to characterize the CNTs before and after functionalization processes. Furthermore, we focus on polymer wrapping techniques of CNTs to create active nanocomposite materials for energy applications, in particular the applications in the agriculture field to fight pollution and make farming activity easier and more efficient.

Updated to include expanded coverage of the preparation, purification, structural characterization, and common application areas of single- and multi-walled CNT structures, this work compares, contrasts, and, where appropriate, unitizes CNT to graphene. New chapters encompass recent developments in the theoretical treatments of electronic and vibrational structures, and magnetic, optical, and electrical solid-state properties, providing a vital base to research. Current and potential applications of both materials, including the prospect for large-scale synthesis of graphene, biological structures, and flexible electronics, are also critically discussed. Graduate-level materials scientists and solid state physicists or chemists working with any allotrope of carbon. Kazuyoshi Tanaka received a doctorate of Engineering degree from Kyoto University in under the guidance of late Professor Kenichi Fukui who was a co-laureate of Nobel Prize in chemistry in with Professor Roald Hoffmann in Cornell University. Using the technique, he has brought a new type of information of local atomic structures of crystals into condensed matter physics, solid state chemistry, crystallography, mineralogy and materials science.

We review lattice vibrational modes in atomically thin two-dimensional 2D layered materials, focusing on 2D materials beyond graphene, such as group VI transition metal dichalcogenides, topological insulator bismuth chalcogenides, and black phosphorus. Although the composition and structure of those materials are remarkably different, they share a common and important feature, i. Black phosphorus , including crystalline structures and stacking order. We then review the studies on vibrational modes of layered materials and nanostructures probed by the powerful yet nondestructive Raman spectroscopy technique. Based on studies conducted before , recent investigations using more advanced techniques have pushed the studies of phonon modes in 2D layered materials to the atomically thin regime, down to monolayers.

Surface Functionalization of Carbon Nanotubes for Energy Applications

Raman spectroscopy has been already established as a powerful tool for characterizing the different types of carbon nanostructures , ranging from the highly ordered two-dimensional graphene and one-dimensional nanotubes , down to disordered materials, like nanographite and charcoal. Here we focus on the recent advances of Raman spectroscopy within carbon nanoscience. We discuss in situ nano-manipulation and Raman imaging for addressing controlled perturbations; multi-technique work for the development of nanometrology; crossing the diffraction limit with near-field optics for high resolution imaging.

 А-а, Росио - прелестное создание. - Мне нужно немедленно ее увидеть. - Но, сеньор, она занята с клиентом.

 - Я думал, что… - Ладно, не в этом. В главном банке данных происходит нечто странное. Джабба взглянул на часы.

 Да, панк, - сказала Росио на плохом английском и тотчас снова перешла на испанский.  - Mucha joyeria. Вся в украшениях. В одном ухе странная серьга, кажется, в виде черепа. - В Севилье есть панки и рокеры. Росио улыбнулась: - Todo bajo el sol. Чего только нет под солнцем.

 Вы правы, сэр.

 Не может быть? - повторил он, сохраняя ледяной тон.  - Может, пройдем, чтобы я смог вам это доказать. - Не стану вас затруднять, - ухмыльнулась она, - благодарю за предложение. Но все же кто. Беккер держался своей легенды: - Я из севильской полиции.

 - Танкадо отдал кольцо с умыслом. Мне все равно, думал ли он, что тучный господин побежит к телефону-автомату и позвонит нам, или просто хотел избавиться от этого кольца.

Выходит, мне придется встать. Он жестом предложил старику перешагнуть через него, но тот пришел в негодование и еле сдержался. Подавшись назад, он указал на целую очередь людей, выстроившихся в проходе. Беккер посмотрел в другую сторону и увидел, что женщина, сидевшая рядом, уже ушла и весь ряд вплоть до центрального прохода пуст.

    Carbon nanotubes CNTs possess remarkable nonlinear optical properties; a particular application is to function as a mode locker used in ultrafast fiber lasers to produce ultrashort optical pulses.
