Directional liquid dynamics of interfaces with

Photomechanical polymers, usually prepared by a single film of a liquid crystal network containing azobenzene, can bend directly under light (27, 62). In 2016, this photodeformable material was used as a tubular microactuator, which can change asymmetrically via light irradiation, and liquid slugs inside the deformed conical tube can transport spontaneously.

Phonograph

A phonograph, in its later forms also called a gramophone (as a trademark since 1887, as a generic name in the UK since 1910) or since the 1940s called a record player, is a device for the mechanical recording and reproduction of sound.The sound vibration waveforms are recorded as corresponding physical deviations of a spiral groove engraved, etched, incised, or impressed into the surface of a

A method for bulk separation of single-walled tubular fullerenes ( 100 ) based on helicity is provided wherein a solution or suspension of the single-walled tubular fullerenes ( 100 ) is flowed onto a crystalline or highly oriented substrate ( 30 ). The single-walled tubular

Formation of single crystalline ZnO nanotubes without catalysts

that single crystal ZnO nanotubes can be directly grown on planar substrates without using catalysts and templates. These results are guided by the theory of nucleation and the vapor-solid crystal growth mechanism, which is applicable for transforming other .

2021/4/28Carbon vapors cool down rapidly during expansion, and carbon atoms quickly condense to form tubular structures with the help of catalyst particles. MWNTs can be synthesized when pure graphite is vaporized, and SWNTs are grown from graphite-transition metal ( cobalt, nickel,

Tubular graphite cones with single

Tubular graphite cones (TGCs) with a single-crystal nanotip have been achieved by means of microwave plasma-assisted chemical vapor deposition using in-situ-evaporated Fe catalysts. The absence of the disorder-induced D band in Raman spectra revealed the

Stronger than Steel: Carbon Nanotubes

GraphiteGraphite • Graphite is a conductor, and can be used as the material in the electrodes of an electrical arc lamp, or as the lead in pencils. • Each carbon atom is covalently bonded to three other surrounding carbon atoms. •Each carbon atom possesses an sp2 orbital

Science and Technology of the Twenty

He observed that tubular graphite of nanometer scale could be produced using this thermolytic process, and imaged the first ever-observed SWNTs and MWNTs (). Unfortunately, this report ( 1 ) did not cause a great impact because researchers were more interested in micron-size carbon fibers.

Aerosol Processing of Graphene and Its Application to Oil

Graphene (GR) is a flat monolayer of sp 2-bonded single carbon atoms densely packed into a honeycomb crystal lattice 1). GR can be synthesized by various methods such as mechanical exfoliation of graphite, chemical vapor deposition from carbon based precursor, and chemical oxidation and reduction of graphite.

Graphite Polyhedral Crystals

Polyhedral nano- and microstructures with shapes of faceted needles, rods, rings, barrels, and double-tipped pyramids, which we call graphite polyhedral crystals (GPCs), have been discovered. They were found in pores of glassy carbon. They have nanotube cores and graphite faces, and they can exhibit unusual sevenfold, ninefold, or more complex axial symmetry. Although some are giant radially

They found gold nanowires having single-wall and multi-wall tubular structures (helical multi-shell magic number seven structure). Using electron holography, Hirayama et al. [10] observed two-dimensional electric potential distributions in a cross section of a Metal-Oxide-Semiconductor Field-Effect-Transistor (MOSFET) fabricated from a silicon wafer with a boron concentration of 1015cm -3 .

Penta

Carbon has many faces––from diamond and graphite to graphene, nanotube, and fullerenes. Whereas hexagons are the primary building blocks of many of these materials, except for C20 fullerene, carbon structures made exclusively of pentagons are not known. Because many of the exotic properties of carbon are associated with their unique structures, some fundamental questions arise: Is it

Yolk‐shell materials with single binary, ternary, quaternary, and quinary systems are systematically synthesized on page 2224 using scalable spray pyrolysis. This process is highly efficient, allows high throughput, comprises a single‐step reaction, and is a continuous process that yields a homogeneous composition and enables facile control of the mean size.

GRAPHENE: A NANOSCALE QUANTUM PLAYING FIELD

Graphite is still capable of creating quite a sensation within the physics commu-nity[1-4], with recent reports that single layers of graphite, called graphene, have been isolated for the first time[5,6], and unusual quantum properties were found in such systems[7-9].
