Translating the unique characteristics of individual single-walled carbon nanotubes into macroscopic materials such as fibres and sheets has been hindered by ineffective assembly. Fluid-phase assembly is particularly attractive, but the ability to dissolve nanotubes in solvents has eluded researchers for over a decade. Here, we show that single-walled nanotubes form true thermodynamic solutions...

Nature has always been a productive source of new drugs. With the advent of high-throughput screening, it has now become possible to rapidly screen large sample collections. In addition to seeking greater diversity from natural product sources (micro-organisms, plants, etc.), fractionation of the crude extracts prior to screening is becoming a more important part of our efforts. As sample prepa...

OBJECTIVE The association of chlorhexidine (CHX) and sodium hypochlorite (NaOCl) to enhance their chemical properties during root canal biomechanical preparation can lead to a brown flocculate being formed. Therefore, this study evaluated the metals present in their association by atomic absorption spectrophotometry, and evaluated a possible reagent that could dissolve the flocculate, allowing ...

A video stream consists of a number of shots each of which has the boundary property, such as cut, fade, dissolve, wipe, etc. The shot boundary such like cut is detected easily through any previous works. However, the videos with more than two types of shot and the large motion of camera or objects have difficulties in extracting the boundary between the adjacent shots. False alarms are increas...

An ocean general circulation model (oGCM) was used in concert with a global database of inert gas measurements (Ne, Ar, N2/Ar and Kr/Ar) to constrain the magnitude of bubble mediated air-sea gas flux. We illustrate the inverse method using a simple bubble model that includes two end member types of bubbles: small bubbles that completely dissolve, and larger bubbles that briefly are submerged an...

Cancer cells are irresponsive to the central control of cell growth mechanisms. It is difficult turn on responsive mechanism cancer because completely dissociated from command and their own in terms division growth. Precisely, this reason why they at risk health humans and/or any biological entities. Instead trying reconnect that already out range, we present a method for using cell’s uncontrol...
