sock while Fig. 8(b) shows a low-density sock. Improved injection tuning could provide a continuous high-density sock. Our hypothesis is CHM fabric, Fig. 8(c) , can be manufactured at a higher rate and with customized properties using particle injection. Besides showing the need to improve the stability of the particle injection, which is mainly a mechanical design problem, this experiment also indicated that mixing ferrocene with the NPs and injecting them separately from the fuel seems to make the sock formation more uniform as compared to injecting Zn NPs with the fuel in the mixer. A higher percentage of NPs can be injected when they are mixed with ferrocene. The optimal ratio of NPs to ferrocene, and the possibilities to compound NP mixtures using different metals need to be investigated. Overall, the CHM process is an emerging technology and some of the first results evaluating this new process are presented in this paper.

Computed elastic, ultrasonic and thermal properties are correlated to evaluate the microstructural behaviour of the materials useful for industrial applications. Graphical abstract The elastic, mechanical and thermal properties of Gd-doped ZnO nanorods (NRs) have been studied using Lenard Jones potential interaction potential model. The orientation dependent ultrasonic velocities and thermal relaxation time have been evaluated for the determination of anisotropic behaviour and thermophysical properties. The mechanical properties of the Gd-doped ZnO nanorods are better than at 6% Gd amount due to minimum attenuation.

This paper addresses the design of a reactor system for manufacturing carbon nanotube (CNT) fabric and carbon hybrid materials (CHM). A web or sock of CNT is formed in a reactor tube in the gas phase pyrolysis method. The sock exits the reactor tube and is wound layer by layer onto a drum to directly form a nonwoven fabric. Metal nanoparticles and continuous microfibers can be integrated into the synthesis process to form CHM. Continuous direct manufacturing of fabric is an advantage of the method. However, the reliability of this manufacturing process in our particular reactor system is affected by several problems. These include occasional breaking of the sock, the need for daily cleaning of the ceramic reactor tube due to carbon deposits on the inside, sagging/bending of the reactor tube, and safety in handling the hydrogen gas produced from the reaction. Possible solutions to the problems are proposed. The importance of this research is that no other bulk material has the combination of properties of CNT hybrid fabric. If the properties can be further improved and customized, and if manufacturing of the material can be scaled-up at reasonable cost, many new commercial applications for nanotube custom materials could open up.

Over the latter, gold interdigitated electrodes were patterned using ebeam evaporation and the lift-off technique. Reversible changes of current were caused by the presence or upon removal of chemical gases such as hydrogen (H 2 ) and carbon monoxide (CO).
