(IF 2.169) Pub Date : 2018-12-07 Suresh Sagadevan, Zaira Zaman Chowdhury, Mohd. Rafie Bin Johan, Fauziah Abdul Aziz, Emee Marina Salleh, Anil Hawa, Rahman F. Rafique
In this research, a one step, facile route has been undertaken to synthesise copper oxide/reduced graphene oxide (CuO/rGO) nanocomposites. X-ray powder diffraction analysis (XRD) was carried out to identity the crystalline structure and phase of the synthesised sample. Elemental analysis and surface morphological features were analysed using EDX and FESEM Images. Particle size as well as the shape

Performance of Al2O3/TiO2 nano composite particles in domestic refrigerator J. Exp. Nanosci. (IF 2.169) Pub Date : 2018-12-06 K. Saravanan, R. Vijayan
This article presents an experimental investigation of domestic refrigerator using R134a as working fluid with different concentration of Al2O3, TiO2 nano particles and nano composite particles dispersed in polyolester (POE) oil lubricant. All the nano particles were added to the POE oil with 0.1gL−1 volume concentration. The experiments are conducted for different compositions such as R134a with POE

Preparation and characterisation of nano enhanced phase change material by adding carbon nano tubes to butyl stearate J. Exp. Nanosci. (IF 2.169) Pub Date : 2018-11-11 Soha Hashempour, Mohammad Hassan Vakili
A nano enhanced phase change material, NEPCM, was prepared by the addition of carbon nanotubes, CNTs, to butyl stearate. This study utilised single walled nano tube, multi-walled nanotube and modified multi-walled nanotube. Several kinds of surfactants were used to stabilise nano-particles in butyl stearate. Tetramethyl ethylene diamine (TEMED) was the best surfactant for enhancing the stability time

Production of alumina micro abrasives coated with nano-silica for bonding improvements to zirconia J. Exp. Nanosci. (IF 2.169) Pub Date : 2018-11-11 Zhang Wei, Ahmad Farooq, Wu Wangping, Kong Dejun
Tribochemical silica coating is a common practice to achieve suitable adhesion with intended synthetic substrates or natural tissues, and the key to this technology is the preparation of alumina abrasive coated by nano-silica (AACNS). In this paper, a novel physical method of producing silicon nanoparticles (SiNPs) that is the base to AACNS is put forward in this paper. The source of the silica coating

Low-cost and facile implementation of microfluidic colour-changing devices using dry film photoresist-based moulds J. Exp. Nanosci. (IF 2.169) Pub Date : 2018-11-11 Min Zhang, Songjing Li
In this work, different microfluidic colour-changing devices are implemented by using dry film photoresist-based moulds instead of standard photolithography moulds. EtertecHT-115T negative dry film photoresist is employed to realise the rapid fabrication of the moulds for colour-changing layers. The major factors that may affect the fidelity of the dry film moulds during fabrication are summarised

Microemulsion-based synthesis of strontium hexaferrite cobalt iron oxide nanoparticles and their biocompatibility in albino mice J. Exp. Nanosci. (IF 2.169) Pub Date : 2018-11-01 Sana Akhtar, Sehrish Saba, Sauma Rehman, Ahmad Hassan, Noreen Samad, Muhammad Amir, Mudassar Akram, Maryam Ijaz, Kiran Asif, Muhammad Naeem Ashiq, Furhan Iqbal
A number of strontium-based iron oxides are available for the industrial use. Among them, strontium hexaferrite cobalt iron oxide (Sr2Co2Fe12O22) is preferred over others due to its better magnetic and electrical properties than others. This material is also extensively used for the absorption of microwave radiations. This study was conducted to account for the synthesis and characterization of Sr2Co2Fe12O22

Microstructure and properties of BN/Ni-Cu composites fabricated by powder technology J. Exp. Nanosci. (IF 2.169) Pub Date : 2018-05-28 Ahmed El-Tantawy, Walid M. Daoush, Ahmed E. El-Nikhaily
Microsize Powders of Ni and Cu were prepared by water atomization technique to fabricate metal matrix composites containing various percentages of nanosized boron nitride particles (1, 2, 3, 4, 5 wt. % of BN in a matrix containing (20 wt. %Ni and 80 wt. %Cu). The prepared mixtures were cold compacted under 400 MPa, and sintered for 2 h at 1000 °C in a controlled atmosphere of 3:2 N2/H2 gas mixtures

Fault detection and analysis of bistable rotaxane molecular electronic switch - A simulation approach J. Exp. Nanosci. (IF 2.169) Pub Date : 2018-04-25 Devisree S, Anand Kumar
As the transistor size approaches nano dimension, short channel effects become dominant in micro devices, leading to an incessant struggle to keep pace with Moore's law. This paved way to development of newer technologies like molecular electronics. The self-assembled bottom-up approach makes molecular switches more prone to defects than micro devices. The widely studied molecular switches are mechanically

The synthesis of nano-sized ZSM-5 zeolite by dry gel conversion method and investigating the effects of experimental parameters by Taguchi experimental design J. Exp. Nanosci. (IF 2.169) Pub Date : 2018-04-25 Farshid Mohammadparast, Rouein Halladj, Sima Askari
In this study ZSM-5 Nano particles with high crystallinity were synthesized using a dry gel conversion technique. An L9 orthogonal array of the Taguchi method was applied to investigate the effect of synthesis parameters, such as crystallization time, gel drying temperature, molar composition of template (TPAOH) and water content in the crystallization stage on crystallinity and particle size of the

Dispersion and sedimentation of titanium dioxide nanoparticles in freshwater algae and daphnia aquatic culture media in the presence of arsenate J. Exp. Nanosci. (IF 2.169) Pub Date : 2018-04-09 Zhenhong Wang, Zhuanxi Luo, Yamen Yan
Little information is available on Titanium dioxide nanoparticles (nTiO2) behavior in different culture media for aquatic organisms. This study aimed to accurately evaluate nTiO2 dispersion and sedimentation in common freshwater algae (BG-11) and daphnia aquatic (SM7) culture media. We additionally investigated potential mechanisms of nTiO2 stability under arsenate influence. Results showed that high
