TL;DR: In this paper, multwall carbon nanotubes (MWCNTs) were used as the electrodes of flow-through capacitors (FTCs) for desalination, and the morphological structure of MWCNTs was investigated by transmission electron microscopy, X-ray diffraction, and Raman spectroscopy.

TL;DR: The result of the present method is shown to be equivalent to the empirical method proposed by Davison EJ, which is based on the static decoupler design followed by SISO PI/PID controllers design and combining the resulted decoupling and the diagonal PI(D) controllers as the centralized controllers.
Abstract: A method is given to design multivariable PI/PID controllers for stable and unstable multivariable systems. The method needs only the steady state gain matrix (SSGM). The method is based on the static decoupler design followed by SISO PI/PID controllers design and combining the resulted decoupler and the diagonal PI(D) controllers as the centralized controllers. The result of the present method is shown to be equivalent to the empirical method proposed by Davison EJ. Multivariable tuning regulators: the feed-forward and robust control of general servo-mechanism problem. IEEE Trans Autom Control 1976;21:35–41. Three simulation examples are given. The performance of the controllers is compared with that of the reported centralized controller based on the multivariable transfer function matrix.

TL;DR: In this article, a new type of carbon fabric supported functionalised multiwalled carbon nanotubes (f-MWNTs) based supercapacitor was developed, and this setup was tested for desalination of sea water.
Abstract: In order to investigate the simultaneous adsorption property of functionalised multiwalled carbon nanotubes (MWNTs) for sodium and arsenic, a new type of carbon fabric supported functionalised MWNTs (f-MWNTs) based supercapacitor was developed. In addition, this setup was tested for desalination of sea water. MWNTs were synthesised by chemical vapour deposition technique and purified, followed by functionalisation. MWNTs were characterised by different techniques. Performance of supercapacitor-based water filter was analysed for the adsorption of high concentration of arsenic (trivalent and pentavalent) and sodium as well as for desalination of sea water by using cyclic voltametry and inductively coupled plasma-optical emission spectroscopy techniques. Adsorption isotherms and kinetic characteristics were studied for the simultaneous removal of sodium and arsenic. High desalination (removal of sodium and magnesium) efficiency of sea water and cyclic repeatability for simultaneous removal of arsenic (arsen...
