Plasma electrolytic oxidation(PEO)coatings were carried out in silicate-based electrolyte embedded with various amounts of carbon nanotube(cNT)additives(0,0.5,1,2 and 4 g/L)on AZ80 magnesium alloy ***,tribological and electrochemical corrosion properties of the coated specimens were *** results demonstrated that the increasing cNT additions into the electrolyte resulted in a gradual increase in the thickness of PEO-coating *** cNT addition to the electrolyte by 0.5 g/L resulted in a slight decrease in the roughness of PEO-coating above which it continually *** resistance of the PEO-coated specimens showed a gradual improvement with increasing cNT-incorporation within the *** electrochemical corrosion tests revealed that the best corrosion resistance was found after the cNT addition into the electrolyte by 0.5 g/L due to the better roughness values,more homogenous coating layers and less pore formation.

As environmental concerns from fossil fuel consumption intensify, large-scale energy storage becomes imperative for the integration of renewable sources like wind, hydro, and solar with the electrical *** flow batteries, particularly those employing organic molecules, are positioned as a key technology for this purpose. This review explores the growing field of symmetric organic redox flow batteries(ORFBs) within this context. Unlike traditional asymmetric designs based on unique active materials for each electrode, symmetric ORFBs involve a single bipolar species for both electrodes. This review highlights the benefits of a symmetric design, and categorizes five distinct classes of organic bipolar molecules used in both aqueous and non-aqueous solvents. By providing a comprehensive overview of their cell cycling and performance characteristics, the strengths and weaknesses of the diverse categories of bipolar molecules are highlighted for both solvent systems, as are opportunities for future development. This should guide new research directions and advance the development of practical symmetric ORFBs.

Shape memory polymer （SMP） blends based on polyurethane （PU） and polyaniline （PANI） were prepared via chemical in situ polymerization process. The thermal, mechanical, electrical and shape memory properties were investigated. The structural characterization and morphology of the polymer blends were inspected by Fourier transform infrared （FTIR） and scanning electron microscopy （SEM）, respectively. The 1 wt% of PANI loading enhanced the thermal stability of the system up to 339 ~c. According to differential scanning calorimetry （DSc）, the glass transition temperature （Tg） and melting temperature （Tm） of PU/PANI blends increased with the polyaniline loading （0.1 wt%-l wt%）. Improved mechanical properties such as tensile strength and Young＇s modulus of PU matrix were also observed with PANI. Moreover, the electrical conductivity of PU/PANI blends was also found to be a function of PANI loading. Remarkable recoverability of thermally triggered shape memory （SM） behavior to the extent of 96% was achieved for 1 wt% PANI blend.

Mixed ammonium-transition metal salts with formula of （NH4）xMyHzPMo12O40 （M = Ni^2＋, co^2＋ or Fe ^3＋） denoted as MPMo12 have been investigated for the oxidation of propane, with molecular oxygen, at temperature range between 380 ℃ and 420 ℃ after in-situ pre-treatment performed at two heating rate of 5 or 9℃/min. They were characterized by BET method, XRD, UV-Vis and IR techniques. The catalysts were found to be active in the propane oxidation and selective to propene or acrolein, in particular for samples pre-treated with the heating rate of 9℃/min. FePMo12 was found to be a more active catalyst for propene （17.2% yield） with minimal over deep oxidation （0.3% yield in cOx）.

Diffuse idiopathic skeletal hyperostosis(DISH) is a noninflammatory disease characterized by calcification and ossification of soft tissues, mainly enthesis and spinal ligaments. The clinical presentation primarily includes spinal involvement-induced pain and range of motion. Although rare, life-threatening gastrointestinal, respiratory or neurological events or severe morbidity due to bone compression on the adjacent structures may develop. There is a limited amount of data on DISHrelated events in the literature. In recent years, comorbid metabolic disorders are of great interest in patients with DISH. The early diagnosis of these conditions as well as rare entities allows an effective multidisciplinary approach for the treatment of DISH. In this article, we review extraskeletal symptoms and associated comorbidities in patients with DISH.

We investigate the time evolution of entanglement between two quantum dots in an engineered vacuum environment such that a metallic nanoring having a surface plasmon is placed near the quantum dots. Such engineering in environment results in oscillations in entanglement dynamics of the quantum dots systems. With proper adjustment of the separation between the quantum dots, entanglement decay can be stabilized and preserved for longer time than its decay without the surface plasmons interactions.
