TiO2 particles have been added in molten aluminium to result in aluminium based cast Al/Al3Ti-Al2O3 composite, which has been added then to molten magnesium to synthesize magnesium based cast Mg-Al/Al3Ti-Al2O3 composite. The nominal compositions in terms of Mg, Al, and TiO2 contents in the magnesium based composites a…
Supercapacitors, a class of electrochemical energy storage devices with superior power densities and long cycling lifetimes, have attracted great attention for the last decade due to their widespread application in backup power supply systems, portable devices, power tools, and hybrid electric vehicles. Graphene is co…
The successful development of novel materials for polymer electrolyte membrane fuel cell (PEMFC) electrodes is hindered by the lack of a fundamental understanding of the complex, multicomponent nature of the catalyst layer (CL), the interplay of its components, and their independent and cooperative effects on the effe…
Electrochemical Promotion of Catalysis (EPOC), also called Non-Faradaic Electrochemical Modification of Catalytic Activity (NEMCA), is a promising concept for boosting catalytic processes and advancing the frontiers of catalysis [1]. This innovative field aims to modify in-operando both the activity and the selectivit…
Zinc oxide (ZnO) is a conductive oxide, which serves as the n-type semiconductor. Furthermore, ZnO has other favorable properties including high electron mobility, stability, and good transparency. We were introduced the new electrolyte composition (previous conferences), which is far more dilute than systems that had…
Quantum entanglement has been visualized for the first time, in view of the spin density distribution and electronic structure for manganese in manganese( II )hexakisimidazole nitrate. Using polarized neutron diffraction and density functional theory modelling we have found for the complex, which crystallizes in the R…
Three kinds of three-dimensional (3D) CuxO catalysts were prepared to modify activated carbon air-cathode using a facile electrochemical method with addition of surfactants. The maximum power density of MFC using SC-Cu air cathode (added sodium citrate into the electrolyte solution in eletrodeposition process) was 155…
Introduction The decreasing supply of fossil fuel sources, coupled with the increasing concentration of green house gases has placed enormous pressure to maximize the efficiency of power generation (1). Increasing the outlet temperature of these power plants will result in an increase in Carnot efficiency (2). To incr…
Ever since their discovery, carbon nanotubes (CNTs) have been touted as a material of the future and a lengthy list of possible applications are often cited in the literature. However, the realization of these applications have so far been hindered by exactly the property which made CNTs so attractive in the first pla…
High contact resistance between TMDs and metals has been identified as an outstanding issue. TMDs tend to form a substantial Schottky barrier (SB) with commonly used metals. Air-stable graphene electrodes stacked on the WSe2 by transfer technique have been reported. However, unipolar conduction has not been achieved i…
Recently, transition metal dichalcogenide (TMDC) monolayers, such as molybdenum disulfide (MoS2) and tungsten diselenide (WSe2), have attracted strong attention as novel two-dimensional (2D) semiconducting materials due to their large bandgap (1−2 eV) and excellent transport properties. Moreover, the thickness of mono…
At present, single-mode optical fibers composed of metamaterials—so-called “left-handed” optical media—for the far- and mid-IR ranges have already been created. In the near future, left-handed singlemode optical fibers for the visible and near-IR ranges will be created, light-carrying cores of which will be composed b…
Since the onset and progression of cancer and many other diseases involve dysregulation of certain sub-cellular compartments, accurate visualization of events using probes localized in sub-cellular organelles would facilitate the understanding of disease processes. Molecular probes based on single-walled carbon nanotu…
Silicon nanocrystals (SiNCs) have been attracting attention as active materials in a variety of proto-type devices including, solar cells, light-emitting diodes, and photodetectors. These, and other device structures require well-defined materials with predictable properties. Traditionally SiNC surfaces are rendered p…
Two-dimensional transition metal dichalcogenides (TMDs) have moved to the foreground of the research community owing to their fascinating properties which make them of great interest for both fundamental studies and emerging applications. Thermally assisted conversion (TAC) of predeposited transition metal films and C…
The use of redox mediators is a well-established approach in electrosynthesis to lower kinetic barriers, to improve product selectivity and to suppress electrode fouling.[1] Recently we have developed a new series of metal‐free and easy-to-synthesize redox mediators based on the phenanthro[9,10-d]imidazole framework (…
With the recent development of high-performing Pt-based electrocatalysts, fuel cells for automotive applications are becoming increasingly viable, and understanding the multiple mechanisms contributing to catalyst degradation is a priority to enable further catalyst optimization. In this respect, the 3D structure of t…
Solid-state electrolytes that can perform on par with conventional liquid electrolytes are highly sought after for use in all solid-state batteries. An all solid-state battery promises to operate without the possibility of catastrophic failure and have substantially longer self-life than conventional batteries. The Li…
Geometry optimization, electronic and nonlinear optical properties of isomers of furyloxazole and thienyloxazole molecules are carried out at the B3LYP/6-311++G(2d,p) level. The conformational analysis of 12 compounds have been studied as a function of torsional angle between rings. Electronic and NLO properties such…
In recently years, there has been a robust attention in clean and renewable energy sources due to heavy dependence on finite fossil fuels as our major source of energy, causing serious energy and environmental crisis such as emission of CO2 and NO x on the world. Hydrogen is attracted as a leading candidate for altern…
