This study investigates the energy relations and dissipations in viscoelastic pipeline under fluid transients. The investigation is carried out analytically using energy analysis and Fourier transform techniques for viscoelastic waterhammer governing equations. The analytical results show that the viscoelastic term in…
Redox shuttle is a promising mechanism for intrinsic overcharge protection in lithium-ion cells and batteries. Two lithium borate cluster salts are reported to function as both the main salt for a nonaqueous electrolyte and the redox shuttle for overcharge protection. Lithium borate cluster salts with a tunable redox…
One of the main applications in plasma physics concerns the energy production through thermonuclear fusion. The controlled fusion requires the confinement of the plasma into a bounded domain, and for this we appeal to the magnetic confinement. Several models exist for describing the evolution of strongly magnetized pl…
The Effect of Passivation Layers on the Negative Bias Instability of Ga–In–Zn–O Thin Film Transistors under Illumination, Jung, Ji Sim, Lee, Kwang-Hee, Son, Kyoung Seok, Park, Joon Seok, Kim, Tae Sang, Seo, Jong Hyun, Jeon, Jae-Hong, Hong, Mun-Pyo, Kwon, Jang-Yeon, Koo, Bonwon, Lee, Sangyun
and ternary alloys are studied using density functional theory and compared with the bimetallic and alloys to determine the effect of the substitution of platinum by iridium on surface adsorption properties and catalytic activity toward the oxygen reduction reaction (ORR) as well as electrochemical stability against d…
In the recent decades, there has been a growing interest in micro- and nanotechnology. The advances in nanotechnology give rise to new applications and new types of materials with unique electromagnetic and mechanical properties. This book is devoted to the modern methods in electrodynamics and acoustics, which have b…
During more than five decades of deployment, a great deal of both scientific and engineering insight has been gained into the application of solvent extraction to the challenge of processing spent nuclear fuel. Though no chemical separation process is without limitations, the ability to employ continuous operations, t…
A Generalized Langevin Equation with exponential memory is proposed for the dynamics of a massive intruder in a dense granular fluid. The model reproduces numerical correlation and response functions, violating the Equilibrium Fluctuation-Dissipation Relations. The source of memory is identified in the coupling of the…
[EN] Little is currently known about the population structure of lichen photobionts. Accordingly, in this study we analyzed the nature and distribution of phycobionts in different Spanish populations of Ramalina farinacea. Two different Trebouxia algae were isolated and identified on the basis of anatomical and chloro…
A new fluorescent chemosensor 3 based on calix[4]arene of partial cone conformation possessing dansyl moieties has been synthesized. The chemosensor demonstrates selective optical recognition of Hg(2+) ions in mixed aqueous media and mimics the operation of a traffic signal based on the R-S Latch Logic circuit with pH…
The synthesis and characterization of hollow Pd–Co bimetallic nanospheres are reported. During Sonogashira-type coupling reactions between aryl halides and terminal alkynes in aqueous medium, these hollow materials exhibited much higher activity than the solid counterpart nanoparticles. Moreover, the catalytic activit…
A new anthracene-based ligand shows emission shift and decrease of excimer band upon coordination to silver ions when crystallized from methanol. Changing the solvent leads to the formation of amorphous nanowires exhibiting large emission bands before transforming into a second crystalline compound with excimer emissi…
The preparation, characterization and catalytic reactivity of a GaN supported Pt catalyst in the hydrogenation of ethene are presented in this feature article, highlighting the use of in situ characterization of the material properties during sample handling and catalysis by combining temperature programmed reaction w…
Tetrakis[4-(carboxymethyleneoxy)phenyl]porphyrin, a flexible tetraacid ligand, is a new attractive building block for the formulation of coordination polymers and hydrogen bonding supramolecular assemblies in the solid state.
A supramolecular approach based on the self-assembly of a hydrogen bonding switch with unsaturated pyridyl compounds is exploited in order to drive the topochemical synthesis of head-to-tail photodimers via charge-assisted hydrogen bonds.
A xylene decomposition system that combines a process of adsorption with a process of decomposition by nonthermal plasma with gas circulation is investigated for treating volatile organic compounds exhaust from indoor small-scale sources. An ac 60-Hz neon transformer and an inverter-type neon transformer are used for…
The effect of trace Al, V, Sn and Si addition on the grain refinement, hardness, and lattice strain was discussed. From the results of variation in the average grain size, it was found that the growth restriction factor of individual additions is Si>Al>Sn>V in order of their magnitude. The c⁄a ratio of other Ti alloys…
Scattering of electromagnetic plane waves from an inflnitely long nihility cylinder, coated with a chiral layer of uniform thickness, is presented. Cylindrical vector wave functions have been used to express the flelds in difierent regions. The solution is determined by solving the wave equation for difierent regions…
Thin silicate films with immobilised enzymes catalysing dioxygen reduction, i.e. laccase and bilirubin oxidase (BOD), were deposited on glass and poly(methyl 2-methylpropenoate) (Plexiglas) surfaces in a sol-gel process by sol drop evaporation. Scanning electrochemical microscopy (SECM) images and approach curves were…
Ligand design principles based on acyclic conformational analysis, dynamic stereochemistry, and hard-soft ligand-metal coordination have led to the development of several redox-triggered chiroptical molecular switches. Factors controlling the helicity of copper(I) and copper(II) coordination complexes were explored an…
