Temperature profile and boundary conditions in an anomalous heat transport model
Abstract A framework for studying the effect of the coupling to the heat bath in models exhibiting anomalous heat conduction is described. The framework is applied to the harmonic chain with momentum exchange model where the non-trivial temperature profile is calculated. In this approach one first uses the hydrodynami…
Crystallographic textures
In material science, crystallographic texture is an important microstructural parameter which directly determines the anisotropy degree of most physical properties of a polycrystalline material at the macro scale. Its characterization is thus of fundamental and applied importance, and should ideally be performed prior…
Preparing local strain patterns in graphene by atomic force microscope based indentation
Patterning graphene into various mesoscopic devices such as nanoribbons, quantum dots, etc. by lithographic techniques has enabled the guiding and manipulation of graphene's Dirac-type charge carriers. Graphene, with well-defined strain patterns, holds promise of similarly rich physics while avoiding the problems crea…
Green Synthesis of Copper Nanoparticles Using Solanum Lycopersicum (Tomato Aqueous Extract) and Study Characterization
The biosynthesis of copper nanoparticles is applicable in a number of the field. In the study, we experiment the reducing and capping activity of aqueous extract from tomato juice for the preparation of copper nanoparticles. The extract with different concentration reduced the aqueous solution at room temperature. Che…
Impact of Stone Wash and Acid Wash on the Physical Properties of Denim
The aim of this paper is to find out the changes occurs in physical properties of denim when it is subjected to stone and acid wash or to find out the impact of stone and acid wash. 100% cotton twill, weave 2/1, construction 80 × 64/10 × 9, indigo dyed denim fabric leg panels as per lab standard recipe are used here t…
Compositional dependency on dissolution rate and cytocompatibility of phosphate-based glasses: Effect of B 2 O 3 and Fe 2 O 3 addition
The unique property of phosphate-based glasses and fibres to be completely dissolved in aqueous media is largely dependent on the glass composition. This article focuses on investigating the effect of replacing Na 2 O with 3 and 5 mol% Fe 2 O 3 on cytocompatibility, thermal and dissolution properties of P 2 O 5 –CaO–N…
Micro-tubular flame-assisted fuel cells
Micro-tubular solid oxide fuel cells operating in fuel-rich combustion exhaust are explored in this work and their benefits in reducing the balance of plant in fuel cell systems is discussed. The current state of performance of these micro-tubular flame-assisted fuel cells operating with methane fuel is described and…
The diffusion behavior and capacitance of tetraethylammonium/tetrafluoroborate ions in acetonitrile with different molar concentrations: a molecular dynamics study
A molecular dynamics (MD) simulation with the optimized potentials for liquid simulations-all atom (OPLS-AA) force field was carried out to investigate the dynamic behaviors of organic electrolyte molecules between a graphite cathode and anode.
EQCM and RDE/RRDE Study of Soluble Iron Phthalocyanine Bifunctional Catalyst for the Lithium-Oxygen Battery
Soluble iron phtalocyanine (FePc) has been studied as a bifunctional catalyst for the oxygen reduction reaction (ORR) and oxygen evolution (OER) in lithium air cathodes by means of electrogravimetry with shear wave dissipation, cyclic voltammetry (CV) and rotating ring disk electrode (RRDE). The oxygen reduction react…
Large-scale synthesis of polyhedral Ag nanoparticles for printed electronics
The large-scale synthesis of polyhedral Ag nanoparticles (NPs) described here follows a mediated-particle mechanism and the formulation of NPs in high volume fraction ink easily forms highly electrically conductive lines for printed electronics.
Extraction of Migration Energies and Role of Implant Damage on Thermal Stability of Deuterium in Ga2O3
Deuterium was incorporated in bulk single crystal β-Ga 2 O 3 samples by either ion implantation (100 keV, 10 15 cm −2 ) or plasma exposure (up to 270°C, 30 mins) of single-crystal β-Ga 2 O 3 and then its stability was examined as a function of annealing temperature. The mechanisms in both cases were extracted by fitti…
Triple band regular decagon shaped metamaterial absorber for X-band applications
In this research work, the design characterization of metamaterial absorber has been investigated for X-band applications. For this purpose, a primary regular decagon shaped loop structure has chosen and its multi band response has been studied and analyzed. The simulated results show that absorption peaks occur at 8…
