Dye Sensitized Solar Cell (DSSC) based on metal oxide photo anode is of greater interest at the present scenario. The light harvesting capability of the photo anode is the most crucial factor in determining the efficiency of DSSC. Thus to decide on suitable photo anode to attain greater efficiency is critical confront…
Three-dimensional porous polycaprolactone (PCL) scaffolds with consistent inter-pore channels, 83% porosity and 300–400 μm pore size were fabricated via selective laser sintering. The PCL scaffold was combined with platelet-rich plasma (PRP) to form a bioactive composite and studied for potential application in bone t…
This work reports hydrogen adsorption properties of four different metal–organic frameworks (MOFs) namely Zn-BDC, Cr-BDC, Ni-DABCO, and Mg-DOBDC. Gravimetric hydrogen adsorption measurements are performed over a wide range of temperature (90 K to 298 K) and pressure (0 bar to 100 bar). At the lowest experimental tempe…
Elucidation of the flow mechanism of the supercooled liquid near the glass transition temperature Tg is crucial for understanding the nature of glass transition. Dynamic facilitation between adjacent flow events in the supercooled liquid is believed to be crucial in the process of glass transition. In this work, it is…
Dye sensitized solar cell (DSSC) devices incorporating organic and inorganic materials have found a host of applications. The search for low-cost, high efficient and flexible devices has lead to a remarkable increase in the research and development of solar cell. The current review, describes the constitution componen…
C4-H and C5-H protons of the imidazolium heterocycle have been exploited as a binding site for anion recognition in the design of two new redox-active imidazoliophane syn and anti isomers. The cooperative action of the two imidazolium motifs of the syn isomer is crucial for halide anion recognition. The integration of…
The efficiency of the best Dye sensitized solar cell is primarily depends on the good light harvesting property of the photo anode. Present study uses Lawsone (2 hydroxy [1, -naphthoquinone), the natural dye and compare the performance of photo anode in bare TiO 2 and with nanoporous CaCO 3 coated TiO 2 . As compared…
Abstract Abstract: Tungsten-copper (W-Cu) composite and 1Cr18Ni9 stainless steel were brazed with Ag-28wt%Cu brazing filler metal in a vacuum furnace, via controlling brazing temperature 855–865 °C and holding time 30 min. Microstructure, microhardness, four-point bend strength, element distribution and phase constitu…
ABSTRACT This study presents a promising ultraviolet (UV)‐curable epoxy resin formulation with improved flame‐retardant properties. The formulation is based on the cycloaliphatic epoxide 3,4‐epoxycyclohexylmethyl‐3,4‐epoxycyclohexane carboxylate (ERL4221) and a novel silicon, phosphorous containing flame‐retardant add…
H2 und O2 werden H2O2: Die direkte Synthese von Wasserstoffperoxid aus Wasserstoff und Sauerstoff in Wasser gelingt mit dem IrIII-Komplex [IrIII(Cp*)(4-(1H-Pyrazol-1-yl-κN2)benzoesäure-κC3)(H2O)]2SO4 und Flavinmononucleotid. Die Methode liefert Wasserstoffperoxid mit hoher Umsatzzahl (847) und Ausbeute (19.2 %) bei Um…
We investigate the flux pinning mechanism for single-crystalline MgB2 thin films showing a peculiar flux pinning force behavior. The vortex–vortex distance is considered in this study through an analysis of the critical current density (\(J_{\text{c}}\)) and the flux pinning force density (\(F_{\text{p}}\)) over a wid…
BACKGROUND: Type IV collagen is important for the structural integrity and function of basement membranes. Basement membranes surround vascular smooth muscle cells in the media, COL4A1 is the most abundant component of type IV collagen in all Basement membranes. However, the relationship between COL4A1 genetic polymor…
This paper describes the construction, fabrication and properties of large-area ultra violet detector that is transparent in the visible range. The device was made on n-type 4H SiC substrate with a double epitaxial layer in which aluminum was implanted to form a p-n junction close to the surface, and a SiO2 layer was…
Using molecular simulations, we investigate the structural and diffusive dynamics properties of a model fluid in highly absorptive cylindrical pores. At subcritical temperatures, self-diffusivity displays three distinct regimes as a function of average pore density ρ: (1) a decrease in self-diffusivity with increasing…
This paper reports the use of thin titania or alumina coatings on tin oxide nanowire arrays for high cyclability electrodes for lithium-ion batteries. We demonstrate that such coatings can significantly reduce irreversible capacity loss associated with the formation of a solid electrolyte interface and improve the cap…
Polycaprolactone/silica microporous hybrid membranes were produced in two steps: A microporous polycaprolactone membrane with an interconnected porosity of 80% was obtained via a freeze extraction procedure, then silica was formed by a sol-gel reaction inside the micropores using tetraethyl orthosilicate, TEOS, as sil…
BACKGROUND: Chronic venous insufficiency (CVI) represents a major global health problem with increasing prevalence and morbidity. CVI is due to an incompetence of the venous valves, which causes venous reflux and distal venous hypertension. Several studies have focused on the replacement of diseased venous valves usin…
Group I metabotropic glutamate receptors (mGluR1/5) play a role in synaptic plasticity and they demonstrate direct interactions with the neuronal Homer1c protein. We have previously shown that Homer1c can restore the plasticity deficits in Homer1 knockout mice (H1-KO). Here, we investigated the role of Homer1c in mGlu…
In this study, post-buckling behavior of functionally graded beams under the influence of temperature loading is investigated by using total Lagrangian finite element model of three-dimensional continuum approximations. Material properties of the beam are both temperature-dependent and position-dependent. In this stud…
