The influence of the Ce 3+ concentration on the excitation and emission characteristics, thermal stability, and charge-trapping–detrapping dynamics, of the green-emitting phosphor Ce 3+ doped calcium scandium oxide (CaSc 2 O 4 ) with very dilute Ce 3+ substitutions (0.5, 1.0, and 1.5%), has been investigated using opt…
Here, we report a comprehensive study of the fundamental optical properties of two-dimensional materials. These properties have been ascertained using spectroscopic ellipsometry, optical spectroscopy of Raman scattering, and photoluminescence. We have focused on the optical properties of the chemically exfoliated laye…
High Resolution Image Download MS PowerPoint Slide NiCo 2 O 4 nanostructure is a widely studied pseudocapacitor material because of its high specific capacitance value. Most of the time, the thickness of the nanostructure inhibits the electrode material from whole-body participation and causes sluggish charge transpor…
Abstract Carbon fiber (CF) reinforced carbon-silicon carbide (C/C-SiC) composites are one of the most promising lightweight materials for re-entry thermal protection, rocket nozzles and brake discs applications. In this paper, a novel sandwich-structured C/C-SiC composite, containing two exterior C/SiC layers, two gra…
Energy evaluation of charged defects is tremendously important in two-dimensional (2D) semiconductors for the industrialization of 2D electronic devices because of its close relation with the corresponding type of conductivity and its strength. Although the method to calculate the energy of charged defects in single-l…
Ladder-type and chain 2p–3d–4f complexes based on a bridging nitronyl nitroxide radical, namely, [LnCu(hfac) 5 (NIT-Ph- p -OCH 2 trz)]·0.5C 6 H 14 [Ln = Y ( 1a ), Dy ( 1b )] and [LnCu(hfac) 5 (NIT-Ph- p -OCH 2 trz)] [Ln = Y ( 2a ), Dy ( 2b ); NIT-Ph- p -OCH 2 trz = 2-[4-[(1 H -1,2,4-triazol-1-yl)methoxy]phenyl]-4,4,5,…
High Resolution Image Download MS PowerPoint Slide The fabrication of polymeric nanofibers and its potential versatility instigated to foster smart hybrid nanomaterials for the removal of environmental pollutants. In this pursuit, in this research work, polyacrylonitrile (PAN)-based two-dimensional (2D) nanofibrous ma…
The fundamental phase transition mechanism and the stability of the semiconductor-to-metal phase transition properties during multiple thermal cycles have been investigated on epitaxial vanadium dioxide (VO2) thin films via both ex situ heating and in situ heating by transmission electron microscopy (TEM). VO2 thin fi…
(temperature at 50% weight loss) of PP/AMO-stearic-LDH (20 wt%) nanocomposites dramatically increased by 80 °C compared to that of neat PP. The flame retardant performance was dependent on both surfactants and the loading of LDHs. The AMO-stearic-LDHs showed better flame retardant properties than the AMO-DDS-LDHs, esp…
Caffeine-oxalic acid cocrystal, widely reported to be stable under high humidity, dissociated in the presence of numerous pharmaceutical excipients. In cocrystal-excipient binary systems, the water mediated dissociation reaction occurred under pharmaceutically relevant storage conditions. Powder X-ray diffractometry w…
Advances in electrocatalyst functionality have resulted from the evolution of complex nanostructured materials with increasing degrees of compositional and morphological complexity. Focused almost entirely on pushing the boundaries of intrinsic activity, electrocatalytic material development often overlooks stability.…
The impact of partial miscibility on viscous fingering dynamics is studied, demonstrating that the coupling between viscous and compositional effects lead to a rich set of displacement patterns. Snapshots of mixture concentration at various initial compositions and log-mobility ratios are shown.
A series of platinum(II) terpyridine complexes with tetraphenylethylene-modified alkynyl ligands has been designed and synthesized. The introduction of the tetraphenylethylene motif has led to aggregation-induced emission (AIE) properties, which upon self-assembly led to the formation of metal-metal-to-ligand charge t…
Anomalous (non-Fourier) heat transport is no longer just a theoretical issue since it has been observed experimentally in a number of low-dimensional nanomaterials, such as SiGe nanowires, carbon nanotubes, and others. To understand these anomalous behaviors, exploring the microscopic origin of normal (Fourier) heat t…
Control of the hierarchical molecular organization of polydiarylfluorenes by synthetic strategies is significant for optimizing photophysical properties as well as the performance of light-emitting devices. Herein, for the suppression of molecular aggregation and enhancement of luminescence efficiency, a series of ste…

GGAG:Ce nanoscintillator has been chosen because of its high light output and fast decay time. The nanopowder of GGAG is synthesized by coprecipitation method and dispersed in the polymer ma…
The contact between liquid drops and hot solid surfaces is of practical importance for industrial processes, such as thermal spraying and spray cooling. The contact and bouncing of solid spheres is also an important event encountered in ball milling, powder processing, and everyday activities, such as ball sports. Usi…
