Abstract The addition of chalcone and amine components into indirubin-3′-oxime resulted in 15 new derivatives with high yields. Structures were also elucidated through 1D, 2D-NMR HR-MS(ESI) spectra X-ray crystallography. All designed compounds screened for cytotoxic activity against four human cancer cell lines (HepG2, LU-1, SW480 HL-60) one normal kidney line (HEK-293). Compound 6f exhibited the most marked cytotoxicity meanwhile 6e , 6h 6l was more profound toward than cell. These further...
We study the geometric structure and thermodynamic stability of Mo3Se132-@TM atomic clusters (TM = Sc, Ti, V, Cr, Mn, Fe, Co Ni) using B3LYP/LanL2DZ level within density functional theory. The presence transition metal in Mo3Se132- enhances mobility (Se-Se) terminals. Transition atoms preferentially attach to sites, which forms maximum number bonds with Se atoms. Dissociation energy entropy gradient analysis points out favor dissociate along two channels create either Se-TM or molecules....
Hydrothermal treatment and a reduction reaction to synthesize heterogeneous ZnO nanoplate (NPl)/Ag nanoparticle (NP) nanostructure for application in surface-enhanced Raman scattering (SERS).
Binary clusters of transition-metal and noble-metal elements have been gathering momentum for not only advanced fundamental understanding but also potential as elementary blocks novel nanostructured materials. In this regard, the geometries, electronic structures, stability, magnetic properties Cr-doped Cun, Agn, Aun (n = 2–20) systematically studied by means density functional theory calculations. It is found that structural evolutions CrCun CrAgn are identical. The icosahedral CrCu12...
Molecular and dissociative hydrogen adsorption of transition metal (TM)-doped [Mo3S13]2– atomic clusters were investigated using density functional theory calculations. The introduced TM dopants form stable bonds with S atoms, preserving the geometric structure. S-TM-S bridging bond emerges as most configuration. preferred sites found to be influenced by various factors, such relative electronegativity, coordination number, charge atom. Notably, presence these atoms remarkably improved...
The icosahedral structure of the Al x Sc y clusters with + = 13.
Increasing interest has been paid for hydrogen adsorption on atomically controlled nanoalloys due to their potential applications in catalytic processes and energy storage. In this work, we investigate the interaction of H2 with small-sized Ag n Cr (n = 1-12) using density functional theory calculations. It is found that cluster structures are preserved during either molecularly or dissociatively. Ag3Cr-H2, Ag6Cr-H2, Ag9Cr-H2 clusters identified be relatively more stable from computed...
A theoretical study of geometric and electronic structures, stability magnetic properties both neutral anionic Ge16M0/- clusters with M being a first-row 3d transition metal atom, is performed using quantum chemical approaches. Both the isoelectronic Ge16Sc- anion Ge16Ti that have perfect Frank-Kasper tetrahedral T d shape an electron shell filled 68 valence electrons, emerge as magic enhanced thermodynamic stability. The latter can be rationalized by simple Jellium model. Geometric...
Gold nano particles (GNPs) concentration dependence of the energy transfer occurs between fluorophores and GNPs is investigated. In case theses pairs, can enhance or quench fluorescence depending upon relative magnitudes two mechanisms: i) plasmonic field enhancement at emission frequencies (plasmon coupled enhancement) ii) localized plasmon Forster from fluorescent to gold particles, which quenches fluorescence. The competition these mechanisms on spectral overlap GNPs, their concentration,...

Modification of the chemical and physical properties with respect to element component in atomic clusters has paved way for great potential both fundamental study applications. An investigation on structure, stability magnetic gold doped by Cr Mo (Au12Cr Au12Mo) is discussed this work, using density functional theory calculation. The bond strength AuM dimers governs globally minimum structural evolution Au12M clusters, which can be classified into two principal forms: icosahedral (Mo dopant)...
The gate substrate effect on RF CMOS device noise is investigated. resistance (Rgb) contribution to the total minimum figures (NFmin) obtained. results show that considerable in a certain frequency range for 90 nm devices.
Au102+ and Au20 pyramids, whose stability inertness are comparable to those of carbon fullerene C60, considered as important landmarks in the long-history investigation gold nanoclusters. Numerous experimental theoretical studies on doping with transition metal atoms have been carried out for specific properties that can be used advanced materials nanotechnology applications. In this work, we discussed similarities differences between structural, stability, electronic Au9M2+ Au19M (M =...
The geometric structure, stability, dissociation channel and magnetism of AgnCo clusters (n = 1–12) have been studied using density functional theory. results show that the Co atom tends to choose highest coordination position. ground state prefers planar motif at small sizes less than 4) but favors 3D structures larger 5–12). stability is not only governed by symmetric geometry also strongly depends on electronic structure filling rule electron shells. Ag9Co cluster with 18 valence...
Magnetic force microscopy (MFM) has been used to probe the influence of an in situ applied in-plane elastic strains and/or magnetic field on static configuration a 530 nm magnetostrictive FeCuNbSiB thin film. The film shows typical stripe domain with 180 width presenting its moments oriented perpendicularly plane. strain was induced via application voltage piezoelectric (PE) actuator which film/substrate system glued. deposited onto compliant polyimide substrate (Kapton) order avoid clamping...
