We analyze the size effect on spin-crossover transition nanoparticles in a 2D Ising-like model subject to a specific ligand-field at the surface. By anisotropic sampling method applied to the finite 2D square Ising lattices with various sizes, we determined the density of macro states by scanning the spin configuratio…
The electric field-assisted flash sintering method recently introduced in the literature was here considered for producing high-quality CaCu3Ti4O12 electroceramics, from a powder originally synthesized by a Pechini-derived method and calcined at 800 °C for 2 h. The study included analyzing the dynamics of material shr…
In-chain poly(phosphonate)s have been prepared via acyclic diene metathesis polymerization of three different monomers. Novel unsaturated phosphonate monomers with asymmetric structure have been developed. The monomers are accessible via a three-step synthesis that can be easily scaled up. This is the first report on…
Ordered heterostructures of layered materials where interlayers with different reactivities strictly alternate in stacks offer predetermined slippage planes that provide a precise route for the preparation of bilayer materials. We use this route for the synthesis of a novel type of reinforced layered silicate bilayer…
The local segmental and global dynamics of a series of polypropylene glycol/silica nanocomposites were studied using rheometry and mechanical and dielectric spectroscopies. The particles cause substantial changes in the rheology, including higher viscosities that become non-Newtonian and the appearance of stress overs…
In this paper, the electrical properties of Ti3SiC2-based ohmic contacts formed on p-type 4H-SiC were studied. The growth of Ti3SiC2thin films were studied onto 4H-SiC substrates by thermal annealing of Ti-Al layers deposited by magnetron sputtering. In this study, we varied the concentrations of Ti and Al (Ti20Al80,…
Scrutinizing critical thermodynamic and kinetic factors for glass formation and the glass stability of materials would benefit the screening of the glass formers for the industry of glassy materials. The present work aims at elucidating the factors that contribute to the glass formation by investigating medium-sized m…
The stabilities of three natural antioxidants, vitamin C (VC), (-)-epigallocatechin gallate (EGCG), and curcumin, in silk films were examined and mechanisms of stabilization were elucidated. The antioxidants were physically incorporated into three types of silk films: as-cast, dried from hydrogels, and methanol-treate…
The current work is to highlight the fundamental acumen about the molecular structure, photophysical and static first hyperpolarizability (β) of L-Histidinium 2-nitrobenzoate (LH2NB) organic molecule for the first time. Hartree–Fock (HF) and density functional theory (DFT) has been applied using different functional a…
We report here the effect of micro-environmental changes from biodegradable magnesium alloys on the activities of cells - osteoblasts, osteoclasts and macrophages - which play critical roles in each phase of the bone-regeneration process. Despite positive bone formation effects from several in vivo studies, minimal pr…
Tunable aliovalent doping is critical to controlling the optoelectronic properties of semiconductor nanocrystal systems. However, unintentional dopant-induced shape evolution and kinetically limited doping reactions in low-temperature nanocrystal syntheses make it difficult to independently control shape and incorpora…
The shear-induced coupled grain boundary motion plays an important role in the deformation of nanocrystalline (NC) materials. It has been known that the atomic structure of the grain boundary (GB) is not necessarily unique for a given set of misorientation and inclination of the boundary plane. However, the effect of…
Saturation transfer difference (STD) NMR spectroscopy is a powerful method for detecting and characterizing ligand-receptor interactions. In this study, the STD method was used to characterize the interactions of a Ti-binding peptide (TBP:RKLPDA) with TiO2 nanoparticles. The water peak in the NMR spectrum was selectiv…
Solutions of semiflexible polymers confined by repulsive planar walls are studied by density functional theory and molecular dynamics simulations, to clarify the competition between the chain alignment favored by the wall and the depletion caused by the monomer-wall repulsion. A coarse-grained bead-spring model with a…
The objective of this study was to investigate the effect of the alkali solution (Potassium and Sodium hydroxide), retting process (time and temperature), and type of leaf (fresh and dry) on the physical and chemical properties of fibers extracted from the Typha leaves. Tensile properties, optical microscope, CIE lab,…
Plasmonic materials are exciting candidates for driving photochemical reactions, as they couple strongly with light across a wide range of the electromagnetic spectrum and can dramatically impact the photophysical properties of proximal molecular species. Plasmons have been shown to drive a number of photochemical rea…
One of the main motivations for multiferroic researches is to explore distinctive magnetoelectric controls for conceptually novel electronic devices and information storage technologies. DyMnO3 possesses two major microscopic mechanisms for ferroelectricity generation, i.e., the inverse Dzyaloshinskii–Moriya interacti…
Titanium dioxide (TiO2) nanoparticles are important industrial nano-objects with wide applications, including as photocatalysts and sunscreen components. Recently, the phototoxicity of TiO2 nanoparticles has been a concern. However, phototoxicity caused by photocatalytic activity may differ between anatase and rutile…
Silver (Ag)-based nanoparticles are one type of highly effective antimicrobial widely used in medical devices, consumer products, and wound dressing. Although Ag(I) rather than Ag(0) is the active species in antibacterial processes, the use of Ag(I) as antibacterial materials is hindered by its instability toward ligh…
This short review discusses the concept of the electronic shell structure in the context of metal nanoclusters. Electronic shell structure is a natural consequence of quantization of fermionic states in a quantum confinement, where the symmetry of the confining potential creates energetically close-lying sets of state…
