A highly efficient acido-triggered reversible luminescent and nonlinear optical switch based on 5-π-delocalized-donor-1,3-di(2-pyridyl)benzenes is presented.
Thanks to major advances in laser technologies, recent investigations of the ultrafast coupling of nuclear and electronic degrees of freedom (vibronic coupling) have revealed that such coupling plays a crucial role in a wide range of photoinduced reactions in condensed phase supramolecular systems. This paper investig…
To study the relationship between dynamics and structure in a glass-forming liquid, we introduce a purely geometric criterion for locally mobile particles in a dense hard-sphere fluid: namely, "T1-active" particles, which can gain or lose at least one Voronoi neighbor by moving within their free volume with other part…
Sequentially deposited CuS and PbS layers on the FTO substrate as a counter electrode in quantum dot sensitized solar cells.
Although light-induced magnetostructural switching in copper(II)-nitroxide molecular magnets Cu(hfac)2L(R) has been known for several years, structural characterization of metastable photoinduced states has not yet been accomplished due to significant technical demands. In this work we apply, for the first time, varia…
Cu-SSZ-13 catalysts were treated with ammonium hexafluorosilicate (AHFS) to improve their hydrothermal stabilities.
We demonstrate a straightforward nonbiomolecular approach for self-assembly of binary NP planet-satellite superstructures, which display remarkable colloidal and structural stability under variations in temperature, pH, ionic strength and solvent. The readily scalable process produces highly homogeneous samples and is…
The aim of this study was to obtain new films based on collagen-chitosan with and without silver for biomedical applications. Membranes with a thin transparent elastic structure were obtained and after immersion in silver nitrate new membranes with silver have been elaborated and their physicochemical properties were…
Bone-cuboid (a and b), spindle (c and d) and rhombic (e and f) TiO <sub>2</sub> nanocrystals are all self-assembled into horizontal and vertical ordered two-dimensional superlattices.
Abstract—We present an extremely sub-wavelength negative index metamaterial structure operating at radio frequency. The unit cell of the metamaterial consists of planar spiral and meandering wire structures separated by dielectric substrate. The ratio of the free space wavelength to unit cell size in the propagation d…
Natural gel pectin is transformen into interconnected, N-doped, ordered and Interconnected 1D nano-carbon threads upon high temperature pyrolysis inside SBA-15.
The growth kinetics of single-walled carbon nanotubes (SWCNTs) in a low-temperature, low-pressure reactive plasma is investigated using a multiscale numerical simulation, including the plasma sheath and surface diffusion modules. The plasma-related effects on the characteristics of SWCNT growth are studied. It is foun…
Doping has become an effective way to tune the catalytic properties of nanostructured carbon catalysts. Taking C-H activation as an example, first-principles calculations propose that the relative energy level and the BEP rule might be applicable to explain the observed doping effects. Moreover, boron doping is propos…
Dielectric permittivity measurements were performed on water solutions of propylene glycol (PG) and propylene glycol monomethyl ether (PGME) confined in 21 Å pores of the silica matrix MCM-41 C10 in wide frequency (10(-2)-10(6) Hz) and temperature (130-250 K) ranges. The aim was to elucidate how the formation of large…
Photo-responsive self-assemblies based on bio-inspired bolaamphiphiles with oligo (ethylene oxide) hydrophilic outer segments and a hydrophobic inner segment with thymine were investigated. The morphology of the self-assemblies transformed from ribbon-like structures to spherical structures in water by UV irradiation…
We propose a novel approach to obtain conducting polymer nanoparticles with high electrochemical activity and a narrow size distribution. The method - templateless and seedless - uses polyacrylate microspheres to deliver the monomer for the polymerization reaction. Thus the obtained nanostructures have an active - unb…
The water soluble tris-aqua complex [Gd(dhqN-SO3)(H2O)3](3-) based on a hexadentate hydroxyquinoline ligand shows high thermodynamic stability and high relaxivity (12.54 mM(-1) s(-1) at 1.2 T). Its non-covalent confinement in 25 nm silica nanoparticles prevents transmetallation and endogenous anion binding and leads t…
Multicomponent particles have emerged in recent years as new compartmentalized colloids with two sides of different chemistry or polarity that have opened up a wide field of unique applications in medicine, physics and chemistry.
The TSV filling using the dialyl-amine and the Br − and Cl − halogen ions to a copper electrodeposition bath is reported. The TSV bottom acceleration and TSV outside inhibition have been measured by an electrochemical method using the rotating disk electrode and numerical computation of the fluid dynamics. A perfect T…
Single walled carbon nanotubes as free-radical scavengers and novel drug carriers are important in the drug delivery systems because of their high selectivity to target for cancer cells. Quercetin, one of Flavonoids derivatives, has effective chemopreventive and anticancer properties. This study was done to investigat…
