Steady-state and time-resolved emission spectroscopy (TRES) of the medium-sensitive probes 4-aminophthalimide (4-AP) and 6-propionyl-2-(dimethylamino)naphthalene (Prodan) were performed at 77 and 298 K in vacuum-sealed t...

Graphene layers are known to stack in two stable configurations, namely, ABA or ABC stacking, with drastically distinct electronic properties. Unlike the ABA stacking, little has been done to experimentally investigate t...

The increasing complexity of composite materials structured on the nanometer scale requires highly sensitive analytical tools for nanoscale chemical identification, ideally in three dimensions. While infrared near-field ...

We report on a reversible structural phase transition of a two-dimensional system that can be locally induced by an external electric field. Two different structural configurations may coexist within a CO monolayer on Cu...

C4-Symmetrical dirhodium(II) tetracarboxylates are highly efficient catalysts for the asymmetric intermolecular aziridination of substituted alkenes with sulfamates. The reaction proceeds with high levels of efficiency a...

Carbon nanodots (CNDs) undergo electron transfer in different scenarios. Previous studies have mainly focused on the electron-accepting features of CNDs in covalently linked donor-acceptor nanoconjugates. In view of this...

Using molecular dynamics experiments, we analyze the association of "Janus" 6-amino-6-deoxy-2O-carboxymethyl-β-cyclodextrins (JCD) in aqueous solutions. In JCD dimers, the free energy associated with the primary-rim-sec...

The adsorption of commercial trypsin (Try) onto epichlorohydrin cross-linked alginate–guar gum matrix has been studied at equilibrium in batch and in fixed bed column. Experiments were conducted to study the effect of ...

We investigate the drying dynamics of mesoporous silicon bilayers with controlled pore geometries during ethanol evaporation. Using Reflective Interferometric Fourier Transform Spectroscopy (RIFTS), we track the evolutio...

The influence of the solvent (water, acetone, and ethanol) used during alumina impregnation on the properties of Pt/Al2O3 and Pt−Sn/Al2O3 catalysts was studied. Catalysts were characterized by H2 chemisorption, TEM, te...

The reactivity of a heavy model molecule (quinolin-65, named Q65, a 2,3,7,8-dibenzopyrene derivative) over two different equilibrium fluidized catalytic cracking catalysts of the conventional and resid types was studied...

An interparticle system has been devised, allowing airborne singlet oxygen to transfer between particle surfaces. Singlet oxygen is photogenerated on a sensitizer particle, where it then travels through air to a second p...

Molecular iodine was identified as an efficient catalyst for the cycloisomerization of conjugated dienals to substituted 2-cyclopentenones. DFT calculations suggested an unexpected concerted character for this cyclizatio...

The knowledge and the ability to describe the phase equilibrium behavior of systems composed of transesterification products are very important in the optimization of biodiesel production and purification process. In thi...

The coherent manipulation of acoustic waves on the nanoscale usually requires multilayers with thicknesses and interface roughness defined down to the atomic monolayer. This results in expensive devices with predetermine...

In the present paper, the performance of monolithic catalysts obtained from a catalytic converter was analyzed in the partial hydrogenation of sunflower oil. The monoliths were reimpregnated with palladium and installed ...

Metal–organic frameworks (MOFs) have emerged as promising materials for atmospheric water harvesting (AWH). Large-pore MOFs provide high water capacity, but their significant hysteresis between sorption and desorption ...

Six new uranyl hybrid materials have been synthesized solvothermally utilizing the ligands 2,2′-bipyridine-3,3′-dicarboxylic acid (H2L) and 2,2′:6′,2′′-terpyridine (TPY). The six compounds are classified as e...

The phase equilibria of binary CO2 + n-alkane mixtures have been studied by an important number of authors, both experimentally and using different types of thermodynamic models. Modeling studies of the phase behavior of...

The oxidation of proteins and, in particular, of tryptophan (Trp) residues leads to chemical modifications that can affect structure and function. The oxidative damage to proteins in photochemical processes is relevant i...

We propose a general nucleation and growth model that can explain the mechanism of the formation of CoPt 3/Au, FePt/Au, and Pt/Au nanodumbbells. Thus, we found that the nucleation event occurs as a result of reduction of...

We describe polymer diffusion and its temperature dependence in poly(vinyl acetate-co-dibutyl maleate) [P(VAc-DBM)] latex films prepared from 4:1 w/w ratio of VAc:DBM. Two sets of polymers were investigated: one set cont...
