In this work, we apply the recently developed frequency shift of nanoantennas (FRESA) technique to measure the Young’s modulus of thin mesoporous films at GHz frequencies as a function of porosity with local precision....

Bioinorganic canon states that active-site thiolate coordination promotes rapid electron transfer (ET) to and from type 1 copper proteins. In recent work, we have found that copper ET sites in proteins also can be constr...

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 ...

Sodium caseinate suspensions (Cas) are stabilized as submicelles in a dynamic system consisting of caseins α, β, and κ. Their use in the food industry is quite widespread because of their functional properties and nut...

It is shown that the anapolar interaction of the electrons of a molecule with an external uniform magnetic field B and a uniform curl C = × B′ determines different thermodynamic stabilization of the ground state for t...

Fluid transport on confined systems is a subject of theoretical and technological interest. For instance, remarkable high flow rates have been obtained in carbon nanochannels (CNs) which cannot be predicted by standard m...

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 classic Dukhin-Shilov theory for the thin double layer polarization of colloidal suspensions in binary electrolyte solutions was developed for symmetric electrolytes: equal counterion and co-ion valences. A rigorous ...

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...

Light absorption in gold nanoparticles leads to metal heating that induces photothermal reshaping because of atomic surface diffusion at temperatures well below the gold melting point. In this work, we perform time-resol...

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...

We have investigated the reaction of peroxynitrite with carbon dioxide in aqueoussolution by means of combined quantum-classical (QM-MM) molecular dynamics simulations.In our QM-MM scheme, the reactant was modeled using ...

Essential oils from six species of aromatic plants collected in the Catamarca Province of Argentina were evaluated for their chemical composition and repellent and insecticidal activities against beetles of the genus Car...

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...

Several studies have been published regarding the interaction between the spike protein of the novel coronavirus SARS-CoV-2 and ACE2 receptor in the host cells. In the presente work, we evaluated the in silico properties...

Cultures of hybridoma cells in bioreactors are commonly used to produce monoclonal antibodies. As an alternative to nonlinear model predictive control, which has recently been applied successfully to optimize the process...

We report an EPR study at X- and Q-bands of polycrystalline and single crystal samples of the mixed copper(II) complex with L-glutamic acid (glu) and 1,10-phenantroline (phen), [Cu(glu)(phen)(H2O)]+ NO3 −·2(H2O). The ...

A two-step synthesis of six-, seven-, eight-, and nine-member benzo-fused heterocycles in good to excellent yields is reported. The synthetic strategy involves the generation of a new intramolecular alpha-aryl ketone bon...
