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...

Pipeline networks are the dominant mode of conveying a wide variety of oil refined products from refineries to distribution terminals. Pipeline infrastructure usually comprises trunk lines serving high-volume, long-haul ...

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 development of dye-sensitized solar cells requires an in-depth understanding of the interfacial charge-transfer dynamics that take place between dye sensitizers and semiconductors. Here, we describe a prototype syste...

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 ...

The coalescence process of two nanoparticles to yield a core-shell structure is analyzed by a well-tempered metadynamics procedure. This methodology has been shown to be useful in understanding the present phenomenon in ...

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...

We find that for adsorbed terephthalic acid (TPA) molecules surface Sn alloying deactivates the Cu(001) surface by decoupling the adsorbed molecules from the substrate. This effect is investigated for the case of the 0.5...

Graphene nanoribbons with both armchair- and zigzag-shaped hydrogen-passivated edges (AGNR and ZGNR) have band gaps which depend on the width of the ribbon. In particular, a ZGNR has localized electronic states at the ed...

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...

High-power density output in enzymatic fuel cells is a key feature to reduce the size of self-powered implantable medical devices. Electron transfer mediated through redox polyelectrolytes allows the transport of electro...

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...

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...

Recently, DNA molecules have received great attention because of their potential applications in material science. One interesting example is the production of highly fluorescent and tunable DNA–Agn clusters with cytos...

Metal/polymer nanocomposites have attracted much attention in recent years due to their exceptional properties and wide range of potential applications. A key challenge to obtain these materials is to stabilize the metal...

Due to the impact of crude oil prices on refinery revenues, the petroleum industry has switched to processing lowcost crude oils. They are blended with high-quality crude oils to feed the crude distillation units (CDUs) ...

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...

Changing gel structure and immobilization conditions led to a significant improvement in the covalent multipoint attachment of chymotrypsin on chitosan. The use of sodium alginate, gelatin, or κ-carrageenan, activation ...

The current study provides a comprehensive look of the adsorption process of Candida rugosa lipase (CRL) on Ca2Fe2O5 iron oxide nanoparticles (NPs). Protein-support interactions were identified across a broad range of pH...

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...
