The ease of flammability of polymers represents a key issue that limits their applications in different advanced sectors. In this context, a reliable and effective solution regards the use of flame retardants, i.e., additives that are able to slow down (or even stop) the flame propagation and...
Calculations of electron density and electrostatic potential are carried out by the Dmol3 module, and the electrostatic potential distribution diagram shows that the maximum and minimum electrostatic potentials are distributed in different regions, thus predicting the reaction sites where electrophilic and nuc...
As indicated in the diagram, the energy level of TiO2 is 3.6 eV, while the Fermi energy of rGO exceeds 4.5 eV [76]. The Al serves as the bridge between the n-type (TiO2) and p-type (rGO) materials with a work function of 4.08 eV. The deposition of TiO2 on rGO formed a ...
The reverse water gas shift reaction can be considered as a promising route to mitigate global warming by converting CO2 into syngas in a large scale, while it is still challenging for non-Cu-based catalysts to break the trade-off between activity and selectivity. Here, the relatively high loa...
antarcticus sequences consistently formed a separate, highly supported branch for each protein. Similar phylogenetic placement was indicated for LipA and LipB nucleotide and protein sequences. The Trinidad strains also demonstrated lipolytic activity in culture, with an ability to utilize different ...
Such unique corrosion of Zn in PBS in a prolonged period can be described as following: in the initial stage, Zn is oxidized to zinc ions in anodic spots following Eq. (6). The electrons generated from anodic reaction are consumed by the corresponding cathodic reaction by means of reduction...
Concerning humic substances, as stated by Bolto (Citation1995), at pH 5–6, various aluminium humates may be formed through the polynuclear aluminium species, produced during the following stoichiometric reaction: 5RCOO−+Al13OH345+→RCOO5Al13OH34↓(2) The more explicit mechanism for alumin...
reaction vessel at the rates which kept the reaction pH at 7.5 ± 0.2. In this way, the reaction pH was maintained constant from the very beginning of the coprecipitation process. When the two solutions mixed with each other, a precipitate immediately formed and an opaque suspension was ...
β-elimination to propylene both in the presence and absence of the produced water molecule at the catalyst surface. The free energy profiles for the overall reaction on the two sites are compared in Fig.4c. Two observations are in order: (a) dehydration on the –OH site requires 0.3 ...
In order for sustainable nanomaterials such as cellulose nanocrystals (CNCs) to be utilized in industrial applications, a large-scale production capacity for CNCs must exist. Currently the only CNCs available commercially in kilogram scale are obtained f
