In contrast, the PEI-g-C3N4 NSs and LFs as Cr(VI) adsorbents followed the Langmuir isotherm model. Adsorption kinetic studies showed that the uptake of Cr(VI) through the PEI-g-C3N4 NSs@LFs was highly correlated with a pseudo-first-order model, suggesting that physisorption dominates the interaction of Cr(VI) and the PEI-g-C3N4 NSs@LFs. In real-life applications, the PEI-g-C3N4 NSs@LFs were used for the detoxification of the total chromium in the industrial effluent and sludge samples.Accurate thermochemistry estimation of polycyclic molecules is crucial for kinetic modeling of chemical processes that use renewable and alternative feedstocks. In kinetic model generators, molecular properties are estimated rapidly with group additivity, but this method is known to have limitations for polycyclic structures. This issue has been resolved in our work by combining a geometry-based molecular representation with a deep neural network trained on ab initio data. Each molecule is transformed into a probabilistic vector from its interatomic distances, bond angles, and dihedral angles. The model is tested on a small experimental dataset (200 molecules) from the literature, a new medium-sized set (4000 molecules) with both open-shell and closed-shell species, calculated at the CBS-QB3 level with empirical corrections, and a large G4MP2-level QM9-based dataset (40 000 molecules). Heat capacities between 298.15 and 2500 K are calculated in the medium set with an average deviation of about 1.5 J mol-1 K-1 and the standard entropy at 298.15 K is predicted with an average error below 4 J mol-1 K-1. The standard enthalpy of formation at 298.15 K has an average out-of-sample error below 4 kJ mol-1 on a QM9 training set size of around 15 000 molecules. By fitting NASA polynomials, the enthalpy of formation at higher temperatures can be calculated with the same accuracy as the standard enthalpy of formation. TTNPB clinical trial Uncertainty quantification by means of the ensemble standard deviation is included to indicate when molecules that are on the edge or outside of the application range of the model are evaluated.Metal-organic frameworks (MOFs) are an emerging class of porous materials composed of organic linkers and metal centers/clusters. The integration of MOFs onto the solid surface as thin films/coatings has spurred great interest, thanks to leveraging control over their morphology (such as size- and shape-regulated crystals) and orientation, flexible processability, and easy recyclability. These aspects, in synergy, promise a wide range of applications, including but not limited to gas/liquid separations, chemical sensing, and electronics. Dozens of innovative methods have been developed to manipulate MOFs on various solid substrates for academic studies and potential industrial applications. Among the developed deposition methods, the liquid-phase epitaxial layer-by-layer (LPE-LbL) method has demonstrated its merits over precise control of the thickness, roughness, homogeneity, and orientations, among others. Herein, we discuss the major developments of surface-mounted MOFs (SURMOFs) in LbL process optimization, summarizing the SURMOFs' performance in different applications, and put forward our perspective on the future of SURMOFs in terms of advances in the formulation, applications, and challenges. Finally, future prospects and challenges with respect to SURMOFs growth will be discussed, keeping the focus on their widening applications.It is confirmed that surfaces with specific microstructures could exhibit good superhydrophobic properties, and there are also a lot of conclusions about droplet hysteresis behavior. However, most of the research methods are based on two-dimensional ideal model and experimental observation at the macroscale. Further research needs to be conducted about the hysteresis behavior of droplets on the microstructure surface under three-dimensional conditions. In this paper, the influence of curvature variation of the liquid surface between pillars on the contact angle hysteresis (CAH) has been investigated. The simulation results were in good agreement with the experimental measurements. Analyses were conducted on the morphology change and force of the liquid surface between pillars, and an index was proposed to describe the degree of difficulty of liquid surface movement. It was revealed that a change in the direction of the surface tension at the three-phase interface caused by curvature variation of the liquid surface between pillars played an important role in the movement of the liquid surface. The greater the surface tension component in the normal direction of the liquid surface, the more likely it was for the liquid surface to advance or recede. The local curvature of the liquid surface increased or the angles between the pillars increased, and the effect of the CAH would be weakened.The nucleophilic substitution mechanism of enantioselective allylation of α-chloro glycinate catalyzed by squaramide organocatalysts was studied using density functional theory. Based on a comprehensive study of SN1 and SN2 pathways of a catalyst-free reaction, we found that the catalytic reaction slightly favors the SN1 mechanism, instead of the previously proposed SN2 mechanism. Further investigation of different leaving groups and nucleophiles revealed that this is not limited to the present reaction, and the SN1 mechanism might have been generally overlooked. For the squaramide-catalyzed reactions, the SN1 mechanism was predicted to be preferred. However, the rate-determining step of the SN1 pathway has changed from the chloride-leaving step to the C-C bond-formation step. Therefore, a first-order dependence on both substrates was predicted, in agreement with the observed second-order kinetics. Intriguingly, the lowest-energy enantioselective transition states (TSs) originate from different pathways; R-inducing TS corresponds to the SN1 pathway, while S-inducing TS corresponds to SN2. The calculated enantiomeric excesses of two squaramide catalysts agree well with the experimental values. Given the ubiquity of nucleophilic substitution reactions in chemistry and biology, we believe that our finding will inspire more studies that will lead to an improved mechanistic understanding of important chemical reactions, and it may even lead to better catalysts.
