A cocrystal strategy for the precipitation of liquid 2,3-dimethyl pyrazine with hydroxyl substituted benzoic acid and a Hirshfeld surfaces analysis of them
We here report the cocrystal strategy for the precipitation of liquid 2,3-dimethyl pyrazine (2,3-DMP) with the hydroxyl substituted benzoic acids: salicylic acid (SA), m-hydroxybenzoic acid (MHBA) and p-hydroxybenzoic acid (PHBA) under identical conditions, and obtained three cocrystals (cocrystal 1–3), respectively. Their crystal structures were characterized by single-crystal X-ray diffraction,...

Two Novel Salts of Tris(hydroxymethyl)aminomethane (THAM):Synthesis, Crystal Structure, Thermal and Hirshfeld Surfaces Analysis
The crystals of two organic salts of tris(hydroxymethyl)aminomethane (THAM) with p-hy-droxybenzoic acid (PHBA) and salicylic acid (SA) were obtained. Their crystal structures were characterized by single-crystal X-ray diffraction, IR spectra, differential scanning calorimetry, thermogravimetric analyses and hot stage microscopy. Wherein, 1 forms a 1:1 (THAM:PHBA) salt, and 2 forms a 2:2:1 (THAM:SA...

QSPR analysis for melting point of fatty acids using genetic algorithm based multiple linear regression (GA-MLR)
A quantitative structure–property relationship (QSPR) study was performed to correlate the melting point of fatty acids with their molecular structures. The entire set of 62 fatty acids was divided into a training set of 48 acids and a test set of 14 acids according to the DUPLEX algorithm. An extended set of molecular descriptors was calculated to represent the molecular structures by DRAGO...

Thermal degradation analysis and XRD characterisation of fibre-forming synthetic polypropylene containing nanoclay
Flammability of synthetic fibres is significantly worse than that of bulk polymers because of the high surface area to volume ratio and the low
tolerance to high filler loadings in the fibre production process. Introducing nanocomposite structures has the potential to enhance the char
formation at relatively low loadings of nanoparticulate fillers and hence can reduce the flammability of synthe...

Computational analysis of effect of modification on the interfacial characteristics of a carbon nanotube–polyethylene composite system
In this study, the non-covalent association of single-walled nanotube (SWNT) with polyethylene (PE) molecule and the influence of sidewall modification on the interfacial bonding between the SWNTs and polymer were investigated using molecularmechanics (MM) andmolecular dynamics (MD) simulations.
The model of interaction between the initially separated PE and SWNT fragments, which can be either wr...

Strategies for the analysis of poly(methacrylic acid) by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry.
We evaluated several aq.-based sample prepn. protocols for the anal. of poly(methacrylic acid) (PMAA) by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOFMS). The sample contained a pentaerythritol tetra(3-mercaptopropionate) end-group, and was characterized in pos. and neg. ion modes using 2,5-dihydroxybenzoic acid (DHB) and 2,4,6-trihydroxyacetophenone...
