Abstract
In this work, pectin was employed as a coating material to fabricate zein/whey protein isolate (WPI)/pectin complex nanoparticles via a pH-adjusted and heat-induced electrostatic adsorption process for potential oral administration applications of curcumin. Factors such as the order of raw material addition, heating temperature and pH, and zein concentration were comprehensively examined. In addition to electrostatic interactions, Fourier transform infrared and fluorescence spectroscopy indicated that hydrophobic interactions and hydrogen bonds were also involved in the development of complex nanoparticles. The complex nanoparticles obtained not only improved the antioxidant activity of curcumin in aqueous phase, but also contributed to its controlled release under gastrointestinal conditions. Our findings revealed that the heating pH and adding sequence of raw materials had a notable impact on the properties of complex nanoparticles, and that pectin coating had an exceptional stabilizing effect on complex nanoparticles under gastrointestinal circumstances. This study provides novel insights and perspectives for the preparation of polysaccharide-protein complex nanoparticles, signifying the potential use of zein/WPI/pectin complex nanoparticles as delivery vehicles in the functional food and pharmaceutical industries.

Abstract
Shear thickening fluids have found many applications in energy damping materials such as sports guards and liquid body armors. Therefore, an additive which could tailor the dilatant properties of such fluids without significantly affecting other properties, especially zero shear viscosity, could significantly increase the versatility of protective materials based on shear thickening fluids. In this paper, poly(propylene glycols) (PPGs) diacetates are investigated as dilatant effect enhancers for nano-silica dispersions in poly(propylene glycols). The influence of the modifiers on rheological properties of the dispersion is studied and discussed. Additionally, FTIR and rheological properties measurements are conducted in order to determine relative interactions strength between hydroxyl groups of PPGs and silica and carbonyl groups of PPG diacetates. Our findings suggest that the relative attractive interaction strength in studied systems can be arranged in the following order: COCO < COOH < OHOH. Therefore, the addition of PPG diacetate hinders the attractive interactions between liquid and solid. We report that the addition of diacetates can lead both to enhancement and deterioration of dilatant effect depending on the concentration of the modifier and its chain length. Based on conducted measurements and literature data, mechanism explaining that phenomenon is suggested. As a result, we propose an easy to make and cheap dilatant effect enhancer for widely used shear thickening fluids which, when used in small amounts (1-2.5%), raises the viscosity jump drastically. Additionally, the presence of the modifier does not significantly affect the zero shear viscosity of the shear thickening fluid.

Abstract
![]()
The
development of high-performance electrocatalytic systems for the controlled
reduction of CO2 to value-added chemicals is a key goal
in emerging renewable energy technologies. The lack of selective and
scalable catalysts in aqueous solution currently hampers the implementation
of such a process. Here, the assembly of a [MnBr(2,2′-bipyridine)(CO)3] complex anchored to a carbon nanotube electrode via a pyrene
unit is reported. Immobilization of the molecular catalyst allows
electrocatalytic reduction of CO2 under fully aqueous conditions
with a catalytic onset overpotential of η = 360 mV, and controlled
potential electrolysis generated more than 1000 turnovers at η
= 550 mV. The product selectivity can be tuned by alteration of the
catalyst loading on the nanotube surface. CO was observed as the main
product at high catalyst loadings, whereas formate was the dominant
CO2 reduction product at low catalyst loadings. Using UV–vis
and surface-sensitive IR spectroelectrochemical techniques, two different
intermediates were identified as responsible for the change in selectivity
of the heterogenized Mn catalyst. The formation of a dimeric Mn0 species at higher surface loading was shown to preferentially
lead to CO formation, whereas at lower surface loading the electrochemical
generation of a monomeric Mn-hydride is suggested to greatly enhance
the production of formate. These results emphasize the advantages
of integrating molecular catalysts onto electrode surfaces for enhancing
catalytic activity while allowing excellent control and a deeper understanding
of the catalytic mechanisms.

Abstract
The effects of different formulations and processes on inducing and maintaining the supersaturation of ternary solid dispersions of ezetimibe (EZ) in two biorelevant media fasted-state simulated intestinal fluid (FaSSIF) and fasted-state simulated gastric fluid (FaSSGF) at different temperatures (25 °C and 37 °C) were investigated in this work. Ternary solid dispersions of EZ were prepared by adding polymer PVP-K30 and surfactant poloxamer 188 using melt-quenching and spray-drying methods. The resulting solid dispersions were characterized using scanning electron microscopy, differential scanning calorimetry (DSC), modulated DSC, powder X-ray diffraction and Fourier transformation infrared spectroscopy. The dissolution of all the ternary solid dispersions was tested in vitro under non-sink conditions. All the prepared solid dispersions were amorphous in nature. In FaSSIF at 25 °C, the melt-quenched (MQ) solid dispersions of EZ were more soluble than the spray-dried (SD) solid dispersions and supersaturation was maintained. However, at 37 °C, rapid and variable precipitation behavior was observed for all the MQ and SD formulations. In FaSSGF, the melting method resulted in better solubility than the spray-drying method at both temperatures. Ternary solid dispersions show potential for improving solubility and supersaturation. However, powder dissolution experiments of these solid dispersions of EZ at 25 °C may not predict the supersaturation behavior at physiologically relevant temperatures.

Abstract
Cocrystals of tenoxicam, a non-steroidal anti-inflammatory drug, are screened, prepared, and characterized in this study. Nine tenoxicam cocrystals were identified using solvent-drop grinding (SDG) techniques. Structural characterization was performed using powder X-ray diffraction (PXRD), differential scanning calorimetry, and multinuclear solid-state NMR (SSNMR). Thermal analysis, PXRD, and 1D SSNMR are used to detect solvates and phase mixtures encountered in SDG cocrystal screening. 2D SSNMR methods are then used to confirm cocrystal formation and determine structural aspects for selected cocrystals formed with saccharin, salicylic acid, succinic acid, and glycolic acid in comparison to Forms I and III of tenoxicam. Molecular association is demonstrated using cross-polarization heteronuclear dipolar correlation (CP-HETCOR) methods involving (1)H and (13)C nuclei. Short-range (1)H-(13)C CP-HETCOR and (1)H-(1)H double-quantum interactions between atoms of interest, including those engaged in hydrogen bonding, are used to reveal local aspects of the cocrystal structure. (15)N SSNMR is used to assess ionization state and the potential for zwitterionization in the selected cocrystals. The tenoxicam saccharin cocrystal was found to be similar in structure to a previously-reported cocrystal of piroxicam and saccharin. The four selected cocrystals yielded intrinsic dissolution rates that were similar or reduced relative to tenoxicam Form III.

Abstract
We encountered a unique phenomenon of reaction velocity reversal during the silylation between mixed simple alcohols (A; AOH) and alpha- or beta-hydroxyketones (B; BOH). The present reaction system using anilinosilanes 1a [PhNH(TMS)] (TMS-A) and 1b [PhNH(TES)] (TES-A) with the catalytic TBAF (0.02 equiv) reagent showed that the order of silylation-velocity between the independent system and the mixed system was distinctively reversed [nu(A) > nu(B) approximately nu(B(mix)) > nu(A(mix))]. A total of seven examples indicate its high generality: AOH = linalool, 3-octanol; BOH = valeroin, benzoin, 5-hydroxy-4-methyl-3-undecanone. Time-dependent IR spectroscopy analysis rationally supported this speculation.

Abstract
Five polymorphic forms of tranilast were characterized by thermal, diffractometric, and spectroscopic techniques. The crystal structures of the most stable anhydrous form (Form I), a chloroform solvate, and a dichloromethane solvate were determined from single-crystal X-ray analysis. Two additional anhydrous forms of tranilast (Forms II and III) were also studied, but were not amenable to SCXRD. All five forms were also analyzed using solid-state nuclear magnetic resonance, Fourier transform infrared, and Fourier transform-Raman spectroscopy, and thermal methods. From the trends observed in the crystal structures and the spectral data, some conclusions can be made about hydrogen bonding, molecular conformation, and crystal packing differences in the polymorphs and solvates. Form II was found to be a spectroscopically distinctive polymorph that is probably missing an important intramolecular hydrogen bond coupled with a conformational change. In contrast, Form III was found to be more similar to the crystallographically characterized forms, and is more likely a packing and hydrogen-bonding polymorph with a weakened intermolecular hydrogen-bonding interaction relative to the other forms. From a pharmaceutical development perspective, it is shown that although the anhydrous forms of tranilast have similar thermal properties, they can be reliably distinguished by spectroscopic methods.
