“…A great effort has been made during past years in developing new polymerization methodologies to obtain MIP beads with proper physical characteristics (size, porosity, pore volume, surface area). Precipitation polymerization has been proposed as a simple and easy strategy for the formation of MIP beads quickly in excellent yield [19]. Thus, this study evaluates the polymer performance for selective recognition of atenolol which is made using bulk polymerization against precipitation polymerization to show the best polymerization methodologies with particular recognition and then applying it for atenolol recognition in plasma.…”

Silicon based composites are among the most promising negative electrodes for lithium ion battery applications due to their high theoretical capacities. One major drawback of silicon based anodes are their large volume changes during lithiation and delithiation. Although many efforts have been made in view of new binder materials and improved electrolytes, the resulting battery cell suffers from severe capacity fading at ambient or elevated temperatures, respectively. The strong reactivity with the electrolyte is considered to be responsible for the reduced cycle life at elevated temperatures. In this work we introduce silicon composite anodes with a novel composition based on a gellan gum binder material that show an improved cycling performance at ambient temperature and at 60 °C. To elucidate the influence of the binder material, we investigated the structure of the silicon based composite anodes in order to understand the nature of the interaction of the gellan gum based binder polymers with the silicon particles in comparison with a common CMC binder. Also the influence of the choice of binder on the interactions at the interface between electrode surface and electrolyte were studied. A combination of powerful techniques including solid state NMR, TEM and EELS, XPS as well as FTIR were applied.

“…Moreover, the DSC results showed a combination of thermal events in the nicotine-polymer binary mixture, which, in authors' opinion, can be associated with a preliminary indicative of drug-polymer compatibility. In another work, a method for synthesizing a MIP for an antistatic additive to polyolefins that has intra molecular H-bonding capability was studied, and with the help of DSC analysis, it was observed that one of the synthesis methods, the photochemical polymerization of the MIPs, was incomplete [53]. Additionally, the DSC analyses confirmed in the same work the presence of a crystalline phase by the appearance of a broad band in the DSC curves.…”

“…Another thermal technique, DSC, was successfully used in other recent studies [48][49][50][51][52][53][54]. In one of them [52], Ruela et al prepared some MIPs with possible application in nicotine delivery systems, and the DSC analysis showed that the polymer decomposes at *400°C, meaning that the MIPs have a high thermal stability.…”

Thermogravimetric analysis (TG), derivative thermogravimetry (DTG), differential scanning calorimetry (DSC), dynamic mechanical thermal analysis, simultaneous differential thermogravimetry (SDT) coupled with mass spectrometry (MS), and pyrolysis coupled with gas chromatography/mass spectrometry (Py-GC/MS) were used to characterize molecularly imprinted polymers (MIPs) obtained with two anti-cancerous template molecules, diosgenin and sclareol, imprinted in acrylonitrileacrylic acid copolymer matrices. First of all, TG analyses revealed a specific mass loss in the temperature range 220-300°C characteristic to diosgenin-MIPs, while for the sclareol-MIPs, the specific interval was 100-240°C. Further, the DSC analyses evidenced two major aspects: first, that the copolymer matrices have a single glass transition temperature (T g ), which confirms the random statistic copolymer structure, an essential characteristic of a homogenous MIP matrix; secondly, both templates influence the T g values of the MIPs, fact that is an additional proof of molecular imprinting. The SDT results confirmed the TG and DSC results and, additionally, proved that the system with higher acrylic acid content generates stronger template-matrix interactions via hydrogen, van der Waals, and other non-covalent forces, fact that appears as an increased thermal stability on the TG curve and a higher maximum for template decomposition on the DTG curve. The MS results evidenced that a single mass fragment, 139 ± 1 m/z, characteristic for the class of steroid sapogenines of which diosgenin belongs, is enough to prove, qualitatively and quantitatively, the molecular imprinting and the template elution. As global conclusion, the applied thermal analyses proved to be exceptional tools for analyzing these molecularly imprinted polymers.
