Promotion of Self-Nucleation with Latent Form I Nuclei in Polybutene-1 and Its Copolymer

Wang, Zefan; Dong, Xia; Cavallo, Dario; Müller, Alejandro J.; Wang, Dujin

The formation of form I nuclei of polybutene-1 (PB-1) and its copolymer with polyethylene (PB1-ran-PE) has been studied by means of modified self-nucleation protocols. Even when the self-nucleation temperature was high enough and all form II crystals melt, recrystallization can be accelerated if the melt-crystallized sample was annealed at low…

Influence of adding a commercial phytosterol ester mixture on the ‘equilibrium’ crystallization behavior of palm oil

Daels, Eva; Goderis, Bart; Steen, Liselot; Foubert, Imogen

The objective of this study was to in depth investigate the ‘equilibrium’ state morphology and properties of crystals obtained after long-term isothermal crystallization and annealing of palm oil (PO) in the presence of different concentrations of phytosterol esters (PEs). A commercially available mixture of PEs was added to PO (0–100%…

Influence of γ-Lactones on Monolinolein/Water Bulk and Emulsified Mesophases

Tidu, Aurélien; Méducin, Fabienne; Faugère, Anne-Marie; Guillot, Samuel

The emulsification of two flavor compounds of the γ-lactone type with monolinolein liquid crystalline submicron particles is reported. The stabilization is ensured by the copolymer F127. γ-Nonalactone can be loaded in bicontinuous cubic monolinolein particles at a larger level (up to 20 wt %) than γ-decalactone (less than 15 wt…

Confinement Effects on the Crystallization of Poly(3-hydroxybutyrate)

Dai, Xiying; Li, Huihui; Ren, Zhongjie; Russell, Thomas P.; Yan, Shouke; Sun, Xiaoli

Poly(3-hydroxybutyrate) (PHB) is taken as an example to explore (i) whether the confined crystallization occurring in anodized aluminum oxide (AAO) nanopores is the same as that in ultrathin films, and (ii) whether the interfacial effect of curve surface is the same as flat surface. The crystallization behavior of PHB in AAO…

High efficiency non-fullerene organic solar cells without electron transporting layers enabled by Lewis base anion doping

Wang, Rong; Zhang, Dongyang; Xie, Shenkun; Wang, Jianqiu; Zheng, Zhong; Wei, Donghui; Sun, Xiaobo; Zhou, Huiqiong; Zhang, Yuan

Interfacial charge extraction and recombination play a critical role in photovoltaic characteristics of organic bulk heterojunction solar cells. Here we propose a methodology based on Lewis base n-doping with tetrabutylammonium acetate (TBAA) salts to boost charge extraction and resultant power conversion efficiencies (PCE) in OPVs with non-fullerene acceptors (NFA). Based…

Liquid Crystals of Self-Assembled DNA Bottlebrushes

Storm, Ingeborg M.; Kornreich, Micha; Hernandez-Garcia, Armando; Voets, Ilja K.; Beck, Roy; Cohen Stuart, Martien A.; Leermakers, Frans A. M.; de Vries, Renko

Early theories for bottlebrush polymers have suggested that the so-called main-chain stiffening effect caused by the presence of a dense corona of side chains along a central main chain should lead to an increased ratio of effective persistence length (lp,eff) over the effective thickness (Deff) and, hence, ultimately to lyotropic…
