Sulfate dodecyl sodium-induced stability of a model intrinsically disordered protein, bovine casein
With well-known nutritional properties, casein contributes to about 80% of protein content in milk and has been classified as highly intrinsically disordered protein (IDP). In this paper, the sulfate dodecyl sodium (SDS)-induced conformational changes of bovine casein were studied by multi-techniques. Isothermal titration calorimetry (ITC) and differential scanning calorimetry (DSC)…
Sugar-cane bagasse derived cellulose enhances performance of polylactide and polydioxanone electrospun scaffold for tissue engineering
Ramphul, Honita; Bhaw-Luximon, Archana; Jhurry, Dhanjay
Bagasse is a waste product of sugar extraction from sugar-cane with approximately 30% cellulose content. Cellulose was successfully extracted from sugar-cane bagasse using a modified mercerization-bleaching approach with a 40% yield. Extracted cellulose was converted to cellulose acetate for enhanced electrospinnability and blended with poly-l-Lactide or polydioxanone before solution…
Studies on blends of natural rubber and butadiene rubber containing silica – Organomodified kaolin hybrid filler systems
Raji Vijay, V.; Anitha, A. M.; Ravindranatha Menon, A. R.
Hybrid filler systems consisting of precipitated silica and kaolin modified with a sodium salt of rubber seed oil (SRSO) were studied in blends of natural rubber (NR) and polybutadiene rubber (BR). Substitution of 5–10 phr (parts per hundred rubber) of silica with SRSO modified kaolin imparted lower Mooney viscosity and higher…
Structure, transport and photoconductance of PbS quantum dot monolayers functionalized with a copper phthalocyanine derivative
André, A.; Theurer, C.; Lauth, J.; Maiti, S.; Hodas, M.; Khoshkhoo, M. Samadi; Kinge, S.; Meixner, A. J.; Schreiber, F.; Siebbeles, L. D. A.; Braun, K.; Scheele, M.
We simultaneously surface-functionalize PbS nanocrystals with Cu 4,4′,4′′,4′′′-tetraaminophthalocyanine and assemble this hybrid material into macroscopic monolayers. Electron microscopy and X-ray scattering reveal a granular mesocrystalline structure with strong coherence between the atomic lattice and the superlattice of nanocrystals within each domain. Terahertz spectroscopy and field-effect…
Structure evolution of polyamide (11)’s crystalline phase under uniaxial stretching and increasing temperature
Xiao, Xueliang; Cai, Ziqing; Qian, Kun
Thermal processing of polyamide influences the internal crystalline structure and thereafter the post product mechanical performance. In this article, the crystalline transition of polyamide-11 (PA11) plate under uniaxial stretching and increasing temperature was investigated systematically using in-situ synchrotron X-ray technique. It was discovered that the lamellar slippage, fragmentation and…
Structure and crystallization behaviour of syndiotactic polystyrene/layered double hydroxide nanocomposites
Nagendra, Baku; Das, Amit; Leuteritz, Andreas; Gowd, E. Bhoje
Highly dispersed polymer nanocomposites were prepared by solution blending method. The influence of surfactant free LDH particles on the crystallization behavior and flame retardant properties of syndiotactic polystyrene are…
Structural Transitions in Solution-Cast Films of a New AABB Type Thiophene Copolymer
Chen, Haiming; Liu, Guoming; Qin, Yunpeng; Müller, Alejandro J.; Hou, Jianhui; Wang, Dujin
The structural transitions in solution-cast film of poly (PDCBT) copolymer have been systematically studied by a combination of differential scanning calorimetry (DSC), dynamic mechanical analysis (DMA), in situ Fourier transform infrared spectroscopy (FTIR), UV–vis spectroscopy, and in situ wide-angle X-ray…
Structural Phase Transitions of Syndiotactic Polystyrene upon the Guest Extraction Process
Shaiju, P.; Gowd, Erathimmanna Bhoje
In this work, the effects of initial morphology/crystalline form and the guest molecules used for the preparation of syndiotactic polystyrene (sPS) co-crystals, on the structural phase transitions of sPS upon the guest extraction process were systematically investigated. For that purpose, samples having two different initial morphologies such as amorphous and…
Structural evolution from shish-kebab to fibrillar crystals during hot-stretching process of gel spinning ultra-high molecular weight polyethylene fibers obtained from low concentration solution
Wang, Zongbao; An, Minfang; Xu, Haojun; Lv, You; Tian, Feng; Gu, Qun
The pre-stretched gel-spinning ultra-high molecular weight polyethylene fibers with low concentration solution obtained from industrial production line were used to study the structural transition from shish-kebab to fibrillar crystals during hot-stretching process via in-situ small-angle X-ray scattering, wide-angle X-ray diffraction measurements, and scanning electron microscopy. With the…
