George, Gejo; Sisupal, Suja Bhargavan; Tomy, Teenu; Kumaran, Alaganandam; Vadivelu, Prabha; Suvekbala, Vemparthan; Sivaram, Swaminathan; Ragupathy, Lakshminarayanan

The success of developing graphene based biomaterials depends on its ease of synthesis, use of environmentally benign methods and low toxicity of the chemicals involved as well as biocompatibility of the final products/devices. We report, herein, a simple, scalable and safe method to produce defect free few layers graphene using…

High sensitivity organic inorganic hybrid X-ray detectors with direct transduction and broadband response

Thirimanne, H. M.; Jayawardena, K. D. G. I.; Parnell, A. J.; Bandara, R. M. I.; Karalasingam, A.; Pani, S.; Huerdler, J. E.; Lidzey, D. G.; Tedde, S. F.; Nisbet, A.; Mills, C. A.; Silva, S. R. P.

X-ray detectors based on low-cost organic semiconductors have inherently low detector sensitivity due to poor X-ray to charge conversion and charge collection. Here, the authors demonstrate a flexible, high-sensitivity X-ray detector based on an organic bulk heterojunction-nanoparticle…

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…

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…

Morphological metamorphosis of magnetic nanoparticles due to the presence of rare earth atoms in the spinel structure: From spheres to cubes

Parekh, Kinnari; Espinosa, Daniel H. G.; Reis, Dennys; de Oliveira, Cristiano L. P.; Wlysses, Wagner; Figueiredo Neto, Antônio Martins

We report the effect of replacement of 5% of the Fe atoms by Ho during the synthesis of magnetic nanoparticles (MNPs) in the original colloidal system composed of Mn, Zn, Fe, O. Without the presence of Ho the MNPs are spherical and, when the Ho is included in the synthesis…

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%…

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…
Metal organic framework laden poly(ethylene oxide) based composite electrolytes for all-solid-state Li-S and Li-metal polymer batteries

In this work, the possibility of employing aluminium terephthalic acid metal organic framework (Al-TPA-MOF)-laden composite polymer membranes as electrolyte for all-solid-state lithium-sulfur (Li-S) and lithium-metal (Li-metal) polymer batteries is explored. The prepared composite polymer electrolytes (CPEs) based on a poly(ethylene oxide) (PEO) network with lithium…

Polyurethane/carbon fiber composite tubular electrode featuring three-dimensional interpenetrating conductive network

Zhang, Kailin; Li, Yijun; Zhou, Huan; Nie, Min; Wang, Qi; Hua, Zhengkun

Flexible and stretchable electronics are important components in medical implantation, wearable durable devices and so on. However, conductive stability often conflicts with the mechanical stretchability in terms of decreased conductivity from the deformation. Here, we proposed a facile and effective strategy to construct a three-dimensional interpenetrating alignment configuration of conductive…

Antibacterial properties of human beta defensin-3 derivative: CHRG01

Arora, A.; Majhi, S.; Mishra, A.

Antibiotic resistance in bacteria is a major health concern. Antimicrobial peptides (AMPs) are a class of peptides that are efficient in killing most microbes yet development of resistance to AMPs is rare. However, complex secondary and tertiary structures and difficulties in isolating AMPs have limited their use as antibiotics. It…
