Local interactions influence the fibrillation kinetics, structure and dynamics of Aβ(1–40) but leave the general fibril structure unchanged
A series of peptide mutants was studied to understand the influence of local physical interactions on the fibril formation mechanism of amyloid β (Aβ)(1-40). In the peptide variants, the well-known hydrophobic contact between residues phenylalanine 19 and leucine 34 was rationally modified. In single site mutations, r…
Effects of O 3 and H 2 O as oxygen sources on the atomic layer deposition of HfO 2 gate dielectrics at different deposition temperatures
Variations in the (a) growth rate and (b) film density, measured via the XRR of the HfO 2 films with O 3 and H 2 O oxidants as a function of T s (160–360 °C).
Organic semiconducting layers fabricated by self-metered slot-die coating for solution-processable organic light-emitting devices
Strip-patternable organic semiconducting thin layers are successfully deposited by self-metered slot-die coating to achieve bright and efficient solution-processable OLEDs.
CO 2 -driven vesicle to micelle regulation of amphiphilic copolymer: random versus block strategy
A vesicle to spherical micelle morphological regulation has been demonstrated with a random copolymer rather than its triblock counterpart.
Porous LiNi 0.5 Mn 1.5 O 4 sphere as 5 V cathode material for lithium ion batteries
A new type of microsized porous spherical LiNi 0.5 Mn 1.5 O 4 (LNMO-Air) cathode material for a lithium ion secondary battery has been synthesized by an impregnation method using highly reactive nanocupule MnO 2 spheres as the manganese source. These LNMO-Air spheres are aggregates of nanosized polyhedron particles wi…
Mechanical characterization of sisal reinforced cement mortar
This work aims at evaluating the mechanical behavior of sisal fiber reinforced cement mortar. The composite material was produced from a mixture of sand, cement, and water. Sisal fibers were added to the mixture in different lengths. Mechanical characterization of both the composite and the plain mortar was carried ou…
A magnetic field assisted self-assembly strategy towards strongly coupled Fe3O4 nanocrystal/rGO paper for high-performance lithium ion batteries
Quantum sized nanocrystals (NCs) have theoretically provided higher electrochemical activity for lithium ion batteries than their bulk counterparts due to their large surface area and short diffusion distance for Li+ ions. With ever-increasing interest in the development of next-generation, high-performance and flexib…
Vesicular self-assembly of a natural triterpenoid arjunolic acid in aqueous medium: study of entrapment properties and in situ generation of gel–gold nanoparticle hybrid material
Formation of vesicular gel and gel–gold nanoparticle hybrid material from arjunolic acid extractable from the saw-dust of Terminalia arjuna .
Fast and facile fabrication of porous polymer particles via thiol–ene suspension photopolymerization
The porous particles were fabricated via thiol–ene click chemistry within 5 minutes under mild conditions.
Significant roles of mesostructure and basic modifier for ordered mesoporous Ni/CaO–Al 2 O 3 catalyst towards CO 2 reforming of CH 4
The significant roles of mesostructure and basic modifier in improving the catalytic performance of dry reforming were investigated.
Recycling of Aluminum Chips by Hot Extrusion with Subsequent Cold Extrusion
In this paper, the direct conversion of AA6060 aluminum alloy machining chips into finished products by hot extrusion with subsequent cold extrusion is investigated. For hot extrusion, two different types of extrusion dies, a conventional flat-face die and an experimental die, are used. The experimental die combines t…
Extremely stable-color flexible white organic light-emitting diodes with efficiency exceeding 100 lm W −1
Flexible WOLEDs with extremely high efficiency and color-stability are realized via the extraordinary combination of mechanical, electrical and optical properties.
Proteome analysis of multidrug‐resistant, breast cancer–derived microparticles
Cancer multidrug resistance (MDR) occurs when cancer cells evade the cytotoxic actions of chemotherapeutics through the active efflux of drugs from within the cells. Our group have previously demonstrated that multidrug-resistant breast cancer cells spontaneously shed microparticles (MPs) and that these MPs can transf…
Towards a review of the EC Recommendation for a definition of the term "nanomaterial"; Part 1: Compilation of information concerning the experience with the definition
In October 2011 the European Commission (EC) published a Recommendation on the definition of nanomaterial (2011/696/EU). The purpose of this definition is to enable determination when a material should be considered a nanomaterial for regulatory purposes in the European Union. In view of the upcoming review of the cur…
Green synthesis of self assembled silver nanowire decorated reduced graphene oxide for efficient nitroarene reduction
We have developed a facile and green route to prepare reduced graphene oxide (rGO) from graphene oxide (GO) and decorated its surface edges with self assembled Ag Nanowires (Ag NWs). This was carried out by a novel approach using vegetable extract (Abelmoschus esculentus) as a reducing and stabilizing agent. Currently…
