Breast cancer nanotherapeutics is consistently progressing and being used to remove the various limitations of conventional method available for the diagnosis and treatment of breast cancer. Nanoparticles provide an interdisciplinary area for research in imaging, diagnosis, and targeting of breast cancer. With advance…
We discuss the synthesis of carbon nanotubes (CNTs) and graphene by catalytic chemical vapour deposition (CCVD) and plasma-enhanced CVD (PECVD), summarising the state-of-the-art understanding of mechanisms controlling their growth rate, chiral angle, number of layers (walls), diameter, length and quality (defects), be…
Reported here is a face-capped Fe(ii) molecular tetrahedron, [Fe(4)L(4)](BF(4))(8), . Single crystal X-ray diffraction at 153 and 293 K suggest spin crossover (SCO) and variable temperature magnetic susceptibility measurements confirm displays thermally driven SCO behaviour in the solid state and in dilute acetone sol…
We describe an environmentally friendly, top-down approach to the synthesis of Au89Fe11 nanoparticles (NPs). The plasmonic response of the gold moiety and the magnetism of the iron moiety coexist in the Au89Fe11 nanoalloy with strong modification compared to single element NPs, revealing a non-linear surface plasmon r…
The surfactant-like peptide (Ala)(6)(Arg) is found to self-assemble into 3 nm-thick sheets in aqueous solution. Scanning transmission electron microscopy measurements of mass per unit area indicate a layer structure based on antiparallel dimers. At higher concentration the sheets wrap into unprecedented ultrathin heli…
Biodegradable metal alloys emerge as a new class of biomaterials for tissue engineering and medical devices such as cardiovascular stents. Deploying biodegradable materials to fabricate stents not only obviates a second surgical intervention for implant removal but also circumvents the long-term foreign body effect of…
Uniform ultrathin titania/chitosan composite films were coated on the cellulose microfibril bundles of natural cellulose substance (common commercial filter paper) by a layer-by-layer self-assembly process. Relying on the strong chelating ability of chitosan for metal ions, silver ions were abundantly adsorbed on the…
In recent years, the bio-refining industry has developed a number of cyclic molecules with unique attributes derived from renewable carbohydrate feedstocks. Isosorbide is one such compound that has a distinctive fused bicyclic ring system that provides a scaffold for the development of novel bio-based resin systems. W…
In the present study, the effects of particle size (20 nm or 70 nm) and surface charge (negative or positive) on the pharmacokinetics, tissue distributions, and excretion of ZnO nanoparticles were examined following the administration of a single oral dose to rats. Pharmacokinetic profiles and biodistributions were no…
Although smectite clays have gained much interest in recent years as potential sustained local drug delivery vehicles, they have not been yet utilized or assessed as a local drug delivery device for treatment of periodontal disease. In this paper we showed that unique nanostructure and gel-formation ability of clay ho…
We report the synthesis of a dithienylethene–tetraphenylethene (DTE–TPE) conjugated photochromic fluorophore which simultaneously exhibits aggregation-induced emission and reversible fluorescence switching. Photochromic DTE–TPE turns cyan-blue after 5 s of UV irradiation and exhibits a strong green emission at 520–540…
Herein we describe a low-cost method for fabricating high-performance flexible supercapacitors based on 10 nm-scale MnO2 nanoparticles as active electrode materials. The as-fabricated supercapacitor possesses an electrochemical capacitance as high as 645 F g−1 at a discharge current density of 0.5 A g−1, as well as go…
Nanoparticles are considered as powerful tools in nanotechnological applications. Due to their unique physicochemical properties, their interactions with different biological systems have been shown. Nanomaterials have been successfully used as coating materials or treatment and diagnosis tools. Nevertheless, toxic ef…
The shear rheology of soft particle systems becomes complex at large density because crowding effects may induce a glass transition for Brownian particles or a jamming transition for non-Brownian systems. Here we successfully explore the hypothesis that the shear stress contributions from glass and jamming physics are…
A series of α-Al2O3-supported Ni catalysts with different Ni particle sizes (5–10, 10–20, and 20–35 nm) were prepared and applied in the CO methanation reaction for the production of synthetic natural gas (SNG). The catalytic tests showed that the Ni nanoparticles influenced the catalytic performance in the CO methana…
Nanoparticles (NPs) in the biological environment are exposed to a large variety and concentration of proteins. Proteins are known to adsorb in a 'corona' like structure on the surface of NPs. In this study, we focus on the effects of surface compositional and structural heterogeneity on protein adsorption by examinin…
Due to the extremely low surface tension of oils, the elaboration of superoleophobic surfaces implies the development of well-defined strategies to impede their tendency to spread. Usually, these strategies combine the presence of re-entrant structures (overhang, mushroom-like, T-like structures, etc.) with perfluorin…
The temporal growth of dynamic response during the aging of hectorite clay suspensions containing NaCl with different poly(ethylene glycol) (PEG) concentrations was measured. For each PEG concentration, the dynamic responses at different waiting times were shifted into a master curve against the rescaled frequency, wh…
In this study we investigated the effect of the nozzle type as one of the most important parts of the open-end rotor spinning system on yarn quality. 100% Urfa Region cotton was used for the production of yarns of 20 tex. Experimental studies were made on ten spinning units of a Rieter R1 machine. Five different ceram…
The properties of vortex yarn made from 100% polyester fibre with different fibre finenesses and spinning speeds were studied. Four different fibre finenesses (0.9, 1.1, 1.3 and 1.5 dtex) were used to produce yarns of 20 tex polyester vortex yarn with five different delivery speeds (320, 340, 360, 380 and 400 m/min),…
