A poly(glycidyl methacrylate) (PGMA) synthesized by RAFT polymerization was spin-coated onto a silicon substrate to yield, after annealing and rinsing unreacted chains, covalently attached epoxy-containing PGMA pseudo-brushes. A tailor-made ω-amino-poly(ethylene) (Mn = 1040 g mol−1, PDI = 1.3) was then grafted in melt…
A fabrication of uniform nacre-like hierarchical nanostructures of faceted ZnO twin-crystals was established by a hydrothermal route using gelatin as the structure-directing agent, zinc nitrate hexahydrate as the Zn source, and hexamethylenetetramine to control alkalinity. Early stage growth of ZnO twin-crystals was i…
The combination of solvent annealing, surface reconstruction, and a tone-reversal etching procedure provides an attractive approach to utilize block copolymer (BCP) lithography to fabricate highly ordered and densely packed silicon oxide nano-dots on a surface. The obtained silicon oxide nano-dots feature an areal den…
Abstract A new generation of thermal shock resistant Al 2 O 3 ‐C refractories with approximately 30% less residual carbon and functionalized due to nanoscaled additives based on carbon nanotubes (CNTs) and alumina nanosheets (α‐Al 2 O 3 ) were developed and investigated after coking at 1000 and 1400 °C. With the aid o…
A silver(I)-linked decavanadate system has been synthesised, and characterised in both the solid-state and solution showing that two cluster units are held in a specific, dimeric arrangement wholly supported by cooperative hydrogen bonds, and ion-mobility mass spectrometry (IM-MS) was used to analyse the system yieldi…
I–III–VI2 semiconductor nanoparticles such as AgInS2 have been developed for cell imaging applications in recent years. However, there are few published works reporting the phase transfer (from hydrophobic to hydrophilic) of the AgInS2 nanoparticles for biomedical application purposes. In this work, we report the succ…
The continuous advance of the device performance in microelectronics requires the development of the lower dielectric constant (low-k) materials. We target the development of a next generation low-k material based on poly(p-phenylene benzobisoxazole) (PPBO) films due to their low k value, remarkable mechanical toughne…
Stem cell implantation is increasingly viewed as a promising strategy for the treatment of many diseases. A key aspect of stem cell therapies is the ability to distinguish the implanted cells from the host tissue cells and to understand their fate. Ex vivo labeling of the stem cells combined with non-invasive real tim…
In this paper, the surface stoichiometry, acid-base properties as well as the adsorption of xanthate at ZnS surfaces were studied by means of potentiometric titration, adsorption and solution speciation modeling. The surface proton binding site was determined by using Gran plot to evaluate the potentiometric titration…
Magnesium-based bioabsorbable cardiovascular stents have been developed to overcome limitations of permanent metallic stents, such as late stent thrombosis. During stent degradation, endothelial and smooth muscle cells will be exposed to locally high magnesium concentrations with yet unknown physiological consequences…
A unique Dy(III)-[2 × 2] grid assembled from long linear ligand represents the first example of its type showing slow relaxation of the magnetization.
The self-assembly propensity of peptides has been extensively utilized in recent years for the formation of supramolecular nanostructures. In particular, the self-assembly of peptides into fibrils and nanotubes makes them promising building blocks for electronic and electro-optic applications. However, the mechanisms…
You'll never walk alone: An auto-healing process of the first host-guest complex involving a polyoxometalate hybrid and a cyclodextrin is reported. Indeed, this inclusion complex allows the complete restoration of the anchored organic moiety released by a basic stress, a process otherwise not fully reversible.
We have fabricated the flexible photoelectrode by loading graphene sheets modified with CdSe QDs. A power conversion efficiency of ∼0.6% and an incident photon to current conversion efficiency of 17% have been achieved for this flexible photovoltaic cell based on a graphene-CdSe nanocomposite.
The present article reviews current situation on SiOx containing diamond like carbon (diamond like nanocomposite) films. The overview of different deposition methods and reagents used is presented; chemical composition of different diamond like nanocomposite films is described. Different models of structure of diamond…
Abstract A facile route for the large scale production of graphene oxide (GO) papers and their mechanical enhancement has been presented in this work. The novel paper-like GO made from individual GO sheets in aqueous suspension can be achieved in large scale by a simple drop casting method on hydrophobic substrates. S…
We report a new core-shell microcapsule system for the visual detection of mechanical damage. The core material, 1,3,5,7-cyclooctatetraene, is a conjugated cyclic olefin and a precursor to intensely colored polyacetylene. A combination of poly(urea-formaldehyde) and polyurethane is required to effectively encapsulate…
It is of great interest to study the shape effect on the catalytic activity of metal nanocrystals, which exposed different crystallographic facets upon adopting various shapes. The investigations on shape-dependent catalysis of supported metal nanocrystals need to be conducted over nanocrystals with well-defined shape…
Inorganic materials have become an increasingly researched topic due to their applications in many areas especially health care. One major problem with them is the effect that their surface coatings have on cells. The same coatings that are meant to increase biocompatibility can actually invoke cytotoxicity. This tuto…
Successful construction of a small-diameter bioartificial vascular graft remains a great challenge. This study reports on novel tissue engineering vascular grafts (TEVGs) constructed by endothelial progenitor cells and heparin-coated decellularized vessels (DV). The DVs were fabricated from canine carotid arteries wit…
