Many acronyms are used in the literature for describing different kinds of amorphous ice, mainly because many different preparation routes and many different sample histories need to be distinguished. We here introduce these amorphous ices and discuss the question of how many of these forms are of relevance in the con…
Oil contaminated water is a common problem in the world, thus to effectively separate water and oil is an urgent task for us to resolve. By control of surface wettability of a solid substrate, both superhydrophobicity and superoleophilicity on a film can be realized, which is necessary for water and oil separation. He…
This paper reviews the progress made recently in synthesis and applications of spherical silica micro/nanomaterials with multilevel (hierarchical) structures. The spherical silica micro/nanomaterials with hierarchical structures are classified into four main structural categories that include (1) hollow mesoporous sph…
Here we report a novel peptide–polysaccharide hybrid hydrogel as a potential carrier for sustained delivery of hydrophobic drugs. The hybrid hydrogel composed of Fmoc-diphenylalanine (Fmoc-FF) peptide and konjac glucomannan (KGM) was prepared through molecular self-assembly of Fmoc-FF in the KGM solution. The physicch…
We investigated photoelectrodes based on TiO(2)-polyheptazine hybrid materials. Since both TiO(2) and polyheptazine are extremely chemically stable, these materials are highly promising candidates for fabrication of photoanodes for water photooxidation. The properties of the hybrids were experimentally determined by a…
In this paper, we will thoroughly review a novel and versatile self-formation phenomenon that can be exploited to target porous hierarchies of materials without need of any external templates only on the basis of the chemistry of metal alkoxides and alkylmetals. These hierarchically porous materials have unique struct…
Graphene oxide can act as an ultrahighly efficient quencher for upconversion nanophosphors and thus, an extraordinarily sensitive biosensing platform is constructed.
Halloysites/polypropylene nanocomposites with different nanotubes contents were prepared by diluting a masterbatch containing 30 wt.% halloysites with polypropylene (PP). Unmodified (HNTs) and quaternary ammonium salt treated (QM-HNTs) halloysite nanotubes were used. Both degree of crystallinity and crystallization te…
A novel dodecanuclear wheel with ten Dy(III) ions and two Co(II) ions bridged by four Schiff-base ligands and sixteen acetates represents the highest-nuclearity 3d-4f example of its type displaying single-molecule magnet behaviour.
A coumarin-spiropyran conjugate (2) shows a CN(-)-selective fluorescence enhancement under UV irradiation. This enables accurate determination of very low levels of CN(-) (>0.5 μM).
Free-standing conductive ultra-thin films based on poly(3,4-ethylenedioxythiophene)/poly(styrenesulfonate) (PEDOT/PSS) are realized. A fabrication process based on a modified Supporting Layer technique is proposed that provides for the easy production of conductive nanofilms having a very large surface area with typic…
A metafilm is a type of metasurface, a two-dimensional equivalent of a metamaterial, and is essentially a surface distribution of electrically small scatterers arranged in a judiciously chosen pattern. In previous work, we have shown that the most appropriate way to characterize a metafilm is by its effective electric…
Water-soluble, monodispersed, and bluish green-emitting Au(10) nanoclusters were synthesized through a simple reaction, in which histidine served as both a reducing agent and a protecting ligand. UV-visible absorption, photoluminescence, electrospray ionization (ESI) mass spectrometry, and X-ray photoelectron spectros…
We report the synthesis of self-organized titania nanotubes and nanocrystalline titania powders employing an alternative and novel approach. Integrating these nanostructures in a binder-free working electrode improved the capacitance up to 911 μF cm(-2), which is around one to two orders of magnitude higher than the c…
The monocrystal elastic behaviours of twenty four hexagonal close packed (HCP) metals at room temperature are reviewed based on published values of their monocrystal elastic constants. In particular, the angular variation of the Young’s Modulus (E) and the Rigidity (Shear) Modulus (G) are determined using general equa…
The tensile tests and the Erichsen tests at room temperature have been performed on seven kinds of Mg alloys: Mg-1.5Zn, Mg-1.5Zn-0.1Ca, Mg-3Zn, Mg-3Zn-0.1Ca, Mg-3Al, Mg-3Al-0.1Ca and Mg-1Al-1Zn-0.1Ca-0.5Mn alloys. In the Mg-Zn alloys, the 0.2% proof stress at 90°, which was the angle between the tensile direction and…
BACKGROUND: With the increasing use of nanomaterials, the need for methods and assays to examine their immunosafety is becoming urgent, in particular for nanomaterials that are deliberately administered to human subjects (as in the case of nanomedicines). To obtain reliable results, standardised in vitro immunotoxicol…
We report the observation of liquid crystals formed by giant graphene oxide flakes (aspect ratio above 10 000) suspended in water. As their concentration increases, the flakes undergo transitions from an isotropic dispersion to a biphasic system and then to a discotic nematic liquid crystal. The gel-like liquid crysta…
A simple and economical citrate-mediated hydrothermal route has been developed to fabricate three-dimensional hierarchical ZnO microarchitectures with high surface-to-volume ratio and large population of unconventional (0001) surface planes. This complex architecture with flowerlike morphology is assembled by many int…
Dispersion of graphene in a polymer matrix as mono layers is an important step towards fabricating high performance polymer–graphene nanocomposites. In this paper, a novel method based on Pickering emulsion polymerization has been introduced that assures fine dispersion and enhances loading. The major idea is to use a…
