A bottom-up tailoring methodology was developed to successfully regulate the morphology and size of novel composite micellar bunches with liquid crystal mesophases self-assembled from multivalent metal ions (ZrIV) and nonionic surfactants (P123), and subsequently the morphologies and dimensions of liquid crystal-templ…

Bi-doped red phosphor series were prepared by solid-state reactions which present bright red luminescence dominated by a transition of . With doping, the excitation bands of the phosphors extend to longer wavelength (from ), and the excitation efficiency for optimized content is dramatically increased, which favors th…
This study was carried out on 240 broiler chickens in a completely randomized design in four treatments at 0, 300, 600 and 900 pmm levels of silver nanoparticles with four repetitions within 16 separate cages. The chickens were individually weighed and recorded at the end of every week of experiment. Increase in the a…
The interactions of Cu(i) and Ag(i) ions with four star-shaped ligands, 2,4,6-tris(N-7-azaindolyl)-1,3,5-triazine (tat), 1,3,5-tris(N-7-azaindolyl)benzene (tab), 2,4,6-tris(2,2'-dipyridylamino)-1,3,5-triazine (tdat) and 1,3,5-tris(2,2'-dipyridylamino)benzene (tdab) have been investigated by X-ray diffraction, NMR and…
The wide array of tissue-engineering applications enhances the need for biodegradable materials with broad potential. Chitosan, the partially deacetylated derivative of chitin, may be one such material. This research studies the morphology and characterization of porous structures produced from chitin for use as a sca…
Recently, the Ti-Zr-Nb alloys have been developed as Ni-free shape memory and superelastic alloys. In this study, the effects of Nb and nitrogen (N) contents on martensitic transformation behavior, shape memory effect and superelasticity in Ti-18Zr-(12∼16)Nb-(0∼1.0)N (at%) alloys are investigated using loading and unl…
The 3D morphology and distribution of lenticular Ni(4)Ti(3) precipitates in the austenitic B2 matrix of a binary Ni(51)Ti(49) alloy has been investigated by a slice-and-view procedure in a dual-beam focused ion beam/scanning electron microscope system. Due to the weak contrast of the precipitates, proper imaging condi…
In this study, thermally reversible polyurethanes (PUs) with shape memory effect were developed by using hydrogen bonding to enhance physical interactions. Two different types of PUs were synthesized: (1) a linear PU whose hard segment consists of methylene di-para-phenyl isocyanate (MDI) and di(ethylene glycol) (DEG)…
Carboxymethyl cellulose (CMC) is systematically investigated for the first time in regulating the CaCO3crystallization using a biomimetic gas-diffusion method. Monodisperse rosette-like calcite spherules in uniform size with their surfaces composed of rhombohedral subunits were synthesized in certain conditions. Accor…
We have demonstrated that fibrillar aggregates formed from the self-assembly of a dumbbell-shaped rod amphiphile undergo a reversible chiral-non-chiral transition triggered by temperature.
Sepiolite is a clay mineral with a fibrous morphology; the fibers possess rectangular channels along the fiber direction, and have cation-exchange ability. Amphiphilic octadecylammonium cations (ODAH(+)) spread at an interface between the air and a dispersion of sepiolite fibers have hybridized with the fibers to form…
Artificial left-handed metamaterial (LHM) provides a new perspective for microwave hyperthermia. Four flat LHM slab lenses can be used to form a focus-flexible applicator for breast tumour hyperthermia. By adjusting microwave sources behind the four flat LHM lenses, microwaves emitted from the sources can be focused t…
Macrocyclic aromaticity is one of the key concepts in porphyrin chemistry. The degree of macrocyclic aromaticity and the associated main macrocyclic conjugation pathway in Hückel- and Möbius-type porphyrinoids were determined using our recently proposed procedure based on bond resonance energy (BRE). All porphyrinoids…
A series of side-chain liquid crystal polymers based on an azobenzene mesogenic unit bearing a terminal chiral chain has been synthesized. The thermal and mesomorphic properties of the homo- and copolymers have been investigated by polarizing optical microscopy, DSC and X-ray diffraction. Polymers having a chiral meth…
The potential of tyrosinases to activate tyrosine residues of wool protein fibres for cross-linking with different materials like collagen, elastin and gelatine was assessed. Natural fibres like wool offer an excellent environment for the growth of micro-organisms when the conditions like moisture, oxygen and temperat…
We synthesized AgGaTe2, AgGa5Te8, AgInTe2, and AgIn5Te8 by solid-state reactions of Ag2Te, Ga2Te3 or In2Te3, and Te, and prepared their high-density polycrystalline pellets. The thermal conductivity κ was evaluated by the laser flash method from room temperature to around 870 K. These compounds exhibited low κ, e.g. t…
Eu(3+)-doped transparent glass ceramics containing In(2)O(3) nano-crystals were prepared by melt quenching and subsequent heating. X-ray diffraction analysis, transmission electron microscope observation, and photoluminescence excitation spectra demonstrated that In(2)O(3) nano-particles sized 3-6 nm homogenously dist…
The luminescence of certain lanthanides can be obtained in full if the metals are chelated to a suitable chromophor (antenna effect). This phenomenon may be achieved within the body of a porous solid. There are many examples in the literature regarding this approach. The present paper accounts for our recent findings…
In the present article, investigations of an unusual two-component (H-) bonded pair, i.e. the cyclohexanol-neopentylglycol system, are reported. The phase I of cyclohexanol (CHXOL) forms a continuous solid solution with the phase I of neopentylglycol (NPGOL). This binary solid solution (S(I)) has been investigated at…
