Melanoma is a life threatening disease with a growing incidence rate. It is estimated that 9840 patients will die from melanoma in 2014. Despite numerous attempts for treating metastatic melanoma, conventional therapies including systemic chemotherapy or immunotherapy, either as single agents or combined, have not bee…
We have designed and synthesized the colorimetric chemosensor through the reactions of 2-(4H-chromen-4-yildene)malonitrile and 4-imidazolecarboxaldehyde. Due to its well conjugated D-π-A system and the existence of NH- fragment in structure, we expected that the chemosensor can detect anion using NH- fragment in the i…
When non-covalently bonded crystalline inclusion compounds (ICs) are formed by threading the host cyclic starches, cyclodextrins (CDs), onto guest polymer chains, and excess polymer is employed, non-stoichiometric (n-s)-polymer-CD-ICs, with partially uncovered and “dangling” chains result. The crystalline host CD latt…
Apoptosis induction provides a promising strategy for tumor gene therapy. Non-invasive ultrasound is a novel non-virus transfer method. In the field of cancer therapy, it has been found that ultrasound alone or together with microbubble represents an appealing, efficient and novel technique, which could deliver therap…
Liquid–liquid equilibrium (LLE) data for aqueous two-phase systems (ATPSs) composed of sucrose, Triton X-114, and water were determined at 288 K, 293 K, and 298 K. At 293 K and 298 K, the top and bottom phases of the ATPS were enriched with sucrose and Triton X-114, respectively. However, phase inversion was observed…
Silver nanoparticles were obtained by picosecond laser ablation in water at 1064 nm, using focusing geometry to design the particles size. The position of the target surface with respect to the focal point strongly influences the NPs size: above and in the focus it is up to 20 nm and below focus LT = 150 nm. Generated…
In depositing Bi2Se3, Bi2Te3 or Sb2Te3 layers on certain substrates by hot wall epitaxy, the Bi and Sb atoms in the layers are replaced by the atoms supplied from the substrates. We extend our exploration on this substitution phenomenon for a number of combinations of the layer and the substrate to infer the factors t…
The objective of this study was to characterize our designed through-thickness perfusion bioreactor which could generate large scaffold-free tissue engineered cartilage constructs. The hypothesis being that through-thickness perfusion could accelerate maturation of scaffold-free tissue engineered cartilage, grown in t…
The development of a stellarator–mirror fission–fusion hybrid concept is reviewed. The hybrid comprises of a fusion neutron source and a powerful sub-critical fast fission reactor core. The aim is the transmutation of spent nuclear fuel and safe fission energy production. In its fusion part, neutrons are generated in…
ABSTRACT A CO2‐switchable polymer surfactant was synthesized with 2‐(dimethylamino)ethyl methacrylate and butyl methacrylate. The conductivity, ζ potential, and particle size change illustrated the switchability of the surfactant, and this change could be repeated. Its surface tension decreased sharply when the sample…
Graded anisotropy magnetic materials possess a coercive field changing laterally with position. A simple fabrication procedure to produce such an anisotropy gradient in a polycrystalline Au/Co layer system without lateral thickness variation and with perpendicular magnetic anisotropy, prototypical for a large variety…
Modern 3D electron microscopy approaches have recently allowed unprecedented insight into the 3D ultrastructural organization of cells and tissues, enabling the visualization of large macromolecular machines, such as adhesion complexes, as well as higher-order structures, such as the cytoskeleton and cellular organell…
A rarely observed example of post-synthetically increasing pore space, while retaining the chemical functionality of the original metal–organic framework is reported. Conventional solvothermal heating in air was used to effect an efficient post-synthetic rearrangement of a bisallyloxy-tagged zinc metal–organic framewo…
Recently, Ailanthus altissima wood has received increased attention in China. Although Ailanthus altissima has a number of advantages, such as fast-growing character and high density, the low dimensional stability is a restraining factor. Chemical modification could be a feasible way to overcome such drawbacks. The ai…
Trivalent impurity ions are clustered easily in fluoride crystals. With the addition of Y 3+ spectral properties are greatly enhanced. Low temperature absorption and emission spectra are performed to unfold the optical centers in Nd 3+ ,Y 3+ :CaF 2 crystals. The strongest absorption line at around 790 nm belongs to M…
A novel cyclohexanone hydrothermal method had been firstly adopted to synthesize LiMn2O4, which was then modified with carbon coating through a post-heat treatment. X-ray diffraction (XRD) and scanning electron microscopy (SEM) exhibited that the particles were well-distributed and the primary grains were about 0.8 μm…
Fabrication of bioactive and mechanical matched bone substitutes is crucial for clinical application in bone defects repair. In this study, nano-hydroxyapatite/polyamide (nHA/PA) composite was coated on injection-moulded PA by a chemical corrosion and phase-inversion technique. The shear strength, gradient composition…
Surfaces are often coated with paint for improved aesthetics and protection; however, additional functionalities that impart continuous self-decontaminating and self-cleaning properties would be extremely advantageous. In this report, photochemical additives based on C60 fullerene were incorporated into polyurethane c…
Nb–V additions clearly affected the precipitation state, respective phase transformations and final microstructure, and in turn, resulting mechanical properties of an intercritically annealed transformation induced plasticity sheet steel. As the precipitation hardening played a limited role in the overall strengthenin…
We demonstrate experimentally the modulation and switching of one light beam by a second beam using metamaterials constructed from arrays of plasmonic circuits. Each circuit consists of three gold nanorods that mix together two coherent but orthogonally polarized light beams leading to modulation by an interference ef…
