Fabrication of nanocrystalline Mg 2Si via ball milling process: Structural studies
(2012)
In this work, nanocrystalline Mg 2Si material was fabricated via wet ball milling process using n-hexane as process control agent. Milling parameters, with emphasis on milling time and ball size, and conditions were studied ...
A2Bi8Se13 (A = Rb, Cs), CsBi3.67Se6, and BaBi2Se4: New ternary semiconducting bismuth selenides
(2001)
Rb2Bi8Se13 (I), Cs2Bi8Se13 (II), CsBi3.67Se6 (III), and BaBi2Se4 (IV) were synthesized by direct combination reactions of the A/Se (A = Rb, Cs, Ba) and Bi2Se3 at ≥650 °C. Their structures were determined by single-crystal ...
Resistive switching phenomena in Li xCoO 2 thin films
(2011)
A substantial resistive switching of Li xCoO 2 mixed-conductor thin films is observed for the first time. The occurrence of possible bipolar switching in these oxide thin films is by current-voltage curves, investigated ...
Computational predictions of the tensile properties of electrospun fibre meshes: Effect of fibre diameter and fibre orientation
(2008)
The mechanical properties of biomaterial scaffolds are crucial for their efficacy in tissue engineering and regenerative medicine. At the microscopic scale, the scaffold must be sufficiently rigid to support cell adhesion, ...
Fabrication, characterization, and evaluation in drug release properties of magnetoactive poly(ethylene oxide)-poly(l -lactide) electrospun membranes
(2013)
The fabrication of electrospun magnetoactive fibrous nanocomposite membranes based on the water-soluble and biocompatible poly(ethylene oxide) (PEO), the biocompatible and biodegradable poly(l-lactide) (PLLA) and preformed ...
Superhelices of poly[2-(acetoacetoxy)ethyl methacrylate]
(2004)
Poly[2-(acetoacetoxy) ethyl methacrylate] (PAEMA) homopolymers were found to self-assemble into hierarchical superstructures, that is, double-stranded helical tubes of either screw sense (scanning force microscopy). Both ...
Scaling rules for diffusive drug delivery in tumor and normal tissues
(2011)
Delivery of blood-borne molecules and nanoparticles from the vasculature to cells in the tissue differs dramatically between tumor and normal tissues due to differences in their vascular architectures. Here we show that ...
Synthesis, characterization, and study of octanuclear iron-oxo clusters containing a redox-active Fe4O4-cubane core
(2008)
A one-pot synthetic procedure yields the octanuclear FeIII complexes Fe8(μ4-O)4(μ-pz*) 12X4, where X = Cl and pz* = pyrazolate anion (pz = C3H3N2-) (1), 4-Cl-pz (2), and 4-Me-pz (3) or X = Br and pz* = pz (4). The crystal ...
Crystal/glass phase change in KSb5S8 studied through thermal analysis techniques
(2004)
The reversible crystal-glass and glass-crystal transitions discovered in KSb5S8 were studied in detail with nonisothermal scanning calorimetry techniques. When cooled, molten KSb5S8 becomes a metastable glass, which can ...
Normalization of tumour blood vessels improves the delivery of nanomedicines in a size-dependent manner
(2012)
The blood vessels of cancerous tumours are leaky and poorly organized. This can increase the interstitial fluid pressure inside tumours and reduce blood supply to them, which impairs drug delivery. Anti-angiogenic ...
