Self-hardened calcium phosphate cement (CPC) sets to form hydroxyapatite and possesses excellent osteoconductivity. However, lack of macroporosity and low strength constrain its application in bone tissue engineering. Recent studies have incorporated various fibres into CPC to improve its mechanical strength. The pres…
GMC-5-193 (GMC) is a novel anticancer small-molecule quinazolinone analogue with properties that include antimicrotubule activity and inherent fluorescence. The aim of this study was to produce and optimize a systemically administered liposomal formulation for tumor-targeting delivery of GMC to enhance the anticancer…
The validity of various simplified treatments of anisotropic scattering is investigated in typical LWR configurations that simulate PWR, BWR, and APWR. In addition to the explicit treatment of anisotropic scattering, the diagonal approximation of anisotropic scattering matrixes and the transport corrected cross sectio…
Highly photoconducting β-In2S3 thin films with conducting grain boundaries were obtained, using “chemical spray pyrolysis” technique. By varying the atomic ratio of the precursor solution used for spray pyrolysis, the photoconductivity of these films could be tailored. Conducting grain boundaries were found only for s…
In this work, poly ethylene glycol (pEG) was used as a cosolvent to control the morphology of transition metal substituted aluminophosphate molecular sieve AlPO 4 -5 (AFI) crystals in the solvothermal reaction system of Al(OPr i ) 3 -H 3 PO 4 -TEA-Me-H 2 O-pEG (Me = Cr, Ti, Fe, V). In the presence of pEG molecules, th…
Recently different types of fluorescent nanoparticles and other nanostructures have been promoted as alternatives for the fluorescent organic dyes that are traditionally used in biotechnology. Quantum dots, dye-doped polymer and silica particles have found many applications in biochemical protocols and are extensively…
In this paper, an experimental study was conducted to study susceptibility to flex cracking of multilayer ceramic capacitors (MLCCs), in which a comparison was made between identical samples which were assembled using either Pb-free (Sn3.0Ag0.5Cu) or eutectic tin-lead (Sn37Pb) solder. Flex testing was performed on MLC…
The device performances of green phosphorescent organic light-emitting diodes with a triplet mixed host emitting layer were correlated with the energy levels and composition of the host materials. Two hole-transport-type host materials, (4,4′-N,N′-dicarbazole)biphenyl (CBP) and 4,4′,4″-tris(N-carbazolyl)triphenylamine…
In statistical mechanics, the equilibrium properties of a physical system of particles can be calculated as the statistical average over accessible microstates of the system. In general, these calculations are computationally intractable since they involve summations over an exponentially large number of microstates.…
The purpose of this investigation was to evaluate dorsal root ganglion (DRG) cell outgrowth in a biosynthetic material made from PEGylated fibrinogen and in thrombin-polymerized fibrin hydrogels. The hypothesis stipulated that changing the composition of the biosynthetic constituents of the hydrogel can be used to bet…
A metal injection moulding technique for the production of aluminium alloy components is described. A part is formed by injection moulding a mixture of alloy 6061 and 2 wt-%Sn with a resin consisting of stearic acid, palm oil wax and high density polyethylene. The resin is removed by a combination of solvent and therm…
Gigacycle fatigue behavior in high-strength steels tested under rotary bending fatigue was summarized in this paper. Characteristic of the very high cycle fatigue is to be caused the transition of fracture mode from surface-induced fracture to subsurface inclusion-induced one. In the vicinity of an inclusion at the or…
In this work, insoluble multi‐walled carbon nanotubes (MWNTs) was dispersed into ethanol in the presence of 1% Nafion, resulting in a stable and well‐distributed MWNTs/Nafion suspension characterized by TEM and particle size analyzer. After evaporation of ethanol, a uniform MWNTs/Nafion composite film‐coated glassy ca…
The synthesis of konjac glucomannan-graft-polyacrylamide (KGM-g-PAM) was carried out at 25 degrees C by gamma-irradiation under a N2 atmosphere. The effects of absorbed radiation dosage and monomer concentration on grafting yield and water absorbency were studied. The grafted copolymers were characterized using Fourie…
Abstract Fabrication of a large area of periodic structures with deep sub-wavelength features is required in many applications such as solar cells, photonic crystals, and artificial kidneys. We present a low-cost and high-throughput process for realization of 2D arrays of deep sub-wavelength features using a self-asse…
Abstract Over the last 40 years we have witnessed an impressive development of the tools for the analysis of polymer surfaces. However, there still are questions, which are very challenging and the quest of answering these questions means working at the frontier of current science. We discuss some general features of…
The understanding of D-amino acid metabolism in higher plants lags far behind that in mammals, for which the biological functions of these unique amino acids have already been elucidated. In this article, we report on the biochemical behavior of D-amino acids (particularly D-Asp) and relevant metabolic enzymes in Arab…
We have devised a bioreactor to simulate normal urinary bladder dynamics. The design permits a cell-seeded scaffold made from a modified porcine acellular matrix to be placed between 2 closed chambers filled with culture medium and be mechanically stimulated in a physiologically relevant manner. Specifically designed…
Supersaturating drug delivery systems (SDDS) utilize two important design elements in their preparation including converting the drug of interest into a high energy state or other rapidly dissolving form to facilitate the formation of supersaturated drug solutions and providing a means for stabilizing the formed super…
While in the last years applications of carbon nanotubes in the field of biotechnology have been largely proposed, biomedical applications of boron nitride nanotubes (BNNTs) are yet totally unexplored. BNNTs have very interesting physical properties that should be exploited in the biomedical field. At this date, studi…
