Abstract Surface functionalization of highly bioresorbable biomaterials has been a challenging subject. The objective of our research is to establish a calcium phosphate (CaP) coating technique on a bioresorbable bone substitute material: hydroxyapatite and collagen nanocomposite for surface functionalization using su…
The interactions between colloidal wood pitch and various commercially available mineral particles were assessed. The experiments were conducted by adding PCC, GCC, kaolin, and bentonite particles to laboratory-made pitch emulsions, and the mixtures were analyzed using flow cytometry. The results showed that most of t…
Wie durch Zauberei: Hydroxypentaarylborazin-Moleküle organisieren sich auf Cu(111)-Oberflächen in kleinen Clustern (siehe Struktur), während symmetrische Hexaarylborazin-Moleküle große Inseln bilden. Simulationen sprechen dafür, dass die beobachteten „magischen“ Clustergrößen aus einer langreichweitigen Coulomb-Abstoß…
Protective egg capsules from whelks (intertidal marine gastropods) were recently demonstrated to derive their impressive mechanical behavior—reminiscent of the pseudoelastic behavior in some alloy systems from a reversible phase transition of component protein building blocks from a compact α -helical conformation to…
In this paper, a method based on applying Successive Over-Relaxation (SOR) to find the solution of 2-Dimensional Bio-Heat Transfer Problem (2DBHTP) on a distributed computing environment using Input File Affinity Measure (I aff ) with Message Passing Interface (MPI) is introduced. A finite difference discretization is…
Molecular dynamics simulation has been performed to explore the structural and dynamical properties of undercooled FeNi melt based on the embedded atom method (EAM), namely due to G. Bonny. The simulated partial pair correlation function (PPCF) and coordination number (CN) of liquid FeNi indicate that no stronger inte…
Large-area arrays of magnetic Ni80Fe20 cylindrical nanoshells, nanocups, and perforated nanocups were synthesized using oblique deposition into topographical templates patterned using laser interference lithography. The geometry of the template and the tilt angle of the sample during deposition provide versatile contr…
A recent boson-fermion (BF) binary gas mixture model is extended to include: (i) anisotropy of the BF interaction and (ii) momentum-independent Coulomb repulsions. It is applied to account for the peculiarities of the pseudogap observed as function of absolute temperature T and concentration x of holes doped onto the…
Potted electronics are becoming more common in precision-guided smart munitions designs due to the requirements for miniaturization and structural-robustness. In most of these applications, the potted electronics are inactive for most of their lifetime and may be stored without environmental (temperature and humidity)…
Abstract The long‐chain ligand, 1‐phenyl‐3‐methyl‐4‐heptanoyl‐pyrazol‐5‐one (HL) and its zinc(II) complex ZnL2 were synthesized. The structure and the properties of ZnL2 were characterized by elemental analysis, IR spectroscopy, X‐ray diffraction, and thermogravimetric analysis. The zinc ion is five‐coordinated in a s…
We present a method for retrieval of cells encapsulated in alginate-polyethersulfone (AP) microcapsules. AP microcapsules consist of alginate hydrogel core and a semi-permeable polymer membrane. Proposed method is based on chemical destruction of microcapsule structure that is, polymer membranes are removed by dissolu…
CONTEXT: Multi-drug resistance (MDR) constitutes a major obstacle in the effectiveness of chemotherapy. P-Glycoprotein (P-gp), the product of ABCB1 gene, is a transmembrane transporter that actively pumps cytotoxic drugs out of tumor cells resulting in MDR. OBJECTIVE: We sought to establish an MG63/DOX cell xenografts…
Abstract Red-emitting Eu3+-doped indium gallium zinc oxide (IGZO) transparent thin films were fabricated using sol–gel method under UV (254-nm irradiation) in nitrogen atmosphere (inside the glove box) and thermally annealed at 500°C for 1 h. Structure, morphology, composition, and optical properties of the materials…
We have investigated the photophysical properties of star-shaped oligothiophenes with three terthiophene arms (meta to each other, S3) or six terthiophene arms (ortho-, meta-, and para-arranged, S6) connected to an ethynylbenzene core to elucidate the relationship between their molecular structure and electronic prope…
Simulations by dissipative particle dynamics revealed a possibility to produce micelles of diverse morphologies via irreversible end-coupling reaction in polymer melts containing a particulate phase. It is demonstrated that the reaction at the surface of a polymer A droplet immersed in a melt of polymer B leads to the…
GaN-based light-emitting diodes (LED) on a patterned sapphire substrate with a novel hybrid atomic layer deposition (ALD)-TiO 2 Al 2 O 3 distributed Bragg reflector (DBR) and Ag mirror have been proposed and fabricated. Due to the excellent thickness uniformity of ALD for the proposed reflector, high reflectivity over…
The catalysts TiO 2 and TiO 2 doped with Fe and V were prepared using the sol–gel method. TiO 2 -modified samples were obtained in the form of a thick film on pyrex glass sticks and tubes and were used as catalysts in the gas phase photo-oxidation of p-xylene. The physico-chemical characteristics of the catalysts were…
Free radicals are chemicals that play roles in the etio-pathogenesis of ischaemia-reperfusion injury. Various antioxidants have been used in an attempt to mitigate the damage induced by these chemicals. In the present study, the antioxidative effects of grape seed extract (proanthocyanidin), tomato extract (lycopene),…
Reflective imaging systems are typically limited to small field angles in order to avoid overly large obscurations or off-axis aberrations. Reflective optics are often preferred in astronomy due to the associated lower weight and cost, as well as the absence of chromatic aberrations. Although these advantages are comp…
Bulk heterojunction solar cells made by vacuum co-evaporation of polythiophene (PTh) and fullerene (C60) are reported and the blend morphology control through donor-acceptor composition and post-situ annealing demonstrated. Co-deposited heterojunctions are shown to generate about 60% higher photocurrents than their th…
