To improve the hydrophilicity and reduce the aging effect, argon and oxygen mixtures were employed in the plasma treatment of low-density polyethylene (LDPE). Argon resulted in producing more oxygen ions and radicals in the plasma than only oxygen and forming cross-linked layers on the LDPE surface. Therefore, the wat…
Mutations in the genes that code for collagen VI subunits, COL6A1, COL6A2, and COL6A3, are the cause of the dominantly inherited disorder, Bethlem myopathy. Glycine mutations that interrupt the Gly-X-Y repetitive amino acid sequence that forms the characteristic collagen triple helix have been defined in four families…
Violet-blue emission from novel aromatic bis(diazaborole)s, which were synthesized by the reaction of 2,5-bis(hexyloxy)-1,4-phenylenediboronic acid and 1,2-phenylenediamine derivatives or diaminonaphthalene derivatives, is described. White-blue emission from a 4-methoxy-1,2-phenylenediamine-derived molecule was observ…
We have conducted a broad survey of switching behavior in thin films of a range of ferroelectric materials, including some materials that are not typically considered for FeRAM applications, and are hence less studied. The materials studied include: strontium bismuth tantalate (SBT), barium strontium titanate (BST), l…
Typically, an orthodontic metal bracket is made from stainless steel. It has been shown that such metal may corrode in an acid- and chloride-rich environment. The purpose of the current study was to investigate a titanium nitride (TiN) ion-plated stainless steel orthodontic bracket's anticorrosion properties and compa…
Three topics are discussed. Enhanced anti-tumor efficacy of targeted doxorubicin-containing sterically-stabilized liposomes using an anti-beta1 integrin Fab' ligand. Use of tumor targeting with an internalizing ligand to improve the efficacy of a non-leaky cisplatin-containing sterically-stabilized liposome formulatio…
The pressure dependence of first- and second-order Raman frequencies of wurtzite ZnO has been measured up to the wurtzite-rocksalt phase transition pressure of 8.3 GPa. A small increase of the LO-TO splitting with increasing pressure is observed. This effect is related to the combined pressure dependences of the elect…
We have studied the strain rate dependence of incremental stress-strain curves of self-assembled type I collagen fibers in an effort to understand the molecular phenomena that contribute to the macroscopic mechanical behavior of tendons. Results of viscoelastic tests at strain rates between 10% and 1000% per min sugge…
In this study, the effect of plating current densities on self-annealing behaviors of electroplated Cu films was found to be relevant to the polarization resistance of electroplating systems. Porous films with defects occurred at low plating current density or at low polarization resistance. In contrast, dense films w…
A model of heat and water transfer through layered fabrics, such as wearing clothing, is developed in this paper. All particular properties of recently developed fabrics are considered: hydrophobic or hydrophilic treatment, membranes glued onto a layer. and surface modification of the textile (abrading). Physical phen…
Abstract The synthesis and spectroscopic and electrochemical properties of crown-ether substituted metallophthalocyanines (MCRPcs), optically active phthalocyanines (Pcs), subphthalocyanines (SubPcs), low symmetrical Pcs, ring-expanded Pcs, and novel oligomers of Pcs studied mainly by the author over the last 20 years…
In this paper, degree of sensitization (DOS) of austenitic stainless steels (SS) is defined in terms of the characteristic parameters of the chromium depletion zones: coverage (proportion of the grain boundary length covered by chromium depletion zones), width, and depth (the minimum level of chromium in the depletion…
Porous polyhedral silsesquioxane (POSS)-based network polymers are prepared using hydrosilation copolymerisation reactions of a silyl-functionalised POSS molecule with a vinyl-functionalised moiety. Characterisation of these solids show them to possess pore structures in the mesoporous regime, and polymers with longer…
Atomistic simulation calculations based on energy minimization techniques have been used to predict the O positional parameter of a wide range of A2B2O7 pyrochlore oxides. Cations studied range from Lu3+ to La3+ on the A site and Ti4+ to Pb4+ on the B site. In all cases the model included a specific predicted degree o…
We report on the temperature dependence of electrical resistivity, Seebeck coefficient and Hall coefficient for Fe2(V1−yTiy)Al with y=0−0.25 and Fe2(V1−zMoz)Al with z=0−0.20. While the Heusler-type Fe2VAl (y=z=0) exhibits a semiconductor-like resistivity behavior, a slight substitution of Ti or Mo for V causes a sharp…
The study of metallic foams has become attractive to researchers interested in both scientific and industrial applications. The different production methods have not been widely utilized because of difficult process control and high production costs. A new easily-available agent for metal foaming, calcium carbonate, i…
Plasticizers are usually added to improve the mechanical and conditional (thermomechanical) quality of film coatings. Different molecular weights and concentrations of polyethylene glycol were incorporated as plasticizers in hydroxypropylmethylcellulose (HPMC) films. Thermomechanical and mechanical properties of cast…

Block-copolymers are known to generate nano-scale microdomains by microphase-separation, if they are annealed at a temperature lower than their order-disorder transition temperatures. We tried to transfer microdomains onto substrates by only using the reactive-ion etching method, which is widely used in semiconductor…
The soft clay of Ariake Bay, in western Kyushu, Japan covers several hundred square kilometers. Ariake clay consists of the principal clay minerals namely smectite, illite, kaolinite and vermiculite, and other minerals in lesser quantity. The percentage of the principal clay mineral can vary significantly. The percent…
